数 词
(一) 正误辨析
1. ［误］1107 should be read as a thousand a hundred as seven.
 ［正］1107 should be read as one thousand one hundred and seven.
 ［ 析］ 在读数字时，如and前只有百或千时，用one hundred / one thousand. 还是a hundred / a thousand全是可以的。但如果又有百又有千时，则只能用one不要用a。如果没有and时，如：1100也只能读作one thousand one hundred 或eleven hundred.
2. ［误］I drove about half mile. ［正］I drove about half a mile.
 ［析］半小时为half an hour,半天为half a day,镑为half a pound，尽量避免用half a year, half a month，要用six months，two weeks或fifteen days. 要注意的是Half of the work is done. / Half of the books are sold.当Half作名词时，其谓语动词要看of后面的名词而定。如名词是不可数名词则用单数谓语动词，如是复数名词时，则要用复数谓语动词。要注意的是一个半的表达法，如：One and a half apples is left on the table.其名词要用复数，但谓语动词则要用单数。
3. ［误］60 students are playing on the ground. ［正］Sixty students are playing on the ground.
 ［析］ 在句首的数字要用文字而不要用阿拉伯数字，如数字过大则应放于句中，用阿拉伯数字。如：There are 166 students playing on the ground.
4. ［误］He became famous around fifty years old. ［正］He became famous in his fifties.
 ［析］ in his fifties 50多岁时，而in the fifties在50年代。
5. ［误］There are about two thousands workers in our factory.
 ［正］There are about two thousand workers in our factory.
 ［析］ 几千，几百的表达法是基数词加thousand或加hundred / million，而且均不要加s。这样的单位还有dozen(打)， score (20年)等。
6. ［误］In the morning there are hundred of old people walking in the park.
 ［正］In the morning there are hundreds of old people walking in the park.
 ［析］ 当表达数百，数千时，要用hundreds of和thousands of这一结构。
7. ［误］The class begins at eight a. m. ［正］The class begins at 8 a. m.
［析］ 与符号或与缩写的字母连用时一定要用数字，如：43%，No.2…
8. ［误］Two fifth of the books are sold out. ［正］Two fifths of the books are sold out.
 ［析］ 分数表示法，分子用基数词，分母用序数词，但分子大于1时，分母要在序数词后加s。
9. ［误］Tom was born on July eighteen. ［正］Tom was born on July eighteenth.
［ 析］ 月日的表达法有美语和英语两种。美语July 18，读作July eighteenth. 英语July 18th，读作July the eighteenth.
10. ［误］ I'll go to school at 7:30 a. m. in the morning. ［正］ I'll go to school at 7:30 a. m.
 ［析］ a. m. 即表达在早上之意，不要再用in the morning.
11. ［误］The film will begin at three quarters past one. ［正］The film will begin at one quarter to two.
 ［析］ 大于30分钟时不要使用past，而要用差多少不到几点的to来表达。
12. ［误］Three time three is nine. ［正］Three times three is nine.
 ［析］ times此处作为"乘"讲一定要加s。英语中乘除法表达式如下：

语法复习十六：数 词
　　1.B
　　2. C 表示"几十"的数字的复数与所有格代词一起来用以表示人的年龄，本句为"二十多岁"。
　　3.C 定冠词"the"和数的复数形式在一起表示年代。
　　4.D 序数词前面加不定冠词表示"又一次"(已经四次了)
　　5.A 这里"first"有人说起副词作用，可以看成表语，也可以看做一种"取得第一名"的习惯用法。
　　6.D 序数词和名词共同构成的专有名词还可以是thc Second World War的形式。
　　7.C 只有C项为正确的表达方式，或者也可以写成"one or two days".再如：one hour and a half或one and a half hours.
　　8.B "in half"表示"分成一样大小的两半"。也可以说"cut…in two"
　　9.B 再如twice the height(depth，width，weight，etc.)of
　　10.D either…or…连接主语用就近原则。be to hand out the prizes意为"要颁发奖品"。
　　11.答案为B。百分比作修饰语，前面不加冠词且不能加复数。
　　12.答案为B。分数做定语，分子用基数词，分母为序数词，当分子大于1时，分母用复数，本题中，其它表达方式均不正确。
　　13.答案为A。表增加或减少的数量的百分比，用by+百分数表示。
　　14.答案为A。不可数的名词的百分比用单数;可数名词的百分比则用复数。C项时态不对，另如：90 percent of the population here are peasants.这个句子中population的意思是people.
　　15.答案为A。"dozen"与数词或many，several等词连用时复数一般不加s，故B、C两项不选。此外，dozen与数词连用做定语，一般也不加of.当然也有例外：Place them in dozens on the table.dozens表数量很多。Two dozen of these are wanted.dozen后面有of因为有限定词these，the等。Dozens of people were here.dozens of也表示"很多"。
　　16.答案为B。"半打"的表达方式一定要用"hall a dozen"。
　　17.答案为B。score做定语修饰名词用a(three)score of，而不用复数形式;常用"scores of"为其复数形式，意为"大量"，但有：three score and ten，a score or more
　　18.答案为B。"hall"起副词作用，修饰过去分词"done"，因为这个过去分词表状态，故"half"应在"done"前。再如：well done，well known，不用a half修饰done，故不选C、B两项。
　　19.B意为"同时"，不是"立刻"。
　　20.B
　　2l.A 如：tens of thousands of(小数在前，大数在后)thousands and thonsands of(两数一样大)。
　　22.B 居住的门牌号用介词at+号数+街道名"。
　　23.A
　　24.答案为D。"walk"作为名词，常与不定冠词连用。注意：在表数量的合成词中，名词部分为单数，如：a two-year-old boy.
　　25.答案为B。"在20世纪40年代"，必须有定冠词"the".此外，年代后要加's或s。"他已经40多岁了"要用in his forties。
　　26.答案为B。dozen与数词或多或少several, many连用时，复数不加s。dozens of表示数量很多，在修饰有these，the等词限定的名词时，可用dozen of的形式。如：three dozen of these eggs.
