5. 文章中没有明显的主题句
有的文章没有明显的主题句，如果在阅读这类文章的时候碰到判断文章的主题、话题、中心思想之类的题目，我们的注意力主要放在两个方面：1. 文章的主要内容；2. 选项之间的区别。也就是说能涵盖文章的全部或主要内容的选项才是正确答案。如：(全国高考题)
James Cleveland Owens was the son of a farmer and the grandson of black slaves. His family moved to Cleveland when he was 9. There, a school teacher asked the youth his name.

"J.C.", he replied.

She thought he had said "Jesse", and he had a new name.

Owens ran his first race at age 13. After high school, he went to Ohio State University. He had to work part time so as to pay for his education. As a second-year student, in the Big Ten games in 1935, he set even more records than he would in the Olympic Games a year later.

A week before the Big Ten meet, Owens accidentally fell down a flight of stairs. His back hurt so much that he could not exercise all week, and he had to be helped in and out of the car that drove him to the meet. He refused to listen to the suggestions that he give up and said he would try, event by event. He did try, and the results are in the record book.

The stage was set for Owens' victory at the Olympic Games in Berlin the next year, and his success would come to be regarded as not only athletic(体育的)but also political. Hitler did not congratulate any of the African-American winners.

"It was all right with me," he said years later. "I didn't go to Berlin to shake hands with him, anyway."

Having returned from Berlin. He received no telephone call from the president of his own country, either. In fact, he was not honored by the United States until 1976, four years before his death.

Owens' Olympic victories made little difference to him. He earned his living by looking after a school playground, and accepted money to race against cars, trucks, motorcycles, and dogs.

"Sure, it bothered (烦扰)me," he said later. "But at least it was an honest living. I had to eat."

In time, however, his gold medals (奖牌) changed his life. "They have kept me alive over the years," he once said. "Time has stood still for me. That golden moment dies hard."
Which of the following is a suitable title for the text?
A. Jesse Owens, a Great American Athlete
B. Golden Moment — a Life-time Struggle
C. Making a Living as a Sportsman
D. How to Be a Successful Athlete?
【分析】这篇文章简明扼要地介绍了奥林匹克金牌得主，美国黑人运动员James Cleveland Owens辉煌而又坎坷的人生，但文章侧重介绍的是他人生的坎坷，而不是他人生的辉煌。B选项侧重的是他人生的辉煌，而不是他人生的坎坷，不能涵盖文章的主要意思，因而不合题意；C、D选项与文章的内容无关，也不合题意；James Cleveland Owens在获得奥林匹克金牌后虽然没有立即得到美国社会的重视，但获得金牌奠定了他作为一名伟大的运动员在美国田径运动史上的重要地位却是不争的事实，A选项既表达了文章的这一主要意思，也能涵盖他人生辉煌及坎坷的不同侧面，比较全面地反映了文章的主要内容，因而符合题意，是正确答案。
以上从五个方面介绍了判断文章主题的主要方法，但要真正掌握并熟练运用这些方法也不是能一蹴而就的事情，还需要在大量的阅读实践中不断思考，总结，得出自己的体会。
