S + [BE]* + Adj.
Eg: This room is large. His face is round. I am tall. Lan is very good. ...............

S + [BE/HAVE]* + (a/an)* + Adj + N. = S + [BE]* + Adj.

C- NỘI DUNG 3- ENOUGH TO: [= đủ.để (làm gì]
I- Khái niệm- Cách dùng: 
* Dùng để diễn tả điều kiện đủ/(không đủ)để (làm gì đó).
 	 * Theo sau ENOUGH luôn là một động từ nguyên mẫu có “to” [TO-infinitive].
II- Cấu tạo chung:
S + [be/ V]* + [Adj/Adv]* + ENOUGH + (for + O)* + TO-infinitive.
* Lưu ý:
1- Trường hợp Chủ ngữ [S] ở hai mệnh đề cùng một đối tượng => Không cần có [FOR + O]*. 
Eg: 1- Nga is not old. She is not in my class.
	 => Nga is not old enough to be in my class.
 2- My father runs very quickly. He can catch that bus.
 => My father runs quickly enough to catch that bus.
2- Trường hợp Chủ ngữ [S] ở hai mệnh đề là 2 đối tượng khác nhau => Ta chuyển Chủ ngữ [S] ở mệnh đế sau thành [FOR + O]* và đặt sau ENGOUGH.
Eg: 1- That ceiling is short. I can reach the ceiling.
 => That ceiling is short enough for me to reach.
 2- Those questions are very easy. We can answer them.
 => Those questions are easy enough for us to answer .
 3- He speaks slowly. Lan can understand him
 => He speaks slowly enough for Lan to understand.
3- Trường hợp dùng Tính từ [Adj]* hay Trạng từ [Adv]* phụ thuộc động từ trước đó là [BE]* hay [V]*. => Xem III..
III- Các cấu trúc cụ thể:
1- Nếu động từ đứng trước là [BE]* => Theo sau là một Tính từ [Adj]:
S + [BE]* + Adj + ENOUGH + (for + O)* + TO-infinitive.
* Lưu ý: [BE]* có thể được chia ở nhiều thì khác nhau.
- Phủ định, ta thêm [NOT] sau [BE] (hoặc sau Trợ động từ- nếu có).
- Câu hỏi, ta đặt [BE] (hoặc Trợ động từ- nếu có) lên trước Chủ ngữ [S].
* Ví dụ: 
1- I am (not) tall enough to reach that ceiling.
2- They are (not) intelligent enough to answer those questions.
3- When she was a little girl, she was (not) clever enough to do such nice things. 
4- I think I will (won’t) be clever enough to be a doctor in the future.
5- Are you/ Were you fine enough to continue that work?
6- Will you be free enough to join the activities tomorrow ?
2- Ta có thể thay [BE]* bằng các động từ nối [FEEL/SEEM/APPEAR/LOOK/GET/ SOUND/]* => Theo sau cũng là một Tính từ [Adj]:
S + [feel/seem/look/..]* + Adj + ENOUGH + (for + O)* + TO-infi...
* Ví dụ: 
1- She looks strong enough to knock him out. 
2- The weather seems fine enough for us to go out tonight.
* Ở Phủ định và Câu hỏi, ta phải áp dụng qui tắc của động từ thường:
3- Those questions don’t / didn’t seem easy enough for us to answer .
4- Do/Did/Will you feel fine enough to continue that work?
3- Nếu động từ đứng trước là Động từ thường [V]* => Theo sau là một Trạng từ [Adv]:
S + [V]* + Adv + ENOUGH + (for + O)* + TO-infinitive.
	* Lưu ý: Động từ thường [V]* có thể được chia ở nhiều thì khác nhau. Ở Phủ định và Câu hỏi, ta áp dụng qui tắc của động từ thường.
* Ví dụ: 
1, He dances beautifully enough to attract that beautiful girl.
2, He can (not) run quickly enough to catch that train.
3, Nga doesn’t/didn’t do her tests well enough to get good grades.
4, Does/ Did/Will/Can you work hard enough to earm much money?.
4- Ta có thể dùng Danh từ [N] theo sau ENOUGH.
S + [be/V]* + ENOUGH + N + (for + O)* + TO-infinitive.
* Ví dụ: 
1, There is (not) enough milk for us to drink.
2, I have enough money to buy a new house.
3, Nga doesn’t/didn’t prepare enough food to eat.
	IV. BÀI TẬP.
I. Nối kết các cặp câu sau, sử dụng “ENOUGH TO”. (nghĩa không đỗi).
Ex: 1, Mysister is old. She can drive a car. 
 => Mysister is old enough to drive a car. 
 2, The weather isn’t very cold. We can go swimming
