题目内容
6.-My father __________ free.He can't play with me.( )| A. | has | B. | is | C. | doesn't have | D. | isn't |
分析 我的爸爸没有时间,他不能和我玩耍.
解答 答案:D.结合He can't play with me可知爸爸没有时间,故用否定句,be free有空,主语my father,故is,故答案是D.
点评 简单地说否定句就是在动词后面加not,有is、am、are的句子会在这些词后面加not,I am (not) a boy.没有is、am、are的句子会在动词前加don't或者do not,I (don't)like basketball.
如果有must、may、can这类的词,在这类词后面加not,I can (not )walk.
