The bedroom door opened and a light went on, signaling an end to nap time．The toddle（初学走路的婴儿）, sleepy-eyed, clambered to a swinging stand in his crib．He smiled, reached out to his father, and uttered what is fast becoming the cry of his generation: "iPhone!"

         Just as adults have a hard time putting down their iPhones, so the device is now the Toy of Choice for many 1-, 2- and 3-year-olds．The phenomenon is attracting the attention and concern of some childhood development specialists．

Natasha Sykes, a mother of two in Atlanta, remembers the first time her daughter, Kelsey, now 3 but then barely 2 years old, held her husband's iPhone．"She pressed the button and it lit up．I just remember her eyes．It was like 'Whoa!' "The parents were charmed by their daughter's fascination．But then, said Ms．Sykes （herself a Black Berry user）, "She got serious about the phone．" Kelsey would ask for it．Then she'd cry for it．"It was like she'd always want the phone," Ms．Sykes said．

Apple, the iPhone's designer and manufacturer, has built its success on machines so user-friendly that even technologically blinded adults can figure out how to work them, so it makes sense that sophisticated children would follow．Tap a picture on the screen and something happens．What could be more fun?

The sleepy-eyed toddler who called for the iPhone is one of hundreds of iPhone-loving toddlers whose parents are often proud of their offspring's ability to slide fat fingers across the gadget's screen and pull up photographs of their choice．

Many iPhone apps on the market are aimed directly at preschoolers, many of them labeled "educational," such as Toddler Teasers: Shapes, which asks the child to tap a circle or square or triangle; and Pocket Zoo, which streams live video of animals at zoos around the world．

Along with fears about dropping and damage, however, many parents sharing iPhones with their young ones feel guilty．They wonder whether it is indeed an educational tool, or a passive amusement like television．The American Academy of Pediatrics is continually reassessing its guidelines to address new forms of "screen time．" Dr．Gwenn Schurgin O'Keeffe, a member of the academy's council, said, "We always try to throw in the latest technology, but the cellphone industry is becoming so complex that we always come back to the table and wonder- Should we have a specific guideline for them?"

Tovah P. Klein, the director of a research center for Toddler Development worries that fixation on the iPhone screen every time a child is out with parents will limit the child's ability to experience the wider world.

As with TV in earlier generations, the world is increasingly divided into those parents who do allow iPhone use and those who don't. A recent post on UrbanBaby.com, asked if anyone had found that their child was more interested in playing with their iPhone than with real toys. The Don't mothers said on the Website: "We don't let our toddler touch our iPhones ... it takes away from creative play." "Please ... just say no. It is not too hard to distract a toddler with, say ... a book."

Kathy Hirsh-Pasek, a psychology professor who specializes in early language development, sides with the Don'ts. Research shows that children learn best through activities that help them adapt to the particular situation at hand and interacting with a screen doesn't qualify, she said.

Still, Dr. Hirsh-Pasek, struck on a recent visit to New York City by how many parents were handing over their iPhones to their little children in the subway, said she understands the impulse (冲动). "This is a magical phone," she said. "I must admit I'm addicted to this phone."

The Energy Diet

How can I lose weight when every time I go on a diet, I'm so exhausted that I can barely make it through the day? So goes the complaint of many men and women who are concerned about being overweight. What many people don't realize is that a healthful weight-loss plan can actually boost your energy. The key is to eat smart. And then combine this healthful diet with some physical activity. Here are six pointers to get you started.

1.____

Consume too few calories and you'll have less energy, and decrease the amount of calories burned. "That's because one of the ways the body protects itself from starvation is to slow down its metabolism," explains Dr. Donald Hensrud, a nutrition professor at the Mayo Clinic, in Rochester, Minn. So how many calories do you need to feel energized while also slimming down? A healthful weight-loss rate is roughly one-and-a-half pounds per week, and the calorie intake to achieve this depends on your age, weight, and activity level.

2.____

The key to keeping your energy level up when you diet is to eat balanced meals that supply all the nutrients you need. "Vitamins and minerals act like spark plugs," explains Kristine Clark, director of sports nutrition at Pennsylvania State University. "They help release the energy in nutrient-rich food." Try to follow USDA guidelines. They call for 6 to 11 servings per day from the bread, cereal, rice, and pasta group; three to five servings of vegetables; two to four of fruits; two or three of milk or cheese; two or three of meat, fish, or eggs. Avoid fried and creamy dishes, and keep consumption of sweets and desserts to a minimum.

3____

When you go for five to six hours without food, the amount of fuel in your system starts to run low, and you begin to feel tired. Therefore, says Kristine Clark, it's important to eat at regular intervals to keep your energy up. If you exercise, it's important to make sure you have "fuel in the tank" before you head for the gym. Avoid eating a large number of calories at one time, since it's harder to control your total calorie intake, making weight gain more likely.

4____

About 10% of women of childbearing age in the United States are iron deficient. Iron is essential for energy and endurance because it is a vital component of red blood cells, which carry oxygen to working muscles. "Fatigue and listlessness can be directly associated with too little iron," says Frances Berg, a licensed nutritionist in Hettinger, N.D. The best sources of iron are meat, poultry, and some fish. Other sources: fortified cereals, dried beans, dried fruits, and peas.

