二、决定连词要把握内在逻辑
确定连词，解答连词相关的题目，与其说是语法问题，不如说是认字和理解词与词、短语与短语和句与句之间的逻辑关系问题。选择连词首先涉及连词的正确认知，其次就是搞清词、短语和句子(主句和从句)之间在逻辑上是并列、转折、因果、条件、目的等关系，从而准确地选择出连词。如：请你回答下面三个题目
例一：We’re going to Mary’s party in David’s car at five this afternoon. You can join us ___ you can meet us at the party later.
A. but B. and
C. or D. then
例二：We’re going to Mary’s party in David’s car at five this afternoon. You can join us _____ go there together.
A. but B. and
C. or D. then
例三：We’re going to Mary’s party in David’s car at five this afternoon. You can join us _____ don’t be late when you come here.
A. but B. and
C. or D. then
答案CBA。上面三个句子中，相同的语境背景是We’re going to Mary’s party in David’s car at five this afternoon. You can join us…，由于后面的三个语句不同，就形成了逻辑上的差异，因此要选择不同的连词。
又如，请你回答下面两个题目
例一：——I don’t like chicken ____ fish.
——I don’t like chicken, ____ I like fish very much.
A. and, and B. and, but
C. or, and D. or, but
例二：Along the highway, the sign board "Don't drink ____ drive." can be seen every ten kilometers.
A. or B. and
C. otherwise D. as well as
答案DB。我们知道，在并列结构中，or通常用于否定句，and用于肯定句。但在例二中，and 用在了否定句中。这是因为，这里and连接的两个事物存在内在联系，即在喝酒的前提下开车，因此，不能使用or。
再如：
例 You will succeed in the end ________you give up half way.
A.even if B.as though
C.as long as D.unless
从题干前后两个单句，我们可以看出：成功与半途而废的逻辑关系是：成功不可半途而废，而半途而废就不会成功，选项D的unless=if not，含否定意义，因此符合题干的语义。如果本句题干进行如下变换：You will not succeed in the end ________you give up half way.就应当选择if。
三、根据结构和语义进行同组连词辨析
同一个逻辑关系，如时间、原因、让步等，都有两个以上的连词可以表示，有时就不免需要辨析它们的区别，选择更加准确的用词。对此，我们可以从结构和语义两个角度来加以区别。例如：
1.since，as，for，because表示原因
例一：______it is raining, we had better take a taxi.
A. As B. For
C. Because of D. When
例二： everybody is here，let’s begin our meeting.
A.When B.For
C.Because D.Since
例三：It was he was ill that he was absent yesterday.
A.now that B.since
C.as D.because
例四He found it increasingly difficult to read, _____his eyesight was beginning to fail.
A. and B. for
C. but D. or
答案ADDB。since，as，for，because都可以表示原因，从句子的结构上说，for是并列连词，因此，for连接的句子放在后面；换句话说，for一般不放在句首。而since 和as引导的状语从句强调的是结果，而不是原因，因此它们引导的从句通常放在主句前； because强调直接原因，引导的从句根据需要，既可放在主句之前也可放在主句之后。从语义上说，since相当于“既然”；as所引出的理由很明显，不需要强调；for表示附带说明或解释。
(2) when，while，as表示时间
例一：I was about to go to bed
there was a knock at the door.
A.while B.when
C.as D.suddenly
例二： the days went on，the weather got worse.
A.With B.Since
C.While D.As
例三：——I’m going to the post office.
—— ____ you’re there, can you get me some stamps?
A. As B. While
C. Because D. If
答案BDB。用做时间状语的when，while，as ，它们的区别是：when可指时间点，又可指时间段，从句中可用延续性动词，也可用非延续性动词。while总是指一个时间段，从句中必须用延续性动词。as 表示两个动作同时发生，表示“当……时”“一面……一面”，“随着”。as 和 while表示“当……的时候”时，while 后接延续性动作，as 从句中多用表示动作的动词，而不用be动词或表示感觉等状态动词。as, when 引导短暂性动作时，当从句的动作发生于主句动作之前，只能用when 来引导，不可用as 或 while。从句表示“随时间推移”用as，不用when 或while。
