關(guān)鍵詞:語態(tài)被動語態(tài)時(shí)態(tài)

顧俊萍

被動語態(tài)是兩大語態(tài)之一,也是各類考試命題的熱點(diǎn)。在現(xiàn)階段,同學(xué)們首先要——

了解使用場合

1.行為主體不明確,不必說出或者無法說出動作的執(zhí)行者時(shí)。例如:

Basketball is played all over the USA.

2.不易找到或根本就不可能找到動作的執(zhí)行者時(shí)。例如:

——My new bike was stolen.

一Im sorry to hear that

3.漢語中含有“被”、“由”等詞時(shí)。例如:

Simon iS asked to come by orr Enelish teacher.

4.漢語中沒有“被”、“由”等詞,而在原句中加這類詞且句意通順時(shí)。例如:

These songs are usually sung by girls.

5.漢語中含有“據(jù)說”、“據(jù)悉”、“有人說”、“大家說”等時(shí)。例如:

Itis said that the old man can still eat three bowls Ofrice for lunch at the ageof 75.

6.某些句子習(xí)慣上用被動語態(tài)。例如:

MycousinWas bornOn October 1st,1999.

7.表示禮貌時(shí)。例如:

You are invitedtOcometOoureveningparty at6:00p.m.tomorrow.

了解了被動語態(tài)的使用場合,同學(xué)們還需要——

掌握基本結(jié)構(gòu)

be動詞在被動語態(tài)中只算作助動詞,總管一切變化,如人稱、數(shù)、否定、疑問、時(shí)態(tài)等。

請看下表:

通過上表,同學(xué)們可以將此前所學(xué)的五大時(shí)態(tài)和被動語態(tài)知識有機(jī)地結(jié)合起來,從而達(dá)到將所學(xué)知識系統(tǒng)化的效果。

注意:被動語態(tài)中過去分詞后介詞可用by,也可用with。一般地,表示動作的施動者(某人)或施動力(某物),當(dāng)其原則上是行為者時(shí)之前用介詞by;當(dāng)其是工具時(shí)之前用with。但有時(shí)可把物比作人,把人比作物。體會:

The model plane Was made by him.

The street is crowded with people on New Years Day·

元旦街上擠滿了人。(把人比作物)

The wooden house is surrounded by flowers.

木房周圍都是花。(把物比作人)

被動語態(tài)是初中英語的重點(diǎn),而將主動語態(tài)變成被動語態(tài)又是其難點(diǎn)。在此向同學(xué)們介紹一種簡便方法。

一變二同三注意

一、變。即把主動語態(tài)中的賓語變?yōu)楸粍诱Z態(tài)的主語;主動語態(tài)中的謂語動詞變?yōu)閎e+過去分詞;主動語態(tài)中的主語變?yōu)榻樵~by的賓語,放在謂語動詞后面(如果不強(qiáng)調(diào)動作的執(zhí)行者,by短語??墒÷?;其它成分不變。如:

They plant trees every year.

主語謂語賓語(主動語態(tài))

Trees are planted by them every year.

主語謂語(被動語態(tài))

二、同。主動語態(tài)的謂語動詞是什么時(shí)態(tài),變成被動語態(tài)后還是什么時(shí)態(tài),即助動詞be的時(shí)態(tài)要跟原主動語態(tài)的時(shí)態(tài)相同。如:

1.一般現(xiàn)在時(shí):am/is/are+過去分詞。例如:

Theybuyapples everyweek.

→Apples are bought by them every week.

2.一般過去時(shí):was/were+過去分詞。例如:

A policeman saved the little gur1.

→The little girl was saved by a policeman.

三、注意。主動語態(tài)在變?yōu)楸粍诱Z態(tài)時(shí)要注意以下幾點(diǎn):

1.含有雙賓語的主動句變成被動句時(shí),通常把指“人”的間接賓語變?yōu)橹髡Z,指“物”的直接賓語保留不變。例如:

My parentsgavenle anewcalnerfiyesterday.

→IWasSiVeilailewcamerabymyparentsyesterday·

如果要把指“物”的直接賓語變?yōu)橹髡Z,則在間接賓語前加to或for。例如:

AnewcameraWasSiveil to Omebymyparentsyesterday

2.含有復(fù)合賓語的主動句在變?yōu)楸粍泳鋾r(shí),將其中的賓語變成主語,賓語補(bǔ)足語不變。例如:

Wefound Peteraverycleverboy.

→PeterWasfoundaverycleverboybyus.

但是,如果賓語補(bǔ)足語是不帶to的動詞不定式,主動語態(tài)變成被動語態(tài)時(shí)要加上不定式符號to。例如:

TheteachermakeshimreadEngisheverymorning。

→HeiSmadetoreadEnglish Shbytheteachereverymorning.

3.如果主動句中的謂語動詞是一些相當(dāng)于及物動詞的短語動詞,變?yōu)楸粍泳鋾r(shí)短語動詞中的介詞或副詞不可以丟掉。例如:

HetookgoodcareOfyourcat.

→YourcatwastakengoodcareOfbv him

學(xué)習(xí)了以上知識點(diǎn)之后,同學(xué)們可以通過精練以下典型試題來檢測一下學(xué)習(xí)的效果。
