CATV is short for "community antenna (公用天线) television". But "cable television" is the name most
people like to use. Cable television can help people receive TV programs that they can not get with their ordinary
(常规) antenna. 
      Television signals (信号) travel in straight lines in all directions. Signals from a TV station move towards the
horizon (地平线) and then go into space. If people live only a few miles from a TV station, they may get a good
picture on their televisions. But if they live more than 50 miles from a station, they may not get good pictures.
      CATV began in 1948. People in places far from TV stations had to pay for it. A community antenna was
usually placed on a hill, a mountain or on a high tower. The antenna can receive TV signals and send them into
a small local station (当地电视台).
      Today, cable television is used in more and more areas. It is even used in many classrooms all over the
country.

     Helping your children to read and write at home will improve their skills and confidence-it will also make
them get ready for learning in the classroom environment. 
    _______ are needed by every child in every subject in every year of their life in or outside school. Students
who improve their reading and writing skills will increase their vocabulary and their ability (能力) to use the
English language correctly. As parents, you can play an important role in improving your children's literacy
(读写能力). You can make a difference by listening, asking questions, giving information, and reading with
your children outside school hours.
     Here are 8 tips on how to help your children to read and write:
     ☆ having everyday conversations with your children
     ☆ trying to ask more "wh-" questions instead of easy "yes" or "no" questions
     ☆ encouraging your children to talk about events you don't know
     ☆ reading to your children each night
     ☆ listening to your children read
     ☆ teaching your children how to use dictionaries
     ☆ talking about your children's writings
     ☆ practicing filling in forms, writing letters, sending cards or emails
     You can also encourage your children to join the Reading Challenge Club and discuss the books they
are reading together. In the club, children must read 15 books from the Challenge book list and 5 more
books chosen by themselves. There are over 1,000 books on the list. The reading must be done in one year.
What's more, it is a wonderful way to help your children to write. For example, you can encourage them to
write diaries or book reviews. Remember to make positive comments as much as possible.

     We have always been interested in the moon. 2000 years ago people already knew it moved around the
earth and where it would be in the sky at different times of the year. At that time, everything about the moon
was learned by watching it carefully in the sky. 　　
     When scientists could use telescopes to study the moon more closely, their ideas began to change. They
could see the moon was made of rocks. Most scientists thought moon rocks would be different from those
on Earth. This was because they believed the moon had once been a planet that had been caught in the earth's
gravity (引力) millions of years earlier. 　　
     In 1969 moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found
that, except for water, the moon and the earth were made of the same things. Once again new ideas were
needed for this new information. 　　
     After years of study, most scientists now think that the moon was once part of Earth. They believe very
early in its history, maybe 4 million years ago, something about the size of Mars hit Earth. This sent billions
of rocks into space around our planet. These rocks slowly joined together and after many years became the
moon. In the future, even though our ideas about the moon may change again, we will still be interested in it.
