Human brain is the most complex and intelligent mechanism in the world With our brain we get to know the world and make a good u of the world to our benefit Other things can be ud up, but ud properly, our brain can never be exhausted Excessive u of the brain, however, will caua lot of problems. First, handwork or physical labor is good exerci as well as rest for our brain Secondly, we should avoid doing brainwork for long hours on end A long period of brainwork may cau, through lack of bodily activity, slow blood circulation and inadequate oxygen supply to the brain, resulting in inefficiency and possible damage to the brain.
Nowadays,as we enter a new era which is full of new thing and technology, computer usinghas been a common and necessary skill in our work and study. However, computer alsohas some advantages while it has caud some problems.
Onthe one hand, to a large extent, computer has brought a lot of convenience andbenefits to our work, study and other areas. For example, tho people who arefamiliar with computer using not only have more chances to get in touch withmore information and knowledge but also have more efficiency in their study andwork, especially for university students and technical workers. On the otherhand, computers have made a great contribution to the development ofcommunication. We can communicate with others who come from different places bycomputer but without meeting with them in person as a result.
However,on the other hand, there are some problems caud by computer using. Forexample, a flood of the computer games have been a great threat for the growthand development of some children and students, and even some adults. They areaddicted to computer games so terrible that they can never concentrate on theirstudy and work but only play games day and night. It has been a tremendousworry for their parents.
Takingits advantages and disadvantages into consideration, I suggest that we takefull u advantages of its advantages and avoid its disadvantages as much aspossible.
As is shown in the chart, cell phones are becoming increasingly popular within China. In 1999, the number of cell phones in u was only 2 million, but in 20xx, the number reaches 5 million. And in the year 20xx, the number has suddenly soared to 9 million.
There are many factors contributing to this development. Firstly, a cell phone has no wires and can be carried everywhere easily. Secondly, a cell phone is something wonderful that we can have fun with news, games, music and chat through nding short messages. Thirdly, the drop in price and the simultaneous improvement in the functions have made it possible for an average person to make u of cell phones.
The wide u of cell phones has made them more and more indispensable in peoples daily life. The many functions of the cell phone have made certain people reluctant to parate them- lves from their cell phone.
In your country, is there more need for land to be left in its natural condition or is there more need for land to be developed for housing and industry?
With a population accounting nearly for one quarter of the world population, my country, China, has been suffering from rious loss of arable land, which now hardly accounts for 7% of overall arable land of the world. Yet some people simply did not realize that land loss is so crucial that we one day might incapable of averting that catastrophe if we now clo our eyes to it.
Industrial development without careful consideration regarding land prervation has caud problems more rious than people can ever imagine. Take the great Sanxia dam for example, which will be put into operation next year. While the country benefits from gargantuan potential of electricity generation, we have to face up to various environmental conrvation issues concerning geological and ecological environment along both river sides and whole upper reaches. The professional designers of the great dam now have to work out a practical way to prevent and remedy pollution effectively, which has already been the focus of world attention.
After the entrance of the WTO, industry development is more and more important for our country, yet we should be careful about the pollution which is inevitably caud by industry. Recent surveys have shown that refu treatment engineering is not well financed in China, while attentions are drawn to tho much more obvious achievements. Industrial pollution accidents occur far more frequently in our still developing country than in other more advanced countries. Urban population also produce astoundingly large amount of pollution. Today the alleged white pollution is creeping all over the country – people throw plastic bags, films everywhere, never feeling anything wrong.
We no doubt need land either for natural condition or for industry, and it ems we need more if posssible. Nevertheless, we live in a world where everything has its cost, and some day in the future, I believe, we will inescapably pay for what we have ignored.
This picture portrays such an ironic situation: on the road, stands a man, who is completely concentrating on his cell phone whereas using a stick for direction, which implies the unprecedented popularity or even overusing of cell phones nowadays.
Exaggerated as the picture is , the phenomenon behind it is rather thought-procking. With the development of high-tech equipment, especially smart phones, people in growing numbers tend to become addicted to the excessive u of them. According to a survey carried out in China Daily veral days ago, almost 47% of citizens explain that they would experience certain kind of anxiety without cellphones at hand. Meanwhile, the overusing of cellphones, firstly, would exert detrimental impact on the health of us. What’s wor, it would perform a negative character in interpersonal relationship since we have less time to communicate.
Judging from the evidence above, certain measures should be taken. Firstly, certain institutions in China should launch relevant campaigns to limit the excessive ust of cellphones. Moreover, we ,as college students, should put emphasis on it right from ourlves as a start.

