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 .

If you cut in line, you might just be a bad person. The queue is a regulation where the reward (the ice-cream stand/dining room/ticket booth) is earned through patience. Your choice to avoid this time-honored process will be bound to draw the anger of those you pass by, drawing remarks like “Whoa there, Chief,” the passive-aggressive “There’s a line, you know!” and of course, the incredibly common “Hey, Copernicus, why don’t you guide yourself to the back of the line?”
But, in the moment in which you really cannot wait, for example, the entire royal family has prepared a dinner party upon you last minute, then there is a way to cut the line correctly.
There are a few different ways to consider and a few different methods to employ. The regularity of the situation is very important. If you’re waiting to use the photocopier at work, you might be more likely to manage a successful cut than if you were waiting for a lifeboat on the Titanic. Sure, that might be an extreme example. But the importance of the event does matter.
For those requests in normal situations, emphasizing either the urgency of your task or the simplicity of your task proved to be effective: experimenters who said “Excuse me, I have five pages. May I use the photocopier?” had a cut rate of 60 percent and experimenters who said “May I use the photocopier because I need to make copies?” saw a success rate of 90 per cent when queuing for the copy machine.
If you have a couple of extra dollars lying around, bribing members of the line also proved to be effective. And most of the time, the person being bribed didn’t end up accepting the money, because even the offer showed that the briber had a sense of desperation.
1.Why does the author use the remarks about Chief and Copernicus in paragraph 1?
A.To illustrate the reaction from members in line. B.To encourage those who want to cut in line.
C.To praise the behavior of cutting in line. D.To provide advice which helps cut in line.
2.Which of the following is not a wise way to cut in line?
A.Giving the members in line money. B.Stating the emergency of the event.
C.Considering the regularity of the situation. D.Defending the right of cutting in line.
3.What is the best title for the text?
A.Be Patient When Queuing. B.Acceptable Ways to Cut in Line.
C.Time and Tides Waits for No Man. D.Special Rights under Emergency.

Jules is now in his sixties, and is one of the many homeless people who live on the streets; he buys a newspaper most days. Today, with his fellow tramps, he reads about yesterday's student demonstrations.
Like many of the tramps who live under the bridges, Jules was not always so poor. A long time ago he was in the Navy, and like many who have been to sea for a long time, he has stayed slim and fit. Despite the strict organization on board ship, he loved his life, and had the opportunity to see many countries. He visited Poland and Russia; in South Africa he realized what he valued in each country was the people he met. He was always astonished and delighted by the ways in which the people he met differed from one country to another. Some day, he hopes, everyone will see the world as he does.
After many happy years in the Navy, he had to retire. The good things in life always come to an end. His mother and father had long since died and he’d lost touch with his other relatives. He became an industrial designer. He was happy, although it wasn’t the same as the sea. He never wanted to get married and have children.
And then there was the period of darkness. He smiles sadly. He shrugs his shoulders and looks at his hands. There are tears in the corners of his eyes. This is something that he cannot bring himself to talk about. ''It all went wrong, '' he whispers.
He was silent for a while, then recovered. He began to talk more loudly. ''Look at me now---it makes me angry. And what about the President? He's been in power for years, and look what he's done for us. Nothing! I am still out on the streets and live the life of a dog.''

Summer is here, and with it comes a chance you'll get too much sun. While there's no cure for sunburn, a small but fascinating new study suggests taking large amounts of vitamin D after exposure may prevent the associated redness and inflammation (发炎).
In the paper, researchers exposed 20 volunteers to a light resembling solar radiation to induce a sunburn on a small piece of skin. They then gave the ''burn victims'' large amounts of vitamin D, and followed up with participants one, two and three days (and a week) later to measure skin redness and thickness. The researchers found that vitamin D decreased inflammation and redness, compared with taking a placebo (安慰剂). And this effect increased in proportion to how much was consumed. Vitamin D also appears to increase the activity of a gene called arginase-1, which is involved in tissue repair and healing. Taking 50, 000 international units (IU) of vitamin D--125 times the recommended daily allowance-led to a significant reduction in redness and inflammation, compared with the placebo. Those who took 100,000 IU had even less redness and pain; and those who took 200, 000 IU had the greatest reduction in inflammation.
This is the first study to show vitamin D can reduce inflammation, and suggests that it ''could potentially help prevent sunburn, '' says senior author Kurt Lu, a physician scientist and assistant professor at Case Western Reserve University.
It used to be thought vitamin D was primarily involved in building healthy bones and muscles, but recent research has found it has many more roles, including influencing inflammation, such as the kind associated with sunburns.
So, if you get burned, should you take a lot of vitamin D? The study authors don't recommend it. ''I think that's probably not a good idea and not well established by this study, '' says Barbara Gilchrest, a physician scientist at Massachusetts General Hospital. Such large amounts, if taken repeatedly, have the potential to cause vitamin D toxicity (毒性).
1.What does this passage mainly talk about?
A.An unusual method for relieving sunburn.
B.Tips for how to travel safely in summer.
C.A suggestion on taking vitamin D properly.
D.Advice on how to take medicine effectively.
2.How do the researchers confirm the healing effect of taking vitamin D?
A.By observing the inflammation of skin every day.
B.By measuring the thickness of skin after a week.
C.By increasing the daily volume of vitamin
D.By comparing the effect with that of placebo.
3.Figures are used in paragraph 2 in order to ______.
A.recommend the daily intake
B.argue against the benefits of more Vitamin D
C.show the more Vitamin D, the greater benefits
D.stress the potential danger of too much Vitamin D
4.What can be inferred about the function of vitamin D?
A.Repeatedly taking large amounts of Vitamin D is beneficial.
B.Vitamin D may bring more advantages to us than what has been found out.
C.Don't take vitamin D unless your doctor approves you to do it.
D.Vitamin D is more useful for curing sunburn than building healthy bones.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
Every night after dinner, my grandparents would turn on TV for the 6 o'clock news. No matter how hard I tried to act the grown-up and watch with them, I would inevitably(不可避免地) get distracted until 6:30 when Wheel of Fortune came on.
My grandma would play along, trying to guess the answers before the players. Her shouts of excitement when she succeeded could be heard across the house.
As I grew older, my love of reading and writing blossomed, and I would join my grandma in yelling out letters. Soon, I was experiencing the thrill of solving the puzzles faster than the contestants(选手) and even my grandma. I was hooked.
Due to constant moving around with my mom and father, I started to spend less time with my grandparents, but our bond remained strong. My grandparents provided me with the stability, love and support that I desperately needed when I grew up. When I was in a bad mood, I would remember those sweet nights.
A few years later, I was living with my grandpa in Chicago. While watching an episode(集) of Wheel of Fortune, we had a wave of nostalgia(怀旧). With application, I didn't think much of it until I received a mail months later, announcing that the Wheel of Fortune casting team would come to Chicago. In order to be considered for an in-person audition(试演), applicants would need to submit a sixty-second video explaining why they wanted to be a contestant.
All my childhood memories of watching the show came flooding back, and I knew I was meant to spin(旋转) the wheel for real. Immediately, I recorded a video and submitted it. A couple of weeks later, I received an e-mail inviting me to audition in person. I was very nervous on the audition day. I couldn't believe I was trying out for ''America's Game''! After two rounds of intense auditioning, with half of the hopefuls letting go after the first round, it was over. All of us applicants were told we would receive a letter in the mail within two weeks if we were selected.
