温馨提示:同学们,仔细阅读两篇文章之后,你会发现相同标号的内容采用了不同的表达方式来表达相同或相近的含义。因此,大家在平时的写作中,应该多使用一些复杂结构或高级词汇,同时,也应学会使用简单词汇或句式来表达复杂的意思。
【实战演练】
某英语报社向中学生征文,主题是“Our future life”。请你用英语写一篇短文,通过合理想象,畅想你心中的未来生活。
注意:词数100左右(题目已给出,但不计入总词数)。
Our future life
答案
One possible version:
Our future life
I always dream about life in the future. What will it be like?
Perhaps some people will go to the moon for a holiday, and some people may live under the sea or in space. Besides, probably there’ll be more educational programs on the Internet, and therefore, students will be able to study at home instead of going to school every day. What’s more, maybe in the future each family will have a robot, which will be able to do whatever it is told to, such as going shopping, doing housework, etc.
With the breakthrough of technology, I believe that our life will certainly become easier, happier and more colourful.
