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 latest 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 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 |
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 |
Eco City Farms are becoming more popular in cities and towns around the United States.
Eco City Farms in Edmonston,Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a workingclass community. People do not have very much money, and they have limited access to fresh food in markets.
Over the past two years, the farm has attracted volunteers from the community like Marcy Clark. She schools her four children at home. On a recent day she brought them to Eco City Farms for a lesson. Her son Alston Clark thinks his experience is very valuable. “I like coming out here，” he says, “You know, you connect with the earth, where your food comes from. You appreciate the food a little bit more.”
Margaret Morgan started Eco City Farms. She thinks of it as a place where people can learn to live healthier lives. “Growing food in a community brings people together，” she continues, “Every piece of what we do here is a demonstration to show people everything about how to have an ecofriendly community.” she says. From the Eco City Farms people come to know that they are not only growing food and raising chickens and bees, but improving the soil with compost (肥料) made from food waste.
Eco City Farms is an experimental operation. The farm gets its power not from the local electricity networks, but from the sun with solar panels. In winter, the green houses use a geothermal (地热) system.
Vegetables can be grown all year. So once a week, all winter long, neighbors like Chris Moss and her three children bike to the farm to pick up a share of the harvest.

The way people hold to the belief that a fun-filled, and pain-free life equals happiness actually reduces their chances of ever attaining real happiness. If fun and pleasure are equal to happiness then pain must be equal to unhappiness. But in fact, the opposite is true: more often than not things that lead to happiness involve some pain.
As a result, many people avoid the very attempts that are the source of true happiness. They fear the pain inevitably(不可避免的) brought by such things as marriage, raising children, professional achievement, religious commitment (义务), self - improvement.
Ask a bachelor(单身汉) why he resists marriage even though he finds dating to be less and less satisfying. If he is honest he will tell you that he is afraid of making a commitment. For commitment is in fact quite painful. The single life is filled with fun, adventure, excitement. Marriage has such moments, but they are not its most distinguishing features.
Couples with infant children are lucky to get a whole night’s sleep or a three - day vacation. I don’t know any parent who would choose the word fun to describe raising children. But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild.
Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations. It liberates time: now we can devote more hours to activities that can genuinely increase our happiness. It liberates （解放）money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless. And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all.According to the author, a bachelor resists marriage chiefly because _______ .
| A．he is reluctant to take on family responsibilities |
| B．he believes that life will be more cheerful if he remains single |
| C．he finds more fun in dating than in marriage |
| D．he fears it will put an end to all his fun adventure and excitement |
From the last paragraph, we learn that envy sometimes stems from ________ .
| A．hatred | B．misunderstanding |
| C．prejudice | D．ignorance |
What is the author trying to tell us?
| A．Happiness often goes hand in hand with pain. |
| B．One must know how to attain happiness. |
| C．It is important to make commitments. |
| D．It is pain that leads to happiness. |
When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo’s parents set out to prove the doctors wrong.
The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren’t interested in supporting research into such a rare disease.
However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial and error, they finally created a cure from ingredients (调料) commonly found in the kitchen. The cure, named "Lorenzo’s Oil", saved the boy’s life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it.
Finally, the boy’s father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy.Doctors said that Lorenzo might die within three years because_____ .

Do you know how to use a mobile phone without being rude to the people around you?
Talking during a performance irritates (激怒) people. If you are expecting an emergency call, sit near the exit doors and set your phone to vibrate (振动). When your mobile phone vibrates, you can leave quietly and let the others enjoy the performance.
Think twice before using mobile phones in elevators, museums, churches or other indoor public places—especially enclosed spaces. Would you want to listen to someone’s conversation in these places? Worse yet, how would you feel if a mobile phone rang suddenly during a funeral! It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off.
When eating at a restaurant with friends, don’t place your mobile phone on the table. This conveys the message that your phone calls are more important than those around you.
Mobile phones have sensitive microphones that allow you to speak at the volume you would on a regular phone. This enables you to speak quietly so that others won’t hear the details of your conversations. If you are calling from a noisy area, use your hand to direct your voice into the microphone.

Advertising gives useful information about which products to buy. But modern advertising does more than gives news about products and services. Today’s advertisements, or ads, try to get consumers to buy certain brands. Writers of advertising are so skillful that they can, sometimes persuade a consumer to wear a certain kind of clothing, eat a special kind of cereal, or see a movie. Consumers might never even want a product if they did not see or hear advertisements for it.
For example, you probab1y do not need the newest cereal in the supermarket. There are probably many cereal brands on your kitchen shelves. You may not have space on a shelf for another. But if you see ads about a new cereal that is your extra-tasty and has a free prize in the box, you may want it.
Advertising must get attention. To be effective, it must be exciting, entertaining, or provide some pleasure. The secret of writing good advertising copy is to offer a good idea as well as a product. The idea is what the ad is really selling. One example is an ad that says eating a certain cereal will make a person do well in sports.
