三、語法：
被動語態(tài)。
核心知識
1．語法：被動語態(tài)。
英語中有主動和被動兩種語態(tài)。主動語態(tài)中主語是動作的執(zhí)行者；被動語態(tài)中主語是動作的承受者。
e．g： We speak English. (主動句)
執(zhí)行者
English is spoken by us. (被動句)
承受者
(1)被動語態(tài)的謂語構(gòu)成：be+過去分詞
注意：①若要保留原來動作的執(zhí)行者，則將其放在介詞by之后。(見上例by us)
②不及物動詞無被動語態(tài)形式。
③be隨句子時態(tài)的變化而變化。
(2)被動語態(tài)的用法：當不知道動作的執(zhí)行者或沒有任何必要指出動作的執(zhí)行者，而需要強調(diào)動作的承受者時，使用被動語態(tài)。
e．g： English is widely used by people all over the world.
(3)當主動語態(tài)改為被動語態(tài)時，若主動句中有兩個賓語，則可把其中任意一個賓語作為被動句的主語。
e．g： Mother gives me a present. (主動)
I am given a present by mother. (被動)
A present is given to me by mother. (被動)
2．be made of/from/in與be made up of.
(1)be made of：“由……制成”，原材料一般是未經(jīng)化學(xué)變化，仍可看出原材料。
e．g; The house is made of stone. 房子是石頭建的。
(2)be made from：“由……制成”；制成品看不出原來的材料。
Paper is made from wood. 紙是由木材制成的。
(3)be made in：“在某地制造”。
The car is made in China. 這輛車產(chǎn)于中國。
注意區(qū)分：be made up of：“由……組成”
The team is made up of five students.
這個小組由五個學(xué)生組成。
3．be used for/be used as, 與be used by.
(1)be used for：“被用于做”for表用途，后接名詞或動名詞。
e. g：It’ s used for locking doors. 它是鎖門用的。
(2)be used as：“把……當作”
The box can be used as a table. 這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語。
4．a(chǎn) number of：“許多，大量”，后接可數(shù)名詞復(fù)數(shù)。a lot of, many.
e. g：I have a number of books. 我有許多書。
注意區(qū)分： the number of： “……的數(shù)量／號碼”
e. g：The number of the students in our school is five hundred.
我們學(xué)校學(xué)生人數(shù)有500人。
5．none與neither.
none代詞：“…中沒有一個”。一般指三者或三者以上都不是all的反義詞。
e. g：We are all very tired, but none of us stop to have a rest.
我們都很累，但沒有一個人停下來休息。
neither：代詞。“兩者中沒有一個”，是both的反義詞。
e. g：Neither of my parents in at home.
我父母都不在家。
6．quarters：四分之三
英語中分數(shù)的表達方法：分子用基數(shù)詞，分母用序數(shù)詞，分子大于1時，作分母的序數(shù)詞用復(fù)數(shù)。
1/2：a half
1/3：one third
1/4：one quarter
3/4：three quarters
2/5：two fifths