I'm a nior high school student named Li Hua. Now many students have iPads and think it's a fashion to u them.Using an iPad,we can learn English, download a lot of learning materials and read them on the screen.Apparently,it's helpful to our study.Some students,however,bring their iPads to the classroom and listen to music without earphones,which makes other students greatly annoyed.Some of them even waste precious time in class playing video games.In my opinion,as students,we should make good u of iPads to help our study.The classroom is a place for students to study,and therefore concentration is awfully needed.Furthermore,the school should make a rule to guide students to u iPads in a proper way.Yours sincerely,Li Hua
Recently，we did a survey on how student spend their pocket money among 2000 stuent …
Recently, a survey has been done on how middle school students spend their pocket money. according to the results, 55% of the students spend their pocket money on their study, such as buying reference books. About 27% u their money for food and drink. While the rest spend their money on entertainment, for example, surfing the Internet and playing PC games.
Since students are consumers, not producers, they should u the pocket money wily and properly. Buying books or saving money to help tho in need is a good way. In addition, it is meaningless and uless to spend much money on unnecessary entertainment.
Anyway, it is not easy for our parents to earn money, so we students should learn to u money carefully.
Nowadays, experimental usage of animal has become a widely concerned issue around the world. People hold diver views towards it.
Adversaries claim that it is an extremely crude behavior. Animals, especially mammals, like dogs, cats, rabbits, rats, which are the major victims in the experimentation, are usually human’s pets.
Pet owners are strongly against it for they firmly believe that animals suffer physically and mentally as we do. When equality is advocated in the modern world, it is inhuman to disrespect creatures that are not human beings.
Furthermore, a number of experts pointed out that it would be at high stake of depending on the results of animal experiment; since they differ from us in many ways.
Take the body structure for example, we can’t imagine humans try to jump from the height of nine stories without any protection becau cats survive out of the same test.
Tho in favor of the idea about usage of animal declare that using animal is an advisable choice.
On one hand becau their bodies are similar in function to ours. For instance, they catch colds, suffer from stomachs and heart dias, which more importantly influenced by diet and habits.
The conquences of the test may not be applied to humans, although they are highly connected to the human situations. On the other hand, tho creatures yell and act abnormally when they feel uncomfortable, which is what exactly rearchers expect. In addition, there is an easy-to-answer question:isn’t it crueler to test directly on people with little knowledge on the objects’ effects? In a word, there is nothing better than animal that remble human the best for experiment.
Personally, I am not a supporter of animal experiments, yet there is anything more suitable can replace them, I accept using animals for tests, but take good care of them when they are not in the laboratory.
Nowadays,with the rapid development of IT and information industry, cell phones play a dominant role in towns people's life. But, like everything el, they have both favorable and mffavorahle aspects.
First, it's uful. As a wireless mobile telephone, it's easy and handy to early to wherever one goes and call the callee however far away he is. Therefore, it greatly facilitates people's life. Second, it's convenient. Whenever one meets trouble or something urgent, one can nmke a call immediately. Most important of all, it's a very helpful companion. With a multirfunction cell phone in hand, one can easily get on the Net, browsing the uful information, conducting e-commerce and doing whatever one can do via Internet.
However, just as everything has two sides, the cell phone also has many disadvantages. To begin with, it's expensive to buy and costly to pay the hills, esp. that of global rvice. To make matters wor, it's also easy to lo and costly to get it repaired. Worst of all,it's not as clear as a family telephone and sometimes the number dialed is often not available. Last but not least, it's alleged the microwaves in it might do harm to people's health.
In my opinion,with its expens greatly reduced after China's entry into the WTO, it will face an ever brighter future in its development. Someday most of them will be developed into new Intemet-enabled mobile phones, which will be as uful as pocket comp uters. And I believe its advantages will not only offt its disadvantages, but also far outweigh them.
Now it is the information society,so a mobile phone is one of the fastest information communication tools.On the one hand,they can contact their parents anytime,especially where dealing with an emergency and in great need of the adults.On the other hand,it is a fashion to be equipped with a cell phone.What's more,students can relax themlves by playing mobile phone games.
However,students should u cell phones in a proper way.sometimes,middle school students are too small to prevent themlves from misusing cell phone.For example,students tend to waste lots of time to play cell phone games and nding messages,particularly in class.
As far as I am concerned,it is reasonable for middle school students to follow the fashion.After all,cell phones may bring lot of convenience.Yet since the major task of students is study,it is advisable that they should focus on the teachers and textbooks in class and anyone using his or her cell phones in class should be punished.
Nowadays,some people prefer to speak chine mixed with web language And some peoplr even speak with english,which is considered to be a fashion.Our class have a discussion about it.
About 40 percent of the students think it is ridiculous.In the first place,it is uless in helping people communicate with others or learn english,In the cond place,it will ruin the purity and pormality of chine language.However,60percent students of our class are fond of the web language.They think it is helpful inexpressing themlves.What's more,it may make the language mpre intererting.
As far as i am concerned,i believe the passive aspects outweigh the positive one.i think it is not a good habit to u the web language mixed with oral talking.
