A
Modern inventions make our life easier and more interesting than before. Let’s take a look at some inventions.
A new kind of enzyme(酶) Scientists in Britain and the United States have found a new kind of enzyme that eats plastics. With its help, plastics can be turned into smaller parts and go away quickly. It can stop plastics from being burned everywhere. Scientists believe that it can solve the problem of plastic pollution in the future.
Social robot Can robots talk to us like humans Jibo, a robot made in US, can talk with you. The robot has a big, round head and a big body with no eyes or mouth. It uses animated icons (动画图标) to show emotions(情绪). It just seems like a real human. Right now, Jibo can only do some easy things, like taking photos and reading news to you. But it may learn to do new things in the future.
Spark Spark is a new drone(无人驾驶飞机) made by a Chinese company in Shenzhen. It can help people take photos and videos. Spark might be the smallest drone ever made. When folded, it is as small as a Coke can. The coolest part is that users can control the small drone just by using hand gestures. For example, if you wave your hand from left to right, the drone will fly in the same way. When you want it to land you just put your hand out. The drone will come to you and land on your hand.

How has technology changed our lives for the better TIME will tell you! The magazine has picked its 100 best inventions of 2021. Here we present you some of the most creative examples.
The Learning Passport
Many schools have closed their doors since the COVID-19 pandemic (新冠疫情) broke out. Home school has been difficult for some students because of slow internet service. To make matters worse, some students don’t even have an internet connection at home. The Learning Passport has a solution. The project offers browser-or-app-based (基于浏览器或手机应用的) classes. These classes do not require a consistent (持续的) internet connection. Instead, students download their lessons when there is internet connection. They can then complete the lessons later, offline.
Blue Jeans Go Green
Jeans are a fashion favorite. Every year more than 4. 5 billion pairs are sold around the world. But the production of jeans is harmful to the environment. To color them, factories use synthetic indigo dye (合成靛青染料). During the process, the chemicals in the dye cause water to become polluted. Bio-technology company Huue has created bacteria (细菌) that can turn natural sugars into indigo dye—without having any negative environmental impacts.
Battery Swapping for EVs
Electric-vehicles(EV) are popular these days. However, they still face a major problem: They can take several hours to charge (充电). This is inconvenient for many drivers. One answer to this problem lies in battery-swapping (电池替换). When an EV pulls into one of these battery-swapping stations, its depleted (耗尽的) battery is removed, and a full charged one replaces it. American company Ample has designed a universal battery. It works with all types of EVs.
31. The Learning Passport is ________.
A. a travel website B. an offline class C. a learning app D. a new kind of school
32. When people make jeans, it harms the environment by ________.
A. producing polluted air in the sky B. creating bacteria during the process
C. turning natural sugars into indigo dye D. causing water pollution during the process
33. What is the disadvantage of Electric-vehicles
A. It takes a long time to charge. B. The battery costs a lot of money.
C. There are few stations to charge. D. The battery runs out too quickly.
34. It can be inferred from the second paragraph that ________.
A. the Learning Passport is not popular B. students can’t afford to buy smart phones
C. students are not allowed to download lessons D. the pandemic has influenced the teaching methods
35. The main idea of the passage is ________.
A. to introduce some new inventions B. to advise people to save our earth
C. to encourage readers to buy more EVs D. to warn people to fight against COVID-9
C
Once upon a time, people could not write and they had no books. But they had stories.
The ancient Egyptians wrote their stories on flat sheets made from papyrus (纸莎草) plants. They glued many papyrus sheets together to make one long strip (条). Then they rolled the strip around a stick to make a scroll. People in other areas also used parchment (羊皮纸) instead.
In ancient China, books looked a little different. People there first carved (雕刻) words into bone or tortoise shell (龟壳). Later they used ink to write on strips of bamboo or silk. Then the Chinese invented (发明) paper. The first paper was made from waste cloth, but later plant materials were also used. The invention spread slowly across the world, reaching Europe in the 1100s. Then people used paper to make early books.
But all these early books still had one big problem. Every single book had to be copied out by hand. If there were pictures, each page had to be painted by hand, one at a time. This made books rare and expensive — though also very beautiful.
The Chinese were the first to think of a way to speed things up a little. In 1040, a man named Bi Sheng invented movable type printing (活字印刷). Movable type worked by carving a single Chinese word on a block of wood or clay. These could then be together with other words to create sentences, or whole pages.
In the 1400s Johannes Gutenberg of Germany invented a new way of printing. It used movable type — metal letters that could be arranged (排列) and rearranged to form words. It also used a machine called a press. Gutenberg’s inventions made printing became faster and easier.
As more books became easy to get, more people learnt to read. In the past, books were a luxury only the rich could buy. But with the printing press, they soon became a treasure everyone could enjoy.
36. What did the ancient Chinese first use as paper
A. Papyrus sheets. B. Parchment.
C. Bone or tortoise shell. D. Strips of bamboo or silk.
37. Why were early books rare and expensive
A. Because the invention of paper spread slowly across the world.
B. Because every book including pictures had to be copied out by hand.
C. Because ancient people didn’t have enough money to buy books.
D. Because people in ancient Europe didn’t invent paper like the Chinese.
38. Who invented the machine called a press
A. The ancient Egyptians. B. The ancient Chinese.
C. Bi Sheng. D. Johannes Gutenberg.
39. What’s the meaning of the underlined word “luxury”
A. something old B. something new
C. something expensive D. something cheap
40. What’s the main idea of Paragraph 5
A. The invention of parchment. B. The invention of paper.
C. The invention of movable type printing. D. The invention of Chinese words.
D
Imagine using your coat to look through the internet, send and receive messages, and even read a map. Yes, you read that correctly—your coat.
It may sound silly, but it’s something scientists are working on. Researchers at Shanghai’s Fudan University have made a new type of cloth that can be used as a digital display （显示屏）.
Professor Peng Huisheng and his team have spent 10 years trying to make “digital cloth”. After testing different combinations, they chose two materials that worked: a silver-plated yarn （镀银纱）that can light up and a kind of thread （纺线）that conducts （传导）electricity.
The results have been admirable. It’s not only wearable and foldable, but also washable. After being put through 100 wash-and-dry cycles in a washing machine and folded 10, 000 times, the cloth remained almost unchanged.
Peng believes that the new cloth could be used for many things. For example, it could allow a driver to view a GPS map on their arm while they drive around. It could also help people communicate better if they have language barriers （障碍）or disabilities.
In one test, Peng’s team collected brainwaves from volunteers who had either been playing a game or meditating. The waves were then translated into messages like “anxious” or “relaxed” and shown on the cloth. This could help deaf-mute （聋哑的） people “talk” to each other in the future.
“We hope that new materials will shape next-generation electronic devices by changing the way we interact with them, ”said Peng.
41. The researchers have made a new type of cloth that can be used as a ________.
A. digital camera B. digital display
C. digital method D. digital communication
42. A silver-plated yam and a kind of ________ were chosen to make “digital cloth”.
A. gold B. metal C. steel D. thread
43. The new cloth can allow a driver ________ on their arm when they drive around.
A. to read a GPS map B. to print a GPS map
C. to make a GPS map D. to draw a GPS map
44. The underlined word “meditating” in Paragraph 6 means ________ in Chinese.
A. 争吵 B. 打架 C. 冥想 D. 讨论
45. Which of the following statements is NOT TRUE
A. The new cloth remained unchanged after it is washed or folded.
B. New materials may shape next-generation electronic devices.
C. The new cloth could help people who have language barriers or disabilities communicate better.
D. The “fueling” shown on the cloth couldn’t help deaf-mute people “talk” to each other.

