8．It wasn't _______ he took off her mask _______ I recognized he should be a famous film star．（　　）

A．

when； that

B．

until； when

C．

until； that

D．

when； then

分析直到他摘下她的面具，我才认出他应该是一位著名的电影名星．

解答答案：C 考查强调句．not until he took off her mask是强调部分，要用连词that．故选C．

点评英语中常用的强调句（又称分裂句）结构是"it is/was+被强调部分+who/that…"．使用强调句型时必须注意以下几点：1．如果原句子中的谓语动词为现在时或将来的各种时态，变为强调句型时，就用"it is …"；如果原句子中的谓语动词为过去的各种时态，变为强调句型时，就用"it was…".2．被强调的部分是人称代词时，原句用什么格，强调句也用什么格；如果是人称代词主格，who/that后的动词在人称和数上应与主格人称代词保持一致．3．关于强调句的连词选用，强调人时可以不用that，而用who来代替．强调宾语时，如果指的是人，可用whom．如果不强调人一律用that．切不能与定语从句和主语从句相混淆而错误地使用what，how，which，where，when，why．

18．"If we can set it up so you can't unlock your phone unless you've got the right fingerprint（指纹），"Barack Obama asked last Tuesday，"why can't we do the same thing for our guns？"For this reasonable-sounding question，the president was applauded throughout the media．
As it happens，though，there is a good answer to this question：there is no market for guns that work just some of the time．Guns are simple things designed to operate as easily and reliably as possible．The introduction of electronics eats away this simplicity，and to a degree that is absolutely unacceptable to the consumer．As President Obama well knows，the fingerprint software on his phone works rather erratically：Often it takes a user two or three tries to log in； occasionally，it falls asleep deeply and obeys the password．When this happens on an phone，the user is mildly inconvenienced．If this were to happen on a gun，the user would be dead．There is a reason that modern smartphones put the camera function outside of the authentication（认证） process．
How could we possibly think that guns are the same as other commercial products？It is true that，say，cars have become considerably safer over the last few decades； true，too，that"research"has contributed to this improvement．But it matters enormously that a car is not intended to hurt people，and that in a perfect world nobody would ever be injured by one．Can we say the same of guns？Of course not．Guns are killing machines，designed explicitly to do damage to living things．In fact，they have no other purpose．As such，the salient question before any free people is not"are guns dangerous？"，they are，but"who gets them，and why？"
This is not to say that nothing at all can be done to improve public safety．On an individual level，gun owners should do everything to ensure that their guns are kept away from children，and，where possible，they should train themselves in case they are ever called upon to shoot in anger．At the national level，the combination of better policing and economic growth can help to reduce crime-and，indeed，it has．In 1993，gun crime was more than twice as common as it is now，and there were many fewer guns in circulation．Ugly as it is in its own right，that we have reached the point at which two-thirds of all guns-related deaths are deliberately self-inflicted is a small victory．
How to address those deaths that remain？That is a tricky one．I do not know the answer，and nor，frankly，does anybody else．But selling fantasies to the ignorant is not going to cut it．
67．What does the writer mainly argue in this passage？B
A．Gun crime has been greatly reduced．
B．The idea of smart guns is not realistic．
C．Gun control will not succeed in America．
D．Guns-related deaths deserve public attention．
68The underlined word"erratically"in Paragraph 2probably meansC．
A．with effectiveness
B．with passion and energy
C．in an unpredictable manner
D．in a reasonable and fair way
69．The writer supports his ideas in Paragraphs 2and 3mainly byD．
A．analyzing statistics
B．presenting problems and solutions
C．quoting the authorities
D．making comparisons and contrasts
70．Which of the following might the writer NOT agree with？A
A．Few know how to deal with guns-related deaths．
B．Efforts to improve public safety have partly paid off．
C．The nature of guns distinguishes them from other products．
D．Guns using fingerprint software can risk the lives of the users．