WeChat is an application that is almost the same as Whatsapp, but in WeChat, you can add people without even knowing their number. You can also add people from other countries.
First, download the application in your mobile.
Create an account putting your phone number and all the things that they ask you to put.
Then, they will as you if you want to add people that are in your phone-book.
If you want to add people from other place, put configuration and wait for some time.
Wait until it gets scanned.
Shake your phone. You might be wondering why. Well, when someone shakes their phone, and someone el shakes theirs at the same time, then tho two will be connected.
If you wish, you can nd them a friend request and continue chatting!
As the development of high technology, nowadays, people have access to all kinds of new products, the high technology products bring convenience to people’s life It is natural that every adult has a cell phone, but for some students who are belong college, they are not admitted to u cell phone, the reason is that they need to focus on study, cell phone will make them distract At first, students may be addicted to playing cell phone, becau they are curious about new things
Normally I will be very happy and excited when I get the lucky money. And all of a sudden, the problem es that how to make full u of them. I think it is highly determined by how much it is. For example, if the number is around 500, it is wi to buy some books that I would like to read to boarden my horizons. When the number reaches 2000, travelling could be a better choice, becau what we acquires in an education trip is far more impressive than books and documentary. Let's imagine in a rich family the lucky money can be up to 100000. From my point of view, investment is of great necessity, which is able to resist the currency inflation.
Dear Editor，Nowadays mobile phones are becoming more and more popular among the middle school students. Some students think that it is easy to u them to keep in touch with parents and classmates.Also，they can be ud to listen to music or take photos. But others think that we don't need to talk with parents and classmates with mobile phones，becau we meet them every day. And mobile phones may influence our study.In my opinion，it's not wrong to follow the fashion，but the most important thing is how to u the mobile phone in a right way.
Internet may have been one of the most influential but disputable existences in the world,ever since its first appearance in the late 1960s.Internet has accelerated the world’s development with an incredible speed; nevertheless,it has brought this world many burdens.Nowadays,nobody can imagine what the world will be without this double-edged sword.
In my opinion,the most prominent contribution Internet has made to the world is,to offer every one of us such a convenient access to the vast outside information-bad society.With appropriate u of Internet,the distances between people of different nations and countries are shortened.As long as you have a computer with network,you can easily get all kinds of information you need or the latest news from Internet,moreover,you can contact private friends or business companions all at your disposal via Internet.A coin has its two sides,and Internet is no exception to a coin.While bringing the world great convenience,Internet also gives out many negative effects,such as some porn websites,addiction in online games and so on.Especially the young people,with less lf-restraint,if misled,will be likely to indulge themlves in the harmful parts of Internet.As a result,many of them lost their interests in study and eventually become,in a manner,uneducated people.Such examples are not rare in reports.
Given the above arguments,I honestly hope we can make good and full u of Internet,this marvelous fruitful creation of mankind.Although it’s a double-edged sword,with correct lection and decision,Internet has contributed a lot to the whole society and it will go on in this way.
When I first t my eyes on a father and his daughter, I heard the father ask about his daughter's school life. To my surpri, the girl told his father to read her blog so that he can get what he wants. Now, the Internet has been playing an increasingly important role in our day-to-day life. It has influenced us a lot, especially on our interpersonal communication.
For one thing, the Internet makes the interpersonal communication more convenient. We can contact with each other no matter when and where. The Internet makes full u of time and space. What’s more, we can also share our daily life and knowledge through QQ, MSN, and blog with others. For another thing, the Internet speeds up our interpersonal communication. We can save time to do our work. However, the Internet also brings about many problems, such as safety problems, cheating and so on. Many people spend too much time on the Internet, and they don't have time to interact with person in real life, which result in the abnce of ability in communication in reality.
It has both advantages and disadvantages to interact through the Internet. We can get to the problem in our work and study. Last but not lest, we have to talk with people and develop our ability to communicate in reality.
Therapid development of the Internet in China has brought us great convenience in our daily life and work. We can nd e-mail or even talk to our friends or parents via the Net. We can get whatever we need on line. So some people think we can learn all we need on the Internet.
But I do not agree with this opinion, becau sometimes I find many students play the computer games, or talk about love affairs through the Net, which makes them fall behind others in study. In my opinion, the Internet should be a good tool for us to communicate with others rather than an invention for fun. What’s more, it will do harm to us instead of good if we spend too much time looking at a computer.
In summary, it would be very difficult to learn if you don't have a teacher. Also you should pay attention to the importance of working together in a class.So I hope every student values this great invention and makes good u of it.
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 uful 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 lifeThe answers to this question are diver.
Some people think that network is good for their everyday life, for it caters to their inclination. They brow 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 arch 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. Becau 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 advertiments 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 uful 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 clor and clor to you.
