We went to Xizang to observe Tibetan antelopes with Zhaxi as our guide. Luckily, on the plain in front of us, we saw a herd of antelopes 1.moving (move) slowly across the green grass. These beautiful animals reminded me 2.of the danger they were in because every year many of them were hunted 3.illegally (legal) for their valuable fur. Especially in the 1980s and 1990s, their population dropped 4.by more than 50 percent. In order 5.to save (save) this species from extinction, the Chinese government placed it 6.under national protection and set up the Changtang National Nature Reserve where Zhaxi works. These measures were 7.effective (effect) and the antelope population has recovered. However, the government doesn't intend 8.to stop (stop) the protection programmes, since the threats to the Tibetan antelopes have not disappeared. Only when we learn to exist in 9.harmony (harmonious) with nature can we stop being 10.a threat to wildlife and to our planet.

答案： 1.moving 2.of 3.illegally 4.by 5.to save 6.under 7.effective 8.to stop 9.harmony 10.a

Ⅱ. 分析长难句
1. To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch.
[句式分析] 此句是复合句，其中 to our left 为状语；that 引导定语从句，修饰 clouds，在从句中作主语。
[自主翻译] 在我们的左边，白雪皑皑的群山消失在似乎触手可及的云层中。
2. The government, however, does not intend to stop the protection programmes, since the threats to the Tibetan antelope have not yet disappeared.
[句式分析] 此句是复合句，intend to do sth. 意为“计划/打算做某事”，the threats to 意为“对……的威胁”；since 引导原因状语从句。
[自主翻译] 然而，政府并没有打算停止这些保护项目，因为对藏羚羊的威胁依然存在。
3. Much is being done to protect wildlife, but if we really want to save the planet, we must change our way of life.
[句式分析] 此句是并列复合句，is being done 是现在进行时的被动语态，but 为并列连词，表示转折，if 引导条件状语从句。
[自主翻译] 大量的工作正在进行中以保护野生动物，但是，如果我们真的想拯救地球，就必须改变我们的生活方式。
4. Only when we learn to exist in harmony with nature can we stop being a threat to wildlife and to our planet.
[句式分析] 此句是复合句，“Only + 状语从句”置于句首时，主句用部分倒装，即把情态动词放在主语之前；短语 exist in harmony with 意为“与……和谐共处”。
[自主翻译] 只有学会和大自然和谐共处，我们才不会成为野生生物和地球的威胁。
