第二节书面表达（满分25分）
Possible version
A: I Believe I Can Fly
I Believe I Can Fly is a nice song. This song tells us that confidence is very important. When we have
confidence, we believe that we can succeed. Not only can it make us face difficulty bravely, but it can also
encourage us to be successful. It’s necessary for us to have dreams and confidence. If we believe we can fly, then
we can really fly some day.
I think I’ll never give up whenever I meet any difficulty. I believe in myself and I’m sure to achieve
Success in the future.
B: The Unique Schoolyard (Campus)
On stepping into this school, I found myself falling in love with it. My first impression of it was “unique”,
for it’s filled with love and beauty. The campus consists of 2 pools, a large playground, a gym and a host of
buildings which we study in. Also there are quite a few trees and beautiful flowers which are fascinating in
spring. In addition, I am fond of the scenery as it gives me a sense of life.
I have to say that it’s just like a big family, mainly because people here are extremely friendly and easy-going. Here, we regard teachers as good friends, and they also regard us as friends. It’s no wonder that we lead a
happy life!
Actually, it’s quite easy to find a person to communicate or discuss with here. The fact is that most of us
have our own valuable thoughts on certain questions. As George Bernard said, “If you have an apple and I have
an apple, and we exchange apples, we both still only have one apple. But if you have an idea and I have an idea,
and we exchange ideas, we each now have two ideas.”
Are you interested in our school? If so, why not come and see it!
