    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 I rvine 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.

    根据短文内容，从下框的A-F选项中选出能概括每一段主题的最佳选项。选项中有一项为多余项。

    A. Live below your means

    B. Always stay positive

    C. Educate yourself

    D. Work towards a dream

    E. Developing lasting personal relationships

    F. Stay in shape

    1.____________

    We all want to buy that new piece of technology, treat ourselves to an expensive dinner, or take out a loan for the car we can't afford. It might feel great at the time but hasty（匆忙的）spending hurts a lot later on. Enjoy life's simple pleasures and save as much as you can. Expensive things don't create lasting happiness. Careful spending will bring you greater enjoyment in the long run.

    2._____________

    To be happy we need continuous growth. The best way to grow is life-long education. This doesn't mean you need to pursue a doctorate or spend 2 hours reading every day. Self-education can be anything that takes you out of your comfort zone. The important part is keeping an open mind and searching for fresh ideas.

    3.____________

    Suppose you had everything you wanted. Would you be happy without anyone to share it with? The personal relationships we develop with friends and family members are the greatest source of happiness in our lives. Don't forget about them. Taking the time to develop and enjoy personal relationships is important to long-term happiness.

    4._____________                          

    Even if your life isn't perfect, you can always build toward a goal. The best way to do this is working towards a goal. We can’t control everything about our lives, but working towards a goal gives us something positive to focus on and lays the foundation for future success. No matter what your passion is, get out there and start doing something.

    5._____________

    You only get one body. Once it is ruined, there isn't much you can do about it. Exercise to keep the body working well. Avoid eating too much of damaging substances and unhealthy foods. It may feel terrible at the time but enjoying good health in your later years is worth the sacrifice.
