Traveling in the Future
These days, if you want to travel from New York to Beijing, the flight takes about 16 hours. You also have to wait at the airport, and sometimes you have to transfer onto a different airplane. If you add all of that extra time, the trip takes at least 20 hours. But in the future, the trip from New York to Beijing might only take two hours.
Right now, a private company is developing something called ET3. ET3 stands for “evacuated tube transport technology”. Here is how it works. A tube goes all the way from New York to Beijing. The tube is only a few meters wide. Capsules move through the tube. Six people can sit in one capsule. The capsules use electricity instead of gasoline. For international travel, the capsules can travel at about 6,500 kilometers per hour. That is much faster than airplane - most modern airplanes usually only fly at about 800 kilometers per hour.
So how is this possible? How can these capsules travel so fast? The answer is that there is no air inside the tube. When airplanes fly, they have to move through the air. The air slows the airplanes down. Because there is no air in the ET3 tubes, the capsules are able to move at a very high speed. Besides, the capsules are quite light. They only weigh 183 kilograms.
There are other advantages to ET3. Because it uses electricity, it is quite clean. In addition, it is much quieter than airplanes and cars. Finally, ET3 tubes and capsules don’t require very much building material.
Of course, ET3 doesn’t exist yet. The technology is still being developed. Developers still have to solve a lot of problems. The biggest problem is that right now, ET3 would be far too expensive. In order to make ET3 cheaper, we will need much better technology.
It is exciting to think of how ET3 will change travel in the future. Maybe someday, you will be able to have lunch in New York and dinner in Beijing.

Vietnamese often don’t obey the traffic lights or signs. Children are taught about traffic laws while adults are breaking it.

Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.
VI. Read the text then answer true or false
People use many sources of energy. Ancient people used only their arms, hands, and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the eighteenth and nineteenth centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy. Energy is one of the basic concepts, or ideas, of physics. It is the ability to do work. Without energy we could live. We need energy to work, and scientists are always looking for new sources of energy.
1. None of the world’s energy comes from the sun. F
2. Wind, steam, and gasoline are sources of energy. T
3. People have never used nuclear energy. F
4. Energy is the ability to do work. T
5. We need new sources of energy. T
