25. Try 1. －______ my computer game? －______ in the drawer. A. How’s; It’s B. Where’s; It’s C. Where’re; They’re 解析：答语中“in the drawer”意为”在抽屉里“，是一个表示在点的介词 　短语。由此可推断前面询问的是地点，应使用where进行询问。句子的 　主语computer game是单数形式，所以系动词用is, 与之相对应的代词 　是it。 答案：B 2. －Can you ______ her video cassette here? －OK. A. take B. bring C. need 解析：take意为”带走“，在方向上由近及远。bring意为“带来”，在方向 　由远及近。need 意为“需要”。here意为“这儿”，由对话的情景可以看出， 　是强调把录象带（由远处）带到这儿来。 答案：B

26. Try 3. －Where is my CD? －I ______ know. A. not B. am not C. don’t 解析：know是一个实义动词，意为”知道“，句子的主语是I ，构成否定 　时用助动词do的否定形式don’t。其实I don’t know.是口语交际中常用的 　一个短句，意为”我不知道。“。 答案：C 4. －______ you answer the questions? －Sorry, I can’t. A. Can B. Are C. Do 解析：answer是一个实义动词，在构成疑问时不能在前面加系动词，可 排除B项。can与do都可以构成疑问，但句子在意思上不一样，can是一 情态动词，意为”能“，在构成疑问时可以表示请求。do则没有这样的功 能，它只是一个助动词，没有意思。再者，句子的答语是”Sorry, I can’t”, 从这个答语上也能做出判断。 答案：A
