The Great Wall of China is one of Beijing’s biggest draws for tourists; despite its fame and ubiquity in postcards across the world, it rarely fails to attract tourists at the first proper sight.Yet the authorities open only certain sections of the wall as fit for viewing, and few get to visit the unauthorized sections. Fewer still are aware of the existence of at least one part of the Wall that remains in almost original condition, nearly 1,500 years after construction of legendary fortification began. But there’s a good reason for this – it’s underwater.
American journalist Steven Schwankert has been diving since age 10. It was though his setting – up of a diving school that Schwankert came to explore some of lesser – known areas of China’s lakes – and discovered the underwater Wall under a reservoir. “The most fascinating piece of diving I ever did in China must be the Great Wall. I managed to find out about it via the Internet. It wasn’t difficult to get to Pan Jiakou in Hebei Province, near the East Qing Tomb about 4 hour’s drive from Beijing. Why do I want to dive the Great Wall? Why do people want to walk on the Great Wall? It’s the same answer.”
There are, however, advantages of visiting the Great Wall in a diving suit over being on foot. The water acts as a preservative by preventing the kind of mass tourism that has brought trouble on other parts of the Wall. “Unlike the people who walk in the Wall, we as divers never need to actually touch it. I’ve dived twice there, the last time in July. I found that the water then was much deeper than it was before – 13 meters deep.” When he first dived, parts of the Wall were visible above the surface. Now even the guard tower is completely submerged. “It’s better that the Wall is deep under water, as there are lots of boats coming in and out around that area. Their wave action could potentially damage the brickwork. So, the deeper, the better.”

第三部分：阅读理解（共20小题；每小题2分，满分40分）
Put yourself in these tourists’ position. You are walking an icy mountain path in the Alps in Europe. Suddenly you spot a body on the ground, face downward and stuck to the ice. You think someone may have been murdered or in a fatal accident. So you rush back and call the police. The police, however, quickly realize that this body is different from others they’ve found on the mountain. For one thing, it is mostly undamaged. For another, its skin is dried out, like a mummy’s（木乃伊）. And there is an old small stone knife beside the body.
The body turned out be much older than the tourists could have guessed. When specialists（专家）had a chance to examine it, they discovered it had been there for about five thousand years!
How could a body stay preserved for all this time? Two things probably helped. First, the place where the man died was somewhat sheltered, so animals couldn’t get at it. Then he was quickly covered by falling snow. Wind blowing through the snow probably “freeze-dried” his body, removing all moisture(水分) from it.
Objects found with the body told something about the Iceman’s life. He wore a well-made fur jacket and trousers. He clearly had been hunting, because he carried arrows, and animal bones were nearby. He also had a grass cushion for sitting or sleeping on. Perhaps he was tired when he lay down for the last time.
The body was found in 1991, when some of the ice on the mountain melted. Searching for the cause of the Iceman’s death, scientists put the body back into cold conditions---and hoped.

C. The body is much older than others.   D. The body is mostly undamaged.
3. At what time of a year was the Iceman probably died?
A. Early fall.   B. Late spring.    C. Summer.    D. Winter.

The world’s biggest Internet search engine, Google, has proven once again to be king of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.

  Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.

  A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.

  The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.

  Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.

  In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.

Wi-Fi is not available in cities without_____.

 A. a computer   B. a radio   C. a hotspot   D. a cell phone

Which of the following is NOT the advantage of Wi-Fi?

The high speed Internet connection.   B. Many free Internet phones.

Using the same computers for Internet phones when you go to other places. C. Used in all the US cities.

Some scientists started to call Wi-Fi 4G, because_____.

A.it is the product of the Google”s 4^th generation.

B..it is more capable of sending information than the mobile phone network.

C.it has been used by more than four generations.

D.Wi-Fi will surely take the place of the mobile phone network.

. Which of the following is the best title?

A.Third Generation Telecommunication Technology

B. Free Call Service

C.Google Launches Free Wi-Fi Service

D.Free Wi-Fi Service across the U.S.A.
