21、 From talking robots and video phones to rovers on Mars, technology has become so advanced that the previously impossible seems to occur on a daily basis. And yet – we still have no cure for the common cold.
Why can’t we stop the common cold? According to Peter Barlow, a scientist at Edinburgh
Napier University in the UK, the main challenge lies in the many different types of cold viruses that are produced by the rhinoviruses (鼻病毒). There are at least 160 types. They mutate (突变) so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isn’t likely to work on every type of cold.
However, researchers from Stanford University and the University of California, San Francisco, have found a possible answer. They discovered a protein that the viruses need. Without it, they can’t spread inside your body.
To identify the gene which produces the specific protein needed by the viruses, researchers used a gene-editing technique to test all genes in the human genome (基因组) one by one for thousands of cells. These modified (改变的) cells were then exposed to a range of enteroviruses(肠病毒), including the rhinoviruses which cause the common cold. All the viruses were unable to replicate (复制) inside cells without a gene that produces a specific protein, called methyltransferase SETD3.
Then, they tested genetically modified mice, which were completely unable to produce the protein. The mice were able to live healthy, normal lives without the protein. “Lacking that gene protected the mice completely from viral infection.” associate professor Jan Carette, from Stanford, told the BBC. “These mice would always die, but they survived and we saw a very strong reduction in viral replication and very strong protection.”
Carette said the plan is to find a drug which can temporarily suppress (抑制) the protein, instead of producing genetically modified humans. “We have identified a fantastic target that all enteroviruses and rhinoviruses require and depend on. Take that away and the virus really has no chance.” said Carette. “This is a really good first step – the second step is to have a chemical that mimics (模拟) this genetic deletion.” he added.
【1】What does Peter Barlow think is the main problem for prevention of the common cold?
A.The slow mutation of some genes.
B.The fast speed at which rhinoviruses spread.
C.The wide variety of cold viruses created by rhinoviruses.
D.The harm rhinoviruses do to the immune system.
【2】What can we learn about the protein needed by the viruses?
A.It allows the viruses to mutate easily.
B.It helps the viruses replicate inside our bodies.
C.It helps the viruses become resistant to drugs.
D.It accelerates the speed at which the viruses spread.
【3】What did the researchers discover in their gene-editing study?
A.The modified cells seemed to protect the mice against viral infections.
B.Genetically modified mice died because they lacked the protein.
C.More methyltransferase SETD3 was produced after the cells were modified.
D.The gene-editing technique was more effective against enteroviruses than rhinoviruses.
【4】What do the researchers most probably do next, according to Carette?
A.Conduct experiments on genetically modified humans.
B.Apply this gene-editing technique to control other viruses.
C.Identify a drug that can help reduce the protein.
D.Find a chemical that can cure all enteroviruses and rhinoviruses.
22、I’ve just asked Julie Gray, a biologist at the University of Sheffield, which species she thinks would be the last ones standing if we don’t take transformative action on climate change. “I don’t think it will be humans. I think we’ll go quite early on,” says Gray. Humans probably won’t be among the survivors, partly because humans produce young extremely slowly and generally just one or two at a time.
It may seem like just a thought experiment. But discussing which species are able to survive climate change is disturbingly concrete. As a report stated recently, one in four species currently faces extinction, which is closely linked to climate change. While the seriousness of climate change is undeniable, we can make some educated guesses about which species will have a better shot at going far.
According to Jen Lau, a biologist at University Bloomington, heat tolerant and drought resistant plants, like those found in deserts, are more likely to survive. So are plants whose seeds can be spread over long distances, for example by wind or ocean currents. Plants that can adjust their flowering times may also be better able to deal with higher temperatures.
We can also look to history as a guide. Cockroaches adapted to an increasingly dry Australia tens of millions of years ago, by starting to dig holes in soil to hide. Cockroaches also tend to not be picky eaters. Having broad diets means that climate change will be less of a threat to them.
Furthermore, species called “mobile generalists” by experts can move and adapt to different environments and are more likely to last long in face of climate change. For example, deer in the US are common in suburban areas and manage to live where forests have been removed or are regularly disturbed.
Certainly, some animals would also survive if they could find a buffer: an area that is relatively protected from climate change’s consequences, such as deep sea canyons, underground caves.
【1】What does the author probably think of the answer given by Gray?
A．Ridiculous.
B．Unreasonable.
C．Upsetting.
D．Exciting.
【2】Which of the following can replace the underlined part in Paragraph 2?
A．Peacefully wait.
B．Quickly die out.
C．Greatly change.
D．Possibly survive.
【3】Which of the following species is likely to survive climate change?
A．Trees growing in the rainforest and flowering at fixed time every year.
B．Animals good at digging holes and not particular about food.
C．Creatures mainly living in trees and spending most time sleeping.
D．Fishes that do not enjoy deep diving and like to stay in a bay.
