题目内容
14.The geography teacher said that nearly three quarters of the earthis covered (cover) with water.分析 地理老师说地球的几乎四分之三是由水覆盖的.
解答 答案:is covered.首先地球的几乎四分之三是由水覆盖的是客观真理,用一般现在时,再者地球是被水覆盖的,earth是cover的动作承受者,用被动语态,一般现在时的被动语态是am/is/are+过去分词,主语是the earth 第三人称单数,故用is.cover的过去分词是covered,故答案是is covered.
点评 如果是表示客观事实和普遍真理永远用一般现在时.
