篇一:英语科普:螳螂虾前爪杀伤力巨大

The miniweight boxing title of the animal world belongs to the mantis1 shrimp2, a cigar-sized crustacean3 whose front claws can deliver an explosive 60-mile-per-hour blow akin4 to a bullet leaving the barrel of a gun. Now, a Duke University study of 80 million years of mantis shrimp evolution reveals a key feature of how these fast weapons evolved their dizzying array of shapes -- from spiny5 and barbed spears to hatchets6 and hammers -- while still managing to pack their characteristic punch.

Duke researchers Philip Anderson and Sheila Patek studied nearly 200 mantis shrimp specimens7 representing three dozen species.

Mantis shrimp use a system of biological springs, latches8 and levers to power their fast strikes, enabling them to strike much more swiftly than would be possible with muscle power alone.

The team took careful measurements and calculated each specimen's ability to transmit muscular force and motion to the part of the claw that swings out to smash or spear their prey9 -- a mechanical property known as kinematic transmission.

When the researchers mapped their measurements onto the mantis shrimp family tree, they discovered that certain parts of the claw were more strongly associated with changes in strike mechanics than others -- enabling the other parts to evolve relatively10 independently without compromising the mantis shrimp's award-winning wallop.

"This research sheds new light on how these amazing movements evolved," Anderson said.

It suggests that mantis shrimp claws were able to evolve so many shapes because their mechanical properties are more affected11 by changes in some parts than others -- a pattern the researchers call "mechanical sensitivity."

The Book Of Life

So far,scientists have named about 1.8 million living species(物种),and that’s just a small number of what probably exists on Earth.With so many plants,animal,and other living things covering the planet,it can be tough to figure out what type of grass is growing by the roadside or what kind of bird just flew by.

A soon-to-be-started Web site might help.An international term of researchers has announced the creation of Web-based Encyclopedia(百科全书) of Life (EoL).The project aims to list every species on Earth in a single,easy-to-use reference guide.

To get the encyclopedia started,the creators will use information from scientific databases(数据库)that already exist.And eventually,in special sections of the site,non-scientists with specialized knowledge will come to helf.Bird-watchers,for example, will be able to input what birds they’ve seen and where. To make sure the encyclopedia is accurate, scientists will review much of the information added to it.

As the EoL develops,you might find it useful for school. Projects,The site will feature(以

。。。。。。为特色) special pages for kids who are studying ecosystems in their neighborhoods.Another convenient feature of the EoL is that you’ll be able to pick the level of detail you want to see to match your interests,age,and knowledgs.

It now takes years for scientists to collect all the data they need to describes and analyze species.The creators of the Encyclopedia of Life hope that their new fool will speed up that process.

60.The Web based EoL aims to ___ A. fine out what covers the earth B. list all living things on Earth C.work out the number of birds D.save the existing plants

61.One characteristic of the EoL is that ____ A. it is run by school students

B. it focuses on different types of grass

C. it provides different levels of information D.it allows non-scientists to review its data

62. In the last paragraph,‖that process‖means ___ A. analyzing species B. creating a new tool C. collecting data D. describing species

Lying in the sun on a rock,the cougar(美洲豹)saw Jeb and his son,Tom before they saw it.Jeb put his bag down quickly and pulled his jacket open with both hands,making himself look big to the cougar,It worked.The cougar hesitated,ready to attack Jeb,but ready to forget the whole thing,too.

Jeb let go of his kacked,grasped Tom and held him across his body,making a cross.Now the cougar’s enemy looked even bigger,and it rose up,ready to move away,but unfortunately Tom got scared and struggled free of Jeb.

―Tom,no‖shouted his father.

But Tom brokd and ran and that’s the last thing you do with a cougar.The second Tom broke free,Jeb threw himself on the cougar,just as it jumped from the rock.They hit each other in mid-air and both fell,The cougar was on Jeb in a flash,fotgeiting about Tomm,which was what Jeb wanted.

Cougars are not as big as most people think and a determined manstands a chance,even with just his fists.As the cougar’s claws(爪子)got into his left shoulder,Jeb swung his fist at its eyes and hit hard.The animal howled(吼叫)and put its head back.Jeb followed up with his other fist.Then out of the corner of his eye.Jeb saw Tom.The boy was running back to help his father.

―Knife,Tom,‖shouted Jeb.

