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 hardly 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 (性别)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

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

Why do men live a shorter life than women? The latest research indicates that men’s hearts going into a rapid decline when they reach middle age could be the cause.
The research of ageing on the heart has shown that women’s longevity may be linked to the fact that their hearts do not lose much pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 20 and 70 years of age,” said the head of the study, Samantha of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells which make it beat.Between the ages of 20 and 70, one-third of those cells die and are not replaced in men ,” said Samantha.“This is part of the ageing process.”
What amazes scientists is that the female heart suffers very little loss of these cells.A healthy 70-year-old woman’s heart could work almost as perfectly as a 20-year-old one’s.
“This gender (性别)difference might give the reason why men live shorter than women,”said Samantha.They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease.“The team has yet to think about why ageing suffers a greater loss on the male heart,” said Samantha.
But there is also good news -- men can enjoy the health of their hearts with regular exercise.Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.
【小题1】The underlined word “longevity” in the second paragraph means “________”.

A.healthB.long lifeC.ageingD.effect
【小题2】The text mainly talks about ________.
A.men’s heart cellsB.women’s ageing process

【小题3】According to the text, the UK scientists have known that ________.
A.men have fewer cells than women when they are born
B.women can produce the cells that make the heart beat
C.the female heart suffers less loss of the cells with age
D.women will never suffer the loss of pumping power with age
【小题4】If you want to live a long life, you should ________.
A.enable your heart to beat much faster
B.think about the reason for ageing

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 (无意义的)? 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(证据) more than proves (证明) my points that women are queens of the road. Oh ,men, if you want to continue criticizing (批评) 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.
【小题1】Who does the author think are the better drivers? (no more than 1 word)
_________________________________________________________________________
【小题2】When will women drivers stop to ask for help? (no more than 9 words)
_________________________________________________________________________

【小题4】What quality(品质) do women drivers have when it comes to safety? (no more than 3 words)
