global warmingsection a本文词数:302 参考时间:240rising 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 peninsulas 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

caused by global warming. 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:200read 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 dont 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. to introduce the causes and effects of gulf stream.阅读新题型本文词数:279 参考时间:245阅读短文,根据要求完成文后题目。an inconvenient truth is an american documentary film about global warming. it is presented by former united states vice president, al gore, and directed by davis guggenheim. the film premiere was at the sundance film festival and opened in new york and los angeles. a book of the same name by gore, an inconvenient truth: the planetary emergency of global warming and what we can do about it, reached no.1 on the new york times best-seller list. the documentary was also voted one of the best documentaries.gore said he became interested in global warming when he took a course at harvard university. later, when gore was in congress1, he called for people to pay more attention to the subject. after his defeat in the 2000 presidential election, gore gave more of his attention to the topic. he edited and adapted a slide show. it talks about global warming across the u.s. and around the world. gore also reviews scientific opinions on climate change, discusses the politics and economics of global warming and describes the influence of global climate change in the slide show.producers laurie david and lawrence bender saw gores slide show in new york city after its first release2. inspired, they met with director davis guggenheim about the possibility of making the slide show into a movie.the documentary ends with go
