1.Sources of energy
Solar power harvests the energy of the sun through using collector panels to create conditions that can then be turned into a kind of power. Large solar panel fields are often used in desert to gather enough power to charge small substations, and many homes use solar systems to provide for hot water, cooling and supplement their electricity. The issue with solar is that while there is plentiful amounts of sun available, only certain geographical ranges of the world get enough of the direct power of the sun for long enough to generate usable power from this source.

Why we shouldn’t get too excited over the shale boom
Why resource depletion is a greater threat than climate change
Why Fukushima should not be seen as a reason to abandon nuclear
Why the Keystone XL pipeline may do little to help US energy security
Why renewables have difficulty mitigating a liquid fuels shortage
Why we shouldn’t rely on science to solve our energy problems
Forget fusion and thorium breeders – artificial photosynthesis would be a bigger game changer

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.

- Topic 4: Souces of energy.
1. What are renewabe/ non-renewable sources of energy?
==>-Renewable energy sources include: hydro, solar, biomass, heat, biology, tides, wind.
-Renewable energy sources are fossils (petroleum, coal, rock), nuclear (uranium).
2. What are advantages of solarpower/ wind power?
Benefits of solar energy:
- convenient facilities - where there is sunlight with electricity. Our father has a wonderful saying: "run from the sun", very true, almost anywhere on earth are sunny in the day
. Endless energy. According to scientists, the existence of the sun is still several billion years, so you can rest assured that the use is not afraid of it!
- The cleanest and safest source of energy. Sunlight brings life to the earth so it is the safest course.
Free energy source. No one can control, charge for this form of energy. It gives all the creatures on earth, less space depending on geographic location.
Easy to use energy source. You are using it daily, in different ways like sun drying, sun drying, tree planting, light you see everything ...
Benefits of wind energy:
- Save on fuel, second is the ability to replace fast. Third reduce the toxic waste from the energy works into the surrounding environment.
What are disadvantages of fossil fuels?
==> The downside is that fossil fuels are a non-renewable resource because the Earth took millions of years to produce them, and the consumption is taking place faster than the speed of creation that results in exhausted fossil fuels.
3. Do you think people will use solar energy widelyin the future? Why?
==> I think people will use solar energy extensively in the future because solar energy is very useful and an endless source of energy.
