2016年职称英语卫生类语法辅导：特殊句型

特殊句型：

1.祈使句。祈使句后一般加上will you或won't you构成反义疑问句，用will you多表示“请求”，用won't you多表示提醒对方注意。例如：

let引导的祈使句有两种情况：①let's---，后的反义疑问句用shall we或shan't we。如：Let's go home, shan't we? 回家吧，好吗？②let us/me--- 后的反义疑问句用will you或won't you。如：let me have a try, won't you?

其他祈使句都用will you或won't you回答。

2.反意疑问句的陈述部分含有由un-, im-, in-, dis-, 等否定意义的前缀构成的词语时，陈述部分要视为肯定含义，问句部分用否定形式。①Your father is unhappy, isn't he? 不能用is he?②The man is dishonest, isn't he? 不能用is he?③It is impossible to learn English without remembering more words, isn't it?不能用is it ?

3.反意疑问句的陈述部分带有little, few, never, hardly, seldom，not,no,nobody,nothing, none, neither等否定意义的词时，问句部分用肯定式。如：①She never tells a lie, does she? 不用doesn't she?②He was seldom late, was he?不用wasn't he?
