動詞的語態(tài)
一.概念:
動詞的語態(tài)是動詞的一種形式,表示主語和謂語之間語法或語義的關(guān)系.英語的語態(tài)有兩種:主動語態(tài)和被動語態(tài).主動語態(tài)用于主動句,表示主語是動作的執(zhí)行者.被動語態(tài)用于被動句,表示主語是動作的承受者.主動語態(tài)的構(gòu)成方式與動詞時態(tài)相同,而被動語態(tài)由 助動詞be+過去分詞 構(gòu)成,有人稱,數(shù),時態(tài)的變化.
一. 相關(guān)知識點精講
1. let 的用法
1)當let后只有一個單音節(jié)動詞,變被動語態(tài)時,可用不帶to 的不定式。例如:
They let the strange go.他們放陌生人走了。
---> The strange was let go.
2)當let 后賓補較長時,let 通常不用被動語態(tài),而用allow或permit 代替。例如:
The nurse let me go to see my classmate in the hospital. 那護士讓我去探望住院的同學。
----> I was allowed / permitted to see my classmate in the hospital.
2.短語動詞的被動語態(tài)
短語動詞是一個整體,不可丟掉后面的介詞或副詞。例如:
My sister will be taken care of by Grandma. 我妹妹由奶奶照顧。
Such a thing has never been heard of before. 這樣的事聞所未聞。
3. 表示"據(jù)說"或"相信" 的詞組,基本上由believe, consider, declare, expect, feel , report, say, see, suppose, think, understand等組成。例如:
It is said that… 據(jù)說
It is reported that… 據(jù)報道
It is believed that… 大家相信
It is hoped that… 大家希望
It is well known that… 眾所周知
It is thought that… 大家認為
It is suggested that… 據(jù)建議
It is taken granted that… 被視為當然
It has been decided that… 大家決定
It must be remember that… 務(wù)必記住的是
