Lesson55 At Dinner Table

As any 1 knows, there is far more to a family meal than food. Sociologists have been studying families to find out just how much more.
Lewis and his co-workers 2 their study by videotaping the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with 3 and their children. But as the number of children gets larger, conversation gives way to the parent's efforts to control the loud noise they make. That can have an important effect on the children.“ 4 the more question-asking the parents do the higher the children's IQ scores,” Lewis says.“And the more children there are, the less question-asking there is.”
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings． Lewis found that in families with three or four children, dinner conversation 5 centre on the oldest child, who has the most to talk about, and the youngest, who needs the most attention “Middle children are invisible,” says Lewis.“When you see someone get up from the table and walk around during dinner, chances are it's the middle child.”
There is, however,one thing that stops all conversation and prevents anyone from having attention:“When the TV is on,” Lewis says,“dinner is non-existent.”
