二、阅读（共两节，满分35分）

第一节　阅读理解（共15小题；每小题2分，满分30分）

阅读下列短文，从21—35各题所给的A、B、C、D项中选出最佳选项。

(A)

Spencer Silver wanted to make a strong glue. Instead, he made one that stuck only lightly. Paper joined with it could easily come apart. It did not meet his original goal, but Silver kept telling other scientists about it.

Art Fry, one of his colleagues, had a small problem. Paper bookmarks kept falling out of his songbook. He needed a temporary bookmark. It should stay in place while he sang, then come off without hurting the page.

Fry remembered Silver's glue. The two worked together to put it on paper. The new bookmark worked. Then, as people at their company wrote messages on the little pieces of paper and passed them around, they discovered another use. The pieces could carry notes as well as mark pages.

The product did not immediately sell well everywhere. Later, when people received samples and tried them, many understood its value. These small notes became known as Post-it Notes. Their story shows why a discovery can wait for years before becoming useful: someone needs to connect it with the right problem.

注：glue 胶水；colleague 同事；sample 试用品。
