The air is thin and we have to rest several     1    (time) on the short hike from camp.    2    our left，snow-covered mountains disappear into clouds that seem almost close enough    3    (touch).On the plain in front of us, we can just make     4    a herd of graceful animals. This is     5    we’re here - to observe Tibetan antelopes.

Tibetan antelopes live on the plains of Tibet, Xinjiang, and Qinghai.     6    (watch) them move slowly across the green grass, I     7    (strike) by their beauty. I’m also reminded     8     the danger they are in. They are being hunted     9    (illegal), for their valuable fur.

My guide is Zhaxi,     10    villager from Changtang. He works at the Changtang National Nature Reserve. To Zhaxi the land is sacred and     11    (protect) the wildlife is a way of life.He says. “Actually,we’re trying to save     12    (we).”

The1980s and 1990s were bad times for the Tibetan antelope. The population dropped     13     more than 50 percent. Their habitats were becoming     14    (small) as new roads and railways were built

In order to save this species from     15    (extinct),the Chinese government placed     16    under national protection Zhaxi and other volunteers watched     17    the antelopes day and night to keep them safe     18    attacks. Bridges and gates were added     19     (let) the antelopes move easily and keep them safe from cars and trains.

The measures were     20    (effect). The antelope population has recovered and in June 2015, the Tibetan antelope     21    (remove) from the endangered species list. The government,however, does not intend to stop the protection programmes,     22     the threats to the Tibetan antelope have not yet disappeared.

I think about the antelopes and     23     Zhaxi told me. Much is being done to protect wildlife, but     24    we really want to save the planet, we must change our way of life. Only when we learn to exist in harmony with nature can we stop being     25     threat to wildlife and to our planet.
