● Either Mary or I am coming．
= Either I or Mary is coming．

3、not only…but also…不仅…而且…
例如：
●Not only John but also his parents like climbing mountains.
=Not only his parents but also John likes climbing mountains.
不仅John喜欢爬山，他的父母也喜欢。
4、there be 句型，表示某地“有”某人某物。
例如：
●There is a boy student and three girl students in the classroom.
=There are three girl students and a boy student in the classroom.

5、 not only…but also等连接的并列成分作主语时，其谓语通常要与靠近的主语保持一致。
