Thousands of villages in the developing world have no telephones. They have no money to build telephone systems. A new kind of technology may help change this situation. I t reduces the cost of building and using telephone systems.
Traditional systems use wires to carry electrical signals from one telephone to another. The wires often cost much more than telephones. The new system is based on radio communication. Each telephone sends and receives signals through the air, but not through the wires. This reduces the cost greatly. The radio telephone gets their power from the sun.
Each is connected to a solar equipment that changes the sun’s energy into electricity. A battery stores the electricity until someone needs to make or receive a call. The telephone turns off by itself if the level of power in the battery falls too low. This prevents damage to the system. Each radio telephone is connected to a computer microprocessor. It rewards how many calls are sent and received. It controls the power supply.
The technology needs more study, but its new use of radio equipment sun power and computers may help start telephone ringing in the other parts of the world.

Because earthquakes happen without warning, it’s important to take measures now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.

  1. Water

  A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.

  2. Food

  It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.

  3. Torch(手电筒) and spare batteries (电池)

  Keep a torch beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄露).Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.

  4. Clothes

  If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.

1.Why should people prepare themselves for an earthquake?

   A. Because earthquakes can be known before they happen.

   B. Because earthquakes take place without warning.

   C. Because earthquakes usually take place in the neighborhood.

   D. Because it’s people’s daily work to prepare the earthquakes.

2.You should prepare all of the following except ______.

   A. powdered milk    B. fresh vegetables   C. dried fruits   D. canned juices

3.According to the article we know that ______.

   A. we need to prepare some supplies only at home

   B. a telephone is the most important prepared thing

   C. after earthquakes you’d better use torch first but not matches

   D. clothes are used to protect your head

4.If you live in a cold place, you should prepare _______.

    A. some warm clothes and bedding supplies       B. some hot water

C. some batteries                               D. some torches
