　　并列复合句的连接方式：

　　1、构成并列复合句的连接方式一般有：破折号（—），冒号（：），分号（；）或并列连词and, or, but等。

　　Heis versatile — he can speak three kinds of languages.

　　Ihave finally made my goal: I want to be a scientist.

　　Sheis nice；she always helps others.

　　Ifinish my homework and I help my mother to do some housework.

　　这些符号一般起到解释说明或并列的作用，我们可以根据这些符号相互推理读不懂的部分，往往在理解上可以达到事半功倍的效果。

　　2、and, or和but衍生的其它连接词

　　从它们几个词衍生出来的并列连接词有both…and…, either…or…, neither…nor…, not…but…, not only…but also…等，这些连接词既可以连接对等的单词或短语，也可以连接句子。

　　BothPeter and Mary work hard.（单词）

　　Heis not kind but cruel. （单词）

　　Shewill either stay or leave. （单词）

　　He went to USA not only to learn Englishbut also to experience American culture. （短语）

　　He succeeded both due to his intelligenceand due to his hard work. （短语） Notonly can she sing, but she can also dance. （句子）

　　He succeeded both because he was smart andbecause he worked hard. （句子） 课堂练习1：

　　Apprentices were considered part of thefamily, and masters were responsible not only for teaching their apprentices atrade but also for providing them some education and for supervising theirmoral behavior.

　　注意一： 连接主语时，both…and…之后始终接复数动词；either…or…, neither…nor…, not…but…, not only…but also…等连接主语时，动词则要随最近的主语做单复数变化。

　　Bothhe and I are happy about it.（看两个主语，动词

　　复数）

　　Eitherhe or I am wrong. （看后面的主语，动词单数）

　　Neitheryou nor he is right. （看后面的主语，动词单数）

　　Not he but I am to be responsible for it. （看后面的主语，动词单数）

　　Not only they but also John has passed theexam. （看后面的主语，动词单数） 注意二：not only由于是否定副词的关系，若置于第一个分句之前，则该句要采用倒装结构。而but also为连接词，所以连接的第二个分句不需要倒装。一般在改写的时候，情态动词或be动词直接提前即可，而行为动词则需要另加do、does或did等助动词于主语前，原有的动词一律改成动词原形。

　　Notonly she can sing, but she can (also) dance. 改为

　　Notonly can she sing, but she can (also) dance.

　　Notonly he is clever, but he is (also) polite.改为

　　Notonly is he clever, but he is (also) polite.

　　Notonly she sings well, but she (also) dances excellently.改为

　　Notonly does she sing well, but she (also) dances excellently.

　　3、as well as 与ratherthan作并列连接词

　　与and,or类似，这两个词也是并列词，也可以跟单词、短语和句子。

　　We as well as John like it.（连接两个单词）

　　He is joyful rather than upset. （连接两个单词）
