Grammar Focus
英语有两种语态，即主动语态和被动语态。
表示主语和谓语动词之间的关系。
语态
主动语态：表示主语是动作的执行者。
Many students study English.
被动语态：表示主语是动作的承受者。
English is studied by many students.
主语
谓语
主语
谓语
宾语
宾语
被动语态的构成
被动语态由“助动词be+及物动词的过去分词”构成。其人称、数和时态的变化都是通过助动词be的不同形式表现出来的。一般现在时的被动语态的谓语形式为“am/ is/ are+及物动词的过去分词”。
This jacket is made of cotton.
Many trees are planted by us every year.
English is spoken by many people.
They aren’t allowed to go into the house.
Is the car made by a Japanese company
肯定句 主语+ am/ is/ are +过去分词（ +by… ）.
否定句 主语+ am/ is/ are +not +过去分词（ +by... ）.
一般疑问句 Am/ Is/ Are +主语+过去分词（ +by ...）？
一般现在时的被动语态的句式结构
1） 不知道谁是动作的执行者或没有必要知道谁是动作的执行者时。
The house is quite old. It was built in 1950.
这座房子太旧了，它是1950年建的。
2） 需要强调动作的对象即宾语时。
Calculator can't be used in the math exam.
计算器不能用于数学考试。
被动语态的运用:
3）有时为了礼貌等原因不愿说出行为者,这时也常用被动语态。
You are requested to give a performance.
请你给我们表演一个节目。
4）表示“据说，据报道，人们相信”等，常用“It is +过去分词+ that从句”句型。
It is believed that both of the chairs were repaired by him.
5）文章的标题、广告、新闻等用语也常使用被动语态。
Teachers Wanted. (省略了are) 招聘老师。
不能使用被动语态的情况
（1）系动词get，turn，become，seem，look，sound，smell，taste，feel等后接形容词作表语时，用主动形式表示被动含义。
eg: It smells terrible.
That shirt made of cotton feels soft.
（2）动词need，want以及短语be worth 等后接动词-ing时，
用主动形式表示被动含义。
My flowers need watering.
（3）主语是物时，sell, wash, read, write, wear等表示主语的属
性特征，常用主动形式表示被动意义。
eg: This book sells well. 这本书畅销。
The pen writes smoothly.
This kind of skirt sells well here.
（4）不及物动词或词组没有被动结构，如：take place （发生），happen（发生），come out（发生），break out（爆发）， appear（出现）， disappear（消失），last（持续）等。
（5） 表归属的动词 have; own; belong to
eg: The book belongs to Mike.
主动语态和被动语态的转化
第一步：将主动语态的宾语改为被动语态的主语；
第二步：将主动语态的谓语改为“be+及物动词的过去分词”结构；
第三步：将主动语态的主语改为介词by的宾语，放在谓语之后（有时可以省略）
主动语态：
People grow tea in Hangzhou.
被动语态：
Tea is grown (by people) in Hangzhou.
（主语）
（谓语）
（宾语）
变被动语态时要还原“to”
“一感”（feel）
“二听”（listen to, hear）
“三让”（let, make, have）
“四看”（look at, see, watch, notice）
易错点
主动语态中后接省略“to”的动词不定式
eg: The boss makes us work 12 hours every day.
→ We are made to work 12 hours every day.
They play football on Sunday.
Lucy doesn’t do the homework in the evening.
Do they often use computers in class
Where do you make these machines
