We seemed to be able to see for miles, and we were so high that we found ourselves cycling through clouds. After a while, we began going down the mountains. It was great fun especially as it slowly became much   7  . At the foot of the mountains, colourful butterflies flew around us and we saw many sheep eating green grass. Then we had to change our caps, gloves and trousers for T-shirts and shorts.

In the early evening, we put up our tent and then we ate. After supper Wang Wei went to sleep   8  I stayed awake (醒着的). At midnight the sky became clearer and the stars grew brighter. As I lay below the stars I thought about   9   we had already travelled.

How would you like to live in a land where the sun shines day and night? There are place in the polar regions where, for North, the sun never sets! This is known as the land of the Midnight Sun. This period of sunlight can last up to six months.

This happens because the Earth tilts(倾斜). When the North Pole is tilted towards the sun, it has constant (不断) daylight. As the same time, the South Pole is tilted away from the sun. It is in darkness.

Six months later, the South Pole tilts to the sun and has constant daylight. Then the North Pole is tilts away. It has darkness.
