四月一号愚人节。李华到处去找Michael, 有事商量。今天她会学到两个常用语，sketchy和sucker。

　　L：Michael，和我住在一起的小陈今天打电话到我工作的地方。她说警察到家里去找我。他们说我的签证有问题。我该怎么办？我很害怕。

　　M：What? I don't believe her. That story sounds sketchy.

　　L：你说听起来什么？你不信小陈说的话？

　　M：That's right. I said her story is "sketchy" . That means it is suspicious and cannot be trusted.

　　L：噢，sketchy就是可疑，不可信。你怎么知道小陈说的话不可信？

　　M： Well, for one thing, the police usually don't care about visas. They are too busy looking for serious criminals.

　　L：嗯，对呀，警察抓罪犯还忙不过来呢，他们才不管签证呢！移民局的人才是管签证的。这么说来，小陈的话是有点可疑，sketchy。

　　M：Also, I don't think the police or immigration officers would go to your house. That sounds very sketchy.

　　L： 对，Michael， 你可真行呐！ 要是签证有问题，移民局一般会先给我一封信，他们才不会到家去找我呢。这真是越说越不可信了。

　　M：But if you want to know what's really sketchy, you should remember what day it is.

　　L：今天是什么日子呀？噢。。。今天是四月一号愚人节！ 哟，我的老天爷呀，我没想到小陈会跟我开这个玩笑。

　　M：Heh heh, your roommate is pretty sketchy too, if you ask me.

　　L：等等，你也能说一个人sketchy? 你觉得小陈这个人不太可信？对，她的话确实是靠不住。上星期在聚会上见到的那个人，死跟着我不放，楞要送我回家，我能不能说，that guy was very sketchy?
