Suddenly, she is pulled underwater. She surfaces, cries in fear, then disappears forever. This is the opening scene from the 1975 film Jaws, showing a shark attack. It tells the story of a great white shark that attacks and kills swimmers. Jaws was a great success, attracting huge audiences and winning many awards. It strengthened people's long-held idea of the great white shark as a dangerous animal. People have always been scared of sharks, but Jaws made things worse. It made people frightened of sharks, especially of the great white shark. Many people who saw the film started to believe that sharks were bad animals that ate humans. Some people stopped swimming in the sea, afraid of the horrible creature from the film. Other people started fishing for sharks, killing as many as they could. At that time, nobody cared if sharks were killed, or how many were killed. People just wanted them killed. 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 in shark fin soup. Finning kills millions of sharks a year. Finning would have an unexpected effect upon Peter Benchley, the man who wrote the book the film Jaws was based on. In 1980, Benchley was diving when he came across an awful sight. It was an area where fishermen were finning, and the sea floor was covered with dead sharks. Benchley saw sharks being killed and this caused a deep change in him. 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. He admitted that his book was wrong about sharks' behaviour. "Sharks don't target humans," he said. 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. Fortunately, not everyone who watched the film Jaws became afraid of sharks -some became interested in understanding them. Today, as we learn more about sharks, more people than ever want to protect them from extinction. 1. What effect did the film Jaws have on people's views of great white sharks? A. It made people think great white sharks are gentle. B. It deepened people's idea that great white sharks are dangerous. C. It made people want to learn more about great white sharks. D. It changed people's long-held idea of great white sharks. 2. Why did the number of large sharks drop quickly after 1975? A. Because many people fished for sharks to protect swimmers. B. Because sharks were killed for their fins and people's fear. C. Because the film Jaws made people stop protecting sharks. D. Because sharks couldn't adapt to the changing sea environment. 3. What is "finning" according to the passage? A. A way to protect sharks from being killed by humans. B. A type of fishing that cuts off sharks' fins and throws them back to sea. C. A method to make shark fin soup more delicious. D. A sport that people catch sharks for fun. 4. What caused Peter Benchley to change his view on sharks? A. He saw many sharks being killed by finning. B. He found his book about sharks was very popular. C. He learned that sharks never attack humans. D. He realized sharks are important to the sea. 5. What do we know about sharks from the passage? A. Sharks often target humans as their food. B. Sharks attack humans on purpose every year. C. Only about six people are killed by sharks yearly. D. Most people still think sharks are dangerous animals. 二、完形填空题 阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。 The 1975 film Jaws opens with a scary scene of a shark attacking a swimmer.

But recently, some "green truths" have been shown to be only half true, or even completely false. Here are some common ones. Which are really green? Paper shopping bags are better than plastic ones. Plastic bags cause litter and are a danger to wild animals, which mistake them for food. It takes hundreds of years for plastic to break down, but much less time for paper. Because of this, people think paper bags are the better environmental choice. However, making a paper bag uses four times as much energy as making a plastic bag and up to three times the amount of water. The process also produces more greenhouse gases. In fact, both kinds of bags are bad for the environment. So, take a reusable bag with you when you go shopping. When you turn off a device, it stops using power. When we turn off a device, such as a television, it goes into stand-by mode. Devices in this mode still use power, and older devices in stand-by mode can use even more. This happens because electricity continues to leak from the device, even when it is turned "off". To make sure your appliance is in fact off, remove the plug from its power supply. Eating local food is good for the environment. It seems like common sense: eating local food should be better for the environment, because it does not need to be transported long distances and kept cold during transport. Unfortunately, it is not that simple. It is the production of food, not its transport, that uses most of the energy and produces most of the greenhouse gases. In some cases, local produce might have used more energy and produced more greenhouse gases than produce grown a long way away-even taking into account its transport. It's better to take a shower than a bath. It depends on how long you spend in the shower and how large your bath is. If you spend more than eight minutes in a shower, you'll use as much water as in a bath-about 50 litres of water. Therefore, the key is to keep your shower time as short as possible. Environmental awareness is now part of daily life, But it's worth checking common ideas and opinions to see what's really green. 1. What do people usually think of paper shopping bags? A. They are as bad as plastic bags for the environment. B. They are better for the environment than plastic ones. C. They use less energy and water to make than plastic ones. D. They produce more greenhouse gases than plastic ones. 2. Why do devices still use power when turned off? A. Because they are in stand-by mode and leak electricity. B. Because people don't turn them off properly. C. Because older devices can't stop using power at all. D. Because the power supply is still connected to them. 3. What is the main reason for environmental pollution in food production? A. The long-distance transport of food. B. The cold storage during food transport. C. The process of food production itself. D. The use of too many chemicals in growing food. 4. When is taking a shower better than having a bath? A. When the bath is very large. B. When the shower time is less than 8 minutes. C. When you use more than 50 litres of water in a shower. D. When you take a shower instead of a bath every day. 5. What is the main idea of the passage? A. We should take steps to protect the environment. B. Most people have wrong ideas about environmental protection. C. Some common "green truths" are not completely true. D. We need to save energy and reduce waste in daily life. 二、完形填空题 阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。 Nowadays, more and more people pay attention to protecting the environment.

Many people think paper shopping bags are 2. than plastic ones. They believe paper breaks down faster and is less harmful to wild animals. But in fact, making paper bags uses much more energy and water, and 3. more greenhouse gases. Actually, both paper and plastic bags are bad for the environment. The best choice is to take a 4. bag when shopping. Another common idea is that turning off a device means it stops using power. But this is not true. When you turn off a TV or other devices, they will enter stand-by mode. In this mode, devices still 5. power, especially older ones. Electricity leaks from them even when they are turned "off". The only way to stop this is to 6. the plug from the power supply. People also think eating local food is better for the environment, as it doesn't need long-distance transport. 7. , the production of food uses more energy and produces more greenhouse gases than transport.

This 9. on your shower time and bath size. If you shower for more than eight minutes, you'll use as much water as a bath. So the key is to keep your shower time as 10. as possible.

But some popular "green truths" are not 1. (complete) true. Let's take a look at some common ones. First, people usually think paper shopping bags are better than plastic ones. They think paper breaks down 2. (fast) than plastic and is safer for wild animals. However, making a paper bag uses four times as much energy as 3. (make) a plastic bag and three times as much water. It also produces more greenhouse gases. So both kinds of bags are bad for the environment. We should take reusable bags when 4. (shop). Second, many people believe turning off a device stops it from 5. (use) power. In fact, devices go into stand-by mode after being turned off. They still use power because electricity leaks from them. To stop this, we need 6. (remove) the plug from the power supply. Third, eating local food is thought to be good for the environment. But the 7. (produce) of food uses more energy and produces more greenhouse gases than transport. Sometimes local food may be more harmful to the environment than food from far away, even after 8. (consider) transport. Finally, taking a shower is not always better than having a bath. It depends on shower time and bath size. If you shower for over eight minutes, you will use about 50 litres of water, which is the same as a bath. So we should keep our shower time as 9. (short) as possible. Environmental protection is important, but we need to check common "green truths" to make sure what we do is really 10. (help) to the environment. 答案解析（精准对标高考考点·附依据） 一、阅读理解答案 1. B 2. A 3. C 4. B 5.
