题目内容
6.─There's too much salt in the Chinese diet.─So there is.The WHO says only 1.5 grams of salt ______ for each man every day.( )
| A. | is needed | B. | is needing | C. | will need | D. | has needed |
分析 --中国饮食中有太多的盐.─的确如此.世界卫生组织说是每个人每天只需要1.5克盐.
解答 答案:A 根据…salt ______ for each man every day.可知主语salt是动作的承受者,与动词need构成被动关系,应该用被动语态.根据时间状语every day,可知讲述的是现在的情况,应该用一般现在时态.一般现在时的被动语态的构成:am/is/are+及物动词的过去分词.主语salt,是第三人称单数,所以应该是is needed,故选:A.
点评 主要考查被动语态,当句子的主语是动作的承受者时,应该用被动语态,本题考查的是一般现在时态的被动语态.一定注意其构成形式,一般现在时的被动语态的构成:am/is/are+及物动词的过去分词.
