易错点：

在否定句中，并列结构用or连接，但含有两个否定词的句子实际上被看作是肯定结构，要用and连接。

3.because“因为”，so“所以”不能同时出现在同一个句子中，只能用其一。(al)though“虽然”，but“但是”也不能同时出现在同一个句子中。

4.句型both...and的用法连接主语时谓语动词用复数形式。

句型

①连接两个成分,其谓语动词根据就近原则，与所靠近的成分保持数的一致。

②

not only…but also…可以连接两个句子，not only位于句首时，not only后的句子要倒装。

句型

either...or...,neither...nor...连接主语时，谓语动词也采用就近原则。
