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 aging 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.The underlined word “longevity” in the second paragraph probably refers to ______.
| A．health | B．long life | C．aging | D．effect |
The text mainly talks about ______.
| A．men’s heart cells | B．women’s aging process |

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 aging |
| 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 aging 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 |

People think what I do is so wonderful because I interview stars.And I have to admit that when I first started working at Sassy in 1987 I was excited about that part of my job for the first couple of months，anyway.Then I noticed how stars would fool me around for months.I could never get enough time with a star to find out anything interesting，and some acted just simply rudely.I started hating the way I was treated，and I was really disappointed to see that these people I had worshipped (崇拜) before were pretty ordinary.So I decided I would just tell the truth instead of keeping up their myths (神秘)．If the star was a bad guy，I would say so.If I thought anyone was stupid，I did not hold back that information.
I thought readers would appreciate that kind of honesty.Surprisingly，many of them hated me for it.I have gotten so many attacks on my character.In their eyes，being famous is everything，even more desirable that being truly creative and talented.
Why do we need stars？In fact，the media created stars to satisfy our basic need for gossip (闲聊)．Over time，talking about people we have never met and we are never likely to meet has become what we are crazy about.Thus，some people are more interested in the personal lives of the stars than in the lives of their own family and their own friends.That is why it is so ridiculous when a star wants to discuss only his or her work in an interview—as we care.We want the dirt on their personal lives.
There is another reason we worship stars.As a whole，our society is not as religious as it once was.It seems that people need something to fulfill them the way religion once did.Star worship exists as an unfulfilling desire for true heroes.
We make them stars，but then their reputation makes us feel unimportant，and we truly feel better about ourselves when they die.I am part of this whole process.No wonder I feel soiled at the end of workday.What are the stars like according to the author?
| A．They always treat others rudely. |
| B．They always talk about something dull. |
| C．They are actually ordinary people. |
| D．They are usually honest and polite. |
We worship stars because ________.
| A．we need true mental heroes to support us |
| B．we can learn something useful from famous stars |
| C．we concern about the stars，family and friends |
| D．we like talking about the star's dressing styles |
When the author is writing this article，his tone sounds ________.
| A．excited | B．angry |
| C．worried | D．calm |
What is the main purpose of the author writing the passage?
| A．To show the disadvantages of working with stars. |

Bad teeth can be painful and even be deadly. Infections of the gums(牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉质), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.According to the passage，what is the function of fluoride?
| A．Making the surface on teeth much cleaner. |
| B．Protecting gums from being infected. |
| C．Keeping holes on teeth from forming. |
| D．Slowing down bacterial growth and acid production. |
The underlined phrase “interfere with” in Para.5 probably means “________”．
| A．do harm to | B．account for |
| C．contribute to | D．stand for |
What is the purpose of the author in writing the passage?
| A．To warn us of the deadly infections of gums and teeth. |
| B．To introduce the advantages of fluoridated toothpaste. |
| C．To draw our attention to the dental care of young children. |
| D．To present the research results about dental care. |
No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.
Let's take a man we'll call Mr. Fielder, for example. He did everything connected with farming. He planted seeds, tended the fields, and harvested and sold his crops. At the same time, he did many other jobs on the farm. However, he didn't make the bricks for his house, cut his trees into boards, make the plows(犁), or any of the other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.
Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in making really good plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows.
How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows.
Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay, or wood symbols for the products they had for sale.
A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people's attention.
A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such a person to spread the news about their products. Often this earliest form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today's world.What probably led to the start of advertising?
| A．The discovery of iron. |
| B．The specialization of labor. |
| C．The appearance of new jobs. |
| D．The development of farming techniques. |
To advertise his plows, Mr. Plowright ________.
| A．praised his plows in public |
| B．placed a sign outside the shop |
| C．hung an arrow pointing to the shop |
| D．showed his products to the customers |
The writer makes up the two stories of Mr. Fielder and Mr. Plowright in order to ________.
| A．explain the origin of advertising |
| B．predict the future of advertising |
| C．expose problems in advertising |
| D．provide suggestions for advertising |
In ancient Egypt, a crier was probably someone who ________.
| A．owned a ship |
| B．had the loudest voice |

When I was young I wanted to be a model，so when a national contest was staged，I convinced my parents to take me for an audition (试演)．I was selected and told I had potential.They said that for only $900 I could attend a weekend event which dozens of the most prestigious (有声望的) modeling agencies from around the world would attend.At 13，my hopes of fame and fortune clouded all judgement and I begged my parents to let me go.We have never been rich，but they saw my enthusiasm and agreed.
