(C)
It looks like a mobile phone（手机）, but the service is much cheaper. It acts like a mobile phone, but only in your own city. Beyond the city walls, it’s useless.
“Little Smart”, also called “xiaolingtong”, has always been compared to mobile phones. But actually, it is more like one of those cordless phones(无绳电话) used around the home. The only difference is that this one reaches much further than from the bathroom to the living room. It can travel across an entire city.
Cheap costs are the main reason for the success of Little Smart. It costs 25 yuan a month for the line and about 0.1 yuan per minute to use. A mobile phone, on the other hand, can cost four or five times as much. What’s more, unlike mobile phones, there’s no fee(费) for incoming calls. So these low charges have attracted many users.
But, Little Smart is not really that smart. Users often complain about its bad voice quality. And there are not as many stations to pick up its signals（信号）as there are for mobiles. “I couldn’t receive a phone call if I was on a bus,” said Li Ping, a user in Hangzhou. “It worked fine when I stood still, but there were breaks in signal when I was moving.”
Scientists are trying to make Little Smart more user friendly. Messaging and Internet access(接入) have been added to the service. And the latest Little Smart handset even has color screen.

Australia and the United States are about the same in size, and their western lands are both not rich 5 soil. It was on the eastern coast of Australia and America that the English first settled, and both colonies soon began to develop towards the west. However, this westward 6 (move) took place 7 because the English were searching for better land than the population was increasing. Settlements of the west part of both countries developed quickly after gold 8 (discover) in America in 1849 and in Australia two years later.
Although the development of these two countries has a lot in common, there are some 9 (strike) differences as well. The United States gained its independence from England by revolution while Australia won its independence without having to go to war. Australia, 10 (like) the United States, was firstly turned into a colony by English prisoners and its economic development was in wheat growing and sheep raising. By 1922, for example, Australia had fifteen times more sheep than it had people or almost half as many sheep as there are people today in the United States. Australia and the United States have more in common with each other than either one has with most of the rest of the world. |

The world’s first plastic magnet (磁性) to work at room temperature has passed the elementary test of magnetism. Its creators at the University of Durham in the UK have used it to pick iron filings (铁屑) from a laboratory bench.
In 2001, chemists from the University of Nebraska-Lincoln claimed to have created the world’s first plastic magnet, but it only worked below 10 Kelvin (开氏温度). Other researchers have made plastic magnets, but generally they only function at extremely low temperatures, or their magnetism at room temperature is too weak to be business use.
So the Durham team can claim to have made the first plastic magnet that could be used in everyday products. One of the most likely applications is in the magnetic coating of computer hard discs, which could lead to a new generation of high-capacity discs.
Jerry Torrance, a material scientist who is an adviser to some of the world’s largest electronics and engineering companies, including IBM, describes the work as “a great scientific breakthrough”. However, he says that practical applications are probably still a long way off.
At first the new polymer (聚合物) showed little sign of magnetism, and after three months the researchers had reached the point where they felt that trying to induce (诱发) magnetism in this polymer was a waste of time. “Just as we were about to give up and try a different way, we decided to check the samples for a last time,” says Sean Giblin.
It was a fortunate decision, because over the months the original polymer had developed magnetic characteristics. Further groups of polymer proved its magnetism and ruled out the possibility that the magnetism had been caused by pollution. In addition, X-ray diffraction data (衍射数据) showed an increase in the straight line of the polymer chains over three months, which probably accounts for the increase in magnetism.
Although the polymer’s magnetism is weak compared with metal magnets, the researchers are confident that they can improve it. And in addition to computer hard discs, the team thinks that plastic magnets could have important medical applications because organic magnetic materials are less likely to be rejected by the body.

