Of the 7 billion people on Earth, roughly 6 billion own a cellphone, which is pretty shocking, given that only 4.5 billion have access to a working toilet.
So how are cellphones changing us On average, people spend 4.7 hours a day looking at their bined with the length of time spent in front of computers, this has led to an increase in the nearsightedness. In North America, in the 1970s about 1/4 of the population had nearsightedness, where today nearly half do; and in some parts of Asia, 80 — 90% of the population is now nearsighted.
And it can be hard to put your phone down, take for example the game Candy Crush. As you play the game, you achieve small goals causing your brain to be rewarded with little bursts of dopamine, and eventually, you are rewarded with new contents of the game. This novelty also gives little bursts of dopamine, and they together create what is known as a “compulsion loop”, which just happens to be the same loop responsible for the behavior associated with nicotine or cocaine. According to a recent study, 93% of young people aged 18—29 report using their smartphones to avoid boredom. Without their phones, they may suffer “nomophobia”—the fear or anxiety of being without their phones.
Your smartphone can also disrupt your sleep! The screen produces a blue light which has been shown to change our biological clock, reducing the time spent in deep sleep, which is linked to the development of diabetes, cancer, and obesity.
Of course, smartphones also completely change our ability to access information, most notably in poor and minority populations. 7% of Americans are entirely dependent on smartphones for their access to the Internet.
So while phones are in no way totally bad, and have been a part of positive change in the world, there’s no denying that they are changing us.

Today, men have reached the top of the world’s highest mountains. But for many years, even people who lived among the mountains did not climb them. Indeed, people believed that men could not climb mountains.
For a long time, mountains were thought to be the home of bad spirits. People believed dragons lived on the mountainside. They thought these dragons would gobble up anyone coming near.
When men began to climb mountains, they faced many dangers. The air high on a mountain was freezing cold. There were deep cracks(裂缝) into which a climber could fall. Roaring winds and terrible storms could sweep a man off the mountainside.
At first, men did not have the proper equipment to climb high mountains. They did not have ice axes, ropes or the right kind of clothing.
Later, men could not reach the top of the highest peaks for another reason. As a man climbed higher, the air became thinner. There was less oxygen to breathe above 18, 000 feet, a climber had to stop every few steps to catch his breath. His heart beat faster and his blood became thick. Above 25, 000 feet, a climber would begin to see things that were not here. He could no longer think clearly about what he had to do.
5．This passage mainly tells us about _______.
A．the dangers of climbing high mountains
B．the bad spirits and dragons that live on the mountainside
C．the proper equipment needed to climb mountains
D．people who live in mountains
6．In this passage the underlined words “gobble up” probably means _______.
A．be fond of B．catch up with C．get hold of D．eat up very fast
7．Which of the following is true
A．The higher one climbs, the less oxygen he will breathe.
B．The main reason why people couldn’t reach the top of the mountains is that they didn’t have proper equipment.
C．The faster one climbs, the less oxygen he will need.
D．Fast beating hearts need thick blood.
Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour’s flight one of the scientists wrote in his book, “Look here for probable metal.” Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, “Gold possible.” Walking across hilly ground, four scientists reported, “This ground should be searched for metal.” From an airplane over a hilly wasteland a scientist sent back by radio one word: “Uranium(铀).”
None of the scientists had X-ray eyes: they had no magic power of looking down below the earth’s surface. They were merely putting to use one of the newest methods of locating minerals in the ground…trees and plants as signs that certain minerals may lie beneath the ground on which the trees and plants are growing.
This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow in the surface.
At Watson Bar Greek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.
Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunks had more gold than those growing on the ends of the branches.

D．A New Method of Searching for Minerals — Using Trees and Plants
Reading can be a social activity. Think of the people who belong to book groups. They choose books to read and then meet to discuss them. Now, the website turns the page on the traditional idea of a book group.
Members go on the site and register the books they own and would like to share. BookCrossing provides an identification number to stick inside the book. Then the person leaves it in a public place, hoping that the book will have an adventure, traveling far and wide with each new reader who finds it.
Bruce Pederson, the managing director of BookCrossing, says, “The two things that change your life are the people you meet and books you read. BookCrossing combines both.”
Members leave books on park benches and buses, in train stations and coffee shops. Whoever finds their book will go to the site and record where they found it.
People who find a book can also leave a joural entry describing what they thought of it. E-mails are then sent to the BookCrossing to keep them updated about where their books have been found. Bruce Pederson says the idea is for people not to be selfish by keeping a book to gather dust on a shelf at home.
BookCrossing is part of a trend among people who want to get back to the real and not the virtual (虚拟). The site now has more than one million members in more than one hundred thirty-five countries.

