如果你玩儿微博，肯定不少看到各种“家用小妙招”之类的视频，或者题目为“一根皮筋儿的妙用”这类的短片，看完了不要随手关掉，想想怎么用英文讲给雅思考官啊，因为这就是a wise solution的答案啊！如果你感觉太多专业术语或者不熟悉的词汇无法完整描述整个过程，那不妨直接找到一个国外短片，然后改述一下里面的内容就OK啦！
　　比如前几天微博上很火的janitor大叔与女学生斗智斗勇的视频，就特别适合这个雅思题目：女学生总是习惯在洗手间的玻璃上留下唇印，大叔每天要花好久把它们清理掉，报告校长也无法解决，最后大叔忍无可忍，放了大招：
　　This topic reminds me of a video I watched online the other day. It was about a clever janitor in a school. The girls in that school love to leave lip prints on the mirror in the bathroom, so each and every day he had to stay late to wipe them off. So he visited the principal and asked for help. She posted a public announcement, but instead of helping, the announcement only drew more attention to this problem, and the number of prints doubled. So the janitor came up with a plan. He had the principal gather several suspects and bring them into the bathroom. There he told the students that they've been making things so difficult for him 'cause every day he had to spend so much time cleaning up those marks that are greasy and hard to get off. And he showed them what he had to do every day to make the mirror spotless again.
　　He put on a pair of rubber gloves, and dipped a cloth into the water in a toilet, and then, started to wipe the mirrors with that damp cloth.
　　The girls were so shocked and disgusted to see this. I mean, they pressed their lips to the mirror every day, and just the thought that they were actually kissing the toilet made them wanna puke.
　　So you see, I'm sure those girls would never do that again. And his brilliant idea has helped him get the last laugh.
