C
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.
69. The underlined word “l(fā)ongevity” in the second paragraph probably refers to “________”.
A. health          B. long life         C. ageing         D. effect
70. The text mainly talks about ________.
A. men’s heart cells                    B. women’s ageing process
C. the gender difference                D. hearts and long life
71. 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
72. 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

How Women Were Freed From Their Homes
As late as 1800, a woman’s only place was in her home. Women in business were unheard of. No respectable woman would dream of entering what was strictly a “man’s world”. Even if she would, what could she do? Men were sure that no woman could do a job well outside her home. This was a widely accepted idea. When the famous Bronte sisters began writing books in 1846, they had to resort to using men’s names as aliases.
Teaching was the first profession opened to women, soon after 1800. But even that was not easy for women to take because most high schools and colleges were open only to men. Oberlin College in Ohio was the first college in America to take in women.
Nursing was regarded as a respectable profession for women only after Florence Nightingale won high credit for her nursing career and became famous. Miss Nightingale opened the first training school for nursing in 1860 in England.
The invention of typewriters in 1867 helped to bring women out of their homes to join the business world. Because women are careful and have nimble fingers, businessmen found that they were well suited to this kind of work.
By 1890, tens of thousands of women were working in schools, hospitals, shops, offices, and factories both in England and the States. Some even managed to become doctors or lawyers. The idea of women working in business and other circles was accepted.
【小題1】Oberlin College was the first college in America _______.

A.where teaching was a profession only open to women
B.where girls could get advanced education
C.to train women to be teachers and nurses
D.to accept women only as professors and students
【小題2】 It can be inferred from the text that besides nursing, Florence Nightingale was also ______.
A.a doctor B.a lawyerC.a teacherD.a businessman
【小題3】Quite a lot of women entered the business world _______
A.soon after 1800B.when Nightingale became famous
C.at the beginning of this centuryD.after the typewriter came into being

Women make better drivers than men for many reasons. Why is that? Wouldn't you think that competing at who has better driving abilities is pointless (無意義的)? If you ask me, I'd like to say, men know that women are better drivers but do not have the courage to admit the truth.

Unlike men, women stop for directions when they have no idea where they are going. Women don't drive around for hours pointlessly wasting a tank ofgas only to find themselves heading in the wrong direction. Have you ever been in a car with a man who is lost? He tells you to shut up when you begin to open your mouth. And every five minutes or so he takes a turn going forty-five miles per hour only to find out he's made another wrong turn.

Speeding is what men do best on the road. Traffic is not a race. There is a reason why men get more speeding tickets than women. Not because women trick to get out of tickets but only because they don't speed. Women don't risk putting their own lives and the lives of others in danger. In other words,they have more responsibility for life.

My largest issue with male drivers is how a majority of them drive with one hand on the wheel and the other hand doing only God knows what. The seat is backed as far as possible. They're totally lost in loud music beyond a necessary level. You don't ever see women driving like that.

I feel that the above evidence(證據) more than proves (證明) my points that women are queens of the road. Oh ,men, if you want to continue criticizing (批評) women for being bad drivers,bring it on. We know you lack confidence, or else you wouldn't be wasting your valuable time making jokes about the ones you may choose to spend the rest of your days with.

1.Who does the author think are the better drivers? (no more than 1 word)

_________________________________________________________________________

2.When will women drivers stop to ask for help? (no more than 9 words)

_________________________________________________________________________

3.Why do men get more speeding tickets (no more than 3 words)

_________________________________________________________________________

4.What quality(品質) do women drivers have when it comes to safety? (no more than 3 words)

_________________________________________________________________________

5.How is the seat backed by most male drivers? (用完整的句子回答)

________________________________________________________________________

請認真閱讀下面短文,并根據所讀內容在文章后圖表中的空格里填入最恰當的單詞。

When it comes to the prevention of heart disease, women need to pay attention to their own special risks. And so do men. Surprisingly, even children and teens need to be aware- or at least the parents who want to keep them safe do. Thankfully, scientists have also made great leaps in figuring out the specific prevention strategies that work best for all. So now, knowledge is your best protection.

What Men Need to Know

According to the American Heart Association (AHA), at least half of the people who die suddenly from heart disease each year had no clue they were sick. Some think that half of all heart attacks strike out of the blue. Not true, insists Jennifer Mieres, a spokeswoman for the AHA. A 2004 study found that at least 90 percent of first heart attacks are caused by well-known problems like high cholesterol(膽固醇) or diabetes. “If you look closely,” says she, “you’ll almost always find a risk factor that was undiscovered, ignored, or not adequately treated.”

Lifestyle changes like adopting a healthy diet, getting out for regular exercise, avoiding tobacco, losing weight are the first line of defense.

What Women Need to Know

There are some special considerations for the women who are  healthy and want to make sure they stay that way. First, they shouldn't smoke-no one should, but the habit is even harder on women's heart than it is on men's.

Women who find that they are at risk should talk to their doctor about taking a statin(他汀,藥物名). Indeed, statins reduce the risk of heart disease, but there has been not enough evidence that they help high-risk women and it can't guarantee the long-term safety. So it's worth noting that a healthy diet and exercise also reduce cholesterol.

What Parents Need to Know

Last year, a study showed that overweight children and teens have arteries(動脈)that look like those of an average 45-year-old. New guidelines say these children should get a cholesterol test by age ten -- and even urge doctors to consider statins for those most at risk if nothing else works. The recommendations caused oppositions. Lifestyle changes such as diet and exercise are the best strategy, says Dr. Greer, a professor at the University of Wisconsin School of Medicine. Statins should be considered only for kids in danger.
