阅读理解 　　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。 (1) The best title for the passage is ________． [　　] A． TV and Attention Problems B． Attention and Learning C． Disadvantages of Watching TV D． Causes of Attention Deficit Disorder (2) Children with attention problems may ________． [　　] A． control their actions B． sit and read quietly C． complete tasks easily D． talk a lot in class (3) Watching TV at an early age may cause all of the following problems EXCEPT ________． [　　] A． gaining weight B． being too aggressive C． poor eyesight D． Attention Deficit Disorder (4) What can be inferred from the passage?

Answer 1

答案：1．A;2．D;3．C;4．A;
解析：

(1)	这是一道归纳概括题。做这类题时要抓住题干所给的中心词。如本题：选项A“电视与注意力的问题”，很显然是讲两者之间有什么关系。选项B“注意力与学习”；选项C“看电视的弊端”，中心词是“弊端”；选项D“注意力分散问题的起因”，中心词是“起因”。就文章整体看，本文侧重介绍了“儿童看电视对注意力所产生的不利影响”的情况。故A项为最佳选项。
(2)	这是文意理解题。从文章第二段可直接找到答案。
(3)	文章第三段指出：儿童看电视可能改变其大脑的发育，引起注意力的下降与紊乱。文章的最后一段讲了看电视能使人发胖、变得好斗等两个方面的情况。本文没有提到儿童看电视对于视力的影响。
(4)	这是一道判断推理题。根据文章最后一段的暗示可知：还需要做很多工作以确定所研究的成果和更好地解释其原因与影响。故该题答案为A。
