如何將主動語態變成被動語態？

1、從句子意義上說，就是重新找出“什麼事物”是“被完成”的。

例1.

主動語態：人們說英語。

被動語態：英語被說。　

English is spoken in many countries..

例2.

主動語態：我們造這座橋。

We built this bridge last year.

被動語態：這座橋被建造。

This bridge was built last year.

2、從語法的角度說，把原句的賓語改成主語。

例1.

主動語態：小王邀請你(賓語)

Xiao Liu has invited you to a lunch party.

被動語態：你(賓語)被邀請。

You has been invited to a lunch party by Xiao Wang.

例2.

主動語態：你不准帶走雜志(賓語)

You must not take these magazines out of the reading-room.

被動語態：雜志(賓語)不准被帶走.

These magazines must not be taken out of the reading room.

例3.
