A school used to organize a fun trip for its students every year. This year the trip is as usual. Everyone was excited about the trip.
On the way, they must drive through a tunnel (隧道). Then they could reach their final place. On reaching the tunnel, the bus driver saw a board. It said “The height of the tunnel is 5 meters.”. The bus is also nearly 5meters high. The driver had gone through it many times, so he didn't stop the bus.
However, the bus got stuck (卡住) somewhere in the middle this time. This scared children. When teachers questioned, the bus driver said, “Every year I drive through the tunnel without any problem.”
Then a man got there, “Recently, this road has been repaired. So the level of the road has been raised a little.”
Then they tried some different usual ways, but they all failed at last. Suddenly, a child said, “Why not let out some air from tires (轮胎) ”
Everyone was amazed at the kid's wise advice and the bus came out of the tunnel safely at last. One teacher said, “_________”
1．Why must they drive through the tunnel （不超过10个词）
2．What happens to the road after being repaired （不超过10个词）
3．What might one teacher say at the end of the story （不超过15个词）
American Grace Brown is keeping busy during her first year of high school. She studies all subjects, such as English, history and math, as well as taking classes in Latin. She also sings in a school team and plays the piano. The school day lasts from about eight o’clock in the morning to three in the afternoon. But because of her many activities, Grace has no time for a class in physical education. So she is getting school credits (学分) for virtual (虚拟的) PE.
The idea, as strange as it may sound, is getting support from wearable fitness recording devices. Brown wears a fitness tracker (追踪器) called Fitbit that the school provides. She wears it on her arm while doing exercise lasting 30 minutes or longer three times a week. She usually does this outside of school hours. Her computer has a software program that records her activities which she can provide for school for credits.
A PE teacher may not be guiding the Fitbit-wearing students in person. But teachers do lead students’ work by setting goals such as fat burning, using the technology as their eyes and ears. Grace Brown has been adding light running and bicycle rides to her days. For students, it is a welcome way to take a required class that some students may find socially or physically difficult. Grace’s mother Rhonda Brown says, “These kids are burning 2,000 calories during a practice and more at every game. I wish the schools would catch up with the times.”
However, technology and the collection of any student data always cause worries about students’ private information. And some Americans worry that students exercising on their own may miss out on important social spirits such as teamwork.
4．When does Grace’s school finish in the afternoon
5．Why does Grace have no time for a PE class
6．What does Grace use while doing exercise
7．How does a PE teacher lead students’ work
8．Who worries that students may lose social spirits like teamwork

Building Schools with Bottles
By Tracy Vonder Brink
Is your school made of bricks or concrete blocks Many are. But some classrooms in Guatemala and EI Salvador were built a different way—with bottles full of trash! Hug It Forward—bottle schools use plastic bottles, trash, and lots of community helpers. Let’s see how they do it!
First, kids and other helpers pick up trash. They’ll burn plastic bags and chip wrappers into eco-bricks. Each classroom takes about 3,500 eco-bricks to build. That’s around one ton of trash!
To make eco-bricks, the kids stuff empty plastic bags and chip wrappers into cleaned plastic bottles. They need about 80 plastic bags or around 100 chip wrappers to fill one bottle all the way to the top.
Helpers from the community build frames for the classroom walls. They add chicken wire to hold the eco-bricks.
The eco-bricks are tied in rows between the layers of chicken wire. Any gaps are filled with more plastic bags.
Rows and rows of eco-bricks make up the walls. They are just as strong and last as long as other kinds of walls.
18．How are the classrooms in Guatemala and EI Salvador built differently
19．What are the materials used to build the bottle schools
20．How many eco-bricks are needed to build one classroom
21．How are the eco-bricks made
22．Are the walls made of eco-bricks as strong as other kinds of walls

Remya is living in a small village in India. Her mother suddenly became ill and her father would have to spend his time caring for her. She and her twin sister had to do most of the housework. Because the poor family couldn’t afford an electric washing machine, the two girls would have to wash the clothes by hand in the local river.
Remya wanted to make a washing machine which could be used without electricity. She started studying electric washers to learn how they worked. Remya then designed a machine that used bicycle pedals (踏板) and chain. To find those items, she and her father went to a local auto shop. Workers there not only gave her the parts, but also helped her make the machine!
Here’s how the machine works: Remya used a cylinder (圆筒) to hold the clothes and put it in a cube (立方体). Next, she connected the bicycle pedals and the chain to the cylinder. As Remya pushed the pedals with her legs, the cylinder cleaned the clothes just like a regular washing machine.
Remya’s invention worked! She had created her own human-powered washing machine—and now a task that used to take several hours took only 30 minutes, which saves time and money for the poor people in the whole world. Remya’s washing machine was chosen from among 25,000 entries as India’s best innovation (创新)! She was given India’s National Award and honored by the nation’s former president.
32．Why would Remya’s father have to care for her mother (no more than 6 words)
33．How would Remya and her sister wash the clothes at first (no more than 13 words)

