信息归纳 (本部分共5小题，每小题1分，共5分) Scientists who study the climate (气候) are still arguing about how fast the earth is warming and how much it will warm, but they do agree that the earth is warming and that it will keep warming if we don’t do anything about it. Scientists agree that the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape (释放) into the air and that these gases are causing most of the warming. Another cause is deforestation ( cutting down trees ) . Trees soak up carbon dioxide  (二氧化碳) , one of the greenhouse gases, from the air. There are already some changes happening because of global warming. Sea level is rising and some animals are already moving to new homes. It’s already too late to stop global warming completely. If the warming gets worse, as scientists expect, there may be some kinds of plants and animals that become extinct (灭绝的) because they can’t move to new homes. There may be more storms and floods. Sea level may rise so much that people have to move away from the coasts. Some areas may become too dry for farming. Global warming is a very difficult problem to fix. People are having a hard time agreeing on what to do about it. For example, everyone agrees that wasting energy is a bad thing to do. But some people think that the federal government (联邦政府) should make laws about it, while other people think it should be up to each person or business to decide what to do. Many states and businesses in the United States are not waiting until the federal government decides what to do. They have already started working on the problem. 根据短文内容，完成下面表格中的信息。每空词数不限。 Global warming Causes 1. ______                 __  ; 2. _______                _  ;  Possible results 3. _______                 _  . Plants and animals become distinct. 4. _____             _   __  . People move away from coasts. Some areas become too dry for farming. What to do 5. _______                _  .

题型：完形填空  难度：偏易

答案

1. Burning of fossil fuel    2. Deforestation 3. Sea level is rising and some animals are already moving to new homes 4. There are more storms and floods    5. Stop wasting energy

1和2处要求填写全球变暖的原因。第二自然段介绍了导致全球变暖的两个原因。the burning of fossil fuels (化石燃料) like oil and coal cause greenhouse gases to escape (释放) into the air and that these gases are causing most of the warming. Another cause is deforestation ( cutting down trees ) .所以1处填写the burning of fossil fuels；2处填写deforestation。 3和4处要求填写全球变暖产生的可能后果。第三自然段介绍了由于全球变暖已经发生的变化，Sea level is rising and some animals are already moving to new homes.所以，3处的答案就很明了了。第四自然段介绍了气候继续变暖的可能后果，其中本段第二句提到There may be more storms and floods.题干当中没有涉及，故4处应该填入此内容。 5处要求填写应对全球变暖，需要做什么。倒数第二自然段提到：For example, everyone agrees that wasting energy is a bad thing to do. 所以，我们不应浪费能源，故5处可填写Stop wasting energy。
