The fresh thin air, snow-covered mountains and graceful animals running on the plains are why we’re here to observe Tibetan antelopes(羚羊), which are being hunted,     1     (illegal), for their valuable fur(毛皮).

My guide is Zhaxi,     2     (work) at the Changtang National Nature Reserve. “We’re not trying to save the animals,” he says. “Actually, we’re trying to save     3     (we).”

During the 1980s and 1990s, the population of Tibetan antelopes     4     (drop) by more than 50 percent, as hunters were shooting antelopes to make     5     (profit). To save this species from     6     (extinct), the Chinese government placed it under national protection. Zhaxi and other volunteers watched over the antelopes day and night     7     (keep) them safe from attacks. Bridges and gates were constructed to let the antelopes move easily and keep them safe from cars and trains.

    8     a result, the antelope population has recovered and in June 2015, the Tibetan antelope was removed from the     9     (endanger) species list. The government, however, does not intend to stop the protection programmes, since the     10     (threat) to the Tibetan antelope have not yet disappeared.

Only when we learn to live in harmony with nature     11     we stop being a threat to wildlife and to our planet.

Last spring，Fiona Presley，a library assistant from Scottish Highlands came across a surprising phenomenon she would never forget．While taking care of her garden，she    1    (spot)a bumblebee(大黄蜂)queen crawling around．What surprised her most was that the animal had no wings，    2    made it unable to fly．The bumblebee may have been affected by a virus in wing development．The insect had very slim    3    (chance)of survival，but this kind-hearted woman came to the rescue．

Fiona created a beautiful mini garden for the helpless animal and treated it    4    some sugar water．When it was sunny．Fiona took it out for    5    walk and protected the insect from heavy rain by taking it indoors．Soon enough the beautiful friendship unfolded between    6    (they)．Every time Fiona stopped by the garden，her tiny new friend would turn up    7    (greet)her．The bee cuddled(依偎)with the woman and seemed to light up when Fiona was holding it in her hands．

The earth bumblebees have an average lifespan of only 18 weeks，       8    Fiona was taking care of her new friend so well that it lived much longer．     9    (sad)，the friendship couldn’t last forever since the bee eventually passed away，     10     (leave)a beautiful memory to its rescuer．
