1、被動語態:主動語態表示主語是動作的執行者。例如：Many people speak English.謂語：speak的動作是由主語many people來執行的。當句子的主語和謂語動詞之間構成被動的意思，一般情況下要用被動語態。例如：English is spoken by many people.主語 English 是動詞 speak 的承受者。結構：be + done （動詞過去分詞）不同時態的被動語態的結構：一般現在時：一般過去時：一般將來時：現在完成時：am/ is /are +donewas / were +donewill be done / am/is/are going to

2、 be done has / have been done.主動語態和被動語態的轉換的步驟1）主動語態變被動語態 主語變賓語加by；賓語變主語；對應時態的被動語態He planted a lot of trees in the hills.A lot of trees were planted by him in the hills2）被動語態變主動語態 主語變賓語；賓語變主語，去掉by；對應時態的主動語態 A lot of trees will be planted by them in the hills.They will plant a lot of trees in the hill

3、s.被動語態的注意點(1)在主動語態中，后面跟動詞原形的結構，到了被動語態中要加to, 常見的 make/ let / see/ hear /notice / find +sb +do sthbe made to do / be seen to do / be heard to do / be let to do .He often makes us laugh happily .We are made to laugh happily by him.（2）跟雙賓語的結構，在改被動語態時，如果是人來做主語，其他不變；如果是物做主語，要加介 詞to或是for.He gave me this ma

4、gazine yesterday.-I was given this magazine yesterday.This magazine was given to me yesterday(3)在主動語態中含有固定搭配的詞組，在改被動語態時，介詞是不能少的。She often listens to this song .-This song is often listened to by himThe doctor operated on three patients .Three patients were operated on by the doctor.(4) allow sb to d

5、o sth / tell sb to do sth / ask sb to do sth be allowed to do / be told to do / be asked to do sth常見的不能用于被動語態的詞 一般情況：不及物動詞本身沒有被動語態。如果動詞加上介詞可以跟賓語，如：operate on那么把整個 動詞短語看作及物動詞短語，存在被動語態。He was operated on by an experienced doctor.此外無被動情況：(1)聯系動詞是不能用于被動語態的。The fish smells good./ look , taste , feel, sou

6、nd(2)常考詞無被動情況:happen / take place / come out / run out / rise(3)某些及物動詞可作不及物動詞用，特別是后加副詞(如well, easily等)時。主動語態有被動含 義，這類動詞常見的有sell, write, wear, wash, cook等。如：This kind of radio smells well,這種收音機很暢銷。The cloth washes easily.這種布很容易洗。一、單項選擇。()1.
