I study in ...............(viết tên trường) Secondary School. It is one of the best schools in Singapore. It consists of several Roman style buildings. Our school has all the facilities of a modern school, such as well furnished and airy class rooms, best laboratories, a big library with a huge collection of books, a vast play ground and even a swimming pool.

Our school building is situated in the middle. There is motorway leading from the main entrance. The playground is on the left of the motorway and a big garden on the right. When you enter the building, the principal’s room is on the left. They are all well furnished. There are twenty classrooms. Our laboratories are well equipped. The school library has an up-to-date collection of books on many subjects. Our librarian and her two assistants are very helpful.


Our school, like other schools, has prescribed a uniform for us. We have to wear white trousers, a white shirt and a black tie. The girls have to wear white shirts and skirts.

Our principal is very strict as he pays strict attention to behavior, punctuality and cleanliness. The most well-behaved and punctual student will be assigned as the class prefect.

Our principal is a strict disciplinarian. He accepts the help and advice of all teachers. Though our principal is strict, he is fair and loving. He tries to find out the reason and guides us. If one violates any rules, he will be punished. Our principal is very strict in this aspect.

Our teachers are also very strict. They teach us with the utmost care, guide us with our assessments and other preparations and help us in times of need.

I like my school very much and am proud to be a student of that school.
