数词+冠词
(一)数词的特定表示法
小数,百分数,算数的表示方法
1. 分数表示法。(子基,母序,带and)
①. 分数的构成(分子用基数词,分母用序数词。分子如果大于1,则分母序数词用复数形式)
1/2读作:_one-second__1/3读作:_one-third____2/5读作:_two-fifths_
3/4读作:_three-fourths__1/25读作:_one--twentieth-fifths_____________
②.带分数的整数和分数之间须用and连接。
三又二分之一:_three_and_one-second__五又四分之一__five_and_one-fourth__
九又十二分之五_nine_and_five-twelfths___
注意:表示“某一整体的几分之几”时,使用“分数+of+the+名词”结构。
__One-second_of__the students are Chinese.一半的学生是中国人。
She ate __one-third_of_ her food yesterday.她昨天吃掉了食物的三分之一。
2. 小数表示法。
小数只能用基数词表示,其中小数点读作point,零读作zero(或o);小数点之后按数字依次读出;整数部分为0时可以省略不读。
0.9: zero point nine 3.58: three point fifty-eight
2.016: two point zero sixteen 8.425: eight point four hundred-twenty-five
3. 百分数表示法(% 读作 percent)
18%:_eighteen_percent__0.6%_zero_point_six_percent__0.05%_zero_point_zero_five_percent
4. 算数表达法
1+2=3 One and two is three. 12+10 =22 twelve and ten is twenty-two
3-1=2 Three minus one is two. 15-5 =10 fifteen minus five is ten
(二)冠词
冠词三兄弟a, an和the的任务就是给名词“戴帽子”。语法上,冠词是虚词,没有词义,用于名词前,帮助表明词义。冠词三兄弟的分工各有不同,大家一定要记清楚,不要“张冠李戴”。
冠词分为两类:不定冠词a/an 和定冠词the。
不定冠词a/an只能用于单数名词之前,表示“一 …”的意思或该名词的不特定性。
定冠词则强调该名词的特定性,表示“这”、“这些”等意思,在可数名词与不可数名词之前都能使用。
不定冠词的用法
A. 不定冠词的种类:
不定冠词有两个:a和an。
a用于以辅音音标开头的单词之前。
一本书_a_book_____ 一个女人__a_woman_____
an用于以元音音标开头的单词之前。
一个苹果_an_apple__ 一位老人 _an_old_ 一个小时 an_hour_ 一个鸡蛋 _an_egg__
当形容词修饰名词时,冠词要放在形容词的前面,这时用a或an取决于这个形容词的读音。
一位英语老师_a_English_teather_ 一个红苹果 _a_red_apple__
B. 不定冠词的用法:
① 用于第一次提到的、不确定的人或物(可数名词)之前
There is __a_dog outside the door 外有一条狗。
Do you see __a man_ in red T-shirt? 你有看到一个穿红体恤衫的男子吗?
② 用于价格或时间等名词的前面,是“每…”的意思

_a_ lawyer一个律师 _a_ doctor 一个医生 _a_ student一位学生
④ 用于数字、量词之前
_a_ hundred 一百 a_ lot of 许多 _a_ couple 一对
⑤ 用于一些固定词组中
