1.常用并列连词的用法
1）and连接语法作用相同的部分.如： Let me know what you saw and heard in Europe. 如果连接的两个名词是指同一个人而有两种身份时,第二个名词前不要加冠词或所有格 . 如：Her husband is a singer and songwriter. 祈使句+and代替条件句. 如：Work hard and you will pass the examination. 由and连接两个主语时谓语动词要用复数形式。如：You and I are from China. 但是， and前面的主语之前有every, each, no, many a的时候用单数谓语动词.如： Every train and bus was crowded with many people. 2） both+主语+and+主语+“复数谓语动词”。如： Both Tom and Jerry are going to the cinema. 3） not only…but also如果连接两个主语,谓语动词临近原则.如： Not only he but also his parents are very kind to me. 4） as well as后面的主语不作为成分.如： This study, as well as many other reports, shows that cancer can be cured. 后面如果接动词一定要用动名词.如： She sings as well as playing the piano. 5) nor是否定连接词, 后面接的句子应倒装. 如：I don't know, nor do I care. 6）but用来表示转折,如： He tried hard but he was unsuccessful. 还可以用在no one, none, nobody, nothing, all, every等词之后表示”除了…以外”。如： All the boys but one are here.
but, however, while (而)，only (只不过)等
表因果关系 for, so，therefore (因此)，then（那么）等
