21.Not until I began to work ________ how much time I had wasted.

A. didn’t I realize

B. did I realize

C. I didn’t realize

D. I realized

【答案】B。【解析】考查倒装句。句意：直到我开始工作我才意识到我浪费了多少时间。not until位于句首，句子部分倒装，故排除C和D选项。而在not until位于句首时，是将not否定提前，故后面不需要再用not否定，排除A选项。故选B。

22.—She isn’t a dancing teacher, is she?

—________.

A. Yes, she isn’t

B. No, she is

C. Yes, she wasn’t

D. No, but she was

【答案】D。【解析】考查反义疑问句回答。句意：“她不是一名舞蹈老师，对吗?”“是的，(她不是一个舞蹈老师)，但是她曾经是(一个舞蹈老师)。”题干问句是反义疑问句，陈述部分是否定形式，附加问句用了肯定形式，回答时Yes译为不，No译为是的。英语中是绝对不能前后矛盾的.所以AB都错了.而C明显时态句义都不对,所以选D.反义为"不,但她曾经是." 故根据句意，选D。

A. Which

B. What

C. How

D. Whether

【答案】B。【解析】考查感叹句。句意：这种植物真奇怪!我以前从未见过。因为考感叹句首先排除A、D项。根据冠词在形容词前排除C设空处修饰的中心词是名词。故选B。

26.________ girls took part in the Happy Girl Competition but only few of them succeeded.

A. Million of

B. Many millions of

C. One million of

D. Millions of

【答案】D。【解析】考查量词。句意：“许多女孩参加‘快乐女生’的比赛,但是仅仅很少一些人成功了。”million后面跟of的时候一定要用复数形式，表示“成千上万的，许多的”，排除A，C。Many不能修饰million，排除B，故选D。
