冠词和数词
一、冠词
冠词是限定词的一种，不能单独使用，常用于修饰名词。冠词有三种形式：不定冠词a / an，定冠词the和零冠词(即不使用冠词)。
1.不定冠词
不定冠词用来修饰可数名词单数，指人或物中的某一个或某一类，但不具体说明是何人何物。在名词前使用a还是an取决于该名词的发音是否以元音音素开头。如果该名词的发音是元音音素开头，应用an；如果是以辅音音素开头，应用a。
2.定冠词
the是定冠词，在以辅音音素开头的单词前读 ，在以元音音素开头的单词前读 。可数名词的单数、复数及不可数名词前均可使用定冠词。
3.冠词的用法归纳
冠词 用法 举例
不定冠词a / an （1）泛指某一类人或事物 （2）用于首次提到某人或某物 （3）用于表示数量“一” （4）表示“每一”，相当于every, one （5）用于序数词前，表示“又一” (1)A panda is very lovely.熊猫非常可爱。

二、数字
1.三位数的数字的读法
个位基数词加“hundred”,意为“几百”。如果一个数字的后面两位(十位和个位)为非零的数，则要加上and。如：

320读作：three hundred and twenty
648读作：six hundred and forty-eight
2.四位数以上的数字的读法
从数字的右端向左端数起，每三位数看作一个单位，并加一个千位分隔符“,”。从右边开始，第一个“,”前的数字后添加thousand；第二个“,”前的数字后添加million；第三个“，”前的数字后添加billion。读数时，从左往右读，每个单位里的数字按照百、十、个位往后读，遵循百位以内数字的读法。如：
2,648读作：two thousand， six hundred and forty-eight
16,250,064读作：sixteen million， two hundred and fifty thousand， sixty-four
5,237,166,234读作：five billion, two hundred and thirty-seven million, one hundred and sixty-six thousand, two hundred and thirty-four


(3)分数修饰的名词在句子中作主语时，谓语动词的单复数
由名词决定。如：

之一。
