heavy and cold that   1   felt like big pieces of ice. Have you   2   seen snowmen ride bicylces? That"s
what we looked like! Along the way children who were   3   long wool coats stopped to look at us.
In the late   4   we found it was so cold that our water bottles froze (结冰). However, the lakes   5

To climb the mountains was hard work but as we   7   us, we were surprised by the view. We seemed

At the foot of the mountains, colourful butterflies flew around us and we saw many sheep eating green
grass. Then we had to  10 . Our caps, gloves and trousers for T-shirts and shorts.

went to sleep but I stayed  12 . At midnight the sky became clearer and  13  and the stars grew brighter.
As I  14  below the stars I thought about how far we had already travelled.
