A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities (个性) and food experiences. “One week later,” Loftus says, “we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences.” Some accounts included one key additional detail (细节): “You got sick after eating strawberry ice-cream.” The researchers then changed this detail into a manufactured (人为促生的) memory through leading questions—Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it.

    When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work only for foods you don't eat on a regular basis. But most important, it is likely that false memories can be implanted (灌输) only in people who are unaware of the mental control. And lying to a patient is immoral, even if a doctor believes it's for the patient's benefit.

    Loftus says there's nothing to stop parents from trying it with their overweight children. “I say, wake up—parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that's a more moral lie. Decide that for yourself.”

72. Why did Loftus ask the volunteers to answer some questions?

    A. To improve her computer program.           B. To find out their attitudes towards food.

    C. To find out details she can make use of             D. To predict what food they'll like in the future.

73. What did Loftus find out from her research?

    A. People believe what the computer tells them.

    B. People can be led to believe in something false.

    C. People tend to forget their childhood experiences.

    D. People are not always aware of their personalities.

74. According to the study, people may stop having a certain food if they ________.

A. learn it is harmful for health                        

B. lie to themselves that they don't want it

    C. are willing to let doctors control their minds

    D. think they once had a bad experience of eating it

75. What is the biggest concern with the method?

    A. Whether it is moral.                                B. Who it is best for.

    C. When it is effective.                                D. How it should be used.

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   

       D．Skin Cancer Caused by Freckles

A new weapon (武器) is on the way in the fight against smoking in Europe. Soon when smokers buy cigarettes they might see a shocking photo of a blackened lung or a cancer patient staring back at them from the packet.

Some boys may think of smoking as cool and sexy. Their friends won’t agree when they see their packets of cigarettes lying on the table. The European Union announced that it had chosen 42 photos that showed the damage cigarettes could do to the body, calling on member nations to put these pictures on packets to discourage smokers. To catch the attention of teenagers, the special packets warn of long-term medical dangers, like cancer. Short-term effects, like bad skin, are also on the list.

“The true face of smoking is disease, death and horror. That is the message we should send to the young,” said David Byrne, an EU health official. “Hopefully these pictures will shock students out of their love for cigarettes.”

The EU head office hoped the pictures would work better than current (当前) written warnings on packs of cigarettes. The warnings included “smoking kills” and “smoking can lead to a slow and painful death”.

So far, Ireland and Belgium have shown interest in the photos. Canada has used similar pictures and warnings on cigarette packs since 2000. The country has recently seen a fall in the number of smokers. According to studies, smoking is the single biggest cause of avoidable deaths in the EU. Every year more than 650,000 smokers die, more than one person a minute.

By saying “a new weapon is on the way”, the writer means the EU is going to have _____ .

   A. the true face of smoking shown everywhere                     

   B. shocking photos printed on cigarette packets      

   C. written warnings printed on the cigarette packs                      

D. pictures put up where cigarettes are sold                            

The pictures chosen by the EU are supposed to mainly work on _____ .

   A. young smokers                  B. smokers in Ireland and Belgium

C. male smokers                   D. young smokers’ friends

What can we learn from the passage?

   A. Canada has been the first to use the EU’s “weapon”.            

 B. Most smokers don’t quite believe the written warnings.  

C. The new form of warning has already been proved to work.

D. Smoking has caused more deaths than anything else in the EU.

Which of the following would be the best title for the passage?

   A. Smoking Is Cool And Sexy.        B. A New Weapon to Fight Smoking.

   C. Young Smokers in The EU.        D. Deaths from Smoking.

A long road leads through the woods to Don Robinson’s unfinished house. Wearing dirty sneakers and a shirt with holes, Don Robinson is an 81-year-old Missouri businessman. Although he’s rich, he didn’t use his money to buy himself a grand home. Instead, he used it to buy wild land.

Robinson has decided to donate 843 acres of his own personal wilderness to the Department of Natural Resources after his death, which can then be used to create a new state park. His generous donation is the same size as New York City’s Central Park. It is said that it’s the largest land donation to happen in the last 25 years.

How did he come up with this idea? For Robinson, the idea of donation came from his respect for the land and the environment. He doesn’t have children to pass it onto. He hoped that someone would make full use of it, or the land would probably turn into wasteland. A green park filled with trees can at least help deal with global warming, in addition to producing fresh air.

Robinson has lived here in a small wooden house since 1964．One room holds his bed, a few chairs and a desk. He said he didn’t care how much his donation was worth. Tom Pounders who used to work for Robinson said, "He doesn’t think material objects are important.” He also recalled that Robinson once repaired a broken tennis shoe with a spare tire.

Robinson has just one request for the new park that will be established after his death. He’d like it to be named the Don Robinson State Park. "There’s a lot of Robinsons, but only one me. It would be nice if people remembered to use my full name when walking through the park," he said.

In paragraph 2, the underlined word “wilderness” refers to _______.

       A．wild animals           B．wild land         C．wild plants       D．wild wounds

Don Robinson has decided to donate _____ to the Department of Natural Resources after his death.

A child-like robot, Wakamaru, developed by Mitsubishi Heavy Industries of Japan and combining the roles of nurse, companion and security guard, will soon be in the market to look after the growing number of old people with no one to look after them.

  Cameras implanted under the “ eyebrows” of the robot enable it to “see’’ as it moves around in a house. The images can be sent to the latest mobile telephones, which can show the pictures. Wakamaru speaks with either the voice of a boy or a girl. It is also designed to provide companionship, greeting its “ papa”, when he comes home. Based on a vocabulary of around 10 000 words, it is the first household robot which is able to hold simple conversations. It can not only speak, but also understand answers and react accordingly. It will ask“ Are you all right?” if its owner does not move for some time. If the answer is no, or there is no answer, it will telephone preset numbers, send images and work as a speakerphone. It can recognize up to 10 faces. It can be set to remind forgetful people when it is time to take medicine, eat and sleep.

  However, like most robots, it cannot climb stairs. Mitsubishi developed Wakamaru from robots which have already been made to go around nuclear power facilities(设施). “ Looking at the ageing of society and the falling birth rate we decided that this could work as a business. We want to offer it as a product that helps society,’’ said the project chief. The developers plan to sell the robot from April next year at between 5,000 and 6,000 pound.

  The life expectancy of Japanese women has shot up to almost 85, the highest in the world. At the same time, extended families are being replaced by nuclear families. This has left many Japanese anxious about their elderly parents. Therefore, the technology has gained nation-wide publicity in Japan.

Which of the following is TRUE about Wakamaru?

It is used in some nuclear power facilities.

It can speak but cannot understand answers.

It can go up and down the stairs easily.

It can recognize as many as 10 people.

The passage is written with the purpose to ______.

      A. introduce a new product  

B solve the aging problems.

     C. tell people how to use the robot 

     D show the rapid development of technology

What can be inferred from the passage ?

      A. The robot can dial proper numbers for help

      B. The robot is likely to have a promising market.

      C. The robot enables the Japanese to live longer

      D. Many elderly Japanese are anxious about their future