3．If I asked you to sit down  and remember a list of phone numbers or a series of facts，how would you go about it？There's a fair chance that you'd be doing it wrong．
One of the interesting things about the mind is that even though we all have one，we all have one，we don't have perfect insight（洞察力） into how to get the best from it．This is partly because of flaws（缺陷） in our ability to think about our own thinking．Studying this self-reflective thought process exposes human being'personal blind spots．
One area there these blind spots are particularly large is learning．We're actually surprisingly bad at having insight into how we learn best．
Researchers Jeffrey Karpicke and Henry Roediger IIII made an experiment，where they asked college students to learn pairs of Swahib and English words．So，for example，they had to learn that if they were given the Swahili word"mashua"the correct response was"boat"．They could have used the sort of facts you might get on a high-school quiz，but the use of Swahili meant that there was little chance their participants could use any background knowledge to help them learn．After the pairs had all been learnt，there would be a final test a week later．
Now if many of us were revising this list we might study the list，test ourselves and then repeat this cycle，dropping items we got right．This makes studying and testing  quicker and allows us to focus our effort on the things we haven't yet learnt．It's a plan that seems to make perfect sense，but that is disastrous if we really want to learn properly．
Karpicke and Roediger asked students to prepare for a test in various ways，and compared their success---for example，one group kept testing themselves on all items without dropping what they were getting right，while another group stopped testing themselves on their correct answers．On the final exam differences between the groups were dramatic．While dropping items from study didn't have much of an effect，the people who dropped items from testing performed relatively poorly．
It seems the effective way to learn is to practice getting items back from memory，not trying to consolidate（巩固） them in there by further study．Moreover，dropping items entirely from you revision，which is the advice given by many study guides，is wrong．You can stop studying them if you've learnt them，but you should keep testing what you've learnt if you want to remember them at the time of the final exam．
So the evidence has a moral for teachers：there's more to testing than finding out what students knows--tests can also help us remember．
67．According to the passage，we often fail to remember facts becauseD．
A．we ignore our weakness in memorizing things
B．we don't understand well what we are learning
C．we don't know where our metal blind spots are
D．we take improper ways to memorize for good ones
68．The researchers'experiment was intended toB．
A．confirm we don't know how to learn effectively
B．find out how we can consolidate our knowledge better
C．distinguish effects of memory in learning different languages
D．prove the importance of background knowledge in memorizing．
69．What does the authour believe leads to a good memory？A
A．Constant measure of your knowledge．
B．Frequent revision of what you learn．
C．Firm abandonment of what you're poor at．
D．Strong desire fr grasping new knowledge．

13．http://www．newscientist．com/article/dn26694-humans-and-birds-share-the-same-singing-genes．html#．VIrqUPSl-cs
It's not just great minds that think alike．Dozens of the genes involved in the vocal learning that underpins human speech are also active in some songbirds（黄莺）．And knowing this suggests that birds could become a standard model for investigating the genetics of speech production and speech disorders．
Complex language is a uniquely human trait，but vocal learning-the ability to pick up new sounds by imitating others-is not．Some mammals，including whales，dolphins and elephants，share our ability to learn new vocalizations（发声）．So do three groups of birds：the songbirds，parrots and hummingbirds．
The similarities between vocal learning in humans and birds are not just superficial．We know，for instance，that songbirds have specialised vocal learning brain circuits that are similar to those that mediate（传达） human speech．
What's more，a decade ago we learned that FOXP2，a gene known to be involved inhuman，is also active in"area X"of the songbird brain-one of the brain regions involved in those specialised vocal learning circuits．
AndreasPfenning at the Massachusetts Institute of Technology and his colleagues have now built on these discoveries．They compared maps of genetic activity in brain tissue taken from the zebra finch，budgerigar and Anna's hummingbird，representing the three groups of vocal-learning birds．
They then compared these genetic maps with others taken from birds and primates that can't learn new vocalisations，and with maps taken from the brains of six people who donated tissue to the Allen Brain Institute in Seattle．
Their results showed that FOXP2is just one of 55genes that show a similar pattern of activity in the brains of humans and the vocal-learning birds．Those same genes show different patterns of activity in the brains of animals incapable of vocal learning．
"The similarities are beyond one or a handful of genes，"says Pfenning．"There are just systematic molecular similarities between song-learning birds and humans．"
"There's potential for songbirds to be used to study neurodegeneration（神经元退变）-especially conditions like Huntington's，"says Pfenning．Huntington's disease affects the ability to produce complex motor behaviour，such as singing and talking，so experiments with birds might implicate particular genes in the disease．
Constance Scharff at the Free University of Berlin in Germany，who helped identify the importance of FOXP2 forvoca agrees that songbirds can make great models for human speech and its pathologies（病理学）．"My lab's research during the past 10years has shown that FOXP2is as relevant for birds'song learning as it is for human speech learning，"she says．
61．Which of the following is WRONG according to the passage？C
A．The songbirds，parrots and hummingbirds imitate humans．
B．FOXP2is active in one of the brain regions of the songbird brain．
C．Songbirds have the same vocal learning brain circuits as human．
D．FOXP2is a gene that is known to be involved in human language．
62．The underlined word"underpin"in the first paragraph probably meansB．
A．increase
B．support
C．prevent
D．decrease
63．What can we infer from the passage？C
A．FOXP2was involved in human language about 12years ago．
B．Six people donated brain tissue to the Allen Brain Institute in Seattle．
C．Experiments with songbirds are likely to help cure Huntington's disease．
D．Constance Scharff discovered at the Free University of Berlin．
64．What is the passage mainly about？B
A．Birds have different genes from humans．
B．Humans and birds share the same singing genes．
C．How FOXP2affects the brains of humans and birds．
D．Experiments with birds can cure the disease of humans．

