此題是考查非限制性定語從句嗎

【典型題】

If a book is in English, _________ means slow progress for you.

A. as                       B. which                   C. what                     D. that

【看分析】此題容易誤選 A或B，想當然地根據空格前的逗號認為這是非限制性定語從句。這樣分析的同學，主要是忽略了前一句句首的 if。其實此題應選D，逗號前是一個條件狀語從句，逗號后是該狀語從句的主句，that 在此代表前文所述的意思，用作主句的主語。

同樣地，下面幾題也應選 that，而不選 which：

(1) If he’s only interested in your looks, _________ just shows how shallow he is.

A. as                       B. which                   C. what                      D. that

(2) If you want to go, _________is quite all right with me.

A. that                     B. which                   C. and it                     D. so

(3) When I say two hours, _________ includes time for eating.

A. as                       B. which                   C. what                      D. that

(4) If you want a double room , _________ will cost another ￡15.

A. as                       B. which                   C.  what                     D. that

(5) If you have the money, _________ will be OK.

A. as                       B. which                   C. and it                     D. that

下例也選 that 而不選 which，其中 that 表示“那”：

Unless I’m very much mistaken, _________ is my watch you’re wearing!

A. as                       B. which                   C. what                      D. that
