21、Saving lives has always been an important mission (使命) of science. Now science, and indeed all society, are facing a new dilemma: whether or not to try and save more lives through human cloning.
The first cloning experiments in the 1950s involved frogs and toads. It was not until 1997 that scientists successfully cloned the fist mammal, the now world-famous sheep known as Dolly. Cloning techniques’ have continued to improve since then, and today there are cloned mice, salmon, and cattle.
Some scientists want to apply the methods used in cloning animals to produce skin, or organs, and other body parts for humans. One of these methods involves taking adult cells from the brain or blood and growing them into new tissues. Another more complex technique takes embryo (胚胎) cells and develops them into a wide variety of cell types and tissues. It is this planned use of human embryos that has resulted in controversy (争议) and criticism.
The cloning of human cells provides the potential to find cures and eliminate diseases. The dream of some researchers is to create a Utopian world of good health. Others question whether it is right to “Play God” in an attempt to cure the disabilities and diseases in this world.
Some of the great hopes for cloning include the utility to perform transplants, whenever they are needed, using cloned organs. For example, people with lung cancer may simply have their lungs replaced with healthy ones. Scientists also look forward to the day when people in wheelchairs can walk again, and illnesses such as Alzheinmier’s and Parkinson’s Disease can be prevented.
However, a lot of people worry about the appearance of masses of identical people, and the production of “perfect” humans for warfare or slave labor. We might even see headless human bodies being stored at hospitals for their “spare parts”. With such thought-causing possibilities for the 2lst century, human cloning will no doubt continue to receive widespread attention and scrutiny (审视).
【1】What problem is science faced with?
A.Whether human cloning can help save more lives.
B.How to carry out human cloning scientifically.
C.Whether human cloning should be used for saving lives.
D.How to save more lives through human cloning.
【2】What can we know about cloning according to the text?
A.It has a history of over half a century.
B.I develops very quickly in the 21st century.
C.It can protect people from diseases of any kind.
D.It has enabled many people in wheelchairs to walk again.
【3】The underlined word “eliminate” in paragraph 4 most probably means “________”.
A.put up with
B.get along with
C.make up for
D.get rid of
【4】What can be inferred from the last paragraph?
A.Human body parts will be stored at hospitals for use.
B.Hunan cloning may become a trend in the 21st century.
C.Many people learn the effects of human cloning on our society.
D.People think humans will surely be cloned for slave labor.
22、When the need for information technology service arises, it can be a stressful moment—the user is locked out of their computer, or a program isn’t working properly. But if you ask anyone in the MIT departments of Chemistry and Physics, or the News Office—the Institute divisions that are fortunate enough to have Greg Walton as their IT service provider, they’ll acknowledge that not only is Walton the best, but whatever the issue is, he will see it through until all involved are satisfied with the outcome. Walton usually arrives on the scene with endless positive energy that transforms a technical annoyance into an enjoyable interaction, regardless of how many other IT fires he has already put out that day.
The qualities that make him a star employee extend far beyond the campus. After spending his early years in foster care, Walton lived with his great-grandmother, but mostly, he was left to support himself. While many children might, understandably, lie flat under such unsupervised circumstances, Walton excelled academically and athletically at high school. He became the first person in his family to graduate from high school, and enrolled in college.
Walton seized the chance to enroll in Year Up, a program aiming to close the “opportunity divide” by providing young adults with the skills, experience, and support that will empower them to reach their potential through professional careers and higher education. Walton remains an active ambassador for the organization.
In June of 2007,armed with shining recommendations, Walton was hired as a temp (临时工) at MIT.He eventually worked his way up to where he is today—an invaluable asset (不可或缺的人) to three departments.“I do feel lucky to work at MIT,” he says.“I’ve had the ability to tour the country sharing my story in hopes that some people may be inspired and employers may see young adults with tough backgrounds differently.”
