3、語從句 。that在引導(dǎo)表語從句時(shí)無詞義，而whether 有詞義，意為、“是否”。這時(shí)主句的主語常常是些抽象名詞，如question（問題 ），trouble（麻煩），problem （問題 ），result （ 結(jié)果 ） ，chance （可能性 ），suggestion （建議 ），idea（想 法），reason （理由）等。表語從句對主句主語進(jìn)行說明、解釋，使主語的例如： The trouble is （that ） she has lost his mon ey.

That's what he is worryi ng about.問題是我們哪一個(gè)應(yīng)該去。問題是誰能做這項(xiàng)工作。那就是他在擔(dān)心的事。 That's what we should do.那是我們應(yīng)該做的。由關(guān)系副詞引導(dǎo)的表語從句。關(guān)系副詞 when, where, how, why除在句子起連接作用外，在從句中還充當(dāng)時(shí)間，地點(diǎn)，方式或原因狀語，本身具有詞義。例

6、如：Go and get your coat. It's where you left it.去把雨衣拿來。就在你原來放的地方。 I had n either a rain coat nor an umbrella.

9、tomorrow.Right: The questi on is why he cried yesterday.一致。D. that在表語從句中不可以省掉。基本用法表語從句只能置于主句之后，而主句的動詞只能是聯(lián)系動詞。名詞性從句在 be 等系動詞后作表語時(shí)被稱為表語從句例 口： The problem is how we can get the things we n eed.問題是我們怎樣能弄到我們需要的東西。（how 在表語從句中充當(dāng)方式狀語） The scissors are not what I need.這把剪刀不是我所需要的。（what 在表語從句中充當(dāng)賓語 ） What I to
