主語謂語動詞主動語態(tài)的過去式賓語主語謂語動詞被動語態(tài)的過去分詞介詞+賓語主動句變?yōu)楸粍泳渌裱?個步驟：1.把原主動句中的賓語變?yōu)楸粍泳涞闹髡Z。2.把動詞變?yōu)楸粍有问郊碽e+過去分詞，并注意其人稱和數(shù)隨主語的變化，而動詞的時態(tài)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(xiàn)（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(tài)的幾種句型

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(tài)可用于英語的各種時態(tài)。為了能準(zhǔn)確地運用被動語態(tài)，重點是要掌握be動詞的各種時態(tài)變化。各種時態(tài)的被動語態(tài)舉例如下：

1、一般現(xiàn)在時的被動語態(tài)：am/is/are+動詞的過去分詞

Ourclassroomiscleanedeveryday.ThiscarismadeinChina.

2、一般過去式的被動語態(tài):was/were+

動詞的過去分詞

Hisdeskwascleanedjustnow.

Thestationwasbuiltin1928.

一般現(xiàn)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(tài)動詞：must/can/could/may+be+

vt.p.p.現(xiàn)在進(jìn)行時:

be(am/is/are)+being

+

vt.p.p.現(xiàn)在完成時:

have/has+been

+

vt.p.p.被動語態(tài)的構(gòu)成：be

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