  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 aging 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 aging 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.

(1)The underlined word“longevity”in the second paragraph probably refers to _______.

[  ]

A.health
B.long life
C.aging
D.effect

(2)The text mainly talks about ________.

[  ]

(3)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

(4)If you want to live longer, you should __________.

[  ]

A.enable your heart to beat much faster

B.find out the reason for aging

C.exercise regularly to keep your heart healthy

D.prevent your cells from being lost

(5)We can know from the passage that _________.

[  ]

A.the reason why aging 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

The weather has always been a popular topic in our daily life. But it is sometimes no one can control, 1 he is rich or poor ,young or old in every 2 of the world. Maybe that is the 3 why there are so many 4 about the weather, especially about rain.

Sometimes, when you 5 rain, you do not get any . Other times, you 6 rain when you don’t want it . 7 a baseball game, for example. A sudden rainstorm can stop an exciting game, 8 the players and the 20,000 persons watching the game to run for 9 .

If the game 10 continue, people who bought tickets are given “rain checks”. These are 11 tickets that will let them see a 12 game for free.

“Rain Check” now means a second 13 at something. Often ,a rain check has nothing to 14 with rain.

Stores may offer “rain checks “ 15 they sell out all of a product a television set , for example 16 a special low price. After all the TV sets are 17 , the store gives rain checks to 18 who wanted to buy one. The rain check allows a person to buy the TV set later, at the 19 low price, after the store receives some 20 from the factory.

“Rain Check”also is used in social 21 .It’s a way of 22 aninvitation, but for a later time.

You may ask for a “Rain Check” if you are 23 to a friend’s house for dinner, but can’t be there. You say ,“I would love to 24 you for dinner, but I’m busy. Could I have a rain check?”You are asking , in other 25 ,if you could join your friend for dinner at another time.
