英語知識點(diǎn)
1.在由suggest, demand, require, request, insist, order, command, propose等表示建議、請求、命令、愿望等動詞或其同根詞引出的名詞從句中，名詞從句虛擬句的謂語變化的形式只有一條規(guī)律——名詞從句虛擬句無論其主句的謂語動詞時何種形式，從句的謂語形式均為should+動詞原形，其中should可以省去。（特別提醒：不是用would,而是用should。）
|
常見的這類動詞有: ask要求, advise, beg, suggest建議, command命令, demand要求，request請求, insist, require要求, order下令, propose, advice, recommend, intend, prefer寧愿, permit, persuade, expect, decide決定, instruct, object, determine, urge, appoint等等
|

|
|
在It is/was +上述動詞的-ed形式+that從句中
|
It is suggested by the doctor that I should give up smoking. 醫(yī)生建議我戒煙。
|
|
當(dāng)上述動詞以其名詞形式出現(xiàn)，并且被用作主語，引導(dǎo)一個表語從句或者同位語從句時
|
My suggestion is that we (should) set out tomorrow morning. 我建議我們明早動身。
The suggestion that the sports meeting (should) put off
|
|
在It is /was necessary, important等形容詞+that從句中，常見的這類形容詞有:necessary, important, essential, vital, advisable, urgent, desirable, natural, strange, imperative等
|
It is necessary that you should attend the meeting. 你有必要參加會議。
It is imperative that you arrive there in time. 你必須按時到達(dá)那兒。
|
|
在It is a pity (a shame, no wonder)+that從句中
|
It is a pity that you fail the exam.
It is no wonder he be late for class.
|
注意1：insist / suggest 各有兩種意思，要用不同的語氣
Insist ①表示“堅(jiān)決要求”時，用虛擬形式，即should + do;
Insist ②表示“堅(jiān)稱，堅(jiān)持說”時，用陳述語氣，表示事實(shí)。
Suggest ①表示“建議”時，用虛擬形式。
Suggest ②表示“表明、暗示”時，用陳述語氣。
I insisted that he was right.我堅(jiān)持認(rèn)為他是對的。
Your pale face suggests that you are ill.你蒼白的臉表明你病了。
注意2：It’s (high/right) time that… that從句要用虛擬語氣：謂語用過去時或should + do ，should不可略。It’s time that you left here.或It’s time that you should leave here.
2.wish 后面的賓語從句的謂語動詞應(yīng)使用虛擬語氣，表示“可惜…；….就好了；悔不該…；但愿…。”

二、其它句式
1、if only 意為：若是...那該多好啊; 真希望...; 只要, 只要...就好。表示含蓄的條件,這時主句要用虛擬語氣

2、would rather+從句 謂語用過去時來表示現(xiàn)在或?qū)�。其意�?ldquo;寧愿……,還是…… 好些”“一個人寧愿另一個人做某事”。引導(dǎo)從句的that常省略。過去的動作，謂語則用過去完成時。
John wants to see me today. I would rather he came tomorrow than today.
約翰今天想去看我。我寧愿他明天來看我而不是今天。(句中came不是表示過去而是表示將來)
