Today, there are many hot issues that are being paid great attention by the whole society such as education, food safety and hygiene, continuous evils and especially traffic safety issues. Today's presentation will give you an understanding of this field. Traffic is the movement between vehicles such as motorcycles, cars, ships, planes ... on different distances, types of roads such as roads, railways, airways ... Participation and regulation of traffic Information is not easy because the amount of traffic is increasing, especially roads. The current traffic situation is ringing an urgent bell about human consciousness. One day, in Vietnam, there are dozens of accidents, even very serious accidents, especially on peak occasions such as festivals or Lunar New Year. Recently, public opinion is very pity for the strawberry caravan incident with eleven people killed. The joy of the whole family line suddenly turned into pain, the disaster struck everyone. One thing that is making us very indignant is the container incident that caused the catastrophic accident for people who stopped red lights. It is special that the driver has been confirmed to be positive for drugs. All someone's passing away from a traffic accident ultimately comes from the irresponsibility, indifference, and disregard for the lives of such people. Traffic accident not only kills a human's life, the biggest loss, but also causes great damage to material possessions. This is damaging to the economy, social disorder, making people worried and insecure and inhibiting the development of our country. Above all, the relatives of the ill-fated victims will suffer lasting damage, forever the scar that will never disappear. Therefore, ensuring traffic safety is very important and urgent. Everything works only when it comes from one's own consciousness. Let's obey the law when entering traffic from the smallest actions such as wearing a helmet, stopping the red light, not exceeding speed ... This will help you largely avoid the risk of having an unfortunate incident. However, you should also remember that helmets must be quality helmets, must be fitted with straps to take advantage of its effect. If you stop the red light, you must wait for the green light to go, not "one second fast, a lifetime slow" ... Besides, we also need to regularly organize propaganda activities to guide people to participate in communication. information properly, especially with the student's age. The concerned authorities, especially the traffic police forces, have to constantly patrol, control and frankly handle violation situations to set an example. Traffic safety is your way to contribute to society. It is not always economic support or charitable donations that help the country develop. First of all, you should be consciously protecting your life when in traffic. It's how you love yourself and keep others from worrying about you. And people have everything. Your body is cold, healthy is still abundant, you can work, make a lot of money and fulfill your dreams.

In the future, I think people won't be worried about travelling because of teleporters.It will look a big magic box or maybe it will be designed as a magic lift.In my opinion, it will be powered by solar energy and it will combine the function of a 3D map. Just think about going into a teleporter in France and choosing Vietnam as the destination. Then, 3 minutes later, you will be in Hanoi - Vietnam. That will be great.People can use it anytime and anywhere. It won't take a lot of space.I think it will replace all other vehicles and it will make people around the world closer.
I think in the future, most people will travel by flying cars.I think that it will have 2 wings so that it can fly as a plane. It will not be as big as the plane, but its speed will be higher than any other vehicles now.I think flying cars will use solar power with super thin batteries and they will use the technology called Vehicle-to-Vehicle communication, or V2V, which means cars will communicate with each other to avoid crashing. A flying car will be used for air transport, but it can also be used on the road. People can control it by touching on the control panel or they can set it in the automated control system. It can be used both in the city and in the countryside.I think flying cars will be one of the most popular means of transport in the future because they are environmentally friendly and we can avoid traffic jams by using them. However, I think we may need a sky safety system to avoid crashing.I think flying cars will be one of the most popular means of transport in the future because they are environmentally friendly and we can avoid traffic jams by using them.

Harry Potter is one of my favourite movies. I have loved it since it was held in the theatre years ago. Based on the best seller fiction written by JK.Rowling, the movie makes it real. This movie was about Harry Potter, he is a wizard born in the dark days of the wizardry world. His parents died in the hand of Voldemort, the dark lord. During his journey, he experienced a lot: happiness, sadness, live and death moments, etc. At last, he finally beat Voldermort and became a great auror like his parents. This movie taught me many things. The most important thing for me is that love and friendship will always be there for those who deserve it and fight for it. I’d recommend this movie for everyone.

Trong thế giới cơ khí hàng hải, supercavitation là phương pháp tăng tốc bá đạo nhất. Supercavitation là một hiệu ứng được tạo ra khi một lớp bóng khí hình thành xung quanh một đối tượng bên trong một chất lỏng (thử tưởng tượng phần ngập nước của tàu được bong bóng bao quanh). Lớp khí làm giảm ma sát 900 lần so với bình thường, giúp phương tiện di chuyển nhanh hơn nhiều so với việc di chuyển trong mặt nước.
Do đó bất cứ chiếc tàu nào trang bị công nghệ này đều là tài sản to lớn cho mọi đội hải quân. Ngoài việc nhanh và ít tốn nhiên liệu, tốc độ và hình dáng của nó khiến nó dễ dàng qua được sóng âm định vị. Thậm chí nó còn cho ngư lôi ngửi khói trong cuộc đua. Juliet Marine Systems, một công tư nhân tại Portsmouth, New Hampshire, đang cố gắng làm ra một chiếc như vậy. Nó được gọi là BÓNG MA, được tạo ra với mục đích phòng thủ - bảo vệ cho các tàu hải quân, và đánh đuổi lũ cướp biển lăm le dòm ngó các tàu thương mại. Nó cũng có thể là một chiếc phà đầy hiệu quả trong việc đổ bộ bờ biển của quân địch.

Do you believe that flying cars have appeared 70 years ago? Since writer Jules Verne introduced the idea of flying cars in the novel Master of the World, published in 1904, generations of engineers have been trying to make flying cars. In 1940, Henry Ford (founder of Ford Motor Company) predicted that the combination of aircraft and cars would occur at a time when both low cost and cheaper aircraft and cars were mass use. The combination of these two vehicles is inevitable. Ford's prediction proved to be true. Only a few years later, an aeronautical engineer named Ted Hall launched the first fully functional flying car.
