一般将来时:be going to结构
1.定义:表示计划或打算要做某事。 2.be going to的用法
be going to是一种固定结构,它后面要接动词原形,用来表示按计划或安排将要发生的动作。有时也可以表示推测将要或肯定会发生的动作,有“准备,打算”的意思。在含有be going to结构的句子中往往有表示将来的时间状语。
We are going to have a class meeting this afternoon.今天下午我们打算开班会。(安排)
Look at the black clouds.It’s going to rain. 看那些乌云,快要下雨了。(推测) 3.be going to在肯定句中的形式
be going to结构中的be一般有三种形式,即:am,is,are。当主语是I时用am;当主语是第三人称单数时用is;当主语是其他人称时用are。 I am going to buy something tomorrow morning. 明天早上我打算去买些东西。
She is going to see Mr. Wang this afternoon. 她打算今天下午去看望王先生。
4.含有be going to的句子变为否定句和一般疑问句的方法 be going to的否定句和一般疑问句的构成,即在be(am,is,are)的后面加上not就构成了否定句;把be(am,is,are)放到句首,在句末加问号就构成了一般疑问句,其答语为:Yes,主语+am/is/are./No,I’m not./No,主语+isn’t/aren’t.不过I am going to...在改为一般疑问句时,常常改为Are you going to...?
They are going to visit the car factory next week.(肯定句) They are not going to visit the car factory next week.(否定句) —Are they going to visit the car factory next week? —Yes,they are./No,they aren’t.(一般疑问句及其回答)
5.标志词:常与tomorrow,tomorrow morning/afternoon/evening,the day after
tomorrow,next week/month/year,in+一段时间(如:in two weeks),soon等连用。例如: I am going to finish the work soon. 我将很快完成这项工作。
温馨提示:①there be句型的be going to结构为:There is/are going to be...,常用来表示将有某事发生。例如:
There is going to be a football match next Sunday in our school.下周日我们学校将有一场足球赛。
②come,go,leave,arrive等表示位置移动的动词常用现在进行时态表示将要发生的动作。例如:
Betty is coming tonight.贝蒂今晚要来。
