Around the world coral reefs(珊瑚礁) are facing threats(威胁) brought by climate change and great changes in sea temperatures. While ocean warming has been the primary focus for scientists and ocean policy managers, cold events can also whiten corals. A new study by scientists compared damaged to corals exposed to heat as well as cold stress. The results show that cool temperatures can cause more damage in the short term, but heat is more destructive(破坏性的) in the long run.
Climate change is widely known to produce warming conditions in the oceans, but extreme cold-water events have become more frequent and serious as well. In 2010, for example, coral reefs around the world faced on of the coldest winters and one of the hottest summers on record.
During a unique experiment, corals under cold temperatures suffered greater damage in just days compared with heat treated corals. Yet the researchers found that corals were eventually able to adjust to the cold conditions, make their health stable and continue to grow. However, over the long term corals subjected to heat suffered more greatly than those in cold, with evidence of severe whitening and growth stoppage, which leads to death.
The coral’s ability to adjust to cool temperatures surprised the researchers, who say the study’s results show the complexities(复杂性) of monitoring coral health in response to different environmental factors(因素).
“Global warming is associated with increases but also decreases of temperatures,” said Deheyn, one of the researchers. “Not much has been known about the comparative effects of temperature decrease on corals. These results are important because they show that corals react differently to temperature differences, which is important for future management of coral reefs in the field of climate change.”

A. Corals are unable to adjust to temperature changes.

A. scientists used to pay no attention to the effect of cold events on corals
B. 2010 witnessed one of the greatest temperature differences on record
C. corals prefer warmer conditions to cold temperatures in the long run
D. global warming has nothing to do with the decrease of temperature
3.According to the research, ?????????? .
A. corals may continue to grow in cold events after a few days
B. cold events help corals grow more quickly in a short time
C. corals show no response to hot temperatures in the first days
D. corals are whitened mainly because of warm temperatures

An interview with Wynton Marsalis, a noted jazz musician

There were the older jazz musicians who hung around our house when I was young. I saw how much they practiced, how serious they were about their art. I knew then I had to work just as hard if I wanted to succeed. Of course, my father inspired me a lot, and many teachers took the time to nurture my latent and the talents of other students in our school.

Yes. We’ve done such a poor job with music education because, as a society, we haven’t maintained the kind of education that a true artist and musician needs. Young people haven’t been able to equate romance and talent with music. For instance, most of the people who make it in the music industry today have to look good. How they sound is secondary. Sarah Vaughan, Bessie Smith, Ella Fitzgerald ― those big, romantic queens of jazz music wouldn’t make it in today’s music industry, and that’s a shame. We need to teach young people about the alternatives.

Around the would people make music that, if you listen carefully to it, sounds a little like the cadence of their language. I’d call it folk music. When I’m away from home, I make a point of listening to regional folk music, not what’s on the radio.

The same music is on the radio all over the world, and the American sound is overwhelming. Even the pop music that’s produced and created in foreign countries has that American beat, that underscore of funk. As a musician, I’m not interested in hearing recycled versions of the same genre over and over. Any music that doesn’t have a development section just isn’t interesting to me.

The music press has so much to introduce these days, and jazz is just a small fraction of it. Because some people are intimidated by jazz, they don’t cover it unless it’s a big name. New jazz musicians don’t get much of break. A lot of editors don’t say anything about jazz these days unless it’s Marsalis. That’s a shame. What VH1 is doing with their Save the Music campaign is phenomenal. They’re getting all these instruments out to needy kids. It’s the kind of thing all networks should be doing.
Kieron Williamson, a seven-year-old British boy, is being recognized as an art genius after selling 16 paintings for 18, 000 pounds in just 14 minutes. This boy has artistic skills that would be the envy of any serious painter and drawn comparisons to Pablo Picasso, a child prodigy（神童）who became one of the most recognized artists of the 20th century.
now, with so much still to learn, there’s only one thing he wants to be when he grows up. He said, “I think I’ll definitely be an artist. ”
