Why do 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 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 ageing 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.
The underlined word “longevity” in the second paragraph probably refers to ________.

A.health B.long life C.ageing D.effect

The text mainly talks about ________.

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

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

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

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

Where Are We Going, Dad? has become one of China's most popular television shows, since its debut (首次登场) in October, averaging more than 600 million viewers each week. Sponsorship rights (冠名权) for the show's second season were sold for 312 million yuan (about $ 50 million), more than ten times higher than the rights to the first season.
What accounts for its popularity? The show features a new generation of Chinese fathers, who, as part of the country’s new middle class, have faced more problems with modern child-raising techniques such as taking an active role with their children.
Part of the appeal of the show is the chance to throw a glance at the lives of Chinese celebrities (名流) and their children. Audiences are interested in watching the failed attempts of celebrity dads making dinner, doing hair, and disciplining (管教) children -- tasks often left to mothers in a society still influenced by the saying that “men rule outside and women are inside.” “In traditional Chinese culture, fathers are strict and mothers are kind. But on the show, we see fathers who are much gentler on their kids and more involved in their upbringing, ” said Li Minyi, an associate professor. “This show raises an important question for modern Chinese society -- what is the role of fathers in today’s China?”
After each episode (集) goes to air, the Chinese internet explodes with comments on each celebrity's parenting style.
Actor Guo Tao tries to communicate with his son, Shitou, but is seen as a more traditional Chinese father, and has been criticized online for being too harsh. Zhang Liang. a supermodel, is an audience favorite for treating his son. Tiantian, more like a friend. The show’s most famous celebrity. Lin Zhiying, a film star, was originally praised as patient with his son Kimi. But as the season progresses, fans begin to criticize him for raising a spoiled, undisciplined boy. Director Wang Yuelun is at a complete loss when it comes to care of his daughter’s hair.

Would you like to be a king or queen? To have people waiting on you hand and foot? Many Americans experience this royal treatment every day. How? By being customers. The American idea of customer service is to make each customer the center of attention. Need proof? Just listen to the commercials. Most of them sound like the McDonald’s ad: “We do it all for you.” Actually, not all stores in America roll out the red carpet for their customers. But wherever you go, good customer service means making customers feel special.
People going shopping in America can expect to be treated with respect from the very beginning. Most places don’t have a “furniture street” or a “computer road” which allow you to compare prices easily. Instead, people often “let their fingers do the walking” through the store hot lines. From the first “hello”, customers receive a satisfying response to their questions. This initial contact can help them decide where to shop.
When customers get to the store, they are treated as honored guests. Customers don’t usually find store clerks sitting around watching TV or playing cards. Instead, the clerks greet them warmly and offer to help them find what they want. In most stores, the clear signs that label each department make shopping a breeze. Customers usually don’t have to ask how much items cost, since prices are clearly marked. And unless they’re at a flea market or a yard sale, they don’t bother trying to bargain.
When customers are ready to check out, they find the nearest and shortest checkout lane. But as Murphy’s Law would have it, whichever lane they get in, all the other lanes will move faster. Good stores open new checkout lanes when the lanes get too long. Some even offer express lanes for customers with 10 items or less. After they pay for their purchases, customers receive a smile and a warm “thank you” from the clerk. Many stores even allow customers to take their shopping carts out to the parking lot. That way, they don’t have to carry heavy bags out to the car.
By quoting (引用) the McDonald’s ad: “We do it all for you”, the author intends to_______.

A.suggest that customers believe what commercials say deeply
B.show readers the American idea on good customer service
C.express all the stores pay much attention to the customers
D.persuade readers to choose the stores with ads correctly

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries(食品杂货),saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity(人性)as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.
Why was the bike so important to the couple?

A.The man’s job was bike racing.
B.It was their only possession.
C.It was a nice Kona 18 speed.
D.They used it for work and daily life.

We can infer from the text that ____________.

A.the couple worked 60 hours a week.
B.people were busy before Christmas
C.the stranger brought over the bike
D.life was hard for the young family.

How did people get to know the couple’s problem?

A.From radio broadcasts. B.From a newspaper.
C.From TV news. D.From a stranger.

What do the couple learn from their experience?

A.Strangers are usually of little help.
B.One should take care of their bike.
C.News reports make people famous.
D.An act of kindness can mean a lot.