Predatory (捕食类的) insects benefit greatly from flowers and can even survive for long periods of time on nectar (花蜜) and pollen (花粉) alone, according to a new study. Farmers can promote a production of natural enemies to defeat pests (害虫) by planting flowers near crops in their fields.
“Pollen and nectar are things that beneficial insects can survive on when pests aren't around. By planting a wide variety of flowers both early and late in the season, one can ensure a good effect that ensures the survival of predators throughout the growing season,” says Lene Sigsgaard, professor of the plant and environmental sciences department at the University of Copenhagen. This is good news for the green transition, as effective pest control can help reduce the use of agricultural pesticides. Besides, the presence of more flowers improves pollination and biodiversity, as they attract more insects and pollinators into fields.”
In order for predatory Insects to approach flower nectar, easily approachable open flowers need to be planted, as predatory insects aren't equipped with the long feeding tubes that bees have, the researchers say. Food from flowers boosts energy for predators. Specifically, the researchers found that across all predatory insects, females survive 2.2 times longer getting access to flowers, and males 1. 7 times longer, compared to insects that only have access to water.
“It pays to design tomorrow’s agriculture so as to plant wild flowering plants alongside fields. For the greatest impact, we are looking at how to design flowering fields that benefit both predatory insects and pollinators. This will reduce the need for other forms of pest control while supporting biodiversity.” Lene says. The researchers recommend native, continuous flowers to create habitats for predatory insects, places where they can winter as well. It is also important to have a wide variety of species that produce flowers during different seasons and benefit different insects.
16．Why did the researchers suggest planting flowers next to crops
A．To help crops grow faster B．To make flowers grow stronger.
C．To make full use of natural resources. D．To ensure the supply of predatory insects.
17．What can we learn about predatory insects in Paragraph 3
A．They mainly feed on nectar. B．They have difficulty getting energy.
C．They can live longer feeding on flowers. D．They can get access to any flowers easily.
18．What is implied in Lene’s words in the last paragraph
A．Designing flowering fields properly has significant influence.
B．Maintaining biodiversity is important to agriculture.
C．It is beneficial to create various habitats for insects.
D．It is necessary to have good pest control.
19．What does the text mainly talk about
A．A way to improve biodiversity.
B．A way to grow flowers fast and well.
C．A way to protect crops against pests in fields.
D．A way to increase agricultural production quickly.
Scientists in Germany say they have used new technology to create see-through human organs (器官). They say the technology could lead to production of three-dimensional (3D) body parts for use in transplant (移植) operations.
The scientists are with Ludwig Maximilians University in Munich. They said they developed a process that uses a substance to make see- through organs, such as the brain and kidneys. The German researchers use lasers (激光) to obtain a picture of the organ to be replaced. The laser light helps them see every single cell inside the blood vessels (血管中的细胞).
The researchers use this information to print out the structure of the whole organ. For this, they need special equipment. They use a 3D printer to produce the structure--one that has height, width and length.
The researchers then load the printer with stem cells, which can become any kind of cell in the body. The stem cells act as “ink” in the printer. They are put into the correct position, making the organ fully operational.
The leader of the study, Ali Erturk, described the new technology as a major development for 3D printing in the medical field.” Previously 3D-printed organs lacked detailed cellular structures because they were based on pictures from computer tomography or MRI machines,” he explained.
“We can see where every single cell is, and we can actually replicate it exactly the same,” Erturk said. “I believe we are much closer to a real human organ for the first time now,” he added. Erturk and his team plan to start by creating bioprinted organs. They hope to develop a human kidney within 5-6 years. The researchers will first test to see if animals can live with bioprinted organs and could start tests within five to ten years, he predicted.
20．Why do the scientists need to obtain an image of the organ to be replaced
A．To copy a new one. B．To cure some diseases.
C．To observe cells in it. D．To study its structure.
21．What is the function of stem cells in making human organs
A．Matching the special equipment. B．Connecting the organs to the body.
C．Improving the quality of man-made organs. D．Filling the structures to let the organs work.
22．What was Erturk’s attitude to the new technology of creating organs
A．He threw doubt on it. B．He sang high praise for it.
C．He didn’t think much of it. D．He expressed concern about it.
23．What does the underlined word “replicate” in the last paragraph mean
A．Study. B．Copy. C．Replace. D．Remove.
“Dreams may be more important than sleep. We all need dreams,” some scientists say. Dreams take up about one quarter of our sleeping time. People have a few dreams each night. Dreams are like short films. They are usually in color. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is thinking about something. Dreaming may be a way of trying to find an answer.
Some people get new ideas about their work from dreams. They may think about their work all day. These ideas can carry over into dreams. Sometimes we wake up with a good feeling from a dream. But often we can not remember the dream. Dreams can go away quickly.
Too much dreaming cannot be good. The more we sleep, the longer we dream. The mind is hard at work when we dream. That is why we may have a long sleep and still wake up tired.

