Word came that the government must control the spread of this disease.

“Our job，”said the　26　officer，“is to spray the wall of every house in every town and village in the malaria parts of Mexico.You may be　27　to learn that there are about ninety-nine thousand　28　villages and towns.Some are big places like the capital city，　29　are single houses deep in the forest or upon the mountaintops.The men working with our program say that most of these people　30　within districts which are　31　enough for the mala ria-carrying mosquitoes to live in and spread the disease.That　32　that we must plan to spray the bricks of　33　three million houses once or twice a year for five years.”

“We have　34　everything very carefully，”said the officer　35　.“Our advance guards have drawn　36　of some forty thousand parts of the country for　37　by the spray teams.Each house in the malaria districts has been given a special　38　so that we can work in order.The United States has given us cars and trucks to carry the spray teams and their　39　.”

“The malaria program has been　40　with the people in this country.Everyone wants to　41　.The Defense Department is helping us plan the　42　of men and supplies.The Education Department has printed sheets in Spanish to explain　43　malaria is spread.Resistance is a problem.It was in the neighboring country—the United States that such resistance to spray was first　44　.Take the　45　of the housefly and D.D.T. At fist D.D.T. killed them off.Now it won’t hurt a fly.”

“What worries people is the danger that the mosquitoes may become resistant，”said the officer at last.

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.
【小题1】 The underlined word “longevity” in the second paragraph probably refers to “________”.

What made Joan Ryan decide to be a sports writer?“Ten years ago, I was ?　36　? news stories at the Orlando Sentinel in Florida—my first job ?　37　? college. I didn't know any female sports writers. But I wanted to be ?　38　?.?　39　?,the best writing in the paper was sports.”

One guy was sitting on a bench in front of me, tapping up his ankle,?　53　? a long-handled razor for cutting the tape. Suddenly, I felt something move up my leg. It was the ?　54　? of the razor. I yelled at him and walked out.”

Joan ?　55　? interviewing Cribbs—outside the locker room.“In retrospect(回忆),I feel this was a defining moment for me as a journalist. I went back and wrote my story and made my deadline. Now I know that nothing can interfere with getting the story.”?
