As you may expect, life in space is much different from life on earth. So of course people need some time to get used to it. How do they live, work and play up there?
Space food keeps getting more like the food we eat at home on the earth. In the past, astronauts could eat only freeze-dried food. But now the space station has water, microwave ovens and fridges. So astronauts can eat more usual kinds of food, like fruit, vegetables and ice cream!
All people in the ISS（国际空间站）have their own rooms. There’s no gravity, so they have to attach themselves to their beds, or they’ll float away! That may seem like a hard way to sleep, but astronauts say that sleeping in space is actually not too bad.
This is more important in space than on Earth. There’s not much gravity in space. Astronauts don’t stand up, sit down or walk in space, so their muscles don’t have to work much. They exercise on bikes and other machines for about two hours every day while they’re in space. In this way, they can still keep strong and healthy when they get back home.
Easy things like brushing your teeth can be hard in space with low gravity. Water doesn’t flow out of a tap, it floats in a bubble（水泡）! Astronauts used a special hose（软管）to take showers. And when they’re finished, they use a vacuum（真空的）hose to suck the dirty water off of their bodies. How do you go to the toilet in space? They use a special “air toilet”. It uses air, not water, to take everything away.
What do astronauts do when they aren’t working? They read books, play cards, listen to music or send e-mail to their friends and family. Sometimes they just sit and look out the window. Doesn’t sound like much fun? But what if you could see planet Earth out of your window, with a sunset or sunrise every 45 minutes?
1． Which of the following can be the title of this passage?
A. Life In Space. B. Space Food. C. Showers In Space. D. A Visit To Space

A. astronauts eat quite different food in space from what they eat on the earth
B. astronauts ate only fruit in space in the past

3．Astronauts attach themselves to bed so as to ________.
A. keep themselves warm B. prevent themselves from floating away
C. have a good sleep D. feel better
4．Astronauts have to do exercise for two hours every day because ________.
A. they have nothing to do in space B. they are told to do so
C. they do so to keep healthy D. they do so to prevent them from sleeping
5．From the last paragraph we can guess that ________.
A. the sun moves fast around the earth
B. the earth circles round the sun very fast
C. the earth is very small
D. the spaceship circles round the earth once every 90 imnutes

Imagine you’re at a party full of strangers.You’re nervous.Who are these people?How do you start a conversation?Fortunately,you’ve got a thing that sends out energy at tiny chips in everyone’s name tag(标签).The chips send back name,job,hobbies,and the time available for meeting—whatever.Making new friends becomes simple.
This hasn’t quite happened in real life.But the world is already experiencing a revolution using RFID technology.
An RFID tag with a tiny chip can be fixed in a product,under your pet’s skin,even under your own skin.Passive RFID tags have no energy source—batteries because they do not need it.The energy comes from the reader,a scanning device(装置),that sends out energy(for example,radio waves) that starts up the tag immediately.
Such a tag carries information specific to that object,and the data can be updated.Already,RFID technology is used for recongnizing each car or truck on the road and it might appear in your passport.Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records.At a nightclub in Paris or in New York the same chip gets you into the VIP(very important person) section and pays for the bill with the wave of an arm.
Take a step back:10 or 12 years ago,you would have heard about the coming age of computing.One example always seemed to surface:Your refrigerator would know when you needed to buy more milk.The concept was that computer chips could be put everywhere and send information in a smart network that would make ordinary life simpler.
RFID tags are a small part of this phenomenon.“The world is going to be a loosely coupled set of individual small devices,connected wirelessly,”predicts Dr.J.Reich.Human right supporters are nervous about the possibilities of such technology.It goes too far tracking school kids through RFID tags,they say.We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it.And how many beers.Accompanied by how many biscuits.
When Marconi invented radio,he thought it would be used for ship-to-shore communication,not for pop music.Who knows how RFID and related technologies will be used in the future.Here’s a wild guess:Not for buying milk.
1.The article is intended to ______.
A.warn people of the possible risks in adopting RFID technology
B.explain the benefits brought about by RFID technology
C.convince people of the uses of RFID technology
D.predict the applications of RFID technology
2.We know from the passage that with the help of RFID tags,people ______.
A.will have no trouble getting data about others
B.will have more energy for conversation
C.will have more time to make friends
D.won’t feel shy at parties any longer
3.Passive RFID tags chiefly consist of ______.
A.scanning devices
B.radio waves
C.batteries
D.chips
4.Why are some people worried about RFID technology?
A.Because children will be tracked by strangers.
B.Because market competition will become more fierce.
C.Because their private lives will be greatly affected.
D.Because customers will be forced to buy more products.
5.The last paragraph implies that RFID technology ______.
A.will not be used for such matters as buying milk
B.will be widely used,including for buying milk
C.will be limited to communication uses
D.will probably be used for pop music
