Female Bullfighting
It was a unique,eye-catching sight:an attractive woman in a shiny bullfighter's suit,
sword in hand,facing the sharp horns of a black,500-kilogram beast.
Most people thought the days of female bullfighting were over in Spain._____(1)
The first woman fighter,Cristina Sanchez,quit in 1999 because of male discrimination
（歧视）.But Vega is determined to break into what could be Spain's most resistant male
field._____(2)
Spanish women have conquered almost all male professions.______(3) "The
bull does not ask for your identity card,"she said in an interview a few years ago.She
insisted that she be judged for her skills rather than her femaleness.
Vega became a matador（斗牛士）in 1 997 in the southwestern city of Caceres.
_____(4)She entered a bullfighting school in Malaga at age nine and performed her
first major bullfight at age 14 .She has faced as much opposition as Sanchez did.And the
"difficulties have made her grow into a very strong bullfighter,"her brother Jorge says.
The 1 .68-metre tall and somewhat shy Vega says her love of bullfighting does not make
her any less of a woman._____(5)
__________（1）
A:.She intends to become even better than Sanchez was.
B:.Her father was an aspiring（有雄心壮志的）bullfighter.
C:.But many bullfighting professionals continue to insist that women do not have what it takes to perform the country's"national show".
D:."I'm a woman from head to toe and proud of it,"she once said.
E:.She looks like a male bullfighter.
F:But recently,29-year-old Mani Paz Vega became the second woman in Spanish history to fight against those heavy animals.

The Greatest Mystery of Whales
The whale is a warm一blooded,air-breathing animal,giving birth to its young alive,sucking them一and,
like all mammals,originated on land. There are many________________(51)of this. Its front flippers（鳍状肢）,
used for steering and stability,are traces of feet.
Immense strength is________________(52)into the great body of the big whales,and in fact most of a
whale's body is one gigantic muscle.The blue whale's pulling strength has been estimated________________(53)
400 horsepower. One specimen was reported to have towed（拖）a whaling vessel for seven hours at the
_______________ (54)of eight knot（节）.
An angry whale will________________(55).A famous example of this was the fate of Whaler Essex,
________________(56)was sunk off the coast of South America early in the last century. More recently,steel ships
have ___________( 57 ) their plates buckled（使弯曲）in the same way. Sperm whales（抹香鲸）were known
to seize the old-time whaleboats in their jaws and crush them.
The greatest________________(58)of whales is their diving ability.The sperm whale dives to the bottom foi
his________________(59)food,the octopus（章鱼）.In that search he is known to go as far down as 3 , 200 feet,
where the________________(60)is 1,400 pounds,to a square inch.Doing so he will________________(61)underwa-
ter as long as one hour. Two special skills are involved in this storing up enough________________(62)(all
whales are air-breathed)and tolerating the great change in pressure.Just how he does it scientists have nol
_______________ (63).It is believed that some of the oxygen is stored in a special________________(64)of blood
vessels,rather than just held in the lungs.And it is believed that a special kind of oil in his head is some sort
of a compensating mechanism that________________(65)adjusts the internal pressure of his body.But since you
can't bring a live whale into the laboratory for study,no one knows just how these things work.
_________(62)
A:heat
B:energy
C:food

Why would They Falsely Confess?
Why on earth would an innocent person falsely confess to committing a crime?To most people,it just doesn't seem logical. But it is logical,say experts,if you understand what can happen in a police interrogation（审讯）room.
Under the right conditions,people's minds are susceptible（易受影响的）to influence , and the pressure put on suspects during police grillings（盘问）is enormous. ________ (1)“The pressure is important to understand,because otherwise it's impossible to understand why someone would say he did something he didn't do. The answer is:to put an end to an uncom-fortable situation that will continue until he does confess.”
Developmental psychologist Allison Redlich recently conducted a laboratory study to de- termine how likely people are to confess to things they didn't do.______(2)The research-ers then intentionally crashed the computers and accused the participants of hitting the“alt” key to see if they would sign a statement falsely taking responsibility.
Redlich's findings clearly demonstrate how easy it can be to get people to falsely con- fess:59% percent of the young adults in the experiment immediately confessed. ______(3) of the 15-to 16-year-olds,72 percent signed confessions,as did 78 percent of the 12-to 13- year-olds.
“There's no question that young people are more at risk,”says Saul Kassin,Professor at Williams College,who has done similar studies with similar results.______(4)
Both Kassin and Redlich note that the entire“interrogation” in their experiments consis-ted of a simple accusation一not hours of aggressive questioning一and still,most participants falsely confessed.
Because of the stress of a police interrogation,they conclude,suspects can become con- vinced that falsely confessing is the easiest way out of a bad situation. ______(5)
_______(4)
A: In her experiment,participants were seated at computers and told not to hit the“alt” key,because doing so would crash the systems.
B:“In some ways,”says Kassin,“false confession becomes a rational decision.”
C: “It's a little like somebody's working on them with a dental（牙的）drill , ” says Frank- lin Zimring,a law professor at the University of California at Berkeley.
D:“But adults are highly vulnerable too.”
E: How could an innocent person admit to doing something he didn't do?
F: Redlich also found that the younger the participant,the more likely a false confession.

Less Is More
It sounds all wrong—drilling holes in a piece of wood to make it more resistant to knocks. But it works because the energy from the blow gets distributed throughout the wood rather than fo-
cusing on one weak spot. The discovery should lead to more effective and lighter packaging mate-rials.
Carpenters have known______(51)centuries that some woods are tougher than others. Hickory,for example,was turned into axe handles and cartwheel spokes because it can absorb shocks without breaking. White oak,for example,is much more easily damaued,________(52)it is almostas dense.Julian Vincent at Bathe University and his team were convinced the wood's internal structure could explain the differences.
Many trees have tubular vessels that run_______(53)the trunk and carry water to the leav- es .In oak they are large,and arranged in narrow bands,but in hickory they are smaller,and more evenly distributed.The researchers________(54)this layout might distribute a blow's en-ergy throughout the wood, soaking up a bigger hit.To test the idea,they drilled holes 0.65 millimetres across into a block of spruce,a wood with_______(55)vessels,and found that_______(56)withstood a harder knock_______（57)when there were more than about 30 holes per square centimeter did the wood's performance drop off.
A uniform substance doesn't cope well with knocks because only a small proportion of the material is actually______( 58).All the energy from the blow goes towards breaking the material in one or two places , but often the pieces left _________( 59 ) are pristine（未经破坏的）.
But instead of the energy being concentrated in one place,the holes provide many weak spots that all absorb energy as they break,says Vincent.“You are controlling the places______(60) the wood breaks,and it can then absorb more______(61),more safely.”
The researchers believe the principle could be applied to any material—_________(62)example,to manufacture lighter and more protective packaging.It could_______(63)be used in car bumpers,crash barriers and armor for military vehicles,says Ulrike Wegst,_______(64) the Max Plank Institute for Mental Research in Stuttgart. But she emphasizes that you'd ________(65)to design the substance with the direction of force in mind.“The direction of loading is crucial,”she says.
