1因为他问：你们什么时候动身,是还没做的事情,所以用将来时
When will you leave?
2我们是主格,应该用we,明天是还没做的事情,所以也用将来时
We will go to Nanjing tomorrow.
3这个是部分倒装句,将时间放在后面,放在前面一定要加逗号,下课后我去找你是还没做的事,所以也用将来时
I will search for you after class.
After class,I will go to search for you.
4soon作为修饰词应该放在最后,此句子用将来时
Mother will buy me a bicycle soon
Mother will buy a bicycle for me soon.
上面的buy…to 明显错误,应该是buy…for.
