[语法精析] 并列句“四重奏”

并列句是由并列连词连接两个或两个以上的简单句而构成的句子。根据并列句之间的关系，把并列句归纳为以下四类：

联合并列句：常见的表示联合关系的并列连词有and(和)，not only…but also(不但……而且……)等。

情景例句：After lunch Aunt Huang came in and she looked worried. 午饭后黄阿姨进来了，她看起来很着急。

Not only I get up early, but also my mother does. 不仅我起床早，我妈妈也是如此。

转折并列句：表示转折的并列连词有but (但是)，yet (可是), while(而), however(然而)等。

情景例句：He is old, but he looks very young. 他老了，但他看起来很年轻。

My father wants to be a doctor while I want to be a teacher. 我弟弟想当医生，而我却想当教师。

选择并列句：表示选择的并列连词有：or(或者), either…or…(不是……就是……)等。

情景例句：You may do it yourself, or you can ask someone to help you. 你可以以自己做，你也可以请人来帮你。

Either you can stay here or you can go home. 你或者呆在这儿，或者回家。

因果并列句：表示因果关系的并列连词有so(所以), for(因为)等。

情景例句：It was too dark, so I couldn’t see anything. 天太黑了，所以我什么也看不见。

特别提示：so不能与because连用。

4. What does Mrs. Liu hate to do? 刘夫人讨厌干什么？

[词法点拨] hate表示“讨厌、不喜欢”等，后接名词、动词不定式或动名词。后接动词不定式或动名词时差别不大，一般说来，表示经常性的行为，多用动名词；表示一次性的行为，多用动词不定式。如：

She hates fish and never eats any. 她讨厌鱼，从来不吃鱼。

I hate to think about it. 我不愿想这事。

He hates studying maths. 他讨厌学习数学。