Overhead bridges are found in many parts of. Beijing, especially in places where traffic is very heavy and crossing the road is dangerous.
The purpose of these bridges is to enable pedestrians to cross roads safely. Over- head bridges are used in very much the same way as zebra crossings. They are more ef- ficient although less convenient because people have to climb up a long flight of steps. This is inconvenient especially to older people. When pedestrians use an overhead bridge, they do not hold up traffic. However, when they cross a busy road using a ze- bra crossing, traffic is held up, this is why the government has built many overhead bridges to help pedestrians and to keep traffic moving at the same time.
The government of Beijing has spent a large amount of money in building these bridges. For their own safety, pedestrians should be encouraged to use them instead of risking their lives by dashing across the road. Old people, however, may find it a little difficult to climb up and down the steps, but it is still much safer than walking across the road with all the danger of moving traffic.
Overhead bridges serve a very useful purpose. Pedestrians, both old and young, should make it a habit to use them. This will prevent unnecessary accidents and loss of life.
1. What is the advantage （优点）of overhead bridges mentioned in this passage?
A. Taller trucks can pass under them.
B. Pedestrians can climb up and have a view of the city.
C. They are safer for pedestrians and can keep traffic moving at the same fame.
D. They are easier and more convenient for the pedestrians.
2. Which of the following statements is true according to the passage?
A. Overhead bridges are found in every part of Beijing.
B.Overhead bridges are only found in center of Beijing. C.Overhead bridges are found in many parts of big cities in China. D. Overhead bridges are found in places where traffic is heavy.
3.Theunderlined words a zebra crossing probably mean _______.
A. a safe place across a road for pedestrians to walk across the road.
B. A wild animal from Africa that looks like a horse with broad dark brown and white stripes on its body
C. A safe place across a road for zebra to walk across the road
D. A safe place across a road for children to play a game.
4. What is the writer"s attitude（态度） towards overhead bridge?
A. It is inconvenient for older people to walk across the road.
B. It is much safer for pedestrians thought climbing up and down the steps may be a little difficult.
C. An overhead bridge is more beautiful than a zebra crossing.
D. To build overhead bridges is the business of the government. |

The Hawaiian Islands are situated（位于） about two thousand miles away from North America, right in the middle of the Pacific Ocean. Despite the distance the Islands actually make up the fiftieth state of the United States. The Islands were all formed by volcano（火山） eruption and on the largest of the islands, Hawai, or the Big Island, there are still two active volcanoes, the Mauna Loa and the Kilauea, which still erupt every few years.
On the Hawaiian islands the natives have a particularly strange way of indicating(指明) directions. They don"t use the north, south, east and west system common to the rest of the world. They use the mauka and makai system. Mauka means "mountain".The mountains in Hawaii are always at the center of the islands, as these are volcanic is lands. Makai means "the sea". The islands are small and the system is simple. Wherever you want to visit, it can always be described in terms of where it lies in relation to the mountains and the sea. A typical conversation(谈话) between a native Hawaiian and a visitor might go as follows.
VISITOR： Excuse me! Could you tell me where the Sheraton Hotel is? HAWAIIAN; Well ... Let me see ! From here it"s two blocks mauka,and then one
block makai. You can"t miss it!

The Romans built great "aqueducts" to carry fresh water from the mountains to the cities. Many of these aqueducts are still standing today. The Romans also built great pipes under the ground to carry away the sewage. In Rome, one of these sewage pipes (sewers) is still used today; it is 2,000 years old. The Roman Emperors even set up a government health service. They built the first great public hospitals in Europe, and they paid doctors to look after poor people.
Then the Roman Empire fell to pieces, these civilized methods of treatment disappeared from most of Europe, for more than a thousand years. People went back to the old ways. They lived in dirty conditions which helped to cause diseases（疾病）; and they asked God to cure the disease. They shut mentally sick people in prisons. Or they burnt them alive because they were supposed to have magic powers.
But the work of the Greek and Roman doctors was not lost. Over a thousand years
ago, they Arabs moved into many of the Mediterranean countries. They took big parts of the old Roman lands. They translated the Greek and Roman medical books into Arabic. Arab doctors themselves make many new discoveries.
When civilization(文明) at last came back to Europe, men once again translated the Greek and Roman works on medicine into Latin. Slowly－very slowly －European doctors discovered again the things that the Greeks and Romans had known so long ago. Slowly, they began to make new discoveries. They found out more about the way the body works--the way our blood goes round our bodies, the way our nerves（神经） send messages from our brains to our muscles, the way these muscles move our bodies.
1. The word "aqueduct" probably means _______. A. something which was built long ago
B. something invented by a Roman Emperor
C. a big pipe under the ground
D. something built to supply clean water for the citizens

3. Which of the following is NOT true?
A. A government health service was set up in ancient Rome.
B. The first public hospital in Europe was built in Rome.
C. m ancient Rome doctors were paid by the government.
D. Those who were mentally sick were all burnt alive in the Roman Empire.
