　　That's why I want you to work there. 那就是我要你在那兒工作的原因。

　　His first question was whether Mr. Smith had arrived yet.

　　他的第一個問題是史密斯先生到了沒有。

　　as if, as though, because也可用來引導(dǎo)表語從句。

　　She seems as if she had done a great thing. 她看起來好像做了一件大事。

　　It is because you eat too much. 那是因為你吃得太多了。

　　2. 虛擬語氣：表語從句

　　主語是idea, notion, proposal, suggestion, request等名詞時, 作表語從句的動詞為原形動詞或should+原形動詞。

　　My suggestion is that we (should) go and help him. 我的建議是我們應(yīng)該去幫助他。

　　Our only request is that this should be settled as soon as possible.

　　我們唯一的請求就是盡快解決這個問題。
