代詞it、one、that的用法與區別
One泛指,指代前面提到的那類人或物,用于指代可數名詞,相當于a+名詞單數,其復數形式ones前一般要有定語,否則就要用some.
That(those復數)即可指代不可數名詞,表特指,相當于the+名詞,后面經常與介詞修飾語連用。?It指代上文出現的名詞,表示同類同物,另外還可表示時間、距離、天氣、還可指代人稱代詞,表示性別身份不明,可作形式主語,形式賓語,引導強調句式以及一些固定搭配,如:get?it,?catch?it,?make?it.
例如:①?I?have?lost?my?watch.?I?think?I?must?buy?one.我丟了只表,我想我必須再買一只。(代指上文指到的同類事物,但不指同一個)
②?Where?is?my?pen??Have?you?seen?it?
我的鋼筆不知弄到哪去了,你見了嗎?(代指上文提到的同一事物)?③?The?land?of?China?is?larger?than?that?of?America.
④?Tome?has?a?red?pen?and?a?blue?one?(或two?blue?ones)
⑤?He?has?no?child,?and?he?wants?toadopt?one?(或?some)

用固定的情態動詞表示的虛擬語氣
1. should +動詞原形(有時省略should)
(1)用在動詞如advise, command, demand, desire, insist, order, propose, recommend, request, require, suggest, urge等后的賓語從句中。例如:
1)They requested that we (should) send a delegation to their country.
2)She urged that he write and accept the post.
(2)用在it is suggested, it is desired, it is required, it was ordered, it was proposed, it has been decided, it is necessary (essential, imperative, important, desirable) that等引出的主語從句中。例如:
1)It is desired that we (should) get everything ready by tonight.
2)It is necessary that the teacher (should) have a thorough knowledge of the subject he teaches.
(3)用在suggestion, motion, proposal, order, recommendation, plan, idea, requirement等引起的表語從句和同位語從句
例如:He put his coat over the child lest he should catch cold.

條件狀語從句
引導詞:if(如果),unless(除非),if only(只要,但愿),only if(只有),in case(萬一),suppose/supposing(that)
(假設),provided/providing(that)(只要,假若),on condition that(要是,在。。。條件下),so/as long as(只要),(let"s/let us)say(假設)
方式狀語從句
引導詞:as(像。。。一樣,正如。。。),as if/as though(好像,宛如)
注意:1、固定句型A is to B what C is to D.意為“A對B而言正如C對D一樣”。
2、as if, as though引導的從句若與事實相反,用虛擬語氣;若與事實相符,不用虛擬語氣。
讓步狀語從句
引導詞:though/although/as(雖然,盡管),even if/though(即使,盡管),whether/no matter whether...or(not)
(不管。。。是否,不管是。。。還是)wh-ever/no matter wh-(無論。。。)
注意:(1)though,although,as的區別
A、Though,although的主句中可以用yet, still, nevertheless,但不可使用but。
B、though引導的從句可以倒裝,也可以不倒裝;as引導的從句必須倒裝;although引導的從句不能倒裝。
其結構為:形容詞/分詞/副詞/動詞原形/名詞(無冠詞)+as/though+主語+謂語……
(2)though可用作副詞,放在句末,意為“不過,但是”。Although無此用法。
(3)某些短語也引導讓步的從句或短語,意為“盡管”,如:in spite of the fact that, despite the fact that, regardless of(the fact that)

一、不定式做主語:
1、不定式做主語一般表示具體的某次動作。動名詞doing表示習慣的,經常的動作。
e.g:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(對等)
注:1).不定式作主語時,謂語用單數
2).當主語較長,謂語較短時,常用it做形式主語,而將不定式放到謂語的后面。
it做形式主語,不定式放在謂語動詞之后常用于下列結構中:
(1)Itis/was+adj.+…
(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,但possible可以用不定式作真實主語,而probable不能用不定式作真實主語。
Itisprobableforhimtocometothemeeting.(錯)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
