Memories of highly charged events, like the London bombings of the 7th July 2005, can be inaccurate and should not be relied on in court, according to a study in Britain. People can create false memories, bringing problems for police investigations.

The simultaneous (同时) bombings of three underground trains and a double－decker bus in London some years ago are imprinted on the minds of many people in Britain.

But our memories of the attacks are unreliable, according to a study from Portsmouth University. Forty percent of British students questioned about the events remembered seeing a film recorded by a CCTV(闭路监控) camera that shows a particular event of the bus bomb——footage(片段) which never existed. A further 28% claimed to have seen a non－existent computerized reconstruction.

Some even recalled specific details of the attack, which none of them witnessed. "The bus had just stopped to let people off when two women and a man got on," said one. "He placed a hag by his side, the woman sat down and as the bus left, there was an explosion. There was a leg on the floor." Another described how the bus had stepped at a traffic light when there was a bright light, an explosion and the roof of the bus was blown off by the power of the explosion.

"Memories are not like videotape you can return to the beginning and replay for perfect recall," said lead researcher James Ost. "Because of this, they are not reliable enough to form the basis of legal decisions." He believes people who are more creative might be more inclined to make these kinds of errors.

60．According to the passage, when people are strongly affected by an event______.

A．all they say about the event is not true

B．they couldn't remember anything

C．they couldn't go on the court to be witnesses

D．they couldn't make any errors on what they see about the event

61．The third paragraph______.

A．tells us what some people saw about the attack

B．shows that some people did create some false memories

C．shows that the London bombing was indeed a terrorist attack

D．shows that some people could remember details of an event

62．The underlined word "inclined" in the last paragraph is closest to the meaning of______.

A．careful B．likely C．serious D．curious

63．What is mainly discussed in the passage?

A．How our memories work. B．False memories.

C．How to avoid false memories. D．What can be done to memories.

New technology that can “ see ” through clothing and detect what ’ s underneath can now be used to scan crowds, making it a potentially effective tool to prevent terrorist attacks in public places.

The Thru Vision T5000 camera picks up Terahertz rays ，or T-rays, which are naturally sent out by all objects and can pass through clothes or even walls. The camera can then detect metallic and nonmetallic objects hidden under clothing on still or moving subjects without showing any body detail.

While similar technology is seen at airports around the world, the T5000 is designed to be used in large, open areas. With a range of 25 meters, the T5000 can screen people in public places, thus avoiding bottle-necks at border crossing or security checkpoints. It also means people can be screened without knowing it.

The technology develops from British astronomers ’ work in studying dying stars. Astronomers use T-ray cameras to see through dust and clouds in space. The company sees uses for its camera at other sites where political or business activities take place.

For privacy concerns，Thru Vision Chief Executive Clive Beattie said the image produced by the camera did not show detailed parts of the body. ” It's almost a shining light bulb(灯泡）.“ Beattie said. "You don' t see the detail that people might be concerned about. “ In London' s busy Piccadilly Circus—which is already filled with closed -circuit surveillance (监视）cameras— reaction to the new technology was mixed. Some said the camera was going too far and violating privacy，but others said they are willing to put safety before privacy concerns. “ There ’ s surveillance everywhere anyway, “ said one commuter. “I don' t think it’ s much of a difference. I don' t care that they can see through me because they can see me anyway.“

Some experts said the privacy violation of the camera was not worth the benefit. “ What we should consider is how much we want to lose our privacy in order to obtain a sort of national security，” said David Murakami Wood，director of the Surveillance Studies network，which deals with surveillance and privacy problems. “ In most cases this isn' t real security—it ’ s a sense of safety that has very little real effect. ”

Federal regulators (管理者) Wednesday approved a plan to create a nationwide emergence alert (警报) system using text messages delivered to cell phones.

Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates（估计） more than 48 billion text messages are sent each month.

The plan comes from the Warning Alert and Response Network Act, a 2009 federal law that requires improvements to the nation's emergency alert system. The act tasked(派给…工作) the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.

"The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan.

Participation in the alert system by carriers –telecommunications companies is voluntary, but it has received solid support from the wireless industry.

The program would be optional for cell phone users. They also may not be charged for receiving alerts.

There would be three different types of messages, according to the rules.

The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction (绑架) emergencies, or so-called Amber Alerts.

The service could be in place by 2012.

1.What is the purpose of the approved plan?

A. To warn people of emergencies through messages.

B. To popularize the use of cell phones.

C. To estimate the monthly number of messages.

D. To promote the wireless industry.

2.The improvement to the present system is in the charge of ____.

A. CTIA B. the Warning Alert and Response Network C. FCC D. federal regulators

3.The carriers’ participation in the system is determined by _____.

A. the US federal government B. mobile phone users

C. the carriers themselves D. the law of the United States

4.Which of the following is true of cell phone users?

A. They must accept the alert service. B. They may enjoy the alert service for free.

C. They must send the alerts to others D. They may choose the types of messages
