be going to do的用法
Be_going_to的用法与练习
be going to 帮你来“打算”一、概念：be going to 表示将要发生的动作或存在的状态及打算、计划或准备做某事。
属于一般将来时。
二、基本结构：①be going to + do；②will+ do.be going to的特殊疑问句形式构成方式：疑问词＋be going to的一般疑问句。
一个口诀献给大家：疑问词在句首，系动词be跟着走，主语、going紧相随，它成分不要丢。
三、否定句：在be动词（am, is, are, was, were）或情态动词will后加not成won’t。
例如：I’m going to have a picnic this afternoon.I’m not going to have a picnic this afternoon.四、一般疑问句：be或will提到句首，some改为any, and改为or，第一二人称互换。
例如：We are going to go on an outing this weekend.Are you going to go on an outing this weekend?五、同义句：be going to = willI am going to go swimming tomorrow（明天）. = I will go swimming tomorrow.但是特别注意：be going to与will两者都可表示将要发生的事、将要去做某事，但它们有如下几点区别：1. be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些，如：He is going to write a letter tonight.He will write a book one day.2. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。
He is seriously ill. He is going to die.He will be twenty years old.3. be going to 含有“计划，准备”的意思，而will 则没有这个意思，如：She is going to lend us her book.He will be here in half an hour.现在口语书面语言在互相交织的今天，从不严格的语法角度，二者互换也是可以接受的。
