我发现网友曹强对动词时态一直很纠结，这从他以前的提问中可以看得出来。我觉得，时态不是特别难学，关键是：不要把16 种时态混在一起学习和理解。你只需把最常用的8 种时态先掌握了，然后再适当扩展。

其实，现实语言中，11 种时态足矣，掌握了这8 种时态后，再学习现在完成进行时、将来进行时和将来完成时，也不迟。

时态问题，是动词的一个语法范畴。任何一本语法书都讲得太多太多，无须在这里重复和赘述了。因为语法书讲得太多太具体，反而无法系统理解和掌握，给学习带来障碍！我只是从个人视角阐述这个问题。

   ▲关于时态的时间范畴问题，我认为这样划分和记忆更有利于学习和掌握：

(1) 属于现在时间范畴的时态：一般现在时，现在进行时，现在完成时，一般将来时。

这4 种时态表达的概念与现在时间有关。

(2) 属于过去时间范畴的时态：一般过去时，过去进行时，过去完成时，过去将来时。

这4 种时态表达的概念与过去时间有关。

   这样划分时态的时间范畴，目的是为了时态的一致和呼应，避免时态出错！把一般将来时归到现在时间范畴，因为现在时间和将来时间在语法意义上很难完全分离。

▲请牢记这8 个句子：

1. We write a composition every week.

2. I am writing a composition now.

3. Tom has written his composition and he wants to play.

4. We will write a composition next Monday.

（现在时间范畴的时态）

5. Mary wrote a composition last night.

6. He was writing a composition when I got to his house.

7. I had written my composition before the bell rang.

8. She said she would write a composition next week.

（过去时间范畴的时态）

   ▲【8 种基本时态用于一篇短文】 好好体会就是了。

I got a letter from my sister yesterday. She lives in a foreign country. In her letter, she said that she would come to China next year. If she comes, she will get a surprise. We are living in a beautiful new house now. The building work on it had begun before my sister left. The house was completed almost a year ago. It has been the only modern house in this area ever since.

I still remember that so many of us were living in a very small house when my sister left home. But now the new house has many large rooms and there is a lovely garden. Though it looks strange to some people, it is really very comfortable.
