Come to Austria！
Soll is a village in the mountains in western (西部的) Austria, and the Hotel Post, opened by a local family, is clean and not expensive. From the hotel you can see the whole village, the forest and the mountains. Temperatures in summer are usually 20℃ to 25℃ in the daytime, but much cooler by the evening.
Enjoy Thailand!
When you visit Bangkok in Thailand, don't miss the early morning river boat trip to the Floating (漂浮的) Market just outside the city. There you'll find many kinds of fruit and vegetables. There you can pay for them when you sit in your boat. Don't forget your hat：the sun can be strong and it may be as hot as 40℃ at noon!
Visit Hawaii (夏威夷)!
Maybe the most beautiful place in Hawaii is Kauai. You can visit its long, sandy beaches in the south and west. And there is land, mountains and forests in the north (北方), but be careful: there are many mosquitoes (蚊子). And don't be surprised (惊讶) if it rains in the middle of the island. Daytime temperatures there are usually around 24℃ to 26℃ by the sea, and only a little cooler by late evening.
