NEW YORK （Reuters Health）--Two years after New York City declared war on artificial trans fats（人造反式脂肪酸）, nearly all city restaurants had successfully cut the fats from their menus, health officials reported Monday.

In December 2006, the city’s Board of Health decided to launch a gradual trans-fat phase-out （逐步淘汰）from all licensed eating establishments--including restaurants, school cafeterias and street vending spots. Then many cities like Washington, San Francisco and Philadelphia, reflected it actively.

By November 2008, more than 98 percent of city restaurants had stopped using artificial trans fats for cooking, frying and baking, researchers with the city’s health department report in the Annals of Internal Medicine.

Trans fats have become notorious because they not only raise so-called “bad” LDL cholesterol （胆固醇）, as the fats in animal products do, but also lower levels of so-called “good”HDL cholesterol.

While some meats and dairy products naturally contain trans fat, most trans fats in people’s diet are artificial; they are formed when manufacturers add hydrogen to vegetable oil to make it become solid. These so-called partially hydrogenated oils were main products in foods, like crackers, cookies and pastries, and widely used by restaurants in cooking, frying and baking.

When the restriction was first adopted, the researchers note, some critics claimed it was an Orwellian measure, while others worried that restaurants would have a tough time finding suitable trans-fat replacements.                                                     

However, the transition has been smooth, Angell’s team writes, declaring that trans-fat restriction “is now a largely unnoticed part of New York City life.”

Ridding the food supply of trans fats, the researchers write, could potentially improve the cholesterol levels of millions of people.

     Four out of five parents worry that their children will become addicted to Facebook, according to a study.

    Eighty percent believe social networking sites such as Facebook and Twitter have the ability to take over their children’s lives. One in three parents, meanwhile, believe the Internet has the power to ‘rewire’ brains(“改装”大脑)without a person’s knowledge and think their children are in danger from the web.

    The extraordinary findings come from a poll of 1, 000 parents carried out by the Nominet Trust, an organization that promoted Internet projects which address social disadvantages.

    However, Nominet said their findings fly in the face of neurological(神经学上的) evidence. The Trust worked with neuroscience and education expert Dr Paul Howard Jones, who analysed researches on the Internet and society. The report—The Impact of Digital Technologies on Human Well-being—concluded that there is no neurological evidence to suggest that the Internet is more effective at ‘rewiring’ our brains than other environmental influences. It also found that the Internet is a valuable learning resource and all forms of learning cause changes within the brain.

    There have been reports that the use of the Internet with its vast resources of information is changing the way people think and affecting their ability to concentrate. But Nominet said that’s scare-mongering（危言耸听）and the misinformation about the Internet use can potentially deny（否定）its benefits to people, in particular parents who are worried about the effects on their children’s development.

    The report also found that social networking sites, in themselves, are not a special source of risk to children, and are generally beneficial as they support existing friendships. In addition, playing action video games can improve some visual processes and motor response skills, while computer-based activity provides mental stimulation, and can help slow rates of cognitive decline.

John Davis doesn’t use his GPS system in his car. Instead of guiding the direction, the Delaware farmer uses it to determine where and how much fertilizer to use on the crops on his 4,000-acre family-owned farm. Technological advances like that last year helped Davis and other Ohio farmers set a record for corn product. Ohio's corn crop in 2009 totaled 546 million bushels(蒲式耳), despite a cooler and wetter than normal spring, a dry summer and a delayed, wet harvest. Davis said. “I knew it would be a good crop, but it was much better than we expected.”

A farmer can map his fields on GPS, spotting where soil turned out to be least fertile（肥沃的） and using more fertilizer the next year in those areas where corn didn’t grow as well.

Although Ohio farmers produced more corn, it was grown on less land than in the past years. Total area used for corn in Ohio was 3.35 million acres, about the same as in 2008 but down from 3.85 million acres in 2007, said Dwayne Siekman, director of the Ohio Corn Growers Association. “When you look at the total number of acres in Ohio used for corn, it’s clear that farmers are able to do more with less,” he said. “American farmers can grow five times more corn on 20 percent less land than they did in the 1930s, saying that modern farming techniques are necessary for a growing demand in the world today.” That technology includes using improved seeds that can withstand(忍受) greater temperature extremes and pests, Siekman said.

Farmers aren't the only ones who benefit. Consumers(消费者) do, too, as food costs reduce in the face of “enough supplies of corn,” said Fred Yoder, who runs a 1,500-acre corn, soybean and wheat farm in Plain City. “This is the best, highest-producing corn crop that I've raised in 30 years,” he said.

1.Most people usually use the GPS system for ______.

A. driving their cars

B. telling the position

C. mending the car

D. supplying the sunshine

2.The farmers in Ohio use GPS to ______.

A. check if the soil is fertile in some areas

B. control the rain of the place

C. water the crops if the weather is dry

D. draw the map of all the crops

3.Why did Ohio farmers produce more corn?

A. Because they expanded more land to grow corn

B. Because they turned to technological advances

C. Because they used more and more fertilizer.

D. Because they supplies themselves with more money.

4. From the passage, we can know _____.[

A. John Davis hadn’t expected a good harvest.

B. farmers grew less land than in the 1930s

C. improved seeds cost much more money

D. the output of corn in the same field is increased.

The amount of time children spend in institutional care（机构式照顾）may affect how their brains develop. That’s the conclusion of a new study carried out by researchers at the University of Wisconsin, Harvard Medical School and the University of Minnesota. The study is published in Child Development in the journal’s January/ February 2010 issue.
To learn how the lack of care and material needs that institutionalized children often experience affect brain development, the researchers looked at 132 8- and 9-year-olds. Some of them were adopted into U.S. homes after spending at least a year and three quarters of their lives in institutions in Asia, Latin America, Russia and Eastern Europe, and Africa. Others were adopted by the time they were 8 months old into U.S. homes from foster care（寄养）in Asia and Latin America; most of these children had spent no time in institutional care, while some had spent a month or two in institutions prior to foster placement. On average, the internationally adopted children had been living with their families for more than 6 years. These children were compared to a group of American children raised in their birth families.
Children adopted early from foster care didn't differ from children raised in their birth families in the United States. Children adopted from institutional care performed worse than those raised in families on tests measuring visual memory and attention, learning visual information, and impulse （冲动）control. Yet these children performed at developmentally appropriate levels on tests involving sequencing and planning.
The take-home message: Children make tremendous advances in cognitive（认知的） functioning once they reach their adoptive families, but the early impact on their brains' development is difficult to change completely.
"We identified basic learning processes that are affected by early institutionalization," notes Seth Pollak, professor of psychology and pediatrics at the University of Wisconsin, who was the study's lead author. "Policies that speed the time in which children can be removed from institutionalized care so they can develop within family contexts should be implemented to decrease the likelihood of learning problems later in children's lives."
