28.D 此处的soon after意思为“不久”，也就是在他们退休不久后，所以此处要用soon。 29.C 从前面的retire可知他们退休了，而他们退休前要做的那些事情也正如他们“刚离开的工作一样”，所以此处要用left。
30.B 根据13题后面的new toys的暗示可知退休的老人正如那些孩子一样去寻找他们新的“玩具了”，也就是说他们的兴趣也没有持续很长时间。 III. 阅读理解

IV. 微写作 书面表达范文
From the passage we know when Sally found there were so many problems among her new students, she didn't lose heart. She made some rules full of love and respect to “manage” her students. In return, her students took on a completely new look.
When it comes to my class, I have to say that I can't stand some classmates'whisper to others when the teachers are presenting knowledge. Maybe they are showing interest in what is explained, but most of time, they are talking about something having noting to do with the contents of the class.
They may disturb the teacher's thought. Worst of all, they show no respect to our teachers. Given the phenomenon, I propose to make a rule which says We Are Friends. We all hope to have more friends. But it's hard for us to make true friends.
I believe when we remember the rule, we remind ourselves that being the best listener is the first step to have friends. Our teachers are our friends. I believe all the classmates will not interrupt the teachers when they remember the rule.
