考点1 基数词
基数词主要表示具体的数量、时间、年龄等。
基数词的用法
1.表示数量的多少
There are twenty-six girls in our class. 我们班有26个女孩。
2.表示年份和年代
表示"在某年"或"在某年代"时，通常在时间前加介词in。 "in+the+逢10的表示年份的数词+-s"表示"在……世纪……年代"。如：
in the 1990s 在20世纪90年代
3.表示时刻
（1）直接表达法（即直接读出来）：小时在前，分钟在后。如：
7:25 seven twenty-five。
（2）间接表达法：在半小时（含半小时）之内，用"分钟数+past+钟点数"，表示"几点过几分";超过半个小时，用"所差分钟数+to+下一钟点数"，表示"差几分到几点"。如：
①3:15 a quarter past three
②5:40 twenty to six
【注意】"几点整"一般用"钟点数+o'clock"表示。
4.表示年龄
①a ten-year-old boy一个十岁的男孩
②at the age of four在四岁时
③when he was four years old当他四岁时
5.表示编号
由"名词单数+基数词"构成，此时名词和基数词的第一个字母通常都大写。如：Lesson Ten第十课
6.表示确定的数目和不定数目
（1）表示确定的数目："具体数字+数词+名词复数"
hundred，thousand，million等词前有one, two, three等具体数字时，这些词的词尾不加-s,表示确定的数目，其后的名词要用复数形式。如：
six hundred workers 600名工人
（2）表示不定数目："数词+-s+of+名词复数"
hundred，thousand，million等词前无具体数字时，其后加-s,并与of连用，表示不定数目。如：
hundreds of volunteers成百上千的志愿者
考点2 序数词
序数词是表示顺序的词。
序数词的表示法
1.第1—第3
one→first two→second three→third
2.第4—第19
由相应的基数词加-th构成（特殊：five→fifth eight-eighth nine→ninth twelve→twelfth）
3.第20—第90之间的整十
变化规则：基数词词尾-y变为-i，再加-eth。如：
twenty→twentieth eighty→eightieth
4.第21—第99之间的"第几十几"
变化规则：只将个位数变为序数词，十位数不变，中间用连字符连接。如：
ninety-one→ninety-first
序数词的用法
1.序数词表顺序
常用结构："the+序数词+单数名词"。
【注意】当序数词前有形容词性物主代词或名词所有格修饰时，其前不用冠词。如：
Tom is their second child. 汤姆是他们的第二个孩子。
2.序数词表"再……，又……"
常用结构："a/an+序数词+单数名词"。如：
I ask for a second chance. 我请求再给我一次机会。
考点3 分数
分数是由基数词和序数词相结合来表达的。
1.构成规则
分子用基数词，分母用序数词；如果分子大于1，分母要用序数词复数形式。如：
①三分之一 one third
②五分之二two fifths
2.主谓一致
谓语动词的数与分数后的名词保持一致。"分数+of+限定词+名词复数"作主语时，谓语动词应用复数形式；"分数+of+限定词+不可数名词/名词单数"作主语时，谓语动词应用第三人称单数形式。如：
①About two thirds of the students go to school by bus.大约三分之二的学生乘坐公共汽车去上学。
②Three fifths of the water in this area was polluted.这个地区五分之三的水被污染了。
3.quarter、half 和percent 的用法
四分之一通常用a/one quarter来表示；四分之三通常用three quarters来表示；二分之一通常用a/one half 来表示;百分之几通常用"基数词+percent"来表示，如：30%可以表达为"30 percent"。
