考查数词辨析.one一，基数词;five五，基数词;first第一，序数词;fifth第五,序数词.根据“Yes,hewasthewinnerof

therace.”可知，应是第一个跑过终点的，表示顺序用序数词.故选C.

2.A

考查分数的表达.three三，基数词;five五，基数词;third第三，序数词；fifth第五，序数词;threefifths五分之三;在英

语中，分数的分子用基数词,分母用序数词，当分子大于1时分母要用序数词的复数形式.故选A.

3.D

【详解】试题分析:句意:据说世界上的三分之二的水被污染了.在英语中分子用基数词表达，分母用序数词表

达如果分子大于1,分母变复数.三分之二,tw。thirds.分数，作主语时，根据其后接的词而定,如果为不可数名词,

则相当于单数，如果其后接的为可数名词复数形式,则相当于复数，根据句意及结构，故选D

考点:考查分数的用法.

4.C

【详解】句意:我希望我的父母今年能再带我去享受一次美妙的滑雪假期.

考查不定代词辨析.other其他的;theother两者中的另一个;another三者及以上的另一个;others其他人.分析句

5.B

【详解】句意:汤姆在有60名学生的班级里做了一项关于买东西的方法的调查.在商店买东西的学生比在电

子产品上买东西的学生少42人.

考查数字运算.根据“60students”可知，是对60个学生进行的调查,再结合40%+10%+10%=60%,使用手机购物

的占40%;在商店里买东西的占10%,10%x60=6,即在商店里买东西的有6人;再结合“ontheelectronicproducts”

可知，在电子产品上买东西指在电脑和手机上买东西,(40%+40%)x60=48,因此在电子产品上买东西的有48人;

再结合题干，此处比较的是在商店买东西的学生比在电子产品上买东西的学生少多少人，因此是48-6=42.故选

B.

6.A

【详解】句意:-国际劳动节是什么时候?-它是在五月的第一天.

汁的学生有200人.

考查数字运算.根据表格的第四栏可知,200名学生喜欢喝苏打水，且比例为1-25%-20%-35%=20%,所以学生总

数是200^20%=1000人，喜欢喝梨汁的学生人数为1000x20%=200.故选A.

8.B

【详解】句意:一名84岁男子在旧金山行走时遭到袭击.这个城市超过三分之一的人口是亚洲人.

考查冠词和分数的表达.a不定冠词,修饰辅音音素开头的单词;an不定冠词,修饰元音音素开头的单词;第一空

修饰man,表示“一位84岁的男子”,84(eighty-four)是元音音素开头的单词，应用an,排除A/C选项;分数的表达

结构是“先分子后分母，分子用基数词,分母用序数词，分子大于1,分母用复数"，排除D选项，故选B.

9.C

【详解】句意:爱好就像彩虹.他们可以使我们的生活丰富多彩.九年级二班有40名学生.每个人都有爱好.根据

8,playingbasketball的人数是40-10-8-5-7=10,则doingsports的人数=jogging的人数+playingbasketball的人

数=5+10=15.故选C.

词of连用，构成短语:thousandsof,成千上万的.故选A.

13.B
