How do blind people get around safely Some people use special guide dogs. A well-trained dog knows how to help its owner cross busy streets and get from place to place. Some people use long white canes (手杖) to help them get around.
Guide dogs and canes are helpful, but there must be a better way for blind people to get around. A scientist in England thought so. His name is Waters and he studies bats (蝙蝠) . He knows that bats are able to fly in the dark. Besides, he knows that bats go by using sound to “see”. Dr. Waters wondered if people could do something similar.
Bats make sounds as they fly. These sounds travel in waves (波) in the air. When the waves hit an object such as a tree or house, they bounce back (反射回来) . The waves travel back to the bat’s ears. A bat learns the location and shape of objects around it.
Dr. Waters talked to other scientists, including Withington from America and Hoyle from Germany. They worked together and invented a new kind of cane. They called it a “bat cane” because their idea started with bats. The new cane has a computer in the handle (手柄) . ________The sound waves hit objects and echoes (回声) back. This causes the handle to make sounds, which humans can hear.
With a little training, a person using the cane can easily tell where objects are and can “see” with sound!
1．A _____ helps the blind go across busy streets.
A．bat B．black cane C．computer D．well-trained dog
2．Scientists called this new kind cane a “bat cane” because________.
A．it looked like a bat B．a bat had been trained
C．their idea began with bats D．they thought bats may bring good luck to the blind
3．Which of the following can be put in “________” in the fourth paragraph
A．It makes noise that helps humans B．It produces some songs that humans can hear
C．It sends out high sounds that humans cannot hear D．It tells the blind that there isn’t anything around them
4．The bat cane may make the blind’s life________.
A．funnier B．more exciting C．more difficult D．more convenient
Searching for parking spaces has long been a headache for many office workers in many big cities of China, especially for those working in central business districts. Parking near their companies for five days a week could cost them a lot of money. At the same time with prices for parking lots in residential (居民区) rising, most of their spaces remain idle during workdays.
Now a new form of sharing economy has appeared in China—the shared parking space. It has become a huge market in some big cities. In Qingdao, a coastal city in Shandong, up to 10,000 personal parking spaces have been turned into shared ones with the help of “Airparking”, an online shared parking platform developed by a network company from Guangzhou.
Users can share and order a parking place by downloading and using a special app. Owners who have idle parking spaces can share some information, such as the parking position, license number and time limit on the platform. With the information, users can easily find the nearest place to park. The average parking cost for shared parking is 4 yuan each hour, almost the same as the service cost in traditional parking spaces.
Qingdao is one of the Chinese cities that encourage shared parking. Some other big cities, like Beijing, Shanghai and Hefei, have also begun to try this idea. The Shanghai government, for example, has set up more than 6,500 shared parking spaces to encourage the public to use. Shared parking will be more and more helpful to the drivers.
5．What does the writer point out in Paragraph 1
A．The cost of parking. B．The spaces of parking.
C．Ways of parking. D．Difficulties of parking.
6．The underlined word “idle” probably means ________ in Chinese in paragraph 1.
A．懒散的 B．降价的 C．闲置的 D．废弃的
7．If you want to use shared parking in Qingdao, you should ________.
A．download and use a special app B．share your personal information
C．have a parking space of your own D．work in central business districts
8．What can we infer from the passage
A．Qingdao has fewer shared parking spaces than Shanghai.
B．Shared parking will probably become more and more popular.
C．Shared parking is less expensive than traditional parking service.
D．It’s hard to find parking spaces in residential areas during workdays.
Scientists have created a new tool that can turn people’s thoughts into words. It works by using an AI program called GPT-1 to translate brain activity words. In order to achieve this, scientists did a lot.
First, scientists got everything ready before the tests. They invited some volunteers. Each spent sixteen hours listening to stories in a scanner (扫描仪). They imagined the stories as they heard them.
Then came the tests. The scientists did them in three different ways.
Test 1
The researchers played a new story. GPI-1 was only given recordings of the volunteers’ brain activity. But the words that GPT-1 predicted were very similar to the words in the story that they were listening to. The words weren’t exactly the same, but they often carried the same meaning. For example, when a volunteer was listening to a story about a woman who didn’t have a driver’s license (驾照).
Test 2
The scientists also carried out the test when volunteers imagined their own stories. “It really works at the level of ideas. The ideas are the same but expressed in different words.” says Alexander Huth, one of the scientists behind the study.
Test 3
The researchers showed the volunteers silent movies, with no spoken words at all. GPT-1 could still work out the basic ideas.
After the tests,the scientists say that GPT-1 is the first AI program to turn what people are thinking into words without brain surgery (外科手术). The tool isn’t something that can be easily used today, they believe, a similar but cheaper tool could help people who have lost the ability to speak because of an injury or disease.
The scientists say their tool can’t be used to “read people’s minds” without permission (允许). The tool only works if the person wants to share their thoughts.
9．What can GPT-1 do
A．Produce silent movies to test the scanner. B．Catch the ideas of stories to tell volunteers.
C．Turn recordings of brain activity into words. D．Record brain activity to work out the picture.
10．Why did scientists do the tests
A．To explain how the tool works. B．To show that the tool works well.
C．To test where the tool can be used. D．To study whose mind can be read.
11．In which way was information put into volunteers’ brain in Test 3
A．Listening. B．Imagining. C．Watching. D．Reading.
12．Who could GPT-1 help according to the passage
A．People who can’t speak. B．People who can’t hear. C．People who can’t read. D．People who can’t drive.
Who invented the umbrella There are many different opinions. Some people say that the people of ancient Egypt invented it, some say the Romans invented it and some say Luban’s wife invented it in ancient China. There’s even an interesting story about its invention in China.
Luban was the most famous craftsman in ancient China. One day, Luban and his wife were taking a walk and enjoying the beautiful view. Suddenly it began to rain. Both of them were soaked when they got back home. Luban’s wife said, “If there is something that can protect people from the rain when they are walking outdoors, it will be wonderful.” Then Luban said, “That’s easy. I will build many pavilions (亭).” His wife replied, “That’s a good idea, but it is not convenient. Is it possible to make a movable pavilion, which could always follow the people ” She thought all day and all night. One day, she saw some kids playing in the rain, and each kid held a big lotus (莲) leaf over the head to protect themselves from getting wet. That gave her a great idea. Then, she made the first umbrella in ancient China.
Since the umbrella was invented, it has been part of people’s life in every corner of the world. Right now, there are many kinds of umbrellas, such as beach umbrellas, kids umbrellas and market umbrellas.

