Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．

Everywhere you look, large quantities of information in the world are pouring. This data flood is already starting to transform business, government, science and everyday life. It has great potential for good — as long as consumers, companies and governments make the right choices about when to restrict the flow of data, and when to encourage it.
A few industries have led the way in their ability to gather and take advantage of the data. Credit-card companies monitor every purchase and can identify cheats with a high degree of accuracy. Stolen credit cards are more likely to be used to buy hard liquor than wine, for example, because it is easier to overlook. Insurance firms are also good at combining clues to spot doubtful claims: dishonest claims are more likely to be made on a Monday than a Tuesday, since policyholders (保险客户) who stage accidents tend to assemble friends as false witnesses over the weekend. By combining many such rules, it is possible to work out which cards are likeliest to have been stolen, and which claims are untrue. By analyzing “basket data”, supermarkets can make promotions to appeal to particular customers’ preferences. The oil industry uses supercomputers to help them before drilling wells.
But the data flood also poses risks. There are many examples of databases being stolen: disks full of social-security data go missing, laptops loaded with tax records are left in taxis, credit-card numbers are stolen by online purchase. The result can be privacy made public, identity stolen and cheats permitted large space. Rather than owning and controlling their own personal data, they very often find that they have lost control of it.
The best way to deal with the data flood is to make more data available in the right way, by requiring greater transparency in several areas. First, users should be given greater access to and control over the information held about them, including whom it is shared with. Google allows users to see what information it holds about them, and lets them delete their search histories or modify the targeting of advertising, for example. Second, organizations should be required to disclose details of security breaches (安全漏洞), as is already the case in some parts of the world, to encourage bosses to take information security more seriously. Third, organizations should be subject to an annual security check, with the resulting grade made public (though details of any problems exposed would not be). This would encourage companies to keep their security measures up to date.
1.What is the best title for this passage?
A. Information Flood B. Benefits of Data Flood
C. Harms of Data Flood D. How to Use Data in a Right Way
2.From the passage we can infer that _____.
A. lots of data are lost because of hardware problems
B. online purchases are becoming more and more popular
C. credit cards are not so secure to use and will go out of use very soon
D. insurance firms have to investigate before they confirm their policyholders’ claims
3.Which of the following is the writer’s opinion about how to deal with the data flood?
A. Personal information should be used for public benefits.
B. The users should be given the right to access public information.
C. Companies should update their measures to guarantee their data safety.
D. Organizations should keep their resulting grade of security checks unknown to the public.
4.From the passage we can conclude that _____.
A. the data flood makes peoples’ life less convenient and more expensive
B. companies and insurance firms are responsible for the data flood
C. the information flood is more useful to organizations than to individuals
D. the information flood has both positive and negative influence on modern life

We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of junk. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get tangled (缠绕在一起的). Thankfully, something has come along to help rid our homes of this mess while still supplying these devices with the power they need. It’s called wireless charging and this trend is just starting.
Wireless charging has a lot of potential for smartphones and other electronic devices. Electronic devices can absorb the electricity once they’re placed on a special charging mat. There are several advantages that wireless charging offers over traditional methods. For starters, cords (电线) have a tendency to wear out with use. Wireless charging users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won’t need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging gets rid of that danger completely.
Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be gotten rid of in the future, as researchers are developing transmitters (发射器) that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.
1.What is a problem with many modern appliances?
A. Most people can’t afford to pay for them.

D. They are not very entertaining.
2.Why is wireless charging beneficial for medical patients?
A. It often brings down the cost for their medical bills.
B. Wireless charging has shown to cure people of serious diseases.
C. It is more convenient to check or repair their devices.
D. It’s being used as a replacement for many pills.
3.Which of the following is a disadvantage of wireless charging?

B. People can now buy fewer devices for their homes.
C. It takes longer to charge your battery wirelessly.
D. People can’t plug in their devices conveniently.
4.What seem to be the author’s attitude towards wireless charging?

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland（瑞士）and China, built by the government（政府）to help some of the people live during a great war.
But will people change if they live under the ground for a long time？For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals（化学制剂）in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone？
1.People will live under the ground because _________．
A．it’s neither hot nor cold there
B．they’ll be afraid of the war
C．there’ll be less space on the ground
D．they’ll make their life comfortable
2.Some countries try to build some places under the ground so that people will be able to live there _____．
A．when summer comes
B．when a war breaks out
C．because they think it’ll be safer for them
D．when they’re fed up with the life on the land
3._________, so people who will live there won’t go blind．
A．There’ll be enough light under the ground
B．It’ll be easy to go upstairs
C．Glasses will be sold under the ground
D．Medicine will be supplied for free
4.People will lose some senses under the ground because _______．
A．the world are polluted
B．it’s dark there
C．the air is dirty and there are a lot of chemicals in their food