27．Which of the following is NOT true
A．Dreams may be helpful to people sometimes.
B．Too much dreaming may be bad for people.
C．People always remember their dreams quickly.
D．People sometimes wake up tired if they have a lot of dreams while sleeping.
28．The story mainly tells us___________.
A．what dreams are B．people like sleep
C．dreams are like films. D．we always remember dreams
In nature, you may see many insects and animals of different colors. Have you ever wondered why locusts are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops. When crops are young, locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.
Brown bears, tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive, they have to hide themselves in the daytime and appear only at night.
Have you ever noticed some even stranger acts The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over, its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

A．do not live in a dark and wet environment
B．do not have bright colors
C．change their colors with the soil
D．eat colorful insects like butterflies and bees
A picture may be worth a thousand words, but thanks to an artificial intelligence program called DALL-E 2, you can have a professional-looking image with far fewer.
Open Al researchers built DALL-E 2 from an enormous collection of images with captions. They gathered some of the images online and licensed others. Using DALL-E2 looks a lot like searching for an image on the web: you type in a short phrase into a text box, and it gives back six images.
But instead of selecting pictures from the web, the program creates six brand-new images, each of which reflects some version of the entered phrase. Nearly all of them could probably pass for professional photographs or drawings.
It’s easy to imagine this tool transforming the way people make images and communicate, whether via memes, greeting cards, advertising – and, yes, art.
You might say there’s little artistic merit in an image produced by a few keystrokes. But this line of thinking echoes the classic take that photography cannot be art because a machine did all the work. Today the human authorship and craft involved in artistic photography are recognized, and critics understand that the best photography involves much more than just pushing a button.
Some artists, like Ryan Murdoch, have advocated for prompt-based (基于提示的) image-making to be recognized as art. ‘They argue that the art, in using a system like DALL-E 2, comes not just from the final text prompt, but in the entire creative process that led to that prompt. Different artists will follow different processes and end up with different results that reflect their own approaches and skills.
It’s too early to judge the significance of this art form. The first films by the Lumiere brothers in the1890s were novelties, not cinematic masterpieces; it amazed people to see images moving at all.
Al art software develops so quickly that there’s continual technical and artistic novelty. It seems as if, each year, there’s an opportunity to explore an exciting new technology – each more powerful than the last, and each seemingly ready to transform art and society.
32．What can DALL-E 2 do for you
A．It edits your photographs.
B．It reproduces your paintings.
C．It collects images from the web.
D．It turns your words into pictures.
33．Why does the author mention photography in Paragraph 5
A．To explain a rule. B．To illustrate a point.
C．To present a finding. D．To define a concept.
34．What does the author think of Al art software
A．lt is promising. B．It is risky. C．It is unreliable. D．It is superior.
35．What is a suitable title for the text
A．DALL-E 2 Has Arrived. Are Artists in Trouble
B．DALL-E 2:What Exactly Is“ AI-generated Art”
C．DALL-E 2 Can Produce an Incredible Image ---- But Is It Art

细节理解题。根据第一段关键句“Have you ever wondered why locusts are super delicious food for birds, but it is not always an easy job for birds to catch them. It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops.”（你有没有想过为什么蝗虫是鸟类的超级美味食物，但鸟类捕捉蝗虫并不总是一件容易的事。这既不是因为蝗虫擅长跳跃或奔跑，也不是因为它们比敌人更聪明。原因是蝗虫的颜色随着作物的颜色而变化。）可知，对于鸟类来说，捕捉蝗虫并不总是一件容易的事，原因是蝗虫的颜色随着作物的颜色而变化，由此可知，鸟类不容易捕捉蝗虫，因为蝗虫可以改变颜色。故选D项。

32．
细节理解题。根据第二段最后一句“Using DALL-E2 looks a lot like searching for an image on the web: you type in a short phrase into a text box, and it gives back six images.(使用DALL-E2看起来很像在网上搜索图像：您在文本框中输入一个简短的短语，它会返回6张图像。)”可知，用户输入短语，软件即可生成图像。故选D。
33．
推理判断题。根据第五段“You might say there’s little artistic merit in an image produced by a few keystrokes. But this line of thinking echoes the classic take that photography cannot be art because a machine did all the work. Today the human authorship and craft involved in artistic photography are recognized, and critics understand that the best photography involves much more than just pushing a button.(你可能说敲几下键盘生成的图像没多少艺术价值。但是这种观点附和了“摄影不是艺术因为所有工作都是机器做的”这个典型看法。今天艺术摄影中人的创作和工艺已经得到认可，评论家们理解最佳摄影需要的不仅仅只是摁下快门。)”可推断，作者提到摄影是想阐述 AI 生成图像还是有艺术价值的观点。故选B。
