IV、重點語法
被動語態(tài)：英語動詞有兩種語態(tài)：主動語態(tài)和被動語態(tài)。主動語態(tài)表示主語是動作的執(zhí)行者，被動語態(tài)表示主語是動作的承受者。如：
He answers the questions in public.?（主動語態(tài)）
The questions are answered in public.?（被動語態(tài)）
被動語態(tài)各時態(tài)構(gòu)成表
TENSE主動語態(tài)被動語態(tài)
一般現(xiàn)在時be / V / Vsam / is / are +Vpp
一般將來時Will +Vwill be +Vpp
現(xiàn)在進行時am / is / are +Vingam / is / are + being + Vpp
一般過去時①was / were/?②Vedwas / were+ Vpp
一般完成時have / has + Vpphave / has + been + Vpp
過去完成時had + VppHad + been + Vpp
過去進行時was / were +Vingwas / were+ being +Vpp
情態(tài)動詞Can +VCan + be +Vpp
1、用法
�。�1）不知道誰是動作的執(zhí)行者或沒有必要，如：
Paper is made from wood.
�。�2）需要強調(diào)動作的承受者時，如：
Books and newspapers in the reading room mustn’t be taken away.
（3）為了使語氣婉轉(zhuǎn)，或由于修飾的需要
Electricity is used to run machines.
2、主動語態(tài)和被動語態(tài)的轉(zhuǎn)換
�。�1）把主動語態(tài)的賓語改為被動語態(tài)的主語
�。�2）把主動語態(tài)的謂語動詞改為相應的被動語態(tài)的結(jié)構(gòu)
�。�3）把主動語態(tài)的主語改為“by+原主語（主格變賓格）”，放在主謂結(jié)構(gòu)之后,在意思明確時by短語可以省略。
We speak English.→English is spoken by us.
3、需注意的幾點：
�。�1）只有及物動詞有被動語態(tài)，不及物動詞沒有被動語態(tài)。
�。�2）含有雙賓語的句子由主動語態(tài)變?yōu)楸粍诱Z態(tài)時有兩種情況：
A、把間接賓語改為被動語態(tài)的主語，直接賓語仍留在原位。
B、把直接賓語改為被動語態(tài)的主語，此時，間接賓語前要加介詞to或?for。如：She gave the boy a book.→The boy was given a book.或The book was given to the boy.
�。�3）短語動詞是不可分割的整體，改為被動語態(tài)時，要保持其完整性，介詞或副詞不可漏掉。這樣的短語有：look after, listen to, look at, pay attention to, take care of, look forward to, make use of ,etc.?如：
You must take care of your dog.→Your dog must be taken care of.
�。�4） 主動句中在感官動詞see, look at, hear, listen to, feel, watch, notice及使役動詞make, let, have等動詞后應跟不帶to的動詞不定式,而在被動句中應加上不定式符號to。如：I saw Tom enter the room.→Tom was seen to enter the room.
�。�5）有些被動語態(tài)結(jié)構(gòu)成了習慣用法。例如：
It is said that… 據(jù)說… It is(was) reported that…據(jù)報道…
It is well-known that… 眾所周知…
4、主動形式表被動意義的情況
�。�1）動詞need后接v-ing的主動結(jié)構(gòu)常表被動意義。例如：
The desk needs mending.
�。�2）open, lock, sell, read, write, clean, cut, wash, burn, teach, drive, shut等及物動詞在用作不及物動詞時，它們的主語為物，可用主動語態(tài)表被動意義。例如：
The car drives well.
�。�3）look, taste, smell, seem, sound等連系動詞主動形式表示被動意義。例如：
The dish tastes good.
5、被動語態(tài)與系表結(jié)構(gòu)的區(qū)別
“be+過去分詞”形式在句子中可能是一個被動語態(tài)的謂語，也可能是一個系表結(jié)構(gòu)的謂語。對于它們的區(qū)別主要從它們表達的意義上看，而不是從形式上看。系表結(jié)構(gòu)中的過去分詞是表示主語的特征或狀態(tài)，而被動結(jié)構(gòu)則是表示主語是動作的承受者。例如：
The door is closed at nine every day.（行為，被動結(jié)構(gòu)）
The door is closed now.（狀態(tài)，系表結(jié)構(gòu)）
The letter was written yesterday.（行為，被動結(jié)構(gòu)）
The letter is written in English.（狀態(tài)，系表結(jié)構(gòu)）
V、書面表達
1.談論允許和不允許的事情或者應該被允許和不應該被允許的事情。P22 3a
如：
�。�1）My family / school / class rules
�。�2）Rules in the library
�。�3）Talk about something in your food, health, study, hope or something else.
2.談論某物的發(fā)明及用途。P72 3a
范文：假如你班要召開一次以“keep our school clean”為主題的班會，請就同學們應該或不應該做的事情寫一篇簡短的發(fā)言稿，例如“不允許在墻上亂涂亂畫，應該每天打掃教室”等。
Good afternoon, everyone!
We are studying in this school. It’s our duty to keep it clean and tidy. So we have made some school rules. We cannot spit in public places, such as in the library and in the classroom. We are not allowed to draw pictures on the walls and throw any litter onto the ground. We should clean the classroom every day. If everyone tries to do something useful for our school, I’m sure our school will be more and more beautiful.
That’s all , thank you.