 => The weather is warm enough for us to go swimming.
* Một số hướng dẫn làm bài cần ghi nhớ: 
Khi làm bài tập kết nối một cặp câu đơn (mệnh đề) dùng “ENOUGH TO”, ta cần lưu ý:
(1)- Nghĩa câu sẽ không đổi so với câu đã cho. Muốn làm được như vậy ta cần ghi nhớ:
- Nếu động từ ở 2 mệnh đề cùng thể (cùng khẳng định hoặc cùng phủ định) => giữ nguyên thể và Tính từ/Trạng từ đã cho.
* Eg: - Nga is short. She cannot reach the ceiling.
 => Nga is not tall enough to reach the ceiling.
 - The weather is not very* cold. We can go swimming
 => The weather is warm enough for us* to go swimming.
 - Lan came late. She couldn’t catch the train.
 => Lan didn’t come early enough to catch the train.
- Nếu động từ ở 2 mệnh đề trái thể (khẳng định - phủ định hoặc phủ định - khẳng định) => phải đổi thể cho động từ ở mệnh đề trước (khẳng định => phủ định và ngược lại), đồng thời đổi Tính từ/Trạng từ đã cho ở mệnh đề trước sang dạng trái nghĩa. 
* Eg: - Nam is strong. He can move this table away.
 => Nam is strong enough to move this table away.
 - Hoa didn’t study hard, so she couldn’t get good grades.
 => Hoa didn’t study hard enough to get good grades.
(2)- Sẽ không còn các trạng từ chỉ cấp độ [so/ too/ extremely/ very/ quite] trước [Adj/Adv + ENOUGH TO ] (=> Bỏ các trạng từ chỉ cấp độ [so/ too/ extremely/ very/ quite] trước Tính từ [Adj] hoặc Trạng từ [Adv] ở mệnh đề trước).
* Eg: - Tom was so* intelligent. He answered all those questions excellently.
 => Tom was intelligent enough to answer all those questions excellently.
 - Nga is extremely* humorous. She often makes others laugh happily. 
 => Nga is humorous enough to make others laugh happily. 
(3)- Nếu Chủ ngữ [S] ở 2 mệnh đề cùng một đối tượng, ta lược bỏ Chủ ngữ [S] và Trợ động từ (nếu có) ở mệnh đề 2, đồng thời chuyển Động từ chính [V]* ở mệnh đề 2 về dạng [TO-infinitive] đặt sau ENOUGH (=> Không cần có [for + O]*).
* Eg: - Mr. Robinson isn’t rich. He can’t buy a new house.
 => Mr. Robinson isn’t rich enough to buy a new house.
 - Nam was so* kind. He took me home yesterday.
 => Nam was kind enough to take me home yesterday.
(4)- Nếu Chủ ngữ [S] ở 2 mệnh đề là 2 đối tượng khác nhau, ta chuyển Chủ ngữ [S] ở mệnh đề 2 thành [for + O]* và đặt sau ENOUGH, bỏ Trợ động từ (nếu có), đồng thời chuyển Động từ chính [V]* ở mệnh đề 2 về dạng [TO-infinitive] đặt sau [for + O]*. 
* Eg: - It’s not warm. You shouldn’t wear this coat in winter. 
 => It’s not warm enough for you to wear this coat in winter. .
 - The weather was good yesterday, so we went out for a picnic.
=> Yesterday, the weather was good enough for us to go out for a picnic.
(5)- Nếu Chủ ngữ [S] ở mệnh đề trước và Tân ngữ [O] của động từ ở mệnh đề sau cùng một đối tượng giống nhau, ta sẽ bỏ (không lặp lại) Tân ngữ [O] đó sau [ENOUGH + TO-infinitive]. 
* Eg: - The shoes aren’t big. We cannot wear them*.
 => The shoes aren’t big enough for us to wear.
 - The radio isn’t small . You can’t put it* in your pocket.

A- TOO..TO [= quá..để (làm gì)].
I. So sánh TOO..TO và ENOUGH TO
TOO..TO [= quá..để (làm gì)]
=> không thể làm được.
ENOUGH TO [= đủ..để (làm gì)] 
=> có thể làm được.
* Eg:
1- He is very poor. He cannot buy a small house.
=> He is too poor to buy a small house.
2- I am not tall. I can’t reach that ceiling
=> I am too short to reach that ceiling.
* Eg:
1- He is very rich. He can buy a big house.
=> He is rich enough to buy a big house.
2- I am tall. I can reach that ceiling.
=> I am tall enough to reach that ceiling.
* Khái niệm- Cách dùng: 
- Dùng để diễn tả điều kiện quáđể (làm gì đó) =>