Bi Sheng was born in Song Dynasty. He lived in a small village which lies in Huanggang today. He invented the printing around 600 AD (公元). He was the world’s first inventor of the printing. It is about 400 years earlier than the printing in Germany.
The printing is also called the movable type printing (活字印刷). But how did it work in the past
First of all, the clay was made into movable types. Then words were engraved (雕刻) carefully onto the types. After that, the words were chosen and put in right order in a box according to the text. Next, the workers brushed ink onto the movable types. Finally the types could be used for printing. They could be used again and again for different books.
The movable type printing plays an important role in Chinese culture. With the help of it, Chinese culture spread around the world more quickly. At the same time, the movable type printing was widely used in the world at that time. As a result, more and more culture communication among countries took place. The movable type printing, the compass (指南针), gun powder and the paper- making are called four great inventions of China. They make China own an important and even top position in the history of human civilization (文明).
17．When was the movable type printing invented
A．About 600 years ago. B．Around 600 AD． C．Before Song Dynasty.
18．What should the workers do after the words were chosen and put in right order
A．Brush ink onto the types.
B．Make the clay into movable types.
C．Print by using the types.
19．What does the word “it” in Paragraph 4 refer to
A．The compass. B．Gun powder. C．The movable type printing.
20．What’s the passage mainly about
A．Four great inventions and their position in the history of human civilization.
B．Bi Sheng invented the movable type printing after trying many times.

