中考中出現(xiàn)頻率較高的知識(shí)點(diǎn)：
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(yǔ)；“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(shuō)：“別說(shuō)話(huà)了，讓我們開(kāi)始上課。”
We have kept doing our homework for a long time. Let’s stop to listen to music. 我們做家庭作業(yè)很長(zhǎng)時(shí)間了，讓我們停下來(lái)聽(tīng)聽(tīng)音樂(lè)。
2.forget to do sth.和forget doing sth. (remember to do sth. 和remember doing sth.)
“forget to do sth.”表示將來(lái)不要忘記做某事，談的是未來(lái)的事情；“forget doing sth.”表示忘記過(guò)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(shuō)：“不要忘記做家庭作業(yè)。”
“I’m sorry. I forgot doing my homework. May I hand it in this afternoon, Mr. Chen?” said Li Ming.
李明說(shuō)：“對(duì)不起，我忘記做家庭作業(yè)了。我今天下午交好嗎，陳老師？”
3.have sth. done.（過(guò)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。
4. 感官動(dòng)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(jiàn)某人（經(jīng)常）做某事 和see sb. doing sth.看見(jiàn)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(jiàn)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(shí)候，我看見(jiàn)他正在那里畫(huà)畫(huà)。
5. 在主動(dòng)語(yǔ)態(tài)中，感官動(dòng)詞(see, hear, feel, watch等)和使役動(dòng)詞(make, have, let等)要求接不帶to的不定式做賓語(yǔ)補(bǔ)足語(yǔ)，而在被動(dòng)語(yǔ)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(tīng)說(shuō)她罵人了。
6．常用的幾個(gè)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(zhǎng)時(shí)間。
It is/was +形容詞+(for sb.) +to do sth. 做某事（對(duì)某人來(lái)說(shuō)）怎么樣。
7. 介詞后面一般接動(dòng)名詞。同學(xué)們要特別注意介詞to和不定式符號(hào)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)
8. 現(xiàn)在分詞和過(guò)去分詞做定語(yǔ)的區(qū)別
A. 現(xiàn)在分詞含有正在進(jìn)行的意思，而過(guò)去分詞含有被動(dòng)或者已經(jīng)完成的意思，如：
a developing country 發(fā)展中國(guó)家 a developed country 發(fā)達(dá)國(guó)家
boiling water 正在沸騰的水(一般情況下水溫為100℃) boiled water 開(kāi)水（已經(jīng)燒開(kāi)的水，水溫可以依然很高，也可以是涼白開(kāi)）
a boy named Jim 一個(gè)叫Jim的男孩
B. 有些動(dòng)詞的現(xiàn)在分詞和過(guò)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(lái)說(shuō)明事物的特征；他們的-ed形式表示被動(dòng)的意思，用來(lái)說(shuō)明人的情況。
I am interested in this interesting story. 我對(duì)這個(gè)有趣的故事感興趣。
I am moved at the moving sight. 我被這動(dòng)人的情景感動(dòng)了。
They were amazed at the amazing facts. 他們對(duì)那些令人驚異的事實(shí)感到驚奇。
