Answer 1

【解析】選C。考查狀語從句。句意: 你最好提前在旅館訂房間, 以防你到達時找不到房間了。in case意為“以防; 免得”, 引導目的狀語從句。

【變式訓練】

(2013·煙臺模擬)We’d better stay here a little longer　　　　he turns up unexpectedly.

A. althoughB. in caseC. sinceD. if only

選B。考查狀語從句。句意: 我們最好在這里多待一會兒, 免得他突然出現。此處in case引導一個目的狀語從句。

【知識拓展】in case作為短語連詞的用法

in case作短語連詞, 能引導狀語從句。

就其詞義和語法職能來分, 可引導兩種從句。

其一: in case/just in case引導目的狀語從句作“以免, 以備, 以防”等解。例如:

He takes a torch in case it gets dark before he returns.

他帶了手電筒, 以備天黑以后回家之用。

Please remind me of it again tomorrow in case I forget.

請你明天再提醒我一下, 免得我忘記。

其二: in case接條件狀語從句, 意為“如果, 萬一”。例如:

In case we fail, we won’t lose heart.

萬一我們失敗, 我們決不會失去信心。

Take a hat with you in case the sun is very hot.

倘若太陽很厲害, 你就把帽子戴上。

In case he arrives before I get back, please ask him to wait.

萬一我回來前他先到了, 請讓他等我。

注意: in case引出的條件狀語從句所表示的意義是“預防某種情況的出現”; 如果從句說的是一般的假設或條件, 則要用if。請比較:

I’ll tell him about the matter if I meet him. 　(不用in case)

Take an umbrella in case it rains. 　(不用if)

在上下文意義很明確時, 有時可省去in case后從句的內容。例如:

I don’t think it will rain, but I’ll take an umbrella in case(it rains).
