On the day Apple debuted the often-delayed white-colored iPhone 4, the company’s marketing 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.

The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.
A multitude(多数；大批) of factors, both inherited and environmental, influence the development of health related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Grapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical(统计数字的) probability of shortening life is similar to attempting suicide(自杀). Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality(活力；生命力) and longevity(长寿).The concept of personal choice concerning health is important because ____.
| A．personal health choice help cure most illness |
| B．it helps raise the level of our medical knowledge |
| C．it is essential to personal freedom in American society |
| D．wrong decisions could lead to poor health |
To “live a completely sedentary life style”（L7, Para.1）in the passage means____.
| A．to“live an inactive life” |
| B．to “live a proper life” |
| C．to“live a life with complete freedom” |
| D．to “live a life of evil” |
Sound personal health choice is often difficult to make because ____.
| A．current medical knowledge is still insufficient |
| B．there are many factors influencing our decisions |
| C．few people are willing to trade the quality of life for the quantity of life |
| D．people are usually influenced by the behavior of their friends |
To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to ____.
| A．improving the quality of one’s life |
| B．limiting one’s personal health choice |
| C．deliberately ending one’s life |
| D．breaking the rules of social behavior |
According to Fries and Crapo sound health choices should be based on ____.
| A．personal decisions | B．society’s laws |
| C．statistical evidence | D．friend’s opinions |

One of Britain's bravest women told yesterday how she helped to catch suspected （可疑的） police killer David Bieber -- and was thanked with flowers by the police. It was also said that she could be in line for a share of up to ￡30,000 reward money.
Vicki Brown, 30, played a very important role in ending the nationwide manhunt. Vicki, who has worked at the Royal Hotel for four years, told of her terrible experience when she had to steal into Bieber's bedroom and to watch him secretly. Then she waited alone for three hours while armed police prepared to storm the building.
She said: "I was very nervous. But when I opened the hotel door and saw 20 armed policemen lined up in the car park I was so glad they were there.”
The alarm had been raised because Vicki became suspicious （怀疑） of the guest who checked in at 3 pm the day before New Year's Eve with little luggage and wearing sunglasses and a hat pulled down over his face. She said: "He didn't seem to want to talk too much and make any eye contact （接触）." Vicki, the only employee on duty, called her bosses Margaret, 64, and husband Stan McKale, 65, who phoned the police at 11 pm.
Officers from Northumbria Police called Vicki at the hotel in Dunston, Gateshead, at about 11:30 pm to make sure that this was the wanted man. Then they kept in touch by phoning Vicki every 15 minutes.
"It was about ten past two in the morning when the phone went again and a policeman said ‘Would you go and make yourself known to the armed officers outside?'. My heart missed a beat."
Vicki quietly showed eight armed officers through passages and staircases to the top floor room and handed over the key.
"I realized that my bedroom window overlooks that part of the hotel, so I went to watch. I could not see into the man's room, but I could see the passage. The police kept shouting at the man to come out with his hands showing.

Washington, D.C. is home to famous buildings, memorials and museums that visitors love. But it is also home to a large and beautiful green space. There are many arboretums in the city. Today, we take you to the United States National Arboretum, an active center for both scientific research and public education.
Many people who come to Washington are astonished when they first visit the National Arboretum. The Arboretum is only a short drive from the center of the city. However, visitors often feel like they are remote from the busy American capital. The Arboretum covers one hundred eighty hectares of green space in the northeast part of Washington. The area is famous for its beautiful flowers, tall trees and other plants. About nine thousand different kinds of plants grow there.
The National Arboretum was established by an act of Congress in 1927. Today, the United States Department of Agriculture’s Agricultural Research Service operates the Arboretum.
The goal of the Arboretum is to carry out studies and provide education in an effort to improve the environment. The goal includes protecting trees, flowers and other plants and showing them to the public. The National Arboretum is a popular stop for visitors to Washington. It is open every day of the year except December twenty-fifth, the Christmas holiday. Money is not necessary to visit the Arboretum.
As many as six hundred thousand people visit the Arboretum’s grounds each year. Hundreds of thousands of people also visit with the help of computers. They use the Arboretum’s Internet web site to learn about current research programmes and how to care for plants. Director Thomas Elias says Arboretum officials would like to see even more visitors. He says they believe that many people do not know it exists. Part of the problem might result from the fact that the Arboretum is about five kilometers from the closest train station. Many famous places in Washington are a short walk from Metrorail, the local train system.
The Arboretum is easy to reach by automobile or bus, however. About fifteen kilometers of roads have been built on the property. The roads connect to major collections and seasonal flowers. The Arboretum also welcomes people on bicycles. Disabled persons or those who want to walk only short distances may visit four beautiful areas that are close to each other.The underlined word “arboretums” in Paragraph 1 means______.
