  A new study suggests that very young children who watch a lot of television may have attention problems later in school.

  Children with attention problems cannot sit still or control their actions.They talk too much, lose things, forget easily and are not able to finish tasks.

  People with attention problems may suffer a condition known as Attention Deficit Disorder(A.D.D.).Experts say the cause of A.D.D.involves chemicals in the brain.Teachers say many children in the United States are showing signs of disorder.Some education researchers have been saying for years that watching television at a very young age could change the normal development of the brain.For example, they say that children who watch a lot of television are not able to sit and read for an extended period of time.

  The new study tested the idea that television watching by very young children is linked to attention problems by the age of seven.It involved more than 1300 children.There were two groups of children, ages one and three.Researchers at Children’s Hospital in Seattle, Washington reported the results in the publication Pediatrics(儿科).They asked the parents how often the children watched television.The parents also described their children’s actions at the age of seven using a method that can tell if someone suffers Attention Deficit Disorder.

  The children who watched a lot of television at an early age were most likely to have attention problems.Every hour of watching television increased the chances of having attention problems by about ten percent.

  The researchers say that all the children with attention problems might not have A.D.D.But they still could face major learning problems in school.The findings support advice by a group of doctors that children under the age of two should not watch television.

  One of the researchers says there are other reasons why children should not watch television.Earlier studies have linked it with children becoming too fat and too aggressive(好斗的).Other experts say the new study is important, but more work needs to be done to confirm the findings and better explain the cause and effect.

  本文描述的是儿童看电视对他们以后的一些消极的影响。孩子过早地看电视或者看电视过多都会导致孩子记忆力难以集中,多动,好斗,容易忘事等等。

  So far, scientists have named about 1.8 million living species(物种), and that’s just a small part of what probably exists on Earth.With so many plants, animals, fungi, and other organisms covering the planet, it can be tough to figure out what type of spider is crawling up your leg or what kind of bird just flew by.

  A soon-to-be-launched Website might help.An international team of researchers has announced the creation of a Web-based Encyclopedia of Life(EOL).The project aims to catalogue every species on Earth in a single, easy-to-use reference guide.

  To get the encyclopedia started, the creators will use information from scientific databases that already exist.And eventually, in special sections of the site, nonscientists with specialized knowledge will join.Gardeners, for example, will be able to record the dates that their flowers first bloom each year.Bird-watchers will be able to input which birds they’ve seen and where.The technology for this kind of tool has only recently become available.

  As the EOL develops, you might find it useful for school projects.The site will have special pages for kids who are studying ecosystems in their neighborhoods.To make sure the encyclopedia is accurate, scientists will review much of the information added to it.People who visit the site will be able to choose to skip pages that haven’t been reviewed.

  Another convenient characteristic of the EOL is that you’ll be able to pick the level of detail you see to match your interests, age, and current knowledge.If you wanted to learn about polar bears for a science class report, for example, you could use the“novice”setting to get basic information about the animals.On the“expert”setting, on the other hand.you could get much more detailed information about the history, literature, and exploration of polar bears.

  It now takes years for scientists to collect all the data they need to describe and analyze species.The creators of the Encyclopedia of Life hope that their new tool will speed that process.

  Keep an eye on www.eol.org.Pages will begin to go up sometime next year, and you might find them useful for your school reports.The EOL team might have the basics for all 1.8 million entries online as early as 2017.Someday, you might add your own notes.
