Giải thích:

Ta có cấu trúc câu bị động ở các thể:

`+` Modal verbs:S + modal verb + be + V_ed/V3+....

`+` Thì hiện tại hoàn thành: S + has/have + been + V_ed/V3 +....

`+`Thì hiện tại tiếp diễn: S + am/is/are + being + _ed/V3 +.....

`+` Thì quá khứ tiếp diễn: S + was/were + being + V_ed/V3 +.......

Với S ở chủ động tên người cụ thể thì ta đưa "by" vào câu bị động,nếu là chung chung(they,he,...)thì ta bỏ "by"
