2. 主題句在文中
這類文章寫法上的特點是：開始部分是引題，接著是點題，最后是對主題進行敘述，主題句常常起著承上啟下的作用。如：(全國高考題)
Fat on human beings is distributed in different ways. Some fat people have a large stomach and no waistline—which makes them look round, rather like apples. Others are fatter below the waist, which makes them appear pear-shaped.
There are two types of fat: external fat (fat under the skin) and internal fat (fat inside the body wall). Doctors, who have been examining the relationship between health and fatness, have found that the 'pears' have less internal fat, but the 'apples' have more internal fat than external fat. This seems to be what causes the health problems.
The best treatment for fatness is to reduce the internal fat. But unfortunately it seems that dieting (節食) simply makes an apple-shaped person into a smaller apple and a pear-shaped person into a smaller pear. At the moment there is no known way of reducing the internal rather than external fat.
The text is mainly about ______.
A. fatness and health B. ways to lose weigh
C. people's figures D. distribution of fat
【分析】該文的第一段交代了脂肪在體內的分布狀況；第二段交代了脂肪的種類及不同種類的脂肪與健康之間的關系；第三段講的是減肥應該減掉哪一類脂肪以及節食存在的問題。很明顯，第二段，特別是第二段的第二句，起著承上啟下的作用，是該文的主題句。A選項符合主題句的意思，應該是正確答案；B選項與文章的意思無關；可以排除；C、D選項分別只與文章的部分信息有關，也可以排除。
