New Understanding of Natural Silk's Mysteries
Natural silk,as we all know,has a strength that man-made materials have long struggled to match.In a
discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough,MIT re-
searchers have discovered that silk gets its strength from its weakness.Or,more specifically,its many weak-
nesses. Silk gets its extraordinary durability and ductility（柔韧性）from an unusual arrangement of hydrogen
bonds that are intrinsically very weak but that work together to create a strong,flexible structure.
Most materials一especially the ones we engineer for strength一get their toughness from brittleness.As
such,natural silks like those produced by spiders have long fascinated both biologists and engineers because of
their light weight,ductility and high strength(pound for pound,silk is stronger than steel and far less brittle).
But on its face,it doesn't seem that silks should be as strong as they are;molecularly,they are held together by
hydrogen bonds , which are far weaker than the covalent（共价的）bonds found in other molecules.
To get a better understanding of how silk manages to produce such strength through such weak bonds,
the MIT team created a set of computer models that allowed them to observe the way silk behaves at the
atomic level. They found that the arrangement of the tiny silk nanocrystals（纳米晶体）is such that the hydro-
gen bonds are able to work cooperatively,reinforcing one another against external forces and failing slowly
when they do fail,so as not to allow a sudden fracture to spread across a silk structure.
The result is natural silks that can stretch and bend while retaining a high degree of strength.But while
that's all well and good for spiders,bees and the like,this understanding of silk geometry could lead to new
materials that are stronger and more ductile than those we can currently manufacture.Our best and strongest
materials are generally expensive and difficult to produce(requiring high temperature treatments or
energy-intensive processes).
By looking to silk as a model,researchers could potentially devise new manufacturing methods that rely
on inexpensive materials and weak bonds to create less rigid,more forgiving materials that are nonetheless
stronger than anything currently on offer. And if you thought you were going to get out of this materials
science story without hearing about carbon nanotubes（纳米碳管）, think again. The MIT team is already in
the lab looking into ways of synthesizing silk-like structures out of materials that are stronger than natural
silk-like carbon nanotubes. Super-silks are on the horizon.If the hydrogen bonds break due to external forces,they break fast.

第4题：
Years ago,a cigarette commercial asked if you were smoking more,but enjoying it less．That describes the way many of us live today．We are doing more,but enjoying it less．And when that doesn't work,we get the problem．In our extremely hurried search for satisfaction,we try stuffing still more into our days,never realizing that we are taking the wrong approach.
The truth is simple;so simple it is hard to believe．Satisfaction lies with less,not with more．Yet,we pursue the myth that this thing,or that activity,will somehow provide the satisfaction we so desperately seek.
Arthur Lindman,in his very effective book,"The Harried Leisure Class,"described the uselessness of pursuing more．His research focused on what people did with their leisure time．He found that as income rose,people bought more things to occupy their leisure time．But,ironically,the more things they bought,the less they valued any one of them．Carried to an extreme,he predicted massive boredom in the midst of tremendous variety．That was more than twenty years ago,and his prediction seems more accurate every year.
Lindman of course,is not the first to discover this．The writer of Ecclesiastes expressed the same thought thousands of years ago．It is better,he wrote,to have less,but enjoy it more.
If you would like to enjoy life more,I challenge you to experiment with me．How could you simplify your life?What could you drop?What could you do without?What could you stop pursuing?What few things could you concentrate on?
The more I learn,the more I realize that fullness of life does not depend on things．The more I give up,the more I seem to gain．But words will never convince you．You must try it for yourself．
The best title for the passage is__.A.Simplify Your Life
B.Enjoy Your Life
C.Smoking Less

Mr．Hill works in a bank,and lives alone．The only family he has is in the next town:his sister lives there with her husband,and her son,Jack．Mr．Hill does not see his sister,or her family,from one year to the next,but he sends them Christmas cards,and he has not forgotten one of Jack's seventeen birthdays.
Last week Mr．Hill had quite a surprise．He drove home from the bank at the usual time,driving neither too slowly nor too fast;he parked his car where he always parked it,out of the way of other cars,and he went inside to make his evening meal．Just then,there was a knock at the door．He opened the door,to find a policeman standing on the door-step.
"What have I done wrong?"Mr．Hill asked himself．"Have I driven on the wrong side of the road?Has there been some trouble at the bank?Have I forgotten to pay an important bill?"
"Hello,Uncle,"said the policeman,"My name is Jack."

