Is this sentence correct in its expression? The sentence is: One primary product, cars, has been applied to transportation with 200 km/h over eight decades, is being required to extend its current limits for higher speed. What am I trying to explain is the cars have already been used for over 80 years in transportation, and nowadays scientists are attempting to break its current speed limits and make them faster. However, I am not sure whether the above sentence fulfills its mission to convey such kind of information. The clause 'has been ...' here is to act as an additional explanation to the cars, which aims to state their past and current application situation; the main part of the overall sentence is cars are being required to extend its limits. But I always get a feeling like there is a conflict between the "has been" and "is being" from a perspective of grammar. Is this sentence right or wrong? If it is incorrect, how should I polish it? Thanks in advance for your answers.

Does the phrase "leave school" mean "graduate from schools" or "drop out of school" to some extent? Someone told me her English teacher said that the "leave school" represents graduate from school (with completing all the required courses); however, the explanation from wiki says: Dropping out means leaving a school, college, university or group for practical reasons, necessities, or disillusionment with the system from which the individual in question leaves. Now I am a little bit uncertain about the exact meaning of the leaving school and if possible, could you guys explain that according to your knowledge?

In many parts of the world, children and teenagers are committing more crimes, what are the causes? Topic: In many parts of the world, children and teenagers are committing more crimes, what are the causes? How to solve this problem? ------------------------------------------------------------------------------------------------------- My essay: In recent few years, there is increasing trend for the crime rates of youth in some regions, which trigger great concern by the public. This essay will discuss the reasons for this problem and provide some possible solutions. First, there is a close connection between those underage criminals and their family education. The fast-paced lifestyles often make parents forget them to fulfill their responsibilities for their children’s education. The children who lack parental guidance usually have an incorrect understanding of their own faults and will pose a huge hazard to their future development. Besides, the unfair treatment comes from teachers is another reason which is involved in this issue. It is a common thing for some teachers to favor those students who often achieve high scores in tests. For the rest of students, their feelings and emotions are usually been ignored by their teachers. This inequity aggravates their discontent and finally leads more youth into criminal behavior. In addition, parts of the media should be responsible for this problem. The frequent violent and horrible scenes have a great negative impact on the growth of children and sometimes they will imitate the atrocities unconsciously. In order to reverse this situation, there are several possible approaches. Firstly, even though most parents are busy with their work, they should manage to put aside some time to keep their children company and strengthen their children’s education. Secondly, schools should set up regulations to minimize the inequity. The assessments of children should be included in the educational system as one factor to assess the performance of teachers. Lastly, the government should restrict the frequency of violent scenes and provide a healthy environment for children. Only by those approaches can we reduce the risk of juvenile delinquency to the greatest extent.

Many young people leave school with a negative attitude. Why does this happen? Topic: Many young people leave school with a negative attitude. Why does this happen? What do you think can encourage young people to have a positive attitude? ----------------------------------------------------------------------------------------------------------------- My essay: In China, not all the students can complete their studies successfully. Most of them drop out of school for various reasons and often leave with negative attitudes. Although Chinese government emphasizes the importance of education all the time, the dropout rates are still hovering at a high level. There are a couple of causes involved in this issue. First and foremost, a misunderstanding of education can be the major cause which may induce them to break off their studies. The real role of education is to teach students how to think about problems and find solutions. However, many students are more likely to see it as career training. When they find it has little value for their job hunting, they are disappointed and refuse to continue their studies for thinking it is a waste of time. In addition to this, the way how their teachers treat them is another reason which helps creating those negative thoughts. It is a common thing for some teachers to favor those students who often achieve high scores in tests. For the rest of students, their feelings and emotions are usually been ignored by their teachers. This unfair treatment aggravates their grievance and dissatisfaction with no doubt and finally determines them to drop out of school without hesitation. In order to solve the problem, several measures need to be carried out. Firstly, it is imperative for students to set up a correct understanding towards education. They should bear in mind that the main idea of education is to inspire their potentialities rather than training them to learn some special skills. Besides, finding a way to eliminate the inequity can reduce the dropout rates in further. If we can achieve the above two, eradicating this issue is just a matter of time.

Should animals be used in testing new drugs or other products? Topic: Should animals be used in testing new drugs or other products? ----------------------------------------------------------------------------------------------------------- My essay: Animal testing has become a routine when developing a new drug or products. However, the humanity presents this issue in stark form to people that whether we should use them for test or not. Some people argue that every living creature on this planet has an equal right to survive and we cannot treat them as inferiors or think their life worthless. Personally speaking, I do not completely agree with that. Firstly, I have to admit that animals have no responsibilities to pay for human diseases or safety problems with their lives. We rarely take human experimentation into consideration when testing new drugs or medical procedures because it is inhumanity to enforce people to suffer the pain. Besides, people can express their feelings by words or screaming when they are in pain, while the animals can only keep silent. So testing with animals is a better way to alleviate the sense of guilt of humans. But it is an inevitable choice for humans because in current situation there is no alternative method to test. No one will accept a medication that is without safety tests for fear of causing side-effects or setting their lives under risk. And if we should feel guilty for testing them, should we feel guilty too for eating them at the same time? Eating animals benefits only one person, but experimenting on them benefits all mankind. What is the verdict on the issue? There is no certain answer to this question because animal testing is a two-way street. In the light of the present situation, although it is very cruel, it’s an efficient means to push forward technology and science innovation.

Some people think the media should not report details of crimes to the public Topic:Some people think the media should not report details of crimes to the public. To what extent do you agree or disagree? --------------------------------------------------------------------------------------------- My essay: Rarely a day goes by that the media does not report an incident of violent crime such as theft, muggings or murder. These are reported via broadcast, digital media (internet website or social site) and print and the reporting is often in excruciating detail. For fear of causing negative effects on the public, some people argue that the government should demand the mass media to omit the relevant details of crimes. Speaking from me, I cannot agree with it more. From my point of view, there are a couple of reasons to support this view. First, a large number of such news has filled our daily life. Those exhaustive new reports often have a little help to build people’s precaution consciousness but only to scare them. People who are surrounded by all kinds of criminal news in a long term are more likely to lose the sense of security. The loss of sense of security will incur the distrust between strangers and strengthen the social alienation in further. In addition to this, the release of criminal details will deprive the victims of dignity and privacy, undoubtedly. Today many mass media are often regardless of the feelings of victims and add relevant details as a selling point in order to jack up their newspaper circulations or television ratings. This behavior will remind the victim that what the criminals have done to them and cause them another hurt. In sum, some restrictions should be carried out to improve the way of reporting criminal news. Those restrictions will not prevent reporting of violent crime but make it not so prominent and it is also a good way to protect the victims from further mental damage.
