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 |

If you want to live longer, you should ________.

| C．exercise regularly to keep your heart healthy | D．prevent your cells from being lost |
We can know from the passage that ________.

While reading a book in English, every few lines of text, you run across a word or two that you don’t know. You look up every new word in the dictionary. Bad move. All that does slow you down. Even electric or CD –ROM dictionaries can get in the way of your reading progress. A dictionary is like a road map. It can help you if you get lost and point you in the right direction. But if you stop to look at the “map” each time you take a step, you’ll get nowhere fast.
On your English learning “journey”, a dictionary can be a helpful “travel companion ”--if it is not overused. To help you start thinking in English, use an English-to-English dictionary. Otherwise, you will always depend on your native language and end up translating in your head.
A good dictionary can help you do more than just find the meaning of a word. It can help you verify spelling, check word forms and grammar usage, find example sentence and learn pronunciation. Some dictionaries even provide exercises to teach you how to use their resources.
Take time to get to know your dictionary. Learn the pronunciation symbols. Understand what the abbreviations (缩写字) mean. Try to master the important grammar rules. Look for charts, diagrams and lists that might be useful in the future. You will discover how helpful it can be to make friends with your dictionary. And as they say, “A friend in need is a friend indeed.”Why do we need a good English-to-English dictionary?
| A．Because it is a good friend. |
| B．Because it can help us to find the right direction if we get lost. |
| C．Without it we’ll always depend on our native language and end up translating in our head. |
| D．Because it can help us to start thinking in English and in Chinese. |
The underlined word “that” in the last paragraph refers to __________.
| A．pronunciation symbols and grammar rules |
| B．abbreviations and usage for grammar rules |
| C．the meaning of a word, spelling and grammar usage |
| D．charts, diagrams and lists |
According to the passage, which statement can lead you to believe?
| A．The more you use a dictionary, the better you can understand the article. |
| B．The more you use a dictionary, the faster you may read. |
| C．The more you use the resources in a dictionary, the more you can benefit from it. |
| D．The better a dictionary is, the more expensive it is. |

Dear Sir,
I have to travel every day from Souk Road to the airport． Two buses travel along their route (路线): the number 49 and number 16． But by the time the number 16 bus reaches Souk Road it is always full, so I can’t get on it． I have to wait for the number 49, because sometimes there are empty seats on it．
The timetable says that there are buses from Souk Road to the airport every ten minutes． If this is so, why do I have to wait half an hour for a bus nearly every day?
The regulations say that if there are empty seats on a bus, the bus must stop at every stop where people are waiting． Why do the half-empty buses go straight past me when I am standing at the bus stop?
The regulations say that no bus may carry more than 40 seated passengers and 20 standing passengers． Yesterday I was the first to get off the bus when it reached the airport． I counted the other passengers as they got off． There were 129 of them．
It is clear that our bus companies break the regulations and think little of their passengers． Can nothing be done to make your service better?
