How Long Can People Live?
She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121 st birthday.
When it comes to long life, Jeanne Calment is the world’s record holder. She lived to the ripe old age of 122. So is 122 the upper limit to the human life span（寿命）? If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond?
Researchers don’t entirely agree on the answers. “Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,” says Jerry Shay at the University of Texas.
Steve Austad at the University of Texas agrees. “People can live much longer than we think,” he says. “Experts used to say that humans couldn’t live past 110. When Calment blew past that age, they raised the number to 120. So why can’t we go higher?”
The trouble with guessing how old people can live to be is that it’s all just guessing. “Anyone can make up a number,” says Rich Miller at the University of Michigan. “Usually the scientist who picks the highest number gets his name in Time magazine.”
Won’t new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the life span of mice by 50 percent at most. So, if the average human life span is about 80 years, says Miller, “adding another 50 percent would get you to 120.”
So what can we conclude from this little disagreement among the researchers? That life span is flexible（有弹性的）, but there is a limit, says George Martin of the University of Washington. “We can get flies to live 50 percent longer,” he says. “But a fly’s never going to live 150 years.” Of course, if you became a new species （物种）, one that ages at a slower speed, that would be a different story, he adds.
Does Martin really believe that humans could evolve （进化）their way to longer life? “It’s pretty cool to think about,” he says with a smile.

Now some women are spending a weekend at Mother’s Camp（营地）. There, husbands and children are not allowed. Why would a woman want to take a vacation without her family? Some women say they need time to be alone.
At Mother’s Camp a woman has room to herself. She can sleep, read or watch TV, and no one will bother her. No children will ask, “Mom, what’s for dinner?” No husband will say, “Oh, dear, I can’t find any clean socks.” In fact almost 50% of women in the United States work outside the home. Many of them work full-time and then come home to a second job----taking care of their homes and families. These working women say one of their biggest problems is housework.
In the United States, working wives do about 75% of the housework. Many of their husbands say they want to help. But then they burn the rice or they can’t find the pans. They ask so many questions that their wives decide it is easier to do the job themselves.

All around the world, people drink tea. But tea does not mean the same thing to everyone. In different countries people have very different ideas about drinking tea.
In China, for example, tea is always served when people get together. The Chinese drink it at any time of the day at homes or in teahouses. They prefer their tea plain with nothing else in it. Tea is also important in Japan. The Japanese have a special way of serving tea called a tea ceremony. It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in Japanese homes.
Another tea drinking country is England. In England, the late afternoon is “teatime”. Almost everyone has a cup of tea then. The English usually make tea in teapot and drink it with cream and sugar. They also eat cakes, cookies and little sandwiches at teatime.
In the United States people drink tea mostly for breakfast or after meals. Americans usually use tea bags to make their tea. Tea bags are faster and easier than making tea in teapots.

About ten years ago, a young and very successful businessman named Josh was traveling down a Chicago neighborhood street. He was going a bit too fast in his shiny, black, 12 cylinder Jaguar XKE, which was only two months old.
He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something. As his car passed, no child came out, but a brick sailed out and—WHUMP! —it hit the Jag’s shiny black side door! Immediately Josh stopped the car, jumped out, seized the kid and pushed him up against a parked car. He shouted at the kid, “What was that all about and who are you? That’s my new Jag, that brick you threw is gonna cost you a lot of money. Why did you throw it? ”
“Please, mister, please. . . I’m sorry! I didn’t know what else to do! ” begged the youngster. “I threw the brick because no one else would stop! ” Tears were streaming down the boy’s face as he pointed around the parked car. “It’s my brother, mister” he said. “He rolled off the curb (路沿) and fell out of his wheelchair and I can’t lift him up. ”Sobbing, the boy asked the businessman, “ Would you please help me get him back into his wheelchair? He’s hurt and he’s too heavy for me. ”
Moved beyond words, the young businessman tried hard to swallow the rapidly swelling lump in his throat. Straining, he lifted the young man back into the wheelchair and took out his handkerchief and wiped the scrapers and cuts, checking to see that everything was going to be OK. He then watched the younger brother push him down the sidewalk toward their home.
It was a long walk back to the black, shining 12 cylinder Jaguar XKE—a long and slow walk. Josh never did fix the side door of his Jaguar.

The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance (香气). From air fresheners to scented (有香味的) candles, we live in a world of scent.
Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (过敏), headaches and asthma (哮喘) .
One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (湿疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.
“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”
People with pre-existing eczema are particularly vulnerable (易受影响). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.
And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.
“Fragrance suggest cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”What is the text mainly about?
| A．The world trend of using fragrance. |
| B．The benefits of using non-fragranced products. |
| C．The health problems caused by fragrance |
| D．The ways of removing allergy. |
According to Dr. Baron, .
| A．our bodies have an immediate reaction to fragrance. |
| B．seven in ten have suffered fragrance allergy. |
| C．fragrance can affect people who don’t have allergy |
| D．people can avoid contacting with fragrance easily |
Which of the following questions does the text NOT answer?
| A．Which products contain fragrance? |
| B．What’s the influence of fragrance in the air? |
| C．What are the air fresheners made up of? |
| D．How are headaches caused by fragrance? |
The following paragraph might discuss.
