Scientists in the UK have announced that the piranhafish"s reputation 21 a fearsome 22 may well not be deserved. The fish， which is found in the Amazon in Brazil， have been 23 as deadly carnivores（食肉动物 ） that work in shoals to overwhelm their prey and strip it of its flesh in seconds.

However， experts 24 St Andrews University say that piranhas are omnivores（杂食动物） that mainly eat fish， plants and insects. They form. big groups not to hunt but to defend 25 against other predators， according to the team.

"Previously it was thought piranhas shoaled as it 26 them to form. a cooperative hunting group，" said Professor Anne Magurran. " 27， we have found that it is primarily a defensive behavior. "

Piranhas can be attacked by animals 28 dolphins， caimans and large fish， so forming a shoal is a good way of 29 being killed. Piranhas of 30 age stay in the middle of the group for 31 and the 32 of the shoal differs according to the level of 33 When the water level is 34， the fish form. small groups as there is space to escape， but when the water level drops， they form. large groups as protection 35 predators.

The Moon, which has undergone a distinct and complex geological history, presents a

striking appearance. The moon may be divided into two major terrains: the maria (dark

lowlands) and the terrace(bright highlands). The contrast in the reflectivity (the capability

of reflecting light) of these two terrains suggested to many early observers that the two

(5) terrains might have different compositions, and this supposition was confirmed by missions to

the Moon such as Surveyor and Apollo. One of the most obvious differences

between the terrains is the smoothness of the maria in contrast to the roughness of the

highlands. This roughness is mostly caused by the abundance of craters; the highlands are

completely covered by large craters(greater than 40-50 km in diameter), while the craters

(10) of the maria tend to be much smaller. It is now known that the vast majority of the Moon's

craters were formed by the impact of solid bodies with the lunar surface.

Most of the near side of the Moon was thoroughly mapped and studied from telescopic

pictures years before the age of space exploration. Earth-based telescopes can resolve

objects as small as a few hundred meters on the lunar surface. Close observation of

(15) craters, combined with the way the Moon diffusely reflects sunlight, led to the

understanding that the Moon is covered by a surface layer, or regolith, that overlies the

solid rock of the Moon. Telescopic images permitted the cataloging of a bewildering array

of land forms. Craters were studied for clues to their origin; the large circular maria were

(20) seen. Strange, sinuous features were observed in the maria. Although various land forms

were catalogued, the majority of astronomers' attention was fixed on craters and their

origins.

Astronomers have known for a fairly long time that the shape of craters changes as

they increase in size. Small craters with diameters of less than 10-15 km have relatively

(25) simple shapes. They have rim crests that are elevated above the surrounding terrain,

smooth, bowl-shaped interiors, and depths that are about one-fifth to one-sixth their diameters.

The complexity of shape increases for larger craters.

What does the passage mainly discuss？

A．What astronomers learned from the Surveyor and Apollo space missions

B．Characteristics of the major terrains of the Moon

C．The origin of the Moon's craters

D．Techniques used to catalogue the Moon's land forms

art of it, they may cheer themselves by remembering that life need not resemble closely the life that exists on Earth. Mars looks like the only planet where life like ours could exist, and even this is doubtful. But there may be other kinds of life based on other kinds of chemistry, and they may multiply on Venus or Jupiter. At least we cannot prove at present that they do not.

Even more interesting is the possibility that life on their planets may be in a more advanced stage of evolution. Present-day man is in a peculiar and probably temporary stage. His individual units retain a strong sense of personality. They are, in fact, still capable under favorable circumstances of leading individual lives. But man's societies are already sufficiently developed to have enormously more power and effectiveness

than the individuals have.

It is not likely that this transitional situation will continue very long on the evolutionary time scale. Fifty thousand year's from now man's societies may have become so close-knit that the individuals retain no sense of separate personality. Then little distinction will remain between the organic parts of the multiple organism and the inorganic parts (machines) that have been constructed by it. A million years further on man and his machines may have merged as closely as the muscles of the human body and nerve cells that set them in motion.

The explorers of space should be prepared for some' such situation. If they arrive on a foreign planet that has reached an advanced stage (and this is by no means impossible), they may find it being inhabited by a single large organism composed of many closely cooperating units.

The units may be "secondary"-machines created millions of years ago by a previous form. of life and given the will and ability to survive and reproduce. They may be built entirely of metals and other durable materials. If this is the case, they may be much more tolerant of their environment, multiplying under conditions that would destroy immediately any organism made of carbon compounds and dependent on the familiar car bon cycle.

Such creatures might be relics of a past age, many millions of years ago, when their planet was favorable to the origin of life, or they might be immigrants from a favored planet.

Humans on Earth today are characterized by______.

A．their existence as free and separate beings

B．their capability of living under favorable conditions

C．their great power and effectiveness

D．their strong desire for living in a close-knit society

urney leading to retirement. The new older worker is developing a third stage of working life, the period beyond the traditional retirement age and final .disengagement from the work role.

The third age of life has been associated with choice, personal fulfillment, and liberation. Workplaces are searching for ways to increase productivity, older workers are asking for in: creased career development opportunities and yet are still neglected by most workplaces. We are going to discuss some of the misconceptions about older workers and the reality of a more active and involved older adult workforce.

There appears to be considerable variation in the concept of 'older worker' as defined by age alone. The term 'older worker' extends from 40 to 75 years of age. The concept of older worker encompasses different ages depending on the purpose of the organization as well as the needs of the worker. Age alone may not be a defining characteristic of an older worker. Per, haps becoming an older worker is more situational than chronological(按年代顺序排列的).

Retirement for future older workers is becoming an outdated notion. From a societal perspective, the issue has changed from assisting older workers to retire and use leisure time to retaining and recruiting older workers. Recruitment and retention will become a key policy issue to satisfy the increasing demands for productivity, worker shortages, and retaining corporate knowledge. From a national policy perspective, increasing work life eases the social security burden, and requires programs for reemployment and continued employment of older workers. In the future, retirement will be interspersed with older workers cycling in and out of periods of active employment. Work will become an integral part of living. In the future, baby boomers may not be able to retire due to frequent job changes, underemployment, and not having acquired a consistent retirement package such as one might earn over a working life in a one-career job.

Organizations are experiencing an attitudinal shift, seeing the value and importance of training older workers. During the past decade, advocates concentrated on convincing employers that older workers are capable of learning. Today, advocates are demonstrating that with training to maintain, enhance, or update skills, older workers are contributing to organizational productivity and may even surpass younger workers in reliability and consistency. By implementing ecological changes in training and workplace design, the productivity of older adults can be enhanced. Older adults are now viewed as assets in terms of work ethic, reliability, accuracy, and stability. However, myths about aging still arc present and some workplace supervisors(监督者)still are unsure that hiring older workers is a sound investment. Older Workers are also asking more of the workplace and asserting their right to make decisions to return or remain in the workplace based on availability of training, need to be engaged, or desire to develop a second career. Older workers are becoming entrepreneurs, beginning new businesses and hiring other older workers. Managers are advised to create meaningful work and to consider the role of work in the lifestyle. of an older adult.

There is a trend toward providing increasing career development opportunities for older workers. Career development programs for older adults are a worthwhile societal investment. Community colleges and community agencies are taking a role in providing advocacy for employment, counseling, and development of new workplace skills. Partnerships among community agencies, educational institutions, and employers are suggested as an integrated approach to retraining and for providing reentry for older workers. The continued skill development of older workers can provide workplaces wi
