Do you know that men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
　　The largest study of the effects of ageing(变老) on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
　　“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
　　“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”
　　What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
　　“This gender difference might just explain why women live longer than men,” said Goldspink. They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease. “The team has yet to find why ageing takes a greater loss on the male heart,” said Goldspink.
　　The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
【小题1】 The underlined word “longevity” in the second paragraph probably refers to “________”.

【小题2】 The text mainly talks about ________.

A．men’s heart cells	B．women’s ageing process、
C．the gender difference	D．hearts and long life

【小题3】According to the text, the UK scientists have known that ________.

A．women have more cells than men when they are born

B．women can replace the cells that enable the heart to beat

C．the female heart loses few of the cells with age

D．women never lose their pumping power with age

【小题4】If you want to live longer, you should ________.

A．enable your heart to beat much faster

B．find out the reason for ageing

C．exercise regularly to keep your heart healthy

D．prevent your cells from being lost

【小题5】We can know from the passage that ________.

A．the reason why ageing takes a greater loss on the male heart has been found out

B．scientists are on the way to finding out why the male heart loses more of the cells

C．the team has done something to prevent the male from suffering the greater loss

D．women over 70 could lose more heart cells than those at the age of 20

Babies are born yogis. Once we were all able to pull our toes up by our ears and laugh about it. Then we aged, got injured, and began carrying stress in our shoulders and back. In short, we lost our balance.
Yoga（瑜伽） is an ancient practice that helps create a sense of union in body, mind, and spirit. It brings us balance. I was seriously out of balance when I started practicing yoga in 1999. I had plantar facilities in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis. I was desperate for exercise. Yoga became my salvation and even enhanced my other fitness activities. I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it.
Yoga becomes part of your physical life. Your body grows stronger, more toned, and more flexible as you move from one pose to the other. I spent a week in Mexico at a yoga retreat, and it was the first vacation on which I lost weight. “Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K.I.S.S. Guide to Yoga. “Because yoga helps maintain a balanced metabolism (新陈代谢), it also helps to regulate weight. Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells.” I do yoga poses throughout the day. After hours at my computer, I stretch my stiff shoulders and arms. When I need a boost of energy, I do energizing poses. When I am feeling exhausted at the end of the day, I do restorative poses.
Yoga becomes part of your mental life. Yoga teaches you to focus on breathing while you hold the poses. This attention to breath is calming; it dissolves stress and anxiety. I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams. You should always leave a yoga practice feeling energized, not tired. If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses. In yoga, you “surrender” to the pose by letting go of the tension.
Yoga becomes part of your spiritual life. Yoga is practiced by people from all religions; it is not restricted to any religious group. Yoga teaches “right” living in how we deal with ourselves and others. As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness. Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga.
【小题1】What would be the best title for this passage?

A．What’s Yoga?	B．How I Do Yoga Poses
C．The Benefits of Yoga	D．The Varieties of Yoga

【小题2】According to the third paragraph, yoga can help people __________.

A．grow taller	B．lose weight
C．become flexible in thinking	D．make more friends

【小题3】People feel tired after yoga because __________.

A．they consume energy in practicing yoga

B．they respond well to yoga poses

C．they spend too much time on yoga

D．they force themselves into yoga poses

【小题4】If this passage continues, what will the writer most probably write about in the next paragraph?

A．Yoga as a means to keep fit.	B．Who may like yoga
C．Popularity of yoga all over the world.	D．Encouraging people to do yoga.

Welcome to your future life!

You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people at your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!www.zxxk.com

You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles (粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes’ color or pattern.

You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.

It’s time to go to work. In 2025, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.

So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?

As you dash outdoors in the middle of winter, you might make it halfway down the block before realizing that your ears are freezing because you forgot your hat.

Now, scientists have shown that even though you’ve had an apparent memory lapse（丧失）, your brain never forgot what you should have done.

Memory works mainly by association. For example, as you try to remember where you left your keys, you might recall you last had them in the living room, which reminds you that there was an ad for soap on television, which reminds you that you need soap, and so on. And then, as you’re heading out of the door to buy soap, you remember that your keys are on the kitchen counter. Your brain knew where the keys were all along. It just took a round-about way to get there.

Now, scientists at the Salk Institute for Biological Studies are studying associative memory in monkeys to figure out just how this complicated process works.

First, the researchers trained a group of monkeys to remember arbitrary（任意的） pairs of symbols. The researchers showed the monkeys one symbol（cold weather） and then gave them the choice of two other symbols, one of which （a hat） would be associated with the first. A correct choice would earn them a sip of their favorite juice.

Most of the monkeys performed the test perfectly, but one kept making mistakes.

“We wondered what happened in the brain when the monkey made the wrong choice, although it apparently learned the right pairing of symbols,” said study leader Thomas Albright.

Albright and his team observed signals from the nerve cells in the monkey’s inferior temporal cortex （ITC）, an area of its brain used for visual pattern recognition and for storing this type of memory.

As the monkey was deciding which symbol to choose, about a quarter of the activity in the ITC was due to the choice behavior.

Meanwhile, more than half the activity was in a different group of nerve cells, which scientists believe represent the monkey’s memory of the correct symbol pairing, and surprisingly, these cells continued to work well even when the monkey chose the wrong symbol.

“In this sense, the cells ‘knew’ more than the monkeys let on in their behavior,” Albright said. “Thus, behavior may vary, but knowledge endures.”

C. Monkeys have better memory than us.

D. Your brain may forget something, but not always.

2. The example of the keys and soap is given to explain the relationship between _______.
