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 really 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.

Brian knew he had been drinking more and more, but he was convinced that he'd return to more moderate drinking when he wasn't so pressured at work, and that "a few too many drinks now and then" wasn't a major problem.
"My wife and father were on me to stop drinking, but you know how critical and protective family can be," said Brian. "So I blew them off."
It wasn't until his friend Jack spoke up that Brian started to think differently. "That really hit home, because I wouldn’t expect a friend to confront me with something that personal unless it was very important," said Brian. "Jack said he was really concerned about me. He pointed out that my personality changed after I had a few beers--that I became belligerent(寻衅的). For a normally easy-going guy, that was a dramatic change in behavior."
Jack could see that Brian's numerous drinking binges(放纵) were causing problems. Brian was frequently calling into work sick and falling behind in his work, and his marriage was seriously on the ropes. Brian was teetering(摇摇欲坠) on the edge of disaster. "I didn't want to see a good life and a good friendship ruined," said Jack, "so I approached Brian, shared my honest observations with him, and suggested that he seek help."
After a couple days of soul searching, though still reluctant, Brian took Jack's suggestion and was assessed by an addictionprofessional. The expert recommended that Brian check into a treatment center, and one day later Brian did so.
Many people fear taking the path that Jack took. Speaking up to a friend who may have a problem with alcohol or other drugs can be a tricky undertaking.
Yet it's true that a concerned friend can do a lot. Most people don't recognize they have a substance abuse problem and most don't seek help for a problem until someone close to them intervenes(干预).

A. He suffered from an illness called alcohol addiction.

C. He became morally corrupted drinking too much all day.
D. He drank a little more than normal to escape the pressure.
2.What does “that” in the 3rd paragraph refer to?
A. Brian’s drinking binges. B. Jack’s talk with Brian.

3. Brian could accept Jack’s suggestions mainly because ____________.
A. he found his friend was very critical and protective
B. Jack’s suggestions were professional and persuasive
C. Jack and Brian’s family had different opinions
D. he knew his friend wouldn’t easily intervene his personal affair
4. Brian’s alcohol abuse brought him many problems EXCEPT ____________.
A. his refusal to listen to his family B. his bad temper and aggressiveness

阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
What is a creepy crawly?
A few years ago, I was on a bicycle trip when I got off my bike for a rest. I sat down on the grass. A few seconds later, I was covered in ants. They were swarming all over me so I got up and brushed them off. It was a strange experience but I soon forgot about it.
A couple of years later, I was living in Jordan. I had just moved into a modern flat and was unpacking plates when I saw something move out of the corner of my eye. I looked over at the kitchen drawer and there was a cockroach crawling out of it. I screamed. Then I grabbed a can of insecticide and sprayed it on the cockroach. He ran under the nearby bathroom door. It took me three days before I found the courage to open the bathroom door to see if he was still alive. He wasn’t.
Why did I react so violently to one lone insect when a closer encounter with hundreds of ants hardly affected me? The answer is easy: because cockroaches are creepy crawlies and ants aren’t. Creepy crawlies are those little bugs which provoke feelings such as uneasiness, anxiety or dislike – they make your skin crawl.
Did you know that some people feel such a fear of bugs that it becomes a phobia? Psychologists have offered many explanations. Some say we associate them with dirt and disease. Or that these are life forms that are so alien to us, that we find them repulsive(令人厌恶的) for their dissimilarity.
Insects, however, don’t follow our rules – they just do what they want and invade our space. Unfortunately, although insects and bugs have been a successful animal species up to now, many of them, like many other species nowadays, are under threat of extinction. Entomologists warn that this could upset entire ecosystems and lead to all kinds of disastrous consequences.
So my plea to you is: the next time you feel the urge to stamp on, splatter or spray a creepy crawly, give a thought to the planet and stop.

D. Because meeting the ants is an unusual experience that the author can hardly forget.

C. liquid for killing insects. D. cleanser for the bathroom.
3. How does the author feel about the bugs like cockroaches?
A. The author doesn’t mind the contact with those harmless small creatures.
B. They make the author feel so awful that they should be killed.
C. They invade our space and become a threat to humans.

When I was a ten-year-old girl, I was once asked to deliver a speech titled “A Real Test in My Life”. To talk before the whole class! Just imagine how 31 (terrible) shy I was the moment I thought of that 32 so many eyes fixed upon me. I had no other choice, though.

But the hard part 33 (lie) in my oral presentation; to read from 34 paper was not allowed; I had to give the speech 35 my memory and in front of such a big audience! A real trial began when I stood on the platform with my legs trembling and my mind blank. How much time had passed by, I didn’t know. My listeners were still waiting, patiently and without any signs of rushing me. Gradually I found 36 back, giving out my speech with difficulty. Finally I finished. After 37 seemed to be a hundred years, I found my audience applauding. I made it! From then on, my fear of talking before an audience 38 (appear).

Overcome it, 40 we will be able to achieve our goals.

AVERAGE RESOURCES
620 m³water	If we put fresh water and sea water together, we can each have 620 m³ water. But remember, sea water is too salty for us to drink if the factories don’t process it first. So, 620 m³ is little. Saving water in daily use is important.
0.5 hectares of forests	There are 3.869 billion hectares(公顷) of forests on Earth. But we are losing them mainly because we cut trees too much. If we calculate（计算）at the size of a football field, we are losing 343,000 football fields every day, or 1,431 per hour, or 24 per minute!
1.5 centimeters long corals(珊瑚)	All the corals that we have now spread for about 100,000 km in 109 countries. But each of us can only have such a little piece, because seas are getting polluted and corals are dying.
33 stars	According to the latest report, there are 200 billion stars in the Milky Way. Each of us can have 33 of them. Unfortunately, we cannot see most of the 200 billion stars from Earth. We can only see about 6,000 stars. If we don’t use telescopes or we have bad weathers, we can only see about 2,000 stars.
90kg rice	On average, we harvest 0.54 billion tons of rice each year round the world and each of us can have 90 kg. Asia produces and eats 90% of all the rice. How long will it take you to eat up this 90 kg rice?
1 iceberg	Luckily, we still have icebergs to share when Earth gets warmer and warmer. Each of us can have an iceberg of 170m×170m×170m. Up to 10% of Earth surface is covered by ice. There is 31,000,000km³ of ice on Earth in all.

A．the man-made damage	B．the climate change
C．the construction of many football fields	D．the environmental pollution
