B. READING

Read the article about Angel Falls. Then answer the questions.

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 it. I hope you’ll like it.

Best wishes,

Vy
