The worst thing about television and radio is that they entertain us, saving us the trouble of entertaining ourselves.
A hundred years ago, before all these devices were invented, if a person wanted to entertain himself with a song or a piece of music, he would have to do the singing himself or pick up a violin and play it. Now, all he has to do is turn on the radio or TV. As a result, singing and music have declined.
Italians used to sing all the time. Now, they only do it in Hollywood movies, Indian movies are mostly a series of songs and dances trapped around silly stories. As a result, they don't do much singing in Indian villages anymore. Indeed, ever since radio first came to life, there has been a terrible decline in amateur (业余的) singing throughout the world.
There are two reasons for this sad decline. One, human beings are astonishingly lazy. Put a lift in a building, and people would rather take it than climb even two flights of steps. Similarly, invent a machine that sings, and people would rather let the machine sing than sing themselves. The other reason is that people are easily embarrassed. When there is a famous, talented musician readily available by pushing a button, which amateur violinist or pianist would want to try to entertain family or friends by himself?
These earnest reflections came to me recently when two CDs arrived in the mail. They are historic recordings of famous writers reading their own works. It was thrilling to hear the voices from a long dead past in the late 19th century. But today, reading out loud anything is no longer common. Today, we sing songs to our children until they are about two, we read simple books to them till they are about five, and once they have learnt to read themselves, we become deaf. We're alive only to the sound of the TV and the stereo (立体声音响).
I count myself extremely lucky to have been born before TV became so common: I was about six before TV appeared. To keep us entertained my mother had to do a good deal of singing and tell us endless tales. It was the same in many other homes. People spoke a language; they sang it, they recited it; it was something they could feel.
Professional actors' performance is extraordinarily revealing. But I still prefer my own reading, because it's mine. For the same reason, people find karaoke (卡拉OK) liberating. It is almost the only electronic thing that gives them back their own voice. Even if their voices are hopelessly out of tune, at least it is meaningful self-entertainment.
The main idea of this passage is that ______.
A.TV and radio can amuse us with beautiful songs and music
B.TV and radio prevent us from self-entertainment
C.people should sing songs and read books aloud themselves
D.parents should sing songs and read books aloud to their children

If there is any single factor that makes success in living, it is the ability to be benefited by defeat. Every success I know has been achieved because the person was able to analyze (分析) defeat and actually learn something from it in his next undertaking (从事的工作). Wrongly taking defeat for failure, you are sure indeed to fail, for it isn't defeat that makes you fail; it is your own refusal to see the guide and encouragement to success in defeat.
Defeats are nothing to be afraid of. They are common incidents in the life of every man who achieves success. But defeat is a dead loss unless you do face it, analyze it and learn why you failed. Defeat, in other words, can help to get rid of its own cause. Not only does defeat prepare us for success but nothing can cause within us such a strong wish to succeed. If you left a baby grasp a stick and try to pull it away, he will hold it more and moro tightly until his whole weight is hung up. It is this same reaction that should give you new and greater strength every time you are defeated. If you make full use of the power which defeat gives; you can compete with it far more than you are able to.
How much does the writer know about success?
A.He knows at least several examples of success.
B.He knows every success in life.
C.He knows every success that has been achieved by man.
D.It is not referred to.

Opponents of affirmative action say the battle over the use of race in college admissions is hardly over, despite the Supreme Court's ruling Monday upholding the goal of a diverse student body. Higher education leaders overwhelmingly hailed the decision, saying it reaffirmed policies used by most .selective colleges and universities. But some critics raised the possibility of more lawsuits, and promised to continue pressuring the Department of Education's Office of Civil Rights to investigate questionable policies. "We're talking about admission programs, scholarships, any program only for minorities or in which the standards used to judge admissions are substantially different," says Linda Chavez, founder and president of the Center for Equal Opportunity, a conservative non-profit group.
Others say they'll take their case to voters. "We have to seriously contest all this at the ballot box," says University of California regent Ward Connerly, who helped win voter approval of California's Proposition 209, which prohibits considering race or gender in public education, hiring and contracting. Because of that law, Monday's ruling had no practical impact in the state. "It may be time for us to let the (Michigan) voters decide if they want to use race as a factor in admissions," Connerly said Monday.
Meanwhile, U. S. Education Secretary Rod Paige, consistent with President Bushes stance opposing affirmative action, said the Department of Education will "continue examining and highlighting effective race-neutral approaches to ensure broad access to and diversity within our public institutions". Even Supreme Court Justice Sandra Day O'Connor, in one of the opinions, recommended that states look for lessons in race-neutral programs being tried in California and elsewhere. While the ruling said admission officials may consider race in the selection process, colleges and universities are not obligated to do so. "Ultimately in the debate, diversity is a choice, not a legal mandate", says Arthur Coleman, a former Department of Education official who now helps colleges and universities ensure constitutional policies.
The public, too, remains conflicted, largely along racial lines. According to a January poll by the non-profit research organization Public Agenda, 79% of Americans said it is important for colleges to have a racially diverse student body, while just 54% said affirmative action programs should continue. In a Gallup poll conducted days before the ruling, 49% of adults said they favor affirmative action and 43% did not, with blacks and Hispanics far more likely to favor the practice than whites. And some educators doubt that with Monday's ruling, those opposing affirmative action will change their minds.
For now, admission officials and university lawyers are poring over the ruling to determine how or whether to adjust policies. While most tend to be closed-mouthed about admission policies, many say they don't expect significant changes.
What the critics said in the first paragraph amounts to the idea that ______.
A.no admission policies based on race should be implemented
B.minority applicants should be given favorable considerations
C.different standards for admitting minority students should be set up
D.selective colleges and universities should be punished for their discrimin--atory policies

People in the US can now carry an artificial intelligence (AI) around in their pocket, whe
People in the US can now carry an artificial intelligence (AI) around in their pocket, where it waits patiently to be told what to do.
Siri, an iPhone application that understands spoken commands and uses the web to carry them out,is a byproduct from a US military project to develop an artificially intelligent assistant.
Many people's experience of a "virtual assistant" may be limited to Microsoft's annoying classic Mr. Clippy. But in the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop. It wasn't even stumped when I asked "do I need my umbrella today?" coming straight back with the local weather forecast.
A typical command might be: "Reserve a table for two at a good French restaurant in San Francisco." Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger.
In some ways Siri is just a fancy front-end to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what's new is the way it can interpret the intentions of its master or mistress and use those sites to put them into action.
Doing that requires the ability to actually understand the meaning of words you use, not just passing on keywords blindly, says Siri co-founder Adam Cheyer.
"Book a four-star restaurant in Boston seems pretty straightforward," says Cheyer, "until you realise that Book is a city in the US, and Star is also a city in the US, and there are 13 Bostons, and Star is also the name of a restaurant."
To cut through what Cheyer calls the "combined explosion of interpretations", Siri uses your location, and the history of the commands you've given. It knows that "book" is most likely a command verb, unless you happen to be near the city of Book.
Siri attaches probabilities to the interpretation of each word and cross-reference(参照) with your location and other data, some of which you must provide yourself.
According to the passage, Siri is most probably ______.
A.still at its experimental stage
B.very popular with iPhone users
C.a US military assistant software
D.an artificial intelligence software
