语法讲解：语态
英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。
例如：Alice watered the flowers yesterday.爱丽丝昨天浇了花。此句是主动语态，Alice做主语，是动作water的执行者。
The flowers were watered (by Alice) yesterday. 此句为被动语态，主语the flowers是water这一动作的承受者。
一般过去时被动语态：
一、结构
1.肯定句：主语+was / were+及物动词的过去分词+其他.
例句：The telephone was invented by Bell.
否定句：主语+ was/were not+及物动词的过去分词+其他.
例句：We are not allowed to be late for class.
一般疑问句：Was/Were +主语 +及物动词的过去分词+其他
例句：Were the T-shirts designed by the man
被动语态的用法：
1. 不知道谁是动作的执行者，或没有必要指出谁是动作的执行者。
例如：English is spoken all over the world. 全世界都在说英语。
2. 需要突出或强调动作的承受者。
例如：This dictionary is used by most students.这本字典是大多数学生在用的。
主动语态变为被动语态的注意事项：
1.含有双宾语的主动句变为被动句时，通常把指“人”的间接宾语变为主语，指“物”的直接宾语保留不变；如果把指“物”的直接宾语变为主语，则在间接语前加to或for。
例如：He sent me a photo of lucky.变为被动语态：I was sent a photo of lucky. \ A photo of lucky was sent to me.
2.主动句中感官动词see / hear / watch / feel等和使役动词make / let / have等后跟省略to的动词不定式，变为被动语态时应加上不定式符号to。
Our teacher made us stand there.改为被动语态We were made to stand there by our teacher.
3.系动词、不及物动词或某些短语动词（happen, take place, come true, fall asleep…）没有被动语态。例如：What happened to Mr. Brown 布朗先生发生了什么事？
