IV.Read the letter and answer the questions (Đọc và trả lời câu hỏi) Dear Mira, Thanks for your letter. Now I’ll tell you about my hobbies. My favourite hobby is knitting. It is strange, isn’t it?. My mother taught me to knit two years ago. Now I can knit scarves and sweaters. It’s great when I can give them to my relatives and friends as gifts. Knitting is also imaginative because you can knit anything you can imagine of. Besides, it is quite cheap. You only need a pair of needles and some wool. I’m sending you a scarf next month. I’m knitting i. I hope you will like it. Best wishes, Vy 1. Who is the sender? ----------------------------------------------------------------------------------------------------------- 2.
