关于is_am_are的区别.pptVIP

is am are is, am, are都是“是,在”的意思 但是，英语中这三个单词的用法又是不同的。下面，我们来看看一些例子，看看谁能发现这个规律。 I am a student. My father is a worker. I am a teacher. This is a cat. It is my cat. My cat is here. A cat is here. Four cats are here. 1.表示“是”的时候，如果“是，在”（is，am，are）的前面是I的时候，就用am这个“是，在”；比如 I am a student. 2.如果“是，在”（is，am，are）的前面是单数（也就是this，it, she和单数名词）的时候，就用is这个“是，在”；比如 This is my book. 3.如果“是”（is，am，are）的前面是复数的时候，就用are这个“是，在”；Three cats are here. I here. 1. is 2. am 3. are Two dogs here. 1. is 2. am 3. are My uncle a doctor. 1. is 2. am 3. are This my brother. My brother a student. 1. is, is 2. are, is 3. am, is It my cat. I playing with my cat. 1. is, is 2. are, am 3. is, am is, am, are另外的小秘密 is, am, are除了有“是，在”的意思，还能帮助句子起到一个小作用！ It is paying with a ball. I am playing with a ball. Four cats are playing with a ball. 原来它们可以帮助句子表示“正在干什么”，怎么表示呢？ is/am/are +动词ing 而且，用is/am/are中的哪一个，就跟刚刚我们做的练习题一样。 My brother climbing the tree. 1. is 2. am 3. are Four birds singing. 1. is 2. am 3. are 翻译 我正在打篮球。 I am playing basketball. 她正在唱歌。 She is singing. 我的姐姐正在弹钢琴。 My sister is playing the guitar. * 相同点 例 子 小规律 练一练 *