How has technology changed our lives for the better TIME will tell you! The magazine has picked its 100 best inventions of 2021. Here we present you some of the most creative examples.
The Learning Passport
Many schools have closed their doors since the COVID-19 pandemic (新冠疫情) broke out. Home school has been difficult for some students because of slow internet service. To make matters worse, some students don’t even have an internet connection at home. The Learning Passport has a solution. The project offers browser-or-app-based (基于浏览器或手机应用的) classes. These classes do not require a consistent (持续的) internet connection. Instead, students download their lessons when there is internet connection. They can then complete the lessons later, offline.
Blue Jeans Go Green
Jeans are a fashion favorite. Every year more than 4. 5 billion pairs are sold around the world. But the production of jeans is harmful to the environment. To color them, factories use synthetic indigo dye (合成靛青染料). During the process, the chemicals in the dye cause water to become polluted. Bio-technology company Huue has created bacteria (细菌) that can turn natural sugars into indigo dye—without having any negative environmental impacts.
Battery Swapping for EVs
Electric-vehicles(EV) are popular these days. However, they still face a major problem: They can take several hours to charge (充电). This is inconvenient for many drivers. One answer to this problem lies in battery-swapping (电池替换). When an EV pulls into one of these battery-swapping stations, its depleted (耗尽的) battery is removed, and a full charged one replaces it. American company Ample has designed a universal battery. It works with all types of EVs.
31. The Learning Passport is ________.
A. a travel website B. an offline class C. a learning app D. a new kind of school
32. When people make jeans, it harms the environment by ________.

