How you end a computer session depends on how you use the computer, your views on energy conservation(能源的節(jié)約), and what you have been told about how your decision will affect your investment’s longevity: will frequent starting and stopping cause its circuits(電路) to burn out sooner?
Rest easy, your computer is more likely to be damaged by a virus picked up from the Internet than by being turned off and on too much.They are also energy-efficient: such efficiency has reached the point where most computers place themselves in sleep mode if they remain idle(閑置的) for a certain period of time.So your computer will likely slip into sleep mode anyway, even if you leave it on overnight.
Sleep mode itself, once a pretty unreliable option—you never knew if you would be able to wake your computer without having to reboot (重新啟動(dòng)) it—has been vastly improved with newer operating systems.If you want your computer to consume as little energy as possible when not in use, shut it down.If you want it to consume zero energy, you’re going to have to unplug (拔去……的電源插頭) it.
Your computer can be in only three states: on, sleep or off—each of which draws some level of electric current. A computer that is “on” will either be actively processing
information or sitting idle, depending on whether the user is typing a document, reading an e-mail or has stepped away briefly.The amount of wattage (瓦特?cái)?shù)) drawn when the computer is on varies greatly depending on whether it is a laptop or a desktop computer.The latter uses more energy because desktop power supplies are less efficient and require a separate and often larger, power-hungry monitor. It also varies based on the type of work being done: complex calculations requiring intensive processing are more power-hungry, whereas writing or Web browsing consumes far less electricity.

When top engineers in Germany wanted to build a more energy-efficient car, they headed to the natural history museum to study dolphins and sharks.But it was the boxfish (盒子魚(yú))that interested them.
“We were surprised when this clumsy-looking fish became our model for designing an aerodynamic(空氣動(dòng)力學(xué)的)car,”says Thomas Weber.He is the research and development chief for the car company Daimler.An aerodynamic design reduces wind drag and increases fuel efficiency.
The boxfish may look clumsy, but it can start, stop, back up and zigzag(曲折前進(jìn)) through the water with ease.And it does all this using surprisingly little energy.Daimler’s bionic(仿生學(xué)的) car is modeled on the fish’s boxy skeletal(骨骼的) system.Like the fish, the car is fast and drives easily.It’s efficient too.
The science behind nature-inspired inventions is called biomimicry(生物仿生).Biologist Janine Benyus came up with the term.As co-founder of the Biomimicry Guild, she has worked with cereal companies,sneaker designers and others to develop products based on Nature’s best ideas.
For scientists and inventors, the possibilities for copying nature are limitless.Technology may never be as efficient as nature, or as colorful.But that doesn’t mean we should stop trying to learn from the world around us.Take a walk outside.Watch a squirrel climb up a tree.Look closely at the veins(紋理) of a leaf.Hear the birds chirping in the trees.Such small details may help solve big problems in the future.
()1.Which is TRUE according to the passage?
A.In America a self-cleaning paint was modeled on the lotus flower.
B.Zimbabwe engineers learned from termites to create highly advanced heating systems.
C.After the boxfish, many other ideas of new products are borrowed from nature.
D.Nature is a good source to turn to for improving technology.
()2.The clumsy-looking boxfish interested the scientists because of the following reasons EXCEPT that________.
A.it swims using little energy
B.being boxy, it looks quite like a car
C.some engineers had researched on how to swim easily in the water

()3.Why did top engineers in Germany go to the natural history museum?
A.They wanted to pay a visit to the animals there because they were so lovely.
B.They wanted to carry out a research of boxfish and dolphins.
C.They wanted to search for a model to base on for building a more-efficient car.
D.They wanted to study the science of survival.
()4.We can infer from the passage EXCEPT ________.
A.it is believed that the creation of the airplane might have originated from the bird flying in the sky
B.the atmosphere on the earth cannot be transferred into the original idea
C.dolphins and sharks may become the source of scientists, inventions or creations

A.How Daimler’s bionic car came into being.
B.Nature has inspired a lot of inventions and will continue to.
C.Scientists and inventors’ contribution to modern industry comes from nature.
D.The Nature’s 100 best list.

If cars had wings,they could fly and that just might happen, beginning in 2011.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car-plane, the Transition, to customers by the end of 2011.
“It’s the next ‘wow’ vehicle,”said Terrafugia vice president Richard Gersh.“Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car-plane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving.A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies, although it is both.The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go.When you land, you fold up the wings and hit the road.There are no expensive parking fees because you don’t have to store it at an airport—you park it in the garage at home.
The car-plane is designed to fly primarily under 10,000 feet.It has a maximum take-off weight of 1,430 pounds, including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(臨界)conditions.
The Transition’s price tag: $194,000, But there may be additional charges for options like a radio, transponder or GPS.Another option is a full-plane parachute.
“If you get into a very awful situation, it is the necessary safety option,” Gersh said.
So far, the company has more than 70 orders with deposits.“We’re working very closely with them, but there are still some remaining steps,” Brown said.
()1.We can learn from the first paragraph that ________.
A.car-planes will be popular in 2011
B.people might drive a car-plane in 2011
C.both Transition and Ferrari can take off and land
D.Richard Gersh is the vice president of Massachusetts
()2.It takes the car-plane one minute to ________.
A.fold and unfold its wings
B.unfold wings for flying
C.land in the airport
D.meet flying safety regulations
()3.According to the passage, which of the following is NOT true?
A.The car-plane needs a runway to take off and land.
B.To meet aircraft regulations, the company has been working with FAA.
C.The car-plane may fly as high as normal planes.
D.People can park the car-plane in the garage at their home.
()4.The underlined word “it” in the last but one paragraph refers to ________.
A.the radio
B.the transponder
C.the GPS
D.the full-plane parachute
()5.What’s the best title for the passage?
A.Cars With Wings May Be Just Around the Corner
B.Which to Choose: A Ferrari or a Car Plane?
C.A More Convenient and Cheaper Way to Fly
D.Cars With Wings Can Fly as Fast as Planes
