ghi luôn hộ e sửa thành gì với ạ Choose the underlined word or phrase in each sentence that needs correcting. Jen was really mad at her friends, she wanted to know what were they doing. A. mad at B. wanted C. to know D. were they

Đáp án: D-> they were

Giải thích: Vế từ "she wanted to know...." là câu gián tiếp với Wh_question: S1+ wanted to know+ wh_question+ S2+ V(lùi thì)

- Sau wh_quesiton là "what" là chủ ngữ-> đảo "they" lên trước "were", rồi mới đến từ "were".
