1、 Unit 1Great scientists推理判断题之写作目的题(阅读理解)方法指导推断写作目的的题目题干中常有purpose或表示目的的动词不定式等。推断作者写该篇文章的目的,有两大思路,解题时要综合考虑:1.主旨推断法写作意图与文章主旨密切相关,因此,解答这类题跟解答主旨大意题和选择文章标题一样,用略读法,即重点关注文章首尾段和各段的首尾句,找到主题句,抓住文章主旨,然后由主旨来推断作者的写作目的。议论文、新闻报道、说明文等,其主题句多在文首。2.文体推断法作者的写作目的与文体密切相关。 (1)议论文的目的通常是说服读者接受或赞同某一观点,倡导某种做法等。(2)说明文的目的是使读者获得
2、某种知识,提出某种建议、劝告或呼吁,或希望引起有关部门或人士对某种现象给予重视。(3)记叙文的目的一般是分享一段有趣的经历,告诉读者一个有趣的故事,使读者获得乐趣;若是夹叙夹议的文章,则是表达作者的感悟或给读者某种教育或启示。(4)广告是作者要推销一种产品或一种服务,因此其目的是吸引更多顾客、游客、读者、订户、观众等。典例引领 (2016江苏,C)El Nio, a Spanish term for “the Christ child”, was named by South American fishermen who noticed that the global weather patt
3、ern, which happens every two to seven years, reduced the amount of fishes caught around Christmas. El Nio sees warm water, collected over several years in the western Pacific, flow back eastwards when winds that normally blow westwards weaken, or sometimes the other way round.The weather effects, bo
4、th good and bad, are felt in many places. Rich countries gain more from powerful Nios, on balance, than they lose. A study found that a strong Nio in 1997-98 helped Americas economy grow by$15 billion, partly because of better agricultural harvests:farmers in the Midwest gained from extra rain. The

A multi-year drought(干旱)in south-east Brazil is becoming worse. Though heavy rains brought about by El Nio may relieve the drought in California, they are
6、likely to cause surface flooding and other disasters.The most recent powerful Nio, in 1997-98, killed around 21,000 people and caused damage worth$36 billion around the globe. But such Nios come with months of warning, and so much is known about how they happen that governments can prepare. Accordin
7、g to the Overseas Development Institute (ODI), however, just 12% of disaster-relief funding in the past two decades has gone on reducing risks in advance, rather than recovery and rebuilding afterwards. This is despite evidence that a dollar spent on risk-reduction saves at least two on reconstructi
8、on.Simple improvements to infrastructure(基础设施)can reduce the spread of disease. Better sewers(下水道)make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach. Stronger bridges mean villages are less likely to be left without food and medicine after floods. According
9、to a paper in 2011 by Mr Hsiang and co-authors, civil conflict is related to El Nios harmful effectsand the poorer the country, the stronger the link. Though the relationship may not be causal, helping divided communities to prepare for disasters would at least reduce the risk that those disasters a
10、re followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Nio, reducing their losses needs to be the priority.1.What can we learn about El Nio in Paragraph 1?A.It is named after a South American fisherman.B.It takes place a
