一、不定式做主語(yǔ)：
1、不定式做主語(yǔ)一般表示具體的某次動(dòng)作。===動(dòng)名詞doing 表示習(xí)慣的'，經(jīng)常的動(dòng)作。
e.g: To finish the building in a month is difficult.
To do such things is foolish.
To see is to believe. (對(duì)等)
注: 1). 不定式作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)
2). 當(dāng)主語(yǔ)較長(zhǎng)，謂語(yǔ)較短時(shí)，常用it做形式主語(yǔ)，而將不定式放到謂語(yǔ)的后面。
it做形式主語(yǔ)，不定式放在謂語(yǔ)動(dòng)詞之后常用于下列結(jié)構(gòu)中：
(1)It is/was +adj.+of sb. to do…
(2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary
(3) it is +a +名詞+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do
It takes (sb.) some time / courage / patience …to do…
It requires courage / patience / hard work… to do…
注意: probable 和 possible 均可作表語(yǔ)，但possible可以用不定式作真實(shí)主語(yǔ)， 而probable不能用不定式作真實(shí)主語(yǔ)。
It is probable for him to come to the meeting.(錯(cuò))
It is possible for him to come to the meeting.
It is possible / probable that he will come to the meeting.
二、不定式做表語(yǔ)
主語(yǔ)是以aim duty hope idea intention plan job suggestion wish purpose task 等為中心詞的名詞詞組 或以 what 引導(dǎo)的名詞性從句表示，后面的不定式說(shuō)明其內(nèi)容, 不定式作表語(yǔ)常表示將來(lái)或現(xiàn)在的動(dòng)作或狀態(tài)。
eg :My idea is to climb the mountain from the north.
Your mistake was not to write that letter.
What I would suggest is to start work at once.

核心單詞
1. persuade
vt.說(shuō)服;勸服;使相信(同convince)
常用結(jié)構(gòu)：
persuade sb. of sth. 使某人相信某事
persuade sb. to do sth. 說(shuō)服某人做某事
persuade sb. into doing sth. 說(shuō)服某人做某事
persuade sb. out of doing sth. 說(shuō)服某人不要做某事
persuade sb. that-clause 使某人相信……
聯(lián)想拓展
talk sb. into/out of doing sth.=reason sb. into/out of doing sth.說(shuō)服某人做/不做某事
trick sb. into/out of doing sth. 誘使某人做/不做某事
urge sb. into/out of doing sth. 慫恿某人做/不做某事
易混辨析
advise/persuade
advise 強(qiáng)調(diào)"勸告，建議"的動(dòng)作，不注重結(jié)果;而persuade強(qiáng)調(diào)"已經(jīng)說(shuō)服"，重在結(jié)果。用法上：advise可跟v.-ing形式作賓語(yǔ)，也可以接that-clause (that sb. should do),而persuade則不能。
I persuaded him of its truth. 我使他相信這是真的。
We will persuade him to take the medicine.
我們將說(shuō)服他把藥吃下去。
We persuaded her into taking the job.
我們說(shuō)服她接受了這份工作。

另外，finally還可用在列舉事項(xiàng)時(shí)，引出最后一個(gè)內(nèi)容，相當(dāng)于lastly。 Firstly, we should make a plan; secondly, we should carry it out; finally we should make a conclu- sion.

-- Are we on time? 我們準(zhǔn)時(shí)嗎? -- I'm afraid not. 恐怕不準(zhǔn)時(shí)。I'm afraid you'll get caught in the rain.
