[简答题]某教师在执教《相信未来》一课时，教师按照教学参考及有关参考资料的分析，分析诗歌中体现出来的作者那种在逆境中坚信未来的执着信念，树立不畏艰难的坚定信念，此时一学生在下面接嘴道：食指其实根本不相信未来。此言一出，班里顿时一片哗然。慢慢地，教室里形成了争议。这是教师课前准备时根本没想到的。但当教师发现学生对这个问题表现出来的热情时，马上决定改变教学内容与步骤，临时安排了一个小辩论，辩题是《食指相信未来》(正方)和《食指不相信未来》(反方)，先给学生三分钟时间讨论，最后通过自荐，正反双方各有三名学生进行课堂辩论。辩论时间虽然只有五分钟，但同学们从诗歌的意象、情感基调、总体风格、历史背景及食指其他诗作如《我不知道》《疯狗》以及深受其影响的北岛的诗作《回答》等进行比较，展开激辩。最后教师总结道，当年“四人帮”之首的江青在读到这首诗的时候下了如此批语：“相信未来就是否定现在。”毫无疑问食指确实是否定当时的现实的，但当时的黑暗也会令一个有理想有抱负的文学青年对未来产生疑问，这可以从他选择的那些易化易逝的意象中体会到。然而食指的可贵正在于此，虽然他对当时四人帮倒行逆施及中国的未来深感忧虑和担心，但仍然执着地坚持着中国文人的良知，因为只有让国人特别是深受摧残的知识分子相信未来，才能帮助他们顽强地生活下去，迎接光明的到来。

[简答题]"If there were none of this playing at generosity in warfare, we should never go to war, except for something worth facing certain death for, as now. Then there would not be wars because Pavel Ivanitch had insulted Mihail Ivanitch. But if there is war as now, let it be really war. And then the intensity of warfare would be something quite different. All these Westphalians and Hessians Napoleon is leading against us would not have come to fight us in Russia, and we should not have gone to war in Austria and in Prussia without knowing what for. War is not a polite recreation, but the vilest thing in life, and we ought to understand that and not play at war. We ought to accept it sternly and solemnly as a fearful necessity. It all comes to this: have done with lying, and if it’s war, then it’s war and not a game, or else warfare is simply the favourite pastime of the idle and frivolous.... The military is the most honored calling. And what is war, what is needed for success in war, wha

Prolonging Human Life
Prolonging human life has increased the size of the human population. Many people alive
today would have died of childhood diseases if they had been born 100 years ago.Because
more people live longer,there are more people around at any given time. In fact,it is a decrease in death rates,not an increase in birthrates,that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies,people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures,old people who could not keep up might be left behind to die. In times of famine,infants might be allowed to die because they could not survive if their parents starved,whereas if the parents survived they could have another child. In most contemporary societies,people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work;we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement,some-body else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people;unless they have wealth or private or government insur-ance,they must often“go on welfare” if they have a serious illness.
When older people become senile or too weak and ill to care for themselves,they create grave problems for their families. In the past and in some traditional cultures,they would be cared for at home until they died. Today,with most members of a household working or in school,there is often no one at home who can care for a sick or weak person. To meet this need,a great many nursing homes and convalescent hospitals have been built.These are of-ten profit-making organizations,although some are sponsored by religious and other nonprofit groups.While a few of these institutions are good,most of them are simply“dumping grounds”for the dying in which“care”is given by poorly paid,overworked,and under-skilled personnel.
In Paragraph 3,the phrase“this need” refers to______.
A.the need to prolong the lives of old people
B.the need to enrich the life of the retired people
C.the need to build profit-making nursing homes
D.the need to take care of a sick and weak person
