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

Questions are based on the following passage．

Children do not think the way adults do．For most of the first year of life， if something is out of sight， it"s out of mind．If you cover a baby"s（36）toy with a piece of cloth， the baby thinks the toyhas disappeared and stops looking for it．A 4-year-old may（37）that a sister has more fruit juicewhen it is only the shapes of the glasses that differ， not the（38）of juice．

Yet children are smart in their own way．Like good little scientists， children are always testing their child-sized（39）about how things work．When your child throws her spoon on the floor for the sixth time as you try to feed her， and you say， "That"s enough! I will not pick up your spoon again!"

the child will（40）test your claim．Are you serious? Are you angry? What will happen if she throws the spoon again? She is not doing this to drive you（41）; rather， she is learning that her desires and yours can differ， and that sometimes those（42 ）are important and sometimes they are not．

How and why does children"s thinking change? In the 1920s， Swiss psychologist Jean Piaget proposed that children"s cognitive （认知的） abilities unfold（43）， like the blooming of a flower，almost independent of what else is（44）in their lives．Although many of his specific conclusions havebeen（45）or modified over the years， his ideas inspired thousands of studies by investigators all over the world．
