求高手帮我解了这英语作业
Late in the afternoon, the boys put up their tent in the middle of a field. As soon as this was done, they cooked a meal over an open fire. They were all hungry and the food smelt good. After a wonderful meal, they told stories and sang songs by the camp fire. But some time later it began to rain. The boys felt tired so they put out the fire and crept into their tent. Their sleeping bags were warm and comfortable, so they all slept soundly. In the middle of the night, two boys woke up and began shouting. The tent was full of water! They all leapt out of their sleeping bags and hurried outside. It was raining heavily and they found that a stream had formed in the field. The stream wound its way across the field and then flowed right under their tent!

表时态动词看插图
动名词主要用法。
A.作句子的主语
句型 V-ing…+V…
例A:Smoking is a bad habit.
(吸烟是坏习惯。)
例B:taking exercise every morning helps make one healthy.
(每天早晨做运动有助于人的健康。)
例C:It isn't easy trying to please her.
(想办法讨好她是不容易的。)
解说 动名词作主语用时是属于第三人称单数,因此要取单数形式动词。例C是表示动名词也可用“It…”的句式来表达。
B.作主语补语
句型 S+be+V-ing…
例A:My favorite sport is swimming.
(我最喜爱的运动是游泳。)
例B:Her only desire is studying music.
(她的唯一的愿望就是学音乐。)
C.作直按宾语
句型 S+Vt. +V-ing
例A:I enjoy watching TV news after supper.
(晚饭后我喜爱看电视新闻。)
例B:You'd better stop smoking.
(你最好把烟戒掉了。)
例C:It began raining heavily when we got there.
(我们到达那里时,开始下起大雨来了。)
例D:I remember seeing her somewhere before.
(我记得以前在什么地方见过她。)
例E:Do you mind mailing this letter for me ?
(替我寄这封信你介意吗?)
解说 英语的Vt. 取直接宾语时,有的习惯上要取不定式,有的则要取动名词,有的则取不定式或动名词皆可,表达的意思大致相同,但是也有些表达的意思不相同,现分别介绍如下:
①Vt. +V-ing …(习惯上取动名词为直接宾语)(如例A、B)
admit(承认),advise(劝告),avoid(避免),consider(考虑),
escape(脱逃),finish(做完),keep (on) (持续),practice(练习),quit(停止),resist(抵抗),risk(冒险),stand(忍受——否定句),stop(停止),understand(了解),etc .
注:请注意下面两句表达上的差别:
例:He stopped smoking. (他停止吸烟了。)
例:He stopped to smoke. (他抽起烟来了。)
第二句是“He stopped doing something and began to smoke. ”的意思。
②Vt. +V-ing…/to V…(动名词或不定式皆可,表达的意思大致相同。)(如例C)
begin(开始),cease(停止),continue(继续),fear(恐惧),start(开始),etc.
③Vt. +V-ing…/to V…(可取动名词,也可取不定式,但表达的意思不相同或用法不相同。)(如例D)
dislike(不喜欢),forget(忘却),hate(讨厌;恨),like(喜欢),love(爱;喜欢),need(需要),remember(记得),try(尝试),want(需要),etc.
注:本项所说的表达意义不同或用法不同,请参考词典,这里仅以“remember,”和“want”为例提供参考例句如下:
I remember seeing her somewhere before.
(我记得以前在什么地方见过她。)
I remember to see her tomorrow.
(我会记得明天去看她。)
由上例可知“remember +V-ing…”是指“对过去所做过的事记得”的意思,而“remember +to V…”是指“对将来的某一件事会记得去做”的意思。
Do you want to paint to door?
(你要油漆门吗?—“want”的意思是“要,欲”)
The door wants painting.
(这一道门需要油漆了。—“want”的意思是“需要”,即“need”,而“painting”所表达的意思是“to be painted”。)
例E的“mind +V-ing…?”通常是指说话者要请对方“来做……”的意思,若是说话者自己要做而在征求对方的同意时则使用“mind +my +V-ing…”的句式。
例:Do you mind opening the windows?
(请你把窗打开,你介意吗?)
Certainly not. (当然不介意。)
例:Do you mind me [my] smoking ?
(你会介意我吸烟吗?)
No, please do. (不会的,请便。)
“mind +V-ing”也可用于表达否定。
例:I don't mind being found going out with him.
(我不在乎被人看到和他一同出去。)
D.作介词的宾语
句型prep. +V-ing…
例A:He drove away without saying good-by.
(他没说再见就开了车走了。)
例B:It is not easy to make a living by writing .
(靠写作谋生是不容易的。)
例C:It is polite to knock before entering a room.
=It is…before one enters a room.
(进入房间之前敲门是一种礼貌。)
解说 如例C,因“before”也可作连词用,所以动名词部分可改以从句来表达。其他如“after, since”也可以仿照例C来表达。
