When you think of the tremendous technological progress we have made, its amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Dont the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.

It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of the sporting spirit is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.

Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally - admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.

A.转录起始点
B.翻译起始点
C. RNA-pol结合模板DNA的部位
D.远离结构基因而能增强转录的序列
答案:C
解析:

李某和吴某签订购买宠物狗的合同,该买卖合同约定,吴某将宠物狗交付给李某后30日内,李某向吴某付款2000元。问:
(1)假如在交付日期到来之前,吴某向李某表示,由于狗已经卖给他人,要求解除合同,则吴某的主张能否成立?为什么?此时李某应如何维护自己的权益?
(2)假如在交付日期到来之前,吴某的朋友王某向吴某反映,称李某是一个骗子,劝告他不要卖狗,则吴某如何做才能维护自己的利益?为什么?
(3)假如吴某委托陈某(15岁)将狗交给李某,则该委托合同的效力应当如何认定?
(4)假如吴某将狗交给陈某后,陈某在没有将狗交付之前,狗将行人咬伤,则应当由谁承担狗咬伤他人的侵权责任?为什么?
(5)假如吴某将狗委托给陈某后,陈某将狗卖给了张某,则该买卖合同的效力应当如何确定?
(6)按照上述(5)的情形,如何才能使该买卖合同成为有效合同?
(7)假如陈某和张某的买卖合同为有效合同后,李某是否有权要求吴某承担违约责任?为什么?

答案:
解析:
(1)吴某的主张不能成立,因为根据合同法的有关规定,一方当事人在合同履行期限到来之前向另一方当事人表明不履行合同的,属于预期违约行为。对于预期违约行为,违约方不能主张合同解除权。由于吴某的行为属于预期违约,因此,李某可以根据合同法的规定,要求吴某提前承担违约责任,并有权解除合同。
(2)吴某可以行使不安抗辩权,中止自己的履行,并可以要求李某提供担保,如果李某在一定期限内没有恢复履行能力,或者没有提供适当担保,吴某可以解除合同。因为根据合同法的有关规定,李某的行为属于丧失商业信誉,而丧失商业信誉的,属于先履行方行使不安抗辩权的法定情形,故吴某可以行使不安抗辩权。
(3)该委托合同属于效力待定合同,因为根据合同法的有关规定,限制民事行为能力人订立的合同为效力待定合同。
(4)应当由吴某承担狗咬伤他人的侵权责任。因为吴某是狗的所有权人,根据合同法的有关规定,所有人或者管理人应当承担动物致人损害的民事责任,本案中,吴某是所有权人,而陈某是管理人,当然,根据合同法的相关规定,如果该委托合同为无偿,则陈某在有故意和重大过失的情况下,也应当承担民事责任,但赔偿责任应由其监护人承担。如果该委托合同为有偿,则只要陈某有过失,就应当承担民事责任。
(5)陈某和张某签订的买卖合同为效力待定会同,因为根据合同法的有关规定,无处分权人处分他人财产所签订的合同为效力待定合同,且陈某是限制民事行为能力人,限制民事行为能力人签订的合同也属于效力待定合同。
(6)由于陈某和张某签订的买卖合同既属于限制民事行为能力人订立的合同,也属于无处分权人订立的合同,因此,该合同不仅要经过有处分权人,即吴某的追认,还要经过陈某的法定代理人的追认,只有在两个追认权共同行使后,该买卖合同才能由效力待定状态转化为有效。
(7)陈某和张某的买卖合同为有效合同,这意味着吴某行使了追认权,这导致“一物二卖”,故吴某已经履行不能,因此,吴某应当向李某承担违约责任。
【精解】本案例适用的法条主要有:《合同法》第47条(限制民事行为能力人订立的合同)、第51条(无权处分行为)、第68条(不安抗辩权)、第69条(不安抗辩权的行使)、第94条第2项(预期违约导致行使法定解除权)、第108条(预期违约)、第406条(受托人的赔偿责任);《民法通则》第127条(动物致人损害的民事责任)。本案例虽然分解为七个问题,但难度较大,考生只有具备扎实的民法学功底,才能将该题答好。作答该案例题的核心是确定各类合同的效力。
