1. Sở thích

I very like outdoor activities so Swimming is my hobby. I took up my hobby when I was ten years old. I think my hobby is difficult because It's very difficult to learn. I think my hobby is usefull because It's help me keep fit. I usually go swimming with my friends at the pool near my house. Equipments I need are: gogles, a life jacket, swimming clothes, swimming hat... I feel very happy and exciting because I can play in the water and keep fit at the same time. I will continue my hobby in the future because It's help me keep fit and relax for a hard working day.

2. Ngôi nhà mơ ước

In the future, I will live in amazing house. It's in the city. It's surrounds by a swimming pool in front and a large flower garden behind the dream house. The house will have twenty rooms. It's will have a wind energy to make electricity and a wireless TV, a smart robot, an automatic dishwasher, an automatic washing machine, solar energy, a super car and hi- tech fridge...A robot to cook dinner, wash clothes, look after children and to feed cats and dogs. A wireless TV can surf the Internet, send and receive e- mails and order food from the markets without getting out of bed.

( P/S: hihi bài về sở thích thì mình vừa mới nghĩ ra làm không biết có đúng hay không nữa, có gì thì bạn tham khảo thôi nhé. Còn về bài ngôi nhà mơ ước thì bài đó mình học hồi năm lớp 6 nên giờ cũng hơi quên, nhớ nhiêu làm nhiêu thôi à nên bạn thông cảm nhé ^^)
