15．The latest fashion in the kitchen is the food steamer．All the stores are selling them；everyone wants one．Steaming is one of the simplest and healthiest ways of cooking food．However，that cooking time is usually longer than with other methods．In case you're thinking of buying a steamer，I've done a survey about the steamers available on the market to help you decide which will suit you best．
Folding Steamer
The simplest and least expensive is the folding stainless-steel（不銹鋼）version．
Advantages：This is a good，basic design which sits inside a variety of different shapes of  pans with the water under it；a ring in the centre allows for easy lifting and it's easy to clean．
Disadvantages：It only holds small dishes．Also，if you put too much water in the pan，it will boil up through the vegetables and they will be watery．If you put too little water in and let it get dry，you will burn the pan and get strange-smelling vegetables．
Steaming Pan
This is a three-layered black Teflon-coated version with a lid and two double-handled  steamers，which sits on the oven ring．The brand I bought is called Nutritious Living．
Advantages：This is an excellent steamer，lightweight，easy to clean，and of all the steamers I've tried，this cooks the fastest．Fish and chicken can be cooked on the bottom with rice or vegetables on the top．It's easier to store．
Disadvantages：Water can boil away until the pan is dry，but if you make sure you fill the  pan up to the suggested level and do not overcook the food，this should not happen．You cannot  see the food cooking from the top．It doesn't supply a dish for cooking rice．
For serious users of steamers，I recommend having one of each version．If you just want  to try it，get the folding stainless-steel type．

21．The food steamer is popular with people becauseB．
A．it can save time and money
B．food can be cooked simply and healthily
C．it is easy to clean and store
D．it is available in any store
22．Which of the following is true about the folding steamers？A
A．They are cheap and easy to use．
B．They are difficult to clean．
C．They can hold all kinds of dishes．
D．You can put little water in the pan．
23．When you use the steaming pan，D
A．you can overcook the food
B．you can only cook rice
C．you feel it's heavy to carry
D．you should pour proper amount of water．

6．Life expectancy is rising in much of the world．But doctors are seeing another trend that isdisturbing．Some people are choosing lifestylesthat contribute to early death．A new U．S．studylooks at four lifestyle choices that prevent people from staying healthy and living longer．
It used to be rare for people to live to 100．Butbabies born in the U．S．today can hope to live thatlong．In the 20th century，life expectancy in wealthy nations increased by as much as 30 years．Average life expectancy for Americans is 78．But doctors are seeing people adopt bad habits that can cut their lives short…like eating toomuch or eating too much junk food，exercising too little and smoking cigarettes．These habits increase the risk for cancer，diabetes，heart disease and stroke．
Researchers at Harvard University and the University of Washington wanted to find out howmany years are lost with these lifestyle choices．"What we found was that high blood pressure，smoking，overweightaccount for five years ofloss of life expectancy in men and about four years in womenat the national   level，"Goodarz Danaei，one of the principal researchers said．The researchers broke down the data into race，income and locale and they found even greaterdifferences．Middle-income whites have the best blood pressure．But Asian-Americans have fewest badhabits and the best health．"They are not getting  heart disease because of low blood pressure，they are not getting cancer  because they have low risk factors for cancer，including smoking，"Danaei said．
The researchers say public health officials could use the study to plan programs that will help people make better lifestyle choices．

3．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（生物學(xué)機(jī)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．

66．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
67．The underlined phrase"in moderation"in the first paragraph meansA．
A．properly          
B．carefully         
C．excitedly          
D．frequently
68．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．
69．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．
70．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．Experts estimate that one out of every five fish sold was caught illegally．It threatens（威脅） food security and hurts the environment．Officials are using new observational technology to fight illegal fishing．
"Thank you for taking the time to join us here in Harwell （UK） in the Operations Center to what we call‘Project Eyes on the Seas．'"says Tony Long，who leads the Ending Illegal Fishing program for Pew Charitable Trusts．The group created Project Eyes on the Seas．Large three-dimensional images of a globe can be seen on a video．

Mr．Long says that permits researchers to understand exactly where the fishing boats are operating．The Pew team gives the information it gathers to port officials to help them decide if they should take action against a ship．Tony Long says he would like to be able to provide port officials all over the world with clear lists．They would inform the officials about ships to inspect，ships to bar from entrance，and ships to permit entrance for trade activities．
The Pacific island nation of Palau was an early user of the technology．Palau has one of the richest fishing areas in the world．Last year，it announced a plan to ban commercial fishing in a 630，000square kilometer area．K．B．Sakuma is a special adviser to the president of Palau．He says Palau is trying to deal with a recent increase in illegal，unsupervised（無(wú)人監(jiān)管的）and unreported fishing．
"And it's come to a headin the last year or two．From our southern island in the evening you can see on the horizon just dotted lights of these illegal fishermen that come into our waters，fill their ships with our fish，our resources，our food security…"

