2016年職稱英語考試衛(wèi)生類語法:特殊句型

字號:

1.祈使句。祈使句后一般加上will you或won't you構(gòu)成反義疑問句,用will you多表示“請求”,用won't you多表示提醒對方注意。例如:
    let引導(dǎo)的祈使句有兩種情況:①let's---,后的反義疑問句用shall we或shan't we。如:Let's go home, shan't we? 回家吧,好嗎?②let us/me--- 后的反義疑問句用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.反意疑問句的陳述部分含有由un-, im-, in-, dis-, 等否定意義的前綴構(gòu)成的詞語時,陳述部分要視為肯定含義,問句部分用否定形式。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.反意疑問句的陳述部分帶有l(wèi)ittle, few, never, hardly, seldom,not,no,nobody,nothing, none, neither等否定意義的詞時,問句部分用肯定式。如:①She never tells a lie, does she? 不用doesn't she?②He was seldom late, was he?不用wasn't he?
