『壹』 初中英语里什么是主动语态和被动语态

『贰』 英语高手。关于初中的语法。哪个是主动。哪个是被动
要弄懂这个问题，首先要搞懂interest的意思。interest作动词，意思是“使人感到有趣的”。
第一版句“he
is
interesting”中，
“he”是施动方权，发出的动作是“让别人感到有趣”。例如，“他”，可能有幽默感，爱讲笑话，妙语连珠，因此能让别人感到妙趣横生。
而第二句“he
is
interested
in
sth”他对某物感兴趣中，“he”是受动者，施动者是“sth”，意思是“sth”非常“有趣”--interesting（形容词，有趣的）让“he”感到妙趣横生。
综上，您的理解中唯一的问题出在interest不是“被人感到有趣”，而是“使人感到有趣”。
请您把这个意思带回到问题中，这样就说的通了。
『叁』 初中英语主动语态与被动语态转换
被动语态八注意
1.我们知道,主动语态变为被动语态时,通常将主动语态中的宾语变为被动语态的主语;主动语态的主语变为由介词by引导的宾语;谓语动词变为被动语态“be +过去分词”形式,例如: Everyone likes the interesting film. (主动语态) → The interesting film is liked by everyone. (被动语态) They used knives to cut things. (主动语态) → Knives are used to cut things. (被动语态) 但是,并非所有由“be +过去分词”构成的形式就是被动语态。有时过去分词已经变为形容词,表示一种状态。试比较: My brother is very interested in English. 我哥哥对英语非常感兴趣。(状态) My brother was interested by what I told him. 我告诉他的话让我哥哥非常感兴趣。(动态) 2.在被动语态中谓语动词一定是及物动词,也就是说必须跟宾语的动词。如: We can make metals into different shapes. (主动语态) → Metals can be made into different shapes. (被动语态) 在主动语态中make是及物动词,其动作的承受者即宾语是metals。 但是,并非所有的及物动词都有被动语态。比如,表示静态的动词(have、belong to)、宾语是反身代词或相互代词等。例如: He has a nice house. 他有一所漂亮的房子。 We must help each other. 我们应该互相帮助。 3.主动语态中的主语在变为被动语态时通常变为由介词by的引出的宾语。如: They have already cut down the trees. → The trees have already been cut down by them. 那些树木已经被他们砍光。 如果谓语动词是know,在变为被动语态时,原来的主语变为由to引出的宾语。如: May people know him very well. → He is well known to many people. 很多人都非常了解他。 注意:我们之所以用被动语态是因为我们不清楚动作的执行者、或没有必要指出动词的执行者等。因此很多被动语态没有由by引出的宾语。如: People may lose their lives and homes or they may be injured badly in a fire. 在大火中人们可能失去性命和家园,要不就是严重烧伤。 It is used for protecting the fireman from smoke. 它用来保护消防人员以避免吸进烟雾。 4.在主动语态变为被动语态时,时态一般应保持一致。如: We will build more factories in my hometown. → More factories will be built in my hometown. 我们家乡将要建起更多的工厂。
为此,我们必须记住以下某些时态的被动结构: do(es)→ is/am/are done did → was/were done have/has done → have/has been done will do → will be done be doing → be being done
5.某些动词可以跟双宾语如give、pass、bring、write;buy、make等,在变为被动语态时如果直接宾语变为被动语态中的主语,则间接宾语通常由介词to、for引出。例如: My sister gave me a nice watch for my birthday. → A nice watch was given to me by my sister for my birthday. 我过生日时收到了姐姐的一块手表。 They have bought us many books. → Many books have been bought for us by them. 很多书都是由他们给我们买的。 6.某些动词make、hear、see、watch等在主动语态中,其宾语补足语要求用不带to的不定式。但在变为被动语态时通常省略的不定式符号to必须恢复。如: He made us clean the classroom after school. → We were made to clean the classroom after school. 我们被迫在放学后打扫教室。 I saw him come into the room. → He was seen to come into the room. 人们看见他进了屋子。 7.在主动语态中如果谓语动词是含有介词或副词的短语动词,变为被动语态时不能丢掉该介词或副词。如: They must take good care of the children. → The children must be taken good care of. 孩子们必须小心照看。 8.英语中某些动词如sell、lock、draw、start等在否定句、进行时或用在某些形容词、副词前可以表示被动意义。如: This kind of books sells well. 这种书畅销。 The door won’t lock. 门锁锁不上。
『肆』 初中英语改被动语态
1. The indicient is being talked about by people all over the town.
2. A bus was seen running toward us at the time.
3. She was elected leader of the group.
4. The sports meet had to be put off by them because of the rain.
5. It doesn't have to be written in such a hurry.
『伍』 初中英语被动语法（喧宾夺主）The soup will taste delicious again.
The soup will taste delicious again.
taste（尝起来）是系动词抄，是主动形式表被动意义。
由实义动词转化而来的系动词都是主动形式表被动意义。如：look（看起来），sound（听起来），smell（闻起来），feel（摸起来）。例句：
It looks nice.
It smells sweet.
The coat felt smooth.
The story sounds interesting.
还有一些动词不是系动词，但也以被动主用。如：
The coat washes easily.（这件衣服好洗。）
The books sell well.（这些书好卖。）
The pen writes smoothly.（这支钢笔写起来很流畅。）
这种动词被动主用的共同特点是：它们并不是真的有动作，它们只是表达主语的某种特点。如例1，这里并没有“洗”这个动作，只是表示这件衣服的特点是“好洗”。试比较：
The coat was washed by me yesterday. （这件衣服是我昨天洗的。）这里有“洗”这个动作，所以不能被动主用。

在主动句中,主语作为动作的执行者：Masked thieves stole a valuable painting from the museum last naght.（昨天夜里蒙面窃贼从博物馆里盗走了一幅价值连版城的油画权.）

被动语态由助动词be+动词过去分词构成：Museum security to be improved.（博物馆安全有待加强）
『捌』 求初中英语被动句用法
主语和宾语换个位置 动词前面加动词 动词变成被动形式（通常后面加ed）
如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。主动语态→被动语态：
1、找到该句宾语（必须是在谓语动词后的），将它提到句子开头。
2、用被动语态结构be+Vt过去分词构成句子。
3、把原句的主语用by构成的介词短语带出，也可不加。
eg：I finished my homework yesterday.
→My homework was finished (by me) yesterday.
特殊形式：
1、部分Vi加上适当介词可当作Vt构成被动语态。
eg：Parents look after their children carefully.
→Children were looked after (by parents) carefully.
2、联系动词没有被动语态。eg：The water feels warm.
3、在主动语态中一些省略to的动词不定式改为被动语态时需加上to。
eg：Teachers often make him stand outside.
→He is often made to stand outside (by teachers).
4、have、let等动词无被动语态。
必要时，have可改为held，let sb to do sth可改为be allowed to do sth (被允许做某事
