The Internet

With the development of information technology, surfing on the internet becomes more and more popular in people's everyday life. People can complete a great deal of complicated work and communicate with each other by network. Network refers to the internet and information included in it, which provides an opportunity for people to gain useful information they need. Meanwhile, people greatly improve their working efficiency with a computer. However, there is a lot of information on the internet which not only contains good information, but harmful information as well. Is the network good or bad for our life? The answers to this question are diverse.

Some people think that network is good for their everyday life, for it caters to their inclination. They browse the internet for capturing related information and downloading files according to their needs. For example, to work and study, they are accessible to academic web site to search articles no matter which country they come from. As for entertainment, they can also download musics and movies from web site to their computers. For this reason, many people are fascinated with the internet and keep their computer at hand when they encounter

any problem. They certainly believe that the internet is a helpful tool for their daily life.

Some other people however, think that network is harmful to their daily life. Because there are many pornographic websites on the internet which can mislead a lot of people ranging from Children to adults. There are also some cheating information and annoying advertisements they can not get rid of. So, they are afraid of suffing on the internet. They confirm that the internet will destroy their life.

I think that the internet is very helpful for our daily life. Networks have made it possible to capture the attention of millions of people. Not only does it broaden our view, but bring us some useful information. As for junk information, however, our government ought to take strict measures to restrict and filter it. We should not click nasty webpage. If our government and we does it well, I fully believe that the internet will provide more convenience for us. Whether you like it or not, network has come closer and closer to you.

Manners are important to happy relations among people. No one likes a person with bad manners. A person with good manners never laughs at people when they are in trouble. Instead， he tries to offer help. When he asks for something， he says “please” and when he receives something， he always says “thanks”。 He does not interrupt other people when they are talking. He does not talk loudly or laugh loudly in public. When he sneezes or spits， he uses a handkerchief. As a sutdent， it is a bad manner to come late to class. If you are late you should say “I＇m sorry.” to the teacher at the time or after class

Good manners mean good behaviour in social communication. A person with good manners is always agreeable companion, because he is always thinking of others and respect others. He will not push through a crowd, but wait quietly for his turn to advance. Good manners are not the exceptionally great deeds but they can tell that the person who possesses them is a man of highest standards.{一篇关于做梦的英文短文}.

To learn good manners, one must first of all bear in mind that they arise from one’s daily behaviour—the way he responds to others and the manner he behaves in front of people. To be a man of good manners, he must be genuinely polite to others and show respect for others. In short, politeness costs nothing and gains everything.

Good manners are about respect. They are what makes a society function smoothly: it is the lubricant for social interaction. We are living in a society after all!

Showing good manners, using please and thank you, smiling and greeting someone etc are all ways of showing respect for the person you are interacting with and indicating in a subtle way to them that they are important to you and that you are acknowledging their feelings. Everyone wants to feel acknowledged and respected. All

social situations would be more pleasant if people would show this kind of consideration for each other.

Good manners have fallen by the way side in life today as our culture is more concerned with speed over substance, getting things done more quickly, at the expense of quality or care. It is faster to push someone out the way, whether physically or emotionally, than to bother to take the time to respect them , to put in a bit of effort to be pleasant. This is all part of our 'fast food' culture and the 'me me me' culture. Parents often seem to put their children in front of the TV rather than spend time with them, teaching them how to go on in life. And of course children learn how to treat others and talk to them from watching their parents. So the decline of manners continues.

How much does it cost you to say thank you? Or to add the word please onto the end of a request? How nice does it feel when someone actually smiles at you or takes the trouble to say hello? In actual fact it also feels nice to be the one to bestow a kind word, it feels great, a bit like giving to charity. It can brighten a person's whole day if they are feeling bad abotu anything. It reminds them there are good people out there, that people do care, that society does still exist. It feels warm and friendly to both parties.

This is a problem at work too, with senior managers not bothering with the 'little people', why greet them or make them feel special when they are that unimportant to the company? But be nice to those you meet on the way up, you may just see them again on your way down. And the words 'to the company' are the ones to think about. It is not about the company it is about one human being to another. We are all together on this earth, as equals, so let us be nice to eachother – it will make us all have a happier day!

Good manners are simply respect and consideration for others or being aware of the needs of others. They are the oil which creates a happy and successful society. If children are not taught good manners they think that they are the most important people in the{一篇关于做梦的英文短文}.

manners begins with parents but it doesn't end with parents, teachers too can help but so too can everyone. Set an example today, open that door for that lady with the pushchair behind you, give your seat up on the bus for that elderly lady with the big shopping bag, ban the TV advert where a man shouts loudly about windows and while we're about it let our politicians debate the issues without making personal attacks on one

another.

the importance of good manners

Good manners play an important part in maintaining peace and good-wiling in a community. A man who has good manners does not hurt the feelings of others, and therefore he is on good terms with his friends and neighbors and also with others. In this way he helps to keep peace in society.

