A glass a day keeps obesity at bay. Alcohol has always been thought to cause weight gain because of its high sugar content, but new research suggests a glass a day could form part of a diet. Looking at past studies they found that, while heavy drinkers do put on weight, those who drink in moderation can actually lose weight.
A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain”. The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that current data do not clearly indicate if moderate drinking increases weight.
Boston University’s Dr. Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood. His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病),which relate to increasing obesity. Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.
The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods. They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.
For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese. What’s more, a study three years ago suggested that resveratrol, a compound present in grapes and red wine, destroys fat cells.The passage is mainly for those ______.

Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time that there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.
According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons. The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking ” has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs, today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty–five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.According to Anderson, before 1970, Americans had little idea about ________.
A.the social movement |
B.environmental problems |
C.recycling techniques |
D.the importance of Earth Day |
Where does the support for environmental protection mainly come from?
A.The business circle | B.Government officials |
C.The grass–roots level | D.University professors |
What have Americans achieved in environmental protection?
A. They have cut car emissions to the lowest.
B They have reduced pollution through effective measures.
C. They have lowered their CO levels in forty cities.
D. They have settled their environmental problems.What is especially important for environmental protection according to the last paragraph?
A.Planning | B.Education |
C.Green living | D.CO reduction |

Country music is one of the most popular kinds of music in the United States today because it is about simple but strong human feelings and events---love, sadness, good times, and bad times. It tells real-life, stories and sounds the way people really talk. As life becomes more complicated(复杂), it is good to hear music about ordinary people.
Country music, sometimes called country-western, comes from two kinds of music. One is the traditional music of the people in the Appalachian Mountains in the eastern Unite States. The other is traditional cowboy music from the west. The singers usually play guitars, and in the 1920s they started using electric guitars. At first city people said country music was low class. It was popular mostly in the South. But during World War II, thousands of Southerners went to the Northeast and Midwest to work in the factories. They took their music with them. Soldiers from the rest of the country went to army camps(军营)in the South. They learned country music. Slowly it became popular all over the country.
Today country music is also popular everywhere in the United States and Canada—in small towns and in New York City, among black and white, and among educated and uneducated people. About 1, 200 radio stations broadcast country music twenty-four hours a day. English stars sing it in British English, and people in other countries sing it in their own languages. The music that started with cowboys and poor southerners is now popular all over the world.It can be learned from the passage that country music comes from_____ .

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.The passage is mainly about _____________.
A.color and its surprising effects. |
B.women being luckier than men |
C.danger caused by color blindness |
D.some information on color blindness |
According to the passage, with the help of the “cones”, we can ___________.
A.tell different shapes | B.see in a weak light |
C.kill mosquitoes | D.tell orange from yellow |
Why do some people say it is safer to be driven by women?
A.Women are more careful. |
B.There are fewer color-blind women |
C.Women are fonder of driving than men. |
D.Women are weaker but quicker in thinking. |
Which of the statements about the color- blind is true?
A.Neither men nor women can see deep red. |
