高考英語必考點：it的固定句式
育路網(wǎng)整理了高考英語必考點：it的固定句式，希望大家能認真復習這些必考點!
第一，it作形式主語的常見句型?
(1)it替代動詞不定式的常見句型為：?
①It+ be+ adj+ (for sb.) to do sth. ?
此處的形容詞通常為描述事件的形容詞：easy, difficult, hard, necessary, unnecessary, possible等。如：?
It is illegal for a teenager to drive a car without a license. ?
②It +be+ adj.+of sb. to do sth. ?
此處的形容詞通常為描述人的形容詞：kind, unkind, nice, rude, cruel等。如：?
It’s kind of you to help me with the problem. ?
(2)it替代動詞-ing的常見句型： ?
It’s no good/use doing...?
It’s (well) worth doing...
如：It’s no use crying over spilt milk. ?
(3)it替代從句的常見句型： ?
①It +be+n.+that從句?如：?
It is no secret that the president wants to have a second term in office.??
②It +be+adj.(important, necessary, surprising...)+that從句 ?
從句中的謂語動詞用"should+動詞原形"形式，且should可省略。如：?
It’s important that you should apologize to her for your rudeness.
③It +v.+sb.+that從句= It +be+ v-ing +that從句?如： ?
It worried me that she drove so fast.(= It was worrying that she drove so fast.) ?
④It+v.(+to sb.)+ that從句 ?
常用動詞或短語有appear, seem, come about, emerge, follow, chance, happen, occur, transpire, turn out, work out等。如： ?
It (so) happened/chanced that they were out.(= They happened/chanced to be out.) ?
⑤It +be+ v-ed +that從句 ?
常用動詞有say, report, think, believe, hope, expect, agree, accept, decide, determine, intend, plan, understand, know等。如： ?
It is said that the couple have gotten divorced.(=The couple are said to have gotten divorced.) ?
⑥It +be +v-ed + that...(should)...?
常用動詞有demand, request, require, order, suggest, advise, recommend等。如：?
It is suggested that they should begin with the third question.
第二，it除了作形式主語外，也可以作形式賓語，如動詞find, think, consider, feel, make等，這些詞后常用it作形式賓語，替代其后的動詞不定式或從句。此外，英語中動詞appreciate, enjoy, like, dislike, love, hate, prefer等之后，常用it作形式賓語，替代其后的when/if從句。如：?
I find it interesting to talk with her. 我覺得與她聊天很有趣。?
I think it possible that she would like to help you. 我認為她幫助你是有可能的。?
【典例1】
__is the sun that gives off light and heat, which makes __possible for plants to grow.?
A. It; it B. That; those ?
C. This; it D. This; them??
{錯因分析} 如果考生對it作形式賓語及含it的強調(diào)句型掌握得不牢固，就會造成誤選。
{解析} 分析句子結(jié)構(gòu)可知，第一空考查強調(diào)句型的基本結(jié)構(gòu)：it is/was+被強調(diào)部分+that+句子的其他部分，故用it;第二空用it作形式賓語，其真正的賓語是后面的動詞不定式。答案為A項。
【典例2】
To her joy, Della earned first the trust of her students and then ?__of her colleagues.?
A. that B. one?
C. ones D. those?
{錯因分析} 很多考生看到橫線后的of就錯誤地選擇了B、C項，沒有弄清句子要表達的意思。?
{解析} 句意：使她高興的是，Della首先贏得了她的學生的信任,然后又獲得了同事的信任。空后面的"of her colleagues"與前面的"of her students"是同樣的結(jié)構(gòu)，因此此空應(yīng)該選擇that來替代the trust，以避免重復。答案為A項。?
【典例3】
I’d appreciate __if you could let me know in advance whether or not you will come.(2014·陜西)
A. it B. you?
C. one D. this?
{錯因分析} 考生如果沒有掌握這個知識點"英語中動詞appreciate, enjoy, like, dislike, love, hate, prefer等之后，常用it+when/if從句"，在做此題時就很容易誤選選項。?
{解析} 句意：如果你能夠讓我提前知道你是否要來，我會非常感激。根據(jù)句子的結(jié)構(gòu)，此空在句中作形式賓語，而真正的賓語為if所引導的從句，故要用it。故答案為A。?
第三，含it的固定用法
forget it沒關(guān)系，休想，不必在意?
get it 明白了，理解了，知道了 ?
I can’t help it我沒辦法 ?
make it 獲得成功，幸免于難?
