基数词及其用法。
一、选择填空。
1.B【解析】hundred“百”,在表达名词数量时,若前面有具体数字时用单数形式,此时不加of。故
2.B
【解析】在读取数字时,从右到左,每三位一节,用逗号分开。第一个逗号读thousand,根据eighty-five
thousand可知选B。
3.D【解析】Thousand“千”在其前面没有确切数字时,表示数以千计,此时,要后缀-s,还要加of。故选D.
4.B【解析】表示号码用基数词,且不加冠词。故选B。
5.C【解析】表示年龄用基数词,表示“……岁的”是用作形容词,无复数。故选C。
6.D【解析】表示数字的hundred,thousand和million,前面有具体数字修饰时,不加-s,与of连用表示一个概数时,要加-s。
7.D【解析】几岁应该用基数词,因为Tom只是个中学生,所以不可能是30岁,因此选D。
8.A【解析】二月通常有28天。
9.B【解析】房间号用基数词,且用Room….。故用A。
10.B【解析】本句子的两个空都是用“名词+
基数词”的方法表示编号,page
twenty意思是“第二十页”;
picture
one表示“图画一”的意思。故选D。
二、根据数字的提示,用适当的数词形式填空。
1.
forty-five
2.
seven
3.
thirty,
thirty-one,
three
hundred
and
sixty-five,
three
hundred
and
sixty-six
4.
sixty
序数的用法
一、选择填空。
1.
D【解析】本句子的第一个空是用“名词+
基数词”的方法表示编号,page
twenty意思是“第二十页”;第二个空前面出现了定冠词the,名词在数词后面,所以用序数词来表示“第一幅”的意思。
2.
B【解析】从句子的意思理解,他的前面已经有四个人,所以他是第五个。在定冠词the的后面用序数词,选项C也是序数词,但不符合句子的意思。
3.
B【解析】在定冠词the的后面用序数词表示第几的意思,同时还要了解一些文化常识即母亲节是每年五月第二个星期天,所以用序数词second。
4.
C【解析】月日的表达。日要用序数词,序数词形式正确的有B,C项;一个月最多只有31天,因此B项错误。所以正确答案是C。
5.
C【解析】四月是一年中的第四个月,4的序数词是fourth,所以选C。
6.
B【解析】句意:“这个女孩十二岁了,今天是她的第十二个生日。”由此可知,第一个空用基数词,第二个空用序数词。故选B。
7.D【解析】根据句意,问句用序数词,表示“第十五个生日”,答语用基数词,表示“大约15个朋友”。
8.
C【解析】星期天是一周的第一天,所以选C。

一、选择最佳答案
1.
D【解析】由twice(两倍)和energy后的as可知,此题是考查用“倍数+as+形容词原级+as”来表达倍数的方法。
2.
D【解析】倍数three
times要放在as的前面,后面省略as
I
paid
at
home。
3.
D【解析】倍数放在as之前。此题与全国卷曾考过的一题几乎一样:
4.
B【解析】倍数three
times要放在the
weight
of之前。若选项D中heavier改为heavy也对。
5.C【解析】倍数放在as之前。
6.B【解析】基数词用来表达事物的量;序数词用来表达事物的顺序。本题的第一空表示顺序用序数词second;第二空用基数词three,答案为B。
7.A【解析】分子在前用基数,分母在后用序数。分子大于一,分母用复数,分子与分母之间可以用连字符连起来也可以不用连字符,如two
thirds或two-thirds;当分数修饰名词作定语时,后要跟of,如:two
thirds
of
students三分之二的学生。本题的选项中只有A项正确。
8.B【解析】表示单位的数词用法分两种情况:1)当放在具体的数字后边,表示具体的“百、千、百万、十亿”时,不能用复数形式,可以直接修饰名词复数,如two
thousand
students;2)当表示大概的“几百、几千、几百万、几十亿”时,用“复数形式+of”结构,前边不能用具体的数字,如:thousands
of
students。只有B项正确。
9.A【解析】“基数词+可数名词单数”中间用连字符连接,一般用作定语修饰名词,相当于“数词+名词所有格”.
10.A【解析】at
the
age
of
后面跟具体的数字,为固定用法。

数词
命题趋势
单项选择部分很少涉及对数词的考查,但在听力部分和词语运用部分考查较多,完形填空中也偶尔涉及。听力部分主要考查数词的基本用法和读法,如数字辨音;词语运用主要考查基数词和序数词的相互转化;完形填空主要考查数词在语境中的基本用法。预测以后在听力部分和词语运用题对数词的考查会以数字辨音和词性转换为主。
考查题型:对数词的考查主要分布在单项选择和完形填空中。
考查重点:对数词的考查主要包括以下几个方面
1.基数词和序数词的构成和基本用法;
2.日期、时间、年龄、编号等的表示法;
3.分数的表达法以及分数作主语时谓语的单复数形式;
4.hundred,thousand,hundreds
of,
thousands
of
在具体语言环境中的运用。
一、基数词的词形及用法。
数词的概述
一、数词的定义:
英语中用来表示事物的数量或顺序的词叫做数词。根据数词的特征,可将数词分为基数词和序数词
(?http:?/??/?www.?/?Article?/?adv?/?Index.html?);根据数字是否为整数,有可将它分为整数、分数和小数;根据数字所表示的数是否确定,有可分为定数和概数。数词在句中可用作主语、表语、宾语、定语、同位语、状语等。
在表示基数词
(?http:?/??/?www.?/??)时,要特别注意hundred,
thousand,
million,
billion等几个词的用法:若其前用了基数词
(?http:?/??/?www.?/??),则不论其面是否有of,都必须用单数形式(此时若带of则通常表示特定范围中的一部分);若泛指数百、数千、数百万等,则用
hundreds
of,
thousands
of,
millions
of
等这样的结构。
