These little symbols are not easy to be noticed, but are really important. They tell you what kind of plastic it is and whether it can be recycled or not. Can it be recycled? Types of Plastic √ PET This is the plastic that you often see on supermarket shelves! It’s used to make plastic water bottles and biscuit boxes. √ HDPE HDPE is a stronger type of plastic. It is what milk bottles are made of. × LDPE LDPE is a very soft plastic which is not easily broken. It is what shopping bags are made of. √ PS (POLYSTYRENE) This plastic is often seen in our daily lives. You’ll probably have seen it as those cheap white cups you get hot drinks in, or as takeaway food packaging. 1. Which is a stronger type of plastic? A. PET. B. HDPE. C. LDPE. D. PS. 2. What is the purpose of this article? A. To introduce types of plastic. B. To show some reusable things. C. To explain recycling methods. D. To tell the harm of plastic bags. 3. Where is the text most probably from? A. A travel guidebook. B. A geography textbook. C. A life website. D. A movie poster. B Many people are afraid of sharks, but they usually do not know much about them. For example, there are at least 350 kinds of sharks, and all of them eat meat. Some sharks are very big. The whale sharks are 9 to 14 meters long. But some sharks are very small. The spined pygmy sharks are only 18 to 28 centimeters long. Sharks have a very long history. In fact, the earliest known sharks date back to more than 420 million years ago. Today, sharks live in every ocean in the world, but most sharks live in warm water. They keep the oceans clean because they eat sick fish and animals. Most sharks have four to six rows of teeth. When a shark’s tooth falls out, another tooth moves in from behind. "________" However, they’ll "hear" sounds and movements in the water. When any sound of movement makes the water vibrate (振动), sharks can feel these vibrations, and these vibrations can help sharks find food. Sharks use their large eyes to find food, too. Most sharks can see clearly in little light. They often look for food in the dark, in the evening, or in the middle of the night. Scientists want to learn more about sharks for several reasons. For example, cancer (癌症) is common among many animals and people. However, few sharks have it. Scientists want to find out why sharks almost never get cancer. Maybe it can help people find some great ways to stop having cancer. 4. Scientists want to know most why sharks ________. A. have so many teeth B. have such a long history C. almost never get cancer D. can see best in the dark 5. Which of the following is TRUE about sharks? A. Sharks can hear sounds and movements with their ears. B. Most sharks can look for food clearly in little light with their small eyes. C. There are less than 350 kinds of sharks in the world. D. Sharks can keep the oceans clean because they eat sick fish and animals. 6. Which of the following is the best sentence to fill in the blank "________" in Paragraph 2? A. Sharks use teeth to bite things. B. Sharks do not have ears. C. Most sharks have very good eyesight. D. Scientists are interested in sharksˈ food. 7. Who might be interested in this passage? A. Mary—she likes English very much. B. Peter—he wants to swim in the sea. C. Andrew—he is interested in studying animals. D. Jane—she wants to be a policewoman when she grows up. C Have you seen new plants starting to grow? Have you noticed that the days are getting longer, with more daylight to enjoy? These are signs of spring, promising the return of light, color and warm days. Spring tells us that no matter how dark or cold things might be, better days are on the way. What is hope? "Hope is the knowledge that things can get better," says the writer Russell. When she was writing her latest book, How to Be Hopeful, Russell spoke to people who had difficult moments, such as firefighters (消防员). "The firefighter said, 'If we don't fight it, there's no chance of enjoying a new day,'" explains Russell. However, hope is also about taking action. Russell says, "If you look at history, from winning the Second World War to people traveling thousands of miles away to build a new home, there is a long history of taking action with hope." Why is hope good for you? Scientists say that having hope in difficult moments can help you worry less, feel calmer and improve your feelings. Research also shows that hope can help reduce pain. What's practical hope? Experiencing disappointment and feeling worried or sad are part of life. If it's possible to see hope in these moments, you should; if it’s not, don't worry. Dr. Williamson calls this "practical hope". "Life is a mess," says Williamson. "We don't need to always make others think you are fine, but we can realize how we feel, whether that's sadness or anger, and pay attention to the opposite. You can't change the fact that your brother or sister is bad to you, but you can do something kind and friendly instead of making things worse. Even in the most terrible situations we can decide what we do and say to each other." 