ESSAY
Nowadays, we have many conveniences in our society which have been brought about through technology and science. However, these same advancements in technology and science have caused some very dangerous problems. These problems will not go away easily because people do not want to give up the conveniences of a modern lifestyle. The most critical problems which should be dealt with immediately are those of pollution.
Pollution caused by chemicals is a very serious problem because it causes the loss of the ozone layer. Without our ozone, not only we ourselves but all plant and animal life are exposed to dangerous rays from the sun. Aerosol cans emit chemicals which break down our ozone layer. Refrigeration and air-conditioning systems and cars also have dangerous emissions.
Perhaps the most serious threat to the planet is the warming of the earth’s atmosphere, primarily through carbon dioxide emissions. Many scientists think that the warming could be sufficient to melt the polar ice caps, thus raising the sea levels. This would mean that many parts of the world would be submerged below sea level.
There are other problems caused by pollution. Factories which make our modern conveniences emit poisonous gases into the air we breathe. The chemicals we use for cleaning and wastes from factories go into our water systems and pollute the water we drink and the fish we eat. They also kill much of the wildlife we depend on for food. Some of the pesticides we have sprayed on our crops have been found to be dangerous. This kind of pollution may stay in the ground for a very long period of time.
In conclusion, the problems created by pollution are growing daily. Because people do not want to change their lifestyles, we must invent a way to neutralize the pollutants we are putting into our environment. People need to be educated so they will stop damaging the planet. Furthermore, governments must take action to prevent individuals and companies from harming their environment.

Technology refers to skills, knowledge, and techniques that human beings use in their daily life and work. As everybody may find, technology develops day by day. How does the development of technology affect our life? Many people hold the opinion that it is due to the development of technology that human beings have access to the comfortable modern life. On the other hand, a number of people are always aware of all kinds of destructive influence of the technological development on us. As far as I am concerned, the development of technology do far more good than harm to people’s happiness.
No one will deny that technology helps solve numerous problems and thus make life much better. Firstly, the development of technology enables human beings to find better solutions in industry and in other working fields. With computer technology, we can do work more efficiently and more quickly than ever before, thus less cost and better quality. For example, car industry gain enormous increase recently on account of the great change in assembling as a consequence of the wide spread use of robots. To the well known and familiar example of car industry, many more examples may be easily found,such as the clothing industry and glass industry.
People also benefit a lot in their daily life as technology develops. With cloning technology, we are able to prevent many precious animals and plants from being extinct, so that it is more likely that we keep the ecological balance and we may have more harmonious relationship with nature. With modern drugs and advanced surgical techniques, we have the capability of curing many dangerous diseases and safeguard people’s health, so people enjoy a longer and healthier life. With modern jet planes, traveling to different parts of the world takes only few hours or days instead of weeks and even months.
Considerable though the advantages that the development of technology enjoys are, people should never ignore the disadvantages that the development of technology brings along. The computer makes people relax a great deal, but too much time spent on net games also deprives people of the chance to contact with each other. The airplane makes the world smaller; however, who is going to deny that thousands of people die in plane crash accidents every year? The machine makes work easier, but they give out poisonous gases which expose us to lung diseases and even cancers.
In conclusion, I think although advances in technology may do some harm to people’s life to some degree, most impacts exerted by the forward pace of technology are desirable and beneficial. We should take measures to guide the direction of the development of technology and prevent all kinds of improper use of technology so that we can enjoy more conveniences in both work and in daily life brought by the ever improving technology.

It is not rare to see many students dozing off or doing other things while the professor is trying his best explaining a theory. Most people claim that this phenomenon results from the severe school attendance rule and suggest that students should be given more right to decide which class to attend according to their own interest and their judgment of the value of the class. This idea is strongly opposed by numerous people who hold the opinion that it is the fault of the students that leads to the current problem. They stand on the ground that students do not really know what they are particularly suitable to make research on and what kind of class is remarkably valuable. Consequently they think highly of the rule that students should attend all the classes. As far as I am concerned, strict school attendance really benefits the students in not only acquiring knowledge but also their social skills.
結(jié)尾:
Students are the future masters of the world. Only when they have accumulated abundant knowledge and tactful social skills can they be confident to say they are fully prepared to manage the world. Strictly required school attendance is one of the best approaches to helping students accomplish the two. While at the same time schools should also take measures to draw the attention from all students and improve the quality of teaches’ lectures to be appealing to all students.
