初三英语知识点详解：Unit Three
一、知识点
1. 英语有两种语态：
① 主动语态和补动语态
主动语态表示是动作的执行者

助动词be 有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。
时态 | 被动语态结构 | 例句 |
一般现在 时 | am are +过去分词 is | English is spoken in many countries. |
一般过去 时 | was +过去分词 were + 过去分词 | This bridge was built in 1989. |
情态 动词 | can/should may +be+过去分词 must/…… | The work must be done right now |

She is a student. So am I. 她是一个学生，我也是。
She went to school just now. So did I. 她刚才去学校了，我也是。
