一般現在時的被動語態
在英語中，動詞有兩種語態，即主動語態和被動語態。被動語態的基本結構是“助動詞 be + 及物動詞的過去分詞”，其中助動詞be有人稱、數和時態的變化，其變化規則與be作為連系動 完全一樣。
一般現在時被動語態的基本用法
表示經常性或習慣性發生的被動動作
I am often asked the question by my pupils.
表示近期正在發生的被動動作
These days people are moved by a teacher named Zhang Lili.
描述某種常態化的被動的客觀事實
The spaceship is mainly controlled by computer.
強調目前存在的針對行為主體人的被 限制性動作
You aren’t allowed to take photos.
主動語態變為被動語態的方法
第一步：將主動語態的賓語改為被動語態的主語；
第二步：將主動語態的謂語改為“be+及物動詞的過去分詞“結構；
第三步：將主動語態的主語改為介詞by的賓語，放在謂語之后（有時可省略）。
把下列的主動句變為被動句。
1. People play football all over the world.
Football is played all over the world by people.
2. The old man on TV tells a story on Sunday.
