1、try, mean, remember, forget, regret等動(dòng)詞后跟不定式或動(dòng)名詞意思不同。例如：
We must try to solve this problem.
我們必須設(shè)法解決這個(gè)問題。
We can try solving this problem in other ways.
我們可以試用另一些方法來解決這一問題。
I must remember to pay you for the ticket.
我一定要記住把電影票的錢支付給你（支付的動(dòng)作還沒有發(fā)生）。
I remember seeing you somewhere.
我記著在什么地方見過你（見的動(dòng)作已經(jīng)發(fā)生）。
2、demand, deserve, need, require, want等詞既可以要求動(dòng)詞＋-ing作賓語(yǔ)，也可以要求動(dòng)詞不定式的被動(dòng)式作賓語(yǔ)。例如：
John’s house in the country wants painting.
John’s house in the country wants to be painted.
這兩種結(jié)構(gòu)意義相同。
3、還有像go on, stop這類動(dòng)詞如果后接動(dòng)詞＋-ing則表示繼續(xù)（做某事）或停止（做某事）；而如果后接動(dòng)詞不定式則表示前面一個(gè)動(dòng)作已結(jié)束或停止，繼之做另一個(gè)動(dòng)作。例如：
The robot first reads the engineering drawing and then goes on to assemble the parts
according to the drawing.
機(jī)器人首先閱讀工程圖紙，然后根據(jù)圖紙安裝零部件。
Some students went on working on their examination when the bell rang.
當(dāng)鈴聲響的時(shí)候，一些學(xué)生還在繼續(xù)做考試題。
4、要求動(dòng)詞不定式做賓語(yǔ)補(bǔ)足語(yǔ)的動(dòng)詞有：feel, have, hear, let, listen to, look at, make, notice, observe, see和watch。在這些動(dòng)詞后面，做賓語(yǔ)補(bǔ)足語(yǔ)的動(dòng)詞不定式不帶to。例如：
I’ll try to get someone repair the recorder for you.
Electricity makes the motor run.
但是當(dāng)這些動(dòng)詞用于被動(dòng)語(yǔ)態(tài)時(shí)，后面的動(dòng)詞不定式則必須帶to。例如：
The motor is made to run by electricity.
We must try to solve this problem.
我們必須設(shè)法解決這個(gè)問題。
We can try solving this problem in other ways.
我們可以試用另一些方法來解決這一問題。
I must remember to pay you for the ticket.
我一定要記住把電影票的錢支付給你（支付的動(dòng)作還沒有發(fā)生）。
I remember seeing you somewhere.
我記著在什么地方見過你（見的動(dòng)作已經(jīng)發(fā)生）。
