The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology（纳米技术）, which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology（微电子技术）we use, such as the silicon chips of computers.
Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases.
The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this “absence of evidence” is not being taken as “evidence of absence”. In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods.
One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle（颗粒）size that should concern us, but its functionality. Take gold, for example, which is a famously inert (惰性) substance, and valuable because of it. It doesn’t rust or corrode because it doesn’t interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface area of many pea-sized balls with the same weight of the single basketball. The pea-sized balls have a surface area many hundreds, indeed thousands of times bigger than the basketball, and this allows them to interact more easily with the environment. It is this increased interactivity that changes their functionality—and makes them potentially more dangerous to health or the environment.

Alone in the wilderness. Nothing but jungle. A world of shadow with the rays of light falling like blonde hair from the crowns of the giant trees. Jungle in the midday sun. Everything motionless. Not a sound from sky or earth. Complete silence. Only some coconuts falling, at long intervals, very far away. The world reduced to the soft touch of cool grass along my naked back, and a sweet smell of rich soil and vegetation. Stretched out with closed eyes beside my heavy burden of fruit and firewood, I enjoyed the feeling of fresh blood streaming through every part of my body and fresh jungle air filling every corner of my lungs.
Resting motionless, I could see the sun through my closed eyelids, alone in the sky, as lonely as I, and as motionless and silent as everything else. The earth had surely stopped turning and somewhere on this planet there was supposed to be roaring traffic in busy streets. What a crazy, unbelievable thought!
Another coconut fell, to make the world come to a complete standstill. I had to roll over onto my stomach to feel that at least I could move and make noises. Then I found company. A little brown ant was struggling to find its way with a bit of dry straw through the jungle of leaves and grass below my nose. I wondered if I could give the little fellow a lift with its burden, but it showed not the slightest sign of tiredness and struggled on with all six legs, head first or head last, waving its feelers energetically as if the trip had just started. Who ever saw a tired ant? Tiredness, disagreeable tiredness, is restricted to hunted animals, slaves and modern man. It is as great an effort for an office clerk to walk five blocks with a loaded brief-case as it is for a jungle-dweller to cross a valley with a goat on his back. It is as hard to get up and climb or run when you have been seated for years as it is to get up and walk when you have been in bed for months. The body is strange. Spare it, and you get really tired for almost nothing; use it, and almost nothing makes you really tired.
I rose to my feet. I had heard a horse neighing down in the valley. Above me, on the open highland plains, there were wild horses. But down in the valley there was never a horse unless there was a man on it. Somebody was making his way up the valley and my wife was alone.
1.What’s the right order of the following events?
① I heard a horse neighing down in the valley.
② I went to the jungle.
③ I found an ant carrying a bit of dry straw.
④ I lay on the ground to have a break.
⑤ I picked fruits and chopped firewood.

2.How does the author feel about the ant?
A．He admired its attitude toward work.
B．He was amazed at its tireless efforts.
C．He showed sympathy for the little ant.
D．He was content to have it as a companion.
3.It can be inferred from the last paragraph that the author would probably .
A．work harder than before B．talk to the man on the horse
C．make his way home D．stay in the valley
4.We can learn from the passage that the author .
A．enjoyed being alone
B．experienced a world of quietness
C．missed his busy life in the city

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US．
When 40 per cent of Hawaii's US$14 million-a-year papaya （木瓜）industry was destroyed by a virus five years ago, work began on creating genetically engineered（转基因的）trees．
Researchers successfully introduced seeds that were designed to resist the virus．Since then, more and more people have been testing genetically engineered trees．Some researchers put special bacteria into trees to help them grow faster and produce better wood．Others are trying to create trees that can clean polluted soil．Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper．
The Pentagon （五角大楼） even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack．So far, the poplar, eucalyptus （杨树与桉树）, apple and coffee trees are among those being engineered．All this can be done today because we have a better understanding of tree genomes （基因组）．
However, some people fear that the genetically engineered trees will cause dangerous results．They are worried that the new trees will breed with natural species and change the balance of the forest environment．
“It could be destructive,” said Jim Diamond, an environmentalist. “Trees are what is left of our natural environment and home to many endangered species.”
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers．They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled．
1.Which kind of tree is not the ones that scientists are planting in the US?
A．Trees that worms can't hurt．
B．Genetically engineered trees．
C．Trees that can resist wind better．
D．Trees that can protect themselves at a chemical attack．
2.What caused the American scientists to work on special trees?
A．Tree genomes are mapped out so scientists know how to improve trees．
B．Great numbers of trees have been lost due to attacks by viruses．
C．Researchers successfully introduced seeds designed to resist the virus．
D．They think science could give nature a fighting chance against both natural and man-made dangers．
3.Which of the following was probably the first kind of trees being engineered?
A．Papaya． B．Pine． C．Apple． D．Poplar．
4.Why did critics think engineered trees dangerous? Because ________．
A．these trees can destroy the balance of nature
B．everything except trees has been genetically engineered
C．trees are home to many endangered species
D．these trees may affect normal trees
A device that stops drivers from falling asleep at the wheel is about to undergo(接受) testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue（疲劳）.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel(方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
1.How should a driver respond to the sounds from Driver Alert?
A. By sounding a warning.
B. By touching the wristband.
C. By checking the driving time.
D. By pressing the steering wheel.
2.We can learn from the text that the driver needs to stop for a break when his response time is ________
A. about 400 milliseconds B. below 500 milliseconds
C. over 500 milliseconds D. about 4 minutes
3.When the driver gets sleepy while driving, Driver Alert ______.
A. moves more regularly
B. stops working properly
C. opens the window for the driver
D. sounds more frequently and loudly
4.According to the text, Driver Alert ______.
A. aims to reduce tiredness-related accidents
B. has gone through testing at laboratories
C. aims to prevent drivers from sleeping
D. has been on sale for 12 months
