The weight-loss world is full of assertions①, rarely proved, that some pill can help you “burn calories while you sleep.” But a recent Dutch study reports that it can be done – simply by eating more lean protein②.

Researchers report for the first time that consuming nearly a third of daily calories as lean protein – for example, lean meats without the skin – speeds up a person’s metabolism③ during sleep and that higher protein intake increases the burning of calories and fat during the day. Plus, when the study’s participants, who were all women of healthy weight, ate more protein, they felt fuller, more satisfied and less hungry than when they consumed a diet with the amount of protein, about 10 percent of calories.

The findings suggest that adding lean protein to your daily food “enables you to reach the same level of satiety④ that you are used to with about 80 percent of your normal energy intake,” notes Margriet Westerterp-Plantenga. “That means you can eat about 20 percent less and still have the same satiety.”

What gives protein its caloric edge? It’s more difficult for the body to metabolize protein than either fat or carbohydrates⑤. The body also doesn’t store protein as efficiently as it does carbohydrates or fat. So protein is more likely to be burned and that in turn requires more oxygen and helps you feel satisfied in the hours after eating.

But the latest findings don’t mean it’s time to dust off those high-protein diet books. The current study limited fat to about 30 percent of daily calories, and included 40 percent of calories as healthy carbohydrates, including fruit and vegetables. For example, lunch included bread, soy milk, fruit yogurt, tuna in water, tomatoes, cucumbers, feta cheese and salad dressing.

Children start out as natural scientists, eager to look into the world around them．Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment．You only have to share your children’s curiosity．Firstly, listen to their questions．I once visited a classroom of seven－year－olds to talk about science as a job．The children asked me “textbook questions” about schooling, salary and whether I liked my job．When I finished answering, we sat facing one another in silence．Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”

       After a long pause, a boy raised his hand, “Have you ever seen a grasshopper （蚱蜢） eat? When I try eating leaves like that, I get a stomachache．Why?”

       This began a set of questions that lasted nearly two hours．

       Secondly, give them time to think．Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think．When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers．

       Thirdly, watch your language．Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”．These words work well when it comes to encouraging good behavior．But in talking about science, quick praise can signal that discussion is over．Instead, keep things going by saying, “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas．

       Never push a child to “Think”．It doesn’t make sense, children are always thinking, without your telling them to．What’s more, this can turn a conversation into a performance．The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement．

       Lastly, show; don’t tell．Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program．Let children look at their fingertips through a magnifying glass, and they’ll understand why you want them to wash before dinner．Rather than saying that water evaporates, set a pot of water to boil and let them watch the water level drop．

According to the passage, children can answer questions in a more logical, complete and creative way if adults ______．

       A．ask them to answer quickly

       B．wait for one or two seconds after a question

       C．tell them to answer the next day

       D．wait at least for three seconds after a question

In which of the following paragraph（s） does the author tell us what to say to encourage children in a science discussion?

       A．The second and third．   B．The fourth and fifth．

       C．The fifth and sixth．       D．The seventh．

In the last sentence of the first paragraph, the word “lists” could best be replaced by

       A．any questions                   B．any problems

       C．questions from textbooks      D．any number of questions?

The author mentions all of the following techniques for adults to share with their children’s curiosity EXCEPT that adults should ______．

       A．tell their children stories instead of reciting facts

       B．offer their children chances to see things for themselves

       C．be patient enough when their children answer questions

       D．encourage their children to ask questions of their own

The Best of Friends

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image(印象)of unhappy teenagers locked in their room after endless family quarrels.

An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team.” They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation(商议) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”

So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.” My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall.” I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.”Susan Crome, who is now 21, agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework ,I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers’ rebellion is not rooted in real facts. A researcher comments,” Our surprise that teenagers say they get along well with their parents comes because of a brief period in out social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”

What is the popular images of teenagers today?

A. They worry about school                        B. They dislike living with their parents

C. They have to be locked in to avoid troubles         D. They quarrel a lot with other family members

  The study shows that teenagers don’t want to ___

C. go boating with their family                      D. make family decisions

Compared with parents of 30 years age, today’s parents___.

A. go to clubs more often with their children           B. are much stricter with their children

C. care less about their children’s life                 D. give their children more freedom

According to the author, teenage rebellion____.

A. may be a false belief                            B. is common nowadays

C. existed only in the 1960s                         D. resulted from changes in families

What is the passage mainly about?

A. Negotiation in family                           B. Education in family

Birthdays often bring surprises. But this year’s surprise on the birthday of the great British playwright William Shakespeare is __21__ one of the most surprising.

       On April 22, one day before his 441^st birthday anniversary, experts __22__ that one of the most recognizable __23__ of William Shakespeare is a fake (赝品).

       This __24__ that we no longer have a good __25__ of what Shakespeare looked like. “It’s very possible that many pictures of Shakespeare are unreliable because many of them are __26__ of this one,” said an expert from Britain’s National Portrait Gallery.

       The _27_ comes after four months of testing. Experts from the gallery say the image — commonly known as the “Flower portrait” — was actually __28__ in the 1800s, two centuries __29_  Shakespeare’s death.

       The art experts who work at the gallery say they used modern chemistry technology to __30__ the paint on the picture. These checks found traces (痕迹) of paint deep in the picture __31__ about 1814.

       Shakespeare __32__ in 1616, and the date that appears on the portrait is 1609.

       “We now think the portrait dates back to around 1818 to 1840. This was __33__ there was a new interest in Shakespeare’s__ 34__ ,” Tanya Cooper, the gallery’s 16^th century curator (馆长) said.

       The __35__ picture has often been used as a cover for __36__ of his plays. It is called the “Flower portrait” because one of its __37__, Desmond Flower, gave it to the Royal Shakespeare Company.

       “There have always been __38__ about the authenticity (真实性) of the painting,” said David Howells, curator for the Royal Shakespeare Company.

       “Now we know the truth, we can put the image in its proper place in the history of Shakespearean portraiture (画像技法),” he said.

       Two other images of Shakespeare are also being studied as part of the investigation and the results will __39__later in May. But for now what Shakespeare really looked like will remain a __40__.
