1. 動詞跟最近主詞的句型

Neither A nor B + 動詞(跟最近的一致，動詞在後的話跟B一致)

Either A or B + 動詞(跟最近的一致，動詞在後的話跟B一致)

也就是說，此題：

Neither the teacher nor his students were(複數) in the classroom last night.

若改成teacher在後面的時候為：

Neither the students nor their teacher was(單數) in the classroom last night.

補充：

動詞在前的話跟A一致，例如題目改成疑問句的狀況會是：

Was neither the teacher nor his students in the classroom last night?

2. 動詞跟A的句型

A as well as B + 動詞(跟A一致)

A no less than B + 動詞(跟A一致)

例子：

The teacher as well as his students was in classroom last night.

3.動詞跟B的句型

Not only A but also B + 動詞(跟B一致)

例子：

Not only the teacher but also his students were in classroom last night. 

4.皆加複數動詞的句型

Both A and B + 複數動詞

例子：

Both the teacher and his students were in classroom last night.