But a man whose manners are bad has no respect for others. He uses words carelessly and behaves rudely towards other and causes a lot of ill-will and unpleasantness. In the end, it is he himself who suffers the most. Everyone avoids him and he is forced to live almost in isolation.

To live well in a society, money alone is not enough. We should also have good manners, for it is human nature to seek friendship; and friendship cannot be bought with money. Friendship with others makes life pleasant and it has to be earned through our own attitude towards others. If we are kind to others, they will be kind to us, and kindness is the essence of good manners. Bad manners not only drive away friends but also others, including our own family members.

Even the richest man cannot afford to have had manners. For a man may have enough money to buy all things than he wants; but if his manners are bad he will have no friends, and no one can live happily without friends. Even the members of his own family may not respect him and finally he will become a lonely man.

On the other hand, a man whose manners are good has many friends. He commands the respect of all those who come into contact with him. He does not talk ill about others. Even when he is provoked, he tries his best to use words in a way which will not offend others. He is also sympathetic towards the weak and ignorant and does not poke fun at the deformities and weaknesses of others.

There are, however, many people who behave so well outside their homes that they are respected and admired by everyone outside. But in their own homes they are worse than the devil. Such people could not be said to have good

manners. Their whole behavior is a pretence and it does not take long for others to discover this.

If one’s manners are good, one behaves well everywhere, even when one is away from the critical eyes of others. Only such a person can live well in society. It is therefore essential for everyone to cultivate good manners.

篇五:《关于成功的一篇英语文章》

这是一篇我很喜欢的关于成功的英语作文

TO Success: Opportunity or hard-working?

Every body wants to succeed. But when it comes to the question that which factor leads to success, opportunity or hard-work, different people will offer different answers.

Some people think that opportunity is the first factor leading to success. They hold the idea, as a proverb saying, “Man proposes, god disposes”. Because almost all successful people have good luck and have caught their valuable opportunities, they believe that opportunity is a leading condition of the success. If seizes and makes the best use of opportunity available, one can succeed surely. In summary, to them, chances and lucks play the most important role on the road to success.

However, others maintain that “no pains, no gains” .Without exerting oneself, one could never expect to achieve success in no matter what one is doing. As is known to all, there is no royal road to the summit of success. One is likely to succeed only when one has worked with whole-hearted devotion and perseverance. Those who are lazy, sloppy and indifferent to their work, those who never concentrate on work will definitely end in failure. On the whole, as far as they are concerned, hard-working is the decisive factor to success.

In my view, both hard work and opportunity eventually matters. They are inseparable from each other, and put together, they make a great success. Hard work is to luck what fish is to water, and can be seen as an interior precondition of success. It lays the corner-stone for building a house while luck serves to cement it, to make the building bricks adherent to one another. They are the twins that contribute to success together. They are the factors from within and without respectively. We must work hard, make efforts and get prepared. When opportunities come, meet and make full use of them. Only in this way can we succeed one day.

篇六:《一篇关于常见计算机术语的英文短文》{一篇关于做梦的英文短文}.

Computer technology has become a major part of people's lives. This technology has its own special words. One example is the word mouse. A computer mouse is not a small animal that lives in buildings and open fields. It is a small device that you move around on a flat surface in front of a computer. The mouse moves the pointer, or cursor, on the computer screen. Computer expert Douglas Engelbart developed the idea for the mouse in the early

nineteen-sixties. The first computer mouse was a carved block of wood with two metal wheels. It was called a mouse because it had a tail at one end. The tail was the wire that connected it to the computer.

Using a computer takes some training. People who are experts are sometimes called hackers.

A hacker is usually a person who writes software programs in a special computer language. But the word hacker is also used to describe a person who tries to steal information from computer systems.

Another well known computer word is Google, spelled g-o-o-g-l-e. It is the name of a popular "search engine" for the Internet. People use the search engine to find information about almost any subject on the Internet. The people who started the company named it Google because in mathematics, googol, spelled g-o-o-g-o-l, is an extremely large number. It is the number one followed by one-hundred zeros.{一篇关于做梦的英文短文}.

When you "Google" a subject, you can get a large amount of information about it. Some people like to Google their friends or themselves to see how many times their name appears on the Internet.

