動詞的語態(tài)
動詞的語態(tài)---表示謂語與主語之間的關(guān)系的動詞形式叫做語態(tài)，分為主動語態(tài)和被動語態(tài)。
主動語態(tài)表示主語是動作的執(zhí)行者,被動語態(tài)表示主語是動作的承受者
一、被動語態(tài)
結(jié)構(gòu):1.行為動詞的被動語態(tài): 助動詞be + 及物動詞的過去分詞.
be有人稱.時態(tài).數(shù)的變化,其變化規(guī)則與be作為連系動詞時完全一樣.
一般現(xiàn)在時 am/is/are+及物動詞的過去分詞 一般過去時 was/were +及物動詞的過去分詞
一般將來時 will +be +及物動詞的過去分詞 現(xiàn)在完成時 have/has+been+及物動詞的過去分詞
2.情態(tài)動詞的被動語態(tài): 情態(tài)動詞 + be +及物動詞的過去分詞
否定式:是在助動詞 be 或情態(tài)動詞后加not構(gòu)成
疑問式:是把上述助動詞或情態(tài)動詞提到主語之前,句尾加問號構(gòu)成.
用法: 1.不知道動作的執(zhí)行者是誰,或沒有必要或不想指出誰是動作的執(zhí)行者.
eg. The window was broken yesterday. Is English taught in your school? 2.強(qiáng)調(diào)或突出動作的承受者,此時如想同時指出動作的執(zhí)行者,可用“by +動作執(zhí)行者(賓格)來表示.
eg.The red dress was made by her mother. The letter must be written by me.
注 意點： 1.只有及物動詞能構(gòu)成被動語態(tài), 不及物動詞不能構(gòu)成被動語態(tài).
2.某些不及物動詞與介詞.副詞搭配構(gòu)成短語動詞,帶有賓語時,則有了動作的承受者,這時應(yīng)把它們看作一個整體,變?yōu)楸粍诱Z態(tài),不能丟掉其中的介詞,常用的有l(wèi)ook after,take care of,cut down, laugh at,talk about,turn on等 eg.Catherine always takes care of the little girl.→The little girl is always taken care of by Carherine.
3.有些動詞短語本身即是被動語態(tài)的形式, 不要再加by 短語,常用的有
be covered with be surprised at be interested in be worried about be made of/from be known to
4.某些動詞形式是主動語態(tài),但含有被動的意思. eg. This dictionary sells well.
This kind of car drives fast. The woolen sweater costs $ 88.
5.主動語態(tài)與被動語態(tài)的相互變化關(guān)系
主動句: 主語 + 謂語 + 賓語(動作執(zhí)行者) (動作承受者)
被動句: 主語 +謂語動詞的被動形式+ by + 動作執(zhí)行者 (動作承受者)
1）主動句如何變?yōu)楸粍泳?/p>
a.找到動作的承受者(常為主動句的賓語)作被動句的主語.b.找到謂語變?yōu)閎e + 過去分詞的結(jié)構(gòu).
c.找到動作的執(zhí)行者(常為主動句的主語)作 by 的賓語.若不必指出動作的執(zhí)行者,可省去 by 短語. d.確定be動詞的時態(tài).數(shù). 例如: She makes the beautiful kites.
The beautiful kites are made by her. (被動句)
2）被動句如何變?yōu)橹鲃泳? a.找到動作的執(zhí)行者(常為被動句的賓語)作主動句的主語.
b.找到be+過去分詞結(jié)構(gòu)還原為及物動詞原形.
c.找到動作的承受者(常為被動句的主語)作主動句的賓語.
d.確定及物動詞的時態(tài).數(shù)(注意)在以上轉(zhuǎn)換中,代詞作主語用主格, 代詞作賓語用賓格.
6.主動語態(tài)中有些動詞如:make,see,listen, watch,feel后常跟不帶to的動詞不定式作賓語補(bǔ)足語,變?yōu)楸粍诱Z態(tài)要帶上to
He made the boy work for him. →The boy was made to work for him.
7.主動語態(tài)中若有雙賓語,變?yōu)楸粍诱Z態(tài)時, 通常把指人的間接賓語變?yōu)楸粍诱Z態(tài)的主語. His uncle gave him a dictionary yesterday.→He was given a dictionary by his uncle yesterday.
