听力原文： President Bush has apologized for U. S. soldiers who abused prisoners in Iraq. The apology came during a meeting with Jordan's King Abdullah.
President Bush says he told King Abdullah that those responsible for the wrongdoing will be brought to justice, and their actions do not represent American values.
"I told him I was sorry for the humiliation suffered by the Iraqi prisoners and the humiliation suffered by their families. I told him I was equally sorry that people who have been seeing those pictures didn't understand the true nature and heart of America, "Mr. Bush said.
Mr. Bush says he and Americans are sickened by images of the abuse, which he says are a stain on America's reputation.
In interviews Wednesday with Arab-language television stations, Mr. Bush denounced the abuse, but stepped short of apologizing for it.
King Abdullah said Jordanians were also horrified by the images, but he is confident the abuse does not reflect U. S. morals or standards.
During his talk with King Abdullah, President Bush______.
A．denied that U. S. soldiers were to blame for their abuse of prisoners in Iraq
B．refused to admit that it was an error to launch the war on Iraq
C．made an apology for American soldiers' abuse of prisoners in Iraq
D．required Jordan to give help in fighting against terrorism

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.

Never use any drug unless there is a good reason, especially for the woman who is expecting a baby. Ask the patient if he has had previous drug reactions: if he has, be careful. It is estimated that more than half of the adverse reactions that are reported would be prevented if this were done. Ask the patient ff he is already receiving other drugs.
If possible, use a drug with which you are familiar. If you use a new drug, be especially on the watch for adverse reactions. Report serious or unusual reactions suspected as due to established drugs, and any reaction however slight that may be due to a newly marketed drug.
This is a set of recommendations for ______.
A．doctors prescribing for patients
B．doctors training people who take drugs
C．drug companies
D．persons who sell drugs

For American's high school seniors, April is the cruelest month. That's when colleges flood postal system with news of who has won a place in next fall's freshman class. For more than a few families, a difficult decision will follow: is it worth paying some $125,000 to give their child an education at an elite private college？ Or would her future be just as bright if she went to a less expensive school？
These questions have no easy answers. It is tree that big law firms as well as those leading American establishments—Sullivan & Cromwell—a gilt-edged diploma is a distinct advantage. However, there is plenty of evidence to prove that an elite education is not that necessary. According to a survey by Fortune, the majority of top CEOs did not attend an elite college(though a small number did.)
So what kind of return is there likely to be on that $125,000 investment？ On average, a person with an undergraduate degree now earns almost twice as much as someone with only a high school diploma. Some researchers found that those who attend more prestigious schools reported higher earnings.
Then Alan Krueger, an economist at Princeton and Dale, a researcher designed a study. They found no economic advantage in attending a selective college. Their study looked at freshman class at 30 schools, ranging from Yale to Denison. Krueger and Dale's research while intriguing is not definitive. Even they themselves find it odd that the results seem to show that while there is a correlation between college selectivity and future income, the more a college costs, the higher the earning of its graduates.
Critics have questioned their research—the limited number and range of schools evaluated, and conclusions. Under such circumstances, it is hard to say which is right and which is wrong. What can be said is that 1) An elite education gives students—especially less rich ones—better access to certain kinds of elite jobs. 2) There is no economic advantage to choosing an expensive, but not very good private schools. 3) Talented students everywhere rise to the top. So the future is in the hands of young men themselves.
Why is April the cruelest month for American high school seniors？
A．Because April is the month when they have the college entrance examination.
B．Because April is the time when the high school will decide whether they can graduate or not.
C．Because April is the time for high school seniors to find jobs.
D．Because April is the month for colleges to inform. the students who will have the chance to have further education.

Suicide has been a cause of concern in most societies for a long time. The classical Greeks, for example, required people who wanted to kill themselves to get permission from the senate. While this law is not without humor by today&39; s standards, it clearly shows an awareness of the problem in times gone by.
In today&39; s society, suicide is much more prevalent than we want to admit. Why do people try to take their own lives？
The motives for suicide can be categorized into areas such as a failure, wrath（暴怒）, the needfor attention, stress, and so on. However, the qualities of a person who wants to take his own life change from person to person, making it difficult to depict（描写）the typical victim. To make the problem even more confusing, people will often camouflage（掩盖）their true feelings, thus causing their friends to disregard problems that should be viewed as serious.
In the United States, a network of centers has been created to attempt to prevent suicides.People who are bitter, worded, or depressed are encouraged to contact workers at these centers. These workers, often trained volunteers, offer benevolent advice to the callers, trying to help the callers to see that suicide as a solutions to problems is an illusion. The accomplishments of these centers, insofar（到这个程度）as their effectiveness to reduce suicide is concerned, are minimal However, they have helped a lot of people with a wide variety of problems.So, in the somewhat amorphous（难以名状的）area of man helping his fellow man, they are certainly a success.
Which of the following statements is TRUE according to the article？
A.The classical Greeks did not know the existence of suicide
B.Suicide has always been prevalent in all parts of the world
C.In today’s society, there are quite a number of people who commit suicide
D.Nowadays suicide is not as common as it was in the past
Which of the following is NOT mentioned as a motive for suicide？A.Insanity
B.Pressure
C.The need for attention
D.Great anger
Which of the following statements is NOT true？A.People who want to take their own lives often disguise their feelings
B.It is difficult to describe what kind of people tend to commit suicide
C.Suicide has been a problem in most societies since ancient times
D.People who commit suicide all share certain characteristics
The word “benevolent” means （）A.relevant
B.kind
C.serious
D.effective
The third paragraph mainly tells us that （）A.a network of centers has been quite effective in reducing suicide
B.a network of centers has been quite successful in reducing suicide
C.people are making efforts to help those who tend to commit suicide and in a way, they are successful
D.in theUnited States, people who want to commit suicide call a network of centers to get help
