Mức độ so sánh của trạng từ và tính từ

Part A: theory
Degree of comparison of adjectives and adverbs
I. so sánh ngang bằng ( Equal comparison)
1. S + “be” + as + adj + as + N ( đại từ )
Ex:

-He is as tall as his father.
-Mai is as beautiful as her friend.
2. S + V + as + adv + as + N ( đại từ )

Ex: - John sings as well as his sister.
Notes: * Có thể dùng “So” thay cho “as” trong những câu phủ định.
Ex: - His job is not so difficult as mine.
• Ý “bằng nhau, như nhau” có thể được diễn đạt cách khác:
S+ V + the same + (N) + as + N (pronoun).
Ex. - My house is as high as his.
→ My house is the same height as his.
- Tom is as old as Mary.
→ Tom and Mary are the same age.
* Chúng ta dùng “ the same as” chứ không dùng “ the same like”
Chú ý các tính từ sau và các danh từ tương ứng của chúng.

II. So sánh hơn. ( Comparatives)
1. So sánh hơn ( Comparatives)
- Adj ngắn 1 âm tiết + er: Ex. Thick → thicker, colder → colder….
+ Với những tính từ 1 âm tiết có câu tạo: phụ âm + nguyên âm + phụ âm thì ta gấp
đơi phụ âm cuối rồi thêm er:
Ex. Hot → hotter, big → bigger
- Với những tính từ 2âm tiết có tân cùng là đi: –y, -er, -ow ,-le: thì ta them đi er:
Ex. dirty, simple, clever, narrow → Dirtier, simpler, cleverer, narrower
+ Cịn lại những tính từ 2 âm tiết khác ta thêm more đằng trước tính từ.
