每周一練：虛擬語氣在名詞從句中

虛擬語氣在名詞從句中

    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。）

注意1：insist / suggest 各有兩種意思，要用不同的語氣

Insist ①表示“堅決要求”時，用虛擬形式，即should + do;

Insist ②表示“堅稱，堅持說”時，用陳述語氣，表示事實。

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.我堅持認為他是對的。

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使用虛擬語氣，表示“可惜…；….就好了；悔不該…；但愿…。”

I wish I knew the key to the answer.

I wish I were ten years younger.

I wish that I had gone to the football match last week.

I wish that you had been here yesterday.

He wishes that we would visit the old school.

How I wish these boys would be quiet.

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

      If only I had arrived in time! 我要是能及時來，那該多好啊！

      If only she had not driven so fast. 她要是沒開那么快該多好啊。

2、would rather+從句　謂語用過去時來表示現在或將來。其意為“寧愿……,還是…… 好些”“一個人寧愿另一個人做某事”。引導從句的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)
