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

After battling hard times and danger for over nine months, British teenager Mike Perham made history last month as the youngest person to sail solo around the world.
The 17-year-old made the record after he cleared the Panama Canal and then sailed through the Caribbean and got home across the Atlantic.
Mike is only three months younger than Zac Sunderland, the 17-year-old American boy who had taken the crown as the youngest solo around-the-world sailor in July.
The two youngsters met in Cape Town in South Africa as they crossed the globe in different directions. Mike insisted they were not rivals(竞争对手). “No. It's two teenagers going out there, living their dream and having the adventure of a lifetime,” he said.
Mike may be young, but he is no stranger to sailing adventures. He picked up the hobby at the age of 6 when his father took him out in a small boat on a local lake. Father and son sailed separate boats across the Atlantic when Mike was 14, making him the youngest person to cross that ocean solo. That record gave him the taste for this even greater challenge.
On the recent journey, the scariest moment for Mike came when his sailboat was hit by storms in the southern Indian Ocean.
“We were picked up by what felt like a 60-foot wave and threw down on our side at 90 degrees,” he said.
“It felt like I was going right over. Stuff was flying around and I just thought ‘Oh no’.”
At other times, he had to dive into the Pacific and fix problems. He tied himself to the boat, jumped into the water and went to work with a knife in 30-second dives underneath the boat to cut a rope away.
Mike said he felt proud that he made his dream come true. “You've got to have confidence in yourself that you will make it,” he said.. What's the main idea of the passage?
| A．A British teenager became the youngest person to sail solo around the world. |

Mr. Peter Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route — through the boot (行李箱).
Mr. Johnson’s car had finished up in a ditch at Romney Marsin Kent after skidding on ice and hitting a bank. “Fortunately, the water began to come in only slowly,” Mr. Johnson said. “I couldn’t force the doors open because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in.”
Mr. Johnson, a sweet salesman of Sitting Home Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape.
Later he said, “It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came.”
It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench and began to work on the boot lock. Fifteen minutes passed by. “It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled clear as the car filled up.”
His hands and arms cut and bruised (擦伤), Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer’s wife, Mrs. Lucy Bates. Huddled in a blanket, he said, “That thirty minutes seemed like hours.” Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch. Which of the following objects is the most important to Mr. Johnson?
| A．The hammer. | B．The coin. |
| C．The screw. | D．The horn. |
Which statement is true according to the passage?
| A．Mr. Johnson’s car stood on its boot as it fell down. |

| D．Mr. Johnson struggled in the pouring mud as he unscrewed the back seat. |
“Finally it gave” (Paragraph 5) means that _________.
| A．Luckily the door was torn away in the end |
| B．At last the wrench went broken |
| C．The lock came open after all his efforts |

Drawings of human colonies on other planets often picture the entire community under a glass or plastic bubble. The bubble is intended to create an atmosphere with adequate oxygen and other essential elements. But similar bubble-like structures have also been constructed on earth. One of the most famous, and controversial, is a site in the Arizona desert.
Biosphere 2, as it is called, was built not far from Tucson in 1984 and is now run by Columbia University. This huge（7,200,000-cubic-foot）glass and steel construction contains several separate ecosystems, including a desert, a rain forest, and a 900,000-gallon “ocean.” The climatic conditions-humidity, temperature, air quality-are regulated by sensors and can be adjusted as needed or desired. For example, a rainstorm can be created to increase the humidity. The adjustable features of Biosphere 2 make it an ideal location to perform experiments to help determine the effects of such climatic changes as global warming.
The current conditions at Biosphere 2 are vastly different from those in 1993, when eight people who had moved into the environment with great fanfare two years earlier moved out in failure. Though promising to be self-sufficient（自足的）, these “colonists” had so much trouble regulating the environment that they reportedly had food smuggled into them. Oxygen levels became dangerously low; most plants and animals died. In taking over the unsuccessful site, Columbia hopes to erase its notorious past by focusing on small research projects that gradually answer some of Biosphere 1’s — that is, Earth’s most basic environment questions.This passage primarily deals with _________.
| A．conditions of life in Biosphere 2 |
| B．building controlled environments on other planets |
| C．why Biosphere 2 failed in the past |
| D．what makes a good biosphere colonist |
Biosphere 2 is now run by _________.
| A．a group of eight colonists |
| B．Columbia University |
| C．the city of Tucson |
| D．scientists who hope to establish Biosphere 3 |
The passage suggests that earlier colonists of Biosphere 2 _________.
| A．did not like living in a controlled environment |
| B．found it very difficult to live in a controlled environment |
| C．still are involved with Biosphere 2 |
| D．have now left the country in disgrace |
The writer helps you understand what Biosphere 2 is like by _________.
| A．comparing its features with those of an outer space biosphere |
| B．explaining the process by which it was constructed |

