Answer 1

1. A考查推理判断。根据上下文，这里是指第一批被驯化的野狗。

2. C狗是人类驯化的，这里使用了被动句，施动者应是humans。

3. B这里是由what引导的宾语从句,做介词like的宾语。

4. A当野狗饥饿时只能是偷吃人类的食物，to steal some food作目的状语。

5. D本文的中心内容讲述的就是dogs ,故A、B、C项均不符合题意。

6. C这四个选项都引导时间状语从句，但A项的意思是"当……的时候"，B项的意思是"在……以后"， D项的意思是"一……就……"，根据上下文，只有C项与题意相符。

7. B A、B、C、D四项虽都是形容词，但A、C、D项不符合题意。

8. D通过上文的介绍，我们可以得知养狗对人类很有好处。

9. B前后两句话应该是并列关系，故应选and。其他三个词均表示不同程度的转折。

10. C既然狗是我们人类忠实的朋友，那我们就应该"保护"它们，故选protect最为恰当。
