18."If we can set it up so you can't unlock your phone unless you've got the right fingerprint(指紋),"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(認(rèn)證) 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.a(chǎn)nalyzing 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.

分析 本文主要講述了奧巴馬提出使用指紋識別技術(shù)來控制槍支,作者在本文中對于這一做法提出自己的觀點(diǎn),認(rèn)為這一建議并不實(shí)用.

解答 67.B 推理判斷題.根據(jù)第二段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.如果指紋識別技術(shù)有時候會失靈,要多次嘗試,不會給人帶來生命危險.但是如果控制槍支的識別技巧出現(xiàn)了問題,就會導(dǎo)致人們死亡.可知作者認(rèn)為通過指紋智能控制槍支的做法并不現(xiàn)實(shí).故B正確.
68.C 詞義猜測題.根據(jù)劃線詞后一句Often it takes a user two or three tries to log in; occasionally,it falls asleep deeply and obeys the password.有時候手機(jī)用戶會多次嘗試指紋識別才能使用手機(jī),有時候手機(jī)還會死機(jī),需要使用密碼開機(jī).也就是說指紋識別的方法有難以預(yù)測的問題.所以該詞指C項(xiàng)含義.
69.D 寫作手法題.作者在第二段中把指紋識別使用手機(jī)的方法與控制槍支的進(jìn)行對比和比較,提出奧巴馬的建議并不實(shí)用.故D正確.
70.A 細(xì)節(jié)理解題.根據(jù)第二段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.可知C項(xiàng)說法正確.根據(jù)第二段When this happens on an phone,the user is mildly inconvenienced.If this were to happen on a gun,the user would be dead可知D項(xiàng)正確;根據(jù)倒數(shù)第二段In 1993,gun crime was more than twice as common as it is now,and there were fewer guns in circulation.可知B項(xiàng)正確;根據(jù)最后一句But selling fantasies to the ignorant is not going to cut it.可知不要把槍賣給那些對于使用槍支無知的人是控槍很重要的方法,這也是很多人都知道的.故A項(xiàng)說法錯誤.

點(diǎn)評 本文是一個人生感悟類閱讀理解,題目涉及多道細(xì)節(jié)理解題,做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進(jìn)行仔細(xì)分析,結(jié)合選項(xiàng)選出正確答案.推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案,切忌胡亂猜測,一定要做到有理有據(jù).

8.Owls are equipped with highly developed stealth technology (隱形技術(shù)) that helps them charge towards prey-an animal hunted and eaten by another-undetected,a study has shown.
Owls have flight feathers that absorb aerodynamic sound and control the vibrations (振動) that occur when a bird beats its wings.The result is perfect silence as it approaches a mouse or other prey.
Scientists used lasers and high-speed cameras to analyze and compare long-eared owl,eagle and pigeon feathers during flight.While differing in size,all three birds have a similar wing-beat style.
Professor Jinkui Chu led the research.He said,"Many owls have a unique and fascinating ability to fly so silently that they are out of their prey's hearing range,due to their feather structure."
This behaviour has long been of interest to engineers,as we seek to apply the owls'noise-reduction mechanisms (機(jī)制) to other purposes and situations that benefit society.
Now,however,we know the owls'silent flight ability is even better than we thought.Of all birds the owl is the king of acoustic stealth.It not only manages to prevent aerodynamic noise when gliding,but also mechanical noise caused by vibration during flying.
This is remarkable,considering the sudden jumping,bending and twisting the wings are subjected to when flapping and the noise that is created by other birds.
In the scientific world,the process used to remove this mechanical noise is called'damping',which means the removal of mechanical energy from a vibrating system usually by changing it into heat and allowing it to remain steady.
"Our research showed the long-eared owl has superior damping skill,meaning it can remain amazingly stable and remove mechanical noise caused by the movement of its feathers-quite an impressive achievement of engineering.99
He added,"This study will hopefully provide further insight into the owls'silent flight mechanism and help engineers develop ideas for special materials or structures,such as on-shore wind turbines,where similar noise removal can be applied."

29.What can be true about owls according to the text?B
A.They are active during the day.
B.They attract much attention from engineers.
C.They have similar wings to eagles.
D.They beat wings without vibrations.
30.By saying"the owl is the king of acoustic stealth"in Paragraph 6,Jinkui Chu means owlsD.
A.a(chǎn)re good at capturing prey
B.have a good sense of hearing
C.a(chǎn)re good at jumping and twisting
D.have silent flight ability
31.What does the underlined word"it"in Paragraph 8refer to?C
A.Mechanical noise.
B.The vibrating system.
C.Mechanical energy.
D.The removal of mechanical energy.

7.Scientists have discovered a special biological behavior in dolphins(海豚) that could lead to a treatment for late-onset diabetes(晚發(fā)的糖尿。 in humans.Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding,but return to normal when they eat the following morning.
The extraordinary finding has led scientists to suggest that dolphins have"genetic switch"that allows them to imitate diabetes while they arenot feeding for a night,without suffering any ill effect.
If researchers can identify a similar genetic pathway in human,they may be able to develop drugs to effectively switch off diabetes.Some 2.2million people in Britain have type 2(or late-onset) diabetes,a figure that is expected to reach 4million by 2025as a consequence of rising levels of obesity(肥胖).
The tissuesof people with type 2diabetes have become resistant to insulin(胰島素)so they lose the ability to control sugar levels in their blood.The condition can damage the heart,eyes,kidneys(腎臟) and nerves and contribute to 5% of all deaths,according to the World Healthy Organisation.
Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare.Like humans,dolphins need some sugar in their blood for their brains to function normally.Venn-Watson's team analysed 1,000blood samples(樣本) from 52dolphins while theydidn't eat anything overnight and fed in the morning.At night time,the dolphins'metabolism(新陳代謝)changed greatly and showed similar characteristics to that seen in people with type 2diabetes.
"It is our hope that this discovery can lead to new ways to prevent,treat and maybe even cure diabetes in humans,"said Stephanie Venn-Watson,director of clinical research at the National Marine Foundation in San Diego.
72.What's the main idea of the passage?A
A.Humans get some ideaoftreatingdiabetes from dolphins.
B.Dolphins can switch into a diabetic-like state overnight.
C.Humans can suffer the same disease as dolphins.
D.Dolphins should be fed regularly to avoid diabetes.
73.The key to applying the finding to curing human diabetes lies inC.
A.producing insulin in a larger amount
B.developing drugs from healthy dolphins
C.identifying a similar genetic pathway in human
D.a(chǎn)nalysingmore blood samples from hungrydolphins
74.Which of the following statements is TRUE according to the passage?B
A.Scientists have found a similar genetic switch in humans.
B.More British people will suffer type 2diabetes due to obesity.
C.2.2million people with type 2diabetes die in Britain every year.
D.Dolphins imitate diabetes to avoid a high blood sugar level.
75.What will happen to dolphins if not fed for a night according to Venn-Watson?D
A.Their metabolism breaks down.
B.They become resistant to insulin.
C.Their heart and kidneys are damaged.
D.They keep high levels of blood sugar.
