New China reader。 第四课作业。 Translate into Chinese 1. I was afraid that these postcards that I wrote might get lost in the mail, so I asked the attendant at the window to send them by international registered post. It was expensive all right, but I felt safer. 我怕了我写的明信片可能在邮局丢了，所以我请窗口的服务员以国际挂号寄它们出去。虽然这很贵，但是我更放心。 2. There is no post office near campus. The nearest one is a little more than half an hour by foot. You had better take a bus there. 校园附近没有邮局。到最近的邮局要走半个多小时。你最好坐公共汽车去。 3. There is a store across from the bus stop for the number 22 line where you can buy envelopes and letter paper. You only have to walk outside the campus, head east, cross two streets, and then go north. You don't need to take the bus. It is only one stop away. 22路公共汽车站对面有一家商店，你在那儿可以买信封和信纸。你只要从校园到外面去，往东走，过两条街，再往北。你不要坐公共汽车去。只有一站地。 4. If you cannot get along with your roommate and want to have a single room, please go to the next counter to fill out the form. Write your name and address clearly, and in about a week we will mail you the new room number. 如果你和你的同屋谈不来也想住在单人间，请到下一个柜台填张表。把姓名和地址都写清楚，大约一周以后，我们给你发有新的房间号的电子邮件。
