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本身就相當於back或go back，此處back意義重複
2.
for改為about
worry about是固定片語，表示“為……擔心”，而worry for後加人時表示“為某人擔心”
3.
has改為had
定語從句中時態應與主句一致
4.
freshly改為fresh
fresh out of school作後置定語修飾teenager。freshly只有與過去分詞連用時才表示recently
5.
去掉who或將sitting改為sat
6.
more改為much
修飾強調比較級better
7.
classrooms改為classroom
classroom在此處是名詞作定語修飾skill，不能用複數
8.
mine後加had
過去分詞grown不能單獨作謂語，並且需要表示出在過去的過去“我的技能早已生鏽”
9.
what改為how
write後已有賓語，應用how表示方式
10.
or改為and
