  CATV is a short way of saying “community antenna(社區(qū)天線)television”.But “cable television” is the term most people use.[1]________

  Television signals do not follow the curve(曲線)of the earth.[2]________ If you live only a few miles from a station, you may not get any picture at all.

  [3]________ A community antenna was usually placed on a hill, a mountain, or on a high tower.Theantenna picked up TV signals and fed them into a small local station.From the station, thick wires called cables ran out to nearby homes.Each person using the cable paid a monthly charge.

  CATV worked well, and soon new uses were found for it.Local stations could feed programs into empty channels that were not in use.[4]________

  Today, cable television has moved into cities.It brings in extra programs that city viewers with regular antennas cannot see.[5]________

A.They travel in straight lines in all directions.Signals from a TV station move toward the horizon(地平線)and then go into space.

B.The wide use of CATV is due to the widespread of the TV set in almost every family.

C.Cable television allows viewers to receive TV programs that they cannot pick up with their regular antennas.

D.People along the cable could have local news, weather reports, and farm and school news at no extra charge.

E.CATV began in 1948.People in places far from TV stations shared the cost of putting up high antennas.

F.It is also used in many classrooms throughout the country.

G.Therefore, they could watch TV with extra charge.

Every year more and more plants and animals disappear never to be seen again.

     1    

Every day, thousands of species of animals draw closer to extinction. There are countless numbers of species which may become extinct before they are even discovered.

    2    

The problem is acid rain. Acid rain. Acid rain is a kind of air pollution.

    3    

The rain in many places isn’t natural and clean any more. It’s full of acid chemicals.     4    

But dead fish may be just the beginning of the problem. Scientists are finding other effects of acid rain.

     5    

Now scientists are also beginning to study the effects of acid rain on larger animals. For example, they believe that some deer in Poland are less healthy because of acid rain. If deer are hurt by the rain, what about people? This is the question many people are beginning to ask. No one knows the answer yet. But it is an important question for us all.

A.Seldom does it rain and there is little fresh water here for the fish. A series of development projects has destroyed the natural environment. Waste of different kinds can be seen here and there. This has caused serious problem for fish and other animals living around.

B.In some large areas trees are dying. Not just one tree here and there, but whole forests. At first scientists coundn’t understand why. There were no bugs(蟲) or diseases in these trees. The weather was not dry. But now they think that the rain was the cause. Acid rain is making the earth more acidic in these areas. Some kinds of trees cannot live in the soil that is very acidic.

C.When it falls in lakes, it changes them too. The lakes become more acidic. Acid water is like vinegar or lemon juice. It hurts when it gets in your eyes. It also kills the plants and animals that usually live in lake water. That is why the fish are dying in lakes.

D.It is caused by factories that burn coal or oil or gas. These factories send smoke high into the air. The wind often carries the smoke far from the factories.  Some of the harmful substances in the smoke may come down with the rain hundreds of miles away.

E.Strangely, it is the most intelligent but most thoughtless animal that is causing most of the problems-man. Nature is very carefully balanced and if this balance is disturbed, animals can disappear surprisingly fast.

F.In many lakes the fish are dying. Fishermen are worried because every year there are fewer fish and some lakes have no fish at all. Scientists are beginning to get worried too. What is killing

When you enter a supermarket, you see shelves full of food. You walk between the shelves. You carry a shopping basket and put your food in it. You probably hear soft, low music as you walk between the shelves. __71   .

     Maybe you go to the meat department first. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department.   72   . Maybe you will buy some of the expensive meat instead of the meat on sale.

     The department selling milk and milk products such as butter and milk powder is called the dairy department.   73   . One store has three different jars of low fat milk. One says “1 percent fat” on the jar. The second says “99 percent fat free.” The third says “LOW FAT” in big letters and “1 %” in small letters. As you can see, all the milk has the same amount of fat. The milk is all the same,    74   . Maybe the customers will buy the milk that costs the most.

       75   . The expensive meat says “Buy me!” as you walk by. The expensive jar says “Buy me! I have less fat.”

A. However, in this store the three jars of milk cost three different amounts of money.

B. If you hear fast music, you walk quickly. The supermarket plays slow music, and you walk slowly and have more time to buy things.

C. Most of the food in the supermarket is very pleasing. It all says “Buy me!” to the customers.

D. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk by all the expensive meat before you find the cheaper meat.

E. Many customers like milk that has only a little butterfat in it.
