Tuổi con chiếm 1 phần thì tuổi mẹ chiếm 5 phần

Khi tuổi mẹ gấp 8 lần tuổi con thì:

Tuổi con là :

28 : (5 - 1) = 7(tuổi)

Tuổi mẹ là:

7 x 5 = 35(tuổi)

2.Cách đây 3 năm em 5 tuổi thi:

Tuổi em hiện tại là:

3 + 5 = 8 (tuổi)

Vì em kém anh 6 tuổi nên mà hiệu số tuổi không thay đổi qua mỗi năm

Tuổi anh hiện nay là:

8 + 6 = 14(tuổi)

Tuổi anh khi gấp 3 lần tuổi em chiếm 3 phần thì tuổi em chiếm 1 phần

Tuổi em khi đó:

6 : (3 - 1) = 3(tuổi)

Vậy cách đây:

8 - 3 = 5(năm) tuổi anh gấp 3 lần tuổi em

The book which is the most meaningful to me is "Uncle Tom's cabin". It was about a black man, whose name was Tom, and his life. Tom was a kind and hard-working slave. His first master was Mr. Shelby. Mr. Shelby was a very kind master. Johnny, who was Mr.Shelby's son, loved uncle Tom very much. The Shelby family was very good and rich, then Mr. Shelby lost his job so he had to sell Tom because he didn't have enough money. Poor uncle Tom traveled deeper South with a terrible master. There he met a little girl, whose name was Eva. Eva d uncle Tom very much, so she bought him. But Eva was so weak, she couldn't live any longer. Her father promised her that he would free Tom after she died. But Eva's father died before signing Tom's freedom paper. So he was sold to a mean farmer, Simon Legree. Legree took Tom deeper to the South. Tom feared that he would never see his family again. Legree beat him very badly. Oneday, Johnny came to Legree's farm to buy Tom but Tom was very weak, then Johnny was sad because Tom died . His family was very sad, too. This story was so moving, it made me moved into tears. Poor uncle Tom couldn't see his family one last time before he died. This story shows us how awful race discrimination is. I do hope that the world will be peacefull, and there will be no more racism

       One weekend, my parents decided to bring my brother and I to the recreational jungle. We were very excited as we had not been there before. My brother and I talked about all the bears, tigers and reindeer we were going to see. We really thought that a recreational jungle was any other jungle.

       When we arrived, we dashed into the jungle, wanting to explore its length and breadth. We obediently followed our parents at first but found it boring. Just then, a rabbit rushed out. I screamed in delight and ran after it. My brother followed quickly behind. We kept running, always keeping our eyes on the rabbit. The rabbit got tired of running and decided to hide in its burrow.

       It was only then that we realized that we did not know where we were. The trees looked unfamiliar and there were no more jungle paths for us to follow. We were scared as we realized that we were lost. Night was approaching and the hooting of the owl sent shivers down our spines. I began to cry as I was feeling tired, hungry and sleepy. My brother comforted me by letting me sleep on his lap. I soon fell asleep dreaming of bears waiting to eat me up.

       Suddenly, I woke up. My brother was shaking me and telling them to get up. We could hear voices coming our way ! We shouted with all our might that we were lost. We soon saw beams of light from countless torches. Then we heard our parents' voices. We were safe! My brother and I ran to our parents and embraced them emotionally. We were so happy to see them again that we vowed we never wanted to be separated from them ever again.

Kể theo ngôi thứ nhất

Kể theo ngôi này người kể xưng ( tôi ). Đây là vị trí của người kể cho phép kể những gì mình biết, mình thấy, mình chịu trách nhiệm một cách công khai.

Nhược điểm

Hạn chế tầm nhìn và hiểu biết của một người.

Kể theo nhôi kể thứ ba

Kể theo nhôi này người kể dấu mình không xưng ( tôi ) chỉ kín đáo gọi sự vật theo ngôi thứ ba: nó, chúng nó hoặc tên nhân vật, sự vật theo nhận xét của mình và kể sao cho sụe việc tự nó diển ra.

Nhược điểm

Khó bày tỏ cảm xúc.
