     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.
(     ) 1. Most people like using the name of "cable television".  
(     ) 2. TV signals travel in curved lines.
(     ) 3. People who live more than 50 miles from a station mustn't get any pictures at all.
(     ) 4. The antenna sends TV signals to local station.
(     ) 5. The cable television can also be used in classrooms today.

     It may seem easy to say that plants and animals are different. Any child can tell the difference between
 a tree and a dog. But those differences are far deeper than just what they look like. The cells (细胞) that
  plants are made up of are different. In other words, the cell wail of plants has something special.
    First of all, it's important to find that not all plant cells have a cell wall. Besides, there are many
 differences of a cell wall based on the kinds of plant. The following is meant to be what a plant cell wall is
 like.
     The cell wall of a plant is on the outside of the cell membrane (膜). It is usually hard and cannot be
 bent easily, but the degree of flexibility (韧性) of the cell wall is different. It is based on the special use that
  the cell has in keeping the plant alive. Cells that make up the trunk of a tree are clearly less flexible than
  cells on a leaf.
     Cell wails act in many ways. They serve to protect the plant. They provide support, as well as help in
 the movement of chemicals and wastes into and out of the cell.  More importantly, they control the water
  that goes in and out.  Plants must have good water controlling systems (系统), allowing them to keep
  water during dry seasons, and get rid of unnecessary water. Plants can't walk around to find water, so
 being able to control water is very important.
     So there you have it , what a plant cell wall is. Of course, there are many other things that are not talked
  about here. Knowing more about plant cell wails requires further study and research.

    Siri on iPhone 4S is like a person assistant. It lets you use your voice to do things on the iPhone. You
  can just talk to Siri as you talk to a person. Siri understands what you say, knows what you mean, and
 even talks back.
    Say something like "Tell my wife I'm running late." "Remind me to call the doctor. " "Any fast food
  restaurants around here?" Siri does what you say, finds the information you need, then answers you. It's
  like you're having a conversation with your assistant.
   Siri not only understands what you say,  but it's also smart enough to know what you mean. So when
 you ask, "Any fast food restaurants around here?" Siri will reply, "I found a number of restaurants near
 you." Then you can say, "Hmm. How about hambergers?" Siri remembers that you just asked about
 restaurants for something to eat, so it will look for KFC restaurants in the neighborhood. And Sift is
  active, so it will question you until it finds what you're looking for.
     When you want to do something, just ask Siri to help you do it. Siri uses almost all the built-in apps on
  iPhone 4S. It writes texts and sends email messages. It searches the web for anything you need to know.
  It plays the songs you want to hear. It gives you directions and shows you around. It makes calls, plans
  meetings, helps you remember and wakes you up. In fact, ask Siri what it can do-it even speaks for itself.
