【语篇导读】本文以第一人称的口吻,分别介绍了北极熊和蓝鲸这两种濒危动物的生存现状。
1. to 句意:我们是陆地上最大的肉食动物,经常需要长途跋涉去寻找食物。此处用动词不定式表目的,说明长途跋涉的目的,空处应填to。
2. becoming 句意:地球正在变暖,北极的冰正在融化。is后接现在分词becoming,构成现在进行时,表示正在发生的变化。
3. it 句意:这让我们的生存变得更加困难。it作形式宾语,真正的宾语是后面的to survive,构成“make it+adj.+for sb+to do”结构。
4. hunted 句意:在过去,人类猎杀我们,我们所剩无几。根据In the past可知,句子时态为一般过去时,应用hunt的过去式hunted。
5. at 句意:现在猎杀我们是违法的,但我们仍然处于危险之中。at risk是固定短语,意为“有危险”。
