Buying or Borrowing Books?
Books are close friends of humanity. They can arm us with knowledge and information we need to make success of life. Through books we can obtain skills and techniques for survival and development. Through books we can enlighten our spirits and live a fuller life. There are generally two ways in which we can have access to books: borrowing or buying. While millions are borrowing books, I still think buying them best suits me and gives me the greatest enjoyment.
Admittedly, there are a few merits for borrowing books. For one thing, borrowing books can save us huge amounts of money. And of course, with the money saved we can do other more worthy things also, as we borrow books from the library and friends, we normally have deadline to finish them, and consequently we can read more books in a limited time. And we can, above all, better our efficiency of our reading, just as a famous Chinese saying goes, “books can not be read unless borrowed.”
However, some advantages for buying books are more obvious and compelling. One of them, definitely not shared by the choice of borrowing books, is the abundance of freedom that buying books can offer us. Since we can keep the books as long as we wish, we can read as much as we want. Another strength of owing books is that we can take whatever notes on the margin of the pages of the books. And finally, the process of selecting and keeping books can be a great fun that borrowing books can by no means offer.
While borrowing books can, to some extent, quench our thirst for knowledge, buying books gives us greater pleasure of selecting and keeping the best of the world treasure. Can we think of any thing else more delightful and rewarding?

Crisis is to our life what illness is to our body. Just as fatal disease can destroy our body and sometimes even put an end to our lives, so does smashing crisis knock us down so hopelessly that we might never have chance of standing up again. However, most crises that frequent us in life are not such category. They, like occasional ailments which sometimes can bolster our body's immune system, are mostly minor and surmountable and therefore making us hardy enough to survive whatever adversities in our later life. Even those serious crises, if handled properly, can be turned to a blessing to us, too.
As far as a nation is concerned, crisis can be rendered beneficial. Take Wenchuan earthquake which shook most of Sichuan recently for example. The crisis has cost us Chinese a lot. Houses collapsed, bridges broke down and many affected areas were cut off from the outside world. Nearly a million people lost their homes, ten thousands of people were injured and another ten thousands of people were killed. But our sufferings won't go in vain. Scientists are more determined to improve the means by which we forecast earthquakes with more accuracy. We should build houses which can survive the destructive earthquakes. And we also should better the mechanism to face the emergencies and crisis.
As for economic life, crises are not always rendered bad. During these times, we can stop the race of fast economy to speculate about some fundamental issues of humanity such as how much high-speed development in this way can contribute to the well-being of human life. Just take my own country for instance. Of course, in the past two decades or so, our economy has gained the highest speed man has experienced. But haven't we paid too much? Our rivers are polluted. Our natural resources are shrinking. Our national power of creation is drained. Is it worthy of it? Isn't it high time we gave it a serious thought? Shouldn't we stop making ourselves long in quantity and short in quality? And chance of deep thought has come with this crisis, which is now deepening in most parts of the world.
Crisis sometimes contributes to our life treasure in a way that few can imagine. It can weather us and make us strong enough to face ourselves when we feel weak. Eric, my uncle is a case in point. He had hard time in his childhood going through such a fatal disease that he had never thought he could survive. He was in due course saved by doctors. Ever since then he regarded his life as a second given by God and has been so grateful to the world that he has been doing whatever he can to give back in the same measure to other fellows. And now he is living a happy and successful life.
As a well-known ancient Chinese notion goes, the past lessons if not forgotten can be good teachers for us all. If we can bear in mind the various sufferings and ordeals we have experienced, then our sufferings will not go unrewarded and those of our compatriots who was killed in the earthquake did not die in vain. We should take the lessons from crisis and regard them as a chance for new growth.
