Our life is changing
Every day we can see great changes around us. Our life is becoming better and better now.
In the past, there were no subways in our city. People went to work on foot or by bike. Most families didn't have computers or smart phones. Children had few fun activities to do after school.
Now our life is very different. We can take the subway or drive cars to travel everywhere. We can talk to friends far away on the phone at any time. We can also read books, watch funny cartoons and do many other interesting things on the Internet.
I feel so happy to live such a comfortable life. I hope our life will become more wonderful in the future.

本次写作要求围绕今昔生活的变化展开，贴合六年级上册一般过去时、一般现在时的核心语法知识点，写作可按三步完成：
1. 开篇用every day等时间状语点明生活一直在发生变化，自然引出主题，语言简洁明了；
2. 先用"In the past"引出过去的生活场景，使用there be句型说明过去没有的事物，描述过去人们出行、娱乐等方面的不便；再用"Now"引出当下的生活，从出行、通讯、日常休闲多个维度和过去形成清晰对比，层次分明；
3. 最后收尾写出自己对生活变化的真实感受，贴合生活实际即可。
