A. not wanting B. who not want C. not wanted D. are not want

2. The mountain village is my hometown. I spent ______ merry night there when I was young.

A. a great many B. plenty of C. many a D. a great deal

3. Why are you always making the same mistake? Think of _____ I told you.

A. that B. when C. how D. what

答案及解析：

1. A。not wanting 等于who do not want. 故答案為A。

2. C。many a merry night= a great many /plenty of merry nights . many a 雖然表示復數意義，但后面跟單數名詞。故答案為C。

3. D。of后面是介詞賓語從句，需要連詞且在從句中做 tell 的直接賓語；所以用 what， that 在名詞性從句中補充當成分，沒有實在意義。而B、C連接副詞，在從句中只做狀語。故答案為D。