第7题：
Lucky is the man who has no "skeleton in his closet". When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a "skeleton in his closet". Some people may have more than one skeleton.
As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England.
Before 1932, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse (尸体) of an executed (处决) criminal.
But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices.
We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor would keep his skeleton in some dark corner where it could not be seen, or hide it in a closet.
After a time, people began to suspect (怀疑) every doctor of hiding a skeleton in the closet. From this suspicion, the phrase "a skeleton in the closet" took on a broader, more general meaning to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory.
One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man’s guess is as good as another. But this sounds like a story by the great French novelist, Balzac.
Baizac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly hides her lover in the closet of her bedroom. He enters her room and asks her if she is hiding her lover. He says he will not open the door to the closet if she promises him there is no one there; He will believe her. She answers firmly that she is not hiding anyone in the closet.
The husband then begins to build a solid brick wall against the closet. His wife watches, knowing that her lover will never come out alive. But she will not change her story and admit her guilt.In Chinese the world "skeleton" means （）.- A、尸体
- B、标本
- C、收藏
- D、骷髅

New Understanding of Natural Silk's Mysteries
Natural silk,as we all know,has a strength that man-made materials have long struggled to match.In a
discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough,MIT re-
searchers have discovered that silk gets its strength from its weakness.Or,more specifically,its many weak-
nesses. Silk gets its extraordinary durability and ductility（柔韧性）from an unusual arrangement of hydrogen
bonds that are intrinsically very weak but that work together to create a strong,flexible structure.
Most materials一especially the ones we engineer for strength一get their toughness from brittleness.As
such,natural silks like those produced by spiders have long fascinated both biologists and engineers because of
their light weight,ductility and high strength(pound for pound,silk is stronger than steel and far less brittle).
But on its face,it doesn't seem that silks should be as strong as they are;molecularly,they are held together by
hydrogen bonds , which are far weaker than the covalent（共价的）bonds found in other molecules.
To get a better understanding of how silk manages to produce such strength through such weak bonds,
the MIT team created a set of computer models that allowed them to observe the way silk behaves at the
atomic level. They found that the arrangement of the tiny silk nanocrystals（纳米晶体）is such that the hydro-
gen bonds are able to work cooperatively,reinforcing one another against external forces and failing slowly
when they do fail,so as not to allow a sudden fracture to spread across a silk structure.
The result is natural silks that can stretch and bend while retaining a high degree of strength.But while
that's all well and good for spiders,bees and the like,this understanding of silk geometry could lead to new
materials that are stronger and more ductile than those we can currently manufacture.Our best and strongest
materials are generally expensive and difficult to produce(requiring high temperature treatments or
energy-intensive processes).
By looking to silk as a model,researchers could potentially devise new manufacturing methods that rely
on inexpensive materials and weak bonds to create less rigid,more forgiving materials that are nonetheless

science story without hearing about carbon nanotubes（纳米碳管）, think again. The MIT team is already in
the lab looking into ways of synthesizing silk-like structures out of materials that are stronger than natural
silk-like carbon nanotubes. Super-silks are on the horizon.Silk's strength comes from its weak hydrogen bonds working together.

New Understanding of Natural Silk's Mysteries
Natural silk,as we all know,has a strength that man-made materials have long struggled to match.In a
discovery that sounds more like an ancient Chinese proverb than a materials science breakthrough,MIT re-
searchers have discovered that silk gets its strength from its weakness.Or,more specifically,its many weak-
nesses. Silk gets its extraordinary durability and ductility（柔韧性）from an unusual arrangement of hydrogen
bonds that are intrinsically very weak but that work together to create a strong,flexible structure.
Most materials一especially the ones we engineer for strength一get their toughness from brittleness.As
such,natural silks like those produced by spiders have long fascinated both biologists and engineers because of
their light weight,ductility and high strength(pound for pound,silk is stronger than steel and far less brittle).
But on its face,it doesn't seem that silks should be as strong as they are;molecularly,they are held together by
hydrogen bonds , which are far weaker than the covalent（共价的）bonds found in other molecules.
To get a better understanding of how silk manages to produce such strength through such weak bonds,
the MIT team created a set of computer models that allowed them to observe the way silk behaves at the
atomic level. They found that the arrangement of the tiny silk nanocrystals（纳米晶体）is such that the hydro-
gen bonds are able to work cooperatively,reinforcing one another against external forces and failing slowly
when they do fail,so as not to allow a sudden fracture to spread across a silk structure.
The result is natural silks that can stretch and bend while retaining a high degree of strength.But while
that's all well and good for spiders,bees and the like,this understanding of silk geometry could lead to new
materials that are stronger and more ductile than those we can currently manufacture.Our best and strongest
materials are generally expensive and difficult to produce(requiring high temperature treatments or
energy-intensive processes).
By looking to silk as a model,researchers could potentially devise new manufacturing methods that rely
on inexpensive materials and weak bonds to create less rigid,more forgiving materials that are nonetheless
stronger than anything currently on offer. And if you thought you were going to get out of this materials
science story without hearing about carbon nanotubes（纳米碳管）, think again. The MIT team is already in
the lab looking into ways of synthesizing silk-like structures out of materials that are stronger than natural
silk-like carbon nanotubes. Super-silks are on the horizon.The MIT team had tried different materials before they studied natural silk in their research.

