Global WarmingSection A本文词数:302 参考时间:2'40''Rising temperatures in coming years would lead to less sea ice in the Southern Ocean that surrounds Antarctica and fewer habitats and feeding grounds for penguins, says the World Wildlife Fund (世界自然基金会) in its report 2 Degrees is Too Much.Antarctica and the Arctic are the most threatened regions from climate change. In the Antarctica, the temperature has risen 2.5 degrees in the past 50 years. This speed is nearly five times faster than that before the Industrial Revolution. It is mainly caused by burning fossil fuels. Unless nations reduce carbon dioxide emission1, the world will warm by an average of 2 degrees in less than 40 years. Rich nations should agree to reduce greenhouse gas emission. Temperatures near the Poles have risen much faster, which has led glaciers2 on the Antarctic Peninsula to melt3 quickly.The situation is quite critical, because in the past 50 years the number of emperor penguins (帝企鹅) has decreased by 50 percent across the whole Antarctica. On the Antarctic Peninsula’s northwest coast, the number of Adelie penguins (阿德里企鹅) has dropped surprisingly over the past 25 years.Fifty percent of the habitats of the emperor penguin and 75 percent of the habitats of the Adelie penguin face a rapid reduction, or even disappearance, if the global temperature rises 2 degrees above pre-industrial levels.With a 2-degree increase in global temperature and the decrease in sea ice thickness, emperor penguins will find it difficult to find new areas to live. With less sea ice, penguins could be pushed further south, but this could prevent them from hunting for food during the dark winters, because they need at least a few hours of daylight to find their food.Notes:1. emission n. 排放2. glacier n. 冰川3. melt v. 融化词数:150处理时间:2′45″Read the passage and then choose the best answer for each question.1.

Much of the science in the movie has been questioned by people. However, there may be some truth to the idea in the movie that global warming could cause an ice age.The theory starts with an understanding of why Europe and Scandinavia are not colder already. After all, other places at the same latitude1 are covered with ice. The ocean current2 called the Gulf Stream (墨西哥湾流) brings warm waters from the Caribbean to the UK and Europe. These waters warm the countries around their path. This is why the UK, Europe and Scandinavia have a warmer climate than Alaska. Global warming has nothing to do with this. Global warming is significant3. It could slow the Gulf Stream, or even stop it. If this were to happen, the cold waters would stay in the area of Europe, the UK, Scandinavia and the North-eastern US. It could mean an ice age for those regions.Some weakness in the Gulf Stream could happen for different reasons. These days, it could happen due to global warming, caused by human activities, such as the burning of fossil fuels.If a new ice age happens, it will probably be caused by the melting of the polar ice. This will lead large quantities of cold and fresh water to come into the ocean. This would disrupt the Gulf Stream and cause the cooling of many areas that now have a mild climate.Scientists have gathered a lot of data from the oceans and the land to try to determine whether an ice age could be caused by global warming. With all this information at hand, it appears that it is indeed possible that global warming could lead to an ice age.Notes:1. latitude n. 纬度2. current n. 水流3. significant adj. 有重大意义的；显著的词数:171 处理时间:2'00''Read the passage and then choose the best answer for each question.1. What does the author tell us in the second paragraph?A. Global warming has created a warmer climate in the UK, Europe and Scandinavia.B. The Gulf Stream plays an important role in the warm climate of the UK, Europe and Scandinavia.C. Only the burning of fossil fuels can cause global warming.D. The climate of Alaska is also affected by the Gulf Stream.2. By saying "Global warming is significant.", the author means the following except ______.A. the Gulf Stream will be slowed down or stoppedB. the cold water will stay in the ocean of these areasC. people don’t have to suffer from coldD. an ice age is just waiting to happen in some areas3. Why does the author write this passage?A. To warn people of the dangerous effects of global warming.B. To prove that the polar ice will disappear.C. To prove that a new ice age is no way to come.D.