If you Google someone, you might find that person's name on a blog. A blog is the shortened name for a Web log. A blog is a personal Web page. It may contain stories, comments,

pictures and links to other Web sites. Some people add information to their blogs every day. People who have blogs are called bloggers.

Blogs are not the same as spam. Spam is unwanted sales messages sent to your electronic mailbox. The name is based on a funny joke many years ago on a British television show, "Monty Python's Flying Circus." Some friends are at an eating place that only serves a processed meat product from the United States called SPAM. Every time the friends try to speak, another group of people starts singing the word SPAM very loudly. This interferes with the friends' discussion – just as unwanted sales messages interfere with communication over the Internet.

篇七:《一篇关于英语颜色词green及其文化内涵的英文短文》

Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished.

For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns had not yet developed.

A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today – a person who is new in a job.

About one hundred years ago, greenhorn was a popular expression in the American west. Old-timers used it to describe a man who had just arrived from one of the big cities back east. The greenhorn lacked the skills he would need to live in the hard, rough country.

Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds.

A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

Green is also the color used to describe the powerful emotion, jealousy. The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play "Othello."

It describes the unplesant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay raise and she does not.

In most places in the world, a green light is a signal to move ahead. A green light on a traffic signal means your car can continue on. In everyday speech, a green lightmeans approval to continue with a project. We want you to know we have a green light to continue this series next week.

篇八:《一篇关于downloading essays 的英语作文》

Nowadays, downloading essays are more and more popular and acceptable among students. From my perspective, downloading essay is like a double edged sword, there are both advantages and disadvantages.

I think the foremost advantage of downloading essay is that it provides initial learners with a masterplate. Then they could conclude the writing skills by skimming plenty of downloading essays.

篇九:《关于P450的一篇英文文章翻译》{一篇关于做梦的英文短文}.

人参皂苷合成途径中催化达玛烯二醇合成原人参二醇的细胞色素P450酶——CYP716A47

摘要：人参是一种有名的中药，且在它的根中含有药理活性成分——人参皂苷。人参皂苷是四环三萜皂苷的一种，被认为是由达玛烯二醇经过细胞色素P450羟化和糖基转移酶糖基化后形成的。然而，还没有编码羟基化和糖基化的基因被鉴定出来。本文，我们鉴定了一个原人参二醇合酶，该酶为细胞色素酶，通过对达玛烯二醇的碳12位进行羟化作用形成原人参二醇。从由茉莉酸甲酯诱导后的人参不定根的EST序列中筛选到9个假定的细胞色素序列。因为CYP716A47不止在茉莉酸甲酯诱导后表达量提高，且在过表达角鲨烯合酶，皂苷高产的转基因人参中表达量也很高，因此被认为是原人参二醇合酶。体外实验证明CYP716A47催化达玛烯二醇合成原人参二醇。在酿酒酵母WAT21中异源表达CYP716A47，可催化达玛烯二醇合成原人参二醇。另外，在不添加达玛烯二醇的情况下，在酵母中共表达，达玛烯二醇合酶基因和CYP716A47基因，能生成原人参二醇。由达玛烯二醇形成的原人参二醇结构式通过液相色谱联合大气压化学电离质谱进行分析鉴定。因此，CYP716A47是一个催化达玛烯二醇合成原人参二醇的达玛烯C12羟化酶。

关键词：CYP716A47；细胞色素 P450；达玛烯二醇；人参皂苷；原人参二醇

1、前言

三萜皂苷是高等植物中异戊二烯类的次生代谢产物。在不同种类的植物中它表现出结构和生物活性的多样性。这些分子具有可观的商业价值且很多已被用作药物。植物中人参皂苷的天然功能被认为可能与防御病原菌和害虫攻击有关。三萜皂苷的基本骨架有齐墩果烷型，乌苏果烷型，羽扇豆醇型和达玛烷型。

人参因为它对癌症，糖尿病和神经退行性等疾病有显著的药理活性而闻名。人参皂苷是人参根中的主要生物活性成分。人参根中至少含有其干重4%的皂苷。人参皂苷的主要成分是七个达玛烷型的四环三萜皂苷（人参皂苷Rb1, Rb2, Rc, Rd, Re, Rf 和Rg1）和一个含量很少的齐墩果烷型皂苷Ro。根据苷元的结构达玛烷型皂苷又分为两组：原人参二醇型（Rb1, Rb2, Rc, Rd）和原人参三醇型（Re, Rf 和Rg1）。在三七和绞股蓝中的主要皂苷成分也为达玛烷型的。

达玛烷型皂苷合成的第一步是由达玛烯二醇合酶催化2,3-环氧角鲨烯环化形成达玛烯二醇-
