三、语法：
被动语态。
核心知识
1．语法：被动语态。
英语中有主动和被动两种语态。主动语态中主语是动作的执行者；被动语态中主语是动作的承受者。
e．g： We speak English. (主动句)
执行者
English is spoken by us. (被动句)
承受者
(1)被动语态的谓语构成：be+过去分词
注意：①若要保留原来动作的执行者，则将其放在介词by之后。(见上例by us)
②不及物动词无被动语态形式。
③be随句子时态的变化而变化。
(2)被动语态的用法：当不知道动作的执行者或没有任何必要指出动作的执行者，而需要强调动作的承受者时，使用被动语态。
e．g： English is widely used by people all over the world.
(3)当主动语态改为被动语态时，若主动句中有两个宾语，则可把其中任意一个宾语作为被动句的主语。
e．g： Mother gives me a present. (主动)
I am given a present by mother. (被动)
A present is given to me by mother. (被动)
2．be made of/from/in与be made up of.
(1)be made of：“由……制成”，原材料一般是未经化学变化，仍可看出原材料。
e．g; The house is made of stone. 房子是石头建的。
(2)be made from：“由……制成”；制成品看不出原来的材料。
Paper is made from wood. 纸是由木材制成的。
(3)be made in：“在某地制造”。
The car is made in China. 这辆车产于中国。
注意区分：be made up of：“由……组成”
The team is made up of five students.
这个小组由五个学生组成。
3．be used for/be used as, 与be used by.
(1)be used for：“被用于做”for表用途，后接名词或动名词。
e. g：It’ s used for locking doors. 它是锁门用的。
(2)be used as：“把……当作”
The box can be used as a table. 这只箱子可以做桌子用。
(3 be used by： by：“被(sb)使用”
e．g： English is used by people all over the world. 全世界的人都使用英语。
4．a number of：“许多，大量”，后接可数名词复数。a lot of, many.
e. g：I have a number of books. 我有许多书。
注意区分： the number of： “……的数量／号码”
e. g：The number of the students in our school is five hundred.
我们学校学生人数有500人。
5．none与neither.
none代词：“…中没有一个”。一般指三者或三者以上都不是all的反义词。
e. g：We are all very tired, but none of us stop to have a rest.
我们都很累，但没有一个人停下来休息。
neither：代词。“两者中没有一个”，是both的反义词。
e. g：Neither of my parents in at home.
我父母都不在家。
6．quarters：四分之三
英语中分数的表达方法：分子用基数词，分母用序数词，分子大于1时，作分母的序数词用复数。
1/2：a half
1/3：one third
1/4：one quarter
3/4：three quarters
2/5：two fifths
