3、几组容易混淆的连词或词组。

We have been good friends ________we joined the same ping-pong team. [陕西省]

A. after              B. before            C. since             D. until

[答案]C。[解析] 主句是现在完成时,从句是一般过去时,填A、B、D三项其主句都不会用现在完成时。用since表示“自……以来,就……”。

None of the shoes in the shop fit me well. They are ______________too big______________ too small. [昆明市] www.zk5u.co

A. both; and            B. either; or        C. neither; nor       D. not only; but also

[答案]B。[解析] 在前句中已经给出了一个前提“商店里的鞋都不适合我”。both...and“……和……都”;either...or“或者……或者”;neither...nor"既不……也不”;not only..but also“不但……而且”。所以很容易推断出“它们(这些鞋)或者太大,或者太小。”

Please take the medicine three times a day, _______ it won’t work well.  ( 浙江)

A. and  B. but  C. or  D. so

解析:这四个单词都是连词, but表示转折;so有因此之意。and和or 都可以用于祈使句,用and,整个句子相当于if you…, you’ll…; 用or相当于if you don’t…, you’ll…。答案:C

Hurry up, Jack. We have to get to the station before 11:45 _____ we can catch the 12:00 train.          ( 南通)

A. since     B. after     C. as soon as    D. so that 

解析:本题的前三项都是表示时间的连词,因此不符合句意,so that表明“为了”、“便于”,引导目的状语从句。答案:D 

-I hear a new film is on these days. Shall we go to the cinema together, Lucy and Lily?

-_____Lily_____ I will go with you because one of us must be at home to help our father in the garden.                            ( 宁波)

A. Either, nor   B. Either, or    C. Neither,  nor    D. Both, and

解析:选项A不是一个固定搭配,C表示“既不……也不……”,选项D表示“……和……都……”,不符合句子的意思,B项则是一个选择的连词。答案:B
