最近报名参加一个 Young Water Professionals的会议（1） ，组织者昨天发信让我给他们发一个我的Biography（短篇幅的传记或者个人介绍）。 因为从来没写过，也不知道这个传记和简历有什么区别，于是上网学习。发现有个几个 网站 总结的不错，介绍了 传记和简历的区别（2） ，还重点介绍了 写传记的一些要点（3） 。大家有兴趣可以去看看，然后也可以制作自己的传记。我根据这些网站提供的建议和信息，写了一个自己的传记初稿，如下： Wei Qin is a PhD student of Soil Quality Department in Wageningen University. The objectives of his research are (i) to understand water and nutrients interactions from plant to regional scale levels, (ii) to quantify the impacts of globalization and urbanization to agriculture and the environment from water and nutrients use perspectives and (iii) to explore the options to improve water and nutrients use efficiency at the regional system level. He has MSc degree from Wageningen University in International Land and Water Management and BSc from China Agricultural University in Soil and Plant Nutrition. He speaks Chinese, English and some Dutch. He is a proactive and social person. If you are interested in his research topics, please feel free to contact him via email: weiqinwur@gmail.com 第一次写，期待大家提宝贵意见，谢谢！ 相关链接： （1） http://www.internationalwaterweek.com/ （2） http://ezinearticles.com/?Bio-Vs-Resume---Whats-the-Difference?id=4098748 （3） http://writeabio.com/
There is a small corner in ScienceNetwhere generations of 80s and 90s are trying to make some change by themselves and bring their voices and ideas forwards to a broader world. There is a small corner in ScienceNet where they learn English by understanding the meaning of their lives, from inspiring movies, from kind and positivehumour, from reflections and encouragements from each other. There is a small corner in ScienceNet, which is so small but so beautiful. Now you may wonder, where exactly is thiscorner?

The Type 1 Conditional - Alternate forms （1） Future in both clauses Sometimes we use a future tense in both clauses . This is particularly common in polite requests. If you will marry me, I will love you forever. (More polite than 'If you marry me…') If you will wait for me, I will come with you. If you will help us, we will be grateful. Here will means ' is/are willing to' . In more polite requests we can use would . If you would help us, we will be extremely grateful. If you would come this way, I will take you to the theatre. Going to in result clause Going to often replaces will in the type 1 conditional. This is done to emphasize a certain result. If you skip your classes, you are going to fail. If you don't mend your ways, you are going to land in trouble. Going to can be used in the if-clause to mean 'intend to'. If you are going to skip school, you certainly won't pass your exams. Present perfect in if-clause Sometimes we use a present perfect, instead of a simple present , in the if-clause. This is to put an extra focus on the completion of an action. Compare: We will go to the movies if you have finished your work. (There is a focus on the completion of the action.) We will go to the movies if you finish your work. (There is no focus on the completion of the action.) Should in if-clause Should is sometimes used in the if-clause to imply that something is possible, but not very likely. If he should arrive , we will invite him along to dinner. (He will probably not come. But if he comes, we will invite him to dinner.) This use of should in the type 1 conditional is stronger than the type 2 conditional in which an imaginary or unreal situation is presented. Compare: If he arrives, we will invite him along to dinner. (Type 1 conditional - He is likely to come. And if he comes we will invite him to dinner.) If he arrived , we would invite him to dinner. (Type 2 conditional - I am sure he will not come.) If he studied, he would pass the exam. (Type 2 Conditional - I am sure the student will not pass.) If he studies, he will pass the exam. (Type 1 conditional - He will probably study. And if he does he will pass.) If he should study , he will pass the exam. (Type 1 conditional with should - The student will probably not study. But if he does he will pass.) Happen to/ should happen to We sometimes use happen to or should happen to in If- clauses. It suggests that something is unlikely, but if it happens, something else will happen. If they happen to come to town, we will meet them. (= They are unlikely to come. But if they come, we will meet them.) Should happen to has a similar meaning. If he should happen to get stuck in that town, he will be able to find a good hotel. Modals in result clauses We can use modals in result clauses to talk about future possibilities, permission and advice. If you finish your work, you can go out and play. You should