  GOOGLE (www. google. torn) is a daily miracle to millions of people. If the Internet had only this very fast search engine, it would have justified its existence many times over. It is the most popular search engine on the web with a 54% market share, ahead of Ya-hoo! You type almost anything, however un-clear, into the space provided and in a second it has come up with hundreds of references. If knowledge is power, then Google commands the gateway.

Yahoo Becomes Giant

  YAHOO (www. yahoo, com) was the first wonder of the web, and in many re-spects, it still is. It started in January 1994 when two California graduate students, Jerry Yang and David Filo, started compiling (編 譯) a database of links, mainly for their per-sonal use. But well before the end of the year, it had become recognizable as Yahoo we know today. In the past seven years, Yahoo had grown rapidly, partly through a long string of buy. Yahoo now offers almost eve-rything you could want: e-mails, instant mes-sages, chats, clubs, photo albums and a lot more.

  eBAY (www. ebay. com), which deals with online trading and shopping services, is the most impressive large Internet company where people buy and sell goods and services worldwide. It has, for instance, opened up a global marketplace in which people from Bei-jing, San Francisco, or Moscow can bid (投 標) against each other for products put up for sale by someone in London. The company's online service permits sellers to list items for sale, buyers to bid on items of interest, and eBay users to browse (瀏覽) through listed items that is available online seven days a week.

Amazon Makes Buying a New Experience

  Amazon (www. amazon. com) started out as an online bookstore, constantly putting up new book . titles it offered for sale. In the late 1990s, Amazon had more than four mil-lion titles after adding CDs, videos, DVDs and games. It continued to add new lines of busi-ness including toys, computer software, elec-tronics, like MP3 players, power tools, home improvement products and online sales. For regular users, Amazon has made itself the shortest possible path between wanting and buying.

If you want to keep fit, please refer to the following:

   Move More

   Make it a daily to find ways to move your body.     Climb stairs instead of taking the elevator. Walk your dog; play with your kids. It doesn’t have to be an hour in the gym or a 45-minute dance class. But that’s great when you’re up to it. At the same time, move more.

   Quit Smoking

   Ever since 1960 when it was announced that smoking was harmful to health, Americans have been reducing their use of tobacco products. Just recently, we’ve seen more and more teens smoking. Could it be the Hollywood influence?    Take care! Warn your children against smoking.

   

While recent studies show a glass of wine or one drink a day can help protect against heart disease, more than that can cause other health problems such as liver and kidney(肝腎) disease and cancer.

Reduce Stress

Easier said than done, stress comes in many ways.     Spend 30 minutes a day doing something you like such as walk on the beach or in a park, read a good book, visit a friend, listen to relaxing music, and watch a funny movie.

Protect Yourself from Pollution

If you can’t live in a smog-free environment, at least avoid smoke-filled rooms.     Exercise indoors in air conditioning when air quality is good.

A. Avoid Excessive Drinking

Think of some of your favorite singers. When you listen, they can make you happy or sad, peaceful or angry. They can make you relax or want to get up and dance. Gifted singers have the power to affect us in many ways—emotionally, physically and mentally.
But becoming a great singer isn’t as easy as listening to one. It takes practice, devotion and strong lungs! Just ask the well-known American opera(歌劇)star Carol Vaness.
At the Metropolitan Opera in New York City where she often sings, Carol’s voice must be loud enough to be heard by four thousand people. It must reach every person in the theater, without a microphone, even when she’s singing softly. The reason Carol can project her voice that far is the way she breathes.
“When you breathe, it’s like a swimmer taking a deep breath before going underwater,” Carol explains. “You have to take a lot of air into your lungs.”
According to Carol, the main difference between pop singing and opera is “how you breathe, how much air you take in, and how you control it coming out. Regular singing is more like speaking, and it’s lot softer. When I sing for children, they’re often surprised by how the vibrations strike their ears—like waves on a beach, ”Carol says. “In opera, the air doesn’t just go out of your mouth—it vibrates in your chest,the way a guitar vibrates when it’s played.”
Ever since she started piano lessons at the age of ten, Carol has loved music. As she got older, she decided to become a music teacher. When she went to college, she took singing lessons as part of her studies. Her voice teacher discovered that nineteen-year-old Carol had an exceptionally beautiful soprano voice-the highest singing voice for women.
Carol decided to make opera her goal, not only because she loved to sing but also because she loved the drama. Opera is a play in which the characters sing the words instead of speaking them. The stories of opera can be tragic or comical. They can be personal stories about two people falling in love or grand stories about kings and queens who lived long ago. As the characters in an opera sing, the emotions(情感)expressed by words and music come to life.
Today, Carol performs throughout the United States and Europe and she has song for almost twenty years. But she has never forgotten where she started singing in the first palace.
“Put your heart into your singing and enjoy it,” says Carol, “because singing is a great joy. That’s why I sing. In fact, that’s why everybody sings.”
【小題1】According to the passage,  the Metropolitan Opera in New York City     .

