But farming takes up a lot of land and water. Scientists are now looking for new ways to grow food. One of them is vertical farming (垂直农业). In vertical farming, plants are grown inside buildings, in layers (层) one on top of another. This saves a lot of space. Vertical farms use special lights to help plants grow. They don’t need soil. Instead, they use water with nutrients (营养物). This is called hydroponics (水培法). Because the plants are inside, they are not affected by bad weather. Also, fewer pests (害虫) can reach them, so farmers don’t need to use many pesticides (杀虫剂).Many people think vertical farming is a good idea. It can produce food near cities, so the food doesn’t have to travel far. This saves energy and keeps the food fresh. However, building a vertical farm is very expensive. It also uses a lot of electricity for the lights. Scientists are still working to make it cheaper and better. 1.What is vertical farming? A. Growing plants on the ground.   B. Growing plants in layers inside buildings. C. Growing plants in the soil.   D. Growing plants in the open air. 2.What does the word “hydroponics” (in Paragraph 2) probably mean? A.

(二) Do you know that the air we breathe can be badly polluted? In many cities, the air is full of harmful gases and dust. This is called air pollution. It can cause many health problems, such as coughing, breathing difficulties, and even heart disease. Children and old people are more easily hurt by it.What can we do to reduce air pollution? First, we can use public transport, like buses and subways, instead of driving cars. This can cut down the amount of harmful gases from cars. Second, we should plant more trees. Trees can take in harmful gases and give out oxygen, which is good for our health. Third, we can use clean energy, such as wind and solar power (太阳能). These kinds of energy do not produce harmful gases.Many countries are now working together to fight air pollution. They have made laws to control the amount of pollution from factories. They also encourage people to live a greener life. If everyone does their part, the air can become cleaner and healthier. 6.What is the main topic of the passage? A. The causes of air pollution.   B. The problems and solutions of air pollution. C. The history of air pollution.  D. The benefits of clean energy. 7.What does the word “reduce” (in Paragraph 2) probably mean? A.

It also helps our brain to store memories and learn new things. Most adults need about 7 to 9 hours of sleep every night. But many people do not get enough sleep. This is a common problem called sleep loss (睡眠不足).What causes sleep loss? There are many reasons. Some people stay up late to work or study. Others play video games or watch TV late into the night. Stress and worry can also make it hard to fall asleep. Some people have a sleep disorder (睡眠障碍) called insomnia (失眠症), which makes it very difficult for them to sleep. Sleep loss can cause many problems. People who don’t get enough sleep may feel tired and have trouble concentrating (集中注意力). They may also get sick more easily. In the long term, sleep loss can lead to serious health problems like heart disease and obesity (肥胖). So it is important to have good sleep habits. Go to bed at a regular time, and avoid using your phone before sleeping. 11.What is the passage mainly about? A. The importance of dreams.   B. The causes and effects of sleep loss. C.

We use it to make many things, like bottles, bags, and toys. But plastic also causes a big problem. It takes a very long time to break down (分解) in nature. Some plastic can take hundreds of years to disappear. This is called plastic pollution (塑料污染). A lot of plastic waste ends up in the ocean. This is very bad for sea animals. Turtles may mistake plastic bags for jellyfish and eat them. Fish may eat small pieces of plastic. This can make them sick. When we eat fish, the plastic can also get into our bodies. So plastic pollution is a danger to all living things. What can we do to help? First, we can reduce the use of plastic. For example, we can use cloth bags instead of plastic bags. We can also use reusable water bottles. Second, we should recycle plastic. Many plastic items can be made into new things. Third, we can take part in clean-up activities to pick up plastic waste from beaches and parks. 16.What is the main problem of plastic mentioned in the passage? A. It is too expensive.   B.

In the past, robots were mostly used in factories. They could do simple jobs like lifting heavy things or putting parts together. Now, robots are becoming smarter and more common in our daily lives. There are many different kinds of robots. Some robots help clean our homes. For example, the robot vacuum cleaner can move around the house and clean the floor by itself. Some robots are used in hospitals. They can help doctors do operations (手术) more carefully. Some robots are even used to explore (探索) dangerous places, like deep under the sea or on other planets. Scientists are working on making robots that can think and learn like humans. These are called AI (人工智能) robots. They can learn from their experiences and make decisions. For example, some AI robots can play chess with people and even beat them. In the future, robots may do many more jobs. But some people worry that robots might take away jobs from humans. Scientists say we need to use robots wisely. 21.What is the passage mainly about? A. The history of robots.   B. The uses and future of robots. C. How to make a robot.   D.

Vitamins are special substances that help your body grow and work properly. There are many different kinds of vitamins. Each one has a different job. For example, vitamin A is good for your eyes. Vitamin C helps your body fight off colds and infections (感染). Where can we get vitamins? The best way is to eat a balanced diet (均衡饮食). Different foods give us different vitamins. Fruits and vegetables are rich in vitamins. Oranges, strawberries, and carrots are all good sources. Milk and eggs also contain many vitamins. Meat, fish, and beans are important for some vitamins too.If we don’t get enough vitamins, we may have health problems. For example, not having enough vitamin C can make our gums (牙龈) bleed. Not having enough vitamin D can make our bones weak. But it is also possible to get too many vitamins. Some people take vitamin pills (药片). Taking too many can be harmful. So it is best to get vitamins from food and talk to a doctor before taking any pills. 26.What is the passage mainly about? A. The history of vitamins.   B. The importance and sources of vitamins. C.

We can use it to find information, talk to friends, and do many other things. But spending too much time online can be a problem. Some people become addicted (上瘾的) to the Internet. This is called Internet addiction (网络成瘾).Internet addiction means that a person cannot control the time they spend online. They may spend hours playing games, watching videos, or scrolling (滚动) through social media. They may forget to eat, sleep, or do their homework. This can harm their studies, health, and relationships with family and friends. How can we prevent Internet addiction? First, we should set a time limit (限制) for using the Internet. For example, we can decide to only use it for one hour a day. Second, we should find other hobbies, like playing sports or reading books.

In the past, robots were mostly used in factories. They could do simple jobs like lifting heavy things or putting parts together. Now, robots are becoming smarter and more common in our daily lives. There are many different kinds of robots. Some robots help clean our homes. For example, the robot vacuum cleaner can move around the house and clean the floor by itself. Some robots are used in hospitals. They can help doctors do operations (手术) more carefully. Some robots are even used to explore (探索) dangerous places, like deep under the sea or on other planets. Scientists are working on making robots that can think and learn like humans. These are called AI (人工智能) robots. They can learn from their experiences and make decisions. For example, some AI robots can play chess with people and even beat them. In the future, robots may do many more jobs. But some people worry that robots might take away jobs from humans. Scientists say we need to use robots wisely. 21.What is the passage mainly about? A. The history of robots.   B. The uses and future of robots. C. How to make a robot.   D.
