　　Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday．

　　They found that when people listened to their favorite music, their blood vessels(血管)dilated in much the same way as when they are laughing, or taking blood medications．

　　“We have a pretty impressive effect,”said Dr Michael Miller, director of preventive cardiology(心脏病学)at the University of Maryland Medical Center in Baltimore．

　　“Blood vessel diameter improved,”he said．“The vessel opened up pretty significantly．You can see the vessels opening up with other activities such as exercise．”A similar effect is seen with drugs such as statins．

　　When blood vessels open up more, blood flows more smoothly and is less likely to form the clots(凝块)that cause heart attacks and strokes．“We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health,”said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans．

　　Miller’s team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music．They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function．

　　Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music．Listening to music they disliked－in most cases in this group heavy metal－blood vessels narrowed by six percent, Miller said．

　　Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly．“I asked myself what other things make us feel real good, besides calories from dark chocolate of course．Music came to mind…It makes me feel really good,”he said．

　　Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual．

(1)

[　　]
A．	widen

A．	blood clots are caused by heart attacks and strokes
B．	music is better than chocolate for your health
C．	the style of music has different effects on different people

D．	A local newspaper．

(5)

　　Some people do not like anything to be out of place, they are never late for work; they return their books to the library on time; they remember people's birthday and they pay their bills as soon as they arrive. Mr Dodds is such a person.

A Giant Leap for China

　　A few days ago, he was just Colonel(上校)Yang; few people knew his name or recognized his face．But last Thursday, when he came back to the earth after a 21-hour trip to space, Yang Liwei’s smile was seen across the world above the magic words：“China’s first spaceman”．

　　The 38-year-old astronaut was sent into space at 9 a. m．Last Wednesday by China’s Shenzhou Ⅴ spacecraft, which orbited the earth 14 times．He landed safely at 6∶23 a. m．The next day, making China the third country successfully send a person into space, after the former Soviet Union and the US．

　　Yang was satisfied with his job．“I have seen many landing scenes before on video, and I think ours was one of the most successful, ”He said on a special plane to Beijing after landing．Born into an ordinary family in Liaoning Province, he became a pilot in the Chinese Air Force in 1987, spending 1350 hours in the air．He joined the Chinese space programme 11 years later．

　　While in space, Yang recorded everything he saw as well as showing China’s national flag and the United Nations’ flag to the people watching on TV at home．He also ate a meal of diced chicken and fried rice, before taking a 3-hour nap．The whole project went according to plan, but space exploration is not as easy as it seems．

　　Anyone who saw the destruction of the US space shuttle Columbia in February this year will know that Yang took a great risk．

　　He experienced extremely high temperatures, while the gravitation(重力)on take-off and landing were strong enough to force tears from his eyes．

　　He has spent five years training to become a spaceman．

　　“I eat all of my meals at the space programme’s dinning room and have never been able to take my son to kindergarten, ”he said．“I’ve never met his teachers．”

　　But becoming China’s first spaceman has made all the effort worthwhile．

　　“When I boarded the spacecraft for the first time, I couldn’t help feeling excited,” he said．“I decided that I had to fly it．”

　　To Chinese people, Yang is now a hero．One visitor to a Xinhua news agency online forum(网上论坛)said, “Yang’s trip is a giant leap forward for China．”

　　Officials say the next Shenzhou will be launched by 2005．China also plans to develop spacewalking and a space lab．

(1)

What is the main idea of the story?
[　　]
A．	China’s first manned flight．
B．	A hero with great courage．
C．	The first Chinese man in space．
D．	How Yang Liwei became China’s first spaceman．

(2)

B．	1.5 hours．
C．	6 hours．
D．	The story didn’t mention it．

(3)

Why did the writer mention the gravitation forces on take-off and landing?
[　　]
A．	Because it was the most dangerous part of the space flight．
B．	Because it was a very special experience．
C．	To stress how much training he had to do to prepare for the flight．
D．	To show that Yang is brave．

(4)

Why did the writer use “giant leap” in the title?
[　　]
A．	Because the space flight marked China’s great progress in the field of space exploration．
B．	Because Neil Armstrong said it was a “giant leap” for mankind when he first set foot on the moon．
C．	Because the space flight was a huge success．
D．	Both A and B．

　　A few days ago I asked my son's governess(女家庭教师)Julia to come into my study．“Be seated, Julia,”I said, “Let's settle our accounts．I guess you most likely need some money, but maybe you're too polite to mention it．Now then, we agreed on thirty dollars a month…”

　　“Forty．”

　　“No, thirty．I made a note of it．I always pay our governess thirty．Well, um, you've been here two months, so…”

　　“Two months and five days．”

　　“Exactly two months．I made a special note of it．That means you have sixty dollars coming to you．Take off nine Sundays…you know you didn't work with Tom on Sundays, you only took walks．And three holidays…”Julia was biting her finger nail nervously, her face red, but－not a word．

　　“Three holidays, therefore take off twelve dollars．Four days Tom was sick and there were no lessons, as you were occupied(从事)only with Dick．Three days you had a toothache and my wife gave you permission not to work after lunch．Twelve and seven-nineteen．Take nineteen off…that leaves…hmm…forty one dollars．Correct?”

　　Julia's left eye reddened with tears welling up．Her chin trembled; she coughed nervously and blew her nose, but－still not a word．

　　“Around New Year's Day you broke a teacup and a saucer; take off two dollars．The cup cost more, it was a treasure of the family, but － forget it．When didn't I take a loss! Then, due to your neglect(疏忽), Tom climbed a tree and tore his jacket; take away ten．Also due to your carelessness the maid stole Dick's shoes．You ought to watch everything! You get paid for it．So, that means five more dollars off．The tenth of January I gave ten dollars．”

　　“You didn't．” sobbed Julia．

　　“But I made a note of it．”

　　“Well…if you say so．”

　　“Take twenty seven from forty one－that leaves fourteen．”

　　Both her eyes were filled with tears．Beads of sweat stood on the thin pretty little nose．Poor girl!

　　“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife．Three dollars, nothing more．”

　　“Really? You see now, and I didn't know that! Take three from fourteen－that leaves eleven．Here's your money, my dear．Three, three, three, one and one．Here it is!”

　　I handed her eleven dollars．She took them and pocketed them．

　　“Merci(法语：谢谢),”she whispered．

　　I jumped to my feet and started pacing the room．I was overcome with anger．“For what, this ‘merci'?” I asked．

　　“For the money．”

　　“But you know I've cheated you－robbed you! I have actually stolen from you! Why this ‘merci'?”

　　“In my other places they didn't give me anything at all．”

　　“They didn't give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you．．．I m going to give you all the eighty dollars! Here they are in the envelope all ready for you．．．Is it really possible to be so spineless(懦弱)?Why didn't you protest? Why were you silent? Is it possible in this world to be without teeth and claws(爪)－to be such a fool?”

　　Embarrassed, she smiled．And I could read her expression, “It is possible．”

　　I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars．She murmured her little “merci” several times and went out．I looked after her and thought, “How easy it is to crush(压榨)the weak in this world !”

(1)

A．	nervousness in front of her boss
B．	acceptance of injustice(不公平)
C．	shyness when talking about money
