主動句與被動句之間的轉換Somebooks

werebought(byus)

主語謂語動詞主動語態的過去式賓語主語謂語動詞被動語態的過去分詞介詞+賓語主動句變為被動句所遵循的4個步驟：1.把原主動句中的賓語變為被動句的主語。2.把動詞變為被動形式即be+過去分詞，并注意其人稱和數隨主語的變化，而動詞的時態則保持不變。3.原主動句的主語如需要則放在by后面以它的賓格形式出現（注代詞的賓格），如不需要則可省略。4.其它的成分（定語、狀語）不變。被動語態的幾種句型

肯定句

主語+be+過去分詞+(by…)Asweetsongwassungbyheronthestage.2否定句

主語+be+not+過去分詞+(by…)3一般疑問句

Be+主語+過去分詞+(by…)?Asweetsongwasn’tsungbyheronthestage.Wasasweetsongsungbyheronthestage?4特殊疑問句

疑問詞+be+主語+過去分詞+(by…)?Wherewasasweetsongsungbyher?一般講，被動語態可用于英語的各種時態。為了能準確地運用被動語態，重點是要掌握be動詞的各種時態變化。各種時態的被動語態舉例如下：

1、一般現在時的被動語態：am/is/are+動詞的過去分詞

Ourclassroomiscleanedeveryday.ThiscarismadeinChina.

2、一般過去式的被動語態:was/were+

動詞的過去分詞

Hisdeskwascleanedjustnow.

Thestationwasbuiltin1928.

一般現在時：am/is/are+vt.p.p.

一般過去時：

was/were+

vt.p.p.

一般將來時:

willbe/begoingtobe+

vt.p.p.

情態動詞：must/can/could/may+be+

vt.p.p.現在進行時:

be(am/is/are)+being

+

vt.p.p.現在完成時:

have/has+been

+

vt.p.p.被動語態的構成：be

+vt.p.p.被動語態：當我們不知道誰是動作的執行者，或者沒有必要指出誰是動作的執行者時，或者只需強調動作的承受者時，要用被動語態。何時使用被動語態？何時使用被動語態？主語是動作的承受者。
