【写作技巧】用过去时态写作
就像在 【写作技巧】叙事作文的5W+1H原则 <查看文章>一文中提到的，叙事作文是一种复述过去的一段经历或一次事件的写作形式。因此，在写叙事作文时，过去时态是最为常见的时态。
什么是过去时态？
总的来说，过去时是用来谈论在过去某一特定时间发生和结束的事情的。在过去时中，动词要变形成过去形态。为了将规则动词改写成过去式形式，通常在动词后加“ed”。
- play – played
- cook – cooked
- rain – rained
- wait – waited
- Last night I played my guitar hero all night.
- 昨晚，我弹了一整夜的吉他。
- It rained yesterday.
- 昨晚下雨了。
- While we were in sleep, Angela got up early in the morning and went to see the sunrise.
- 当我们正在睡梦中时，Angela早早的起床，出去看了日出。
- Matt took the course last year.
- Matt去年上过这门课了。
- When we finally arrived in Bangkok at 4am this morning, we were exhausted.
- 凌晨4点，我们终于到达了曼谷，我们早已精疲力尽。
否定句的过去时
1.一般现在时don’t和doesn’t，过去时都变成为didn’t。 didn’t (did not)即否定句中的过去式形式。这只限于英语中的实义动词。（To be和情态动词，如can，是特例）。主动词（例如例句中的like）是用原形的。助动词Didn’t是用来表示句子是否定的，而且是过去时。
例句：
现在时：I don’t like beans.
过去式：I didn’t like beans.
2.一般现在时的Isn’t/am not/aren’t变成了wasn’t and weren’t.
例句：
现在时：I am not a teacher.
过去式：I wasn’t a teacher.
3.一般现在时的can’t,变成了couldn’t.
例句：
现在时：I can’t go.
过去式: I couldn’t go.
练习一下吧！请将下列句子改写成过去式形式：
1.We embrace challenges and rarely take no for an answer. When we find ourselves stuck, we try to keep a positive attitude. We believe there is a creative way around almost any obstacle. We don’t give up easily.
2.Boys and girls come and go like moths among the whisperings.
3.Do you understand?
