Question

【題目】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.

試題分析：這篇短文主要講述美國科學(xué)家、政治家本杰明.富蘭克林通過具體實驗，證明黑色比白色更能吸收熱量，從而使得人們在夏天熱衷于穿白色的衣服，戴白色的帽子。

【1】F細節(jié)理解題。根據(jù)短文“He was a very famous American statesman”，的敘述可知，富蘭克林他不僅是個科學(xué)家,還是個政治家。因此這個敘述是錯誤的，故填F。

【2】T細節(jié)理解題。根據(jù)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.”的敘述可知，是一個朋友告訴富蘭克林黑色比白色吸熱。因此這個敘述是正確的，故填T。

【3】T細節(jié)理解題。根據(jù)第二段弗蘭克林的實驗結(jié)論“This proved to him that the black cloth held the heat better than the white cloth.”可知，黑色的東西比白色的東西吸熱性更好，因此這個敘述是正確的，故應(yīng)填T。

【4】F細節(jié)理解題。根據(jù)短文的敘述可知，弗蘭克林的實驗是在雪地里進行的，所以應(yīng)該是冬天，而不是夏天。因此這個敘述是錯誤的，故填F。

【5】T根據(jù)短文最后一段“ people began to wear white hats and white clothes during the summer because they were cooler.”的敘述可知，人們在夏天熱衷于穿白色的衣服，戴白色的帽子是因為它比較涼快。

因此這個敘述是正確的，故應(yīng)填T。
