For example, a small child might ask for a breakfast food that comes in a box with a picture of a TV character. The child is more interested in the picture than in breakfast food. Pictures for children to color or cut out, games printed on a package, or small gifts inside a box also motivate many children to buy products-or to ask their parents for them. Some packages suggest that a buyer will get something for nothing. Food products sold in reusable containers are examples of this. Although a similar product in a plain container might cost less, people often prefer to buy the product in a reusable glass or dish, because they believe the container is free. However, the cost of the container is added to the cost of the product. The size of a package also motivates a buyer. Maybe the package has “Economy Size or “Family Size printed on it. This suggests that the larger size has the most product for the least money. But that is not always true. To find it out a buyer has to know how the product is sold and the price of the basic unit. The information on the package should provide some answers. But the important thing for any buyer to remember is that a package is often an advertisement. The words and pictures do not tell the whole story. Only the product inside can do that. 【查看更多】

    　　We should also know that“greed”is little related to the environmental crisis．The two main factors are population pressures, especially the pressures of large city population, and the desire to bring a satisfactory living with the lowest possible cost to the largest number of people．

    　　The environmental crisis is the result of success in cutting down the death rate of babies, which has given us the population explosion, success in increasing farm output sufficiently to prevent mass famine(饥荒), success in getting people out of the tenements(租房)of the 19th century city and into the ownership of single family home in the suburb，which has given us urban traffic jams．The environmental crisis, in other words, is the result of doing too much of the right sort of thing at large．

    　　To overcome the problems that success always creates, one must build on it．But where to start?Cleaning up the environment requires determined, sustained(持续的)efforts with clear targets and deadlines it needed, above all, concentration of effort．Up to now we have tried to do a little bit of everything, what we ought to do first is to draft a list of priorities(优先解决的问题)．

    Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security.

    New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night.

    The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.

    “We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving,” said lead researcher Dr. Daniel Cohen of Boston’s Brigham and Women’s Hospital. But when those who suffer long-term sleep loss become all-nighters, “the harm is increased ten times,” Cohen said.

    The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.

    It has critically important complicated and unexpected results for anyone who works “crazy hours” and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York’s Montefiore Medical Center. “Don’t think you can just bank up your sleep on the weekend, because it doesn’t work that way,” he warned.

    1.People with long-term sleep loss ______.

    A. are quicker in thinking                   B. may feel refreshed soon after waking up

    C. are surely energetic                         D. can have a strong sense of security

    2.Which of the following is the immediate effect of long-term sleep loss?

    A. Health problems                             B. Immune system

    C. Reaction times                               D. Memory impairment

    3.The underlined phrase “bank up” in the last paragraph most probably means ____.

    A. pile up               B. pick up              C. add up                     D. build up

    4.The text mainly advises people ______.

    A. to sleep more time                          B. to sleep in on Saturday

    C. to sleep scientifically                      D. to sleep little on weekend
