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.”Which of the following is TRUE according to the passage?
| A．Corals are unable to adjust to temperature changes. |
| B．Cold temperature causes greater damage to corals. |
| C．Hot temperature helps coral reefs to grow quickly. |
| D．Heat and cold damage corals in their own ways. |

| 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 |

Television has turned 88 years old on September 7, 2015, and it has never looked better. In its youth, television was a piece of furniture with a tiny, round screen showing unclear pictures of low-budget programs. In spite of its shortcomings, it became popular. Between 1950 and 1963, the number of American families with a television jumped from 9% to 92% of the population.
As the audience got larger, the technology got better. Television sets became more reliable through the 1960s. The reception (接收效果) improved. The picture improved. The major networks started broadcasting programs in color.
Even greater improvements were coming according to Sanford Brown, who wrote an article for the Post in 1967. Surprisingly, just about every prediction he made in the article became a reality. For example: All sets in the not-distant future will be color instruments. He also predicted that TV sets would become smaller, simpler, more reliable and less expensive and may forever put the TV repairman out of work. Smaller sets do not, of course, mean smaller screens. TV engineers expect screens to get much bigger. However, today’s 3-D TV is even farther away, if it’s coming at all. There is some doubt whether the public would be eager to pay for it, in view of people’s cold reception given to 3-D movies.
But the technology with the greatest potential, according to Brown, was cable television (有线电视), which was still in its early stages then. As he predicted, the future of cable television was highly interactive (互动的). It wasn’t cable television that gave Americans their electronic connection to the world, however. It was the Internet. He even foresaw the future office: using picture phones, big-screen televisions for conferences, and computers providing information at the touch of a button.
Brown ever said, “The future of television is no longer a question of what we can invent. It’s a question of what we want.” What can we infer about television sets in the 1960s?
| A．They were very popular with Americans. |
| B．The reception showed no improvement. |
| C．They showed black-and-white pictures. |
| D．They were out of order now and then. |
Which of the followings did Sanford Brown fail to predict?
| A．Television’s good quality. |
| B．The invention of 3-D TV. |
| C．The future office’s model. |
| D．The potential of cable TV. |
What is the text mainly about?
| A．The shortcomings of television. |
| B．The bright future of television. |
| C．The development of television. |
| D．The invention of television. |
My 17-year-old daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production, one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night light, she takes one last look at the bedroom and says, “Dear night lights, protect my sleeping children.” As a mother, I know how much she loves her children.
It has been several weeks since we took our daughter to college and she seems to be adjusting well after a short period of homesickness. For us, though, it’s another story. Like most parents, I love checking in on my children at night. But now she’s gone, and I find nighttimes the hardest. I miss her most at night.
In my neighborhood, most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. One friend talked about getting this sick feeling in her stomach as she prepared for the college drop-off. We complained that many of us were too busy to truly enjoy being with our children while we had them.
For us moms, seeing Toy Story 3 only made the sadness worse as we watched the character Andy, who is the same age as our kids, say goodbye to his childhood as he prepares to leave for college. And it’s not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn’t get any easier. “You feel like something has been taken away from inside you，” said one of them.
I imagine things will get easier with time, especially as I see my daughter adjust to college life. Meanwhile, as I keep my cell phone close to me in bed and text my daughter goodnight and sweet dreams every night, I like to think at messages serve as a night light that keeps her safe.The writer was deeply impressed by the scene in Peter Pan because ________.
| A．she watched the scene with her daughter |
| B．the scene was very exciting and interesting |

Having a great collection of books at home doesn’t really mean that you are a person who has a passion for literature and reading. It can be a family inheritance（继承） or it can be just to impress people around you about the fact that you are a person of culture. On the other hand, there are many persons who cannot afford to buy books, because some of them are quite expensive, but they usually go to libraries and spend hours reading something that interests them a lot, or just borrow books to read at home.
From my point of view, literature is very important in our lives from several points of view. For example, reading is a means of gaining culture and enriching our knowledge in different areas of activities. It can help us have a great imagination and it makes things easier when it comes to making compositions on different themes. It gives you the possibility to speak about science, even if you don’t work in this field, or you can express your opinion about a political aspect, just because you have read something connected to that.
Secondly, literature offers us the possibility to enter the world of imagination, and to leave apart the real one for a couple of hours. We come to meet kings and queens many years ago, dream in the world of the rich or imagine how life will be in the future. Sometimes, we identify ourselves with the characters in the stories we read and they can give us some clues to solve our problems and how to react in certain circumstances.
To conclude, I would like to say that literature is the perfect means to enrich our culture, to express correctly and have a rich vocabulary, to be able to interfere（干涉） in conversations in different fields of interest and to really be considered an erudite person.The people who are fond of literature are those that _________.
| A．go to libraries on weekends |
| B．buy expensive books in the bookstore |
| C．keep many books in their studies |
| D．have much interest in reading |
We can learn from the third paragraph that _________.
| A．we can bring kings and queens back to life |
| B．what we read can be useful in our daily life |
| C．it is very good for us to stay alone for some hours |
| D．we can make friends with the people in the stories |
The underlined word “erudite” in the last paragraph probably means_________.
| A．hard-working | B．enthusiastic |
| C．learned | D．creative |
What is the author’s purpose in writing the passage？
| A．To advise readers to like reading. |
| B．To explain the true meaning of reading. |
| C．To tell readers how to read a book. |
| D．To tell readers who has the real passion for literature. |
A classical guitarist was excited to hear from New York City police that his valuable guitar had been found. It disappeared almost a year ago when he got out of a cab and forgot to take the guitar with him. Laurence Lennon, 44, said he was running late that day. He was talking to his manager on his cell phone when he dashed out of the taxi. He said that he gave the driver $ 60 and told him to keep the change. He walked through the front doors of the concert hall still talking on the phone to his manager.
Upon discovering his loss, Lennon used his cell phone to call the police. The policewoman asked him for the name of the cab company, the number of the cab, and the name of the driver. He said that she had to be kidding.
She told Lennon that he could file a missing items report at the police station or online. Lennon asked for the online address. She told him that finding the guitar might take a couple of years—finding guitars was not as important as finding murderers and marijuana smokers. Then she told him to have a nice day.
“This year has been depressing，” said Lennon. “I had to put off the recording of two new CDs. I've been using borrowed guitars. And I was losing hope of ever recovering my guitar.”
Lennon was reunited with his $ 100,000 musical instrument yesterday.
