【语法——连词】，学习英语的话英语可是很重要的哦，大家赶紧来5068频道看看浅陌带给大家的语法总结吧。

　　好了，现在我们在攻克词类的最后一个堡垒——连词。连词更好对付了，我们只讲几个常考的词组就可以了。

　　连词常考到的有以下几个词组：

　　both ...and：表示"两者都...".注意：当both...and 连接主语时，后面动词一般要用复数。如：Both

　　Lily and Lucy are right.

　　not only... but also: "不仅...而且..."。注意：后面动词采用就近原则,与but also后的词保持一致。

　　如：Not only my parents but also my brother likes the cat.

　　either...or:"或者...或者..."。注意谓语动词采用就近原则。如：Either you or I am wrong.

　　neither...nor："既不...也不..." 是 "either...or" 的否定形式。谓语动词采用就近原则，与nor后的

　　词保持一致。　　如：Neither you nor he is right.

　　or的用法： 意思为"否则"。如：I must work hard, or I'll fail in the exam.(我必须好好学习，否则

　　我会考不及格了。)
