如下图所示，为什么第一个问题中have to buy 前面不用will， next year 表将来时间了，为什么不用will？
英语时态问题
I studying English now
进行时用be +doing 改：+am
I studied English just now
R
I am studying English now
R
I have studied English just now
过去时间不用完成时 改：-HAVE
I had studied English last year
时态不对 改：HAVE
I well study English tomorrow
R
I well studying English next year
WILL后加动词原形
I study English every day
R
英语作文《春节前准备》(将来时间
We are preparing for the Spring Festival. We will buy new clothes for the new year. We will prepare lots of food for the festival and for Spring Festival parties. On the new year's eve, we will watch the spring festival gala after family reunion dinner. It is an important day. We need to get ready for the dinner and cook great meals.
表将来的用法有？？除了现在进行时，一般将来时等等。。。还有啥？高手进
就四种：
will do 标准的将来时
be going to do 强调事物发展的必然性
be (about) to do 表示比较近的将来
be doing 有些时候可以用现在进行时来表示短暂的将来
你在吗？想问一个英语，by next year什么意思了？第2年还是将来 ？
对不起：刚上来，才看到问题 ==
by next year， 是“到下一年（明年）”，这种状语的出现，一般出现在将来完成时的句子里，
比如：
I will have studied in the middle school for three years by next year.
到明年，我就在中学学习3年了。
希望能帮到你。
