Passage FourMost 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 conversationsB. realize that they can communicate with each otherC. realize that they can make speechesD. could understand their conversations

共用题干第三篇on the Trail of the Honey BadgerOn a recent field trip to the Kalahari Desert,a team of researchers learnt a lot more about honey badgers(灌).The team employed a local wildlife expert,Kitso Khama,to help them locate and follow the badgers across the desert.Their main aim was to study the badgers' movements and behaviour as discreetly (谨慎地)as possible,without frightening them away or causing them to change their natural behaviour. They also planned to trap a few and study them close up before releasing them. In view of the animal's repu-tation,this was something that even Khama was reluctant to do."The problem with honey badgers is they are naturally curious animals,especially when they see some- thing new,"he says."That,combined with their unpredictable nature,can be a dangerous mixture.If they sense you have food,for example,they won't be shy about coming right up to you for something to eat. They're actually quite sociable creatures around humans,but as soon as they feel they might be in danger, they can become extremely vicious(凶恶的).Fortunately this is rare , but it does happen."The research confirmed many things that were already known.As expected,honey badgers ate any creatures they could catch and kill.Even poisonous snakes,feared and avoided by most other animals,werenot safe from them.The researchers were surprised,however,by the animal's fondness for local melons, probably because of their high water content. Previously researchers thought that the animal got all of its liquid requirements from its prey(猎物).The team also learnt that,contrary to previous research findings, the badgers occasionally formed loose family groups.They were also able to confirm certain results from pre-vious research,including the fact that female badgers never socialised with each other.Following some of the male badgers was a challenge,since they can cover large distances in a short space of time.Some hunting territories cover more than 500 square kilometres.Although they seem happy to share these territories with other males,there are occasional fights over an important food source,and male badgers can be as aggressive towards each other as they are towards other species.As the badgers became accustomed to the presence of people,it gave the team the chance to get up close to them without being the subject of the animal's curiosity一or their sudden aggression.The badgers' eating patterns,which had been disrupted,returned to normal.It also allowed the team to observe more closely some of the other creatures that form working associations with the honey badger,as these seemed to adopt the badgers'relaxed attitude when near humans.What happened when honey badgers got used to humans around them?A:They became less aggressive towards other creatures.B:They started eating more.C:Other animals started working with them.D:They lost interest in people.

You have been badly injured in a car accident.It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident.However,special care must be taken in selecting new blood for you.If the blood is too different from your own,the transfusion could kill you.There are four basic types of blood;A,B,AB and O.A simple test can indicate a person's blood type.Everybody is born with one of these four types of blood.Blood type,like hair color and height,is inherited from parents.Because of substances contained in each type,the four groups must be trans fused carefully.Basically,A and B cannot be mixed.A and B cannot receive AB,but AB may receive A or B.O can give to any other group,hence it is often called the universal donor.For the opposite reason,AB sometimes called the universal recipient.However,because so many reactions can occur in transfusions,patients usually receive only salt or plasma until their blood can be matched as exactly as possible in the blood bank of a hospital.In this way,it is possible to avoid any bad reactions to the transfusion.There is a relationship between your blood type and your nationality.Among Europeans and people of European ancestry,about 42 percent have type A while 45 percent have type O.The rarest is type AB.Other races have different percentages.For example,some American Indian groups have nearly 100 percent type O.The word“hence”in line 10 means__.A.alwaysB.oftenC.thereforeD.seldom

However, special care must be taken in l new blood for you. If the blood is too different from your own, the transfusion could kill you.  There are four basic types of blood:A, B, AB, and O. A simple test can 2 a person’s blood type, which, like hair color and height, is 3 from parents.  Because of substances contained in each type, the four groups must be transfused 4 . Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group;hence, it is often called the universal 5 . For the opposite reason. AB is sometimes called the universal 6 . However, because so many reactions can occur in transfusions, patients usually receive only salt or plasma. until their blood can be 7 as exactly as possible in the blood bank of a hospital. In this way. it is possible to 8 any bad reactions to the transfusion.  There is a relationship between your blood type and your 9 .
