冠词！是什么样的词呢？
1.a/an被称作不定冠词，用在单数可数名词前，表达某一 个人或某一事物，相当于汉语的“一”，但不强调数目概念。 e.g. It’s a pen. It’s an apple.
2.定冠词the表示该名词为特定者，表示“这”、“那”、“这些”、“那些”的意思，在可数的单复数名词或不可数名词前面都可以用。e.g. The girl in blue is my sister.

不定冠词的常见用法！
1.①相同点：a和an都通常放在单数名词前表示“一个/把/只……”。e.g. It’s a pen. It’s an apple.
②不同点：a用于以辅音音素开头的单词前；an用于以元音音素开头的单词前。 e.g. Tom is a student. I have an egg.
2. 在单词或字母前用a还是an，取决于该单词或字母的第一个读音音素，而不是该单词的第一个字母或字母本身。 如：an N，“一个字母N”。N虽然是个辅音字母，但它读作/en/，其中/e/属于元音音素，所以它前面用an。
