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 rea son 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 o f 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 |
We have an amazing 99 friends at the age of 21--more than at any other time in our life, according to a new study. The typical 21-year-old’s social circle nearly hits 100, with 13 “best” friends, 17 “close” friends and 70 acquaintances.
The research undertaken by skin care brand Nivea found our social circle peaks at 21 as we meet people at work while keeping in touch with friends from school and university. But as our working lives take over，we lose contact with some old friends causing the number to drop to around 68 by the time we are 29 years old. Although this decline continues into old age，it slows down slightly for people in their 30s when many of them become first-time parents. It is believed that this is because people form new friendships while on the maternity ward(产科病房)，at post-natal(产后) groups and when taking their toddlers(学步时期的小孩) to nursery.
The Nivea Closeness Report found the balance between our numbers of “best friends”，“close friends” and “acquaintances”，remains fairly constant throughout our lifetime. The average Briton has 18 close friends and a friendship circle，when all Facebook and other social networking “friends” are included，of 208 people. The report found that men have more than twice the number of close friends，with around 27 compared to women who have just 12. Londoners are also the most sociable，with 39 “close friends”，while the Welsh have just 11.
The age of 21 is such a critical junction in life and that’s why we have so many friends then. As we get older we become more selective and have fewer close friends with whom we talk about the things that are really important to us. Perhaps when we are younger，instead of having one trusted confidante(知己) we share different things with a variety of different people.According to the Nivea Closeness Report，who have the largest number of close friends?
| A．Canadians. | B．The Welsh. |
| C．Londoners. | D．Americans. |
Older people have fewer friends than the 21-year-olds because .
| A．they think friends are no longer important |
| B．they are more selective and cautious |
| C．they are less interested in making friends |
| D．they have little time to make friends |
The research suggests that the number of friends in one’s late twenties reduces by or so, compared to that in one’s early twenties.
| A．70 | B．20 | C．30 | D．200 |
Why does the number of one’s friends decrease slowly when he is about 30 years old?
| A．Because they achieve success in business and get acquainted with more colleagues. |
| B．Because many parents make friends with people who have similar experiences in bringing up children . |
| C．Because they make more friends through Facebook or the Internet. |
| D．Because as they grow older, they have more confidantes instead of acquaintances. |

A group of 1309 passengers boarded the MS Balmoral on Sunday, in Southampton, England, on a voyage to retrace(重走) the path of the Titanic. The Titanic was the biggest ship in the world when it sailed on its ill-fated first voyage on April 10, 1912. Of the 2227 passengers and crew aboard, more than1500 died. The ship, which was headed for New York City, carried the rich and famous on its first voyage. It also carried immigrants who were seeking a better life in America.
Relatives of people who sailed on the Titanic, historians, authors and people fascinated by the story of the unsinkable ship were on the Balmoral. They wanted to remember the Titanic and those who died on her first and last voyage.
The Balmoral is following Titanic's original route from Southampton. First, the modern-day cruise liner docked（进港） in the port of Cherbourg, France, where the Titanic had picked up more passengers. On Monday afternoon, the Balmoral stops in Cobh, Ireland, the Titanic's last port of call before sailing to New York.
The Balmoral then sailed the North Atlantic Ocean to the location where Titanic hit an iceberg . On Sunday, April 15, at 2：20 a. m. --- the time the Titanic went down---passengers and crew held a memorial service. The next two days were spent in Halifax, Canada, where many victims of the sinking are buried. Then, the Balmoral will reach its final destination in New York City, where Titanic was supposed to dock—but never did.
So far, several teams of divers have explored the site. They have recovered some items such as dishes and silverware and put them on public display. And more trips are planned to the wreckage in the future. The Titanic and its passengers and crew have been remembered in books, movies and TV programs. But there's a much more important contribution that Titanic gave us. After she sank, lawmakers and shipbuilders made ships safer. It took a terrible tragedy to make ship travel safer for all.We learn from the first paragraph that .
| A．about 700 passengers of the Titanic survived. |
| B．the Titanic sank on its second voyage. |
| C．less than 2000 passengers boarded the Titanic. |
| D．all the passengers’ hopes of the Titanic lay in America. |
Which of the following shows the correct route of the Balmoral?
a. Halifax b. New York City c. Cobh d. Southampton e. Cherbourg
| A．e-d-a-b-c | B．d-e-c-a-b |
| C．e-c-a-b-d | D．d-c-e-a-b |
What might be the most important contribution of the Titanic?
| A．Its site attracts more exploring teams. |
| B．It makes the later ships more secure. |
| C．Some of its items are on public display. |
| D．More trips are planned to its wreckage. |
In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decade has seen more and more forests disappearing and the globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the healthy while using its supply of natural resources.
Today, sustainable development is a popular trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decade. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy resolution. It is now trying hard to made full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil(棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown more than 50%.
Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions(排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge public expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from the traditional model to a sustainable one.
The major challenge of this century is to find ways to meet the needs of a growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.The traditional business model is harmful because of all the following EXCEPT that____.
| A．it makes the world warmer |
| B．it consumes natural resources |
| C．it brings severe damage to future |
| D．it makes growth hard to continue |
What can we infer from Paragraph2?
| A．China lacks wind and solar energy. |
| B．China is the leader of the low-carbon market. |
| C．High-speed trains are a low-carbon development. |
| D．Palm oil is made at the cost of valuable forests. |
To fully develop the low-carbon markets governments can______.
| A．cut public expenses |
| B．forbid carbon emissions |
| C．develop public resources |
| D．encourage energy conservation |
We can learn from the last paragraph that businesses have many chances to _______.
| A．develop sustainable products |
| B．explore new natural resources |
| C．make full use of natural resources |

In the fall of 1985, I was a bright-eyed girl heading off to Howard University, aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere. Twenty-one years later I am still a bright-eyed dreamer and one with quite a different tale to tell.
My grandma, an amazing woman, graduated from college at the age of 65. She was the first in our family to reach that goal. But one year after I started college, she developed cancer. I made the choice to withdraw from college to care for her. It meant that school and my personal dream would have to wait.
Then I got married with another dream: building my family with a combination of adopted and biological children. In 1999, we adopted our first son. To lay eyes on him was fantastic---and very emotional. A year later came our second adopted boy. Then followed son No. 3. In 2003, I gave birth to another boy.
You can imagine how fully occupied I became, raising four boys under the age of 8. Our home was a complete zoo---a joyous zoo. Not surprising, I never did make it back to college full-time. But I never gave up on the dream either. I had only one choice: to find a way. That meant taking as few as one class each semester.
The hardest part was feeling guilty about the time I spent away from the boys. They often wanted me to stay home with them. There certainly were times I wanted to quit, but I knew I should set an example for them to follow through the rest of their lives.
In 2007, I graduated from the University of North Carolina. It took me over 21 years to get my college degree！
