A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami（海啸） warnings just three minutes later. The country has one of the best earthquake early warning systems in the world.

There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes.

There are also concrete(混凝土) sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami.

Costas Synolakis ，a tsunami expert at the University of Southern California in Los Angeles said，"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event."

He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan.

The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas.

Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves.

Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.

Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤)．They said that they found faults in studies that had reported associations between sunscreen use and higher risk of melanoma.

Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.

But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.

The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen．As a result, it may appear that sunscreen users get cancer more often.

The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

People with fair skin and freckles          .

       A．seldom use sunscreen             

       B．are more in danger of skin cancer

       C．can be free from the harm of the sun  

       D．often expose themselves to the sun

We can learn from the passage that          .

       A．sunscreen users get skin cancer more often

       B．the volunteers have proved the effect of sunscreen

       C．the new study was based on the experiences of volunteers

       D．the number of skin cancer patients is increasing in America

Which of the following can be the best title for this passage?

       A．Sunscreen to Prevent Skin Cancer   

       B．Sunscreen to Increase Skin Cancer

       C．Skin Cancer Caused by Sunscreen

A person named Bernard Jackson today is a free man, but he has many bitter memories. He spent five years in prison after a jury (陪审团) wrongly convicted (判处……有罪) him of raping two women. At Jackson’s trial, although two witnesses testified that Jackson was with them in another location at the time of the crime, he was convicted anyway. Why? The jury believed the testimony (证词) of the two victims, who positively identified Jackson as the man who had attacked them. The court eventually freed Jackson after the police found the real criminal.

Many factors influence the accuracy of eyewitness testimony. For instance, witnesses sometimes see photographs of several suspects before they try to identify the person they saw in a group of people. They can become confused by seeing many photographs of similar faces. The number of people in the group, and whether it is a person or a photograph, my also affect a witness’s decision. People sometimes have difficulty identifying people of other races. The questions the police ask witnesses also have an effect on them.

Many people believe that police officers are more reliable than ordinary people. Psychologists decided to test this idea, and they discovered that it is not true. Two psychologists showed a film of crimes to both police officers and civilians. The psychologists found no difference between the police and the civilians in correctly remembering the details of the crimes.

Despite all the possibilities for inaccuracy, courts cannot omit eyewitness testimony from a trial. American courts depend almost completely on eyewitness testimony to resolve (决定) court cases. Sometimes it is the only evidence to a crime, such as rape. Furthermore, eyewitness testimony is often correct. Although people do sometimes make mistakes, and convict innocent people, more importantly, eyewitness testimony has rightly convicted a larger number of guilty people.

American courts depend on the ability of the twelve jurors, and not the judges, to determine the accuracy of the witness’s testimony. It is their responsibility to decide if a certain witness could actually see, hear and remember what happened.

Bernard Jackson was found guilty and sentenced 5 years’ prison because           .

    A．the victims insisted that he was the attacker

    B．the admitted the crime of raping two women

    C．the police discovered evidence leading to his guilt

    D．the eyewitness proved the victims’ testimony

The following statements may be the reasons for why sometimes the eyewitness’ testimony is not accurate EXCEPT          .

    A．the eyewitness is confused by the police’s questions

    B．the eyewitness is shown photos of many similar faces

    C．the eyewitness lacks the professional help from police

    D．the eyewitness can’t identify people of other races clearly

．An inaccurate eyewitness testimony may lead to         .

    A．the misunderstanding of the case B．the disbelief in the court

    C．the disrespect for the eyewitness    D．the conviction of an innocent person

Eyewitness testimony is important because         .

    A．it can be relied on to detect criminals in all cases.

    B．it is sometimes the only way to resolve court cases.

    C．it is sometimes the only clue for police investigation.

    D．it is more reliable than physical evidences to a crime.

    Next time a customer comes to your office, offer him a cup of coffee. And when you’re doing your holiday shopping online, make sure you’re holding a large glass of iced tea. The physical sensation(感觉) of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

    Psychologists have known that one person’s perception(感知) of another’s “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies’ conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow’s work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study’s hypotheses(假设), handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly,” says Bargh.
