     It didn’t take long at all for me to decide to come and study in the UK. With the approach of

globalization, more and more people realize that it is necessary to study in an English-speaking country.

UK does not only offer the chance to study the original English, it also has so many first-class universities, whose qualifications are widely respected all over the world. Besides the academic, there are many fun

elements too; its famous football environment is definitely one for me! Since UK has such a diverse society, I feel there is less chance that there would be any racism(种族歧视) at boarding school. This is one

reason why I did not take any summer courses before I started my school. It was just so easy to settle in

and pick up the language as you go along, because everyone is so friendly and helpful. At the moment I am doing 5 A-levels and 1 AS, which are Maths, Further Maths, Physics, Chemistry, Government and Politics and Chinese. I am aiming to achieve A’s in all my exams, and I hope to go to Oxford University to study

Engineering Science in the autumn.

     I still remember my first day at Merchiston Castle School, and I was really nervous about it, because I have never visited the school before and didn’t take any summer courses. Despite my anxiety, I soon

relaxed once I arrived; the staff members were so nice that I felt that my spoken English was better than it actually was! As soon as I walked into the day room (日间休息室) of my boarding house, I was

absolutely amazed by the friendly atmosphere: Everyone was so friendly that a boy as shy as I had no

difficulty in setting in, and I made many new friends on my very first day, although I was struggling to

remember all the names.
