Each child should choose a subject to study, learn about that subject so that it will help himself or her in many things or needs of life.I will tell you about my favorite subject, and that is English.

With more than a quarter of the world's population using this language, someone is always speaking English.  English plays a very important role in life and work in the future, English has many uses, so it is widely used because it is an easy language to learn and has many benefits.

As a student, each of us has some favorite subjects. A favorite subject is something we can repeatedly read without getting bored. We are always on our toes to read our favorite subject. However, at school, we can see that some students perform well in all subjects. The count of such students is less. The majority of students have a favorite subject. Almost every student has a favorite subject. It does not matter if it has associated with academics or arts.

1. Describe a friend

My best friend is Lan. We have known each other since we were 10 years old. However we became best friends when we were at grade 7. At that time I was very bad at English and it was who helped me improve my English. Now she lives with her parents in Nguyen Trai street.

If I were to describe how she looks I would say she is very pretty. She has long black hair a straight nose and a small pointed chin. She is quite slim. She doesn t like to dress up so I usually see her wearing jeans and a T - shirt. She has a very nice personality and a wonderful sense of humour but she can also get a little depressed from time to time. I can always count on her to be honest and to give me the best advice.

What I like about Lan is that she has same hobbies with me. We both enjoy singing karaoke reading comic books and going shopping. We like going to the cinema but sometimes can t agree on which movie to see. In addition since I am better in Maths and Chemistry and she is better in English and languages we can always help each other if we get confused about a difficult homework assignment. We are so lucky that we get along so well. I hope that our friendship can last long.

2. Describe a room in your house

My favorite room in my house is my bedroom. My bedroom is my man cave, spa, and gym. It's my man cave because me and my cousins hang out in that room. It's my spa because I realax in that room like if it was a spa. It's a gym because thats were I have my bench, dumb bells and punching bag. Sleeping in another room is nothing like sleeping in my room. I fixed up my own room. I painted it white and dark lime green, It's pattern'd. I have a 40 inch led hdtv plasma tv. My iguana cage makes my room cooler. I wanted my room to have tile on the floor. It doesn't matter any more now that were moving from that house. Were not moving far at all, it's only like a block away.

3. Talk about your family

Our family is large (small, not very large). We are the family of five (three, four, five, six): my mother, my father, two my brother and I. My mother's name is … She is … years old. She is a farmer(a teacher a doctor, a worker, an engineer). She is a very nice, kind and clever woman. My father's name is ... He is ... years old. He is a farmer,too (a teacher, an engineer, a doctor, a businessman). He is rather tall and strong.
He is a man of strong character - and all of us love him very much. Both of my brother are machanics (students ,pupils). Their names are ... I love them very much.

We are a very good family. We love each other very much. In the evenings, when all the members of our family get together after work and study, we like to watch TV, to read books and newspapers, to talk about different things and to discuss all our problems together. When the weather is good we sometimes go for a walk. We have a small house in the country with a garden and a kitchen-garden. There is much work there and on week-ends we go there and work and have rest all together.

4. Talk about your hobbies. Why ?

Like everyone, I have my private hobbies. I have many hobbies such as watching horror films, reading novels, listening to music e.t.c But I like traveling best. Firstly, when I have to study or work too much, I usually feel tired and bored,so I want to refesh myself and travelling is a good way for me to relax.Secondly, travelling helps me widen my knowledge because I can pick up a lot of different cultures and study so much from them.Besides,I can learn foreign languages when I travel abroad. On the other hand, travelling makes my life more interesting because I can meet lots of people all over the world and make new friends.Finally, I can admire true beauty and enjoy it when I go to different places. However, it's hard for me to travel abroad because I'm always busy studying and I don't have much money.To sum up, I love travelling very much because it not only cheer me up but also keep my eyes open.

5. Talk about your village/town

I was born in a quiet village where the influence of the city is not much. It is a small village with a population of about two thousand people. It is a very good place for relaxation indeed.

In my village, people live very close to each another. The people are very simple in thought and behavior. Therefore they are friendly and helpful . So, the crimes of the city are almost unknown in my village. The people work together and live in peace. I love them. My village is surrounded by paddy-fields and a river. All these add great beauty and variety to my village scene. Although I do not like growing rice, but I really like the fields. It makes me have a good mood, a peace mood and a relaxed mood.

Now I am living in Hanoi capital. I want to come back my hometown very much. Living among such friendly and simple people, in such a quiet village, is indeed a real pleasure.

27^150=(3^3)^150=3^450 còn 9^=(3^3)^226=3^678. Vậy 9^226>27^150

Mai Anh tính sai rồi nha bạn dù kết quả của bạn vẫn đúng nha

27^150 = (3^3)^150 = 3^450

9^226= (3^2)^226 = 3^452 

Mà 3^452 > 3^450 suy ra  9^226 > 27^150
