It is amusing that yogurt, which was invented to make milk last longer before the days of refrigeration, now makes grocery shopping last longer. Full-fat, or nonfat? Greek, or regular? 1.
A key recommendation when it comes to fat is to choose low-fat or fat-free yogurt. That's because dairy fat is mostly saturated (饱和的), the type linked with increased risk of heart disease. Besides, full-fat dairy has more calories than nonfat.
This view, however, has been challenged by a few recent studies. Researchers think that full-fat dairy might offer some as-yet-unknown health benefits. It might also help with weight management because the fat in it makes it more satisfying, helping keep our appetite in check.
2. Until there are further findings, it might be wiser to choose low-fat or fat-free yogurt and add healthy fat by topping it with nuts.
3. Many of them also have a hard time deciding whether to buy Greek yogurt or regular yogurt. Greek yogurt, which was rare about a decade ago, dominates the store shelves with dozens of flavors today. It has become popular partly because it features a thick, creamy texture (口感) and contains more protein and less sugar than regular yogurt.
Greek yogurt has these qualities because of its unique liquid-removing process. Unfortunately, lots of nutrients, including calcium (钙), are sometimes drained, too. Therefore, thickened yogurt and regular yogurt offer different nutritional benefits. 4.
Finally, it is worth mentioning that it's the added sugar, not the naturally- occurring sugar (which is removed in Greek yogurt), that should be the cause of our concern. Fruit-flavored yogurts that appear to be healthy may have little actual fruit and plenty of added sugar instead. 5.
A.Consumers, however. are not confused only about fat.
B.Mixing them up and enjoying both might be a good idea.
C.With so many conflicting headlines about fat these days, it's no wonder people are confused when buying dairy products.
D.Our best bet might be to buy plain yogurt and sweeten it ourselves using fresh fruit.
E.There are so many choices that we often find it hard to decide which yogurt to buy.
F.They're naturally ''packaged'' with so many important nutrients that it would be misguided to avoid them.
G.Yet more research needs to be done for us to fully understand dairy fat’s health impact .

高三英语七选五中等难度题查看答案及解析
From the moment that an animal is has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in fact, playing a very dangerous game with its environment, a game in which it must make decisions — a matter of life or death.
Animals ability to act reasonably is believed to come partly form what we may call “genetic (遗传性的) learning”, which is different from the individual (个体的) learning that an animal does in the course of its own lifetime. Genetic Learning is learning by a species ---- animals of the same kind ---- as a whole, and it is achieved by selection of those members of each generation that happen to act in the right way. However, the role of genetic learning depends upon how similar the future environment is to the past. The more important individual experience is likely to be, the less important is genetic learning as a means of getting over the problems of the survival game. Because most animals live in ever changing environments from one generation to the next, it is not surprising to find that very few species indeed depend wholly upon genetic learning.
In the great majority of animals, their particular ways of acting in a new environment are a compound (复合体) of individual experience added to the action patterns animals are born with. That is why animals can survive.
1.The animal’s life will come to an end _______.
A. if the animal makes a wrong decision
B. if the animal plays a dangerous game
C. when the animal attacks its enemy
D. when the animal runs too slowly
2.Very few species depend entirely on genetic learning because ________.
A. each generation has its own way of learning
B. their environments change all the time
C. they can act reasonably on their own
D. it takes their whole life to learn
3.When the environment doesn’t change much, ______.
A. animals cannot act in a right way
B. genetic learning is less important for animals
C. individual learning plays a less important role
D. animals cannot get over problems on their own
4.Animals’ living on generation after generation depends on _______.
A. their natural action pattern with their own experience
B. the lessons they have learnt during their lifetime
C. their experience in particular environments
D. the knowledge passed on by their parents

An oral drug, named ERDRP-0519, was invented. It is specifically designed to protect people who got infected measles(麻疹) from spreading the virus to others. Like the flu, measles spreads through the air by breathing, coughing or sneezing. There is typically a time, about two weeks, between becoming infected with the virus and the beginning of symptoms like skin rash(皮疹), runny nose, heavy cough and high fever.
“This therapy application determines the desired characteristics of the drug, which are orally available, cost-effective manufacture and high stability,” Richard Klemperer, professor of Georgia State University, told reporters last Wednesday.
“With these criteria in mind, we have developed a small drug that blocks the measles virus over the past years, which is essential for copy of the virus.”
The researchers tested the drug in rats infected with canine distemper virus(犬瘟病) , which is a close relative of measles virus. They found that all of the infected rats treated with the drug survived the deadly infection, showed no clinical signs of disease and developed a strong protective immune response.
The drug could be used to treat friends, family and other social contacts of a person infected with measles virus, which have not developed symptoms yet but are at risk of having caught the disease, Klemperer said truthfully.
“The emergence of strong antiviral immunity(抗病毒免疫力) in treated animals is particularly encouraging, since it suggests that the drug may not only save an infected individual from disease but contribute to closing measles immunity gaps in a population,” Klemperer said.
The researchers emphasized the drug is not intended as a substitute for vaccination, but as an additional weapon to get rid of the measles. They planned to test the drug’s safety in larger animals, before moving into clinical trials in humans.
“If our next series of studies confirms that the human situation mirrors what we have seen in rats, then this drug may make a major contribution to getting rid of measles by preventing local outbreaks” Klemperer said.
Despite the existence of an effective vaccine, annual measles deaths worldwide have remained constant at around 150,000 since 2007. The reasons for this are the highly infectious nature of the virus, in the developing world largely due to issues of resources, and in many developed countries in particular in the European region due to parental concerns regarding vaccination safety.
1.If a boy got infected by measles virus, he might NOT show the symptom like ________.
A. runny nose B. bad cough
C. high fever D. sick stomach
2. From what Klemperer said, we know that the drug _________.
A. is only intended as a substitute for vaccination
B. can only save those infected individuals from disease
C. is cost-effective and high stability for curing measles
D. has the same effect on human as on larger animals
3.The best title of the passage is_________ .
A. the Introduction of a New Oral Drug
B. the Desired Characteristics of Drugs
C. the Common Symptoms of Getting Measles
D. the Application of Post-exposure Therapy
