module 3 语法要点be going to用法1. 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。含有be going to 结构的句子中往往有表示将来的时间状语。例如：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. its going to rain.看那些乌云，快要下雨了。（推测）2. be going to 在肯定句中的形式be going to 结构中的助动词be很少用原形，它一般有三种形式，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。例如：i am going to buy something tomorrow morning.明天早上我要去买些东西。she is going to see mr. wang this afternoon.她打算今天下午去看望王先生。3. 含be going to 的句子变否定句和一般疑问句的变法由于句子中有助动词be，因此be going to 的否定句和一般疑问句的构成很容易，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, 主语+ isnt/arent. / no, im not.不过 i am. 在改为一般疑问句时常常改为“are you .?”。例如：they are going to see the car factory next week. (肯定句)they are not going to see the car factory next week. (否定句)-are they going to see the car factory next week?-yes, they are. (no, they arent.) (一般疑问句及其回答)4. 使用be going to 应注意的两点（1）there be 句型的be going to 结构为：there is / are going to be. (注意句型中going to 后面的be不能改为have。) 常用来表示将有某事发生。例如：there is going to be a football match next saturday in our school.下周六我们学校将有一场足球比赛。（2）come, go, leave, arrive等表示位置移动的动词常用现在进行时表示将要发生的动作，它们很少与be going to 结构连用。例如：miss sun is coming tonight. 今晚孙小姐要来。练习一、按要求进行句式转换, 每空一词1. is brian going to water his trees this weekend?
