15.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.
31.The passage is mainly for thoseD.
A.who produce wine                      
B.who are eager to lose weight
C.who go on a diet                      
D.who have a drinking habit
32.The underlined phrase"in moderation"in the first paragraph meansA.
A.properly          
B.carefully         
C.excitedly          
D.frequently
33.Why has alcohol been thought to cause weight gain?B
A.Because its calories are stored in fat.
B.Because it is rich in sugar.
C.Because it changes drinking patterns.
D.Because it increases the risk of diabetes.
34.What can we learn from the passage?C
A.The specific roles of different types of alcoholic drinks are very clear.
B.Resveratrol is proved to increase the risk of becoming fat.
C.The research found moderate drinking has a strong protective effect.
D.Current data clearly show that moderate drinking increases weight.
35.What is most likely to be discussed in the paragraph that follows?B
A.How to do some easy experiments.
B.How to prove the finding mentioned above.
C.How to make wine in a healthy way.
D.How to reduce the calories contained in wine.

10.Most scientists are now certain that global warming is taking place.Gases such as carbon dioxide produced by burning of coal,oil,wood,together with industrial pollution,are creating a warm blanket around the earth.This blanket is trapping heat in the atmosphere and raising the temperature of the earth.
The evidence for global warming can now be seen in the world's changing climate statistics.In Europe,eight of the last ten years have seen record high temperature.For northern Europe,this has generally been a change for the better.Gardens can even now grow tropical plants in England,though London may never see a"White Christmas"again. On the other hand,the countries around the Mediterranean Sea,and those south of the Sahara desert are receiving even less rain than before.In sub-Saharan Africa the crops are drying out in the fields and people are dying of starvation.In America,the climate is becoming more extreme-the summers are getting hotter and hotter and the storms are becoming more violent.In 1999the southern United States was struck by a series of destructive hurricanes,while the end of 1999saw the worst floods ever in Venezuela.Meteorologists expect such trends to continue,and indeed to worsen,if global warming cannot be halted(终止的).
In addition to worrying about rising global temperaturesand more extreme weather conditions,scientists are closely monitoring sea levels around the world.These are slowly rising,as the northern and southern polar ice-caps start to melt.This will have serious consequences for lowlying countries near the sea,such as the coral islands in the Pacific,and Bangladesh where the River Ganges already folds the delta every year.Already parts of these places have disappeared under the rising tides.
4.What is probably the best title for this passage?A
A.The Effects of the Global Warming
B.Temperature of the Earth Is Rising
C.More and More Hurricanes
D.Global Warming Is Becoming More Serious
5.According to the passage,global warming can't causeC.
A.the rising of the temperature in some regions
B.bad weather conditions
C.more carbon dioxide
D.the rise of the sea level
6.Which of the following statements is NOT true?A
A.Carbon dioxide creates a warm blanket around the earth.
B.Record high temperature can often be seen in Europe.
C.The water is becoming much in the North and South Polar.
D.If global warming continues,the weather conditions will be much worse.
7.The underlined sentence in the second paragraph means thatA.
A.the tropical plants can grow better in England
B.gardeners have a better skill to plant the tropical plants
C.tropical plants can grow in England due to the rising temperature
D.the tropical plants couldn't grow well in the England in the past.

4.In Shanghai,the historic Bund(外滩)catches much attention---many former banks and trading houses along the Huangpu River,built a century ago in different architectural styles,are monuments to the grandeur(辉煌)of that era.It can also suffocating(令人窒息的)on weekends,with tourists struggling for taking photos.
For local residents,another part of the riverfront now known as the West Bund has become a far more appealing place to spend the weekend.Here,a once industrial area known for aircraft manufacturing(制造)has been transformed into a green corridor where local residents come to ride bikes or enjoy picnics on the grassy riverbank.
In the last two years,museums and galleries have also started popping up as part of the city's plan to turn the West Bund into a world-class art and culture center.

To achieve this,the city has built may museum buildings,including the Shanghai Natural History Museum,designed by the American architects,and the Power Station of Art,a Tate Modern-inspired art museum in a former power plant that hosted a show of the Chinese artist Cai Guoqiang's drawings.
Across the river,two former exhibition halls from the 2010World Expo have also been transformed into museums---the oversize glossy-red former China Exhibition Hall is the new home of the China Art Museum.

8.Why are the local residents more interested in the West Bund?C
A.It attracts the world's attention.
B.They can visit aircraft industry there.
C.They can enjoy themselves there at weekend.
D.It shows Shanghai's grandeur int the last century.
9.What does the underlined part in Para.3 mean?D

10.According to the text,the Power Station of Art isA.
A.inspired by Tate Modern
B.showing contemporary works
C.exhibiting Cai Guoqiang's drawings
