I hope I won't oversleep tomorrow. I have to catch the first flight to Sydney at six o’clock in the morning. Why not register a wake-up call at the reception center? If I buy a pet, will you take care of him while I'm away from the house? Sure I will, if you take care of mine while I'm on vacation. Why did you come to the class late? I left a message with your sister about the time change. You left the message with her? She has a really short memory. I have decided to take another term of American History. No kidding! In this case you can give me many suggestions on this course. I will start the introductory course next week.


希望我明天不会睡过头，我必须赶上明天早上六点去悉尼的飞机。 你为什么不在接待中心注册一个叫起床的电话呢？ 如果我买了一只宠物，在我不在家的时候你会照顾它吗？ 当然会，如果你会在我度假的照顾我的的话。 这节课你为什么迟到了？我给你的妹妹留了关于改了时间的口信啊。 你把这个信息告诉了她？她的记忆时间相当短。 我打算学另外一门美国历史。 别开玩笑了!这种情况下你可以给我很多关于这门课程的建议。我下星期就要开始这门课程的入门学习了。
