想象类作文是作者根据自己已有的生活经验和知识，超越实际生活来勾画从未见过的或者不曾出现过的生活图景的文章。写作时应注意以下几点：
1．采用记叙文或说明文的形式，围绕主题来逐一列举所给要点。
2．要用一个明确的主题。想象类作文虽然题材广泛，但所选的材料必须紧扣这个主题。
3．要有现实依据。
4．任何文章首先要确定时态(一般将来时为主)、人称(可采用第一人称或第三人称来叙述)和写作手法，想象类作文也不例外。一般来说这类作文中描述性词句比较多。写作时多用表示将来的句型：will，will be doing，be to do等；正确运用表示推测的情态动词：may，might，could，would等；选择运用表达可能性的词汇：possible，probable，likely，may，maybe等。
1．开头常用的句式：
Sometimes I dream about life in the future.
I imagine life in the future from time to time.
I am curious about future life.
It's fascinating to imagine life in the future.
2．表达预测的常用句式：
Maybe in the future we can...
There is a possibility that human beings will...
Perhaps some people will...
We will be living...in the future.
3．结尾常用句式：
I believe the dream will come true some day.
In my opinion，the dream will be turned into reality one day.
As far as I'm concerned，we will realize the dream sooner or later.
