 CHUYÊN ĐỀ 1: THÌ VÀ SỰ HOÀ HỢP THÌ 
Phần lý thuyết:
 Dạng 1: Chia động từ dựa vào trạng từ nhận biết
 Ở dạng này, các em phải nắm vững những dấu hiệu về thì dựa theo cách dùng hoặc những 
 trạng từ nhận biết và điều quan trọng là các em phải thuộc công thức của các thì cơ bản trong Tiếng 
 Anh. 
 VD1: Cho hình thức đúng của đông từ trong ngoặc:
 1. Water boils (boil) at 1000C. => dùng thì HTĐ, diễn tả một sự thật hiển nhiên.

 gian đi với:
 WHEN: Khi đó UNTIL: cho đến khi = TILL
 WHILE: Trong khi AS SOON AS: ngay khi
 BEFORE: Trước khi = BY THE TIME SINCE: kể từ khi

 - Xác định ngữ cảnh trong câu xem những hành động này xảy ra ở QK , HT, hay TL
 - Xác định trong câu có những trạng từ chỉ thời gian gì
 - Tiến hành phối hợp thì theo quy tắc riêng của nó:
 1. Ngữ cảnh ở QK: (thường các em sẽ gặp những trạng từ như YESTERDAY, LAST NIGHT, 
 AGO... hoặc một động từ đã được chia ở thì QK)
 when + QKĐ, QKTD ; QKTD + when + QKĐ : QKĐ + when + QKTD
 VD1: We were having supper when the phone ran
 while + QKTD, QKĐ ; QKĐ + while + QKTD ; QKTD + while + QKTD

 Before/ by the time + QKĐ, QKHT ; QKHT + before/by the time + QKĐ

 VD4: After I had finished work, I went out with my friends.
 2. Ngữ cảnh ở tương lai: (thường các em sẽ gặp những trạng từ như TOMORROW, NEXT 
 WEEK, NEXT MONTH... hoặc một động từ được chia ở thì tương lai)
 S +will / shall /may /can.....+ when /until / as soon as / before... + HTĐ / HTHT
 VD1: I will wait here until they come 
 VD2: After I get home, I will eat dinner
 Lưu ý: HTHT + since + QKĐ ; Since + QKĐ, HTHT

 1 * Đại từ bất định (everyone, something, nobody) => chia ĐT số ít. Ví dụ : Everybody is in the room.
