七、阅读理解
The Beijing 2022 Winter Olympics were more than a sporting event. They were also a showcase (展示) for science and technology. Let’s look at some.
A lot of different kinds of robots served visitors and athletes during the Olympics. Some machines were used to enforce social distancing requirements related to COVID-19. Robots could also transport equipment, clean surfaces, prepare and carry food to limit human-to-human contact.
The National Speed Skating Oval is said to have “the fastest ice” because 12 new Olympic records and one world record were set there. The secret is a new ice-making technology. Liquid carbon dioxide (液态二氧化碳) is put under the ice to keep temperature changes on the ice surface within half a degree. That keeps the ice flat. Flat ice is easier to skate on.
During the speed skating race, athletes can reach speeds of up to 18 meters per second. To capture (捕捉) every exciting moment of the competition, Lie Bao was used for the event. Lie Bao can record speeds of up to 25 meters per second. It closely tracks (跟踪) the athletes’ movements and captures various scenes during speed skating.
Gu Ailing got a historic gold medal at the Beijing Winter Olympics in the women’s freestyle skiing Big Air on Feb 8. She won 1 with her first 1620 — four and a half full rotations (旋转) which have been presented to people in the way of a “time slice”. The system shows the athletes’ movements from takeoff to landing in one frame (画面).
1. Lie Bao was used during ________.
A the ice hockey match B. the ski jumping event
C. the speed skating race D. the freestyle skiing event
2. ________ can show the game from the beginning to the end in one frame.
A. The robot B. The fastest ice
C. The high-speed camera D. The time slice
3. The new ice-making technology is to ________.
A. keep the ice flat
B. limit human-to-human contact
C. capture every exciting moment of the competition
D. keep the ice at the same temperature
B
Smartphones are getting boring. The new models are either a bit faster or have better cameras, but they are basically no different from the ones already in our pockets. This is why scientists are hoping, and working for something new, something that will change our lives just as greatly as smartphones do. At the moment, the next invention might be smart glasses.
Just imagine. Instead of having to pick up your phone and look at the screen, all of the information you need simply appears just in front of you, in your glasses. Satellite navigation (导航) directions would appear right there on the road. And your smart glasses could guide you to the right shelf in the supermarket!
Smart glasses could also be used in industry. They could show engineers the instructions they need to fix things more quickly. A doctor could carry out a difficult operation, guided in real time by someone on the other side of the world.
This may sounds impossible. But most of the technologies to invent them are already there. For example, one key technology is called AR, which can make digital 3D objects appear as if they are part of the real world. We’ve used it a lot on our video calls. Similarly, huge progress has been made in spatial audio. This is when a sound is made to give it a sense of place, like what you hear in an empty room. Some high-end earphones can already do that. Future glasses will of course need to recognize (识别) your voice to do tasks. This technology has been widely used in our daily life.
So, why aren’t we all wearing smart glasses yet So far, no one has invented a good way to send images (映像) of our world onto glasses. However, with the rapid development of technology, smart glasses could arrive much sooner than we think.
1. Why does the writer mention smartphones in Paragraph 1
A. To start a story. B. To explain an idea. C. To introduce a topic. D. To discuss a problem.
2. What are Paragraphs 2 and 3 mainly about
A. When smart glasses might be made.
B. Where smart glasses could be used.
C. How smart glasses would give directions.
D. Why smart glasses should be changed.
3. Which of the following technologies needs to be improved to invent smart glasses
A. Making spatial audio. B. Recognizing voices.
C. Creating digital 3D objects. D. Sending images onto glasses.
4. How might the writer feel about the future of smart glasses
A. Bored. B. Confident. C. Satisfied. D. Uncertain.

七、阅读理解
The Beijing 2022 Winter Olympics were more than a sporting event. They were also a showcase (展示) for science and technology. Let’s look at some.
A lot of different kinds of robots served visitors and athletes during the Olympics. Some machines were used to enforce social distancing requirements related to COVID-19. Robots could also transport equipment, clean surfaces, prepare and carry food to limit human-to-human contact.
The National Speed Skating Oval is said to have “the fastest ice” because 12 new Olympic records and one world record were set there. The secret is a new ice-making technology. Liquid carbon dioxide (液态二氧化碳) is put under the ice to keep temperature changes on the ice surface within half a degree. That keeps the ice flat. Flat ice is easier to skate on.
During the speed skating race, athletes can reach speeds of up to 18 meters per second. To capture (捕捉) every exciting moment of the competition, Lie Bao was used for the event. Lie Bao can record speeds of up to 25 meters per second. It closely tracks (跟踪) the athletes’ movements and captures various scenes during speed skating.
Gu Ailing got a historic gold medal at the Beijing Winter Olympics in the women’s freestyle skiing Big Air on Feb 8. She won 1 with her first 1620 — four and a half full rotations (旋转) which have been presented to people in the way of a “time slice”. The system shows the athletes’ movements from takeoff to landing in one frame (画面).
1. Lie Bao was used during ________.
A the ice hockey match B. the ski jumping event
C. the speed skating race D. the freestyle skiing event
2. ________ can show the game from the beginning to the end in one frame.
A. The robot B. The fastest ice
C. The high-speed camera D. The time slice
3. The new ice-making technology is to ________.
A. keep the ice flat
B. limit human-to-human contact
C. capture every exciting moment of the competition
D. keep the ice at the same temperature
【答案】CDA
【解析】本文主要介绍了2022年北京冬奥会对科学和技术的展示。

B
Smartphones are getting boring. The new models are either a bit faster or have better cameras, but they are basically no different from the ones already in our pockets. This is why scientists are hoping, and working for something new, something that will change our lives just as greatly as smartphones do. At the moment, the next invention might be smart glasses.
Just imagine. Instead of having to pick up your phone and look at the screen, all of the information you need simply appears just in front of you, in your glasses. Satellite navigation (导航) directions would appear right there on the road. And your smart glasses could guide you to the right shelf in the supermarket!
Smart glasses could also be used in industry. They could show engineers the instructions they need to fix things more quickly. A doctor could carry out a difficult operation, guided in real time by someone on the other side of the world.
This may sounds impossible. But most of the technologies to invent them are already there. For example, one key technology is called AR, which can make digital 3D objects appear as if they are part of the real world. We’ve used it a lot on our video calls. Similarly, huge progress has been made in spatial audio. This is when a sound is made to give it a sense of place, like what you hear in an empty room. Some high-end earphones can already do that. Future glasses will of course need to recognize (识别) your voice to do tasks. This technology has been widely used in our daily life.
So, why aren’t we all wearing smart glasses yet So far, no one has invented a good way to send images (映像) of our world onto glasses. However, with the rapid development of technology, smart glasses could arrive much sooner than we think.
1. Why does the writer mention smartphones in Paragraph 1
A. To start a story. B. To explain an idea. C. To introduce a topic. D. To discuss a problem.
2. What are Paragraphs 2 and 3 mainly about
A. When smart glasses might be made.
B. Where smart glasses could be used.
C. How smart glasses would give directions.
D. Why smart glasses should be changed.
3. Which of the following technologies needs to be improved to invent smart glasses
A. Making spatial audio. B. Recognizing voices.
C. Creating digital 3D objects. D. Sending images onto glasses.
4. How might the writer feel about the future of smart glasses
A. Bored. B. Confident. C. Satisfied. D. Uncertain.
