Giải thích:

     Mình thấy trong bài có vài dạng thì bị động thôi.

Có must, may, can,...: must, may,... + be + V3

Là thì hiện tại tiếp diễn: am/is/are + being + V3

Là thì hiện tại đơn: am/is/are + V3

Là thì quá khứ đơn: was/were + V3

     Sau phần chính thì ta sẽ có "by + someone" để nói về ai làm việc đó, trong trường hợp chủ ngữ trong câu chủ động là những từ chung chung (we, they, people, ...) thì có thể lược bỏ.

     Trạng từ (thời gian, vị trí,...) luôn nằm ở cuối câu, đằng sau vế "by+someone" nếu có.
