he didn’t know anything until he was 3 years old => it was not ……… => not until ………

1 bình luận về “he didn’t know anything until he was 3 years old => it was not ……… => not until ………”

1. Answer : It was not until he was 3 years old that he knew something. – Not until he was 3 did he know something.

   – It + be + not until + time/clause + that + S + V (chia cùng thì với vế trước): mãi cho đến khi …. thì ….

   – Đảo ngữ: Not until + time/clause + trợ động từ + S + V (nguyên dạng): mãi cho đến khi …. thì ….

   – Câu này được chia ở QKĐ -> trợ động từ là did 

   – “not until” đã mang nghĩa phủ định rồi nên anything thành something.
