题目内容
19.-Can Mr Smith spend some time on the charity show?-If he ___,he will try his best to make it.( )
| A. | is invited | B. | will be invited | C. | invites | D. | invited |
分析 -史密斯先生可以在慈善演出上花些时间吗?
-如果他被邀请,他会尽最大努力做到的.
解答 答案:A
分析句子结构可知该句为含有if引导的条件状语从句的复合句,句中缺少从句的谓语动词,根据主句he will try his best to make it.为一般将来时态,依据"主将从现"原则可知从句为一般现在时态,又知从句的主语he 是谓语动词invite的承受者,二者形成被动关系,故确定为被动语态,故确定从句的谓语动词为一般现在时态的被动语态,其结构为:am/is/are+及物动词的过去分词.主语he是第三人称单数,助动词为is,invite的过去分词为invited,故填入is invited,故选A
点评 本题主要考查语态辨析,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
