because of the many changes in computer technology, laptop use in higher education, such as colleges and universities is workable.as laptops become more powerful, they become more similar to desktop computers.in addition, the portable computers can connect students to not only the internet, but also libraries and other resources.state higher-education officials are studying how laptops can help students.state officials also are testing laptop programs at other universities, too.
at westlake college, more than 60 percent of the staff use computers.the laptops will allow all teachers to use computers in their lessons.as one westlake teacher said, “here we are in the middle of virginia and we’re giving students a window on the world.they can see everything and do everything.”

as the proverb says, “no one knows the value of health until he loses it.”in other words, nothing is more valuable than health.
it is clear that health is the foundation(基础) of one’s future success.if you become sick, it is scarcely possible to pursue(从事) your career effectively, much less make your dreams come true.on the other hand, if you are strong, you can go all out to overcome the obstacles(障碍) that lie ahead of you.
health is the resource of our energy.what should we do to maintain(保持) our health?first we should exercise every day to strengthen our muscles.second, we might as well keep good hours.if we get up early, we can breathe fresh air and see the sunrise.this habit can do wonders for our outlook on life.third, there is a proverb that says, “prevention is better than cure.”if you pay close attention to your health, you can avoid getting sick, or at least cure yourself of a disease while it is still in its beginning stage.
in conclusion, health is more important than wealth.those who are rich but poor in health are no more fortunate than those who are poor, and healthy in body.if you want your wish to come true, health is the most important component(组成部分) of your success.

in the 1960s, medical researchers thomas holmes and richard rahe developed a checklist of stressful (有压力的) events.they found out that any major change could be stressful.negative events like“serious illness of a family member”were high on the list, but so were some positive life-changing events, like marriage.when you take the holmes-rahe test you must remember that the score does not show how you deal with stress-it only shows how much you have to deal with.and we now know that the way you deal with these events has a great effect on your chances of staying healthy.
by the early 1970s, hundreds of similar studies had followed holmes and rahe.and millions of americans who work and live under stress worried over the reports.somehow, the research got boiled down to a memorable message.women’s magazines ran headlines like“stress causes illness!”if you want to stay physically and mentally healthy, the articles said, avoid stressful events.but such simplistic advice is impossible to follow.even if stressful events are dangerous, many-like the death of a loved one is impossible to avoid.moreover, any warning to avoid all stressful events is a prescription(处方) for staying away from opportunities as well as trouble.since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move.
the idea that all stress makes you sick also takes no notice of what we know about people.it is supposed that we’re all weak and passive in the face of difficulty.but many come through periods of stress with more physical and mental strength than they had before .we also know that a long time without change or challenge can lead to boredom and physical and mental damage.
55.the studies on stress in the early 1970’s led to __________.
a.wide spread worry over its harmful effects
b.great fear about the mental problems it could cause
c.a deep research into illnesses connected with stress
d.popular avoidance of stressful jobs
56.according to the passage people who have experienced ups and downs may become __________.
a.discouraged when faced with difficulty
b.physically and mentally weak
c.more experienced in the face of difficulty
d.uninterested in what happens to them
57.what’s the purpose of writing the text?
a.to tell people the discoveries about stress.
b.to tell people how to keep healthy.
c.to help people avoid stressful events.
d.to help people view stress properly.

i’m gwen outen with the voa special english development report.
a few years ago, researchers discovered a simple answer to a big problem.they found that the bacteria that causes cholera can be removed from drinking water with simple cloth filters.pouring water from rivers or lakes through several thicknesses of cloth can trap tiny organisms like the cholera bacteria.
a three-year study took place in bangladesh.american and bangladeshi scientists went to 65 small villages in a country where cholera is a major health problem.they tested the use of saris as cloth filters.a sari is the traditional clothing worn by most women in bangladesh.
people in one group of villages used cloth from old saris, folded eight times, as a filter for their drinking water.people in another group of villages used modern nylon filters for their water.people in the other villages continued to gather water in traditional ways, without using filters.about 44 000 people were studied in each of the three groups of villages.
rita colwell from the university of maryland at college park helped lead the study.she said the people in the villages using filters from old saris had the lowest number of cases of cholera.the researchers also found that almost 99 percent of cholera bacteria could be filtered out with the sari cloth.rita colwell said cloth from old saris worked best because it has been washed repeatedly.she said the space between the threads of the material narrows when the cloth is washed, so it traps smaller particles.
cholera is an intestinal(肠道, 肠内物, 侵袭肠的) infection that can develop in the body in less than five days.it can quickly lead to severe loss of fluids through diarrhea（腹泻）  and vomiting（呕吐）.cholera can cause death if treatment is not given quickly.children under age five are most at risk.
people get the disease by drinking water or eating food that contains the bacteria.the disease is most often found in areas where there is unclean water and poor systems for treating human waste.
the most recent yearly report on cholera on the web site of the world health organization is for two thousand two.that year, 52 countries reported a total of 142 000 cases.these infections resulted in more than 4500 deaths.
this voa special english development report was written by jill moss.i’m gwen outen.
58.this passage is a __________.
a.a letter
b.a news report
c.a statement
d.an announcement
59.what does the underlined word sari in paragraph 3 mean?
a.a kind of cloth
b.a hatc.sars
d.an outer garment
60.which one of the following is true?
a.american and some african scientists went to 65 small villages to test the use of saris.
b.there are less than 4 400 people in these villages.
c.cholera is an intestinal infection that can bring about fever and vomiting.
d.the disease is most often found in areas where there is dirty water and poor systems for treating human waste.
