Time spent in a bookshop can be most enjoyable, whether you are a book-lover or only there to buy a book as a present. You may even have entered the shop just to find a shelter from a sudden rain. Whatever the reason, you can soon totally unaware of your surroundings. You soon become interested in some books or others, and usually it is only much later that you realize you have spent too much time there and have to rush off to keep some forgotten appointment.
　　This chance to escape the realities of everyday life is, I think, the main attraction of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can walk around such a place as much as you wish. If it is a good shop, no assistant will come up to you with the greeting “Can I help you?” You needn’t buy anything you don’t want. In a bookshop an assistant should remain in the background until you have finished reading. Then, and only then, are his services necessary.
　　Once, a medical student had to read a textbook which was far too expensive for him to buy. He couldn't borrow it from the library and the only copy he could find was in a certain bookshop. Every afternoon, therefore, he would go along to the shop and read a little of the book at a time. One day, however, he was disappointed to find the book missing from his usual place. He was about to leave, when he noticed the owner of the shop beckoning to him. Expecting to be told off, he went towards him. To his surprise, the owner pointed to the book which was tucked (folded beautifully) away in a corner. “I put it there in case anyone tries to buy it,” he said, and left the delighted student to continue his reading.

Like many people ,I have no clear idea about heroes . A t some point , we all wonder if we need a hero and what a hero really is.
Although there are a lot of differences in cultures, heroes around the world generally share a number of characteristics (特点) which give us courage  and make us want to learn from them.
A hero does something worth (值) talking about, A hero has a special story to tell and people think highly of it. But a hero is not just person with great fame (声誉).
A hero has power(力量) larger than himself . Some people want to live like a hero. And they have to experience life with new and further meaning .A sure test for would- be heroes is what or whom they serve. What do they want to live and die for? If their answer suggests they serve only own fames, they may be famous persons but not heroes.
A hero has a vision from the mountain top .He has the power to move people . He creates new possibility. Without Gandhi, India might still be part of Britain, Without Martin Luther King .Jr, Americans might take different parks , and shop in different stores of the different colors of their skins.
There might be changes in society without a hero, but the speed of the change would be rather slow . Thanks to heroes in history ,they make the society develop so rapidly.