Last week, my family and I went to a science museum. It’s such a famous museum that it interested quite a lot of visitors. What surprised me was that there were many kinds of robots there. I could find robots for cooking and robots that you could play chess with. Nowadays researchers in China have developed and made the world’s first robot whale shark (鲸鲨).
The underwater robot is 4.7 meters long, weighs 350 kilograms and can swim for 42 meters per minute. It can move like a real shark by moving its mechanical fins (机械的鳍) with the help of a battery (电池). Its mouth can open and close like a real shark’s.
“The robot can reach a depth of 10 meters and work for 13 hours,” said Mr. Fang, a leader in control of the robot shark program.
Having observed the huge market for underwater robots, a factory decided several years ago to develop robotic animals that live in water. The company has built many kinds of robot fish. The robotic whale shark is the largest mechanical fish they have made so far.
Mr. Fang also said, “Our robots are to serve three purposes. They are providing visitors with joy, spreading knowledge about the sea and finishing scientific tasks such as environmental checks and underwater photography.”

Have you ever seen or used a saw, or “ju” in Chinese Do you know who invented it
The inventor was Lu Ban. He was born in the state of Lu in ancient China more than 2,500 years ago. That is where Qufu lies in the east of Jining.
Lu Ban was the greatest carpenter (木匠) in his time. Once the king ordered him and his team to build a palace in a very short time. They would be punished if they missed the deadline (最后期限). They had only axes, or fuzi in Chinese, to cut the trees and prepare the wood for the palace, so work was very slow.
One day Lu Ban rushed up the hill to see how things were going. Suddenly the sharp teeth of a leaf cut his hand. Then a bright idea came into his head. Soon he made a tool with teeth along the side of a long iron bar (条状物). With this tool, work became much faster, and they completed the work before the deadline.
That is how the saw was invented.
Lu Ban invented many other useful tools for carpenters and interesting toys for children. The Wooden Bird, for example, could stay in the air for three days. That’s why he is regarded as the God of Carpentry.

Alfredo Moser is a Brazilian worker who is skilled at repairing machines. His wife says her husband has always been handy (手巧的) at home and made tables and chairs. Alfredo has invented a way of lighting his house during the day without electricity.
He has been using plastic bottles filled up with water and a little bleach (漂白剂) to provide dark rooms with light for many years. And the idea has now spread across the world. It is predicted that his lighting system, which works using refraction (折射) of sunlight, will be fitted in over a million homes by the end of this year.
Alfredo used normal plastic drinks bottles that are often thrown away. The secret of the liquid in the bottles is the bleach added to water, which stops it turning green in the sunlight. Mr. Moser drills a hole in a roof tile (在屋瓦上钻洞) and then pushes the bottle in from below, keeping the bottle in place with polyester resin (聚酯树脂). Depending on the strength of sunlight, the light fills his home, and the bottles are just like electric bulbs of between 40 and 60 watts (瓦特).
Alfredo came up with the idea for his “Moser light” during one of the blackouts in Brazil in 2002. He said only factories had power in his home city, in southern Brazil during the energy shortage.
The local supermarket and his neighbors, houses are utilizing Moser lights. He earned a few dollars, but his invention has not made him a rich man. Now a great number of people admire what he is doing!

China is one of the biggest countries in growing tea. There are many kinds of tea, such as Oolong tea, tieguanyin, Lonjing.
In the wild, tea plants may be 9 meters tall. But a plant grown for market is pruned. Pruning keeps the plant only 0.9 or 1.2 meters tall. This is an easy height for tea picking. Only the two top leaves and bud of each new shoot are picked. So to make money, tea plantations (种植园) must be huge.
In general, there are two kinds of tea: black tea and green tea. Black tea is fermented (发酵). In the process, the tea loses nearly all of its healthy parts. Green tea is steamed right after the leaves are picked. Green tea keeps its healthy parts. For example, it may prevent heart illness.
How did we get tea bags The answer: by accident. Tea businessmen used to send samples in tin (锡) boxes. This was very expensive. One businessman thought of a cheaper way. He sent samples in small silk bags. Customers would open the bag. They would make tea as usual. One customer put the bag into a pot. Then he just poured hot water over it. And the tea bag was born.
Shen Nong was the first to drink tea. He was a Chinese emperor. Shen drank several cups of hot water daily. One day something happened. Leaves from a wild tea tree fell into the hot water pot. The next cup was poured. The water was now colored. Shen tasted it. He liked it. He drank it all. Shen was proud of his new drink. He served it to his guests. Word spread. People thought this way: tea is good enough for the emperor, so it must be good enough for the people. Tea became the drink of China.