20．Spending hours playing violent video games prevents teenagers from their moral growth，a study has found．It is thought that regular touch to violence and lack of contact with the outside world makes it harder for them to tell right from wrong．They also struggle to trust other people，and see the world from their viewpoints．
    Researchers from Brock University in Ontario found that those who spend more than three hours each day in front of the screen are particularly unlikely to have developed the ability to empathise（同情）．
    The Canadian researchers surveyed 109 boys and girls，aged 13 and 14，about whether they played video games，which games they liked，and how long they spent playing them．Their findings found that 88 percent of teens said they played games，and more than half admitted to playing games everyday．Violent games were among the most popular．
    The teenagers also filled in a questionnaire designed to measure their moral development．For example，they were asked how important it is to save the life of a friend．
    Previous studies have suggested that a person's moral judgement goes through four phases as they grow from children and enter adulthood．By the age of 13 or 14，scientists claim young people should be entering the third stage，and be able to empathise with others and take their viewpoints into account．The research found that this stage appeared to be delayed in teenagers who regularly played violent video games．
    It is also thought that teenagers who play games regularly did not spend enough time in the real world to learn to take other's thoughts into consideration．Researcher Mirjana Bajovic said："The present results indicate that some teenagers；who spent three or more hours a day playing violent video games，are deprived of such opportnnities．"Writing in the journal Educational Media International．the researchers added："Touch to violence in video games may influence the development of moral reasoning because violence is not only presented as acceptable but is also justified and rewarded．"
    They concluded that rather than trying to enforce an‘unrealistic'ban on the games，parents and teachers should encourage teenagers to do charity work and take up after-school activities．

61．What would be the result of playing violent video games？D
A．Making teens easy to get along with．
B．Helping teens make more good friends．
C．Causing teens easier to tell right from wrong．
D．Getting teens hard to take others into consideration．
62．Why did the Canadian researchers carry out the studies？B
A．To discuss how to save the life of a friend．
B．To measure teenagers'moral development．
C．To enrich teenagers'awareness of social life．
D．To develop teenagers'ability to communicate．
63．What call we know from the words of Mirjana Bajovic？A
A．Vio1ent games cost teens social experiences in real life．
B．Playing games regularly will improve teens'intelligence．
C．Playing games inspires teens to develop fast．
D．Playing games makes teens help others．
64．What can be inferred from the text？D
A．Parents and teachers should let teens go online．
B．Playing video games should be forbidden among teens．
C．Game designers should be kindly treated and rewarded．
D．Teens should be encouraged to do more meaningful things．
65．Which of the following would be the best title of the text？A
A．Violent video games affect teenagers'moral development
B．Vio1ent video games delay teenagers'physical growth
C．Violent video games should be forbidden among teenagers
D．Violent video games reduce teenagers'chance in the real world．

7．"Drink your milk．It is good for you!"You've probably heard that many times，and it is true．Milk contains calcium，which is a necessary nutrient for keeping bones and teeth healthy and strong．The US government even requires milk as part of the National School Lunch Program，saying that students should drink one cup of fat-free milk at each meal．
Last Thursday，however，a group of doctors asked the government to remove the lunch program．The Physical Committee for Responsible Medicine says，"Milk is high in sugar，high in fat and high in animal protein，"all of which have negative effects on health．The PCRM says there were better and healthier ways to get calcium such as eating beans，broccoli，cereals and tofu．Orange juice and soymilk that have calcium added to them also supply the nutrient．"One of the only reasons people talk about dairy，or promote it at all，is because it is going to help build strong bones．"says Dr．Neal Bamard，president of the PCRM．But milk may not be the best way to get calcium your body needs．
Of course，calcium is important for health bones and teeth，but there are other things that affect your bone strength，such as genes，how much vitamin D you take in and getting an hour's worth of exercise every day．
Some nutritionists disagree with the idea that milk isn't important．Keri Gans，a dietitian，says，"I think it is irresponsible to take this beverage that children enjoy，especially among those who are unable to meet their nutrient needs for the day，and remove it from lunch time．"
The US government is studying the request of the PCRM，but a decision may be a one way to take off．Meanwhile，Marion Nestle，a professor at New York University，put it best："Milk demonstrably has nutrients．Other foods have the same nutrients．It's just a food．Like other foods，too much might be a problem．"
29．Why does the US government ask students to drink one cup of milk at lunch time？
D
A．They have been told many times．
B．They have taken the PCRM's advice．
C．Fat-free or low-fat milk is less expensive．
D．Milk helps build students'strong bones．
30．Which of the following opinions does the PCRM support？A
A．Milk is harmful to students'health．
B．Students should drink more milk each day．
C．Orange juice is higher in calcium than milk．
D．Milk is the best way to get calcium．
31．The underlined word"beverage"in Paragraph 4 most probably meansC．
A．gene        B．idea       C．milk       D．lunch
32．What does the above text mainly talk about？D
A．The best way to get the most calcium．
B．The connection between milk and health．
C．Different opinions about the importance of milk．
D．Whether to take milk off the school-lunch menu．
