1、The State of Marriage Today
Is there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times and extramarital affairs will be even more common than they are now.
But what are the reasons for this, and is the picture really so gloomy? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands as they usually didn＇t have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don＇t feel that they need to stay in a failing marriage.
In answer to the second question, the outlook may not be as pessimistic as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now cohabit and don＇t bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive. The statistics are deceptive because there is a higher number of divorces in second and third marriages than in first marriages.
So is marriage really an outdated institution? The fact that most people still get married indicates that it isn＇t. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!
Which is true about the problem of marriage in the United States today?【单选题】

A.Divorce leads to the breakup of the family.

B.Half of the married couples get divorced.

C.American people marry more than four times.

D.More and more people are getting divorced.

正确答案:D

答案解析:从第1段里可以了解到选项A与C都是预计将来会发生的，而不是如今的情况。B选项与第1段第2句“almost 50% of the marriages end in divorce”不符。第1段第2句里的“the rate of divorce in the United States has exploded”、“the evidence suggests it is going to get worse”正好说明了D选项的情况。

2、Electric Backpack
Backpacks are convenient. They can hold your books, your lunch, and a change of clothes, leaving your hands free to do other things. Someday, if you don＇t mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.
Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass, have invented a backpack that makes electricity from energy produced while its wearer walks. In military actions, search-and-rescue operations, and scientific field studies, people rely increasingly on cell phones, global positioning system (GPS) receivers, night-vision goggles, and other battery-powered devices to get around and do their work. The backpack＇s electricity-generating feature could dramatically reduce the amount of a wearer＇s load now devoted to spare batteries, report Rome and his colleagues in the Sept. 9, Science.
The backpack＇s electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer＇s back, and the whole pack moves up and down as the person walks. A gear mechanism converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7. 4 watts.
Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack＇s oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.
The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren＇t on the market yet, but if you do get one eventually, just make sure to look both ways before crossing the street!

3、Human Space Exploration
While scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 and respond quickly to space station emergencies.
The space agency released the first set of mission needs and requirements several days ago for me orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to and from the International Space Station.
Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper and require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available for rescue missions by 2010. NASA says the craft should be able to transport injured or ill space station crew members to "definitive(决定性的) medical care" within 24 hours.
The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia and its seven member crew on February l, 2003.
Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working for years on a successor to the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.
The program＇s managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster.
U. S. President George W. Bush asked Congress for about US$1 billion for Space Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane and Next Generation Launch Technology.
Besides its main mission, the orbiter would also be used as .【单选题】

A.a medical research center

B.a space station

C.a space ambulance

D.a passenger plane

正确答案:C

答案解析:此题与第41题相连，问除了运送航天员这一主要使命外，航天飞机还用来干什么？原文第1句也回答了这个问题，那就是把它作为太空急救车，故C为正确答案。

4、Stop Eating Too much
"Clean your plate!"and" Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent or grandparent. Often, it＇s accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of saying "clean the plate", perhaps we should save some food for tomorrow.
According to news reports, US restaurants are partly to blame for the growing bellies(肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.
Barbara Rolls, a nutrition (营养) professor at Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline(腰围) began to expand.
Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can＇t afford fine dining still prefer large portions. Seventy percent of those earn at least $ 150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25, 000 want smaller.
It＇s not that working class Americans don＇t want to eat healthy. It＇s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money for next year＇s Christmas presents.(2008年)
