6.There has been a dramatic increase in the number of natural disasters over the past few years,and it is assumed that global warming and climate change could cause even more disasters in the future.Some of the world's leading cities are facing disasters like floods and heat waves.
London
London's flood defences are getting older.Since 1982,the Thames Barrier(水閘) has protected the city from the threat of flooding,but it was only designed to last until 2030and close once every two or three years.About 21years later the barrier now closes five or six times a year and according to Environment Agency predictions,by 2050the barrier will be closed on almost every tide if the problem is not addressed.
There are 26underground stations,400schools,16hospitals,an airport and 80billion worth of property in London's flood risk area,so large scale flooding would be disastrous.
Paris
Over a sixweek period in July and August 2008,more than 11400-mainly elderly people-died in France from dehydration (脫水) and extremely high body temperature in a deadly heat wave.Heat waves of similar intensity (強(qiáng)度) are expected every seven years by 2050,so what can be done to make sure such a disaster does not happen again?
One solution is to have airconditioners installed in elderly care homes.But this is considered a shortterm solution,as the increase in demand for electricity also increases carbon emissions.
In Paris the local authorities are encouraging architects to design new types of buildings such as the building"Flower Tower",which uses a covering of bamboo to act as a natural airconditioner.
Shanghai
Shanghai is the fastest growing city on Earth.It has a population of 18million and is only 4meters above sea level.Sea levels are predicted to rise by 20cm within the next century.
An estimated 250,000people move to Shanghai every year in search of work,placing extra demands on energy consumption.China relies heavily on coalfired power stations,but these emissions increase temperatures and,in turn,warmer seas increase the risk of typhoons.
56.Which of the following would be the best title for the passage?A
A.Big Cities Facing Big Disasters
B.Big Disasters in the Future
C.The Increase of Natural Disasters
D.Solutions to Natural Disasters
57.What problem should be settled now in London?D
A.How to protect the city's property.
B.Where to build its flood defences.
C.How to use the Thames Barrier to protect the city.
D.How to improve the function of the old flood defences.
58.Which of the following measures can't solve the heat wave disaster in Paris?C
A.Putting up new types of buildings with a covering of bamboo.
B.Having airconditioners installed in elderly care homes.
C.Forbidding the city to build"Flower Tower".
D.Encouraging architects to design new types of buildings.
59.The major threats to Shanghai areB.
A.increasing population and coalfired power stations
B.rising sea levels and typhoons
C.extremely high temperature and rising sea levels
D.extra demands on energy consumption and typhoons
60.The purpose of the passage isD.
A.to tell us how to protect the big cities
B.to give advice on how to defend natural disasters
C.to explain what causes flood and heat waves
D.to warn us of the increasing natural disasters in big cities.
分析 全文主要是圍繞著三個(gè)聞名于世的大城市面臨的災(zāi)難展開介紹的,目的就是呼吁人們關(guān)注全球變暖和氣候變化對(duì)地球的影響,希望引起人們關(guān)注災(zāi)害對(duì)大城市的破壞.
解答 56-60 ADCBD
56 A 主旨大意題.抓住關(guān)鍵詞,全文主要是圍繞著三個(gè)聞名于世的大城市面臨的災(zāi)難展開介紹的,關(guān)鍵詞是big city和disasters.選A.
57 D 細(xì)節(jié)理解題.在介紹倫敦時(shí),第一句話"London's flood defences are getting older."就點(diǎn)明了倫敦的危機(jī)暗伏的原因是防洪堤老化.所以解決的方法就是改善防洪堤.選D.
58 C 推理判斷題.在介紹巴黎時(shí),說(shuō)到了解決問題的兩種辦法,One solution is to have airconditioners installed in elderly care homes.一種是使用空調(diào),但這種辦法不是長(zhǎng)久之計(jì);另外一種In Paris the local authorities are encouraging architects to design new types of buildings such as the building"Flower Tower",就是在建筑上使用竹子屋頂型的花塔,所以A、B、D三項(xiàng)均正確,而C項(xiàng)forbid正好與文章要表達(dá)的意思相反.
59 B 細(xì)節(jié)理解題.在介紹上海這一城市時(shí),第一段It has a population of 18million and is only 4meters above sea level.說(shuō)的是海平面,第二段warmer seas increase the risk of typhoons.說(shuō)的是臺(tái)風(fēng).選B.
60 D 寫作意圖題.作者寫這篇文章的目的就是呼吁人們關(guān)注全球變暖和氣候變化對(duì)地球的影響,就全文來(lái)說(shuō),是希望引起人們關(guān)注災(zāi)害對(duì)大城市的破壞.選D.
點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力,做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句,和題干進(jìn)行比較,再做出正確的選擇.在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí),要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷.
