初三必看:中考英語高頻考點匯總
1.stop to do sth. 和stop doing sth.
“stop to do sth.” 表示停止做其它事情而去做“to do sth.”所表示的事情,可以將“to do sth.”理解成“stop”的目的狀語:“stop doing sth.”表示不做“doing sth.”所表示的事情。
例如:“Stop talking. Let's begin our class.”said the teacher. 老師說:“別說話了,讓我們開始上課。”
We have kept doing our homework for a long time. Let's stop to listen to music. 我們做家庭功課很長時間了,讓我們停下來聽聽音樂。
2.have sth. done.(過去分詞)(讓別人)做某事
例如:I had my hair cut yesterday afternoon. 我昨天下午理了發(fā)。
My computer can not work now. I must have it repaired. 我的電腦有故障了,我必須讓人修好它。
3.forget to do sth.和forget doing sth. (remember to do sth. 和remember doing sth.)
“forget to do sth.”表示將來不要忘記做某事,談的是未來的事情:“forget doing sth.”表示忘記過去應(yīng)該做的事情。
例如:“Don't forget to do your homework.”said the teacher before the class was over.
老師在下課前說:“不要忘記做家庭功課。”
“I'm sorry. I forgot doing my homework. May I hand it in this afternoon,Mr. Chen?”said Li Ming.
李明說:“對不起,我忘記做家庭功課了。我今天下午交好嗎,陳老師?”
4. 感官動詞后接不帶to的不定式或者現(xiàn)在分詞的區(qū)別
例如:see sb. do sth.看見某人(經(jīng)常)做某事 和see sb. doing sth.看見某人(正在)做某事
I often see him do exercise in the morning. 我經(jīng)常在早晨看見他鍛煉身體。
When I was walking in the park,I saw him drawing a picture there. 當(dāng)我在公園散步的時候,我看見他正在那里畫畫。
5. 介詞后面一般接動名詞。同學(xué)們要特別注意介詞to和不定式符號to的區(qū)別,例如下面的詞組一定要記清:
prefer doing sth. to doing sth. 喜歡做……不喜歡做……
look forward to doing sth. 期待/盼望做某事
make a contribution to doing sth. 為……做出貢獻(xiàn)
6. 在主動語態(tài)中,感官動詞(see,hear,feel,watch等)和使役動詞(make,have,let等)要求接不帶to的不定式做賓語補足語,而在被動語態(tài)里,不定式要帶上to.
例如:The boss often made the workers work 10 hours a day.
The workers were made to work 10 hours a day.
She was heard to use strong language. 聽說她罵人了。
7.常用的幾個和不定式有關(guān)的句型:
Why not do sth?為什么不做某事?
It takes/took sb. some time to do sth. 做某事花了某人多長時間。
It is/was +形容詞+(for sb.)+to do sth. 做某事(對某人來說)怎么樣。
8. 現(xiàn)在分詞和過去分詞做定語的區(qū)別
A. 現(xiàn)在分詞含有正在進(jìn)行的意思,而過去分詞含有被動或者已經(jīng)完成的意思,如:
a developing country 發(fā)展中國家 a developed country 發(fā)達(dá)國家
boiling water 正在沸騰的水(一般情況下水溫為100℃) boiled water 開水(已經(jīng)燒開的水,水溫可以依然很高,也可以是涼白開)
a boy named Jim 一個叫Jim的男孩
B. 有些動詞的現(xiàn)在分詞和過去分詞都具有形容詞特征,但是它們的意思有區(qū)別。它們的-ing形式往往用來說明事物的特征;他們的-ed形式表示被動的意思,用來說明人的情況。
I am interested in this interesting story. 我對這個有趣的故事感興趣。
I am moved at the moving sight. 我被這動人的情景感動了。
They were amazed at the amazing facts. 他們對那些令人驚異的事實感到驚奇。
