语法重点:含情态动词的被动语态
含情态动词的被动语态用来说明某个被动性动作所反映出的感情和态度。初中阶段的常见情态动词有:can, may , need , must , shuld等。 谓语部分含有情态动词的被动语态的构成是:情态动词+be+过去分词
肯定句:主语+ 情态动词+be+动词过去分词.否定句:主语+情态动词+nt+ be+动词过去分词.一般疑问句:情态动词+ 主语+ be+ 动词过去分词?特殊疑问句:特殊疑问句+情态动词(+主语)+be+ 过去分词?
(一)将主动语态的宾语变成被动语态的主语。(二)将含情态动词的主动句式变成被动句式,即: “情态动词+动词原形”变成“情态动词+be+过去分词”,然后再在其后加“by+主动句中的主语(人称代词用宾格)”。by短语也可省略。请看下列各句:
Yu shuld finish yur hmewrk first. Yur hmewrk shuld be finished (by yu) first. Yu can take this magazine hme. This magazine can be taken hme (by yu).
含情态动词的疑问句、否定句的变化均需借助于情态动词完成。 一般疑问句: 直接将被动语态的陈述句中的情态 动词提前。
Must this task be finished at nce?这项任务必须立即完成吗?
注意: 含情态动词的被动语态的一般疑问句的回答,应保留原情态动词,但must表“必须”时,其否定回答应用needn’t;need表“必要”时,其肯定回答应用must。如:
--- Must my exercise bk be handed in nw? 我的练习本必须现在上交吗? --- Yes, it must. 是的,必须现在上交。 (N, it needn’t. 不,不必现在上交。)
2. 特殊疑问句: 由特殊疑问词加上被动语态的 一般疑问句构成。
When must this task be finished?这项任务必须在什么时候完成?
3. 否定句: 在情态动词后面加上nt或never即可, 但must表“必要” 时否定式为needn’t。
This task needn’t be finished at nce.这项任务没必要立即完成。
4. 反意疑问句: 借助情态动词构成附加疑问部分。 如: This bridge can be built next year, can’t it? 这座桥明年能建成,是吗?