| A．well known for something good | B．well known for something bad |
| C．very dangerous | D．quite interesting |
Making an apology is not the same as making amends. Sometimes we apologize just because it’s the easiest thing to do. What’s actually important is to identify where we go wrong, take full responsibility for our mistakes and , if possible, try to make up for them.
A recent case involving Hewlett-Packed, the US computer giant, shows the importance of presenting a sincere apology. The Chinese consumers who had bought notebook computers of certain models, which have been put on Chinese market since 2007, suffered a massive flash screen failures and overheating problems. Through investigation, Chinese AQSIQ (国家质检总局) identified these HP computers had quality problems and HP admitted this. HP made a proposal that they would extend the warranty (保修) period of such computers, but this could not satisfied the consumers. What they needed was a thorough description of the truth. HP has “sincerely” apologized. But the consumers remain angry, and say that only a product recall — as HP has done in the past — will prove that the apology is sincere.
Another apology that fell flat on its face was that of Thierry Henry, the famous French footballer. His deliberate handball in November 2009 created the goal which knocked Ireland out of the 2010 World Cup. The incident caused great anger in the football world, and eventually Henry issued an apology. Two days later, he wrote, “I’m not the referee…but if I hurt someone I’m sorry.” Better late than never, perhaps, but even then he passed the blame onto the referee!
Such high-profile cases, which attract a lot of publicity often under the spotlight, but similar incidents occur in our everyday lives. Stress caused by schoolwork and tiredness can sometimes result in outbursts of anger against friends and family. Have you ever lost your temper for minor reasons? After calming down, most people are quick to realize their mistake and apologize. But it’s just as important to identify what caused the error in the first place and take action to ensure it doesn’t happen again.
No one should hold a negative attitude to making a sincere apology. Empty words are easy to say, but they are as useless as they sound. A real show of remorse（痛悔;自责）demands hard work and commitment to put error right.What does the author intend to tell us in the case of HP?
| A．A true apology needs sincere actions. |
| B．HP should recall all the faulty computers. |
| C．Good quality makes a good company. |
| D．A company should apologize and pay for their mistakes. |
According to the author, when we do anything wrong we firstly _________.
| A．make an apology face to face honestly |
| B．admit we were wrong and try to make the wrong right |
| C．take the responsibility for apologizing to others |
| D．choose the easiest thing to do |
We can infer from the case of Thierry Henry that _________ .
| A．it’s never too late to say “I’m sorry.” |
| B．writing an apology is not a good idea |
| C．Henry didn’t identify his fault. |
| D．the football fans were mad with Henry. |
Which of the following can best explain the word “commitment” in the last paragraph?
| A．Decision. | B．Promise. | C．Agreement. | D．Responsibility. |
What’s the best title of this passage?
| A．What really puts things right |
| B．Don’t apologize easily |
| C．Making an apology — no one is out of exception |
| D．How to judge an apology — sincere enough? |
The idea about the phoenix goes back to Ancient Egypt, where we find the phoenix described as a handsome, eagle-like bird, with part-golden, part-red plumage, that spent most of its life in the Arabian deserts. It was rarely seen and according to one version of the story, only appeared in Egypt once every five hundred years, when it flew to Heliopolis, “city of the sun”, and deliberately burnt itself to ashes by settling on the altar (祭坛) flame there! However, it seems it did not really die because from those same ashes a young, fully formed phoenix was born and flew away, apparently back to Arabia.
It is pretty obvious that no one has ever seen or will see a living phoenix. The interesting thing is that we can find certain clues which may explain one aspect of the Egyptians’ idea. It may sound unbelievable, but some birds are apparently quite charmed by flames and small fires, especially members of the crow family. One zoologist actually proved this by setting fire to some straw near to a tame（驯养的）rook, a large black bird like a crow. Far from becoming nervous and backing away, the bird deliberately stood over the flames, with raised and vibrating wings. It didn’t get burnt, but the image it presented by its strange behavior was almost exactly like that shown in illustrations of the mythical phoenix!
Why birds should occasionally behave in this strange way is not clear. One idea is that they carefully use the heat of the flames to relieve the annoyance caused by their feather mites (虱) which all birds have. Whatever the reason, it is quite possible that the Ancient Egyptians saw birds behaving in this way, from time to time, and used it as the basis of their phoenix myth, adding fanciful details which closely linked it to their worship of the sun and their belief in resurrection.
Nowadays, the phoenix is much less important to us than it was to the Egyptians. But the logo of modern fire insurance companies, which employ the phoenix as one of their symbols, refers that in one sense the idea of it remains. According to the passage, the phoenix _________ .
| A．is a handsome and eagle-like bird living in Arab |
| B．used to be seen when the Egyptians held religious activities |
| C．has never really existed in the world |
| D．is the king of all kinds of birds |
The reason why birds stand above flames is probably that _________ .
| A．the phoenix used to do so | B．they may get rid of the mites |
| C．they want to burn their feather | D．they can heat themselves |
Which of the following statements is NOT correct?
| A．The ancient Egyptians worshiped the phoenix. |
| B．The scientists have discovered why birds are attracted by fire. |
| C．The modern people still favor the idea of the phoenix. |
| D．The mythical tales about the phoenix were based on facts. |
Which of the following is closest to the underlined word “resurrection” in the 3rd paragraph?
| A．living forever | B．offering warmth |
| C．coming back to life | D．staying healthy |
What does the phoenix probably mean in the logo of a fire insurance company?
| A．Our company can protect you from being harmed by fire. |
| B．If your property is destroyed by fire, we will help you build it up again. |
| C．Our company will always be energetic and wealthy. |
| D．If needed, we will save you at the risk of losing lives. |