5____

"I don't have the energy to exercise!" say many dieters. Indeed, a 1998 survey, developed in part by the Center for Sports Medicine at Penn State, found that over 70% of respondents cited "too tired" or "lack of energy" as key reasons to skip exercising. Yet exercise is exactly what these people need. And, lastly, don't try to do too much too soon. Consider breaking your exercise into small units. Instead of trying to do 30 minutes in one chunk, accumulate exercise in short bouts （一场，一回）every day by mowing the lawn, walking to work, or climbing stairs instead of taking an elevator. It won't be long before you reap （收获）the rewards. Imagine carrying a 15-pound sack of groceries around all day. Then think about how much more energy you'd have if you put that sack down.

On the Iraq-Syria border, a pack of wild dogs circled a group of American soldiers for food. The 1 of the pack was a gray-and-white dog. The soldiers 2 him Nubs. Nubs was shaking and 3  able to stand. Marine major Brian Dennis looked closer and saw that there was a knife wound 4 his chest.

      Dennis couldn’t 5 seeing the dog suffer. He and his men immediately treated the wound, and gave Nubs oral medicine. Nubs pulled through but was still 6. The next day, the team had to leave. Ten days later, Dennis’s unit was back and so was Nubs. He was still 7, but the men fed him and played with him.

   Before long the unit once again 8 an outpost (前哨) 70 miles away. Nubs, slowly but 9 tracked them far into the trackless wasteland until the men lost 10 of him. Two days later, beyond Dennis’s 11, he saw Nubs just outside the outpost. The dog had 12 him across 70 miles of frozen desert to meet the friend who had saved his life. From then on Nubs and the men slept in the same place, and ran around in the same ruins.

   Until a(n) 13 came down from above that they should not be allowed to have pets, Dennis decided to make sure the dog 14 continue to live the good life. So he quickly 15 $4,000 from his family and friends to fly Nubs to 16.

   A month later, when Dennis and the dog were 17 in California, at first Nubs didn’t recognize the guy. 18 within seconds , the dog flew into Dennis’s arms, 19 up again and again to lick his friend’s face.

   A little care and concern in the middle of war will not save a 20 world. But small stories, like the story of a soldier and a dog, hold a promise of a harmonious world.

Farming was once the chief way of life in nearly every country. People cannot live without food, and nearly all their food comes from crops and animals raised on farms. Not many people farm for a living any more, but farming remains the most important work in the world.

    Before the nineteenth century, the typical American family lived on a small farm. They raised pigs, cattle, sheep, chickens, and planted corn, fruits, garden vegetables, and wheat. Everyone worked long and hard, but the results were often poor. Families barely harvested enough food for themselves. This situation began to change during the last half of the 1800's and it changed remarkably(明显地) in the next century.

Scientific methods and labor-saving machinery have made farming increasingly productive. The development of improved plant varieties and fertilizers has helped double and even triple the production of some major crops. More scientific animal care and animal raising have helped increase the amount of meat and products that animals produce. At the same time, the use of tractors and other modern farm equipment has sharply reduced the need for farm labor.

As farming has become less important as a way of life in the United States, it has become more important as a source which offers materials to industry. Today's successful farmers are experts not just in agriculture but also in accounting, marketing, and finance. Farms that are not run in a similar way have great difficulty surviving.

We are told in the first paragraph about ____.

A. the history of farming                       B. the importance of farming  

C. the development of farming                  D. the changes of farming

Which of the following describes American farming before the 19^th century?

A. Farmers didn’t work hard on their farms.  

B. Farmers used tractors to help them.

C. Farming was the main way of living for most people.

D. Farmers could supply materials to industry.

Crop production has increased greatly now thanks to all the following EXCEPT __.

   A. scientific methods                 B. labor- saving machinery    

C. farmers’ hard work                 D. chemical fertilizers

The passage mainly talks about_____.

   A. the advantages of American farming              B. the changes in American farming 

C. the situation of American farms                  D. how rapidly farming has developed

以下是关于这些插图的简要评论。请把评论与相关插图及提示性文字匹配起来。

1.The debate has been raging for years over the safety of, and necessity for, childhood vaccinations, which has been so much so that it is termed "The Vaccine War". The debate has only a few moments that might be inspiring to those who have been following this now familiar issue.

2.There are certainly benefits of using a star in a film. It makes the film easier to market. Stars also help sell more tickets and drive DVD sales, which are a big part of studio revenue. However, a star does not guarantee success. The simple fact is that if you pay a star a great deal of money for a film that people don't want to see, then it won't work.

3.They are barely in their twenties and are already multimillionaires. At the age when many people are looking for their first job, the youngsters of The Sunday Times Rich List are buying country estates or jetting off to their overseas homes. Daniel Radcliffe, for example, who plays Harry Potter, has a fortune of 42 million, at 20.

4.Millions of jobless Americans, who might be suffering in anxiety and lacking a sense of security, are showing up at emergency rooms of state-owned hospitals, contributing to a longer waiting time and a higher risk of cursory treatment by overworked doctors and nurses.

5.Alice Miller, a psychology expert, who died at 87 at home in Provence, France, on April 14, repositioned the family as a central place of abnormal psychological function with her theory that parental power and punishment lay at the root of nearly all human problems.
