Mark your answers on ANSWER SHEET 1. 20 Global warming could cause drought and possibly famine in China, the source of much of Hong Kongs food, by 2050, a new report predicts. Hong Kong could also be at risk from flooding a
11、s sea levels rose. The report recommends building sea walls around low-lying areas such as the new port and airport reclamations and uses the most recent projections on climate change to point to a gloomy outlook for China. By 2050 about 30 to 40 percent of the country will experience changes in the
12、 type of vegetation it supports, with tropical and sub-tropical forest conditions shifting northward and hot desert conditions rising in the west where currently the desert is temperate. Crop-growing areas will expand but any benefit is expected to be negated by increased evaporation of moisture, ma
13、king it too dry to grow crops such as rice. The growing season also is expected to alter, becoming shorter in southern and central China, the mainlands breadbasket. The rapid changes make it unlikely that plants could adapt. “China will produce smaller crops. In the central and northern areas, and t
14、he southern part, there will be decreased production because of water limitations,“ said Dr. Rik Leemans, one of the authors of the report. Famine could result because of the demands of feeding the population particularly if it grows and the diminished productivity of the land. “It looks very diffic
15、ult for the world as a whole“, he said. Dr. Leemans said Chinas reliance on cola-fired power for its industrial growth did not bode well for the world climate. “I think the political and economic powers in China are much greater than the environmental powers, and (greenhouse gas emissions) could acc
16、elerate“, Dr. Leemans said. “China is not taking the problem seriously yet, although it is trying to incorporate this kind of research to see what is going to happen.“ The climate change report, which will be released tomorrow, focuses on China but Mr. David Melville of WWF-Hong Kong said some of th
17、e depressing scenarios could apply to Hong Kong. Food supplies, for instance, could be affected by lower crop yields. “Maybe we could afford to import food from elsewhere but you have to keep in mind that the type of changes experienced in southern China will take place elsewhere as welt“, he said.
18、Sea levels could rise as glaciers melted and the higher temperatures expanded the size of the oceans, threatening much of developed Hong Kong which is built on reclaimed land. “Hong Kong has substantial areas built on reclaimed land and sea level rises could impact on the whole area“, Mr. Melville s
19、aid, adding that sea walls would be needed; Depleted fresh water supplies would be another problem because increased evaporation would reduce levels. 21 Overall, what sort of picture is painted of the future effects of global warming? ( A) Disastrous. ( B) Potentially disastrous. ( C) Relatively opt
20、imistic. ( D) On balance things are going to be satisfactory. 22 Mr. David Melville suggests that in future more food could be imported into Hong Kong. He thinks these measures could be _. ( A) efficient ( B) sufficient ( C) insufficient ( D) inefficient 23 The main point of paragraph two is to desc
21、ribe _. ( A) effects of changes in the climate of China on food production ( B) future changes in the vegetation ( C) future changes in the growing season ( D) projected future changes in the climate of China 24 How would you describe the Dr. Leemans attitude towards China? ( A) Mainly favorable. (
22、B) Critical. ( C) Supportive in theory. ( D) Admiring. 25 In Paragraph “negated“ is closest in meaning to _.

25、ns: Read the following three texts. Answer the questions on each text by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. 【知识模块】 天气与气候 21 【正确答案】 B 【试题解析】 文章开始就谈到 2050年,全球变暖会导致干旱和饥荒;第二段也说到 2050年,植被条件会发生变化,种植季节也会随之发生变化,这些结果都是灾难性的,但这些灾难都不是马上发生的,所以,还只能说是潜在的灾难,故选D。 【知识模块】 天气与气候 22 【正确答案】 C 【试题
26、解析】 原文倒数第二段 Maybe we could afford to import food from elsewhere but you have to keep in mind that the type of changes experienced in southern China will take place elsewhere as well Mr Melville的意思是说,其他的地方也同样会因为气候变得干旱而导致粮食减产,从而没有更多的粮食供应出口,所以,进口粮食的措施是不足以解决问题的。 C中 “不足的、不够的 ”符合文中表达的意思。 【知识模块】 天气与气候 23 【
27、正确答案】 D 【试题解析】 本段涉及的内容包括植被类型的变化、降水的变化及种植季节的变化,而这些都可归结到气候的变化,因此, D为本题的答案。 【知识模块】 天气与气候 24 【正确答案】 B 【试题解析】 文中第四段提到, Dr. Leemans认为,中国的经济和政治力量要大于环保方面的力量,所以,尽管中国正在开展这方面的研究,但并没有很严肃地对待环保问题,而实际上,这一方面的问题十分严重,如果不认真对待,可能会产生更严重的后果。所以,他基本上持一种批评的态度,故选 B。 【知识模块】 天气与气 候 25 【正确答案】 A 【试题解析】 根据 negate本身的词义和原文中整句的含义得出该词带有否定含义,即 “消除、使无效 ”,所以, A是正确选项。 【知识模块】 天气与气候
