The battery appears to have run down.这组电池好像已经用完了。(to have run down发生在appears所表示的时间之前)
但在下面句子中,动词不定式表示“动作没有完成”:
We were to have met at ten.我们本来是约定十点钟见面的。(结果未见面)
动词不定式进行式的用法
动词不定式进行式表示动作正在进行,与谓语动词表示的动作同时发生。如:
He see ms to be recovering.他看来在康复。
When he came in,I happened to be lying on the bed,reading.他进来的时候,我碰巧正躺在床上看书。
动词不定式的`被动语态
动词不定式有两种被动语态形式:
一般式to be written
完成式to have been written
例:
The next thing to be done is to carry away the earth.下-步要做的事是把土运走。
No harm seems to have been done.似乎并没有造成损害。
分裂不定式
有时在不定式符号“to”和动词原形之间插入一个副词,这种现象叫做分裂不定式(split infinitive)。插入动词不定式的副词,习惯上往往与不定式动词连在一起。如:
He likes to half close his eyes.他喜欢半闭着眼睛。
Our object is to further cement friendly relations between the two countries.我们的目的是进一步加强两国之间的友好关系。
At first he wasn't interested in bookkeeping,but later he began to actually like it.起初他对会计工作没有兴趣,但到后来倒喜欢起它来了
篇5:动词的语态语法讲解及练习题
一、动词的语态语法讲解
1. let 的用法
1)当let后只有一个单音节动词,变被动语态时,可用不带to 的不定式。例如:
They let the strange go.他们放陌生人走了。
---> The strange was let go.
2)当let 后宾补较长时,let 通常不用被动语态,而用allow或permit 代替。例如:
The nurse let me go to see my classmate in the hospital. 那护士让我去探望住院的同学。
----> I was allowed / permitted to see my classmate in the hospital.
2.短语动词的被动语态
短语动词是一个整体,不可丢掉后面的介词或副词。例如:
My sister will be taken care of by Grandma. 我妹妹由奶奶照顾。
Such a thing has never been heard of before. 这样的事闻所未闻。
3. 表示“据说”或“相信” 的词组,基本上由believe, consider, declare, expect, feel , report, say, see, suppose, think, understand等组成。例如:
It is said that… 据说
It is reported that… 据报道
It is believed that… 大家相信
It is hoped that… 大家希望
It is well known that… 众所周知
It is thought that… 大家认为
It is suggested that… 据建议
It is taken granted that… 被视为当然
It has been decided that… 大家决定
It must be remember that… 务必记住的是
4. 不用被动语态的情况
1) 不及物动词或不及物动词短语,如appear, die disappear, end(vi. 结束), fail, happen, last, lie, remain, sit, spread, stand, break out, come true, fall asleep, keep silence, lose heart, take place等没有无被动语态。例如:
After the fire, very little remained of my house. 大火过后,我家烧得所剩无几。
比较:rise, fall, happen是不及物动词;raise, seat是及物动词。
要想正确地使用被动语态,就须注意哪些动词是及物的,哪些是不及物的。特别是一词多义的动词往往有两种用法。解决这一问题唯有在学习过程中多留意积累。
2) 不能用于被动语态的及物动词或动词短语,如fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to等。例如:
This key just fits the lock. 这把钥匙只配这把锁。
Your story agrees with what had already been heard. 你说的与我们听说的一致。
3) 系动词无被动语态,如appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn等。例如:It sounds good. 听上去不错。
4) 带同源宾语的及物动词如die/death, dream/dream, live/life等,以及反身代词,相互代词,不能用于被动语态。例如:
