阅读理解(二)(本题共5小题;每小题2分,满分10分)

阅读下列短文回答问题:

  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. 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 favorite 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 the Human and Nature room. You can compare your speed with animals there. You hear a noise and push a button. If you aren’t fast enough, the lion catches you! I’m faster than all my friends, but the lion still catches me.

  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 favorite museum in the whole world.

1.Where does Tony go first when he visits the Science Museum?

2.What can you try out in the Human and Nature room?

3.How much does it cost to go in the Science Museum?

4.How long can you stay at the Science Museum ?

What is your favorite colour? Do you like yellow, orange, red? If you do, you must be an optimist (乐观者), a leader or an active person who enjoys life, people and excitement. Do you prefer grey and blue? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined(有决心的). You wish to succeed and want other people to see you are successful. At least this is what psychologists(心理学家)tell us, and they should know, because they have been seriously studying the meaning of colour preference (爱好), and the effect that colours have on human beings(人类).They tell us that we don't choose our favorite colour as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

A yellow room makes us feel more cheerful and comfortable than a dark green one, and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing(压抑的). Light and bright colours make people not only happier but also more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark grey .

Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colourful things. Remember also that you will know your friends and your enemies better when you find out what colours they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief or a lampshade(灯罩).

Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars (星球大战) . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made “brain”. Leading the robot revolution (革命)are industrial(企业) robots that work in factories. Industrial(工业) robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you saw in  Star Wars. But, their makers say, today’s home robots “walk”, sense objects(感知物体) in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect.
We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths(波长) of light, and hear certain sounds. That’s because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can’t. To understand what their sensing devices(传感器) pick up is a hard job. Remember, man—made brains handle(处理)information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like—using only zeroes and ones.
