法国某公司(在中国境内无住所地)想要到中国投资设立服装贸易公司，经市场调查后，该公司决定与位于中国上海A区的艺云服装公司共同出资。双方签订一份中外合资经营合同后，在上海市B区设立中法合资服装公司。公司开始运营一年后，艺云公司与位于上海市C区的平安运输有限公司签订运输合同，约定将一批服装运往位于B区的公司仓库。该运输公司遂让其下属的第一运输车队负责此次运输。该运输车队责任人为李某，一年前挂靠在该公司名下。在运输车队运送的过程中，司机王某由于一时粗心大意，导致车货均翻入河中，且将赵某停放在路边的一辆桑塔纳汽车撞翻，造成赵某骨折。赵某住院期间，出具委托书全权委托北京市顺发律师事务所的刘清华律师向法院提出损害赔偿之诉。同时由于此次事故，给中法合资服装公司造成50万元的损失，生意经营惨淡。法国公司与艺云公司就损失的承担问题发生纠纷，艺云公司向上海市中级人民法院起诉，法院判决艺云公司在判决生效后一个月内向法国公司赔偿损失25万元，判决书于2004年月31日送达双方当事人。上诉期满后，双方均未上诉。10月12日，法国公司向法院申请强制执行。
问题

在赵某提出的损害赔偿之诉审理的过程中，赵某由于没有足够的经济能力支付医疗费，就向法院申请要求被告先行支付2万元以偿还所欠的医疗费，审判人员审查了赵某提交的医疗报告之后，发现赵某仍然需要长时间住院治疗，于是裁定被告向赵某支付3万元，法院的做法是否存在不合理之处，为什么

Most of the idle rich suffer unspeakable boredora as the price of their freedom from drudgery. At times they may find relief by hunting big game in Africa, but the number of such sensations is limited, especially after youth is past. 46. Accordingly more intelligent rich men work nearly as hard as if they were poor, while rich women mostly keep themselves busy with innumerable trifles of whose earth- shaking importance they are firmly persuaded.

47. Work is desirable as a preventive of boredom, for the boredom a man feels when doing necessary though uninteresting work is as nothing in comparison with the boredom he feels when having nothing to do. With this advantage of work another is associated, namely that it makes holidays much more delicious when they come. 48. Provided a man does not have to work so hard as to impair his vigor, he is likely to find far more zest in free time than an idle man could possibly find.

The second advantage of most paid work and of some unpaid work is that it gives chances of suecess and opportunities for ambition. In most work success is measured by income and while our capitalistic society continues, this is inevitable. It is only where the best work is concerned that this measure ceases to be the natural one to apply. 49. The desire that men feel to increase their income is quite as much a desire for success as for the extra comforts that a higher income can procure. However dull work may be, it becomes bearable if it is a means of buihliug up a reputation, whether in the world at large or only in one’ s own circle. Continuity of purpose is one of the most essential ingredients of happiness in the long run, and for most men this comes chiefly through their work.

50. The satisfaction of killing time and of affording some outlet, however modest, for ambition, belongs to most work, and is sufficient to make even a man whose work is dull happier on the average than a man who has no work at all. But when work is interesting, it is capable of giving satisfaction of a far higher order than mere relief from tedium. The kinds of work in which there is some interest may be arranged in a hierarchy. I shall begin with those which are only mildly interesting and end with those that are worthy to absorb the whole energies of a great man.
