Sibson rushed down the stairs barefoot to 23 ; he opened the door to the basement（地下室）, and flames 24 out. Sibson ran back upstairs to call 911 from his bedroom. “I felt 25 because the room had a separate outdoor stairway,” he explains.
Bt the phone didn’t work, and when he tried to go down the outdoor stairway, he was 26 by a wall of flames. Sibson realized he was trapped（困住）.
Sibson’s house was three kilometers 27 the main road and was so well hidden by trees that he knew calling for help would be 28 .
Up a hill nearby lived Sibson’s neighbor, Huggons. He was lying in bed when something like a smoke alarm 29 his ears. He jumped out of bed, took his 30 and flashlight, and headed down the hillside toward the 31 . That was when he saw the rolling heavy smoke.
Huggons dialed 911, and the operator warned him not to 32 the house. Bt Huggons said, “There is no way I am going to listen to Sibson 33 and die in that fire.”
“Anyone there?” Huggons called out. Then he heard “Help! I’m trapped!” coming from the second floor balcony（阳台）. He entered the house, but soon had to run back to catch his 34 .
After one more 35 inside the house, Huggons gave up and 36 around back.
The wind parted the smoke just 37 for him to catch sight of Sibson. Bt there was no way to get to him. He 38 the flashlight into the woods and noticed a ladder. He took it over to the balcony and 39 Sibson down just as the second floor of the house fell off.
Sibson is still 40 when he tells the story. “ I was alone that night,” he says. “Then I heard the most beautiful sound in my life. It was Huggons.” 【題組】21. (A)before (B) while (C) since (D)until
41.On a hill 600 feet above the surrounding land, we watch the lines of rain move across the scene, the moon rise over the hills, and the stars appear in the sky. The views invite a long look from a comfortable chair in front of the wooden house.
Every window in our wooden house has a view, and the forest and lakes seldom look the same as the hour before. Each look reminds us where we are.
There is space for our three boys to play outside, to shoot arrows, collect tree seeds, build earth houses and climb trees.
Our kids have learned the names of the trees, and with the names have come familiarity and appreciation. Athey tell all who show even a passing interest, maple（枫树）makes the best fighting sticks and white pines are the best climbing trees.
The air is clean and fresh. The water from the well has a pleasant taste, and it is perhaps the healthiest water our kids will ever drink. Though they have one glass a day of juice and the rest is water, they never say anything against that.
The seasons change just outside the door. We watch the maples turn every shade of yellow and red in the fall and note the poplars’（杨树）putting out the first green leaves of spring.

I left university with a good degree in English Literature, but no sense of what I wanted to do. Over the next six years, I was treading water, just trying to earn an income. I tried journalism, but I didn’t think I was any good, then finance, which I hated. Finally, I got a job as a rights assistant at a famous publisher. I loved working with books, although the job that I did was dull.
I had enough savings to take a year off work, and I decided to try to satisfy a deep-down wish to write a novel. Attending a Novel Writing MA course gave me the structure I needed to write my first 55,000 words.
It takes confidence to make a new start — there’s a dark period in-between where you’re neither one thing nor the other. You’re out for dinner and people ask what you do, and you’re too ashamed to say, “Well, I’m writing a novel, but I’m not quite sure if I’m going to get there.” My confidence dived. Blieving my novel could not be published, I put it aside.
Then I met an agent（代理商）who said I should send my novel out to agents. So, I did and, to my surprise, got some wonderful feedback. I felt a little hope that I might actually become a published writer and, after signing with an agent, I finished the second half of the novel.
The next problem was finding a publisher. After two-and-a-half years of no income, just waiting and wondering, a publisher offered me a book deal — that publisher turned out to be the one I once worked for.
It feels like an unbelievable stroke of luck — of fate, really. When you set out to do something different, there’s no end in sight, so to find myself in a position where I now have my own name on a contract（合同）of the publisher — to be a published writer — is unbelievably rewarding（有回报的）. 【題組】49.What does the underlined part in Paragraph 1 mean?
(A)I was waiting for good fortune.
(B) I was trying to find an admirable job.
(C) I was being aimless about a suitable job.
(D)I was doing several jobs for more pay at a time.
52.【題組】52. What does the author mainly want to tell readers in the last paragraph?
(A)It pays to stick to one’s goal.
(B) Hard work can lead to success.
(C) She feels like being unexpectedly lucky.
(D)There is no end in sight when starting to do something.
In a recent announcement, Harvard and the Massachusetts Institute of Technology（MIT）said that they have joined forces to offer free online courses in an effort to attract millions of online learners worldwide.
Bginning this fall, a number of courses developed by teachers at both universities will be offered online through a new $60 million program, known as edX. “Anyone with an Internet connection anywhere in the world can use our online courses,” Harvard President Drew Faust said during a meeting to announce the plan.
MIT has offered a program called OpenCurseWare for ten years that makes materials from more than 2,000 classes free online. It has been used by more than 100 million people. In December, the school announced it also would begin offering a special certificate, known as MITx, for people who complete certain online courses. Harvard has long offered courses to a wider population through a similar program.
The MITx will serve as the foundation for the new learning platform.
MIT President Susan Hockfield said more than 120,000 people signed up for the first MITx course. She said Harvard and MIT hope other universities will join them in offering courses on the open-source edX platform.
“Fasten your seatbelts,” Hockfield said.
Other universities, including Stanford, Yale and Crnegie-Mellon, have been experimenting with teaching to a global population online.
The Harvard-MIT program will be monitored by a not-for-profit（非盈利的）organization based in Cmbridge, to be owned equally by the two universities. Bth MIT and Harvard have provided $30 million to start the program. They also plan to use the edX platform to research how students learn and which teaching methods and tools are most successful. 【題組】53.According to this text, edX is _______.
(A)a part of the free MIT OpenCurseWare

Plants are flowering faster than scientists predicted（预测）in reaction to climate change, which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns, scientists say.
Increased carbon dioxide（C2）in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’ reaction to climate change is a major challenge in ecology,” said the researches of several U.S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated（低估）the speed of flowering by 8.5 times and leafing by 4 times.
“Across all species, the experiments under-predicted the speed of the advance — for both leafing and flowering — that results from temperature increases,” the study said.
The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis（光合作用）to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0.8℃ since 1900, and nearly 0.2℃ every ten years since 1979.
So far, efforts to cut emissions（排放）of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century — a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels. 【題組】57.What is the key information the author wants to give in Paragraph 1?
(A)Plants’ reaction to weather could have damaging effects on ecosystem.
(B) The increasing speed of flowering is beyond scientists’ expectation.
(C) Cimate change leads to the change of food production patterns.
(D)Food chains have been seriously damaged because of weather.
