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:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(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)Itis/was+adj.+ofsb.todo…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名詞+todo...
Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo
Ittakes(sb.)sometime/courage/patience…todo…
Itrequirescourage/patience/hardwork…todo…
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)。
Itisprobableforhimtocometothemeeting.(錯(cuò))
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.

1、所謂雙重所有格就是指將 -’s 所有格與 of 所有格結(jié)合起來(lái)一起使用：
a friend of my father’s 我父親的一位朋友
a photo of Mr Smith’s 史密斯先生的一張照片
2、雙重所有格的使用場(chǎng)合：
①當(dāng)被修飾名詞前有指示代詞、疑問(wèn)代詞、不定代詞或數(shù)詞等限定詞時(shí)，一般要用雙重所有格：
I don’t like that big nose of David’s. 我不喜歡大衛(wèi)的那個(gè)大鼻子。
Which novel of Dickens’ are you referring to? 你談的是狄更斯的哪部小說(shuō)?
Some friends of my brother’s will come. 我兄弟的一些朋友要來(lái)。
【注】被雙重所有格修飾名詞前有指示代詞時(shí)，通常帶有一定的感情色彩(如贊賞、不滿、厭惡等)：
That little daughter of your cousin’s is really a dear. 你表哥的那個(gè)小女兒真是逗人愛(ài)。(表贊賞)
That daughter of your cousin’s is constantly complaining. 你表哥的那個(gè)女兒老是在報(bào)怨。(表厭惡)
另外，被雙重所有格修飾的名詞前可以用不定冠詞，但通常不用定冠詞：
可以說(shuō)：a poem of Shelly’s, a novel of Dickens’
不能說(shuō)：the poem of Shelly’s, the novel of Dickens’
②有時(shí)既可用雙重所有格也可用 of 所有格，但含義稍有差別。比較：
a photo of Mary’s 瑪麗收藏的一張照片
a photo of Mary 瑪麗照的一張照片
a criticism of William’s 威廉提出的批評(píng)
a criticism of William 對(duì)威廉的批評(píng)

It的用法
1、It除了代替人和物以外,還可以作形式主語(yǔ).而真正的主語(yǔ)(不定式、動(dòng)名詞或從句)則放于謂語(yǔ)或表語(yǔ)之后.
例如：It is nor easy to finish the work in two days.
然而有少數(shù)表語(yǔ)之后接動(dòng)名詞作真正的主語(yǔ).這些表語(yǔ)是：無(wú)助(no help)、無(wú)用(no use)、沒(méi)好處(no good);工作(hard work)、費(fèi)時(shí)(a waste of time)、又危險(xiǎn)(a danger).
例如：A、It is no use crying over spilt milk.
B、It is a waste of time waiting for him.
2、It還可以作形式賓語(yǔ).通常下列動(dòng)詞后面可接it作形式賓語(yǔ)：2f2tcjm(find,feel,think,take,consider,judge, make).
例如：A、He made it clear that he was not interested in this subject.
B、I think it no use arguing with him.
3、It用于強(qiáng)調(diào)句式.要強(qiáng)調(diào)句子的某一部分(主語(yǔ)、賓語(yǔ)、 狀語(yǔ)),可以把it當(dāng)作先行詞.這種句子的結(jié)構(gòu)是：It is(was)+ 被強(qiáng)調(diào)部分+that(who)+句子的其余部分.
例如：A、It iS Professor Lin who teaches us English—(強(qiáng)調(diào)主語(yǔ))
B、It was in Shanghai that l saw the film.—(強(qiáng)調(diào)狀語(yǔ))
C、It was in 1990 that I worked in the factory.(同上)
但要注意與定語(yǔ)從句的區(qū)別.
例如：D、It was 1990 when I worked in the factory.(定語(yǔ)從句)
在強(qiáng)調(diào)句式里,我們把強(qiáng)調(diào)結(jié)構(gòu)It is(was)…that除去,句子還很完整.如例句C.而例句D就不能.
