ting department gave a nod to the product"s troubled history．"Finally．" read the big headline Thursday above a picture of the white phone on the homepage of Apple．com．
The white model was supposed to ship alongside the black one at the iPhone 4"s launch（推出） last June．But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say．
As CNN reported last month, earlier
test models of the white iPhone 4 produced unclear photos, especially when the flash（闪光灯） was used．Its whiteness confused the proximity sensor （距离传感器） , which detects when the phone is held next to someone"s head and turns off the touch screen to save battery life．These problems weren"t present in older iPhones that came in white because they didn"t have flash photography; the proximity sensor was unaffected because the front side of previous models was black．
"We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren"t," Philip Schiller, Apple"s chief marketing executive, said in an interview．"It"s not as simple as making something white．There"s a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors．"
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple"s phones．He says Apple could sell 1 million to 1．5 million every three months until the next iPhone model is unveiled, which is expected to be this fall．
Forty-five people were lined up at Apple"s flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report．

| A．it"s always sold out due to its popularity |

| A．There are multi-colored models of iPhone 4． |

Education is 24 , compared with schooling. Education has no 25 . It can take place 26 , whether in the shower or on the bus, whether in a kitchen or on a tractor. It includes both the 27 learning that takes place in schools and the whole universe of learning out of class.
28 the experience of schooling can be known in advance, education quite often produces 29 . A chance talk with a 30 may lead to a person to discover how 31 he knows of another country. People obtain education from 32 on. Education, 33 ,is a very 34 and unlimited term. It is lifelong experience that starts long 35 the start of school, and one that should be a necessary part of one’s entire life.
Schooling, on the other hand, is a 36 experience, whose style changes 37 from one way to the next. Throughout a country, children arrive at school at the same time, take 38 seats, use similar textbooks, do homework ,and 39 ,and so on. Schooling has usually been 40 by the edges of the subjects being taught.

There are more than one billion people in the world who live without 37 drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39 challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41 of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43 in old batteries harm the water of Lake Erie.
Haggerty learnt that 44 the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47 her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With the help from her family, friends and local waste-management 49 , she gathered containers, arranged transportation, and made a(n) 50 video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite __53 . “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize is 54 to young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.

Another exception is that very odd liquid, water, which has many strange properties (特性). As water gets colder it contracts (收缩), which is ordinary behavior, until it reaches the temperature of 30℃. above freezing point. After that, as it gets colder, it expands. This is fortunate---for considering the freezing of a pond. As the water on top gets colder, it shrinks; and so, volume for volume, it becomes heavier and sinks. This goes on until all the pond is at 30℃, but after that, as the water becomes colder it expands. Therefore the colder water stays on top and freezes, covering the pond with ice. If the water went on contracting down to the freezing point, the pond would become a solid block of ice in the end. This would not worry people who live in hot climates, but it would be very serious for those who live in cold climates, especially for those who want to break the ice and catch fish which live in the cold water beneath.

Among the fully electric vehicles on display were the Ford Focus Electric and the Honda Fit EV. BMW and Volvo also had prominent displays at the show, proving that they can produce practical, yet spacious family-oriented electric cars.
Industry insiders at the show claimed that more efficient batteries, improved performance and greater consumer acceptance could make 2011 the “year of el
ectric car”.It’s long been clear that electric cars score heavily for convenience. They are, for instance, much easier to maintain than gasoline-powered cars. When the battery runs out, you simply replace it or recharge it, just like you would for a cell phone or a laptop.
This is also a much cheaper method than filling your tank with gasoline. Better yet, electric cars don’t emit exhaust fumes. As a result, they don’t produce environmentally damaging greenhouse gases.
It appears that improved technology is making electric cars and their maintenance much more user-friendly. So, what are the obstacles which are preventing electric cars from becoming popular and fashionable?
Home charging for electric cars could be extremely convenient for users. However, it is also a potential obstacle. For a start, installing charging stations in owners’ homes will be a challenge, particularly for those who have to park several blocks away from their homes.
Also, charging the car’s battery still takes quite a long time. It may be some time yet before you can recharge an electric car in the same time as you can refill your gas tank.
Another problem is that many electric vehicles have limited ranges that may only allow for journeys of 50 miles (80 km) or less between charges. In cases where a driver wishes to charge the car primarily at home (perhaps overnight), this limits their daily driving to the range of their vehicle.
This may be one reason why hybrid cars are now becoming more popular. A hybrid car has more than one energy source, usually a traditional gasoline fuel tank and an electric battery. It’s like a more practical version of an electric car: It’s greener than a conventional vehicle, with fewer CO2 emissions, yet it also doubles as a conventional vehicle.
“I would say that hybrid is a transition to fully electronic,” Road and Track magazine editor Richard Horman told Detroit News during the show. “The trend is for lighter, smarter, more economical cars. Of course
, electronic vehicles are meant to be that way.”This sounds promising, particularly in light of the fact that the show featured more electric cars from big manufacturers than ever before.
However, it seems that the technology associated with electric cars is not yet able to fully meet people’s expectations. Don’t expect gasoline-powered cars to disappear from roads just yet.
小题1: What made electric cars more convenient?
| A．Easier maintenance. | B．High scores on the show. |
| C．Practicality and large space. | D．Much lower prices. |
| A．It is rough work to install charging stations at home. |
| B．It is time-consuming to charge the batteries. |
| C．The ranges between charges are limited. |
| D．There’s no need to fill the tank with petrol. |
| A．gasoline | B．electric | C．combined | D．separated |
| A．introduce the 2011 Auto Show in US | B．get readers informed of electric cars |
| C．comment on different types of cars | D．advertise for electric cars |
