人教版八年级英语上册 unit6 语法+知识点

Unit 6 I’m going to study computer science.

否定结构：be not going to do / will not dozaq (won’t)

will 与be going to两者都表示将来要做的动作，但还是有区别的。

一、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：We are going to take a walk tonight. I will visit you in a month.

二、在表示将来发生的事情时，be going to用于主观判断，will则多用于客观的情况。

如：He is going to die. 他就要死了。She will be thirteen years old. 他就快13岁了。三、be going to含有“打算，准备”的意思，而will则没有这个意思，

如：Tomorrow I am going to wake up at 7:00. Everyone will learn English.

四、在有条件从句的主句中，主句中一般不用be going to, 而多用will.

如：If he comes, I'll tell you. 如果他来了我会告诉你。

五、可表示说话人按照他的意图将要发生或进行的动作时，各有侧重：

若事先计划或考虑，而是在说话的当时临时想到的意图或临时作出的决定时，则要用will。若表示经过事先考虑好的意图时，要用be going to。例如：

I’ll answer the telephone.（事先没经过考虑）

I’m going to meet him at the railway station. （已经过考虑）

六、在正式的通知（如新闻媒体公布的官方消息，气象预报等）中用will。例如：

Ji’an will be cloudy with the temperature from eighteen to twenty-eight.(吉安阴，气温十八到二十八摄氏度。)

七、表示有迹象表明要发生某事，只用be going to，不用will。例如：

Loo k at the clouds, it’s going to be rain.
