be going to出生在"一般将来时"家族里,表示将来某个时间将要发生的动作或存在的状态。

　　"be going to"由三个词组成。这三个词分开来都有自己的意思。但组合在一起，只表示"打算，将要"。其中"be"妈妈会根据主语的人称变化派出孩子们"is,am,are"来完成任务。"to"是"不定式符号"。它有一个脾气，跟在它后面的动词必须是动词原形.

首先，我向你们展示我的几种句型。　　

一、陈述句(肯定句)

在肯定句中，小精灵的模样是：主语+be(am / is / are) + going to +动词原形+其它。如：

1、I am going to work hard this term.我打算这学期努力学习。

2、He is going to buy a new CD after school.我放学后要去买张新CD。

3、They are going to visit their teacher tommrow.他们明天要去看望他们的老师。

在否定句要在be的后面加not.不信你来瞧：

1、I am not going to play football after school.我不打算踢足球。

2、She is not going to watch TV this afternool.今天下午她不打算看电视。

3、We are not going to the cinema at night.我们今晚不看电影。

二、一般疑问句

这时候，小精灵模样是：Be(am is are)+主语+going to+动词原形+其它,如：

1、 Are you going to read books tonight? -Yes, I am. -No, I am not.

2、Is he going to buy a comic book this morning?-Yes, he is.-No, he is not.

三、特殊疑问句

疑问词+be(am is are)+主语+ going to+动词原形+其它,如：

1、What is she going to do this evening?

She is going to visit her grandparents.

2、What are they going to do tomorrow?

They are going to play football.

其次，和他出现的朋友还有以下特征：this morning, this afternoon, this evening, at night, tomorrow, this weekend, next week，soon等表示将来时间的词语。  

还有，我有时会偷懒的，如表示你将要去哪儿的句子时：

I am going to the park this morning.

Where are you going this weekend?
