Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing （喘息）．Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others．

Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.

Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don't take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．

Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables'．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．

More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said．

Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．

1.According to the passage, what is the problem with teens who don't get enough nutrients?

In many ways, the earliest periods of photography are the most satisfying. Learning to use the controls is easy and comes quickly, and you can measure the results in terms of sharp and correctly developed pictures. Once you have mastered that, you can start on the second step of your photographic work. Using these basic skills in the wide variety of situations to give the pictures you want, noticing what you see through the viewfinder and turning that into the most effective picture becomes totally interesting.

All good photographs have one thing in common: there is no doubt what the subject of the picture is meant to be. Every photographer must use those same standards to his or her work, not only to finished results but to the subject before he or she takes it. Always work out quite clearly what the subject of the picture is to be and why you are taking the picture. For example, "I am going to take a picture of this street to show the different styles and ages of the buildings and that people have been living, working and shopping in them since time began." By doing this you have a better idea of what to include in the picture and what to leave out. How often have you been shown photographs taken by people away on a trip somewhere? The judgment is always similar, something about "the car park is out of the picture to the left", or "you can't quite see from this picture but if you go up the street". The photographs are usually collections of buildings, people, parked cars, possibly a distant look of an ancient church, and best of all, a figure which you are told is Aunt Henrietta, disappearing in the middle distance. When photographers show you their pictures, they have a clear idea of what they want to bring to your attention, but it often does not appear in the picture. If they had given just a little of their time to think about their future judgment before taking the picture, then the picture would relate its own story. Good pictures can show their subjects quickly and easily.

64. What does the author mean by saying "in many ways, the earliest periods of photography are the most satisfying"?

A. The skills of photography are not as satisfactory nowadays as before.

B. The earliest pictures were the best pictures people have ever taken.

C. The present-day photography depends more on technology than on art.

D. Learning to produce a sharp and correctly developed picture is only the first step in photography and is easily learned.

65. What will it bring you if you decide the purpose of the photograph in advance?

A. It will allow you to leave out unnecessary material.

B. It will allow you to stand in the best place.

C. It will help you to vary the subjects of your pictures.

D. It means you will waste less time.

66. Many photographers fail because ______.

A. their pictures include both buildings and people

B. everything is not clear in their pictures

C. the subjects of their pictures are not obvious

D. the explanation given for their pictures is mistaken

67. What book is this passage most likely taken from?

A. A book on photography for news reporters.   B. A book on how to photograph people.

C. A book on choosing the right camera.           D. A book on improving photographic techniques.

For many of us, printed books are satisfying in ways beyond the words they contain． Billions of printed books have been published, read and saved in the 600 years since movable type was invented, so why mess with a good things?

Sony Electronics is doing just that, betting that readers will be won over by the convenience of readability of its new electronic book devices． Sony's reader, the PRS-505, can hold 160 books in its fixed memory, enough to line the shelves on a good-sized wall in the average American home． The $299 device is about the size of a paperback book, but a half-inch thick and weighs less than a pound．

The Sony reader also lets you store and play or display music． So what's not to like about the Sony? Well, for many bibliophiles, a lot． Book lovers like to have, hold and keep their volumes, which don't need charging． You can write notes in the margins, and enjoy the ambience they provide on your book shelves．The need for electronic reading devices is likely to grow as more people worried about the billions of tons of paper used for printed material． Many believe the time will come when devices like the Sony reader are as common as printed newspapers and magazines today．

高三英语单项填空简单题查看答案及解析

“At almost any given age，most of us are getting better at some things and worse at others，”Joshua Hartshorne，an MIT cognitive(认知的)science researcher and the lead author of a study looking at how intelligence changes as we age，told Business Insider.His team quizzed thousands of people aged 10—90 on their ability to do things like remembering lists of words，recognizing faces，learning names，and doing math.Their results suggest that no matter your age，there’s almost always a new peak on the horizon.

The human brain has a remarkable capacity to recognize and identify faces，and scientists are just beginning to learn why.On average，we know that our ability to learn and remember new faces appears to peak shortly after our 30th birthday.

Having trouble focusing? The study suggests that our ability to maintain attention improves with age，reaching its peak around age 43.While younger adults may excel in the speed and flexibility of information processing，adults approaching their mid-years may have the greatest capacity to remain focused.

Dating is tough.One of the reasons could be that we’re generally bad at reading other people’s emotions until we reach our late 40s.That’s according to one component of Hartshorne’s study，which involved showing thousands of people images of faces cropped tightly around the eye area.Participants were asked to describe the emotion the person in the photo was feeling.Performance peaked for people aged around 48.

Many people believe that their math skills decline after they leave school and stop practicing arithmetic.But the next time you try to split up a check，keep this in mind:your ability to do basic subtraction and division doesn’t reach its apex until your 50th birthday.

Ever wonder why you always lose at Scrabble? Good news:Your best days may be ahead.According to people’s scores on multiple—choice vocabulary tests，most of us don’t reach our peak wordsmithing abilities until we’re in our late 60s or early 70s.

1.What did the scientists mainly test during the research?

A. Communication ability. B. Athletic ability.

C. Intelligence ability. D. Reading ability.

2.What does the underlined word“apex”in paragraph 5 mean?

A. Destination. B. Top. C. Goal. D. Minimum.

3.Who is most likely to succeed according to the text?

A. Lucy，72，trying to win at Scrabble.

B. Tom，26，trying to identify strangers’ faces.

C. Jack，48，trying to focus his attention for a long time.

D. Lily，43，trying to read the emotions in different eyes.

4.What does Hartshorne’s study mainly tell us?

A. There is no end to learning.

B. Constant dropping wears away the stone.

C. Genius is nothing but labor and diligence.

D. A foot may prove short while an inch may prove long.
