國中英語知識重點1. 被動語態的.基本時態變化
被動語態通常爲十種時態的被動形式, 被動語態由be+過去分詞構成，be隨時態的變化而變化。以do爲例，各種時態的被動語態形式爲：
1) am/is/are +done (過去分詞) 一般現在時
例：Visitors are requested not to touch the exhibits.
2) has /have been done 現在完成時
例:All the preparations for the task have been completed, and we're ready to start.
3) am/is /are being done 現在進行時
例:A new cinema is being built here.
4) was/were done 一般過去時

例:His mother gave him a present for his birthday. 可改爲 He was given a present by his mother for his birthday.
3) 當“動詞+賓語+賓語補足語”結構變爲被動語態時，將賓語變爲被動結構中的主語，其餘不動。
例:Someone caught the boy smoking a cigarette. 可改爲The boy was caught smoking a cigarette.

例:Someone saw a stranger walk into the building. 可改爲A stranger was seen to walk into the building.
5) 有些相當於及物動詞的動詞詞組，如“動詞+介詞”，“動詞+副詞”等，也可以用於被動結構，但要把它們看作一個整體，不能分開。其中的介詞或副詞也不能省略。
例The meeting is to be put off till Friday.
