It can be said, social network is gradually occupy important position, affecting not only small human life, especially the young. But it also needs to know how to use social networks scientifically so that it becomes a useful tool in life rather than being turned into its "slave". From then on, leverage and promote the positive benefits that social networking bring, limit and eliminate the negative impact caused by the number of users. Facebook is a great example, let's say it's a place to share useful information, information and sympathy, and be cautious with open relationships that you can easily get with just one click. mouse. I can not imagine how they would bring about "disastrous" surprises ...
A recent study at an American university shows:
Students using FB have less than 20% study results compared to other students.
Outside the classroom, 88% of non-FB students actively participate in extracurricular activities.75% of students using FB do not think that this social network will reduce learning outcomes.
Some of the biggest negative effects that social networks have on children today are:
High self-esteem.
Psychological disorders, including anti-social behavior, paranoia, negative life, excessive drinking.
Frequent dropouts, high risk of stomach pain, insomnia, anxiety, depression.
Poor academic results.

The Internet seems to have become something very familiar to many young people, especially in big cities. But is that familiarity as positive as we think it should be? It's not just one dimension from the bad effects that the press has talked about, such as porn sites, porn chat, nudity, celebrities .... Where, TTN is too lack of orientation to know and see the need to exploit the positive aspects of virtual world ...
Customers in Internet cafes are mostly teenagers. They use the Internet to ...
The most visible thing in all over 20 Internet cafes in many areas of Hanoi where we are is: The vast majority of customers are on the Internet for chatting, most of which use the software. Yahoo! Messenger (YM), the rest use ICQ, AIM and public chat rooms. Perhaps we need policymakers to conduct a large-scale survey to give statistics on how many percent of Vietnamese Internet users use the Internet for entertainment (in which there are many types Leisureless, even toxic), how much to serve the needs of learning, improving knowledge. From the perspective of a normal person, one can notice in Internet cafes, where the majority of school-age customers, reading screens, search the information on the net. Extremely rare. It is hard to imagine that among the TTN manipulation "chat chit" on YM as lightning fast fingers, many people do not know what is web browser. Some know just about accessing some very limited websites.
Girls under the age of 20 are engrossed in a series of "flashing signals" on the invitation screen. P. and T., two 16 year old girls giggling before 6, 7 chat windows have pictures at a restaurant on Lake Dac Di Road, shook their heads as we asked outside the chat never to network. See the website does not. HY, a high school student, also has a computer connected to his home network, but he likes to go out on Nguyen Trai Street because he is more comfortable and does not have to be watched by his mother: "I usually chat with some friends in the streets. Another province ... ". HY was happy to write in his notebook and said: "I will watch this site from home. My mother will not ban!" Computer screen of Đ.P.P (12th class of Quang Trung school) also has some chat windows: "I just started to network for a month now and just to chat. I do not know much because nobody is guided. I do not know English. The network is hard to spread ... ".
Spontaneity, lack of direction and too little efficiency: Beneficial harm?
"Not guided", which is the current status of TTN today for IT in general and the Internet in particular. We often talk about the importance of IT, the need for a global network for integration and development, and even the growing interest of young people in using the Internet is a sign of improved skills. Informatics and Educational Development. But it seems that we are "too trusting" or rather leave behind the self-discovery of the TTN.
In developed and developed countries, the use of computer networks, including the school network and the global Internet, is an integral part of the learning process. The issues are open and up-to-date, requiring students to look up and collect relevant information and knowledge so they can master the lesson and do their homework. That is not to mention the key, specialized hours specific instructions on the use of computers and the Internet to serve the study and research in all areas. The priceless knowledge base from the Internet is always taught by teachers who focus on how to exploit efficiency, direction of use and warn of threats.
In Vietnam, there are almost no plans to educate and orientate the use of computers and the Internet in a fundamental and broad way for students. Courses that are not related to IT are more limited in content and form of teaching, not create the desire to explore, discover more for children. Pham Huy Thong, a teacher at Giang Vo Secondary School, confessed: "We know many middle school students have become acquainted with computers and the Internet at home or through Internet cafes, but these activities are outside the classroom. At school, we can not manage it, but in order to orient the current level II has no program and plan to teach informatics and equipment is very inadequate. Still quite awkward to know how to exploit effectively,
At middle school age, the children are beginning to be eager to learn new technologies. Schools do not teach, they tell each other how to use and of course, learning the useless, the bad is always the easiest. In fact, there are not as many parents as my mother HY keep track of what I do online, but most often have the mentality that kids learn "those" faster than me. The parents we asked all said never or rarely check what their children do with computers and the Internet because "checked also do not know which way" - said Hung, there is High school children high school Vietnam - Germany; Or "they are fascinated with computers is good" - Quynh, a child secondary school Ngo Sy Lien said. They also said that females almost never talked to themselves about what they do, read, or see on the Internet.
Thay Thong shared with us that the Ministry of Education and Training would soon have a comprehensive and appropriate computer training program for each level, as well as educational software, e-books, databases and websites. Having practical contents directly related to science in all subjects so that pupils and students can have their own research and discovery conditions. Without such basic orientations, how much money to equip, how much time children spend on the Internet will be wasted and even "harmless".

Nowaday, traffic problem is the biggest problem that many people care about. In VN, I think the city where have the worst traffic is Ha noi.
The first problem is the traffic jam here. Why? In the rush hours of the day, there're too many people using the road. Last year, in 2013, many bridges was built so it happen less but in order to stop this, a kind of small car should be invented, people should go to works by buses instead of going by motorbikes...
The second one, as you know, the roads in VN is not as big and clean as the roads in the big countries. They're narrow, bumpy and some dirty so it’s really hard for the road users to drive safely. I think we should raise money to make the road in VN better and better.
But everyone knows that Vietnamese people are not respect and don’t follow the traffic rules. That’s the biggest reason for everything. They wear the helmet that not strong enough to keep they safe if the accident may happen, they ride too fast on the small roads… The traffic will never can be improve if they keep doing this.
At the end, I hope the traffic in VN will improve more.

Floods are a natural phenomenon. They cause tremendous havoc to human life and property but are sometimes also a blessing in disguise because they bring alluvial soil which is essential for crops. This is a great benefit compared io the havoc it creates. Floods are naurals calamities nad occur regularly in certain low lying area. The unexpected flood causes great misery. The rush of water demolishes houses and destroys homes. It inundates large areas under cultivation, wrecks public services and makes the life of the surviors miserable. Sometimes man is prepared for it and has learned to take advantage of floods to enrich their soil, trap fish and more logs of woods. Floods, however have always brought out the best in men. Men organise recus and relief activities for strangers without expectation of personalgain. Voluntary organisations organise relief camps and provide medical facilities. Floods bring out the best in men to the surface. People throughout the world make collections and airlift relief materials to the victims. The increasing incidence of floods can be reduced by contruction of damsand catchment areas. These activites can't be carried out by a single man, but can be achived only by thr Government as these require colossal resources, organisation and manpower. Every single man can contrinute to pevent foold by planting trees and preventing denudation of vegetable plots. Forestation is one of the best alternatives to alternatives to arrest floods.
