Sample 2
Writing 1
Almost everyday we see something on TV about the new exciting developments in science and technology. The latest one, perhaps, is cloning. News has come from England that researchers have succeeded in creating a lamb from a cell in an adult ewe, a young lamb which is in essence her mother’s identical twin. Although people cheer the embryonic cloning as a breakthrough in reproductive technology, they also feel a danger: if scientists can clone sheep, why they cannot clone people? As I see, the mixed feeling is a mirror of their concern over the development of technology.
No one will deny that the introduction of modern technology has improved the structure of society, and helped man to gain increasing control over his environment. The technology of cloning, for example, opens up many exciting possibilities, from propagating endangered animal species to producing replacement organs for transplant patients. Agriculture stands to benefit as well: dairy farmers could clone their champion cows, making it possible to produce more milk from smaller herds.
Another example of the benefit man gains from technology is the computer. The development of computer technology leads to the creation of robots which provide man with much help in many aspects. For instance, with the aid of robots, the components of a car can be assembled more quickly and more accurately than that done by human hands, thus lower cost of cars and better quality too.
The growing concern over the effect of technology, however, I believe, is not without reason. It is clear that many major problems we are confronted with today are either a direct or indirect consequence of technological development. For example, severe air pollution brought on by the wide application of modern technology in factories has posed a threat to human survival. It not only causes much acid rain but also the loss of the ozone layer in the atmosphere, which will expose human beings directly under the solar ultra-violet rays. To the well-known example of air pollution, two more may be added: the depletion of energy resources and the military space race.
From my point of view, since seeking for better living environment is one of the chief desires of human beings, it is necessary that steps should be called for to guide the direction of technological development and to improve our protection against harmful uses of technology. Among other things, the political system must exert more effective control over technology; better means must be found to anticipate its consequences; and more reliable information about technological developments must be available to people at large, so that a human clone won’t emerge in the future.

Whenever we mention modern technology, people’s opinions always vary differently. Technology refers to the skills, knowledge and technique that human beings use in heir daily life and in production. They have both advantages and disadvantages.
It solves many human problems and makes life much better. For example with computer technology, we can do work more efficiently and more quickly than before. With cloning technology we can prevent many animals and plants from being extinct. With modern drugs and advanced surgical techniques, we have cured many diseases and prolonged life. With modern jet planes, traveling to different parts of the world takes only few hours or days instead of weeks and months. We owe all this to modern technology.
But technology has created a number of new problems. The computer makes life easy, but deprives people of the chance to contact with each other. The airplane makes traveling easy, but exposes people to accidents which have become so numerous and claim many lives daily. The machine makes work easy, but they give out many poisonous gases which expose us to lung diseases, and even cancers.
In conclusion, I think that although advances in technology may seem desirable and favorable, there are also a lot of problems which it introduces into our ways of life.

The need for technology has been with man for a long time. Because of the limited physical strength but they have the need to move around, man has been creating tools to help him to do so easily. For example the problem of transportation has always been a major obstacle. Then cars, trains and airplanes are created to help people to go to move from the place to the place at much more quick speed. People now can send and receive foods and goods from places much further than they used to be able to do so. Modern technology has also been a great help in keeping people healthier, and help them live much longer. For example people can clone a healthier baby or an animal which is going to be extinct. People can enjoy a more comfortable life now with computers, TV and VCR.
On the other hand, modern technology brought pollution which was harmful to people. The world has become a dangerous place to live. Also the modern technology has brought more destructive power to man. A good case in point is nuclear war. In my opinion, I think technology has created new problems for man, and these are problems with a very far away solutions.

Nowdays modern technology develops so quickly. In my point of view, I support technology can solve problems and makes life better. Such as the development of computer. Computer helps human to solve thousands of problems, especially in life. A lot of calculation was so complex. It is impossible to count them if the traditional method is used. We should use a very fast computer in order to solve it. Especially the robots. They like human. Because they can think and do a lot of works we humans can not do. They have heads which are filled with thousands of answers. They have long and clever hands which can do operation in hospitals and do work in factories. They are expensive, but they can contribute to our life.
But modern technology also created many problems such as produce a lot of pollutions. They make us feel dizzy when exposing to them. A lot of cars running on the road create much CO. They seriously effect the earth’s nature condition. You know, the weather became so bad. there are a lot of acid rain.
Writing 5
Modern technology does a lot of goods to our lives, which I can suggest to many examples in every day life.
Morden technology, like since would be very useful in some condition. For example it would be very important for better live and make the life’s things to do easier than before. Like since, it also has harmfulness to man.
There are many people in our citys enjoy the modern technology. They try to make the useful way of using it. Because they find more and more progresses in technology. Computer is example. Cloning is also example.
But some times technology make some problems. In city, mans and womans had to eat dirty water and dirty air. This cause to happen many deseases. This problem become badly enough. They hits technology and trys to protest them against it.
In short I would tell my view. Technology is not good things. It does a lot of goods to our humans. Air pollution is bad! dirty water is bad! Cloning is bad!
