In my house , I have a my room . It is the best room for me . I love it very much .I can store a lot of my important things in it. I will clean the room from time to time. There was a small bed in my room, which was just enough for me to sleep alone. There's also a small cupboard in the room to put up my clothes. Next to the bed where I slept, there was a white carpet under the small round table. That table was where I used to play chibi dolls. Ah, forgot the bookshelf on the headboard. The bookshelf is neatly lined with thick novels.Seeing me keep the room clean, my parents are very pleased.they kept complimenting me.I find it essential to keep the rooms in order.I love my room and I want the other rooms to be that.

I live in a big city, and my house is not very big since there are only rich people who can afford to live in a spacious house. Every room in my house is just enough for our activities, so we do not have much space for the living room. However, we try our best to decorate it because it is where the whole family gathers after a long day staying outside. We lay down a thick rug on the floor, it both helps to decorate and keep the floor safe from the scratches. To save some space, we put the TV and the loud speakers on the wall. The Play Station, DVD player and other electronic devices are put in a small cabinet in the corner of the room, and we only take them out whenever we want to play something. In the middle of the room is a glass table, we put on the surface a bottle of fresh water and some cups so everyone can have a quick drink before leaving or after coming back to the house. Behind the table is a big white couch, and it can be considered as the biggest thing in the living room. My mother loves the pastel tone, so the walls are painted in cream color; and they all go very well with the couch. We do not have any window there, so we install an air conditioner to keep the atmosphere cool. We hang some pictures of landscape as well as painting on the walls to make the room livelier. There are also a pot of a small plant in the corner of the room, so we can get some fresh air from it. Every night, we would gather to watch TV or sing karaoke, and it is my favorite time of the day. Although the living room is no too big, our family will always have good times there together.

STUDY WELL

Today, most children can go to school, so they all have to fulfill their responsibility to study well. 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. English is the most widely used language. Depending on how you calculate it, besides nearly 400 million native speakers, English is understood and / or spoken by 1-1.6 million people worldwide. 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. Sometimes we learn English because of personal interests . English for education, for tourism, for careers . I learn English 2 hours a day. During that time, I researched knowledge online, did English exercises, and communicated with foreigners through English learning software. I study English 6 days a week because I love English. My dream is become to a translater . it will take a lot of time for learning and learning to fulfill this dream ucows. I will always try and persevere. I believe if I have a will, my dream will come true !

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.
