With the developement of my hometown in the past few years, the population is expanding very fast. The city is expiriencing not only a higher birthrate than ever, but also waves of immigration. The streets in the city are crowed or even jamed during the rush hours. If I could change one thing about my hometown, I would develope an advanced public traffic system.
In order to hold such an exploding population, the city has extended miles by miles without much plan. It is common for people to travel from the southmost part to the northmost part of the city to go to work everyday. They have to spend three hours or more on the way they go to work and come home. Eight hours’ work is a heavy burden, while people have to spend hours before and after the work. A subway running through or around the city can solve the problem. People could live further away from the downtown without worrying about spending too much time on the way.
Some people buy their own car or take a taxi to work everyday. It’s really expensive for most of the people in the city. They can’t afford paying so much on traffic fares. Many civil engineering experts advocate that sharing a public traffic system is the most efficient way. People could reduce their fares a lot by using the public traffic system, and they can spend the money on some other things.
Even there are more and more people who can afford buying a car or taking taxi everyday, It is still suggested to using the public traffic system. Because the road developement can never keep up with the demand of the increasing cars, the cars may jam on the roads during rush hours. Usually, the speed of the car in that time is no higher than a bycicle! And pollution is another concern. So many private cars running in the city will bring us an environmental problem. On the other hand, the pollution from the public traffic system is much lighter. All in all, an advanced public traffic system time efficient, cost efficient, and pollution preventing. This is the trend of advanced cities.(Essay ID: 256. This is a 5 point essay)
Nowadays, wherever we turn our gaze, we can see different types of food that are easier to prepare. For instance, we can buy frozen foods in a supermarket and just prepare it in a couple of minutes, whereas before it could have taken us maybe hours to prepare this kind of meals. I would accept that this so-called improvement has changed our lives, but I believe that there are some drawbacks as well.说现象，提观点，两面派观点，认为有好处有坏处。
It is true that these kinds of food do not involve hard work to prepare, but food that is easy to prepare generally has some artificial ingredients
preservatives防腐作剂料 or artificial flavorings调材味料 mixed in it that makes it "easy-to-cook". If we take time to read the ingredients, we would definitely come across words like料. It was just a couple of days ago that I came across a newspaper article which stated that someone was poisoned because he ate this type of food. He was hospitalized for almost a month.方便的食物中有不利健康的添加剂
Not having to cook has also taken the fun out of cooking. Cooking is an art, but in today’s world, this is no more true. People are so busy with their work that they just rely on this simple foods. The invention and production of this foods have made people lazy not only for cooking but also for a well family get-together. It was not like former times when families would sit together and eat freshly baked food. Instead, they are getting these artificial things with minimal nutrients营养 in them.没有做饭的过程也带走了做饭的乐趣
Cooking in the yesteryears was much better than today’s. People would spend more time in the kitchen, preparing the food in the way that they liked it. This brought families closer together and also contributed to the high quality and nutrition of the food. Granted, people are busier nowadays and do not have as much time as they did in the past, but I believe that people have forgotten the importance of healthy, fresh food and of the time a family spends together preparing the food. So, I would say that having food that is easy to prepare has had many disadvantages
There are two main channels for people to learn knowledge –from books and from experience.提出两种情况
Generally, knowledge gained from books is theoretical, that gained from experience is practical. It is difficult to answer which is more important to we people. It depends on the phases and events of our learning. Knowledge learned from books is instructive教育性的, which perhaps cannot learn directly from experience. We often hear thunders雷
声 and see lightning in the sky, and we can easily find that lightning will be seen sooner than sound will be heard. According to our experience alone, we cannot tell why it had happened. But when we learn some physics in textbooks, we will find the answer clearly that because light travels faster than sound does, it takes less time for light to travel the same distance than for sound. Therefore, book knowledge can inform us some useful theories that can give us general ideas and help us understand the real phenomenon better.书本知识有时比实践知识更instructive，例子举得很好 In turn反之, practice knowledge check out the theories gained from books. There is an old Chinese saying that practice is the only criterion of inspecting the truth. So not all knowledge from books is credible, even false. When Aristotle wrote in his transcripts that the earth is the center of our planets, no one doubts this for centuries. However, when Galileo read about it, he did not suspect it at first, but when he made some observation and research, he found it is not the truth. Then comes the new theory—Sun center theory
In our daily life, we can learn much information from practice. To learn swimming, it is useless to be absorbed in reading skills written in books. Only when you learn it in a swimming pool, can you make it. There are still a lot of things you must learn from your own experience, such as driving a car, riding a bicycle, operating a machine. And the most important is that it is often easier learn knowledge from practice than from books. As far as the average people are concerned, it is natural to learn from experience. Primitive原始
学的 people learned skills hand by hand which is the way they were handed down from one generation to another. Modern people also learn things in practice. In workshops, leading workers teach apprentices
徒 carefully; in activity clubs, teachers teach youngsters to be familiar with their hobbies. It is obvious that all of things considered knowledge gained from practice is more close and direct than from the books.在有些知识上面，实践来得更加直接易懂
Therefore, two kinds of knowledge has importance. For research people, knowledge from books is more important, while for our average people, knowledge from practice is more important. As students, we must first learn knowledge from books well, and at the same time we must have the good sense to tell from what is right and what is wrong.总结，说明两种知识都重要，最重要的是要学会分辨
If a large factory is going to be built near your community, is it good or bad? It’s a quite difficult question to answer. Because there are many aspects to take into your consideration, the advantages and the disadvantages. Let’s talk about that.
First, a large factory, especially a large chemical factory is quite harmful to our environment when it is built near our community. It will affect our daily life a lot. All the chemical factories will produce a lot of waste and most of the wastes are harmful to the environment, including poisonous gas and liquid. Some of them can not be entirely broken down. If they are released into the air or the river, it will affect our health. And also the factory may produce a lot of noise. The environment we want to live in is a quiet and peaceful one, so the noise will be quite boring. And yes, noise also affects our health.Still one thing, a factory can be very dangerous. Because a fire or a explosion may break out in the factory. If it’s very near our home, it’s quite dangerous.
But in other hand , a factory may be a good news to us. It can provide more jobs for us, especially for the young people in our community. Since the factory is near, it’s so convenient to go to work.. and the factory will get more chances to our area. It will help to develop our area. So if the factory can bring us a lot of chances, we will agree to build one. But the most important things are:
1. Build the factory in a safe distance from our community, not too near.
2. Make sure that the factory can deal with the waste properly. Do not release the poisonous gas
into the air, and not release the waste water into the river nearby.
3. Make sure the security guard in the factory works very well.
