Worldwide there are probably 70 to 100 shark attacks annually resulting in about 5 to 15 d

eaths. We say "probably" because not all shark attacks are reported: our information from Third World countries is especially poor, and in other areas efforts are sometimes made to keep attack quiet for fear of bad publicity. Historically the death rate was much higher than today, but the presence of readily available emergency services and improved medical treatment has greatly reduced the chances of deaths. Actual numbers of shark attacks certainly are going up each decade because of increasing numbers of bathers in the water, but there is no indication that there is any change in the rate of attack. By far the most common shark attacks are "hit and run". These typically occur in the surf zone where swimmers and surfers are the normal targets. The victim seldom sees its attacker and the shark does not return after a single bite or wound. In most instances, these probably are cases of mistaken identity that occur under conditions of poor water visibility and a harsh physical environment. A feeding shark in this habitat must make quick decisions and rapid movements to capture its traditional food items. Sharks might occasionally misinterpret a human for its normal prey(猎物). We suspect that, upon biting, the shark quickly realizes that the human is a foreign object, or that it is too large, and immediately releases the victim and does not return. Some of these attacks could also be related to social behaviors unrelated to feeding, such as dominance behaviors seen in many land animals. Injuries to "hit and run" victims are usually confined to relatively small cuts, often on the leg below the knee, and are seldom life-threatening.

Not all shark attacks are reported because______.

A．bad news tends to be hidden

B．it is too costly to publicize the data

C．some information is just tricky

D．no one likes to collect the statistics

第5题

Technology is the application of knowledge to production. Thanks to modern technology, we

have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expenses while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us by means of modern farming machinery and animal-breeding techniques, and has extended our life span via medical technology.

Will mankind continue to live longer and have a higher quality of life？ In large measure the answer depends on technology and our ability to use it wisely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. (82) The advancement of technology depends upon research and development, and the latest statistics show that the United States is continuing to pump billions of dollars annually into such efforts. So while we are running out of some scarce resources, we may well find technological substitutes for many of them through our research programs.

Therefore, in the final analysis the three major factors of production (land, labor, capital) are all influenced by technology. When we need new skills or techniques in machinery, people will start developing new technology to meet these needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us maintain our standard of living.

What is the best title for the passage？

A．The Definition of Technology

B．Modern Technology

C．The Application of Technology

D．The Development of Technology