【4】Which of the following is the best title for the text?
A．How Climate Will Change in the Future
B．What Species May Survive Climate Change
C．Why Some Species Have Broader Diets
D．Where Species Can Hide in Climate Change
23、New words emerge in English all the time. In fact, in recent years more new words and phrases are entering the language than ever before, partly due to the increased willingness of lexicographers (词典编纂者) to include them in the dictionaries.
John Algeo who studies the history of language says, “As our culture changes, the language changes. American culture is going through a time of rapid change.”
Technology is moving fast, which has a big effect on language. The computer world produces hundreds of new words. New terms also come from business, medicine, and other fields.
Many new English words come from other languages. David Jost helps create the American Heritage Dictionary. “We constantly borrow words from other cultures,” he says. “This will go on forever in cultures.”
“People in many parts of the world speak English now. That is another reason why so many new words are entering the language,” says Algeo.
The American Dialect Society has a contest each year. The society selects a “new word of the year”, which gains high level of popularity on media for some days. Last year the winner was “information superhighway”, referring to a whole set of electronic network of information and people getting access to this network by computer.
New words often come in several forms, such as the back-formation (like enthuse from enthusiasm), the clipping (like zoo from zoological garden), and the compounding, etc. Over time, one form tends to win out. Take the compounding for instance. “Domestic partners” has been growing popular lately, even though many terms have been used to describe couples who live together but are not married.
“A new word rarely can be traced to one source,” says Algeo. “Several people fend to create a new word when a need for one exists.”
“Most new words have a limited life ‘span’,” say language experts. Only a few will survive through the next 100 years.
【1】What might have least effect on English language?
A．Culture.
B．Technology.
C．Other languages.
D．Language contests.
【2】What does the writer want to demonstrate by mentioning “domestic partners”?
A．It is a compounding word.
B．New words often come in several forms.
C．Over time, one form tends to win out.
D．A new word rarely can be traced to one source.
【3】What can we learn from the passage?
A．New words occur all of a sudden.
B．New words will become old or extinct.
C．Information technology helps the American Dialect Society.
D．American culture changes rapidly as well as English language.
【4】What’s the best title of this passage?
A．New Words Developing Naturally
B．English Language Changing Rapidly
C．English Vocabulary in a State of Development
D．New Words Influencing English Language
24、Modern inventions have speeded up people’s loves amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boats (吹嘘) of saving precious seconds in handling tasks.
All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind on another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientist; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.
However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.
There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestor faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence.

D. the manufactures boast a lot
【2】What does ＂the days＂ in Paragraph 3 refer to ?
A. Imaginary life. B. Simple life in the past.
C. Times of inventions. D. Time for constant activity.
【3】What is the author’s attitude towards the modern technology?
A. Critical B. Objective.
C. Optimistic. D. Negative.
【4】What does the passage mainly discuss?
A. The present and past times.
B. Machinery and human beings.
C. Imaginations and inventions.
D. Modern technology and its influence.

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。
We were in our late 20s with a child when my husband, Ralph, finally graduated from college.
“OK, now I deserve a piano,” I blurted out when he sat down for lunch just before the graduation ceremony. A look of surprise crossed his face.
“We could never afford a piano. After so many years of hard work, we got you through school. Now I deserve a piano,” I repeated.
Several months later, Ralph, with help, moved the upright piano we bought for $ 100 into our cottage’s tiny arched dining room. It smelled a little musty, but had great tone.
Ralph started graduate school, leaving no money for private piano lessons. The first thing that came to my mind was Santa Monica City College—maybe it offered piano lessons. Skimming the catalog, I danced around the room when I found a class at the same time the boys were at preschool.
Practicing, however, was not so easy. Four-year old redheaded Denny crawled out of bed in the evening on a regular basis. That was my time to practice. He’d pad out of the bedroom in his sleeper and climb up on the bench with me. Soon he began plinking (发出叮铃声) on the high keys. I tried to ignore him. He listened to the echoes of the keys and plinked some more. Doing all I could do to keep focused on my own practicing, I continued to ignore him.
This practice pattern became an evening routine. After a while, I didn’t even hear him anymore. Ralph studied. Denny plinked on the high keys, and I focused on my piece for the end-of-the-term recital (独奏会).
That evening came. However, Ralph said he was busy preparing for the midterms and couldn’t watch Denny.
Pacing back and forth, I shook my head trying to figure out what to do. Time was running out. I bundled up Denny—with his sleeper on—and drove off to the recital with him.
“We’ll sit in the front row, Denny,” I whispered. “You have to be very quiet and listen when I am playing.” He nodded, said “Uh-huh,” and we sat down.
注意：
1. 续写词数应为150左右;
2. 请按如下格式在答题卡的相应位置作答。
Denny held my hand, but then my turn came.
