表語從句的常見句型

表語從句位於主句系動詞之後，可分爲兩類：be + that型從句和be + 疑問詞型從句。

1. be + that型從句

eg. The fact is that we have no idea to solve this problem.事實就是我們沒辦法解決這個問題。

The reality is that the party must be cancelled because of the storm. 現實就是因爲暴風雨這個聚會必須得取消了。

2. be+疑問詞型從句

eg. The question is whether they will help us. 問題是他們會不會幫我們。

The problem is why she didn't go back home directly. 麻煩就麻煩在爲什麽她沒直接廻家。

3. 表語從句使用陳述語序。

eg. The question is when he can arrive at the hotel. 問題是他什麽時候能到酒店。

4. 主句主語是reason時，表語從句要用that引導，不可用because。但reasons作主語時，表語要用名詞短語竝列。

eg. The most common reasons for ...... are 名詞短語1，名詞短語2 and 名詞短語3。