Imagine flying over the city in an Aircraft (航空器) that had no pilot but can take you from point A to point B in minutes. Sounds like science fiction, right Well, not anymore.
China-based Ehang has become the world’s first company to fly passengers in air taxis without a pilot at the controls.
Ehang’s EH216-S air taxis can carry up to two passengers or about 270kg of goods (货物). They can fly at speeds of up to l30 km/h and distances (距离) of up to 28 km. Passengers can simply select the places they want to go to on a touchscreen and enjoy the ride without worrying about piloting the air taxis.
The taxis do not require airports or runways. They can take off and land vertically (垂直地) from any flat (水平的) surface, such as a park or car park. What’s more, the air taxis use electric power to cut down environmental harm. They can be fully charged in two hours and have low noise levels.
To make sure it is safe enough, more than 40,000 test flights have been taken in different places around the world since 2014. Then on October 15 this year, Ehang said to the public that it had got agreement from the government that the taxi is safe to fly and it can run the air taxi business with passengers in China.
Ehang’s air taxis still have some challenges. First, they need to follow the laws and rules of different countries. Another big problem is getting the trust of the public—they are safe while flying. To do this, Ehang will educate passengers about the benefits and risks of using the taxis while also dealing with problems like noise levels, privacy and the environmental influence.

Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires. There’s even one theory(理论) that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation(辐射) given off by mobile phones does great harm to bees’ navigation systems(导航系统). Bees have a built-in system a bit like BDS and this helps them find their way back to their hives(蜂巢). But recently, thousands of bees have failed to find their way home. It is believed they are dying far from their hives.
The problem was first noticed by beekeepers in America and is a lot more serious than it seemed at first. The important thing about bees is that most of the crops in many countries are pollinated by them. Without bees, crops can’t continue to grow.
Nobody knows for sure whether the theory is true or not, but it’s a fact that bees are disappearing in very large numbers. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! If the mobile phone theory is correct, we need to do something about it right now before it’s too late.
58．What might be caused by mobiles according to Paragraph 1
A．Poor listening. B．Forest fires.
C．The disappearance of bees. D．Terrible toothaches.
59．What does the theory in the passage say
A．Bees have BDS inside their bodies. B．Mobiles have an influence on bees’ hives.
C．The radiation makes bees unable to fly. D．The radiation makes bees lose their way home.
60．The underlined word “pollinated” in Paragraph 3 probably means “________” in Chinese.
A．授粉 B．污染 C．啃食 D．催熟
61．The writer writes this passage to ________.
A．call on people to help beekeepers B．show how a bee’s built-in system works
C．ask people to stop using mobiles right away D．warn people of the possible harm mobiles do to bees
In my opinion, the wheel is the most important thing that human beings have ever invented. It might seem weird to say that something so simple-looking and so ordinary (普通的) could be so important. But if you consider the following points, you will probably agree with me. Firstly, wheels influence almost every part of our lives. Wheels are used, for example, engines and transport. If you visit just one factory, you will see how important wheels are. You will see wheels on almost every machine.
Secondly, wheels play a great part in food production. Wheels are used to grind (磨碎) different kinds of corn into flour (粉状物). They are then used to mix flour and other foods into bread. We would all have to make our own bread, starting with grinding the wheat (小麦) if we did not have the wheel. In fact, we would have to grow the wheat because there would be no way to transport it.
Thirdly, our world would be completely different if we did not have the wheel for transport. Before the wheel was invented, people used to have to travel on foot or by riding on an animal. That is what we would be doing now if we did not have the wheel. Everything would take longer to do.
We would be back to the Stone Age if some of our clever ancestors (祖先) had not invented the wheel. Our modern world would simply be impossible. The wheel is surely the most important invention of all time.
62．The underlined word “weird” has the closest meaning to “________ ”.
A．important B．common C．strange D．necessary
63．What is the third paragraph about ________

The pencil is a very simple object. However, it took hundreds of people over centuries to make it what it’s like today.
The story of the pencil starts with graphite (石墨). 66 Around 1560, an Italian couple named Simonio and Lyndiana Bernacotti added wood holders to the graphite sticks. 67 In 1795, in France, Nicolas-Jacques Conte worked out a method (方法) of mixing graphite powders with clay. In this way, people made strong pencil cores (铅笔芯). 68
When pencils were handmade, they were made round. Then an American Joseph Dixon developed machines to make pencils. 69
There is a pencil for everyone and every pencil has a story. The Blackwing (黑翼) 602 is famous for being used by a lot of writers. And then, you have the Dixon Pencil Company. 70
In my opinion, there’s nothing that can be done to make the pencil better than it is.

