As any homemaker who has tried to keep order at the dinner table knows, there is far more to a family meal than food. Sociologist Michael Lewis has been studying 50 families to find out just how much more.
Lewis and his co-workers carried out 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 each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children." In general 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(兄弟，姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center 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 that 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 a non-event(扫兴的事).”

The Mystery of the Flashing Fireflies
During summer nights fireflies flash in the darkness. They look like bright spots of light dancing on the breeze. Catching them in a jar for a few minutes can be fun. Fireflies are not really flies, though. They are winged beetles. Scientists are using these special beetles to learn more about our world.
The reason a firefly flashed its light is to find a mate. There are around two thousand species, or kinds, of fireflies. Fireflies mate only with their own species. Each kind of firefly has its own flash pattern. It is important that fireflies recognize this pattern. That way they can find bugs of their own kind. The male firefly flies around in the sky while the female firefly stays close to the ground.
For many years, how a firefly flashes its light was a mystery. Scientists now know that a firefly’s light is a cold light. It gives off all of its power as light. It does not produce heat. A normal light bulb gives off only ten percent of its power as light. The rest of the power is wasted as heat. That is why a light bulb that has been on for a while is very hot. The firefly’s light does not feel hot like a light bulb.
Scientists have also learned that fireflies have a small built-in lantern. This special lantern is located inside a firefly’s body. To create light, a gas flows through tiny tubes. This causes the firefly to light up. A firefly can also turn its light on and off quickly. This puzzled scientists. They learned that short bursts of this gas make the firefly glow. When the gas fades, the light goes out. This process happens very quickly.
Scientists know that what they learn from fireflies will be important. Medical studies using fireflies are helping scientists fight illnesses in human beings. They have made new medicines from the chemicals used by fireflies to make light. Fireflies have also helped with new discoveries. New flashlights and flares have been made based on fireflies. These new flashlights and flares produce a cold light like a firefly. This way all the power makes the light shine. This little bug may be a pleasure to watch, but it is also an important part of our lives.
