The two-way radio is very important to people who live on these great Australian farms.It works much like a telephone.A person can listen to someone else talk and then give an answer.For example, people on the large farms could talk to a doctor far away.They could tell the doctor about someone who was ill, and the doctor could let them know how to look after the sick person.

As the large farms were so far from towns, the children could not go to school.Radio schools were started for them in some places.At a certain time each day, boys and girls turn on their radios and listen to teachers in cities far away.

Families on the large farms wanted to give news to their neighbors.The program "Round Robin" talks by radio was started to keep families in touch with each other.They could talk about who was going away and who was ill.The men could talk about their sheep and cows and how much money the markets would pay for them.In many ways the radio became a newspaper for the farm people of Australia.

Passage Four

Most people do not think of fishes and other sea animals as having voices, and of those who are aware of the fact that many of them can "speak", few understand that these "conversations" have significance. Actually, their talk may be as meaningful as much of our own. For example, some sea animals use their "voices" to locate their food in the ocean expanses (广阔的区域); others use their "voices" to let their fellows know of their locations; and still others, as a means of obtaining mates. Sometimes, "speaking" may even mean the difference between life and death to a sea animal. It appears in some cases that when a predator (食肉动物) approaches, the prey (被捕的动物) depends on no more than the sounds it makes to escape.

Fish sounds are important to man, also. By listening to them, he can learn a great deal about he habits of creatures that make them, the size of the School they form, the patterns of their migrations, and the nature of the environments in which they live. He can also apply this nformation to the more effective utilization of the listening spots he has set up to detect enemy submarines (潜水艇). A knowledge of fish sounds can avoid confusion and unneeded effort when a "new" sound is picked up and the sound sentry (哨兵) must decide whether or not to call an alarm.

46. Among the people who know that many sea animals have voices, few ______.

A. know the meaning of their conversations

B. realize that they can communicate with each other

C. realize that they can make speeches

D. could understand their conversations
