Mary: What are you going to do this summer vocation?
Liming: I plan to visit Tibet for a week.
Mary: Tibet ? That sounds great. I'm dreaming of visiting there.
Liming: We can visit Tibet together. Would you like to join with me?
Mary: Really? I would love to. When?
Liming: Next week. We will walk a lot. Please wear sports shoes.
Mary: I've heard that the temperature there is lower than Shenzhen. Shall I bring some thick clothing?
Liming: Yes, The temperature there is almost 10 degrees lower than Shenzhen. You'd better bring some coats and sweaters. And the ultraviolet radiation there is strong, so remember taking sunglasses with you.
Mary: Thank you. I will do as you said.
