拓展：同位語從句the appositive clause
（1）同位語從句的定義
在復合句中用作同位語的從句稱為同位語從句。同位語從句是名詞性從句的一種。它在句中起同位語的作用。它一般放在fact, news, idea, truth , hope , problem, information, belief, thought, doubt, promise, question 等名詞的后面, 對前面的名詞作進一步的解釋, 說明前面名詞的具體含義。引導同位語從句的詞有連詞that, 連接副詞how, when, where, whether, what等。
e.g. the hope that he may recover is not gone yet.
the problem whether we should continue to do the experiment has been solved.
i have no idea when he will come back.
注意：同位語從句有時被別的詞把它和名詞隔開：
the story goes that william tell killed the king with an arrow.
word came that their team had won.
（2）同位語從句的表現(xiàn)形式:
① 由that引導
the fact that you haven’t enough time to do the work is simply unbelievable.
② 由whether引導
the question whether we need more time to do the work has not been discussed.
③ 由when引導
i have no idea when they will go.
（3）有時可用 namely （即）, that is to say （也就是說）, in other words （換句話說）, that is （那就是）, for example 等引出同位語, 說明其前面的名詞或代詞。有時同位語直接跟在名詞或代詞的后面。
he told us the good news, namely, the museum is open to all.
there is only one way of improving your english , that is , to practice more.
（4）同位語從句與定語從句的區(qū)別：
同位語從句與定語從句在使用中常常混淆，我們可以從以下幾個方面區(qū)別它們：
①同位語從句說明的名詞大都是抽象名詞；定語從句所修飾、限定的名詞或代詞有抽象的也有不抽象的
we express the hope that they will come to visit china again.（同位語從句）
those who want to go please sign their names here.（定語從句）
② 同位語從句所說明的名詞與從句沒有邏輯關系；
定語從句所限定的名詞是從句邏輯上的主語、賓語、表語、定語、狀語等。
the news that they won the match is true.（同位語從句，news和從句沒有邏輯關系）
the news that you told us yesterday is true.（定語從句，news是told的邏輯賓語）
