大学英语 单选题6.He ( ) smoking,but a year ago he smoked 100 cigare
6.He ( ) smoking,but a year ago he smoked 100 cigarettes a week.
A has given up
B gave up
C had given up
D gives up
正解 A 后面半句说“但是一年前他每星期都抽100支烟啊”,所以以前抽烟 现在就是戒掉了 ,强调现在的结果 所以选择现在完成时,B过去时不对,过去戒烟又抽烟,究竟是要戒还是抽?C不对 过去完成时是发生在过去的过去,这有一个过去是抽眼,如果过去完成,2个过去,抽烟前戒烟,那能叫戒吗?D一般现在时不对,一般现在时说明习惯性的动作,习惯戒烟?没事就戒烟?不可能吧
Let’s go to school,( ) we?
A will
B shall
C can
D should
正解 B Let’s 必需用shall we ,因为包括说话者在内 Let us用will you,不包括说话者在内
题目意思:我们去学校,好吗
You don’t have to ring her up; she ( ) be at home,for I hear she has gone abroad.
A can’t
B may not
C must not
D won't
选择 A 这是情态用词的考查 在表示猜测的时候,非常肯定使用must ,否定形式用can't,不太肯定用may 或者 might ,否定用may not might not,只所以不选择C 是因为后面这个人猜测他不在是知道原因的
题目意思:你不用打电话给她了,她不可能在家的,因为我听说她出国了
“Must we hand in the papers this week?” “No,you ( ) .”
A must not
B may not
C needn’t
D can't
正解 C must在这用途是表示义务责任,意思“必须” ,回答不必就用,needn't,don't have to
题目意思:我们这个星期必须交论文吗?不,不必.
There’s something wrong,( ) there?
A are not
B are
C isn’t
D is
正解 C There's=There is...所以用is进行反问
这是一个肯定句,所以反问用否定形式.
题目意思:有什么不对劲的吗,是吗?
觉得可以请采纳.
能为你回答问题是件我也很高兴的事情
