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 important effects on the children. “In general the more question-asking the parents do, the higher the children’s 1Q 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, which needs more attention. “Middle children are invisible,” says Lewis. “When you see someone gets up from the table and walks 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 TV is on.” Lewis says, “Dinner is a non-event.”
1.Why are the parents with small families talk actively?
A. Their children are outgoing.
B. They love to community.
C. They get along well with each other.
D. They think it’s easy to control the order.
2.What is the meaning of “invisible”?
A. The middle children keep away from the dinner.
B. No one likes the middle children.
C. The middle children are quiet
D. The middle children get no attention.
3.Why are some children most likely to get up from the table during the dinner time?
A. They are full.
B. They don’t want to eat food with their families.
C. They didn’t get enough attention.
D. They want to eat alone.
4.Lewis’ research provides an answer to the question ______.
A. why TV is important in family life
B. why parents should keep good order
C. why children in small families seem to be quieter
D. why middle children seem to have more difficulties in life

A. It is important to have the right food for children.
B. It is a good idea to have the TV on during dinner.
C. Parents should talk to each of their children frequently.

As we know, it is not easy to build a satellite(卫星). Building a traditional satellite usually takes years. The costs can be as high as $250 million or more. Most members of the design teams have worked in the field for a long time. They hold advanced degrees(学历) in math, science, or engineering.
But things are changing. High costs, unusual educational needs and long start-up times are no longer an obstacle(障碍) to space exploration. The scientists have developed a new type of tiny, inexpensive earth-orbiting(轨道) satellite.
So far, college students have built and launched(发射) several cube-shaped satellites, or CubeSats. At least 15 more are ready to go. Those already in orbit take pictures, collect information and send it back to the earth, just as regular satellites do.
But you might not even have to wait until you get to college to start designing and building your own satellite. A new program called KatySat aims to get teenagers to take part in. When kids understand what satellites can do, the kinds of ideas they’ll come up with may be countless.
Education isn’t the only aim of CubeSats because these tiny, technology-filled boxes are inexpensive to build and can be put together quickly, they’re perfect for testing new technologies that might one day be used on major space tasks.
The biggest challenge now is to find ways to bring the satellites back to the earth after a year or two. Or space junk could gradually increase because CubeSats become more popular.
Nowadays, college and high school students are getting a chance to learn what it takes to explore in space. Someday—perhaps a lot sooner that you imaging—you might get to design, build and launch your own satellite. If you do, you’re sure to have fun. And you might also get crazy about science for life.
1.Building a traditional satellite __________.
A. costs $250,000
B. needs college students
C. takes quite a long time
2.Compared with the traditional ones, the new satellites __________.
A. need long start-up times
B. are cheap and small-sized
C. collect more junk in orbit
3.The underlined word “countless” in Paragraph 4 probably means “__________”.
A. 无用的 B. 无价值的 C. 无数的
4.According to the passage, which of the following is true?
A. CubeSats could possibly cause pollution in space.
B. Scientists designed CubeSats for kids to play with.
C. Students can’t design satellites without college education.
5.The purpose of the author writing the passage is __________.
A. to tell us that satellite technology can also be learned by kids
B. to show that high technology brings a big change in kids’ life
C. to tell us that kids must study hard to learn satellite technology
