Giới thiệu về so sánh bằng

So sánh bằng trong tiếng Anh là cách để chỉ ra sự tương đồng hoặc bằng nhau giữa hai đối tượng hoặc hơn, về tính chất, đặc điểm, hoặc số lượng.  Ngữ pháp so sánh bằng thường xuất hiện trong các câu có một tính từ, trạng từ, danh từ. 

Ví dụ: 

• The car travels at the same speed as the train. (Xe ô tô di chuyển cùng tốc độ như tàu.)
• I have the same amount of money as you. (Tôi có số tiền bằng bạn)
• Her performance in the exam is as good as her friend's (Kết quả bài thi của cô ấy không kém gì bạn cô ấy.)

Công thức so sánh bằng trong tiếng Anh

Có 3 dạng so sánh bằng cơ bản trong Tiếng Anh và một số dạng bài tập mở rộng:

So sánh bằng với tính từ

Công thức cơ bản nhất để tạo nên so sánh bằng với tính từ là sử dụng cụm từ "as...as". Cấu trúc này thường được sử dụng với mục đích thể hiện sự ngang bằng giữa hai đối tượng. 

 

	Cấu trúc khẳng định	Cấu trúc phủ định
Công thức	S1 + V + as + adj + as S2 (+V)	S + be + not + so/as + adj + as + S2 (+V)
Ví dụ	She is as tall as her brother. (Cô ấy cao bằng anh trai của mình)	She is not as tall as her brother. (Cô ấy không cao bằng anh trai mình.) = She is not so tall as her brother

So sánh bằng trong tiếng anh với tính từ

So sánh bằng với trạng từ

So sánh bằng với trạng từ cũng sử dụng cấu trúc "as...as" để chỉ ra sự tương đồng trong cách thực hiện một hành động.

	Cấu trúc khẳng định	Cấu trúc phủ định
Công thức	S1 + V + as + adv + as S2 (+V)	S1 + do/does not + Verb + as + adverb + as + S2
Ví dụ	He runs as quickly as his friend. (Anh ấy chạy nhanh bằng bạn mình.)	He does not run as quickly as his friend. (Anh ấy chạy nhanh bằng bạn mình.)

So sánh bằng trong tiếng anh với trạng từ

So sánh bằng với danh từ

So sánh bằng với cụm “as much/many/little/ few as” 

Khi so sánh bằng với danh từ, chúng ta thường sử dụng "as much/little as" cho danh từ không đếm được và "as many/few as" cho danh từ đếm được.

 

	Cấu trúc khẳng định	Cấu trúc phủ định
Công thức	S + V + as much/many/little/few + N + as + S2	S + do/does not V + as much/many/little/few + N + as + S2.
Ví dụ	She does not have as much freedom as her brother. (Cô ấy không có nhiều tự do bằng anh trai mình.)	He does not have as many opportunities as his colleague. (Anh ấy không có nhiều cơ hội bằng đồng nghiệp của mình.)

 

So sánh bằng trong tiếng anh với danh từ

 

So sánh bằng với cụm “the same…as” 

Công thức "the same...as" được sử dụng khi muốn nhấn mạnh hai đối tượng có chung một đặc điểm hoặc tính chất nào đó.

	Cấu trúc khẳng định	Cấu trúc phủ định
Công thức	S1 + V + the same + (noun) + as + S2	S1 + V + not + the same + (noun) + as + S2
Ví dụ	We have the same interests as they do. (Chúng tôi có những sở thích giống họ.)	This book is not the same as the one you lent me. (Cuốn sách này không giống cuốn mà bạn đã cho tôi mượn.)

 

Mở rộng so sánh bằng trong tiếng Anh

So sánh bằng cụm “Not different…from”

Cụm “different from” được sử dụng để diễn đạt sự khác nhau giữa 2 vật thể, tuy nhiên khi thêm “not” vào trước “different” ta có thể sử dụng để miêu tả sự tương đồng giữa hai đối tượng.

 

	Cấu trúc khẳng định
Công thức	S1 + V+ not different from + S2
Ví dụ	The lemonade that you made was not different from the one I made. ( Ly nước chanh em làm giống với ly của anh làm.)

 

Lưu ý đối với trường hợp viết lại câu so sánh bằng từ so sánh nhất

	Cấu trúc
Công thức	S1 + To Be + adj-est/ the most adj + … S1 + V + the most adv + …
Viết lại câu	Nếu S1 là người: => Nobody/ No one + To be/V + as + adj/adv + as + S1 Nếu S1 là vật: =>Nothing + To be/V + as + adj/adv + as + S1
Ví dụ	Lan is the tallest of all => Nobody is as tall as Lan
