参考答案

1．B

【详解】

句意：——书包里有多少书是你的？——没有一个是我的。

考查不定代词辨析。No one表示没有一个人，不指物；None表示数量，没有一个人或物；Not one中not表示部分否定或全部否定；Not表示否定，不能直接和of连用。根据how many books可知，问的是书的数量，是物，表示“没有一个是我的”，故用None。故选B。

2．C

【详解】

句意：一条小河穿过我的村庄。河里面有很多鱼。A. cross动词，穿过。横穿或表面穿过；B. in介词，在…里面；C. through 介词，穿过，指“纵穿或内部穿过”；D. out副词，在外面。goes动词，此处需要介词。小河从村庄“内部”穿过。故选C。

3．D

【解析】

句意：关于我们看电视的问题的答案很有趣。of属于；about关于…；to到、针对…；do做。第一个空The answer to…"…的答案"固定搭配，第二个空，about关于…，结合句意可知，答案为D。

点睛：the answer to this question这个问题的答案，类似的表达方法还有：the key to the door，the way to the bookstore；the entrance to the cinema；the secret to language learning

4．C

【解析】

句意：简是一个16岁的美国高中生。16-year-old 复合形容词用作定语，修饰后面的名词，注意有连字符时year不用复数；故答案选C。

点睛：复合形容词的构成为：基数词+名词的单数+形容词，中间用连字符号，注意名词用单数形式。如：a five-merer-tall tree一棵5米高的树；an eight-year-old boy一个8岁的小男孩。注意复合形容词只能用作定语，不能用作表语。如：The gilr is three- year- old.就是一个错误的句子，只能说The girl is three years old.或 This is a three-year-old girl.

5．A

【解析】

句意：我们都知道，地球的75%被水覆盖。基数词+percent of表示……的百分之几十，由分数修饰的主语后面谓语动词的数，和被修饰主语的单复数保持一致。earth表示单数含义，故答案选A。

点睛：“half of, the rest of, most of, all of及百分数或分数+of 等后接名词”作主语时，谓语动词形式根据of后的名词而定，例如：

Three fourths of the surface of the earth is covered with water.地球表面四分之三为水所覆盖。

The rest of the lecture is wonderful. 讲座的其余部分精彩极了。

50% of the students in our class are girls. 我们班50%的学生是女生。

6．A

【解析】

句意：喝牛奶对你的健康有好处。考查固定短语be good for 对…有好处，首先排除C,D；为了避免头重脚轻，这里it是形式主语，后面的动词不定式是真正的主语，牛奶是不可数名词，不能用a修饰，故答案选A。

文章大意：文章主要讲述了旧习难改的道理。走下坡比上坡更容易，所以养成坏习惯比养成好习惯更容易。告诫人们在开始时摒弃坏习惯很有必要。
