     Many people believe that French people are very different from Americans. This is certainly true where
eating habits are concerned (有关的)! According to a report by the World Health Organization (世卫组织),
each year French people eat four times more better than Americans. In addition, they eat more vegetables,
potatoes, grain and fish. Yet, despite (不管) the fact that they eat larger amounts of these foods, the French
take in about the same number of calories each day as Americans. French and American men consume (消耗)
about 2,500 calories each day on average. French and American women take in about 1,600 calories daily.
      How can this be? If the French are eating more of certain types of foods, shouldn"t this add up to more
calories?And why are so few French people overweight compared to Americans? The answer is that
 Americans consume 18 times more refined (精制的) sugar than the French, and drink twice as much
whole milk!
      Although many Americans believe the French end up each meal with gooey (胶粘的) desserts, this just
isn"t so. Except for special occasions, dessert in a typical French home consists of fresh fruit or cheese.
Many American families, on the other hand, like to end their meals with a bowl or two of ice cream or another
sweet treat.
1. Name six types of foods that French people eat more of each year than Americans.
     ______________________________________________________________________________.
2. How many calories does the average Frenchman consume each day?
     ______________________________________________________________________________.
3. How much whole milk does the average French person drink compared to the average Americans?

4. How much more refined sugar do Americans eat than the French?
     ______________________________________________________________________________.

     Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams
are like short films. They are usually in color. Some dreams are like old films. They come to us over and
over again. That may be because the dreamer is worrying about something. Dreaming may be a way of
trying to find an answer. Some people get new ideas about their work from dreams. They may have been
thinking about their work all day. These thoughts can carry over into dreams. Sometimes we wake up with
a good feeling from a dream. But often we can"t remember the dream. Dreams can disappear (消失) quickly
from memory.
     Too much dreaming can be harmful (有害的). The more we sleep, the longer we dream. The mind is
hard at work when we dream. That is why we may have a long sleep and still wake up tired.