Glasses are one of the most important inventions in human history. They help people with eye problems to see clearly. However, it took a long time for glasses to grow into the form we know today.
The idea of using glass to see clearly was likely first suggested by a 10th-century Arab scientist. His idea, though, wasn’t put into practice until 300 years later. Italian monks in the 13th century developed glass that made letters look larger when placed before them.
The next important development came from glass makers near Venice. They placed two lenses (镜片) in wooden rings and connected the rings together. Over time, glasses were made with different designs. But the most meaningful improvement came in the 18th century with the creation of glasses with temples and a nose bridge. These glasses rested on one’s face and were much more comfortable and convenient to use. They also act just as much as a fashion. Different styles have appeared in modern times, giving people the ability to express a different look. 眼镜还可以被用来保护我们的眼睛，像太阳镜。They protect our eyes from blinding light of the sun. Amazingly, there are glasses which help blind people see nowadays! These special glasses use smart cameras that send pictures to screens. They can even give blind people better vision (视力) than others around them, as users can control the color, brightness, and size of the images (影像) they see.
Why wear sunglasses ☆Sunglasses could prevent 98 to 99% of UV rays. ☆Polarized sunglasses (偏光太阳镜) make people see clearly. ☆Polarized lenses should be replaced (替换) every or two years. ☆About 40% of people wear sunglasses in the U.S. for health reasons. ☆Polarized sunglasses are popular for hunting, fishing, golfing, and driving.
From reading stones to modern-day medical glasses, the history of glasses has been a long and interesting one. What’s more, it is clear that our need for them will never disappear.
37．Please translate the underlined sentence in Paragraph 1 into Chinese.
38．Who first put glasses into practice in history
39．Please translate the underlined sentence Paragraph 3 into English.
40．What were created in the 18th century
41．According to the passage, how do glasses help blind people see better
42．Would you like to wear a pair of glasses Why or why not

Hungry, but in a hurry Let this robot make a pizza for you.
A French company called EKIM built the robot. It makes pizzas like a real cook. Making a pizza takes 4 minutes and 30 seconds. But the robot has three arms and can make several pizzas at the same time.
People can order their pizzas on a touch screen menu. They can choose from all kinds of pizzas.
The idea comes from two EKIM engineers. When they were students, they only had enough money for low-quality (低质量的) fast food. They grew tired of eating it.
“People today have less and less time to eat. They have to choose between time and food quality. What we’re doing is to give both.” said Philippe Goldman, CEO of EKIM.
The robot is now in a showroom. But it won’t stay there for long. The company is looking for a place in Paris to start a restaurant. The robot will be the pizza cook there!

There have been many great inventions for things that changed the way we live. The first great invention was the one that is still very important today—the wheel. This made it easier to carry heavy things and to travel to a far place. For hundreds of years after that, there were few inventions that had as much influence as the wheel.
In the second half of the 19th century, many great inventions were made. Among them were the camera, the light and the radio. These all play a big part in our daily life today.
In the first part of the 20th century, there were many valuable inventions, such as the helicopter (直升飞机) in 1909, movies with sound in 1926, the computer in 1928, jet planes (喷气式飞机) in 1930. This was also a time when a new material was first invented. Nylon (尼龙) came out in 1935. It changed the kind of clothes people wore.
The middle part of the 20th century brought new ways to help people get over illnesses. These new ways could allow people to live longer. By the 1960s, most people could expect to live to be at least 60.
New inventions will some day allow us to do things we have never dreamed of.

As we know, we all need clothes. There are all kinds of clothes to satisfy people’s needs. So “smart clothes” came into being.
“Smart clothes” are used not only for covering your bodies, but for many other kinds of uses. A German clothing maker has invented the “MP3 blue jacket”. This kind of jacket can be used as both an MP3 player and a mobile phone. An English company has developed a cloth keyboard that can be put onto your pants. You can control your computer with it easily anywhere. If it gets dirty, the keyboard can be washed and even ironed (熨).
With the technology improving, smart clothes will get much smarter. Inventors are developing clothes that can show your body temperature and heat you up before you feel cold. Other smart clothes to wear are special medical ones. They can tell the doctor when you are in danger. Shirts can warn you of high pollution levels. This technology can also provide important information about your environment. Jackets with GPS (全球定位系统) technology can keep you from getting lost.
People have begun to love the idea. Maybe smart clothes will be common in our life one day.

Jack is a businessman. His main task is to sell “Living Machines”. He is very interested in clean water. He is also interested in saving money. So it’s natural that he is to be a developer of a small and affordable system (系统) to clean waste water. His “Living Machine” can clean waste water in your home.
The “Living Machine” is a system for cleaning waste water. The waste water goes into a big plastic tank where bacteria (细菌) start to break down the waste. A few days later after it is dealt with, the water is brought into a greenhouse filled with plants and fish. With the help of sunlight, the plants and animals remove more chemicals from the water, making it cleaner. Then the water can be reused for washing or bathing. It can’t be used for drinking and cooking. But the water is clean enough for watering the flowers, washing the dog, or even for bathing or swimming.
The advantage of this technology is that it is affordable and good for the environment. If you have enough homes and businesses use “Living Machines”, you’d better buy it. It can help to use less fresh water. It can help keep the water supply unpolluted, too.
91．Is the “Living Machine” too expensive for people to buy
92．What is this “Living Machine” used for
93．How does the “Living Machine” work
94．Do you think Jack’s invention is perfect Why or why not

Do you think children who lived a thousand years ago had toys Believe it or not, they did! Their toys were very simple compared to the toys that you play with every day. Their toys were made by hand. ①The toys were made of some things. They were found in nature, like stones, wood or clay.
Children played with a few kinds of toys through the 1600s. During the 1700s, scientists began to discover and invent more materials to make toys.②They could not only use stones, wood and clay, but also use cotton, leather and paper.
Hand-carved wooden toys were popular with children through the early part of the 1800s. At that time, ③制作一个玩具花了两周时间 by hand. As a result, only a small number of them could be sold at a time and they were expensive. Toy makers looked for ways to make toys affordable for all children to enjoy.
The invention of machines changed how things were made in the 1800s, especially toys. They helped to make toys faster than by hand and in larger numbers, so toys could be more affordable. Machine-made toys were very popular among toy makers and children because they could be shaped and cut to look like real-life things.
④Thanks to the hard work by scientists, toys today are made of stronger and safer materials. Although many toys are still made of wood, metals and plastics, there are strict rules on how they can be used in toys.
