Sharks have gained unfair reputation for being large fierce sea animals. That humanity’s unfounded fear and hatred of these ancient creatures are leading to a worldwide slaughter (大屠杀) may result in the extinction of many larger, coastal shark species. The shark is the victim of a warped (有偏见的) attitude of wildlife protection; we strive (努力) only to protect the beautiful, non-threatening parts of our environment. And, in our efforts to restore only non-threat parts of our earth, we ignore other important parts.
A perfect illustration of this attitude is the contrasting attitude towards another large sea animal, the dolphin. During the 1980s, environmentalists in the United States objected to the practice of hunting tuna (金枪鱼) in the Pacific Ocean since these nets also caught dolphins. The environmentalists generated enough political and economic pressure to prevent tuna companies from buying tuna that had been caught in drift nets. In contrast to this effort, the populations of sharks in the Pacific Ocean have decreased to the point of extinction and there has been very little effort by the same environmentalism to save this important species of wildlife in water. Sharks are among the oldest creatures on earth, having survived in the seas for more than 350 million years. They are extremely efficient animals, feeding on wounded or dying animals, thus performing an important role in nature of knocking out the weaker animals in a species. Just the fact that species such as the Great White Shark have managed to live in the oceans for so many millions of years is enough proof of their efficiency and adaptability to changing environment. It is time for humans, who may not survive another 1,000 years at the rate they are damaging the planet, to cast away their fears and begin considering the protection of sharks as creatures that may provide us with an insight into our own survival.
1. The best summary of the passage is __________.
A. sharks have such a bad reputation

Ants have a reputation for strength,organization and teamwork.But researchers have now discovered that a key secret to the success of ants is their ability to identify the importance of age in the work place.
A study of Gentral American leaf-cutter ants has shown that the younger and stronger members are give the toughest job of cutting therough the leaves they harvest.Their sharp youn teeth do this job effectively,but as they get older their teeth become relatively worn and blunt.
But rather than being retired or abandoned by the group,the ageing ants are given a new role more suyted to their physical abilities.They become carriers and teansport the leaves back to the kingdom where they are harvested for food.
The findings by researchers from the University of Oregon and the Oregong State University support previous research showin the survival of a leaf-cutter kingdom depends on the efficiency(效率）of is workers.
“Cuting leaves is hard work,”said Dr.Robert Schofield,who led the research team.“Much of the cutting is done with a V-shaped blade(刀片）between teeth on their jaws.This blade starts out as sharp as the sharpest razor blade that humans have developed.”But over rime the teeth become blunter and the cutting job slows down.The team estimated that,because of this age-related wear,a colony(蚁群)spent twice the energy cutting leaves than it would if all the ants had sharp blades.Its findings support the idea that wear and break can be significant problems for insects as well as largre animals.
Like humans,leaf-cuttre ant recognize that older members of the group can still make a worhwhile contribution to society.“This study shows an advantage of social living that we are familiar with,”said Dr.Schofield.
1.The younger and stronger ants do the toughest job because________.
| A．they can teansport the leaves effectively |
| B．they have a sharp blade to cut leaves |
| C．other members are busy with other work |
| D．they can finish the job in a better organized way |
2.The undrelined word“blunt”in the second paragraph can be replaced by________.
| A．quite loose | B．less sharp |
| C．quite fragile | D．more dirty |
3.What happens to the ants when they become old?
| A．They no longer hve work to do. |
| B．They keep doing the same work. |
| C．They have to leave and live on themselves. |
| D．They are given a new worthwhile job. |
4.It can be learned from the passage that.
| A．Dr.Schofield is the first to research leaf-cuttre ants |
| B．older ants are more powerful in carrying leaves |
| C．large animals can also suffer from some kind of wear |
| D．leaf-cutter ants are the most lever ants in the world |
5.What can be the best title for the passage?
| A．The key secret to the success of ants |
| B．The developed structure of ant colony |
| C．The most challenging job for leaf-cutter ants |
| D．No V-shaped blade,no success of ants |

Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 of sharks, whose size, behavior, and other characteristics differ widely.

Most are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, if they are wearing black wet suits.

Sharks help human lives. In addition to providing people with food, they are helping us learn how to cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.
