　　单项填空 A 辨清不同功能的并列连词

　　在写作中，我们必须认真分析被连接起来的简单句之间内在的逻辑关系，然后选择恰当的并列连词，才能真正写出质量好的并列句。

　　请认真研读以下并列句，分析其逻辑关系。试试看，如果用别的功能的并列句连词替换，逻辑关系是否会仍然成立？ 例题1

　　The plane made a sudden turn and all the passengers fell sideward. 点拨

　　后一个分句的意思在前一个分句的意思的基础上有递进。 例题2

　　He failed many times, but he didn't despair.

　　点拨

　　后一个分句的意思不是前一个分句意思的顺接，而是出现转折的结果。 例题3

　　We stayed at home, for it was raining. 点拨

　　后一个分句是前一个分句的原因的补充。 例题4

　　He

　　didn't

　　work

　　hard, so he

　　failed

　　in the examination. 点拨

　　后一个分句是前一个分句的结果。 例题4

　　Hurry up, or you'll be late for class. 点拨

　　后一个分句的结果与前一个分句的结果是相反的。

　　由以上的例句可见，并列连词的选择也是要遵循句子间的逻辑关系，如果不小心，同样会犯逻辑错误。 活用

　　as if表示虚拟的时候，有三种表达形式，分别 表示对过去、现在和将来所发生的事或存在的状态 进行虚拟，而时间的判断是学习者最难以把握的。 现在我们就介绍一种简单易行的办法：以主句谓语 动词为基点，从句的动作发生在它之前，就用had

　　done；同步发生，就用did/were；发生在其后，就 用would do。 had donedid/werewould do

　　主句谓语动词　

　　之前　同步

　　之后

　　He spoke in that way as if he were a foreigner.

　　他 讲 话 的方式就好像是老外。(“讲话”与 “是个老外”同步发生) 巧记： *
