cars and life Individual vehicles have been employed for over hundreds of years, and the number of them keeps rising dramatically. The increasing growth of the number of private cars leads to severe problems that individuals and society should be concerned by. It is undeniable that cars bring in a lot of conveniences for people’s life, but what suffer more are the harmful consequences accompanied with the over relying on private cars. It should be admitted that air pollution is mostly due to the increase of private cars. Not only carbon dioxide, also particulate matter are both emitted by vehicles. They are the main courses of bad air quantity. Another problem that caused by private cars is traffic congestion, especially in those cities which excessive private cars are employed in rush hours. What’s more, large numbers of victims in the accidents is one more aspect should be considered. As all we can see from newspapers and news reports, the number of victims in the car accidents has been increasing since the excessive use of private cars, even if some countries issued a variety of measures and laws to transportation. The question of how to solve the problems mentioned above is debated. Some people believe that petrol cars should be replaced by cleaner cars, such as electronic cars, will contribute to preventing the unoptimistic condition from being worse. But I insist that the most effective measure is the reduction of the number of private cars, and to encourage more people to pursue public transportations. Although many disadvantages come up with over use of private cars, the convenience and other benefits cannot be ignored. What should be thought about more is to find a balance between cars and life.

Languages Languages came up with human beings since we existed. Some languages vanished in every year, and it is a phenomenon that individuals and societies should concern about. I believe it is not simply to say that the varnish of several languages is important or not. Indeed, there are a few inconveniences appeared due to the used of different languages in different countries and areas. The most significantly difficult thing is the barriers that between two or more countries’ people who just know and speak their own languages. Some conflict arose as a result of the understanding during communications between different languages speakers. People need to spend a lot of time on studying a foreign language if they want to learn about another culture. Also, it is less efficient when people have conversations with different languages speakers. More different languages bring in more misunderstandings, sometimes. But as like the beginning of this article said, languages have accompanied with human beings for over thousands of years. In some instances, the history of human is the history of languages, and the evolution of humanity is the evolution of languages. Just like every country has its own cultural traditions, it also has its own unique language or even more than one language. If the language of a country is extinct, then the history and culture traditions of this country are died out to a certain extent. Because its next generations will have no chance to know about their homeland’s cultural traditions and history through their own language. Overall, language is an essential element in human’s history and daily lives that cannot be ignored. Over and more than that, language is a great treasure that has been inherited from generations to generations. It contained a lot of things, such as culture, history, etc. We must preserve each language as possible as we can.

looking forward someone's correction. The two graphs above illustrate the changes of an island before and after the rebuilt with a lot of tourist buildings and items. It is clear that before the development, the island is 260 meters long which has some trees on the west and east side of it. Furthermore, there is a little beach on the west edge of the island. After construction, the beach and trees are reserved. Some accommodations are built in the center and around the trees on the west side of the island. The west part of accommodations is linked by a footpath with the beach, where a swimming area is developed. Between the two parts of accommodations is a reception building surrounded by vehicle track. In the north and the south of the reception building is a restaurant and a pier, that was connected by vehicle track respectively. And people can play sailing near by the pier. Overall, a variety of commercial infrastructures have been built on the island, but the size of it has remained.

government, violence, media, crimes topic The government should control the amount of violence in films and on television in order to decrease the violent crimes in society. To what extent do you agree or disagree with this issue? essay: Youths violence is a problem that many people blame the media, which they believe should be supervised by the government. I disagree with this idea and believe instead that society itself should fix this problem. In today's world, young people are influenced by many things, like television, films, and websites. It is thus unreasonable to accuse only movies of increasing violence. In other words, today's youth come across all human behaviours equally, such as violence and kindness and greed generosity. They can witness these things in one news broadcast just as much as they can in an action movie. Thus, blaming the entertainment industry is not only unfair, it is also wrong because it ignores the root causes of these behaviors. To suggest that government should control this, then, is to taking responsibility for ourselves. Indeed, a government should not act as parents to its inhabitants. It exists to ensure a society can thrive, not to tell people what to do. On the other hand, parents can and must control what their children see online, in movie, or any other source. Consequently, parents must decide whether they want their children to watch a horror movie; it is not a government's job to ban a studio from making it. Once a government controls one sphere, it will be free to act in all areas of our lives because negative influences are everywhere and have always been so. Not only will government actions not stop violence, they will likely increase it as people fight for their freedoms. In conclusion, violence can be triggered by many things, including but not limited to media influence. Governments should therefore not be allowed to restrict what entertainment companies produce because they will then have to spread their control to all areas of society.

Friends 1. What do you usually do with your friends? How long have you known your best friend? I like outdoor activities, so when I have free time, I usually play ballgames with my friends. We have known each other for such a long time, two or three years, I think. Yesterday, we have a short conversation and made an appointment that we will go jogging next weekend. 5. Which do you think is better, to have many friends or just a few close friends? In my opinion, I believe that a close friend is extremely better than many friends that you are not so familiar with.

I would say that family is the most important thing in my life. And also friendships are also indispensable during our daily lives. At present I am spending more time with my family because most of my friends are working, so am I. We don’t have much free time to hang out or play outdoor games as before. Even though, playing with friends is a good way for relaxing and we had lots of interesting memories. In recent years, I realized that I family can give me the sense of belonging. I would say, the persons who are responsible, outgoing, and have a little sense of humor will be popular with their friends.

teachers Do you (or, did you) have a favourite teacher? Why do you like him/her? How does (or did) this teacher help you? Of course, I did. That was about ten years ago, I met my biological teacher. He was an active, patient, and responsible man. He had well prepared almost every class. And I could learn a lot of knowledge from him. Furthermore, he was willing to help individual students with their studies. If anyone had a confuse about something or struggled in any theory, he would give him or her advises patiently. Do you think you could be a teacher? Would you like to be a teacher? It is not simply to say a yes or no. I am not a teaching in primary school or high school, but I may be a teacher in some instances. For example, when parents are teaching their children, they are teachers. And I think teacher is a good occupation for me, especially the primary school teacher because they can teach teenagers lots of knowledge that they are interested, besides, they have the chance and duty to educate children to be a valuable and responsible individual.
