Music forms an important part of many cultural and social activities. People use music to feeling and ideas. Music also serves to entertain(娱乐) and relax.
Music is a performing art. It differs from such art as painting and poetry, in which artists create works and then display or publish them. Music composers(作曲家) need musicians to explain the meaning of their works --- perform them. Thus, musical performances are partnership between composers and performers.
Music is one of the arts. Hunting tools struck together may have been the first musical instruments. Many ancient people, including the Egyptians, Chinese and Babylonians, and the people of India, used music in court and religious ceremonies(宗教仪式). The first written music dates from about 2500 B.C.
Classical music, also art music, is composed according to certain rules and performed by musicians from written music. Classical composers have written different styles of music during different periods of .
Popular music includes many kinds of music, country music, jazz, rock music and music from films. Popular music is generally much simpler than classical music.
Folk music is made up of the old songs. Most folk songs began in distant areas. One person makes up a song and other people it and learn to sing it. Some folk songs have been passed on in this way for thousands of years. Many composers of classical music have used folk music in their works.

Do you to write with your left hand? If you do, you are one of the millions of “lefties” in the world. Why do some people use left hand more often than others? To understand left-handedness, it is necessary to look at the . The brain is divided into two hemispheres（半球）. The left hemisphere is the center of language and logical thinking. This is where they do their math problems and memorize words. However, the hemisphere controls how they understand ideas and they respond（作出反应） to the five senses—sight, hearing, , taste, and touch. The left hemisphere controls the right side of the body, the right hemisphere controls the left side. Both sides of the body receive the information from the brain because they are connected(联系). In right-handed people, the left hemisphere is stronger. In left-handed people, the right hemisphere is .
Lefties prefer not only the left hand but also the left . They would rather use the left foot to kick a ball because their whole body is “left-handed”.

How many things can you see in the night sky? A lot! a clear evening you might see the Moon and some planets. And thousands of sparkling stars , too.
You can see even with a telescope. You might see stars where you only saw dark space before. You might see that many stars look larger than others. You might see that some stars look white are really red or blue.
But scientists believe there are some things in the sky that we . We can’t see them with the biggest telescope in the world, even when it is the clearest night of the year. That’s they’re invisible. They’re the mysterious dead stars called black holes. You might find hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn’t seem getting old or weak. But stars do burn out and die after billions of years. As a star’s gases burn, they give off light and heat. But when the gas runs , the star stops burning and begins to die.
So the next time you stare up at the night sky, remember: there’s more in the sky than that meets the eye. amazing space it is!

A new study finds that plants communicate with one another to warn of danger.
We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds, they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is chemical.
Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighboring plants. These chemical warnings can spread information about one plant’s disease or infestation(虫害), so other plants can protect themselves. But how plants receive and act on many of the information exactly is still mysterious.
In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.
The scientists looked at tomato plants infested by a common pest(害虫). To start out, they grew plants in two separate plastic spaces connected by a tube(管子). One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed(暴露) to the pest. The results showed that plants near sick neighbors before were able to protect themselves better against the pest.
They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic come from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbors.
It is not a simple story, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
The underlined “traced” in the fourth paragraph probably means _________ here.
| A．reported | B．followed |
| C．doubted | D．developed |
For scientists, which are the right steps to watch tomato plants infested by a pest?
① Place the infested plant upwind.
② Place the uninfested plant downwind.
③ Expose the downwind plants to the pest.
④ Grow plants in two separate plastic spaces connected by a tube.
| A．③①②④ | B．①④③② |

| A．Paragraph 3 | B．Paragraph 4 |
| C．Paragraph 5 | D．Paragraph 6 |
Which of the following can be the best title of this passage?