see a doctor if you continue to feel bad. If I arrive early, I might give him a call. Provided (that), as long as Provided that and as long as can be used instead of if to say that a particular condition must be met in order for something to happen. Provided (that) he finishes his studies, he will find an excellent job. (= If he finishes his studies, he will find an excellent job.) As long as you pay off the loan, the house will be yours at the end of this year. (= If you pay off the loan, the house will be yours at the end of this year.) The Type 2 Conditional（2） Here we use a simple past in the if-clause and would + infinitive (bare form of the verb) in the result clause. If you asked, they would help you. If it rained, you would get wet. If you loved her, she would love you. If I had more money, I would buy a new car. If he studied more, he would pass the exam. If I were the President, I would lower taxes. The type 2 conditional refers to present and future situations. It is used to talk about unreal - impossible, improbable or imaginary - situations. It refers to an unlikely or hypothetical condition and its probable result. Type 1 or type 2 - What to use?Real and imaginary situations The type 1 conditional is often called the real conditional. It is used for real and possible situations. The type 2 conditional is used for unreal - impossible, improbable or imaginary - situations. Compare: If I become the President , I will give free electricity to farmers. (Said by a candidate, who may win the election - Type 1) If I win this race , I will... (- Said by the fastest runner - Type 1) If I became the President , I would give free electricity to farmers. (Said by a child - Type 2) If I won this race, I would... (- Said by the slowest runner - Type 2) Direct requests and suggestions In direct request or suggestions we use type 1 conditional. To make a request or suggestion more polite, we use type 2 conditional. Compare: I will be grateful if you lend me some money. (direct request - Type 1) It will be nice if you help me. (direct request - Type 1) It would be nice if you helped me. (less direct, more polite request - Type 2) I would be grateful if you lent me some money. (more polite request - Type 2) 原文来源： （1） http://www.perfectyourenglish.com/grammar/first-conditional-alternate.htm （2） http://www.perfectyourenglish.com/grammar/second-conditional.htm After sharing this article, I received many useful comments. Thank you very much indeed for that. To clarify some relevant points and to avoid further confusion, I have added some other information(pictures) quoted from "Advanced Grammar in Use, 2nd edition, Cambridge, 2005 "to the previous version as below:
起这个标题，自然是有标题党的嫌疑。但这绝对不是此文的本意，真正和唯一目的是想引起大家的关注，通过大家的共同努力，把科学网 真正 构建成为全球华人科学交流平台。 对于意见， 科学网一直都是从谏如流，积极接受大家的反馈意见和建议，不断改善网站的功能，尤其是服务功能，这些大家都有体会。 科学网吸引大家的原因很多，有它独特的优势，这里不再一一举例，也不是此文的重点。今天要讨论的核心问题是，科学网到底缺些什么，忽略了哪些功能，尤其是 大家（用户）需要的功能？ 这里想通过此文仅向科学网提一点建议，如下： 关于科学网博客博文的排行榜以及推荐。首先，个人并不反对任何现行的方式，对现行的方式也没有任何强烈的厌恶感或者觉得极为不便。但是，我想，科学网现在那么多用户，将来只能会更多，何不利用好这些用户，让科学网变得更好，更智能，更方便。具体的说就是，为何不提供选项，让每个点击和阅读过的用户投票推荐，从1颗星到5颗星，从而实现以后可以不光以点击率排列，也可以按用户推荐星级来进行排列（详细可参考App Store里边对应用程序的排列方式）。目前的现状，有时候会有点“被阅读”的感觉，毕竟精选的还是少数。另外还有一小点建议就是博客回复率也是一个很好的指标，这样的话，大家就可以知道，如果有问题要请教，是从博客上去联系几率大，还是直接Email或者电话更好。从技术上说，这些应该可以实现，并且相对容易。 结束语： 诚挚期盼 科学网能够接受这些建议，在技术上进行相应的调整，丰富各种功能，让科学网能够更好服务大家。我相信科学网的建立是 for us and by us。大家如果有更多的建议，也请一并提出。最后，衷心期望科学网越办越好，谢谢大家！
今天一打开 http://www.google.com/ 主页，就可以看到月食视频，对于我这种从来没看过月食的人来说，觉得还是蛮过瘾的。 关于月食，还是有不少说法的。参考中文维基里的说法是： 月食发生时，太阳、地球、月球恰好或几乎在同一条 直线 上，因此月食必定发生在 满月 的晚上（ 农历 十五、十六、或十七），但并不是每个满月时，都发生月食。每年全球至少发生两次月食。最近一次月食发生于 2011年6月16日 ，下一次月全食将发生于 2011年12月10日 。大家如果对于观看月食感兴趣，请关注发生时间。 另外， 相比于日食，月食发生的时间（月球由进入至走出地影）是十分长的，平均需时数小时，各年月食的时刻在大部分日历上均有说明。月全食时间最长可长达1小时45分，日全食最长仅能 7分31秒。2011年6月16日的月全食阶段达到1小时41分钟。但是2003年11月8日的月全蚀整个只有25分钟。 英文维基的说法是（供大家对比）： A lunar eclipse occurs when the moon passes behind the earth so that the earth blocks the sun's rays from striking the moon. This can occur only when the Sun , Earth , and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon . The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes . The most recent total lunar eclipse occurred on June 15, 2011; it was a central eclipse, visible over Europe and south America after sunset, over Africa and most of Asia, and Australia before sunrise. The previous total lunar eclipse occurred on December 21, 2010, at 08:17 UTC . Unlike a solar eclipse , which can only be viewed from a certain relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of the Earth. A lunar eclipse lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place.