8. Why does the writer talk about spring in paragraph 1? A. Because spring is very beautiful. B. Because spring brings us hope. C. Because spring is a warm season. D. Because spring has longer days. 9. What does the underlined word "it" in paragraph 2 refer to (指代)? A. The brave firefighter. B. The latest book. C. The difficult moment. D. The famous writer. 10. According to Williamson, if you are sad or angry, you should ________. A. try to be happy or calm B. try to grow more plants C. enjoy being sad or angry D. enjoy making more friends 11. What’s the writer’s purpose in writing the text? A. To show the greatness of hope. B. To tell stories of fighting for hope. C. To introduce real actions with hope. D. To encourage us to do things with hope. D ①In December 2021, people in Shenzhen found that water ran more slowly from their taps. The government said the city was facing its most serious water shortage (短缺) ever. ②Some other cities in the southern part of China, like Chengdu and Guangzhou, are also becoming "thirsty", The Paper reported. Compared (相比) with northern areas, southern areas have more rain and are close to more rivers and lakes. So why are they still short of water? ③In big cities like Shenzhen and Guangzhou, populations are growing fast. As a result, people and factories need more and more water. Each person in Shenzhen has less than 200 cubic meters (立方米) of water each year. It’s 1/12 of the country’s average (平均水平). According to the United Nations, it is an "absolute water shortage (极度缺水)" when the number is below 500 cubic meters. ④Climate (气候) change is making the water problem worse. For example, most cities in Guangdong depend on the Dongjiang River as their main source (来源) of water. In 2021, the river was reported to be drying up. Because of climate change, there’s also less snow in the mountains of Xizang. The snow has long been the source of water for many areas in China. Those mountains might provide less water in the future. ⑤There are other reasons for water shortages. For example, water pollution makes it harder to get clean drinking water. Factories and farms don’t use water in right ways. Some cities have enough rainfall, but donˈt have big lakes or reservoirs (水库) to store water. The water just goes into the sea. 12. The main purpose of the writer writing the passage is ________. A. to introduce the "absolute water shortage" B. to encourage the government to build reservoirs C. to explain why populations grow fast in big cities D. to tell the reasons for water shortages in some cities 13. According to the passage, each person in China has ________ cubic meters of water each year. A. below 200 B. below 500 C. about 2,400 D. about 6,000 14. It can be learned from the passage that ________. A. northern areas are close to more rivers and lakes than southern areas in China B. Shenzhen is facing "absolute water shortage" according to the United Nations C. neither climate change nor water pollution has something to do with water shortages D. we don’t need big lakes or reservoirs to store water because we have enough rainfall 15. Which of the following best shows the structure of the passage? A. B. C. D. 二、 根据句意和首字母写单词(每题2分，共28分) 1. Children can sometimes be very c​​​​​​​           to kill insects or little animals. 2.

The small seaside village was once home to 2, 000 people. Most of them were farmers, like Satter. But rising seas poisoned (毒化) the soil with salt water. Two major storms in the last two years destroyed the mud barriers (土坝) that protected the village from the sea. Today, only 480 people remain. “The effects of global warming are destroying parts of Bangladesh,” said Mohammad who is the head of the research center PRD. Salt in soil has increased by 26 percent over the past 35 years. In 1973, 833, 000 hectares (公顷) of land were poisoned by sea water. Areas of fresh water were also poisoned. This grew to 1. 02 million hectares in 2000, and 1. 056 million hectares in 2009, reports Bangladesh’s SRDI. At BT Village, the women walk up to 4 kilometers to a well (井) to collect water for cooking and drinking every day. Wells in the area only have fresh water in the months after yearly heavy rains. In summer, fresh water is difficult to find, said one of the women, Halder. The villages lie in Bangladeshˈs southwestern Shyamnagar area. The area is home to 400, 000 people. Officials say the government does not have the money to build desalination (脱盐) factories. “The area needs maybe 500 desalination factories. But we’ve only got 50,” said Alamgir, head of a local organization. The United Nations made a report that warned global warming would get worse in the coming years even if humans immediately stopped producing carbon gas. After the UN report, the question remains: Will world leaders choose to protect the environment? No matter what the world leaders do, there are a lot of ways individual (个体) people can make choices to protect the environment. People can change what they eat or travel without getting on an airplane, for example. Benjamin Clarysse is a bio-engineer who works with a number of environmental groups in northern Belgium. He warns, political leaders still need to promise changes. They cannot just depend on citizens (市民) doing their part. “They cannot just say that everyone should just do a little bit of the work,” Clarysse said. “Depending on just the goodwill of people won’t get you there.” 1.
