主旨大意类题主题句在文末和无主题句解题方法
1. 主题句在文末
这类文章写法上的特点是：在叙述完某件事情或某个话题之后，用一句话交代事情的结果或对前面的叙述进行归纳。如：
El Nifio, a Spanish term for “the Christ child”, was named by South American fisherman who noticed that the global weather pattern, which happens every two to seven years, reduced the amount of fishes caught around Christmas. El Nifio 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 both good and bad, are felt in many places. Rich countries gain more from powerful Nifio, on balance, than they lose. A study found that a strong Nifio in 1997 helped American’s economy grow by 15 billion, partly because of better agricultural harvest, farmers in the Midwest gained from extra rain. The total rise in agricultural in rich countries in growth than the fall in poor ones.
But in Indonesia extremely dry forests are in flames. A multi-year drought (干旱）in south-east Brazil is becoming worse. Though heavy rains brought about by El Nino may relieve the drought in California, they are likely to cause surface flooding and other disasters.

The most recent powerful Nino, in 1997-98, killed around 21,000 people and caused damage worth $36 billion around the globe. But such Ninos come with months of warning, and so much is known about how they happen that governments can prepare. According 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 reconstruction.

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 to a paper in 2011 by Mr Hsiang and co-authors, civil conflict is related to El Nino’s harmful effects—and 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 are followed by killing and wounding people. Since the poorest are least likely to make up for their losses from disasters linked to El Nino, reducing their losses needs to be the priority.
Q:What is the author’s purpose in writing the passage?
A.To introduce El Nino and its origin.
B.To explain the consequences of El Nino.
C.To show ways of fighting against El Nino.
D. To urge people to prepare for El Nino.
【答案】D
【解析】目的意图题。根据最后一句“Since the poorest are least likely to make up for their losses from disasters linked to El Nino, reducing their losses needs to be the priority.”各国政府要把减少损失放在优先的位置。也就是说我们要事先做好准备。故D项正确。

2.无主题句
这类文章写法上的特点是：中心主题隐含在全文之中，没有明确的主题句。阅读这样的文章，就要求考生根据文章的细节来分析，概括出段落的主题，从而推导出文章的主旨。分析的方法是，先弄清该段落主要讲了哪几个方面的内容，这些内容在逻辑上有什么联系，然后加以归纳形成主题。该类型的试题则迎刃而解。如：
When her five daughters were young, Helene always told them that there was strength in unity (团结). To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.
...
Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."
Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.
Q:Which of the following can be the best title for the passage?
A.How to Run a Corporation
B. Strength Comes from Peace
C. How to Achieve a Big Dream
D. Family Unity Builds Success
【答案】D
