A full night's sleep'/Not everyone needs it. The truism that all adults need at least eight hours of sleep a night for good health should be put to rest by mounting evidence that less may be better.①
People who sleep about seven hours a night live the longest, three huge studies have found, the newest out in the February issue of the journal Sleep. Still, many sleep experts say lots of adults get too little rest, and that can lead to dangerous health problems.
In the latest report from Japanese researchers, 104,010 adults were followed for about 10 years. At the start the participants answered questionnaires about their sleep patterns and about their health mental health and lifestyle. habits, which also can affect survival. After accounting for all of these factors, adults getting all average of seven hours had the lowest death rates. Surprisingly, less sleep ,even as little as four hours a night, didn't significantly increase deaths for men and only lowered survival for women if they averagde less than four hours② But adults who slept longer than seven hours, particulary women, were more likely to die during the 10 years.
Two other major published studies and a dozen smaller ones came to similar conclusions, says psychiatrist Daniel Kripke, a sleep researcher at the University of California-San Diego School of Medicine. Doctors shouldn't tell all of their patients to get at least eight hours of sleep, he says in an editorial in the journal. Hormonal changes triggered by darkness or other unknown biological effects from long sleep could be affecting survival,③ Kripke，says.
But short sleepers may suffer other bad effects. In his brief studies, those sleeping four to five and a half hours did poorly on tests that measure memory, clear thinking and the ability to pay attention, "and they did progressively worse as the week went on," says David Dinges of the University of Pennsylvania School of Medicine. Adults who slept about seven hours performed best, he says. Other small studies have found adults who sleep less than six hours may be at higher risk for some diseases like diabetes and overweight. And sleep deprivation also causes car crashes, Dinges says. "People should get as many hours sleep, p as they need to feel rested," Kripke says, adding that there's no proof that shortening sleep will lengthen life. s1eep need is partly genetic and may be determined by other factors that also influence life span, he says.
What can we learn from the passage？
A．Sleep hours is the most important factor affecting survival.
B．Going to bed and getting up early improve health.
C．Less sleep is more harmful than over sufficient sleep to people.
D．People have different demands of sleep hours.

The phrase "litmus test" is in bad odor for good reason: politicians should be judged on a variety of positions, not just one. But deep down, nearly every voter has at least one litmus test— an issue so personally important that a politician who fails the test is forever tainted, or at least excluded from consideration for the presidency.
I inherited my one litmus test from my father, Jim Alter, who flew 33 harrowing missions over Nazi Germany during World War 11. My father is not just a veteran who by all odds should not have survived. He is a true patriot. His litmus test is the proposal to amend the Constitution to ban flag burning, which will come up for a vote next week in the U. S. Senate. For dad—and me—any member of Congress who supports amending the Bill of Rights for the first time in the history of this country for a nonproblem like flag burning is showing serious disrespect for our Constitution and for the values for which brave Americans gave their lives. Such disrespect is a much more serious threat than the random idiots who once every decade or so try (often unsuccessfully) to burn a flag.
Our understandable outrage at flag burning shouldn't turn our brains to mush. "I feel the same sense of outrage, but I would not amend that great shield of democracy (the Constitution) to hammer a few miscreants," Colin Powell said when the issue last came up (his position has not changed). "The flag will be flying proudly long after they have slunk away." Powell argues that a constitutional ban on flag burning is a sign of weakness and fear.
John Glenn, another of the thousands of combat veterans against the amendment (they have banded together in a group called Veterans Defending the Bill of Rights), notes that "those 10 amendments we call the Bill of Rights have never been changed or altered by one iota, not by one word, not a single time in all of American history. There was not a single change during any of our foreign wars, and not during recessions or depressions or panics. Not a single change when we were going through times of great emotion and anger like the Vietnam era, when flag after flag was burned or desecrated. There is only one way to weaken our nation. The way to weaken our nation would be to erode the freedom that we all share."
Actually, even during the Vietnam War, flag burning was rare. By one count, there have been only 45 such incidents in 200 years, and fewer than half a dozen since it was outlawed in 1989. Should the Constitution be amended, however, the incidence of flag burning is expected to surge as a form. of civil disobedience. What began as a phony issue designed to prove patriotism (usually on the part of those who never served, the primary sponsors) could become a real concern.
The flag-burning amendment, which already passed the House, is apparently just short of the 67 needed in the Senate. With one or two absences, the amendment would be approved. It would then go to the states for ratification, where its chances for approval appear good.
Senators afraid of being seen as soft on flag burners should just adopt the Hillary Clinton dodge: support for a statute, but not an amendment. Another law is a dopey idea (an earlier one was struck down by the Supreme Court), but it's politically safe and better than perverting the Constitution.
To make matters worse, the amendment is vaguely worded, which led to fatuous debate in the Senate over whether a woman wearing a skimpy bathing suit patterned with stars and stripes was guilty of desecration. Bloggers wondered the same thing about President Bush's new habit of autographing flags when he shakes hands on rope lines. Unconstitutional？ With a war on and a hundred other pressing problems, it's nice to see our elected representatives focused on what really counts.
The usual litmus tests-abortion, gun control, Iraq-shouldn't be. Reasonable and sincere people can disagree, w
A．The effectiveness of litmus test is greatly undermined by its failure to judge politicians on a variety of positions.
B．It's unfair to exclude a politician who fails a certain litmus test from the presidency.
C．Current litmus tests like abortion or gun control are not reliable indicators of public opinions.
D．Some specific litmus tests on certain issues axe fundamental in shaping people' s judgment of politicians.

Questions 31 to 35 are based on the following passage. Clothes play a critical part in the conclusions we reach by providing clues to who people are, who they are not, and who they would like to be. They tell us a good deal about the wearer’s background, personality, status, mood, and social outlook.
Since clothes are such an important source of social information, we can use them to manipulate people’s impression of us. Our appearance assumes particular significance in the initial phases of interaction that is likely to occur. An elderly middle class man or woman may be alienated (疏远…) by a young adult who is dressed in an unconventional manner, regardless of the person’s education, background, or interests.
People tend to agree on what certain types of clothes mean. Adolescent girls can easily agree on the lifestyles of girls who wear certain outfits (套装), including the number of boyfriends they likely have had and whether they smoke or drink. Newscasters, or the announcers who read the news on TV, are considered to be more convincing, honest, and competent when they are dressed conservatively. And collage students who view themselves as taking an active role in their inter-personal relationships say they are concerned about the costumes they must wear to play these roles successfully. Moreover, many of us can relate instances in which the clothing we wore changed the way we felt about ourselves and how we act ed. Perhaps you have used clothing to gain confidence when you anticipated a stressful situation, such as a job interview, or a court appearance.
In the workplace, men have long had well defined precedents and role models for achieving success. It has been otherwise for women. A good many women in the business world are uncertain about the appropriate mixture of “masculine” and “feminine” attributes they should convey by their professional clothing. The variety of clothing alternatives to women has also been greater than that avail able for men. Male administrators tend to judge women more favorably for managerial positions when the women display less “feminine” grooming (打扮)-shorter hair, moderate use of make up, and plain tailored clothing. As one male administrator confessed, “An attractive woman is definitely going to get a longer interview, but she won’t get a job.”
第31题：According to the passage, the way we dress ________.
A) provides clues for people who are critical of us
B) indicates our likes and dislikes in choosing a career
C) has a direct influence on the way people regard us
D) is of particular importance when we get on in age
