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 .And 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?

专四英语作文 篇3

My younger cousin got in trouble at school for kicking some other students. When asked why he did it, he responded that he had been imitating his favorite cartoon character. He had seen this behavior and decided to act similarly. His parents had enormous difficulties getting him to stop. This showed me that TV shows can be more influential than parents. Finally, young people often feel like they have nothing in common with their parents, so their parents' influence in their live decreases. Young people think their parents do. For example, many parents are not as proficient as their children are at using modern technology. They might not even know how to surf the Internet or use an MP3 player. This gap in knowledge makes it very hard for them to find common ground with their parents. In conclusion, modern media and the world of technology have much stronger influences on young people than their parents do. As young people get more absorbed in television, movies celebrities, and their friends, parents should expect to continue losing more control over their children.Many believe that outside influences have stronger effects on young people than their parents do. This, however, is a mistaken belief.

我弟弟在学校里遇到了一些其他学生的麻烦。当被问到他为什么这样做时，他回答说，他一直在模仿他最喜欢的卡通人物。他已经看到了这种行为，并决定采取同样的行动。他的父母给他带来了巨大的困难让他停下来。这说明我认为电视节目比父母更有影响力。最后，年轻人通常觉得自己和父母没有共同的生活，所以他们父母的生活会影响他们的生活。年轻人认为他们的父母。例如，许多父母不像他们的孩子一样熟练使用现代技术。他们可能甚至不知道如何上网或使用MP3播放器。这方面的知识差距使他们很难找到共同的立场与他们的父母。总之，现代媒体和世界的技术对年轻人的影响比他们的父母更强烈的影响。随着年轻人对电视、电影明星以及他们的朋友的影响，父母应该继续失去对孩子的控制，许多人认为，外界的影响对年轻人的影响比他们的父母更为强烈。然而，这是一个错误的信念。

专四英语作文 篇4

Just as is revealed in the pictures above, people are generally classified into two types: the pessimistic and the optimistic. We can see in one picture some people, long-faced and downhearted, are counting the nights by the shadows while in the other picture the happy-go-lucky people are enjoying the starry nights. What a contrastive view! Remember, it is not the bad thing that determines our state of mind but the way we look at it matters. (描述点题段) (以小到大)

An example that comes to mind is SARS crisis that has recently torn apart and ravaged most of China. Admittedly, it has cost us quite a lot. Some people suffered from health damage and still some even lost their lives. And our economy suffers a temporary setback and a slowdown. However, we still have learnt and benefited a lot from it. (举例说明段) 4. First things first, we are more concerned than never before with our health, and the environment we live in. Additionally, we tried and bettered and are still bettering our mechanism to respond to unexpected crises. These and other lessons at the expense of blood, tear, toil and sweat are benefiting and continue to benefit us and generations of Chinese to come. (分析问题段)

The best way to overcome the frustrations brought about crises is to always take a positive outlook on life. Just as a well-known ancient Chinese notion goes, the past lessons if not forgotten are good teachers for us all. If we can bear in mind sufferings and ordeals we have experienced, then our sufferings will not go unrewarded. (前瞻感言段)
