They say that before long，we will be able to receive more than 500 television networks on cable or by satellite .Some people think that it"s ridiculous to have that many channels．Their usual criticism goes something like this：
“I already get more channels on my TV than I have time to watch．No one needs to see that much TV．There’s not enough time in the day to watch all that!”They also state that most of what’s on television now isn’t worth watching in the first place．
I think they’re missing the point．If the local library wanted to add another 5,000books,would
we say“That’s silly,we’ll never have time to read all those books．”?The point is that we would
have more choices．
I don’t believe that most people should watch more television And if we had 500 or even 1,000 channels to choose from，we wouldn’t have to spend more time watching the tube．We would．however,have a better selection of programs to choose from．That means that the quality of our viewing time would improve．
I，for one，say that the more channels we can access，the better,Give me more choices! If they’re not worth my time，I’ll just hit the“off”button．

One survey revealed that 60 percent ofowner-builders also design their homes．Many others
buy commercial house plans for less than $100 or use plans available from the U．S． Department ofAgriculture．

Birds in cities are damaging their health by trying to sing above the noise of urban life．
New research shows that male birds are trying to compete against traffic and city sounds．They are now singing louder and at higher frequencies，which could harm their vocal cords．Some birds are choosing to sing at night instead of dudng the day．This makes them more open to attack and also creates stress and exhanstion．
“The difference between urban and rural birdsong is becoming so big that the two groups could now be unable to communicate．This could lead to inbreeding and a weak gene pool．”said Dr Sue Anne Zollinger of the University of St Andrews．
According to Zollingar,a bird group with a small geae pool might adapt less quickly to new diseases and could be wiped out．
A study of the dawn chorus found that birds in Berlin sang up to 14 decibels(分贝)louder than those in the forest．The birds sang loudest on weekday momings．
“By trying to sing over the sound of the city,birds are rising vocal injury,”said Zollinger．“All this puts the sarne strain on a bird’s vocal cords as when ahuman need to shout to be heard—except the birds are doing it all day,every day,”she said．
“Singing under such pressure means birds have less control over the sound they produce． Their songs may lose quality and become more rough—sounding．”said Zollinger．This could make them appear less attractive to female birds．
Mark Constantine，author of The Sound Approach to Birding，said：“Birdsong is important for our quality of life and has been proved to reduce our blood pressure．When we live in the centre of large，urban areas，we get stressed and it"s extremely good to have birdsong around us．The impact on humans of birdsong is massive．It harms us，as well as the birds，if their songs become louder and simpler
53．Some birds in cities now choose to sing at night time because_______．
A．they want to attract more birds of opposite sex
B．they are more likely to be discovered by their family
C．they can’t adapt to the loud noises during the daytime
D．they have to frighten their enemy away
54．According to the passage，urban and rural birds might not be able to_______．
A．recognize each other
B communicate with each other
C live with each other
D．compete against each other
55．It requires greatest efforts for birds in cities to sing o_______．
A．Monday nights B．Wednesday afternoons
C．Saturday Evenings D．Friday momings
56．According to Dr Sue Anne Zollinger,birds singing louder might eventually lead to_______．
A．the harm done to man’s health
B the dying out of a species
C．the serious damage to the bird’s vocal cords
D．the decrease ofthe birth rate ofa bird group

Researchers Look Behind the Tears to Study Crying
Many people found themselves unusually moved by the historic presidential inauguration(就职演说)last week in Washington Watching the huge crowds，we saw laughter，cheers，hugs-but also many tears
It made us wonder,why dopeople cry?Surely tears must be good for us—away to calm the mind and cleanse the body．Yet studies show that crying sometimes makes people feel worse．
Three researchers in Florida and the Netherlands recently looked more deeply into the subject． They examined detailed descriptions ofcrying experiences．Psychologist Jonathan Rottenberg at the University of South Florida says they wanted to study crying as it happens in everyday life，not in a laboratory．
The team analyzed information from the Intemational Study on Adult Crying．As part of that study，three thousand people in different countries，mostly college students，wrote about recent crying experiences．They noted causes，surroundings and any people involved in the event．They also reported how they felt after they cried．
Professor Roaenberg says the research showed that all crying experiences are not created equal. Crying does not always make a person feel better，he says．About ten percent of people reported feeling worse after they cried．
But a third felt better after crying．And a majority reported the experience as helpful．
The research showed that people who cry alone may not do as well as those with others around． People who reached out for emotional support at the time-and received it-reported better results from the crying experience．
But Professor Rottenberg says those who felt shame or embarrassment while crying were less likely to report that crying had been helpful．
Research has shown that women cry more of ten and more intensely than men．But it may not be to better effect，says the psychologist．The new findings，he says，did not show that a person’s sex was an advantage of beneficial crying．In other words，just because women cry more does not mean they are more likely to have a“good”cry．
The paper entitled”Is Crying Beneficial?”appeared in December in Current Directions in Psychological Scieflce And there is more to learn．Jonathan Rottenberg says the science ofcrying is still in its infancy．
57·Why did the author mention the presidential inauguration in Washington in the first paragraph?
A．Because he was impressed by the laughter,cheers，hugs and tears．
B．Because he wanted to introduce the topic about crying．
C．Because he wanted to show people’s dissatisfaction with the result．
D．Because it was the historic moment that many people cried
58．How did the researchers carry out the research?
A．They studied crying experiences not only in everyday life but also in labs．
B．They collected the crying experiences of the students at the colleges．
C They studied the crying experiences of grown-ups from various countries．
D．They noted their own crying experiencesand compared with others．
59．We can learn from the passage that_______．
A．it may be better to cry alone than with others around
B．some support from others may make crying helpful
C．women who cry more of ten may have better effects than men
D．the effects will be better if you feel shy while crying
60．The underlined phrase in the last paragraph probably means_______．
A．in the early stage B．in a secret state C．in the first place D in good condition
