When I decided to return back to school at the __1__
age of thirty-five, I wasn’t at all worried for my __2__
ability to do the work. After all, I was a grown
woman who has raised a family, not a confused__3__
teenager freshly out of school. But when I __4__
started classes, I realized that those “confused
teenagers” who sitting around me were in __5__
more better shape for college than I was. They still__6__
had all their classroom skills in bright, shiny__7__
condition, while mine grown rusty from disuse. I__8__
had totally forgotten how to locate information in
a library, what to write a report, __9__
or even how to speak up in class discussion. __10__
答案及解析：
1.
去掉back
return本身就相当于back或go back，此处back意义重复
2.
for改为about
worry about是固定词组，表示“为……担心”，而worry for后加人时表示“为某人担心”
3.
has改为had
定语从句中时态应与主句一致
4.
freshly改为fresh
fresh out of school作后置定语修饰teenager。freshly只有与过去分词连用时才表示recently
5.
去掉who或将sitting改为sat
6.
more改为much
修饰强调比较级better
7.
classrooms改为classroom
classroom在此处是名词作定语修饰skill，不能用复数
8.
mine后加had
过去分词grown不能单独作谓语，并且需要表示出在过去的过去“我的技能早已生锈”
9.
what改为how
write后已有宾语，应用how表示方式
10.
or改为and
