请大家帮助翻译下面的几段话
文中基本上涉及到各个领域了。请多帮助！
1、科学家还需要许多年才能研究出对付“非典”的有效办法。医生和专家认为，在现阶段，教育和预防不失为解决这一问题的最佳方法，具有立竿见影的效果。
2、“第五次网络与社会发展国际研讨会”将于2004年12月在中国南京举行。组委会将在7月1日前发出正式邀请通知。凡得到邀请的代表可以申请往返国际旅费补助。此次会议不收注册费，凡对会议主题感兴趣的各界人士均可参加此次会议，但非会议邀请者在会议期间的住宿自理。
3、互联网的迅速普及，带动了一大批像亚马孙（Amazon.com）这类基于互联网的公司的兴趣。亚马孙自成立以来一直处于亏损状态，但其股价最高时竟达到237.50美元，这使得许多老牌的绩优公司相形见绌。该如何解释这种现象呢？
4、我从贵校网站上查到你们这家世界著名实验室的资料，并注意到你们尚可接受2004年的博士后申请。我一直对约翰·史密斯研究小组的课题非常感兴趣，已在这领域发表了10篇论文（详见简历中的文章目录）。我将于2004年6月参加博士论文答辩，非常希望在拿到博士学位后能有机会加入史密斯教授的小组继续从事这方面的研究工作。
5、太空垃圾是人数自己酿成的苦酒，发射后的火箭、失控的卫星以及它们被撞毁后的碎片，都会变成这种危险的东西。根据1997年的估计，目前这种较大的碎块已经有3500多万块，而小砂似的颗粒，则可能有几十亿之多。更可怕的是，它们平均每年以10%的速度在增加着，而且大多在离地约200千米的空间乱飞。

你这到底是求助还是考人啊？！ scientists needs …… 1. It still takes many years for the scientists to develop effective treatments for SARS. Doctors as well as experts think that at present education and precaution are the best way to deal with this problem with instant effect.
2. The 5th International Conference on the Development of Network and Society will be held in Nanjing, China on December 2004. The official invitation letter will be sent by the committee before July 1st. The delegates who have the invitation letter can apply for the subsidy for the international travelling expenses. No registration fee is need. Anyone who is interested in this theme can participate, but those who don’t have the invitation letter should deal with their accommodation themselves during the conference.
3. The popularization of Internet inspires a great number of Internet based companies such as Amazon.com. Amazon has been in a deficit state since its startup. However, its highest share price reached $237.50, which threw many old-brand companies with good performance into the shade. How can wee explain this phenomenon?
4. I got the document about your world-famous laboratory on the website of your university, and noticed that the postdoctoral applications in the year of 2004 are still needed. I have been significantly interested in the projects of John Smith group, and have published 10 papers in this filed (see the paper list in my resume). I will participate the doctoral thesis defence in June 2004, so I am looking forward to have the chance to be in the professor Smith group to continue the research in this field.
5. Space junk is a kind of “bitter wine” made by human himself. It includes the launched rockets, uncontrolled satellites or their crashed pieces. According to the estimation in 1997, at present there are more than 350 million pieces of this kind of big shivers, and billions of small sand-like particles. More terribly, their number is increasing yearly by an average of 10%, and most of them fly randomly above about 200 thousand meters from the ground. 感谢楼上两位高手，基本搞定了……
