20xx秋人教版高三英语上学期第二次月考试题内容摘要：

ver, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’ s surface. The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment! What you need ● A hardboiled egg without the shell ● A bottle with a neck slightly smaller than the egg ● A piece of paper ● A match Method Check that the egg will sit firmly on the neck of the bottle. Tear the paper into strips and put the strips into the bottle. Light the paper by dropping a burning match into the bottle. Quickly sit the egg on the neck of the bottle. Result Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches. Why it happened As the paper burns, it needs oxygen and uses up the oxygen(air) in the bottle. The egg acts as a seal in the neck of the bottle， so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air presses against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on us. 32. Why is there the need to take care when you are doing the experiment? A. The bottle could break. B. You need to light the paper with a match. C. The egg needs to be shelled. D. The egg has to be perfectly placed on the neck of the bottle. 33. In the experiment, the burning inside the bottle can . A .equalize the air pressure inside and outside B. make a seal in the neck of the bottle C. finish up the oxygen inside the bottle D. Produce more oxygen inside the bottle 34. How did the egg get into the bottle? A. The oxygen inside the bottle sucked the egg in. B. It became soft without the shell. C. The neck of the bottle was wide enough. D. The outside air pressure forced it into the bottle. 35. The experiment is carried out to prove . A. water pushes on your body when you swim underwater B. the earth is surrounded by a layer of air called the atmosphere C. the pressure of air around us has a powerful force D. the air pressure is not equalized around us 第二节（共 5小题；每小题 2分，满分 10分） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。 选项中有两项为多余选项。 False Fear of Big Fish Many people believe sharks are dangerous and will always try to hurt or even kill humans. 36 A shark exhibition at the National Aquarium(水族馆 ) in Baltimore, US, proves this. Visitors can touch young sharks, see their eggs develop and watch a dozen different species swim smoothly around a huge tank. Most people fail to realize that attacks don’t happen very often. Humans are more likely to be killed by lightning than by a shark. 37 There , kids can learn, from an early age, not to fear sharks. “People fear what they don’t know,” said Nancy Hotchkis s, an anizer of the exhibition. “Sharks have been around for 400 million years and play an important role in the ocean’s food chain. We want people to discover that sharks are amazing animals that need our respect and protection.” 38 A study, published in January in the US magazine, Science, found that almost all recorded shark species have fallen by half in the past 8 to 15 years. Thousands of sharks are hunted in Asia for special foods, such as shark fin (鱼翅 ) soup. And many others get caught in s, while fishermen are hunting other fish. 39 “Some fishing methods are actually cleaning out the ocean for sharks,” said Dave Schofield, the manager of the aquarium’s ocean health program. 40 A. They can watch them develop inside their eggs and feel the skin of the older swimmers. B. A shocking 100 million sharks are killed every year around the world by humans. C. In fact, 94 percent of the world’s 400 species are harmless to humans. D. It is a worrying situation and some areas have put measures in place to protect these special fish. E. And to make this point clear, the museum has set up a special touching pool for children. F. More than half of the sharks caught are smaller than one meter long. G. . Sharks can smell and taste blood , and trace it back to its source. 第三部分 英语 知识运用（共两节，满分 45分） 第一节 完形填空（共 20小题；每小题 ，满分 30分） 阅读下面短文，从短文后各题所给的四个选项（ A、 B、 C 和 D）中选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。 My husband ,Tom, has always been good with animals, but I was still amazed when he befriended a female grouse(松鸡 ) .It ’s 41 for a grouse to have any contact with people.
