阅读理解 Many parents watch the news or other shows as children play nearby. But new research shows that even when the television is just background noise，it may be disruptive to a child’s normal development.It’s estimated that 75 percent of very young children in the United States live in homes where the television is on most of the time，even though the kids often aren’t watching it. The University of Massachusetts researchers recently studied how TV background noise might affect young children. The study looked at 50 1­，2­and 3­year­olds. Each child came to a lab with a parent and was allowed to play for an hour with various toys. For half the time，a television was on in the room，showing the adult game show as well as advertisements. During the other half hour，the TV was turned off.As expected，the children paid little attention to the adult television show，glancing at it for less than a few seconds at a time，and less than once a minute. Even so，the distraction (分心) of the background noise had a significant effect on how children at every age played. When the television was on，the children played with each toy for far shorter periods of time，and focused attention during play was also shorter compared to how they played when the TV was off.Researchers said that even though the children aren’t interested in the show，background TV affects their ability to do various types of play. The finding is important because many well­meaning parents who wouldn’t let their young children watch television may not realize that even adult programs that don’t interest children still can have an effect.“Background TV is potentially a chronic (长期的) environmental risk factor affecting most American children，” said the lead author of the study. “Parents should limit their young children’s exposure (接触).”1.We know from the passage that________.A.background TV noise has little effect on adultsB.most young children in America live in homes exposed to TV noiseC.the effect of background TV noise on children is immediateD.most parents in America wouldn’t let their children watch TV2.The underlined word “disruptive” in Paragraph 1 is closest in meaning to________.A.harmfulB.importantC.similarD.related3.In the study，the children________.A.were all 3­year­oldsB.were asked to watch adult TV showsC.played for an hour while the TV was onD.played with more than one toy4.What does the study show?A.Children pay much attention to adult TV shows.B.Children should be allowed to watch TV for kids only.C.The background TV noise affects children’s ability to focus.D.The more toys a child has，the shorter time he plays with each one.
