题目内容
7.---Who _______ from Canada?---Nancy ________.( )| A. | are come; do | B. | is come; does | C. | comes; does | D. | are; is |
分析 --谁来自加拿大?
--Nancy.
解答 答案:C.
根据Who _______ from Canada,可知这里who作主语,who作主语的时候,后面的谓语动词应该用单数形式,句子叙述一件事实,所以时态应该用一般现在时,这里不含有被动的关系,所以be动词不能和动词原形放在一起.含有实义动词,主语为三单,故答语用助动词does.故选:C.
点评 本题考查动词的第三人称单数形式,解决此类问题的关键是掌握动词第三人称单数形式的变化规律,在不同的语言环境中达到熟练的运用.
