B. To collect manure for his crops.

　　C. To get rid of the terrible smell.

　　D. To set a good example to us.

　　答案与解析　B　考查细节理解。由第二段中的“And every week he cleaned Old Man McColgin's chicken house in exchange for manure (肥料)”可知，父亲每周打扫Old Man McColgin的鸡窝是为了收集肥料。

　　2．What can we infer about Dad's stew?

　　A. It is popular among the neighbors.

　　B. It contains honey and vegetables.

　　C. It looks very wonderful.

　　D. It tastes quite delicious.

　　答案与解析　D　考查推理判断。由最后一段中的“It would never win a prize in a cooking competition, but it was surprisingly edible, and we drank up every last drop of soup！”可知，Dad炖的菜很可口。

　　3．What does the underlined word “offend” in the last paragraph mean?

　　A. To attract.

　　B. To upset.

　　C. To air.

　　D. To shut.

　　答案与解析　B　考查词义猜测。根据画线词所在段中的信息“after the first wave had shut down my ability to smell”以及“I took a taste”可知，后来炖菜的气味也不是很难闻。所以offend意为“令人不适”，这与B选项相符。

　　4．What can we learn about Dad from the text?
