If you’re ever in central London between Covent Garden and Holborn, look up. You might spot three letters somewhere between the Starbucks angels and the pub signs: "LSE". They may not look much. But these three letters welcome you to one of the world’s leading universities for social and political sciences. The London School of Economics and Political Science (LSE) offers more than just economics. You can study all sorts of things, from history to mathematics to psychology. The university was founded in 1895. It has always set very high standards for its students. Today, it accepts fewer students every year than any other British university. It’s not surprising that 17 Nobel Prize winners and 34 world leaders went to LSE including John F. Kennedy. Those who do get a place can enjoy teaching from LSE’s top-class staff. Students have the chance to learn in the university’s great facilities. The LSE has the world’s largest social and political sciences library, its own theater, and many other lecture theaters. These host lectures and debates for both students and the public. Some of the most important people in the world come to speak. Recent speakers have included former UN Secretary—General Kofi Annan, former US President Bill Clinton, and even ’controversially’ Colonel Gaddafi. In 2008, the LSE started "LSE Live", a series of live online lectures. There’s still time for fun at LSE. Students can join up with the LSE student union to take part in sports, arts and drama clubs. They can also join up with other London universities. What’s more, LSE is big on China. The university has a strong link with Peking University. A two-week LSE—PKU summer school takes place every year. The course covers economics, management, international relations, media and law, all with a focus on China and Asia. How’s that for strengthening East-West relations Why does the author mention Kofi Annan, Bill Clinton and Colonel Gaddafi

B. To provide examples of" famous speakers.
C. To introduce LSE’s outstanding graduates.

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hunted animals. They used to paint pictures of the animals they wanted to catch. Pictures of this kind have been found on the walls of caves in France and Spain. No one knows why they were painted there. Perhaps the painters thought that their pictures would help them to catch these animals. Or perhaps human beings always wanted to tell stories in pictures. About 5,000 years ago, the Egyptians and other people in the Near East began to use pictures as kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet. The Egyptians used to record information and to tell stories by putting picture writing and pictures together. When an important person died, scenes and stories from his life were painted and carved on the wails of the place where he was buried. Some of these pictures are like modern comic strip stories. It has been said that Egypt is the home of the comic strip. But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it. By the year 1,000 BC, people who lived in the area around the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letters of the Greek alphabet. The Romans copied the idea, and the Roman alphabet is now used all over the world. These days, we can write clown a story, or record information, without using pictures. But we still need pictures of all kinds: drawing, photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the street, and on the walls of the places where we live and work. Pictures help us to understand and remember things more easily, and they can make a story much more interesting. The best title for this passage is ______.
A. Pictures in Old Time
B. Pictures, a Kind of Writing
C. Pictures and Alphabet System
D. How Alphabet Comes into Being
