话题7 科技与生活

Passage 1

Every year, Time magazine puts out its list of the year’s best inventions. Some of them help us solve problems, while others make life easier or more fun. Here are three of the inventions on this year’s list. Which one do you think is the best?

Life-like animals

At the Hologram Zoo (全息动物园) in Australia, you don’t just see a giraffe. You see a group of giraffes running towards you and then over you. “We show people things they have never seen before,” says the zoo’s CEO. Visitors to the zoo can see life-like wonders. Thanks to hologram technology, the public can see wildlife while no animals have to be kept in cages.

Stopping fires

Alert Califormia is a safety program in California. It uses AI to predict wildfires. The AI detector (探测器) uses more than a thousand cameras in forests across the state. It can spot smoke and other early signs of fire. In two   months, the program correctly predicted 77 fires before any 9ll calls came in.

Air on Mars

If astronauts land on Mars in the future, they’ll need air to breathe and a way to get home. NASA’s Moxie can help solve both problems. This small equipment can separate oxygen (氧气) from the atmosphere (大气) on Mars and help astronauts breathe. In addition, the oxygen can be used to provide energy for spaceships. This is important for sending astronauts home from Mars.

1. What makes the Hologram Zoo in Australia special?

A．The high technology. B．A safety program. C．The CEO. D．A spaceship.

2. Why is NASA’s Moxie used by astronauts?

A．To predict the fires.     B．To meet the needs of breath.

C．To call the spaceship. D．To send animals home

3. Which part of a magazine in the text probably taken from?

A．History B．Business. C．Culture. D．Science.

 

Passage 2

In the past, if doctors wanted to learn about the human body, they don’t have many choices: studying from books, or doing research on animals or plants. Well, time has changed. Now, there’s something new called 3D printing, and it’s making big changes in how doctors learn.

Last year, a research team from the Lanzhou Institute of Chemical Physics at the Chinese Academy of Sciences invented hydrogel (水凝胶), a new material for 3D printing. As the “ink” for printing, hydrogel has helped the research team create 3D printed organs (器官), including the brain and heart. People found it hard to print the complex structures inside human organs before. It’s also hard to control the organs’ hardness (硬度). Luckily, this team has managed to make meaningful progress in these two aspects.  ▲ . A doctor who tried these models said that he wouldn’t know they were not real if he was not told.

On the other hand, the research team had another problem to solve. Human organs have different textures (质地). For example, our brains are the softest. The team added special material to the hydrogel to create different textures for each organ. They also printed tiny holes and channels (通道) inside the organs. This will help medical students learn better. Compared to human organs and animal organs, 3D printed organs are also cheaper and more acceptable for medical students.

Apart from doing research, scientists are also working on 3D printed organs used in organ transplants (移植). Hydrogel cannot be used because the human body will fight against it. But scientists are looking for other materials that can grow inside the human body. Currently, a bladder (膀胱) has been successfully transplanted using 3D printing because it’s one of the simplest organs. Experts expect that this technology will help more patients within a few years, according to CNN.

1. Why is 3D printing changing how doctors learn?

A．Because it allows them to practice on live animals.

B．Because it allows them to create 3D printed organs.

C．Because it allows them to study biology using their bodies.

D．Because it allows them to control the hardness of organs.

2.【信息还原】 Which sentence can be put in    ▲   ?

A．Scientists think hydrogel is not good enough.

B．The printed organs are very close to real organs.

C．The research team wants to grow new organs from old ones.

D．Doctors will use 3D printed organs on animals.

3. In which magazine can we read the passage?

A．Medical Science.        B．Local food. 

C．Traveling around the world. D．Computer science.

Passage 3

. New technology improves our lives and changes the way we do things. In 2020, we saw many new technologies come out. They are going to change our future. Let’s take a look at two of them.

Virtual patients

You may have heard that computers and robots might one day take the place of human doctors. But what if computers were used to take the place of patients? Now scientists test new medicine and treatment on virtual body parts. These virtual bodies are made by computers. Testing new

medicine or treatments on live patients can be dangerous. It also costs a lot of money. But virtual patients could change this.

Low-carbon (低碳) concrete (水泥)

Concrete is a most widely-used building material in the world. But making concrete is bad for the environment. Concrete factories put out a lot of CO2, which can make global warming worse. Solidia, a US technology company, has found a new way to make concrete. They use more clay (黏土), less limestone (石灰岩), and less heat. This cuts CO2 by 30%. Another US company, BioMason, is “growing concrete out of bacterial (细菌) and particles (微粒). This means they put out almost no CO2 at all.”

1. What is this passage probably?

A．A science report. B．A diary. C．A travel guide. D．A film.

2. What does the underlined word “virtual” probably mean?

A．Unreal. B．Young. C．Unable. D．Old.

3. Which can be the best title for the passage?

A．A Better Future B．Technology for Future

C．A Modern World D．Science at Home

Passage 4

. This year, we celebrate 30 years since China started to build its Beidou Navigation Satellite System (BDS, 北斗卫星导航系统). It took its name from the Big Dipper stars, a group of seven bright stars in the sky.

In 1994, China began building the BDS, so it wouldn’t have to use navigation systems from other countries. It’s a lot safer this way. In 2020, the BDS was completed. This achievement made China the fourth to have its own navigation system after the US, Russia and the European Union.

The BDS does not just show where you are. It’s the first to let you send messages where there is no phone signal (信号). It has also played an important role in disaster prevention and response (防灾救灾). It even helps farmers in China by providing information for planting, which makes farming smarter.

The BDS is more than a system. It shows China’s ability in science and technology. Now, over 120 countries and areas are using it. Wherever you are, the BDS is there to help you find your way.

1. Where did the BDS get its name from?

A．A country. B．A group of stars. C．A planet. D．An invention.

2. When did China begin building the BDS?

A．In 1994. B．In 2000. C．In 2020. D．In 2024.

3. What is paragraph 3 mainly about?

A．The advantages of the BDS.         B．The ways to make farming smarter.

C．The suggestions on repairing the BDS. D．The methods of preventing disasters.

4. What does the BDS show about China?

A．Its work in protecting nature.         B．Its development in education.

C．Its ability in science and technology. D．Its achievements in making phones.
