  你不知道我有多着急!

  (3)wh­连接词引导的定语从句和wh­连接词引导的同位语从句的区别

同位语从句 定语从句 作成分,起连接作用,不可省略;有自己的含义,但是与先行词之间无关;所引导的句子对名词加以解释说明,且名词为抽象名词,如:

I have no idea when she will be back.

我不知道她将什么时候回来。

(句中的when与idea毫无意义上的关联,其意思是"什么时候",因此是同位语从句。) 作成分,起连接作用;没有自己的含义,但是代替先行词在从句中作成分。不可省略, 如:

I still remember the day when I first came to Beijing.

我还记得我第一次来北京的那天。(句中的when相当于"on that day",它没有疑问词"什么时候"的意义,是定语从句。)   即时演练2

  ⑤I have no idea who I will turn to (我将向谁求助) if I am in trouble.

  ⑥I have no idea what the boy is doing (那个男孩正在做什么) in the next room now.

  4.同位语从句的几种特殊情况

  (1)同位语从句的隔离现象

  当主句的谓语较短,而同位语从句较长时,同位语从句常后置。

  The fact remains that he accepted the money.

  他收了那笔钱的事实依然存在。

  An idea occurred to him that he might go there by air.

  他突然想起他可以乘飞机去那里。

  (2)名词doubt后同位语从句引导词的选择

  在名词doubt后的同位语从句用whether引导;在no doubt之后的同位语从句用that引导。

  We have some doubt whether they can come on time.

  我们怀疑他们是否能准时来。

  There is no doubt that he will keep his promise.

  毫无疑问他会守信的。

  (3)同位语从句中的虚拟语气

  在suggestion, advice, request, order等表示"建议;命令;要求"的名词后,同位语从句中的谓语动词通常用"should +动词原形"的虚拟语气结构,句中的should可以省略。

  Our teacher gave us some advice how we (should) use the computer.

  老师给我们提出了一些如何使用电脑的建议。
