[填空题]The Magic of Sound
Music is one of the most beautiful forms of artistic expressions ever invented. In movies and plays, music has an added function: it not only moves people but also can shock people. Is it true that an ordinary musical instrument can be so powerful
Our eardrums can withstand sound within 20 to 80 decibels. Once sound exceeds this limit, even beautiful music will become ear-splitting noise and harm health. A strong blast of high sound can twist and break a solid iron sheet. (46)
The noise from a plane’s engine is over 140 decibels. However, the sound of a flute is at most a few decibels. (47) It has been proven that people who have worked in an environment with a high sound intensity for a long time suffer varying degrees of heart disease or altered brain waves.
In movies, sometimes the hero can produce a sound that ordinary people can’t hear and only those who have the same ability can feel. In nature, there is ac

Music is one of the most beautiful forms of artistic expressions ever invented. In movies and plays, music has an added function: it not only moves people but also can shock people.
Our eardrums can withstand sound within 20 to 80 decibels(分贝). Once sound exceeds this limit, even beautiful music will become ear-splitting noise and harm health.A strong blast(响声) of high sound can twist and break a solid iron sheet. High sound of 150 decibels can kill a healthy rat.
In movies, sometimes the hero can produce a sound that ordinary people can’t hear and only those who have the same ability can feel.In nature, there is actually sound that is beyond our hearing. In physics, the sound that exceeds 20000Hz is called ultrasonic(超音波的). Dolphins, whales and bats can make such high-frequency sound. It does no harm to health.
Sound less than 20Hz is called infrasonic(次声)waves. When we move, the air will vibrate. The vibration o

[简答题]The Magic of Music
Music is one of the most common forms of entertainment. I can hardly think of anyone who doesn’t like music. It appears that wherever you go, music is playing or someone is listening to his or her MP3 or CD player. From middle school students to business executives, almost everyone seems to be a keen music lover. Why do people enjoy music so much I believe music works like magic: it pleases our senses, lightens our moods, and helps to develop friendship.
To begin with, music appeals to us greatly because heating is one of our most receptive and pleasure-feeling senses. Our ears are capable of heating and interpreting an extremely broad range of pitch and tones. Yet, other than music, the day-to-day sounds we usually hear are a scattered and unrelated series of overlapping middle tones, for example, voices and construction noise. The lack of harmony and variation in these sound waves can cause a headache. Conversely, music is the only kind of sound that is compr
[单项选择]Most people think of lions as strictly African beasts, but only because they’s been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe. Now lions hold a small fraction of their former habitat, and Asiatic lions, a subspecies that spit from African lions perhaps 100,000 years ago, hang on to an almost impossibly small slice of their former territory.
India is the proud steward of these 300 or so lions, which live primarily in a 560-square-mile sanctuary (保护区). It took me a year and a half to get a permit to explore the entire Gir Forest-and no time at all to see why these lions became symbols of royalty and gieatness. A tiger will hide in the forest unseen, but a lion stands its ground, curious and unafraid—lionhearted. Though they told me in subtle ways when I got too close, Gir’s lions allowed me unique glimpses into their lives during my three months in the forest. It’s odd to think that they are threatened by extinction; Git has a
A. have killed off other lions
B. have descended from African lions
C. used to span vast sections of the globe
D. have lost their habitat

Passage One
One of the most interesting experiments in electronic communication I’ve ever seen is coming from Wave. It’s real-time e-mail. What that means is that as you’re typing a message in Wave, either a new message or a reply, the person you’re writing to can see what you’re typing as you type it. Sounds awful, right
You don’t have to use Wave in this real-time way. It also works as a standard e-mail. What’s really different about Wave is that if you’re replying to a message and the person you’re replying to happen to be online, they can jump into the conversation at that point, and change what is an e-mail conversation into an instant message conversation or a chat.
Wave right now is still closed to most users. And Wave isn’t yet connected to other communication systems, like regular e-mail, which means that the only people we can Wave with are other people on Wave as well. So we don’t yet know what using Wave will be like
A. It makes people see each other online.
B. It enables people to send real-time e-mails.
C. It allows you to send more e-mails at the same time.
D. It can be easily connected to other communication systems.
