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 factory that turns used wine bottles into green sand could revolutionize the recycling industry and help to filter（过滤）the nation's drinking water.
For the last 100 years special high grade white sand quarried（开采）at Leighton Buzzard in Bedfordshire has been used to filter tap water to remove bacteria and impurities—but this may no longer be necessary.
The green sand has already been successfully tested by water companies and is being used in 50 swimming pools in Scotland to keep the water clean.
Backed by one million pounds from the European Union and the Department for Environment, Food and Rural Affairs(Defar),a company based in Scotland is building a factory to turn beverage bottles back into the sand from which they were made.
The idea is not only to avoid using up increasingly scarce sand in Scotland and avoid any further quarrying but also to solve a crisis in the recycles only 750 000 tones of it.
Howard Dryden, the scientist and managing director of the company has spent six years working on what he calls Active Filtration Meadia, or AFM, the recycled glass. He says he needs bottles that have already contained drinkable liquids to be sure that drinking water would not be polluted.
"The fact is that tests show that AFM does the job better than glass, it is easier to clean and reuse and has all sorts of properties that make it ideal for other applications, "he claimed. He also thinks the market will be able to take 250 000 tones of green sand a year. The plan is to build five or six factories in cites in UK where the bottles come from to cut down on transport.
The factory will be completed this month and is expected to go into full production on January 14 next year. Once it is providing a "regular" product, the government's drinking water inspectorate will be asked to perform tests and approve it for general use by water companies.

【小题1】Why did Loftus ask the volunteers to answer some questions?

A punctual person is in the habit of doing a thing at the proper time and is never late in keeping an appointment．The unpunctual man, on the other hand, never does what he has to do at the right time． 【小题1】
There's a proverb which says，“Time flies never to be recalled．” This is true．【小题2】The unpunctual man is forever wasting his most valuable possessions as well as others'．The unpunctual person is always complaining that he finds no time to answer letters, or return calls or keep appointments．【小题3】 He knows that he can get through his huge amount of work only if he faithfully keeps every appointment and deals with every piece of work when it has to be attended to．
【小题4】 ．If a person is invited to dinner and arrives later than the appointed time, he keeps all the other guests waiting for him．Usually this will be regarded as rude both to the host and the other guests．
Unpunctuality, moreover，is very harmful when it comes to one's duty．Imagine how it would be if those who are put in charge of important tasks failed to be at their proper place at the appointed time．【小题5】