A.is a five-story buildingB.can seat 4,000 people
C.has no microphone in itD.can project the singer’s voice
【小題2】What is the best title for this passage?
A.Opera Singing and Pop SingingB.The Way an Opera Star Sings
C.An Opera StarD.Singing without a Microphone
【小題3】Which statement is true?
A.A pop singer’s lungs are usually stronger than those of an opera singer’s
B.Opera singing is more like speaking.
C.A pop singer takes in much more air than an opera singer when singing.
D.An opera singer breathes differently from a pop singer when singing.
【小題4】From the passage you can conclude all the following EXCEPT that     .
A.Carol once learned to play the piano
B.Carol worked as a music teacher
C.Carol has been singing opera for 20 years or so
D.Carol is popular with Americans and Europeans

Empathy
Last year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students had dropped sharply over the past 10 years. __71__ Today, people spend more time alone and are less likely to join groups and clubs.
Jennifer Freed, a co-director of a teen program, has another explanation. Turn on the TV, and you’re showered with news and reality shows full of people fighting, competing, and generally treating one another with no respect. __72__
There are good reasons not to follow those bad examples. Humans are socially related by nature. __73__ Researchers have also found that empathetic teenagers are more likely to have high self-respect. Besides, empathy can be a cure for loneliness, sadness, anxiety, and fear.
Empathy is also an indication of a good leader. In fact, Freed says, many top companies report that empathy is one of the most important things they look for in new managers. __74__ “Academics are important. But if you don’t have emotional intelligence, you won’t be as successful in work or in your love life,” she says.
What’s the best way to up your EQ (情商)? For starters, let down your guard and really listen to others. __75__
To really develop empathy, you’d better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a “sharing circle” with your family, or spend time caring for pets at an animal shelter.

A.Everyone is different, and levels of empathy differ from person to person.
B.Having relationships with other people is an important part of being human—and having empathy is decisive to those relationships.
C.Humans learn by example—and most of the examples on it are anything but empathetic.
D.“One doesn’t develop empathy by having a lot of opinions and doing a lot of talking,” Freed says.
E. Empathy is a matter of learning how to understand someone else—both what they think and how they feel.
F. Good social skills—including empathy—are a kind of “emotional intelligence” that will help you succeed in many areas of life.
G. That could be because so many people have replaced face time with screen time, the researchers said.

Below is a selection from a popular science book.

If blood is red, why are veins (靜脈) blue?

Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in a vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.

Which works harder, your heart or your brain?

That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.

Why do teeth fall out, and why don’t they grow back in grown-ups?

Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall out when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.

Do old people shrink as they age?

Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They simply lose height as their spine (脊柱) becomes shorter and more curved due to disuse and the effect of gravity (重力). Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards—their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.

Why does spinning make you dizzy (眩暈的)?

Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’re moving while you’re not!

Where do feelings and emotions come from?

Mostly from an ancient part of the brain called the limbic system. All mammals (哺乳動物)have this brain area — from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on the planet.

If exercise wears you out, how can it be good for you?

Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy; it’s more that a lack of exercise leaves your body weak and easily affected by disease.

1.What is the color of blood in a vein near the surface of the skin?

A. Blue      B. Light yellow

C. Red        D. Dark reddish purple

2.Why do some old people look a little shrunken as they age?

A. Because their spine is in active use.

B. Because they are more easily affected by gravity.

C. Because they keep growing backwards.

D. Because their spine becomes more bent.

3.Which of the following statements about our brain is true?

A. In the long run, our brain probably works harder than our heart

B. When our brain senses the spinning, we will feel dizzy.

C. The brains of the other mammals are as complex as those of humans.

D. Our feelings and emotions come from the most developed area in our brain.
