Flying the Hypert Skies
A little airplane has given new meaning to the term "going hyper."
The Hyper-X recently broke the record for air-breathing jet planes when it traveled at a hypersonic speed of seven times the speed of sound. That’s about 5,000 miles per hour. At this speed, you’d get around the world -- flying along the equator -- in less than 5 hours.
The Hyper-X is an unmanned, experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine known as a scramjet. It may sound like something from a comic book, but engineers have been experimenting with scramjets since the 1960s.
For an engine to burn fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. A scramjet engine goes as fast as a rocket, but it doesn’t have to carry its own oxygen
A. It goes slower than a rocket.
B. It extracts oxygen from the air that flows through the engine.
C. It works only at speeds greater than five times the speed of sound.
D. It doesn’t carry its own oxygen supply.

[单项选择]Communication is the sending of information or news from one person to another. If human beings could not communicate with one another, each person would have to learn everything for himself. Although animals as well as men can communicate, so far as we know, they can express only the simple emotions like pain, joy, fear, hunger, anger and love. Some animals have a more advanced form of language using sounds, and others use a wide range of sounds and face movements, but we still have much to learn about these animal languages.
Speech is the most important means of communication between people. But it is not the only one. Nor is it the oldest. We use facial expressions, gestures and hand movements to express our feelings and to send signals to other people. Animals use this "body language" a great deal. The sign language used by deaf people is an example of communication without speech,while blind people communicate largely through touch and hearing.
Which of the following state
A. Humans do not have adequate knowledge about animal languages.
B. We are now very much aware of animal languages.
C. Most of animals use their facial expressions.
D. All animals make sounds to communicate with each other.
