Every animal sleeps,but the reason for this has remained foggy.When lab rats are not allowed to sleep,they die within amonth. ①
One idea is that sleep helps us strengthen new memories. ② We know that,while awake,fresh memories are recorded by reinforeing (加强) connections between brain cells,but the memory processes that take place while we sleep have been unclear.
Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight,making room for fresh memories to from the next day. ③
Now we have the most direct evidence yet that he is right. ④ The synapses in the mice taken at the end of a period of sleep were 18 percent smaller than those taken before sleep,showing that the connections between neurons weaken while sleeping.
If Tononi's theory is right,it would explain why,when we miss a night's,we find it harder the nextday to concentrate and learn new information-our brains may have smaller room for new experences.
Their research also suggests how we may build lasting memories over time even though the synapscs become thinner.The team discovered that some synapses seem to be protected and stayed the same size. ⑤ "You keep what matters,”Tononi says.
A. We should also try to sleep well the night before.
B. It’s as if the brain is preserving its most important memories.
C. Similarly, when people go for a few days without sleeping, they get sick.
D. The processes take place to stop our brains becoming loaded with memories.
E. That’s why students do better in tests if they get a chance to sleep after learning.
F. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.
G. Tononi’s team measured the size of these connections, or synapses, in the brains of 12 mice.
2、How to Do Man-on-the-Street Interviews
The man-on-the-street interview is an interview in which a reporter hits the streets with a cameraman to interview people on the sport. ① But with these tips, your first man-on-the-street interview experience can be easy.
● When your boss or professor sends you out to do man-on-the-street interviews for a story, thint the topic and develop a list of about ten general questions relating to it. For example, if your topic is about environmental problems in America, you might ask, “Why do you think environmental protection is important in America?” ②
● Hit the streets with confidence.③ Say, “Excuse me, I work for XYZ News, and I was wondering if you could share your opinion about this topic.” This is a quick way to get people to warm up to you.Move on to the next person if someone tells you she is not interesteDon’t get discouraged.
● ④ Each interview that you get on the street shouldn’t be longer than ten minutes. As soon as you get the answer you need, move on to the next person. Mare that as you go from interview to interview, you are getting a variety of answers. If everyone is giving you the same answer, you won’t be able to use it. A safe number of interviews to conduct is about six to ten.⑤
● If your news station or school requires interviewees to sign release forms to appear on the air, don’t leave wort them.
A.Limit your time.
B.As you approach people, be polite.
C.If you don’t own a camera, you can buy one.
D.For new reporters, this can seem like a challenging task.
E.To get good and useful results, ask them the same question.

1、 Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.
Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.
It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jae the music more accessible, and preserve its history and culture.
“Jazz seems like it’s not really a part of the American appetite,” Moran tells National Public Radio’s reporter Neal Conan. “What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore. It’s actually color, and it’s actually digital.”
Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,” says Moran.
Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party, “Just to kind of put it back in the mind that Waller is dance music as much as it is concert music,” says Moran. “For me, it’s the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how talt ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”

Knowing how 3 Judith’s schedule was, I found her driving Meg’s children to lessons unbelievably 4 . I was about to say more about this when Donna, another colleague, entered the room 5 .

After the fifth try, she finally 14 it. She hugged me with 15 , saying thanks to me. I smiled and said it was nothing.
Suddenly, I realized that helping someone was really something to me . I learned that giving from the heart doesn’t 16 mean sacrifice and hard work. The 17 is finding something we love to do and finding someone who 18 that something. Our generosity can benefit others 19 ourselves. Once you have a good 20 of it, it’s nothing.