第16题：
Years ago,a cigarette commercial asked if you were smoking more,but enjoying it less．That describes the way many of us live today．We are doing more,but enjoying it less．And when that doesn't work,we get the problem．In our extremely hurried search for satisfaction,we try stuffing still more into our days,never realizing that we are taking the wrong approach.
The truth is simple;so simple it is hard to believe．Satisfaction lies with less,not with more．Yet,we pursue the myth that this thing,or that activity,will somehow provide the satisfaction we so desperately seek.
Arthur Lindman,in his very effective book,"The Harried Leisure Class,"described the uselessness of pursuing more．His research focused on what people did with their leisure time．He found that as income rose,people bought more things to occupy their leisure time．But,ironically,the more things they bought,the less they valued any one of them．Carried to an extreme,he predicted massive boredom in the midst of tremendous variety．That was more than twenty years ago,and his prediction seems more accurate every year.
Lindman of course,is not the first to discover this．The writer of Ecclesiastes expressed the same thought thousands of years ago．It is better,he wrote,to have less,but enjoy it more.
If you would like to enjoy life more,I challenge you to experiment with me．How could you simplify your life?What could you drop?What could you do without?What could you stop pursuing?What few things could you concentrate on?
The more I learn,the more I realize that fullness of life does not depend on things．The more I give up,the more I seem to gain．But words will never convince you．You must try it for yourself．
Lindman wrote his book__.A.ten years ago
B.twenty years ago
C.more than twenty years ago
D.thousands of years ago答案：C解析：第三段最后。Arthur Lind man预言，巨大的无聊存在于极度的丰富之中。而这还是20多年前的预言，并且，他的预言越来越准确。选项D是第四段中另一本书的时间。 -

第三篇
Almost Human?
Scientists are racing to build the world's first thinking robot.This is not science fiction:
some say they will have made it by the year 2020.Carol Packer reports.
Machines that walk,speak and feel are no longer science fiction.Kismet is the name
of an android（机器人）which scientists have built at the Massachusetts Institute of
Technology(MIT).Kismet is different from the traditional robot because it can show
human emotions.Its eyes,ears and lips move to show when it feels happy,sad or bored.
Kismet is one of the first of a new generation of androids一robots that look like human
beings一which can imitate human feelings.Cog,another android invented by the MIT,
imitates the action of a mother. However,scientists admit that so far Cog has the mental
ability of a two-year-old.
The optimists（乐观主义者）say that by the year 2020 we will have created humanoids
（机器人）with brains similar to those of an adult human being. These robots will be
designed to look like people to make them more attractive and easier to sell to the public.
What kind of jobs will they do?In the future,robots like Robonaut,a humanoid invented by
NASA,will be doing dangerous jobs,like repairing space stations.They wi}{also be doing
more and more of the household work for us.In Japan,scientists are designing androids
that will entertain us by dancing and playing the piano.
Some people worry about what the future holds:will robots become monsters（怪物）?
Will people themselves become increasingly like robots?Experts predict that more and more
people will be wearing micro-computers,connected to the Internet,in the future.People
will have micro-chips in various parts of their body,which will connect them to a wide variety
of gadgets（小装置）.Perhaps we should not exaggerate（夸大）the importance of
technology,but one wonders whether,in years to come,we will still be falling in love,
and whether we will still feel pain.Who knows?In about 15 years' time from now,robots
A:will become space designers.
B:will look like monsters.
C:will behave like animals.
D:will think like humans.答案：D解析： -
第19题：
Lucky is the man who has no "skeleton in his closet". When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a "skeleton in his closet". Some people may have more than one skeleton.
As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England.
Before 1932, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse (尸体) of an executed (处决) criminal.
But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices.
We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor would keep his skeleton in some dark corner where it could not be seen, or hide it in a closet.
After a time, people began to suspect (怀疑) every doctor of hiding a skeleton in the closet. From this suspicion, the phrase "a skeleton in the closet" took on a broader, more general meaning to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory.
One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man’s guess is as good as another. But this sounds like a story by the great French novelist, Balzac.
Baizac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly hides her lover in the closet of her bedroom. He enters her room and asks her if she is hiding her lover. He says he will not open the door to the closet if she promises him there is no one there; He will believe her. She answers firmly that she is not hiding anyone in the closet.
The husband then begins to build a solid brick wall against the closet. His wife watches, knowing that her lover will never come out alive. But she will not change her story and admit her guilt.From the text we know that there are （） theories about how the phrase "skeleton in the closet" came into being.- A、one
- B、two
- C、three
- D、four
正确答案:B -
