Question

【题目】We all know who Benjamin Franklin was. He was a very famous American statesman. He was also the first man to discover electricity. Franklin liked to study and to learn about new things. One day he heard from a friend that something black in colour holds the heat better than something white in colour. Franklin wanted to find out if this was true or not.

There was snow on the ground at the time. So he put two large pieces of cloth over the snow. One piece of cloth was black in colour, the other piece was white. Then he waited until the sun began to shine. After several hours he looked under the pieces of cloth and saw that the snow under the black cloth melted(融化) much faster than the snow under the white cloth. This proved to him that the black cloth held the heat better than the white cloth.

Soon after this, people began to wear white hats and white clothes during the summer because they were cooler.

Judge the following statements True (T) or False (F)

【1】Benjamin Franklin was only a scientist.

【2】One day a friend of his told him something about the relation(关系) between colour and heat.

【3】Something black in colour holds heat better than something white in colour.

【解析】

试题分析：这篇短文主要讲述美国科学家、政治家本杰明.富兰克林通过具体实验，证明黑色比白色更能吸收热量，从而使得人们在夏天热衷于穿白色的衣服，戴白色的帽子。

【1】F细节理解题。根据短文“He was a very famous American statesman”，的叙述可知，富兰克林他不仅是个科学家,还是个政治家。因此这个叙述是错误的，故填F。

【2】T细节理解题。根据短文第一段“One day he heard from a friend that something black in colour holds the heat better than something white in colour.”的叙述可知，是一个朋友告诉富兰克林黑色比白色吸热。因此这个叙述是正确的，故填T。

【3】T细节理解题。根据第二段弗兰克林的实验结论“This proved to him that the black cloth held the heat better than the white cloth.”可知，黑色的东西比白色的东西吸热性更好，因此这个叙述是正确的，故应填T。

【4】F细节理解题。根据短文的叙述可知，弗兰克林的实验是在雪地里进行的，所以应该是冬天，而不是夏天。因此这个叙述是错误的，故填F。

【5】T根据短文最后一段“ people began to wear white hats and white clothes during the summer because they were cooler.”的叙述可知，人们在夏天热衷于穿白色的衣服，戴白色的帽子是因为它比较凉快。

因此这个叙述是正确的，故应填T。
