Unit2 A Day in the Clouds
在云间度过的一天
Language Points P16
The air is thin and we have to rest several times on the short hike from camp. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch. On the plain in front of us, we can just make out a herd of graceful animals. This is why we’re here— to observe Tibetan antelopes.

在我们面前的平原上，我们隐约看到一群体形优美的动物。