The boy ran to his father’s bag,while Jeb strated shouting as well as hitting,to keep the cougar’s attention away from Tom.Tom got the knife and ran over to Jeb.The cougar was moving its head in and out,trying to find a way through the wall Jeb was making out of his arms.Tom swung with the knife,into the cougar’s back.It howled horribly and ran off into the mountains.

The Best of Friends

The evidence for harmony may not be obvious in some families.But it seems that four out of five young people now get on with their parents,which is the opppsite of the popularly held image(印象)of unhappy teenagers locked in their room after endless family quarrels.

An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.‖We were surprised by just how positive today’s young people seen to be about their families,‖said one member of the research team.‖They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds;they want a car and material goods,and they worry about whether school is serving them well.There’s more negotiation(商议) and discussion between parents and children,and children expect to take part in the family decision-making process.They don’t want to rock the boat.‖

So it seems that this generation of parents is much more likely than parents of 30 years ago to theat their children as friends.‖My parents are happy to discuss things with me and willing to listen to me,‖says 17-years-old Daniel Lazall.‖I always tell them when L’m going out clubbing.As long as they know what I’m doing,they’re fine with it.‖Susan Crome,who is now 21,agrees.‖Looking back on the last 10 years,there was a lot of what you could call negotiation.For example,as long as I’d done all my homework,I could go out on a Saturday night.But I think my grandparents were a lot stricter with my parents than that.‖

Maybe this positive view of family life shoululd not be unexpected.It is possible that the idea of teenages rebellion is not rooted in real facts.A researcher comments,‖Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings.But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.The normal situation throughout history has been a smooth change fromm helping out with the family business to taking it over.‖

67.What is the popular images of teenagers today? A. They worry about school

B. They dislike living with their parents

C. They have to be locked in to avoid troubles D. They quarrel a lot with other family members 68.The study shows that teenagers don’t want to ___

4

69.Compared with parents of 30 years age,today’s parents___. A. go to clubs more often with their children B. are much stricter with their children C. care less about their children’s life D. give their children moren freedom

70.According to the authour,teenage rebellion____. A. may be a false belief B. is common nowadays C. existed only in the 1960s

D. resulted from changes in families 71.What is the passage mainly about? A. Negotiation in family B. Education in family C. Harmony in family

D. Teenage trouble in family

E Hunting

The days of the hunter are almost over in India.This is partly because there is practically nothing left to kill,and partly because some steps have been taken,mainly by banning tiger-shooting,to protect those animals which still survive.

Some people say that Man is naturally a hunter.I disagree with this view.Surely out earliest fordfathers,who at forst possessed no weapons,spent their time digging for roots,and were no doubt themselves often hunted by meat-eating animals.

I believe the main reason why the modern hunter kills is that he thinkds people will admie his courage in overpowering dangerous animals.Of course,there are some who truly believe that the killing is not really the important thing,and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countrysidel.There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design;these men go out after dangerous animals like tigers,even if they say they only do it to rid the countryside of a threat.I can respect reasons like these,but they are clearly different from the need to strengthen your high opinion of yourself.

The greatest big-game hunters expressed in their writings something of these finer motives(动机).One of them wrote.

―You must properly respect what you are after and shoot it cleanly and on the animal’s own territory(领地)。You must fix forever in your mind all the wonders of that particular day.This is better

than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten,half alive,by other animals,Hunting is not a cruel and senseless killing – not if you respect the thing you kill,not if you kill to eich your memories,not if you kill to feed your people.‖

I can understand such beliefs,and can compare these hunters with those who hunted lions with spears(矛) and bravely caught them by the tail.But this is very different from many tiger—shoots I have seen,in which modern weapons were used.The so—called hunters fired from tall trees or from the backs of trained elephants.Such methods made tigers seem no more dangerous than rabbits. 72.Theere is no more hunting in India now partly because___. A.it is dangerous to hunt there B.hunting is already out of date C.hunters want to protect animals D.there are few animals left to hunt

73.The author thinks modern hunters kill mainly____. A.to make the countryside safe B.to earn people’s admiration C.to gain power and influence D.to improve their health

74.What do we learn about the big-game hunters? A.They hunt old animals B.They mistreat animals C.They hunt for food D.They hunt for money

75.What is the author’s view on the tiger-shoots he has seen? A.Modern hunters lack the courage to hunt face-to-face B.Modern hunters should use more advanced weapons C.Modern hunters like to hunt rabbits instead of tigers D.Modern hunters should put their safety first
