Question

You had better book rooms at the hotel in advance　　　you should find no room on your arrival.

A. so thatB. even if

C. in caseD. now that

 

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(dá)時(shí)找不到房間了。in case意為“以防; 免得”, 引導(dǎo)目的狀語從句。

【變式訓(xùn)練】

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

A. althoughB. in caseC. sinceD. if only

選B�？疾闋钫Z從句。句意: 我們最好在這里多待一會(huì)兒, 免得他突然出現(xiàn)。此處in case引導(dǎo)一個(gè)目的狀語從句。

【知識(shí)拓展】in case作為短語連詞的用法

in case作短語連詞, 能引導(dǎo)狀語從句。

就其詞義和語法職能來分, 可引導(dǎo)兩種從句。

其一: in case/just in case引導(dǎo)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(qǐng)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(huì)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(qǐng)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(yù)防某種情況的出現(xiàn)”; 如果從句說的是一般的假設(shè)或條件, 則要用if。請(qǐng)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(shí), 有時(shí)可省去in case后從句的內(nèi)容。例如:

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