4、文章只有一段，看懂文章的开头两句是极为重要的。如果文章有几段，则每一段的第一句都要仔细地读，尤其是最长的一段更要注意它的主要内容。边阅读边在主题段或主题句或重要的词句下面划线，读完全文后再回过头来重读划线部分，然后就会得出作者的主要意图。1.主题句在段首一个主题句常常是一个段落的开头，其后的句子则是论证性细节。在论说文，科技文献和新闻报道中多采用这种格式。有些段落，在主题句后面有明显的引出细节的信号词。常见的信号词有for example，an example of，the most important example of；first，second，next，last，finally；to

5、begin with，also，besides that；one；the other，some，others，等等。在阅读中应尽量利用上述信号词来确定主题句的位置。例一People have different tastes in food.Some feel that they havent eaten a meal unless they have had steak or other red meat.Some prefer chicken or fish and eat one or the other at every meal.Others prefer vegetables an

6、d fruits or grains and would enjoy a meal of spaghetti（意大利面条）,eggplant,and fresh fruit.Others could live on what were called fastfoods:a hamburger or hot dog,French fries and a soft drink.()Which of the following statements best expresses the main idea of the paragraph?A.Some people like steak and o

7、thers red meat.B.Vegetables are very healthy for you.C.How food is prepared has a lot to do with how well a person may like it.D.Different people have different tastes in food.例二 请快速阅读下段文章，用划线划出文章的中心句和信号词：Smoking cigarettes is harmful to your health.Experiments show that cigarette smoking can cause

8、cancer.Besides the most serious and terrible disease(illness),cancer,cigarette smoking also can cause other health problems.For example,it can give one a“smokers cough”.Finally,studies have shown it is easy for cigarette smokers to catch colds.Whether you get an unimportant cold or terrible killer,c

9、ancer,smoking is harmful.Is it worth it?KEY：Smoking cigarettes is harmful to your health.2.主题句在段尾一般说来，当一种观点不易向人解释清楚，或不易被人接受时，主题句便会到段落的末尾才出现。有些文章以列举事实依据开头，通过论证，最后讲出作者自己所阐述的核心论点。在做阅读理解试题时，要充分利用引出结论的信号词，如clearly，plainly；so，therefore，thus，consequently；In conclusion，in short等来确定主题句的位置在段尾。当无明显的此类信号同时，可添加一

10、个引出结论的信号词以确定主题句是否是段落的最后一句话。例一 Americans might be embarrassed because their Japanese friends are so formal with them.Japanese might feel insulted because American acquaintances greet them casually.Still,the forms of greeting in both countries only show respect for others.It just happens that American

11、s and Japanese have a different way of looking at human relationships and thus have a different way of showing respect.This passage mainly tells us_.A.how Americans show respect to othersB.how Japanese show respect to their American acquaintancesC.Americans and Japanese have different ways of showin

12、g respectD.Japanese are not satisfied with American casual behavior例二 请快速阅读下段文章，用划线划出文章的中心句和信号词：Often no one looks more guilty than the innocent（清白的）.On the other hand,nobody may look more innocent than a professional criminal.And the man who knows“everything”may really only be trying to hide his ow

13、n weakness.So,it is foolish to try to judge a person only by his appearance.KEY：So,it is foolish to try to judge a person only by his appearance.3.主题句在段中有时段落是先介绍背景和细节，接着用一句综合或概括性的话概括前面所说的内容或事例，然后再围绕主题展开对有关问题的深入讨论。这种文章的主题句往往会在段落中间出现，但不是就在正中间。请阅读下列短文并找出主题句例一Nothing is as useful as a flashlight on a da

14、rk night if a tire goes flat.Few inventions are so helpful to a child who is afraid of the dark.In fact,the modern flashlight brings light to many dark situations.Finding something in the back of a closet is easy with a flashlight in hand.A camper also needs one after the light of the campfire has b

15、een out.例二 Just as I settle down to read or watch television,he demands that I play with him.If I get a telephone call,he screams in the background or knocks something over.I always have to hang up to find out whats wrong with him.Baby-sitting with my little brother is no fun.He refuses.to let me ea

16、t a snack in peace.Usually he wants half of whatever I have to eat.Then,when he finally grows tired,it takes about an hour for him to fall asleep.Baby-sitting with my little brother is no fun.（二）找主题词有时段落中没有明显的主题句。作者用一种间接的方式表达了段落的中心思想。这时我们不能轻而易举地判断出主旨或主题这样，主题句是含蓄的，它隐含在短文或段落之中，需要考生从段落中寻找主题词或词组。然后用这些主题

17、词或词组概括和归纳出段落的中心思想。例一Bats are the only animals that truly fly.These animals use their leathery wings differently from birds.Birds flap their wings up and down,while bats use both their wings and legs,which make them seem as if they are swimming through the air.Even though bats take much longer,strong

18、er strokes than birds,they still can beat their wings as often as twenty times per second!此段落的主题词是：bats,birds,different,flyThe main idea of this paragraph is that _ Bats are different from birds in flying.例二Joshua Bingham studied four years at the University of Paris and decided to leave before his

19、graduation.He transferred to the University of Berlin and graduated with honors.Harvard Law School and,later,Boston College provided him with an excellent legal background.He is presently a corporation lawyer in Miami,Florida.此段落的主题词是：study at the university,graduate with honors三.实战演练A/B/C(A)（Monday
