However, we should still considering the risk of second- hand smoke and passive smoker who suffer in share area. According to a study by NSW cancer institute, sidestream smoke which burns off the end of a cigarette may cause more toxical than mainstream smoke a smoker would inhale. Passive smoking can cause premature death in non-smoker. Second-hand smoke and passive smokers are no risk-free level and it is harmful to our bodies. Beside this, smoking in  public should be banned.

It's true that people have freedom to do what they whenever they want and wherever they are. However, other citizens also have  corresponding right to  stay healthy. A recent survey has showed that toxins produced by smoking have a significant negative effect on pregnant woman, Moreover, residents always stay with smokers have an incredible high risk of getting lung cancer as well. Therefor, we should forbid smoking in public to protect public health. In addition, smoking areas are suitable for smokers to enjoy smoking.

Chores is one of the best way to tech children respect for their parents and also help them to be mature. A recent survey showed that there is a strong relation between daily chores and children matureness. Those who help their parents as doing chores are more likely to behave well in a class room. It is true that this might be a burden for them, however this is really important for them to have those mindset to success when they go out  into the world

I agree that public transport should be free in cities. Research seems to indicate free public transport would reduce the number of cars  on  the road  and protect environment,also increase the employment rate. If public transport was free, more people would use it and taking cars off the road. A recent survey showed a public transport system with 20 trains could take 40,000 cars  off the road, the result of free public   transport would be dramatic in combating global warming. what'more, we would need more public transport workers , such as bus and train drivers. so public transport free make  it easier  for people  to get a job. so i believe public transport should be free in cities

（the internet is harmful for children）

The issue of the internet is harmful for children has become a huge concern to the general public. In my point of view the internet would causes a series of problems.
A recent survey showed, children who spend large amount of time glued to a computer risk develiping mental haelth problems such as loneliness, depression and anxiety.
From my experiences, when i use internet for a long time. I always feel dizzy and sick, don't want talk to others, let along the children. Using internet to looking for resources or checking news are good way to enhance knowleges. However，how much time you spend on it.
To conclude, spending to much time on internet is not a good choice
for chirldren's health.

Mobile phones have changed the world of communication. A recent research showed that

I  agree that children are  too  young  to have  a formal job,  but more parents  hold the  view that children should be given jobs to do in the home. From  my experience ,I often help  my mother to do some housework such  as  wash dishes  and wash the  car sometimes , because  all  of  us believe doing housework  not  only helps children  to foster the sense  of responsibility  of their family,  but  also  teaches  them to share work with others and   finish together .  A recent survey showed that having a job  in the home will improve children' s confidence when they achieve some easy items in housework . As far  as  I  am concerned , to improve various abilities which children  need in the future , parents should encourage  their children attend to housework.

Children should be given chores to do in the home. It is a good way to practice children's ability and foster their independence. Research seems to indicate that children who do housework at home are good at addressing problems by themselves. For instance, my sister often gives her son some chores and teaches him how to do it. As a result, her son had taken care of himself in primary school. However, some children who do nothing at home have more time to focus on their study and interests. They might get high marks in their examinations. But most of them are not active and confident. So parents should give children chores to do at home.

I agree the phone is an important invention, but I do not think it is the most vital invention. There are many amazing inventions in the world. Firstly, subways change the way of citizens' daily travel. Besides, it extremely relieves the pressure of the crowded public transport in the big cities. Secondly, the computers have become the necessity in people' life. People need computers no matter at home or at working. Finally, the Internet dramatically change the world. The whole world can be connected by the internet which is the basic reason of globalization. Although  the phone make the commuciations with people more convenient, it is not the most important invention.

It is harmful for children if they put most of their time on Internet. A resent survey showed that the high rate of crime in juveniles meets the violence on the Internet. As a result, they may copy bad plots on the Internet. Some students around me can not judge the virtual world and real life so they may do some anti-society issues. It is true that the Internet may harm for chilren If they pay much attention on that, however If they can control themselves better, children may receive knowledge from the Internet instead of paper books.

I agree that university should support more social courses for students. One of the reason is that social courses are more practical and useful for their further career. Through these curriculums undergraduate can well- prepared for their jobs to accumulate experience. I admit that it is true academic courses also play an important role at university because  it contains the basic knowledge about their field. However, most of these courses can not be utilized in student's job experience.

Also it is a phenomenon that everyone using their telephone everywhere-while they are working, studying or even walking. Still, it is true that the internet is the most important invention nowadays. Because without the Internet, all electronic devices, especially telephones, are unuseful.

We have to admit that the Internet has several advantages.
However, I think the Internet is detrimental to children's eyesight.
Research has shown that nearly 60% of teenagers in China wear glasses due to surfing the Internet for over 2 hours each day.
When I was 12, I began to play Internet games.
After that, my eyesight became worse and worse.
Although the Internet gives children more concience.
I prefer to recommand that as parents, you should control your children's use of the Internet

Smoking in public should be banned.

I admit that sometimes smoking is helpful to release pressure, but smoking in public is harmful to the public health. Research seems to indicate that cancerogrnic smog from cigarettes Is mostly breathed in by the people around the smokers, which Is more dangerous than smoking directly. Smoking in public violates others' interests of keeping health. Besides, it also damages the image of a city. So smoking in public should be banned.

The U.S.A is currently the most powerful country and is the symbol of democracy in the free world. Its constitution states people the right to have guns. From the long history of human beings. We can get the conclusion that the peace would just depend on practical and fair princples and laws. Qin Dynasty took weapons from the hands of people, but the measure could not prevent itself from the revolution of people.

(Statement )High school students should choose their own study subjects by interest.

In my opinion, high-school students should study subjects that they are interested in. I agree that some students would choose their study subjects with their friends instead of interest. According to a recent study by Oxford University, students have more incentive to find further information in a field of study that appeals to them. As a result, students learn a lot of knowledge without textbooks, which is the purpose of education.
