整十基数词20至90是在基数词后面加ty构成,其中 twenty,thirty,forty,fifty,eighty属不规则变化。
4. 21-99的两位数,十位与个位之间用连字符“-”,如:
73 seventy-three
88 eighty-eight
5. 三位以上的基数词,在百位和十位之间用连词and。如:
601—six hundred and one
1,342 one thousand, three hundred and forty-two
注意
6. 英语中没有“万”和“亿”,要按十进位法来推算。
10,000 : ten thousand
100,000,000 : a hundred million
35,845 : thirty-five thousand,eight hundred and forty-five
注意

1/4→ quarter
一刻钟→a quarter of an hour 或 quarter

时刻表达方式
1)整点: 数字+o’clock(o’clock可以省掉)

逆读法:先读分钟再读小时
1)分钟<30,分钟+past+小时
2)分钟=30,分钟+past+小时

4)第1、2、3特殊记忆,first=1st,second=2nd,third=3rd
eighth=8th,ninth-9th,twelfth-12th,
口诀:
基变序,有规律,词尾要加th
一二三,特殊记,词尾分别tdd (first second third )
八去t , 九去e, ve要用f替
ty变作tie,然后再加th
遇到几十几,只变个位就可以
1)表顺序,作定语,前面加定冠词。
the first bus
2)表编号,名词(首字母要大写) + 基数词 = the +序数词 +名词
Lesson One = the first lesson
用法
3)分数和百分数的表达
①分子用基数词,分母用序数词。分子大于1时,分母用复数。
基数词和序数词之间可加“-”,也可不加;分母若是2和4,也可用half、quarter。
1/2:one(-)second或one half 
3/4: three(-)fourths或three quarters
②百分数的构成:基数词+percent
80%: eighty percent
“子基母序,子>1母加s
③“分数/百分数+of+名词”作主语时,谓语动词的单复数应由名词的单复数来决定。如果是单数或不可数名词,谓语动词用单数形式;如果是复数名词,谓语动词用复数形式。
One third of the water is dirty.
Sixty percent of the workers in our factory are young people.
