一课一题一语法:新概念英语第1册第37-38课
下面是第37-38课的参考答案:
【答案】am going; are going
【简析】第一句话中有标志词now,所以go要采用现在进行时的用法;第二句话要表达的是去超市的目的,即打算买些白糖,所以要用be going to do的用法。

二、重点句型或语法
本课的语法重点还是现在进行时的用法,只是侧重的是表将来的be going to do的用法学习,其基本结构为:
主语+be going to do+其他成分
如:
We are going to leave Shanghai soon.
She is going to make a cake for her son.

本课侧重的是祈使句和be going to do的应答表达。如:
Put on your coat.
I'm going to put my coat.
本课也出现了祈使句的否定表达,即“Don't do...”。如:
Don't drop it.
Don't be afraid.

此外,要注意be going to do句型的提问与回答。如:
What are you going to do with that vase?
I'm going to put it on the table.
What are you going to do with that dress?
I'm going to send it to my sister.
