1、 人教版2019年九年级初中英语知识归纳总结（第五部分）：被动语态、非谓语动词学生姓名： 年 级： 老 师： 上课日期： 时 间： 课 次： 第二十二课时 被动语态（一）教学重点被动语态在英语中，须通过动词的某种形式来表明句子的主语是动作的执行者还是动作的承受者，前一种句子是主动句，后一种是被动句。英语的动词有两种语态形式，即主动语态和被动语态。如果主语是动作是执行者，谓语动词用主动语态。如果主语是动作的对象，谓语动词用被动语态。如：They build this school.They school is built by them.1、被动语态的构成“助动词 +（及物动词的）过去分词”构成
2、动词被动语态的形式。助动词be有人称、数和时态的变化，其变化规则与be作为系动词的变化完全一样。如：This kind of TV set is made in Guangzhou.（一般现在时）The thief was arrested.（一般过去时）A new road is being built outside my house.（现在进行时）The man was being questioned by the police.（过去进行时）Your wallet has been found.（现在完成时）By the time we got there. The work had
3、 been finished.（过去完成时）My sister would be taken care of by grandma.（过去将来时）Your watch will be repaired.（一般将来时）教学难点：在英语里，有一些动词是不及物动词，后面不能跟宾语，所以没有被动语态。以下动词只有主动语态，没有被动语态。appear, die, happen, fall, arrive.2、五种时态的被动语态举例 一般现在时A lot of books are kept in our school library.Radio is used in everyday life. 一般过去
4、时A thief was caught last night.They were asked to speak at the meeting. 现在进行时A new library is being put up in their school now.The watch is being repaired. 一般将来时The class meeting will be held next Saturday afternoon.The thieves will be arrested. 现在完成时My bag has been stolen.Many stamps have been coll
5、ected by me since last year.3、主动语态变被动语态 主动结构的宾语变为被动结构的主语。 主动结构的谓语动词由主动语态变为被动语态。 主动结构的主语变为介词by的宾语，组成介词短语，放在被动结构中谓语动词之后。在动作的执行者无须说明或不必强调时，by短语可以省略。 主动语态、被动语态两种时态要保持一致。如：We repaired the motor.The motor was repaired by us.第二十三课时 被动语态（二）教学重点被动语态（二）几种不同形式的被动语态（1）含有直接宾语和间接宾语的主动结构，变为被动结构时，可以将其中一个宾语变为主语，另一个不
6、动，一般是主动结构的间接宾语变为被动结构的主语，这样句子显得自然一些。如：He showed me his pictures.I was shown his pictures by him.I was sent a birthday present (by him).A birthday present was sent to me (by him).（2）含有复合宾语的主动句变为被动句的方法。 将宾语变为主语，宾语补足语保留不动。如：They call her little Li.She is called little Li.He left the door open.The door w
7、as left open by him. make, let, hear, watch, see, feel, have, notice, help等动词后面作宾语补足语的不定式一般不带to，可是当变为被动语态时，后面的不定式必须带to。如：My brother often made me do this and that when I was young.I was often made to do this and that by my brother when I was young. 含有情态动词的被动语态，是由“情态动词 + be +（及物动词的）过去分词”构成。如：They can
8、 not find him.He can not be found. 短语动词的被动语态一般说来，只有及物动词才有被动语态，因为只有及物动词才可能有动作的承受者。但有许多由不及物动词加介词及其他词类构成的短语动词，相当于及物动词，可以有宾语，因而也可以有被动语态。但应注意，短语动词是一个不可分割的整体，在变为被动语态时，不可丢掉构成短语动词的介词或副词。如：They had put out the fire before the fire brigade arrived.The fire had been put out before the fire brigade arrived.They
9、 will set up a new public school here.A new public school will be set up here.You must take good care of these trees.These trees must be taken good care of.被动语态的基本用法 不知道谁是动作的执行者或者没有必要指出谁是动作的执行者时。如：Paper is made from wood.The house is quite old, it was built in 1950.He was wounded in the fight. 需要强调动
10、作的承受者时。如：Calculator cant be used in the maths exam.Books and newspapers in the reading room mustnt be taken away.He was awarded first prize in that contest. 为使语气婉转，避免提及自己或对方而使用被动语态，或由于修辞的需要使用被动语态使句子得以更好安排。如：The construction of the new lab must be completed by the end of next month.Electricity is use
11、d to run machines.第二十四课时 非谓语动词（一）教学重点动词不定式 在英语中，不充当句子谓语的动词，叫作非谓语动词。由于非谓语动词不受主语的限制，没有时态和语态，所以又叫非限定动词。非限定动词有三种形式：动词不定式；动名词和分词。1、动词不定式（1）动词不定式的构成和性质动词不定式是一种非谓语动词，所谓非谓语动词就是不能作谓语的动词。正因为如此，它不受主语的人称和数的限制，没有人称和数的变化，但它具有动词的某些特征，可以带宾语和状语构成不定式短语。其构成是：“to + 动词原形”，否定式是“not to +动词原形”。to是不定式符号，无词义。（2）动词不定式的用法动词不定式
12、除了不能作谓语外，可以作主语、表语、宾语、宾语补足语、定语和状语。 作主语To learn English well is not easy.To drive fast is quite dangerous.不定式作主语时常常用it作形式主语，不定式放在谓语之后以上两个例句可以写成：It is not easy to learn English well.It is quite dangerous to drive fast.这种用法可以归纳成这样一个句型：It is (not) + 形容词 + (for sb.) to do sth.It is very expensive for me t
13、o buy a car.It is very difficult for a child to do that job.有些形容词之后跟of + 名词（代词宾语）+不定式。如：It is very kind of you to say so.It is very good of you to come. 作表语。如：My job is to teach English.The first thing is to ring him up. 作宾语。如：She wanted to ask you a question.He forgot to turn off the light.We decid
14、ed to hold a class meeting.常见的可以用不定式作宾语的动词有：like, love, begin, start, try, ask, prefer, hate, find等，有些形容词可接不定式，这种不定式也可作宾语。如：Im very glad to see youHes sure to come. 作宾语补足语不定式是用来补充说明宾语的，通常不定式的动作是宾语发出的。可以带不定式作宾补的动词有：ask sb. To do sth. want sb. To do sth.tell sb. To do sth. like sb. To do sth. help sb. (to) do sth.，还有些动词可以跟省略to的不定式作宾语补足语。如：hear, watch, see, feel, make, let, have等。如：I often help my mother do housework.The policeman asked the driver to stop.The teacher asked us not to talk in classI want you to buy so