In addition to Year Up, he is involved with a number of organizations committed to helping young adults overcome their troubled pasts. This desire to have a positive impact on people’s lives extends seamlessly into his work at MIT. “Giving back is very important to me,” Walton says. “So many people have invested their time and energy into helping me, so I feel it would be an injustice not to do so.”
【1】Staff members in MIT sing high praise for Walton mainly because________.
A.he enjoys interacting with his clients
B.he knows how to put out fires for others
C.he solves problems with a positive attitude
D.he is good at developing computer programs
【2】What do we know about Walton before he went to college?
A.He depended on his great-grandma for a living.
B.He stood out in study and sports in high school.
C.He lay flat just like other unsupervised children.
D.He was supported by foster care for better education.
【3】Why did Walton get involved with a lot of organizations?
A.To share his troubled past with young adults.
B.To pay back to society by helping young adults.
C.To advise businesses to treat young adults fairly.
D.To promote education equality among young adults.
【4】What can we conclude from Walton’s story?
A.One good turn deserves another.
B.Opportunities favor the prepared mind.
C.Education is a powerful weapon to change the world.
D.One’s future is defined by his efforts, not by his origin.
23、Like a phoenix (凤凰), some stars may burst to life covered in “ash,” rising from the remains of stars that had previously passed on.
Two fireballs covered in carbon and oxygen, ashy byproducts of helium fusion (氦聚变), belong to a new class of stars, researchers report in the March Monthly Notices. Though these burning objects are not the first stars found covered in carbon and oxygen, they are the first discovered to have helium-burning cores.
“That merger (并合) tells you the star must have evolved differently,” says study author Nicole Reindl.
The stars may have formed from the merger of two white dwarfs (白矮星), the remaining hearts of stars that exhausted their fuel, Reindl further explains. One of the two was rich in helium, while the other contained lots of carbon and oxygen. These two white dwarfs had already been orbiting one another, but gradually drew together. Eventually the helium-rich white dwarf “ate” its partner, leaving carbon and oxygen all over its surface, just as a messy child might get food all over their face.
Such a merger would have produced a star covered in carbon and oxygen to burn nuclear fusion in its core again, says Tiara Battich, a German astrophysicist.
To test this idea, Battich copied the evolution, death and eventual merger of two stars on his computer and simulated (模拟) the process. He found that putting together a carbon-and-oxygen-rich white dwarf and a more massive helium one could explain the compositions of the two stars observed by Reindl and her colleagues.
“But this should happen very rarely,” Battich says. In most cases the opposite should occur, because carbon-oxygen white dwarfs are usually the more massive ones. For the rarer case to occur, two stars slightly more massive than the sun must have formed at just the right distance and the right time.
The origins story Battich proposes demands a very specific and unusual set of circumstances, says Simon Blouin, a Canadian astrophysicist. “But in the end, it makes sense.”
【1】What’s the newest discovery of the merger of two stars?
A.It produces a mass of helium ash.
B.It possesses a helium-burning core.
C.It is covered in carbon and oxygen.
D.It makes an oxygen atmosphere for life.
【2】How did Battich prove his assumption of the merger?
A.By co-working with Rcindl’s team.
B.By making astronomic observations.
C.By building models on his computer.
D.By testing the two stars’ compositions.
【3】The underlined phrase “the opposite” means ________.
A.the carbon-oxygen white dwarf “ate” the helium one
B.the helium white dwarf “ate” the carbon-oxygen one
C.helium white dwarfs are usually the more massive ones
D.carbon-oxygen white dwarfs are usually the more massive ones
【4】What’s the main idea of the text?
A.The formation of stars makes sense.
B.The burning of stars brings them to life.
C.Stars inspire scientists to reflect on the universe.
D.Star mergers can unfold in more than one way.
24、 Futurism is all around us, even if we usually don't notice it. When it comes to the weather, forecasting is normal. When it comes to cultural or social predictions, though, futurism can feel more fantastical. But over the last decades, such forecasts have gradually become serious business, shaping our expectations and the world.
