TEXT D
Personality is ，to large extent, inherent --A-type parents usually bring about A-type offspring. But the
environment must also have a profound effect, since if competition is improtant to the parents, it is likely tobecome a major factor lives of their children.One place where children soak up A characteristics is school, which is, by its very nature, a highly competitiveinstitution. Too many schools adopt the "win at all costs" moral standard and measure their success by sportingachievements. The current passion for making children compete against their classmates or against the clockproduces a two-layer system, in which competitive A types seem in some way better than their B-type fellows.Being too keen to win can have dangerous consequences:remember that Pheidippides ,the first marathon runner,dropped dead seconds after saying:"Rejoice, we conquer!".By far the worst form of competition in school is the disproportionate emphasis on examinations . It is a rareschool that allows pupils to concentrate on those things they do well.The merits of competition by examinationare somewhat questionable, but competition in the certain knowledge of failure is positively harmful.Obviously, it is neither practical nor desirable that all A youngsters change into 'B's. The would needs types,and schools have an important duty to try to fit a child's personality to his possible future employment. It is topmanagement. 16.According to the author, what factors contribute to the building of personality?
A. inheritance
b. inheritance, competition and environment
c. competition
d. environment
17.Which of the following statements is not true according to the author of the passage?
A.Schools usually adopt severe competitive policies.
B. Students are often divided by competition results.
C. School is place where children cultivate their characteristics.
D. The stronger desire for winning, the better.
18.The phrase "soak up" is closest in meaning to ____.
A. pull up
b. take up
c. take in
d. pull in
19.What attitude does the author hold toward examinations in schools?
A. positive
b. negative
c. doubtful
d. neutral
20.what suggestion does the author make concerning the management of schools?
A. All students be made into competitive A types.
B. A child's personality be considered in regard to his possible future job.
C. All students be changed into B characteristics.
D. Schools abolish all forms of examinations.

Writing:
The present world witnesses invention and use of various robots, some of whom even can play games with human and defeat the latter. Such being the case, many are worried that robots will surpass human beings in intelligence and enslave them, while others believe that the human mind will always be superior to machines because machines are only tools of human minds.

As Gilbert White，Darwin ， and others observed long ago， all species appear to have theinnate capacity to increase their numbers from generation to generation. The task forecologistsis to untangle the environmentaand biologicalfactorsthat hold this intrinsiccapacity for population growth in check over the long run. The great variety of dynamicbehaviorsexhibitedby differentpopulationmakes thistaskmore difficult：sompopulations remain roughly constant from year to year; others exhibit regular cycles ofabundance and scarcity; still others vary wildly， with outbreaks and crashes that arein some cases plainly correlated with the weather， and in other cases not.To impose some order on this kaleidoscopeof patterns ， one school of thought proposesdividing populations into two groups. These ecologists posit that the relatively steadypopulations havedensity-dependent growth parameters; that is， rates ofbirth ， death ，and migrationwhich depend strongly on population density. The highly varying populationshave density-independent growth parameters， with vital rates buffeted by environmentalevents ;these rates fluctuate in a way that is wholly independent of population density.This dichotomy has its uses， but it can cause problems if taken too literally. Forone thing ， no population can be driven entirely by density-independent factors all thetime. No matter how severely or unpredictably birth， death ， and migration rates may befluctuatingaround theirlong-termaverages ， ifthere were no density-dependenteffects ，the populationwould ， in the long run ， eitherincrease or decrease without bound (barringa miracle by which gains and losses canceled exactly)。 Put another way， it may be thaton average 99 percent of all deaths in a populationarise from density-independentcauses ，and only one percent from factors varying with density.The factorsmaking up the one percentmay seem unimportant， and their cause may be correspondingly hard to determine. Yet，whether recognized or not， they will usually determine the long-term average populationdensity.In order to understand the nature of theecologist ’s investigation， we may think ofthe density-dependent effectson growth parameters as the signal ecologists are trying toisolateand interpret， one that tends to make the population increase from relativelylowvalues or decrease from relatively high ones， while the density-independent effects actto produce noise in the populationdynamics.For populationsthatremain relativelyconstant ， or that oscillate around repeated cycles， the signal can be fairly easilycharacterized and its effects described， even though the causative biological mechanismmay remain unknown. For irregularly fluctuating populations， we are likely to have toofew observations to have any hope of extracting the signal from the overwhelming noise.But it now seems clear that all populationsare regulatedby a mixture of density-dependentand density-independent effects in varying proportions.
