Dùng mệnh đề quan hệ nối hai câu:
This watch is a gift. the watch was given to me by my aunt on my 14th birthday.
Nối cách nào đúng ạ?
This watch, which was given to me by my aunt on my 14th birthday, is a gift.
This watch is a gift which was given to me by my aunt on my 14th birthday
Câu đúng là: This watch, which was given to me by my aunt on my 14th birthday, is a gift.
Câu kia mình thấy cũng đúng nhưng thường thì mình thấy relative pronouns sẽ đứng sau chủ ngữ.
