Unit 91 In popular culture, the term UFO–or unidentified flying object–refers to a suspected alien spacecraft, although its definition encompasses any unexplained aerial phenomena. UFO sightings have been reported throughout recorded history and in various parts of the world, raising questions about life on other planets and whether extraterrestrials have visited Earth. They became a major subject of interest–and the inspiration behind numerous films and books–following the development of rocketry after World War II.通俗地说，所谓 UFO--或者不明飞行物--指疑似外星人的飞船，不过它的定义也包括无法解释的空中现象。

在全世界各地不同时期都有 UFO 目击的报告，引起人们关于外星生命以及地外生命是否访问过地球的争论。

在二战后火箭技术的发展下，它们成了人们感兴趣的一大主题--也是数不清的电影和书籍背后的灵感来源。

Flying Saucers2 The first well-known UFO sighting occurred in 1947, when businessman Kenneth Arnold claimed to see a group of nine high-speed objects near Mount Rainier in Washington while flying his small plane. Arnold estimated the speed of the crescent-shaped objects as several thousand miles per hour and said they moved “like saucers skipping on water.” In the newspaper report that followed, it was mistakenly stated that the objects were saucer-shaped, hence the term flying saucer.飞碟首个著名的飞碟目击事件发生在 1947 年，一个叫 Kenneth Arnold 的商人声称他在华盛顿的雷尼尔山附近玩小型飞机模型时看到了一组9个高速移动的物体。

科技英语阅读与翻译全文Humanitarian Aid in SpaceSpace exploration technology will benefit developing countries in a variety of ways. Whether it's information about climate change or communication technologies that give remote areas access to the world outside, space science can come to the aid of vulnerable people in many countries.For the past two decades, Japan Aerospace Exploration Agency (JAXA) has been sending humanitarian aid dispatched from its space platform. This ambitious project has proved successful, and it’s been praised for its achievements in various aspects.The two strategic areas set forth for JAXA’s humanitarian aid effort are science and education. JAXA’s donations of books and puzzle sets are enabling elementary and junior high school kids in India to study science and math. There are plans to utilize remote sensing data to map out natural resources in Nepalese countryside and expand education related to environmental issues in Vietnam. In addition the agency is sending educational videos to the island nation of Palau tobetter understand their own local wildlife.JAXA is considered to be a pioneer in this area since the launch of their humanitarian aid initiative in 1997. The organization strives to make use of space applications for social welfare and reduce disparities in the world through a number of practical endeavors. The effort currently has a global reach, with projects taking place in seven continent, from Latin America to Africa.JAXA’s humanitarian aid programs will continue to grow with better technology and increased resources. The ongoing work reinforces the concept that space science and technology have the potential to contribute to enhancing the lives of people on Earth.人道主义援助在太空太空探索技术将在各个方面受益于发展中国家。

Monograph1、What is a Monograph?什么是专著？A monograph is a specialized scientific book.一本专著是一本专业的科学书籍。

As learned treatises on clearly defined topics, which may be infra-, inter-, or cross- disciplinary, monographs generally are written by specialists for the benefit of other specialists.和有infra-, inter-, or cross规律，明确界定主题的学术论文一样，专著一般是专家为了其他专家的利益而写的。

Although usually regarded as a component of the review literature of science, monographs are works that demand the highest standards of scholarship.尽管通常被认为是科学综述文献的一个组成部分，专著是要求最高学术标准的作品。

Their preparation calls for exceptional breadth and depth of knowledge on the part of their authors, who, interalia, must be able to collect, collate, analyze, integrate, and synthesize all relevant contributions to the archival literature of the scientific and engineering journals and to add original material as required.就能够收集、核对、分析、集成体，综合所有能用的上的科学和工程学术期刊的档案文献和根据需要加入的一些原始资料的作者而言，专著的起草要求知识异常的深度和广度。

科技英语阅读1-9单元译文：Unit 1罗素悖论的提出是基于这样的一个事例：设想有这样一群理发师，他们只给不给自己理发的人理发。

假设其中一个理发师符合上述的条件，不给自己理发；然而按照要求，他必须要给自己理发。

但是在这个集合中没有人会给自己理发。

（如果这样的话，这个理发师必定是给别人理发还要给自己理发）1901年，伯特兰·罗素悖论的发现打击了他其中的一个数学家同事。

在19世纪后期，弗雷格尝试发展一个基本原理以便数学上能使用符号逻辑。

他确立了形式表达式（如：x =2）和数学特性（如偶数）之间的联系。

按照弗雷格理论的发展，我们能自由的用一个特性去定义更多更深远的特性。

1903年，发表在《数学原理》上的罗素悖论从根本上揭示了弗雷格这种集合系统的局限性。

就现在而言，这种类型的集合系统能很好的用俗称集的结构式来描述。

例如，我们可以用 x代表整数，通过n 来表示并且n大于3小于7，来表示4，5,6这样一个集合。

这种集合的书写形势就是：x={n：n是整数，3<n<7}。

集合中的对象并不一定是数字。

我们也可让y={x：x是美国的一个男性居民}。

表面上看，似乎任何一个关于x的描述都有一个符合要求的空间。

但是，罗素（和策梅洛一起）发现x={a：a不再a中}导致一个矛盾，就像对一群理发师的描述一样。

x它本身是在x的集合中吗？否定的答案导致了矛盾的出现。

当罗素发现了悖论，弗雷格立即就发现悖论对他的理论有致命的打击。

尽管这样，他还不能解决这个问题,并且上世纪有很多的尝试，去解决这个问题（但没有成功）。

罗素自己对这个悖论的回答促进了类型理论的形成。

他解释说，悖论的问题在于我们混淆了数集和数集的集合。

所以，罗素介绍了对象的分级系统：数、数集、数集的集合等等。

这个系统为形式化数学的形成奠定了基础，至今它还应用于哲学研究和计算机科学分支。

策梅洛对于罗素悖论的解决方法用新的公理：对于任意公式A（x）和任意集合b，都会有一个集合满足y={x：x既在b中又满足A（x）}取代了以前的公理：对于任意公式A（x），都会有一个集合满足y={x：x满足A（x）}。
