語態(tài)有兩種:主動(dòng)語態(tài)和被動(dòng)語態(tài)。
主語是動(dòng)作的發(fā)出者為主動(dòng)語態(tài);主語是動(dòng)作的接受者為被動(dòng)語態(tài)。
(1)被動(dòng)語態(tài)
1) 被動(dòng)語態(tài)最基本的句型結(jié)構(gòu)是: be +及物動(dòng)詞過去分詞
2) 被動(dòng)語態(tài)中的謂語動(dòng)詞一定要是及物動(dòng)詞
因?yàn)楸粍?dòng)句中的主語是動(dòng)作的承受者,某些短語動(dòng)詞如look after, think of, take care of, work out, laugh at等,也可用于被動(dòng)語態(tài)。
The children were taken good care of by her.
【注意】
短語動(dòng)詞中的介詞或副詞變成被動(dòng)語態(tài)時(shí)不可遺漏。
3) 主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài)要加“to”的情況
若賓語補(bǔ)足語是不帶to 的不定式,變?yōu)楸粍?dòng)語態(tài)時(shí),該不定式前要加to。此類動(dòng)詞為感官動(dòng)詞,如:feel, hear, help, listen to, look at, make, observe, see, notice, watch等。例如:
The teacher made me go out of the classroom.
I was made to go out of the classroom (by the teacher).
4) 主動(dòng)形式表示被動(dòng)意義
如wash, clean, look, cut, sell, read, wear, feel, draw, write, sell等動(dòng)詞雖然用做主動(dòng)形式卻表示被動(dòng)的意義。例如:
The food tastes good.
3.非謂語動(dòng)詞
對非謂語動(dòng)詞的考點(diǎn)是:感官動(dòng)詞后不定式作賓語補(bǔ)足語和動(dòng)詞ing形式作賓語補(bǔ)足語的用法;一些特殊動(dòng)詞的動(dòng)詞不定式作賓語補(bǔ)足語時(shí)不帶to,但變?yōu)楸粍?dòng)語態(tài)時(shí)就要帶to;有些動(dòng)詞既可接不定式也可接動(dòng)詞ing形式作賓語,但表達(dá)的意思不同。這些都是歷年中考的重點(diǎn)。
(1)非謂語動(dòng)詞的形式
非謂語動(dòng)詞指的是在句中起名詞,形容詞或副詞作用的動(dòng)詞形式,而不是作謂語的動(dòng)詞形式。 動(dòng)詞的非謂語形式分為動(dòng)名詞,分詞,動(dòng)詞不定式。
(2)不定式作賓語補(bǔ)足語
Father will not allow us to play on the street.
(3)不定式作目的狀語
He ran so fast as to catch the first bus.
(4)用不定式和分詞作補(bǔ)足語都可以的動(dòng)詞
這樣的動(dòng)詞有感官動(dòng)詞如:see, hear, look, notice, observe, feel等,使役動(dòng)詞如:have, make, leave, keep, get等。接不定式表示動(dòng)作的完整性,真實(shí)性;+doing 表示動(dòng)作的連續(xù)性,進(jìn)行性。
I saw him work in the garden yesterday.
我看見他在花園里干活了。(強(qiáng)調(diào)我看見了這個(gè)事實(shí))
I saw him working in the garden yesterday.(強(qiáng)調(diào)我見他正干活這個(gè)動(dòng)作)
我見他正在花園里干活。
(5)用不帶to不定式的情況
使役動(dòng)詞如: let, have, make等和感官動(dòng)詞如: see, watch, hear, listen to, smell, feel, find 等后作賓補(bǔ),省略to。在被動(dòng)語態(tài)中則to不能省掉。
(6)接動(dòng)名詞與不定式意義不同
1) stop to do 停止,中斷做某事后去做另一件事。
stop doing 停止做某事。
2) forget to do 忘記要去做某事。 (未做)
forget doing 忘記做過某事! (已做)
3) remember to do 記得去做某事 (未做)
remember doing 記得做過某事 (已做)
4) try to do 努力,企圖做某事。
try doing 試驗(yàn),試著做某事。
5) go on to do 做了一件事后,接著做另一件事。
go on doing 繼續(xù)做原來做的事。
6) mean to do 打算、想
mean doing 意味著
4. 容易混淆的常用動(dòng)詞的辨析
