By the time the forest fires were finally over, some 8 million hectares ( 公顷 ) of land had burned while countless millions of people suffered from air pollution.

Reading Reading strategies: Completing Texts with sentence gaps Read the text to get the general idea. Read a paragraph with a sentence gap and identify the topic, e.g. disasters. Read the sentences before and after the gap and look for clues about the missing

sentence, e.g. is it an example of what is mentioned before? Certain words may help you: time references (then). pronoun references (it, that), linking words (however). Decide which sentence goes in the gap. check that it fits the sentences before and after it.

1. Use the strategies to complete the gaps in the text (1-5) with these sentences (a-g). There are two extra sentences you do not need. a) But evidence shows that years ago there was a much greater eruption. b) Even Europe has suffered and large areas have been under water. c) That is probably not the most important factor either.

d)Third, the other bits of land you might have been able to farm are now useless. e)On top of all that add global warming. f)For example, the yellow river, once famous for flooding, failed to reach the sea at all for 226 days in g)One answer is overpopulation. Answers: 1. ___ 2. ___3. ___ 4. ___ 5.___ b fgea

1) The main reason why more natural disasters happen now is _______. A. that more and more people move to cities B. that volcanoes break out more frequently than before C. that earthquakes are even more dangerous than in the past D. overpopulation and mismanagement of the world’s resources 2. Choose the best answer to each question according to the text. Answer: D

2) In the future, the biggest threat to human beings may be __________. A. volcanic eruption B. unnatural disasters C. floods and droughts D. typhoons and tsunamis Answer: A

3) The threat to humans from volcanoes is even more serious because ______. A. more and more forests are destroyed by humans B. many people now live within the range of a volcanic eruption C. the population of the world is growing rapidly D. more carbon dioxide is produced by factories and vehicles Answer: B

3. Read the text again and answer these questions. 1) What is the attitude of the journalist towards the future? 2) Who are most likely to be the victims of natural disasters? Pessimistic/Negative. Poor people.

3) Why are there now more hurricanes, floods and droughts? 4) Why are volcanoes and earthquakes more dangerous now? Overpopulation and mismanagement of the world’s resources. Because around half the world’s population lives in cities, more than 500 million people now live within the range of volcanic eruption and an even greater number of people live at risk from earthquakes.

5) What could be the biggest threat to the planet in the future? 6) What effects might this threat have? A volcanic eruption. It might send the planet into winter for years.

Structure Analysis 1. This catastrophe is still very fresh in the minds of people worldwide who have not yet got over their separation from loved ones lost in the tsunami. 译文： 在世界各地许多人的心目中, 那 场灾难仍然记忆尤新。他们还没有从 海啸中丧失亲人的打击中恢复过来。

在这个复合句中， who have not yet got over their separation from loved ones lost in the tsunami 为定语从句，修饰 people 。在定语从句中， lost in the tsunami 为过去分词短语作定语，修饰 ones 。 结构分析：

2. People in agriculture areas, without any means to earn their living, move to the cities, and then construct shabby homes from whatever materials they can find on poor clay soil. 译文： 农业地区的人口，因为没有办法 谋生而流向城市。他们用在贫瘠的土 地上用可以找到的任何材料搭建起破 烂的房屋。

结构分析： 在这个复合句中， without any means to earn their living 为复合结构， 在句中作原因状语。 whatever materials they can find 是宾语从句， 在句中作介词 from 的宾语。

3. An even greater number of people live at risk, to some degree, from earthquakes which have claimed more than 1.6 million lives in the last hundred years. 译文： 从某种程度上来说，有更多的人 处在地震的危险中，在过去的几百年 间地震已经夺去了 160 多万人的生命。

结构分析： 这是一个主从复合句， an even greater number of people live at risk 是 主句。 From earthquake 是介词词组作 定语修饰 risk ； which have claimed more than 1.6 million lives in the last hundred years 是 claimed 的宾语从句； more than “ 超过 ” ，修饰 1.6 million ； to some degree 是插入语。
