People have always been scared of sharks, but the film Jaws made things worse. It made people frightened of sharks, especially of the great white shark. Many people started to believe that sharks were bad animals that humans should fear. Some people began fishing for sharks, killing as many as they could. After 1975, the number of large sharks around America fell quickly, and soon fell around the world. This was not only due to fear of sharks, but also finning. Finning is a type of fishing where sharks are caught and their fins cut off. The sharks are thrown back into the sea where they die slowly and painfully. The fins are used to make shark fin soup. Peter Benchley, the man who wrote the book Jaws, later saw an awful sight: an area where fishermen were finning, and the sea floor was covered with dead sharks. He came to see people as a danger to sharks, rather than the other way round. From that day on, he fought to protect sharks. Experts have proved that sharks do not see people as food, and they attack us by mistake. Only around six people are killed by sharks every year. Today, as we learn more about sharks, more people than ever want to protect them from extinction. 1.What made people fear sharks greatly? A. The film Jaws. B. Shark attacks on humans. C. The overfishing of sharks. D. The spread of shark fin soup. 2.Why do people fish for sharks mainly? A. Because sharks are dangerous. B. Because they need shark fins. C. Because they want to protect sharks. D. Because they want to study sharks. 3.What happened to the number of large sharks after 1975? A. It increased. B.It doubled. C. It remained the same. D. It decreased. 4.What did Peter Benchley do later? A. He continued writing frightening stories. B. He became more afraid of sharks. C. He started to protect sharks. D. He began to fish for sharks. 5.What do experts think of shark attacks? A. Sharks attack humans for food. B. Sharks attack humans by mistake. C. Sharks never attack humans. D. Sharks attack humans on purpose. B What’s Really Green? Most of us try to save energy and reduce pollution. But recently, some “green truths” have been shown to be only half true, or even completely false. Paper shopping bags are better than plastic ones？ It’s true that plastic bags cause litter and danger to sea animals. Plastic takes hundreds of years to break down. However, making a paper bag uses four times as much energy as making a plastic bag and produces more greenhouse gases. So the best choice is a reusable bag. When you turn off a device, it stops using power？ When we turn off a television, it goes into stand-by mode. Devices in this mode still use power. To make sure your appliance is really off, unplug it. It’s better to take a shower than a bath？ It depends on how long you spend in the shower. If you spend more than eight minutes, you’ll use as much water as in a bath. The key is to keep your shower short. 6.What do some people wrongly think? A. Paper bags are always better than plastic ones. B. Plastic bags are better than paper ones. C. Both bags are bad. D. Neither bag is good. 7.How much more energy does a paper bag use? A. twice B. three times C. four times D. five times 8.What happens after you turn off a device? A. It uses no power at all. B. It produces electricity. C. It breaks down at once. D. It still uses power in stand-by mode. 9.What is the key to a green shower? A. Take a longer shower. B. Take a bath instead. C. Use a special shower head. D. Take a shorter shower. 10.What’s the main idea of the text? A. Plastic bags are harmful. B. Some “green truths” are not fully true. C. We must save water. D. Reusable bags are the best. C Six Things You Can Do to Help Stop Global Warming Global warming is a serious problem. Temperatures are rising, ice caps are melting, and extreme weather like floods and droughts is becoming more frequent. Humans are the main cause—we produce too much carbon dioxide by burning fossil fuels, cutting down trees, and wasting energy. But we can take action to change this. Here are six useful tips: 1.Use renewable energy. Walk or ride a bike instead of driving. Choose solar or wind power for your home if possible. 2.Save energy. Replace regular bulbs with LED ones to cut down CO₂ emissions. 3.Plant trees. Trees absorb CO₂ and release oxygen, helping to cool the planet. 4.Reduce waste. Use reusable water bottles and bags instead of disposable ones. Recycle paper, plastic, and glass. 5.Save water. Fix leaky taps and take shorter showers—saving water reduces the energy used in water treatment. 6.Raise awareness. Talk with friends and family about global warming. Encourage them to join in environmental protection. 11.What is the main cause of global warming? A. Natural climate change. B. Melting ice caps. C. Human activities. D. Extreme weather. 12.What is the benefit of LED bulbs? A. They look beautiful. B. They save energy and cut CO₂. C. They are expensive. D. They are colorful. 13.How do trees help stop global warming? A. They take in CO₂ from the air. B.They produce more CO₂. C. They use up oxygen. D. They provide shade for humans. 14.Why should we use reusable water bottles? A. They are cheaper. B. They keep water warm. C. They are fashionable. D. They reduce waste and protect the environment. 15.What’s the main idea of the passage? A. Global warming is a serious problem. B. How humans cause global warming. C. Ways to help stop global warming. D. The effects of global warming. 第二节 七选五（5 小题，每题 2.5 分，满分 12.5 分） How to Live a Green Life to Fight Global Warming Living a green life means making choices that are good for the environment and help stop global warming. Here are some practical tips: 16.________ Turn off lights and electrical appliances when you leave the room. Unplug devices not in use—they still consume energy in stand-by mode. 17.________ Use reusable bags, bottles and containers. Recycle paper, plastic and glass to reduce waste and carbon emissions. 18.________ Take shorter showers and fix leaky taps. Saving water cuts the energy needed for water treatment and transportation. 19.________ Walk or ride a bike for short distances. Use public transport or carpool instead of driving alone. 20.________ Plant trees and flowers in your garden or balcony. They absorb CO₂ and improve air quality. A. Save water as much as possible B. Plant more trees and flowers C. Turn off unnecessary electrical devices D. Use disposable products as much as you can E. Choose environmentally friendly transportation F.
