　　Ⅳ.短文改错

This morning, when I looked out of the window, I excited found it had snowed heavily. Attracting by the beautiful sight, I decided to go out to take some photo. As I walked along the path in front of our building, I saw boy suddenly slip on the snow­covered ground. It was at that moment when I realized I should do something. I run back home to get a broom and started to sweep the path. An hour late, the thick snow was being cleared away. Looking after the clean path, his neighbors all smiled and praised me.

　　1．解析：选D　细节理解题。根据第一段中的"This study joins others that show dogs are good observers of human behavior and feelings."可知，研究发现狗有时会理解人的行为及感情。

　　2．解析：选A　词义猜测题。根据第二段中的"in response to one woman, the man showed his enthusiasm and said the corns were so delicious. In response to the other woman, he gave the corns back and called them gross ..."可知，gross与delicious是反义词，所以A项Disgusting (令人厌恶的)正确。

　　3．解析：选D　推理判断题。第四段中的前两句便指明了本段的主旨大意，即关于在多大程度上狗能够理解它们身边的人类这一问题，目前还没有定论。紧接着作者讲到两次不同的实验结果并不相同，故D项正确。

　　4．解析：选D　标题归纳题。文章第一段中的"Ever get that feeling you're being watched? Well, if you're a dog­owner, you may have a point."引出文章话题，指出狗主人可能会有被注视的感觉，最后作者以"Well, either way, you can be sure Fluffs is keeping an eye on you, to the best of her ability."结束文章，所以D项作为标题最佳。
