IV. Read the passage.
A rocket uses fuel to make power for the engine. The fuel is set on fire inside the rocket. As the fuel burns, it creates gases that have great pressure. These gases are blasted out of the rocket engines.
These gases all go out the bottom of the rocket engine where it is open. They come out so fast and with so much power that the rocket is pushed up. It is pushed up so hard that the rocket overcomes the force of gravity, which tries to keep everything on the ground. The force that pushes up against the front of the rocket is called thrust.
Unlike an airplane, a rocket does not use wings to help it fly. It just uses the power and force created by the burning fuel to make enough thrust.
Decide whether the statements are True (T) or False (F).
1. A rocket uses the energy from wind to make power for the engine. .............
2. When the fuel burns, it creates gases that have great pressure. .............
3. These gases come so fast but they have little power. .............
4. The rocket is pushed up because it overcomes the force of gravity. .............
5. The rocket has two wings which help it fly. .............
V. Read the passage and answer the questions given.
It takes you about 16 hours to travel from New York to Beijing. Beside, 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 will take at least 20 hours. But in the future, this trip might only take 2 hours.
Nowadays, a private company is developing something called ET3 which stands for “evacuated tube transport technology”. Here is how it works. A tube goes all way from New York to Beijing. The tube is only a few meters wide. Capsules use move through the tube. Six people can sit in one capsule. The capsules use electricity instead of gasoline. The capsules can travel 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.
It is exciting to think of how ET3 will change in the future. Maybe someday, you will be able to have lunch in New York and dinner in Beijing.
Answer the questions:
1. How long will it take to travel from New York to Beijing if you travel by ET3?
.................................................................................................
2. What does ET3 stand for?
.................................................................................................
3. What does ET3 use to make engine?
.................................................................................................
4. How far does the most modern airplane usually fly in one hour?
.................................................................................................
5. Why does ET3 can travel that fast?
.................................................................................................
