`-` Cấu trúc câu bị động chỉ ý kiến:

`->` CĐ: S `+` say/believe/think/ ... (chia) `+` that `+` S2 `+` V2 (chia)

`=` BĐ: It `+` be said/believed/thought/ ... `+` that `+` S2 `+` V2(chia)

`=` S2 `+` be said/believed/thought/ ... `+` to V/to have PII

`@` Chú ý: Nếu vế `2` ở thì QKĐ, hoặc khác thì ở cả `2` vế khi chuyển sang câu bị động bằng cách `2` thì sau "to" ta thêm "have PII".

`-` Nếu ở mệnh đề `2` ở câu chủ động là bị động ta có cấu trúc của `C2:`

`->` S2 `+` be said/believed/thought/ ... `+` to be PII/to have been PII

`@` Lưu ý: Trong câu chủ động với các chủ ngữ “I, They, We, somebody, someone,everybody, everyone,....” thì khi chuyển sang câu bị động ta bỏ By O.

`+` By O đứng trước trạng từ chỉ thời gian và đứng sau trạng từ chỉ nơi chốn.
