Recent developments in astronomy have made is possible to detect planets in our own Milky

Way and in other galaxies. This is a major achievement because, in relative terms, planets are very small and do not emit light. Finding planets is proving hard enough, but finding life on Earth will prove infinitely more difficult. The first question to answer is whether a planet can actually support life. In our own solar system, for example, Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions, and even here it has taken more than four billion years for plant and animal life to evolve. Whether a planet can support life depends on the size and brightness of its star, that is its "sun". Imagine a star up to twenty times larger, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life.

第1题

The emergence of the European Union has been one of the defining events of the twentieth c

entury. It has changed the political, economic, and social landscapes of Western European, changed the balance of power in the world by helping Europe reassert themselves on the world stage, and helped to bring the longest uninterrupted spell of peace in Europe recorded history. Until the beginning of the twentieth century, Europe was a continent of competing powers that repeatedly fought with each other on their own soil and took their mutual hostilities to other continents in their competition to build colonial empires. The tragic costs of nationalism were finally confirmed by two world wars, fought largely on Europe and leaving the Europe powers devastated and drained. If Europe had not learned of the barbarism and futility of war in the trenches of northern France and Belgium in 1914~1918, the horrors of the period 1939~1945 finally brought home the need to cooperate and to build the kind of society that would eliminate the seeds of conflict.

A good book is often the best urn (翁) of a life enshrining the best that life could think

out; for the world of a man's life is, for the most part, but the world of his thoughts. Thus the best books are treasuries of good words, the golden thoughts, which, remembered and cherished, become our constant companions and comforters. "They are never alone," said Sir Philip Sidney, "that are accompanied by noble thoughts. "

Books introduce us into the best society ; they bring us into the presence of the greatest minds that have ever lived. We hear what they said and did; we see them as if they were really alive ; we sympathize with them, enjoy with them, grieve with them; their experience becomes ours, and we feel as if we were in a measure actors with them in the scenes which they describe.

The great and good do not die even in this world. Embalmed in books, their spirits walk abroad. The book is a living voice. It is an intellect to which one still listens.

第6题

Technology trends may push Silicon Valley back to the future. Carver Mead, a pioneer in in

tegrated circuits and a professor of computer science at the California Institute of Technology, notes there are now work stations that enable engineers to design, test and produce chips right on their desks, much the way as editor creates a newsletter on a Macintosh. As the time and cost of making a chip drop to a few days and a few hundred dollars, engineers may soon be free to let their imagination soar without being penalized by expensive failures. Mead predicts that inventors will be able to perfect powerful customized chips over a weekend at the office — spawning a new generation of garage starts-ups and giving the US a jump on its foreign rivals in getting new products to market fast. "We've got more garages with smart people. " Mead observes, "We really thrive on anarchy. "
