| Today is Sunday. I've been in Canada for two months . This is the first time that I've been away my family for such a long time. With the help of Katie, a roommate of me, I've soon got used to live without my parents around. Katie, like many other Russian girls, are nice and lively. We became friends shortly after we meet each other. Although her English is a little hardly to understand, we enjoy chatting and we usually talk a lot about our own family. We're both surprised that Chinese culture or Russian culture are so different. Now, we are planning a small party for the next Sunday. There, Katie will introduce me to some of her friends, one of who has been to China several times. I just can't wait. | 1. _____ 2. _____ 3. _____ 4. _____ 5. _____ 6. _____ 7. _____ 8. _____ 9. _____ 10. _____ |
