This year, the World Wide Web has turned 25 years old. What many people don't know is that the web was at first created to improve communication between thousands of scientists in Switzerland. In 1989, Tim Berners-Lee was a 34-year-old British physicist working as a software engineer at CERN, the European Organization for Nuclear Research in Switzerland. Since CERE was a huge organization with thousands of scientists, communication between them was becoming increasingly difficult. Berners-Lee wanted to develop a system to solve the problem. His paper suggested an information system, where a page on one computer could have a link to another page on another computer ( connected through the Internet) allowing scientists to read lots of information quickly. However, Berners-Lee's boss said that it sounded exciting but impossible. Even though there were many difficulties and few supporters, Berners-Lee went on to develop the World Wide Web. He came up with ideas such as Hyper-text Transfer Protocol to allow computers to talk to each other, Hyper-text Markup Language (HTML) to create the pages, a server to serve the pages, and a browser to see them. In December 1990, the World Wide Web was demonstrated and in 1991, the WWW project was made public, so that other programmers could develop their own browsers. Berners-Lee believed that it could be used for more than scientific purposes. He wanted the Internet to be easy for anyone to use-a free open software. His wishes soon came true. Although the World Wide Web has today turned into a completely different thing from what it meant at first, it has become necessary and important to our lives, powering our mobile technologies and the way we get information. Question: According to the text, Berners-Lee_. Options: A: doesn't give up easily when in trouble B: has worked at CERN for 25 years C: is a 55-year-old Swiss physicist D: knows little about the Internet

In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years. After China's first satellite into the Earth's orbit in 1970 came four flights of unmanned Shenzhou missions from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China's second human spaceflight, was launched, with a crew of two astronauts. What's more, the landmark spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration. Meanwhile, China's moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world's first man-made satellite, China's first circumlunar satellite Chang'e 1 took off on Oct.24, 2007, which became another milestone in China's space achievements after the above-mentioned manned flights. Chang'e 1 was expected to fulfill four scientific goals, one of which was to probe mineral elements on the moon, especially those not existent on Earth. It's said that the lunar regolith is abundant in helium-3, a clean fuel that may support the Earth's energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the blasting off of Chang'e 2, China's 2nd unmanned lunar probe, marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang'e 3 and Chang'e 4, as a preparation for a soft lunar landing in the future. With great expectations, people all over the world are looking forward to China's greater space achievements. Question: What can be the best title for the text? Options: A: Ancient Chinese's Dream B: China's Major Space Achievements C: China's Moon Exploration D: The World's Great Expectations

If you pay attention to those things, you'll find you are able to easily understand how your dog is feeling. Ears and face The head of a dog is more expressive than you think. If you say a word that he recognizes, like his name or something you say often, his ears will get up. His mouth is another good instruction. A mouth that is wide open to pant with some sound suggests that the dog is happy -- some people even say when a dog is panting, he is laughing as he cools himself. A tongue sticking out suggests that the dog is in a good mood. Eyes To a dog, purple and blue are both seen as shades of blue. Red is seen as black or dark grey. Orange, yellow and green are seen as various shades of yellow. This means that, to a dog, bright orange toys are the same yellow shade. If you want your dog to clearly see his toys in the green grass you'd better give the dog blue toys; if you have orange, yellow or green toys, the dog will be able to find them with his nose. Nose A dog can both sniff and breathe through his nose. Breathing is for air, but when dogs sniff with short breaths they are actually following some scents with his keen nose. When a dog is overheated, his sense of smell is reduced by as much as 40 percent and he uses the air to cool himself rather than for smelling. Puppies' noses can help find their mother when their eyes and ears are closed. The function will disappear by the time they are adults. Tail Lastly, you need to pay attention to your dog's tail, because it shows what he is thinking and feeling. A dog that is in a good mood will have a tail that seems to be going a mile a minute -- wagging, and excited. However, an angry or frightened dog will have his tail between his legs. Question: Which of the following is TRUE according to the last two parts "Nose" and "Tail"? Options: A: Adult dogs can't use their nose to find their mothers. B: When a dog feels too hot, he will lose his sense of smell. C: Dogs often sniff with short breaths when they feel sad. D: A dog's tail can't show his feelings unless he is frightened.
