A friendship is very important for everyone, especially me. During my life, I have had many friends. Now I want to tell you about my best friend. His name is Lien Ai .He is a good, kind (and very lovely) person. He supports to me, helps me a lot when I have problems. I love him so much. But we didn't met each other, but I am sure that, if we were in the same school, we will be closer. We've had many memories, we met when we were in hoc24, we have grown to be best friend. When I was sad, he was the first one who encouraged me. When I'm in troubles, he is the most helpful. He isnot only my friend, but also my relative. He supports me in bad times and good times. And he always believes in me, I feel lucky when being his friend. I love him so much.
Badminton is one kind of exercising that will make people enjoy it. It’s also good for our health. That’s why, I’m taking badminton as one of my hobby.
Badminton is a very easy game, everyone can play it. In fact, you can play it anywhere with rackets and a shuttlecock. The shuttlecock is made from goose feathers pushed into a small piece of cork. Badminton rackets are very light. They normally weigh from 90 grams to about 110 grams. The smash of the shuttlecock can travel up to 260km per hour.
There are six main shots: the serve, the clear, the drop, the smash, the forehand drive and the backhand drive. The court on which badminton is played is in the shape of a rectangle and is divided in half by a net. There are two or four players, each team is on each side of the net.
Badminton takes its name from the home of the Duke of Beaufort, Badminton House in Gloucestershire, England where the first game of badminton was played.
There are many benefits of playing badminton for our health. It reduces bad cholesterol and increase in good cholesterol and increases the levels of HDL good cholesterol while decreasing the levels of bad cholesterols. When you play badminton, basal heart rate drops a few beats per minute and blood pressure is reduced, which protects you from heart disease. It also can reduce weight for overweigh people and attain optimal weight for their height and age. That’s why it keeps you feeling well, strong, motivated, enthusiastic and young.
I don’t like sports basically, but badminton are special. I have always been enjoying play that. I’d like to continue play this sport as my hobby and have fun.
I love to imagine.It is quite fun.I don't really like the way my school is now,so I have an idea about my dream school.My dream school will be pretty llarge.It will be just like a town.Here,students will be like sisters or brothers.They will share and help each other.My dream school will also have teachers,but they won't teach us difficult things much.Instead,they will do exercises,have fun with students.My dream school won't use notebooks or books,because ipads and computers will be used much.We can learn more and play in freetime.The playground will have:slides,swings,...like other regular schools.Just a bit odd by having dancing floor,karaoke rooms,...It sound fun,isn't it.I like my dream school,alot.

My favourite teacher is my class teacher. Her name is Nisha Gupta. She takes our attendance and teaches us Hindi, Maths and Art subject. She is well educated and taken higher studies from the Banaras Hindu University. She follows very easy and effective teaching strategies to teach us all the subjects. I never miss her class and attend daily. I the way she teaches us as we do not need to study that subject at home again. We become very clear about the topic she teaches us in the classroom. After clearing the concept of topic, she gives us some exercises in the class and also home work for the home. Next day, she asks questions related to the yesterday topic and then start another topic.
In spite of the subjects, she teaches us good ethics and etiquette also to make us strong by character. May be; she will not be our teacher in next class however; her teachings will always be with us and show us way to difficult situations. She is very caring and loving in nature. She has been the gold medalist in the university she got her higher education. She would always be my best teacher.

My Birthday Story
This story is about my last year birthday, it was very special, maybe a little thrilling. Thinking about birthday stories, you must be bored because it's about birthday, it happens everyday. But again, this one is very special. My birthday was celebrated at my house, not very crowded, just me and my family and some cousins. At first, it was a normal birthday happening as expected. After blowing the candles, making my wish. We moved on to the presents part. There was a lot of presents for me, and I started unwraping them. There was one with very thick cover so I went to my room for paper cuting knife. I was at the door of my room, but I stopped. I heard a very loud noise, it's was definitely from my room. That was NOT normal at all. My door was lock, everyone was downstair, and I was outside. So what made that noise. I might have just opened the door and checked it out, but I heard a VOICE! It was very short but I was sure that it was human sound. That was enough for me. I straighted up going down to the living room, told my dad and after just a second, he and my brother each with a pan in hand, going up to my room. They put the key into the lock and quickly opened the door. I wasn't up there so I just heard noises, I and others were just standing still, because we didn't know what to do. After about a minute, my dad shouted: "Call the police". I ran to my room and saw 2 guys wearing masks, were holding down on the floor by my dad and brother. About 15 minutes later, police came and finished everything. I was still shaking at that time cause that was crazy. I almost forgot about the presents and the birthday. So that's it. The story about my most crazy birthday (till now).
Lovely Rose
This article is about my cat. One of the most beautiful creatures god ever created. He might have made a mistake for this unacceptable perfection. She is a lady and the name is Rose. She walks with pride on her mooth legs. But do not doubt, cause she runs faster than any mouse. Her eye are black and unpredictable, just like the blackholes. Her fur is also black, blends her in with the dark at night. Her personality must be of a queen. You can pet her, if she wants you to. You can hug her, if she allows you. You do not kiss her, cause that is off limits. She might be just a cat, but her manner is of a ruler. That is all I can say about her, cause words are just letters working together to tell a story, and that is not enough to describe my lovely Rose.