C
Once upon a time, people could not write and they had no books. But they had stories.
The ancient Egyptians wrote their stories on flat sheets made from papyrus (纸莎草) plants. They glued many papyrus sheets together to make one long strip (条). Then they rolled the strip around a stick to make a scroll. People in other areas also used parchment (羊皮纸) instead.
In ancient China, books looked a little different. People there first carved (雕刻) words into bone or tortoise shell (龟壳). Later they used ink to write on strips of bamboo or silk. Then the Chinese invented (发明) paper. The first paper was made from waste cloth, but later plant materials were also used. The invention spread slowly across the world, reaching Europe in the 1100s. Then people used paper to make early books.
But all these early books still had one big problem. Every single book had to be copied out by hand. If there were pictures, each page had to be painted by hand, one at a time. This made books rare and expensive — though also very beautiful.
The Chinese were the first to think of a way to speed things up a little. In 1040, a man named Bi Sheng invented movable type printing (活字印刷). Movable type worked by carving a single Chinese word on a block of wood or clay. These could then be together with other words to create sentences, or whole pages.
In the 1400s Johannes Gutenberg of Germany invented a new way of printing. It used movable type — metal letters that could be arranged (排列) and rearranged to form words. It also used a machine called a press. Gutenberg’s inventions made printing became faster and easier.
As more books became easy to get, more people learnt to read. In the past, books were a luxury only the rich could buy. But with the printing press, they soon became a treasure everyone could enjoy.
36. What did the ancient Chinese first use as paper
A. Papyrus sheets. B. Parchment.
C. Bone or tortoise shell. D. Strips of bamboo or silk.
37. Why were early books rare and expensive
A. Because the invention of paper spread slowly across the world.
B. Because every book including pictures had to be copied out by hand.
C. Because ancient people didn’t have enough money to buy books.
D. Because people in ancient Europe didn’t invent paper like the Chinese.
38. Who invented the machine called a press
A. The ancient Egyptians. B. The ancient Chinese.
C. Bi Sheng. D. Johannes Gutenberg.
39. What’s the meaning of the underlined word “luxury”
A. something old B. something new
C. something expensive D. something cheap
40. What’s the main idea of Paragraph 5
A. The invention of parchment. B. The invention of paper.
C. The invention of movable type printing. D. The invention of Chinese words.

Imagine using your coat to look through the internet, send and receive messages, and even read a map. Yes, you read that correctly—your coat.
It may sound silly, but it’s something scientists are working on. Researchers at Shanghai’s Fudan University have made a new type of cloth that can be used as a digital display （显示屏）.
Professor Peng Huisheng and his team have spent 10 years trying to make “digital cloth”. After testing different combinations, they chose two materials that worked: a silver-plated yarn （镀银纱）that can light up and a kind of thread （纺线）that conducts （传导）electricity.
The results have been admirable. It’s not only wearable and foldable, but also washable. After being put through 100 wash-and-dry cycles in a washing machine and folded 10, 000 times, the cloth remained almost unchanged.
Peng believes that the new cloth could be used for many things. For example, it could allow a driver to view a GPS map on their arm while they drive around. It could also help people communicate better if they have language barriers （障碍）or disabilities.
In one test, Peng’s team collected brainwaves from volunteers who had either been playing a game or meditating. The waves were then translated into messages like “anxious” or “relaxed” and shown on the cloth. This could help deaf-mute （聋哑的） people “talk” to each other in the future.
“We hope that new materials will shape next-generation electronic devices by changing the way we interact with them, ”said Peng.
41. The researchers have made a new type of cloth that can be used as a ________.

C. to make a GPS map D. to draw a GPS map
44. The underlined word “meditating” in Paragraph 6 means ________ in Chinese.
A. 争吵 B. 打架 C. 冥想 D. 讨论
45. Which of the following statements is NOT TRUE
A. The new cloth remained unchanged after it is washed or folded.
B. New materials may shape next-generation electronic devices.
C. The new cloth could help people who have language barriers or disabilities communicate better.
D. The “fueling” shown on the cloth couldn’t help deaf-mute people “talk” to each other.
