　　試題解析

　　1.選B.本題為主旨歸納題。本文主要介紹了日食對動物和人類的影響以及日食發(fā)生的原因，都和日食有關。所以選B.

　　2.選D.本題為推斷題。原文第一段說“Astronomers know the dates of eclipses……”，由此可知，日食發(fā)生的日期可以推測出。

　　3.選D.本題為主要細節(jié)題。從第三段可知，日偏食發(fā)生后，雙方士兵以為天神發(fā)怒了，“So they stopped fighting,and ended their long war.”，所以D選項是戰(zhàn)爭結(jié)束的原因。

　　4.選C.本題為文章細節(jié)正誤題。第四段說“It appears to be bigger than any other star.That is because it is near us;but the other stars are far away.”，由此可知他星球看上去比太陽小是因為它們離我們很遙遠。