A．However, since the graphite is too soft, the pencils were easy to break.
B．It’s what people think of when they think of a pencil and what they most probably will buy when their children are about to learn to write.
C．People cut it into small sticks and used them to write or draw.
D．Later people found out it was easier and less wasteful to make a pencil which has six sides.
E．To this day, the method is still used in making pencils.
The well-known “new great inventions” of modern China have made our daily lives more convenient.
High-speed trains
China created its first high-speed railway line in 2008. Since then, the number of passenger trips has grown by over 30 percent every year. By 2016, more than 5 billion trips had been taken on the trains. By 2020, one-fifth of the country’s 150, 000-km railway network will be used by the trains. This network will link more than 80 percent of the major cities across China.
Mobile payment
Mobile payment is turning China into a “cashless society”. Instead of paying by cash, customers now pay for their goods and some kinds of bills simply by typing a short password into the Alipay or Wechat app on their mobile phones.
Shared bikes
China has surprised the world with how quickly shared bikes are widely used. Nowadays, bike users can simply pick up or park the bikes on the street through GPS and smartphone apps. China’s two leading bike-sharing companies, Mobike and Ofo, have been opening their overseas markets in Singapore, the UK and the USA．
Online shopping
With around 751 million Internet users, China has been the world’s largest and fastest-growing online shopping market.

Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood powered or coal powered stoves.
One way to reduce the number of deaths is through cooking equipment (设备) powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the “Sol 4”. “It is four square meters of mirrors, six to eight meters in length. It is quite a large cooker.”
The “Sol 4” works by reflecting (反射) light from the sun off large mirrors. The mirrors direct (把……对准) the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.
The cooker is also much “friendlier” than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals would be less likely to have breathing illnesses from harmful smoke.
At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.
Each cooker costs about $2,000, which is a large amount of money for most Africans. To solve that problem, Crosby Menzies has created a nongovernmental (非官方) organization called Solar Cookers for Africa. It plans to raise money through donations (捐款) to provide poor people with solar cooking equipment.
79．The writer starts the passage by ________.
A．comparing facts B．sharing experiences C．listing numbers D．giving reasons
80．The underlined word “individuals” most probably means “________”.
A．cookers B．people C．mirrors D．experts

A．It is six to eight square meters of mirrors.
B．It can work in any weather condition now.
C．It can also heat the pan by lighting firewood.
D．It is more environment-friendly than other cookers.
82．From the passage, we can infer that ________.
A．the “Sol 4” will be designed in a smaller size
B．more Africans can use the solar cookers in the future
C．the “Sol 4” is the first product of the South African company
D．the African government will provide poor people with solar cooker
Facial recognition（人脸识别）cameras are everywhere, including in your phone. Many people depend on this technology to unlock（解锁）, open doors or pay for things quickly, but there is a problem: everyone is wearing masks（口罩）.
Now, the companies have improved the facial recognition technology. It can now work well even if people are wearing a mask.
A company in Beijing named Hanwang has announced that their product can correctly recognize（识别）95 percent of people wearing masks. What’s the secret
A professor at an American University studies facial recognition technology. “As getting older”, he said, “our faces change shape.”
Facial recognition software is about more than just unlocking your phone. It’s about public safety. For example, you don’t need to show an ID card, which can be lost or stolen. It also means that diseases aren’t spread by touching things. It has become especially important now because of the COVID—19. It helps with safety and peace of mind.
More than that, facial recognition can be used to fight crime（犯罪活动）. It can notice crime and terrorists. The technology is used by police in places like government buildings
There is also a weakness of this technology: it fails when people wear both a mask and sunglasses. In this situation, all of the key facial information is lost.
83．According to the passage, people depend on facial recognition technology to do the following things except ________.
A．unlocking their phones B．turning on a TV C．opening the doors D．paying for things quickly
