—Because they are very clever.
A.What
B.Why
C.When
D.Where

辨析各疑问词用法：What用于询问事物，When用于询问时间，Why用于询问原因，Who用于询问人。答语给出的是具体的节日名称，属于事物，问句要表达“你最喜欢的节日是什么”，因此用What引导。

本句为祈使句，祈使句需要以动词原形开头，句中and连接并列的谓语成分，后面的do是动词原形，因此空格处要填入动词原形，符合要求的是Keep。

() 7. —Is this CD, Bill?
—No, it isn't. It's .
A.his; her
B.hers; mine
C.your; hers
D.your; mine
—No, it isn't. It's .
A.his; her
B.hers; mine
C.your; hers
D.your; mine
答案
C
解析
本题考查物主代词的用法：1. 第一空后有名词CD，需要用形容词性物主代词修饰名词，第二空后无名词，需要用名词性物主代词。2. 先排除错误选项：A选项第二空her是形容词性物主代词，不能单独放句末作表语；B选项第一空hers是名词性物主代词，不能修饰后面的名词CD，二者均不符合语法规则。3. 结合对话逻辑：问句是向Bill询问“这是你的CD吗”，答句否定后说明物品归属为她的，语义通顺；D选项第二空mine（我的）和答句的No, it isn't逻辑矛盾，排除。最终确定正确选项为C。
() 8. —Is this Lucy's book?
—I'm not sure. It Eric's book. hers is in her schoolbag.
A.may be; May be
B.may be; Maybe
C.maybe; May be
D.maybe; Maybe
—I'm not sure. It Eric's book. hers is in her schoolbag.
A.may be; May be
B.may be; Maybe
C.maybe; May be
D.maybe; Maybe
答案
B
解析
首先区分两个结构的用法：1. may be是“情态动词may+be动词”，在句中作谓语，含义为“可能是”；2. maybe是副词，含义为“也许、大概”，一般放在句首作状语修饰整个句子。第一空所在句子缺少谓语，要填may be；第二空所在句子已有完整主谓结构，句首需要副词作状语，要填Maybe，对应正确选项为B。
() 9. I'd like two .
A.glass of water
B.glass of waters
C.glasses of water
D.glasses of waters
A.glass of water
B.glass of waters
C.glasses of water
D.glasses of waters
答案
C
解析
首先，water是不可数名词，没有复数形式，可直接排除B、D选项；其次，量词glass表示“杯子”时是可数名词，前面有数词two修饰，需要变为复数形式glasses，“两杯水”的正确表达为two glasses of water，对应选项C。
