but 的启示功能研究研究历年高考阅读理解试题，我们会发现but/however是一个重现率极高的词汇，它有很强的启示功能， 对我们判断上下文文意、推断作者的态度、判明人物心理、理清文章层次都具有举足轻重的作用。 一．but引出相反或相对的信息。利用but 的这一功能，可以快速、准确地推知上下文的意义。 例（07江西） Until 1954 it was thought that no man could run one mile in less than four minutes. As years 36 ,the record came closer and closer to four minutes and Roger Bannister, a young English 37, began to believe be might 38 this almost magic barrier. It was a cold afternoon on May 6th, 1954, when Bannister knew be had a 39 chance. Bannister had been 40 hard and was very fit, but the weather conditions were a real 41 to him. Describing the 42 later , Bannister said, On the way to the track the wind blew strongly. As I 43 for the start I glanced at the flag. It moved 44 now.

About 90% of the sugar is produced as food. Only 10% is used in industry for purposes other than food production. Yet sugar has great possibilities for use as the basis of chemicals. It can even be used for making plastics. In the future these potential uses will certainly be developed more than in the past. There are many reasons why we should increase the production of sugar. Most important is that it is one of the most highly concentrated of energy foods. Thus sugar cane and beet produce an average of 7, 000, 000 calories per acre. In this way they have the advantage over potatoes which give only 4,000,000, while the figure for wheat and beans is 2,000,000 each.
