With the increasing popularity of computers and calculators, student literacy is decreasing dramatically. What are the positive and negative effects the progress of science and technology has brought about?
Model Answer:
It has been widely noted that, with the growing use of computers and calculators both in the classroom and in the home, the level of literacy and mathematical ability of students is dropping. This raises serious doubts about the value of the progress of science and technology. Here I will discuss the pros and cons of this question.
First of all, advances in science and technology have certainly brought about many benefits for mankind. They have made our lives more comfortable and healthier. In addition, they have eased the burden of work for most people and provided them with more leisure opportunities, while at the same time increasing productivity dramatically.
Nevertheless, it cannot be denied that technology has some negative side-effects. As mentioned above, with computers which check spelling, grammar and calculation for them, students have little incentive to learn how to do these things for themselves. Also, the availability of TV programs and videos encourages an unhealthy, sedentary lifestyle.
Another aspect of this issue is that technology may be good or bad, depending on how we use it. For instance, dynamite may be used to make road construction easier, or it may be used to kill people. Again, nuclear reactors can supply huge amounts of cheap electricity, but if they are carelessly handled they can cause devastating pollution.
We can conclude that the progress of science and technology has both positive and negative effects. What we must do is to make sure that the positive ones are encouraged and the negative ones are eliminated as far as possible. Among other things, this means that students are warned not to let computers and calculators do all their work for them.
Some people say that computers have made life easier and more convenient. Other people say that computers have made life more complex and stressful.
What is your opinion? Use specific reasons and examples to support your answer.
Model Answer:
Some people say that the invention of computers is one of the greatest humankind's inventions. However, other people think that computers make their life more stressful. I agree with those people who think that computers brought many benefits and play a very important role in our modern life.
First of all, every company nowadays uses a computer to store its data and make different kinds of operations. It is very difficult to imagine life without computers. A company would have to store millions of papers and documents. Moreover, a customer would have to wait hours to check his balance or get a piece of information about his transactions at his bank, while an employee was looking trough those papers. Another important aspect of this is that people are able to type all their information, make corrections, print or send documents using computers. It makes life much easier. One can spend the rest of the time watching TV with his family or working on something new.
We use computers every day sometimes even not knowing it. When we go to a store and use our credit cards many computers process our information and perform transactions. When we need to get some cash we use money access machines that are computerized too.
Second of all, computers provided a great means of communication - the Internet. I think it is the easiest and cheapest way to get in touch with relatives, friends, business colleagues, etc. Nowadays the world becomes smaller and smaller. When I was a little girl, I could not imagine that it would be possible to communicate with people from all around the world in so easy way. A person can get latest news, become friends with someone from another country, find his old friends, ask for a piece of advice, etc.
Finally, in addition to these practical benefits people can shop without leaving their house. They just use an Internet access, a computer and their cards to make a payment. It is kind of difficult to imagine that a few years ago people had to spend their time in lines buying tickets. Now, a person can choose a destination, company, date and time and get tickets delivered to his door. I think it is amazing.
To sum up, I believe that computers made our lives easier. They change our attitude towards life. I think with the invention of computers people became closer and friendlier.
I’m writing in response to the advertisement you placed in Shanghai Daily for the position of overseas mechanical engineer on Mon. .
I would like to apply for this post. I graduated with a Master’s degree in Machine-Building and Electronics Industries in Tsinghua University in 1999 and began my career in Zhongshan ABB Company as a young mechanical engineer. In 20XX, I was promoted to be the chief engineer, taking charge of the projects in Southeast Asia. I have been seeking for chances overseas in my majored domain in the hope that I can develop my potential further.
If possible, I would like to choose a mechanical company with good reputation located in Chicago. I would also prefer small private companies which allow me to enjoy a larger space of promotion.
The reason I made the decision above is that my husband has recently been relocated to Chicago by his company and I am, therefore, seeking a position in the same area in Chicago.
I have enclosed my resume that outlines in detail my qualifications and experience as well as an open letter of recommendation from my former employer.
Please give me a feedback at your earliest convenience if my qualifications meet your requirements.
I look forward to hearing from you soon.
Over the past century, science and technology has been developing unprecedentedly and changing every aspect of people's lives. In my point of view, technology brings about higher efficiency and greater convenience,even though it causes confusion and disorder under some circumstances.
The benefits of modern technologies are multiple. Automation is widely used on the assembly line, setting free millions of people from the arduous and repetitive to the widespread use of the Internet, people have easier access to information than ever before. Instead of going to the library to consult reference books,they can acquire any information they want via the Internet. Moreover,emails and mobile phones enable people to stay in touch more conveniently and efficiently, compared with the old days when they had to go to the post office or visit others in person.
Despite the above-mentioned benefits,we cannot deny the fact that technology may lead to complexity and inconvenience in some cases. For instance,some old people find it difficult to use public facilities equipped with electronic-devices. However, this issue can be addressed with clear instructions provided. Another example is cyber fraud,which is difficult to prevent as the false information can spread very fast on the who get deceived may complain that the virtual space generates more crimes.
Overall,there is no denying that some problems and troubles may occur When various new technologies are applied to people's lives. However, returning to a simple life without technology is not a solution and I believe a better future of mankind lies with the further progress of science and technology.

With the development of cities, more and more new buildings are appearing in the city. Some people claim that the government should ensure all the new buildings should be built in traditional styles. For me, I do not agree with this suggestion.
Undoubtedly, the old buildings can reflect our traditional culture and should be protected and built. They are the houses where the ancient people lived. By appreciating these old buildings, we can have a better understanding of our ancient culture and history.
However, I do not agree that all the new buildings should be built in traditional styles. First of all, a city’s culture identity consists of the past culture and the modern culture. While past culture can be represented by the traditional buildings, modern culture should be reflected by modern buildings. If all the new buildings are built in traditional styles, the modern culture may be lost in the city. Secondly, the style of the new building should be decided by a lot of factors such as location, function, and so on. For instance, it is impossible for us to build a modern shopping mall into traditional style, because there are a lot of famous brands inside. Thirdly, modern buildings can accommodate more people than traditional buildings, which can meet the increasing population.
Therefore, I agree that we should build some old buildings, but we should not build all the buildings into traditional styles. We should consider a lot of aspects before we make the final decision.
The charts compare the sources of electricity in Australia and France in the years 1980 and 20_. During these years electricity production almost doubled, rising from 100 units to 170 in Australia, and from 90 to 180 units in France.
In 1980 Australia used coal as the main electricity source (50 units) and the remainder was produced from natural gas, hydro power (each producing 20 units) and oil (which produced only 10 units). By 20_, coal had become the fuel for more than 75% of electricity produced and only hydro power continued to be another significant source supplying approximately 20%.
In contrast, France used coal as a source for only 25 units of electricity in 1980, which was matched by natural gas. The remaining 40 units were produced largely from oil and nuclear power, with hydro power contributing only 5 units. But by 20_ nuclear power, which was not used at all in Australia, had developed into the main source, producing almost 75% of electricity, at 126 units, while coal and oil together produced only 50 units. Other sources were no longer significant.
Overall, it is clear that by 20_ these two countries relied on different principal fuel sources: Australia relied on coal and France on nuclear power.
