Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of travel in the foreseeable future.
The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.
Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One proposed solution to this problem is the automated highway system.
When the auto enters the highway system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached
A. A rail.
B. An engine.
C. A retractable arm.
D. A computer controller.

Less Is More
It sounds all wrong一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 focusing on one weak spot.The discovery should lead to more effective and
lighter packaging materials.
Carpenters have known_________(1)centuries that some woods are tougher than
others. Hickory (山核桃木）,for example, was turned into axe handles and cartwheel
spokes（轮辐）because it can absorb shocks without breaking.White oak,for example,
is much more easily damaged,_________(2)it is almost as dense.Julian Vincent at
Bathe University and his team were convinced the wood's internal structure could explain the
differences.
Many trees have tubular（管的）vessels that run_________(3) the trunk and carry
water to the leaves.In oak they are large,and arranged in narrow bands,but in hickory
they are smaller, and more evenly distributed.The researchers_______(4)this
layout might distribute a blow's energy throughout the wood,soaking up a bigger hit.To
test the idea , they drilled holes 0._________(0.) 65 millimetres across into a block of spruce（云杉）,a
wood with_________(5)vessels,and found that________(6)with stood a harder
knock.__________(7)when there were more than about 30 holes per square centimetre
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_________(8).All the energy from the blow goes towards breaking
the material in one or two places,but often the pieces left_________(9)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_________(10)the wood breaks,and it can then absorb more__________(11),
more safely."
The researchers believe the principle could be applied to any material一______(12)
example,to manufacture lighter and more protective packaging.It could__________(13)
be used in car bumpers,crash barriers and armour for military vehicles,says Ulrike
Wegst,_________(14)the Max Plank Institute for Mental Research in Stuttgart.But she
emphasizes that you________(15)to design the substance with the direction of force in
