1.考查定语从句。分析句子结构可知，此处是非限制性定语从句关系词，先行词Tibetan Plateau在从句中充当主语，故用关系代词，又非限中不能使用that，故填which。

2.考查非谓语动词。分析句子可知，此处是独立主格，cover和逻辑主语their bodies之间是动宾关系，故用过去分词，故填covered。

3.考查不定式。句意：冬天，它们刨雪来寻找食物。结合句意和句子结构可知，此处应填表目的的非谓语动词，故填to seek。

4.考查名词的数。所给名词wolf是可数名词，根据下文的predators判断，此处用复数形式，故填wolves。

5.考查时态和语态。分析句子结构可知，此处是句子谓语动词，list和主语The Tibetan antelopes之间是动宾关系，故用被动语态；结合上下文可知，此处讲述的是一般事实，故用一般现在时的被动语态，主语是复数，故填are listed。

6.考查形容词比较级。此处应填形容词作为表语，根据than判断，此处用比较级，故填less。

7.考查冠词。此处是固定短语on the decline“在减少”，故填the。

8.考查副词。此处应填副词修饰后面的整个句子，故填Thankfully。

9.考查介词。此处是固定短语prohibit…from…“禁止……做某事”，故填from。

10.考查时态。分析句子可知，此处是宾语从句的谓语动词，根据now判断，为一般现在时，主语是复数，故填are。
