In a great many cities, hundreds of people ride bikes to work every day. In New York, some bike riders have even formed a group called Bike for a Better City . They declare that if more people rode bikes to work, there would be fewer automobiles in the downtown part of the city and so less dirty air from car engines.
For several years this group has been trying to get the city government to help bike riders. For example , they want the city to draw special lanes( 车道) for bikes on some of the main streets, because when bike riders must use the same lanes as cars there are accidents. Bike for a Better City feels that if there were special lanes, more people would use bikes.
But no bike lanes have been drawn. Not everyone thinks it is a good idea- they say it will slow traffic. Some store owners on the main streets don’t like the idea- they say that if there is less traffic, they will have less business.
The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park, the largest place of open ground in New York, is closed to cars, and the roads may be used by bike only.
But Bike for a Better City says that this is not enough and keeps fighting to get bike lanes down-town. In New York, a group of bike riders_________.
| A．are keeping practicing for health |

| A．they will make cars and buses run slowly |
| B．they will make it easier for bike riders to go to parks |
| C．they will make the city more beautiful |
| D．they will prevent accidents |
The government has not decided whether special lanes should be drawn_______.
| A．so that everyone is disappointed |
| B．because there are different opinions |

Like any good mother, when Karen found out that another baby was on the way, she did what she could to help her 3-year-old son, Michael, prepare for a new sister. And day after day, night after night, Michael sang to his sister in Mommy’s tummy(肚子).
Everything was normal for Karen. But she had difficulty giving birth to the baby. Finally, Michael’s little sister was born. But she was in serious condition and was sent to hospital at once. The days went by. The little girl got worse. The doctor told the parents, “There is very little hope. Be prepared for the worst.”
Karen and her husband had fixed up a special room in their home for the new baby—now they planned a funeral. Michael, kept begging his parents to let him see his sister, “I want to sing to her,” he said.
Karen knew if he didn’t see his sister now, he would never see her alive. She led Michael to his sister’s bedside. In the pure-hearted voice of a 3-year-old, Michael sang: “You are my sunshine, my only sunshine; you make me happy when skies are gray…”
Immediately the baby girl responded. Her breath became calm. “Keep on singing, Michael!” ‘You never know, dear, how much I love you. Please don’t take my sunshine away…” Tears ran down Karen’s face.

Machu Picchu is considered to be a truly extraordinary archaeological(考古学的) discovery and is one of South America’s largest tourist sites. As many as one thousand visitors visit the ancient Incan（印加文化的） ruins daily. What draws vacationers and adventurers to this remote location high in the Andes Mountains of Peru（秘鲁）? A large part of the attraction is the mysteries that surround Machu Picchu. For example, Machu Picchu is considered “the lost city” of the Incas because it was never found by Spanish invaders and was known to only a few local peasants for almost four hundred years.
The “city in the clouds”, Machu Picchu’s lasting beauty comes from the careful blending of its striking architecture with its mountaintop environment. Its greatest skill shows are in the stone structures, which equals that of the ancient Egyptians. The stone blocks were so appropriately cut that they fit together without the need for mud. The largest stones at Machu Picchu weigh as much as fifteen tons! It has been difficult to explain how the huge blocks were transported. The buildings, including many that have survived lots of earthquakes, contain stones which interlock so perfectly that a knife cannot be forced between them. When compared to other ancient civilizations, it is difficult to understand how Machu Picchu could have been missed by the Spanish and lost from history for four hundred years.
For many of the mysteries of Machu Picchu being unsolved, it is clear why Machu Picchu remains “the most famous ruins in all of South America”. Which of the followings is NOT a mystery of Machu Picchu?
| A．Machu Picchu is called the “city in the clouds”. |
| B．Machu Picchu remains “the most famous ruins of South America”. |
| C．Machu Picchu is “the lost city” of the Incas. |
| D．Machu Picchu is the largest stone city of the world. |

| D．make the ancient Incan ruins known |
There once lived a rich businessman who had a lazy son. The businessman wanted his son to realize the value of labour and said: “Today, I want you to go out and earn something, failing which you won’t have your meals tonight.”
He went crying straight to his mother. Her heart melted at her son’s eyes. She gave him a gold coin. When the father asked his son what he had earned, the son presented him the gold coin. The father asked him to throw it into a well.
The next day, he asked his son to earn something. This time he went crying to his sister who gave him a coin. When he showed it to his father he again asked him to throw it in a well. Then the father asked him to earn more money.
This time since there was no one to help him, the son was forced to go to the market. One shopkeeper told him he would pay him two coins if he carried his trunk to his house. He did so and sweated plenty. As he returned home he was asked to do the same. The son almost cried out. He could not imagine throwing his hard-earned money like this. He cried, “My entire body is aching. You are asking me to throw the money into the well.”
At this moment, the businessman told him one feels the pain only when the fruits of hard labour are wasted. On the earlier two occasions he was helped and therefore had no pain in throwing the coins into the well. The son had now realized the value of hard work. He promised never to be lazy and to safely keep the father’s wealth.

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（CO2）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.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．Climate change leads to the change of food production patterns. |
| D．Food chains have been seriously damaged because of weather. |
We can learn from the study published on the Nature website that ______.
| A．plants’ flowering is 8.5 times faster than leafing |
| B．there are 1,634 plant species on the four continents |
| C．scientists should improve the design of the experiments |
| D．the experiments failed to predict how plants react to climate change |
Scientists pay special attention to the study of plants because _______.
| A．they can prove the climate change clearly |
| B．they are very important in the food chains |
| C．they play a leading role in reducing global warming |
| D．they are growing and flowering much faster than before |
What can be inferred from the last two paragraphs about the world’s temperature?
| A．It has risen nearly 0.2℃ since 1979. |
| B．Its change will lead to weather extremes. |
| C．It is 0.8℃ higher in 1979 than that of 1990. |
| D．It needs to be controlled within 2℃ in this century. |
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.
Beginning 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 OpenCourseWare 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 Carnegie-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 Cambridge, to be owned equally by the two universities. Both 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.According to this text, edX is _______.
| A．a part of the free MIT OpenCourseWare |