A range of professions - from sociologists to economic forecasters-have long devoted time and energy to predicting where the world might go. By the middle of the 20th century, futurology, or the study of the future, became more systematic as social scientists developed futurological methods. At the RAND Corporation, during the 1960s, strategists such as Herman Kahn established long-range planning techniques. Companies also involved themselves in encouraging the new study's rise. In 1967, Royal Dutch Shell began to experiment with scenario (情境)planning or the technique of using storytelling to speculate (推测) about the future. Called the Year 2000 study, Shell's earliest scenarios suggested that the company needed to plan for discontinuity, helping it to better deal with political and social changes that might impact its bottom line.
Faith Popcorn, who runs the futurist consulting firm BrainReserve, did something revolutionary in the 1970s and 1980s; Rather than predict product prices or sports scores, Popcorn and other futurists studied consumer culture. They realized that rapid cultural change could shake up what products people wanted. They studied human behavior and tracked new cultural developments to help imagine and design goods and services that were on trend, and soon consumers would see new things being marketed and sold. When BrainReserve predicted that more people would be staying home, Domino's made moves to dominate pizza delivery to unsocial customers. In 1982, John Naisbitt's best-selling book “Megatrends” predicted the trend of humanizing. Companies then made office spaces more open, or offered ATMs that asked “How are you” as a bank teller might.
Futurists and trend forecasters found a broad audience in the US for their predictions in the 1970s, and still do to this day. If anything, fast-paced technological changes, and current social and political issues, have increased people's appetite for where the world might go. And even when they get it wrong, forecasters continue to capture attention and market share-anyone today seems to have a burning desire to glimpse what the future might hold.
【1】What role did the Year 2000 study play?
A.It caused Shell to make wrong decisions.
B.It promoted the development of futurology.
C.It provided data for the RAND Corporation.

【2】How did BrainReserve help businesses?
A.It helped create new products.
B.It helped predict product prices.

【3】What is today's Americans attitude to future predictions?
A.Favorable.
B.Cautious.
C.Indifferent.
D.Uncertain.
【4】What is the text mainly about?
A.Different futurological methods.
B.Forecasters influence on culture.
C.The history of predicting the future.
D.Important changes in consumer culture.

26、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Ezri and Oliver were so keen to climb the mountain that they begged to join their dad Brandon for another hike. Just after 8 a. m. on a beautiful Sunday morning, they set off. Brandon’s backpack held his phone, Clif bars (能量棒), packets of apple sauce, apples, water bottles and fishing gear.
Brandon had planned a varied route up the mountain. The winding upward slope was fun and uneventful. Near the top, thick snow blanketed the path. Excitedly, the kids raced across the hard surface. They shared the second-last Clif bar and rested for an hour. Brandon looked around. His phone showed 1:30 p. m. and no signals.
When the kids started down, Brandon said, “You guys really want to find those fishing lakes, don’t you?”
“Oh, yes!” Ezri said. So they took an unfamiliar route down the other side of the mountain.
By the time Brandon realized the path had become an animal trail alongside a stream, it made sense to keep following it. The stream sang to them, and they kept following it down. Mid afternoon, when the sun disappeared behind heavy gray clouds, they suddenly felt lost, cold and hungry. For half an hour they cautiously moved downward until they reached a steep cliff (悬崖) edge. The stream became a noisy, six-metre waterfall. Mist enveloped them as the water raced over a huge rock.
Brandon cursed (咒骂) himself for taking an unknown route down. They held hands and inched down until Oliver slid on a loose rock and all three went flying.
Brandon wiped blood from his forehead and gathered his senses. Was anyone hurt? Oliver, crying and shivering, seemed okay. Ezri was weeping, but she too appeared uninjured. Brandon himself didn’t feel anything worse than the wound on his forehead. The backpack was stuck in the rocks six meters away. He saw no use trying to find it back. The air was cold and getting colder. They were wet and tired.
注意:
1.所续写短文的词数应为150左右;
2.请按如下格式在答题卡的相应位置作答。
To save the kids, Brandon realized he had to look for a way out alone.