20．In 1751，Swedish botanist Carolus Linnaeus came up with the novel idea of using flowers as clocks．Morning glories open their trumpet-like petals（花瓣）around 10a．m．，water lilies at 11and so on through evening primroses and moonflowers．A full layout of these blossoms，planted in a circle，could indicate the time．It was an unusual notion．But some 250years later，scientists are seriously interested in the timekeeping mechanisms of nature．"They're so ubiquitous； they're almost a signature of life，"says molecular neuroscientist Russell Foster of Imperil College，London．
From cockroaches to humans，Foster explores these internal clocks in a fascinating new book，Rhythm of Life，co-authored with British science writer Leon Kreitzman．The author shows how the daily patterns known as circadian rhythms influence far more than our sleep．Heart attacks are more common in the morning．Women tend to go to labor（分娩前阵痛）in the evening．Severe asthma（哮喘）occur at night．Although we may jet across time zones，circadian rhythms rule．The book traces the century-long quest to uncover their mechanisms，with some starting outcomes-including the recent discovery that certain genes switch on and off in 24hour cycles．Even our responses to medicines may depend on when we take them．
Nature has devised internal clocks for a simple reason：they aid survival．"The early bird really does get the work，"-thanks to a silent wake-up call before dawn．A mimosa plant spreads its fernlike leaves during the day to create the maximum surface area for photosynthesis，and then folds them up at night to reduce water-vapor loss．It's not a mere response to light．"They do this even when kept in the dark，"says biologist Eugene Maurakis of the Science Museum of Virginia．
In humans，the master clock is a tiny clump of cells in the brain called the suprachiasmatic nuclei．The clock is reset daily by signals from a novel type of photoreceptor in the eye that Foster discovered．"The blind rely on it，too，provided their eyes haven't been removed，"he says．The result is an orchestrated series of biological events that unfolds in sequence．In the hours before breakfast，the body releases digestive enzymes（酶）gradually to be ready for the first meal．Temperature and blood pressure rise in preparation for the day's demands．This helps explain the morning increase in the heart attacks．Cells reproduce at set times．Hormones rise and fall-many of them according to a predetermined schedule．
The implications for medicine are profound．By timing treatments to complement daily changes in biochemistry，the author argues，we can boost efficacy and reduce side effects．In one seminal trial，medical oncologist William Hrushesky of the Dorn V．A．Medical Center in Columbia，S．C．，found that by simply reversing the times when he administered two chemotherapeutic drugs，he could extend survival in women with advanced ovarian cancer from 11percent at five years to 44．According to Chronobiology International，more than a dozen ailments can currently benefit from carefully timed treatments．In one recent study，he notes something as simple as low-dose aspirin at bedtime reduced the rate of preterm deliver in pregnant women at risk for hypertension（高血压、过度紧张）from 14percent to zero．Aspirin in the morning had little effect．Surprised？No to Foster and Kreitzman．As they show，timing is everything．
39．According to the book Rhythms of Life，which of the following is TRUE？B
A．Severe asthma is not common at night．
B．Circadian rhythms influence us in various aspects．
C．It's written by Russell Foster，a famous molecular neuroscientist．
D．Medicines always function well provided that they have little side effects．
40．From the passage，we know that the mimosa plantC．
A．unfolds its leaves to avoid light．
B．folds leaves to take in water at night．
C．devises internal clocks in order to survive．
D．stops using internal clocks when placed in the dark．
41．The underlined word"ailments"in the last paragraph is closest in meaning toA．
A．diseases．
B．patients．
C．hypertensions．
D．treatments．
