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 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 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.
The world’s fastest supercomputer ________.

A．was made in America

B．was made within two months

C．can do 2,507 trillion calculations in a minute

D．was made by 200 Chinese scientists

Among the world’s top 500 supercomputers, ________ of them are made in the US.

A．less than 20%	B．more than 50%

A．supercomputers can be used in different kinds of areas

B．supercomputers can work fast

C．supercomputers can only be used to find oil and gas

D．supercomputers can be used to make money

According to the passage, to make a supercomputer, ________.

A．you needn’t know enough knowledge about computers

B．you need to know how to play computer games

C．scientists first need to link thousands of small computers together

The most unusual museum in London is the Science Museum. In most museums, there’s no shouting and no running, and you aren’t allowed to touch the exhibits(展品). But the Science Museum is different, because it’s noisy! People talk about what they can see and do there, and some of the machines are noisy as well. Visiting the Science Museum is fun and it’s a great way to learn about science because you can work things out and try out ideas.
When I visit the Science Museum, I go to the Launch Pad. This is my favourite room because you can do physics experiments. For example, if you want to fill a bag with falling sand, you have to move a kind of truck on wheels into the correct position. I also go to the Rocket Show. You can learn how we travel into space and back again.
Then I go upstairs to Human and Nature room. You can compare your speed with animals there. You hear a noise and push a button(按钮). If you aren’t fast enough, the lion catches you! I’m faster than all my friends, but the lion still catches me.
There are also rooms on transport, the environment and space technology, as well as maths, physics and chemistry.
You can do a lot of things in this museum, but you have to obey some rules as well. For example, you mustn’t take photos of the exhibits in the museum. But you can buy postcards of them in the museum shops.
Above all, the Science Museum is free. That means you can drop in for a few minutes or you can stay as long as you like—it’s open every day, from 10 am to 6 pm. So if you ever go to London, make sure you visit the Science Museum. It’s my favourite museum in the whole world.
