2 在含有条件状语从句的主从复合句中主句一般不用be going to而常用will第一人称用shall。如

3 be about to do:

1 表示即将发生的动作在时间上指最近的将来。如 We are about to start. 我们就要出发了。

The new school year is about to begin. 新学年开学在即。

2 在含有be about to do的句子中不能再加时间状语。如 Wrong: The medical team is about to start immediately. Right: The medical team is about to start. 医疗队就要出发了。

附：be to do 用法的详细讲解

一般说来“be to do” 这个结构有两种语法意义

其一是连系动词，be动词不定式做表语；其二是be to是一个独立词汇单位，具有情态含义，可以把它叫做情态习语(modal idiom)。 be 动词不定式不定式做表语表示主语和表语在概念上是等同的。如

The problem is to find a solution. His plan is to clean the room. My wish is to be a doctor.

be to 动词不定式中的be to用作情态习语这时的be to do表示: “计划”、“安排”、“义务”、“应该”、“可能”、“命运”等。have to ought to。如:

He is to have a holiday. 表示将来

The committee is to meet today. 表示计划、安排

You are to go to the hotel where rooms have already been booked for you.

表示 “将”、“计划”、“安排”。意思接近于be going to 如 Their daughter is to get married soon. Who is to question him?

was/ were to do 表示过去曾经计划要做的事或者过去应当做的事而且从现在的角度来看已经实现了。如
