1 . Did you hear of the supercomputer? Recently, China’s Tianhe-1(天河一号) was ranked as the world’s fastest supercomputer, according to a new list of world’s TOP 500 supercomputers.
It took 200 Chinese scientists two years to build the fastest supercomputer. It can do 2, 507 trillion (万亿次) calculations (计算) in a second! That means it will take a personal computer 600 years to finish the work that a supercomputer does in a day!
The US now leads the world in the area of supercomputers. It is home to more than half of the world’s top 500 supercomputers. Japan also has advanced technology. China is developing its supercomputer technology quickly. But experts say it will take years before China’s total computing power can catch up with that of the US.
Supercomputers can work on many different things. They can solve problems in areas like national defense(国防), energy and science. In business, you can also use supercomputers. Oil companies use them to find oil and gas. Banks use them for quick trades. Food companies even use supercomputers to make sure that they put potato chips into cans without breaking them.
To make a supercomputer, scientists first need to link (连接) thousands of small computers together. Then they use software(软件) to turn them into one supercomputer. In fact, any person with enough knowledge about computers can make a supercomputer. But you need the top technology to make a supercomputer run fast.

How are you? It has been a month since my family left Hong Kong for England and we are fine.
England is very different from Hong Kong. The weather is terrible and it rains a lot. The buildings are funny. They are in rows and not high. I love them because the rooms are much larger. I’m having a wonderful at my new school and my new home!
Mum and Dad are happy with their new jobs. But my brother Jack doesn’t like moving to England because he misses his friends so much.
I’ve made lots of new friends at school. My teachers are really nice too and my English has improved a lot. After school, we can take part in relaxing activities such as sport, watching films or playing computer games. There’s a park near the school where I often go with the other students at the weekend.
We are travelling back to Hong Kong for the summer holiday. I will visit you and bring you a present!
Write back soon!
Love
Sandy
