　　答案解析：

　　1.答案是: A

　　解析: hair 可用作可數(shù)或不可數(shù)名詞，用作可數(shù)名詞時(shí)，指一根一根的毛發(fā)或頭發(fā)，如說(shuō) There's a hair in my soup (我的湯里有根頭發(fā));用作不可數(shù)名詞時(shí)，則是整體地指一個(gè)人的頭發(fā)。

　　2.答案是: B

　　解析:需根據(jù)句意來(lái)分析。have no sense of direction 意為"沒(méi)有方向感"。

　　3. 答案是：C。

　　解析：price價(jià)格，價(jià)錢(qián);prize獎(jiǎng)金。D項(xiàng)是錢(qián)，屬不可數(shù)名詞，題中所要填的是"酬金，報(bào)酬"。注意正確理解名詞的含義及其搭配是活用語(yǔ)言的基礎(chǔ)，在復(fù)習(xí)備考中要熟練掌握考綱中一些名詞的詞義、搭配、習(xí)慣等，才能更好辨析名詞，從而選擇更符合句意的選項(xiàng)。

　　4.答案是: B

　　解析: 選B，由于上文說(shuō) didn't have to work，所以下文相應(yīng)的語(yǔ)境應(yīng)是 did it by choice。

　　5.答案是: B

　　解析: 注意其后的 to the party 和 replied to it。
