Step 3  Grammar B

1. Show sentences and join them together with the conjunctions. Give them more explanations.

both... and ..., not only... but (also) ..., either... or... 和neither... nor...都是常见的并列连词，可以连接两个并列的主语、谓语、宾语、表语、状语等。We use these conjunctions to connect the same part of two sentences to avoid repetition.

（1）both... and... 意为“……和……都；既……又……”，当both...and...连接两个主语时，谓语动词用复数形式。

I did all this both for you and for myself.

我做的这一切既是为了你也是为了我自己。

Both Li Ping and Wu Fang are league members. 李萍和吴芳都是团员。

（2）not only... but (also) ...意为“不但……而且……”, also可省略。当not only... but (also) ...连接两个名词作主语时，其谓语动词遵循“就近原则”。

Not only the students but (also) Mr Li has lunch at school.不仅学生而且李老师都在学校吃午饭。

We not only understand the text but also learn it by heart.我们不但要理解这篇课文而且要熟记于心。

（3）either... or... 意为“要么……要么……；或者……或者……”，用于连接两个表示选择关系的内容。当either... or...连接并列主语时，其谓语动词遵循“就近原则”。

You may either stay here or leave here.你要么待在这里要么离开。

Either you or I am going there tomorrow.或者是你，或者是我明天要去那里。

（4）neither... nor... 意为“既不……也不……”，具有否定含义。neither... nor...连接两个主语时，谓语动词遵循“就近原则”。
