be going to的用法

1. be going to 结构是一般将来时的一种形式。

be going to 后接动词原形，be随主语的人称和数的变化而变化。 2. 用法

(1) 表示主语的意图，即主语计划或打算要做的事。如：

We are going to visit the zoo next week. 我们打算下周去参观动物园。 What are you going to do when you grow up? 你长大后打算干什么？ (2) 表示主语根据目前迹象所作出的推测。如：

There are so many black clouds in the sky. I think it’s going to rain soon. 天空中乌云密布，我想很快就要下雨了。 (3)与一般将来时连用的时间状语

一般将来时表示的是未发生的动作，因此常与一些表示将来时间的状语连用。如：tomorrow 明天， tomorrow morning (after noom,evening)明天上午（下午，晚上），next week (year, month …..)下周（明年，下个月…..），一周后（两天后，五年后……），soon不久，有时还与when before until等引导的时间状语从句连用。如：

They are going to visit America in a week. 一周后他们将去美国访问。

What are you going to do when you finish your work? 你完成工作后打算干什么？ (4)一般将来时的可定、否定及疑问结构。

这种时态的助动词是be，be随主语的人称和数的变化而变化。构成疑问、否定时应借助动词be。下面以动词work为例说明。 定句 定句 问句 going to work. not going to work . I going to work? You , They ) are going to work . You ,They ) are not going to work . we (you ,they ) going to work? She ,It ) is going to work She ,It ) is not going to work (she , It) going to work? 3. be going to 与be doing

两者都表示将要发生的动作，但是表示位置移动的动词，如go，come，leave，move，start，travel，arrive，fly 等，一般不用be going to 结构，而多用在现在进行时be doing表示将要发生的动作。 Hurry up! The train is leaving . 快点！火车就要开了。 4. 特别提醒

There be 结构的一般将来时应为There is /are going to be. 如：

There is going to be an English party in Class Two this evening. 二班今天晚上将有一个英语晚会。 一．用括号内动词的适当形式填空
