理解规则
be 可以说明身份、状态或位置。现在时中,I 用 am,he、she、it 和单数人名用 is,you、we、they 用 are。中文可以说“她很忙”“我们在家”,英语中相应的完整句通常仍需要 be,不能因为中文没有“是”就省略。you 无论指一个人还是多个人,都用 are。
I + am;he / she / it + is;you / we / they + are
| 人称代词 | be 的形式 | 示例 |
|---|---|---|
| I | am | I am Anna. |
| you | are | You are late. |
| he | is | He is here. |
| she | is | She is ready. |
| it | is | It is new. |
| we | are | We are at home. |
| they | are | They are my friends. |
在例句中理解
I am Anna.
我是安娜。
主语是 I,姓名前用 am。
We are at home.
我们在家。
主语是 We,地点 at home 前用 are。
