　参考答案&解析：

　　1、A　hair 可用作可数或不可数名词，用作可数名词时，指一根一根的毛发或头发，如说 There's a hair in my soup (我的汤里有根头发)；用作不可数名词时，则是整体地指一个人的头发。

　　2、B　需根据句意来分析。have no sense of direction 意为“没有方向感”。

　　3、C　price价格，价钱；prize奖金。D项是钱，属不可数名词，题中所要填的是“酬金，报酬”。注意正确理解名词的含义及其搭配是活用语言的基础，在复习备考中要熟练掌握考纲中一些名词的词义、搭配、习惯等，才能更好辨析名词，从而选择　符合句意的选项。

　　4、B　选B，由于上文说 didn't have to work，所以下文相应的语境应是 did it by choice。

　　5、B　注意其后的 to the party 和 replied to it。
