The Forbidden Apple
New York used to be the city that never sleeps. These days it's the city that never smokes,drinks or does anything naughty(at least,not in public).The Big Apple is quickly turning into the Forbidden Apple.
If you wanted a glass of wine with your picnic in Central Park,could you have one?No chance. Drinking alcohol in public isn't allowed. If you decided to feed the birds with the last crumbs（碎屑）of your sandwich, you could be arrested. It's illegal. If you went to a bar for a drink and a cigarette,that would be OK,wouldn't it?Er…no.You can't smoke in public in New York City.
What's going on?Why is the city that used to be so open-minded becoming like this?
The mayor of New York is behind it all. He has brought in a whole lot of new laws to stop citizens from doing what they want,when they want.
The press are shocked. Even the New York police have joined the argument. They re- cently spent$100,000 ona“Don't blame the cop”campaign. One New York police officer said,”We raise money for the city by giving people fines for breaking some very stupid laws. It's all about money.”
The result is lot of fines for minor offences. Yoav Kashida,and Israeli tourist,fell asleep on the subway. When he woke up,two police officers fined him because he had fallen asleep on two seats(you mustn't use two seats in the subway).Elle and Serge Schroitman were fined for blocking a driveway with their car. It was their own driveway.
The angry editor of Vanity Fair magazine,Graydon Carter,says.”Under New York City law it is acceptable to keep a gun in your place of work,but not an empty ashtray.”He should know. The police came to his office and took away his ashtray（烟灰缸）.
But not all of New York's inhabitants are complaining. Marcia Dugarry,72,said,”The city has changed for the better. If more cities had these laws,America would be a better place to live.”Nixon Patotkis,38,a barman,said,”I like the new laws. If people smoked in here, we'd go home smelling of cigarettes.”
Recent figures show that New York now has fewer crimes per 100,000 people than 193 other US cities.And it's true一It's safer,cleaner and more healthy than before. But let'sbe honest一who goes to New York for its clean streets?
The businessman like the new laws.
A: Right
B: Wrong
C: Not mentioned

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.

_____(4)She entered a bullfighting school in Malaga at age nine and performed her

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

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-

whales are air-breathed)and tolerating the great change in pressure.Just how he does it scientists have nol

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.
