[font=Times New Roman][size=3]1．[/size] [size=3]Planetary scientists are not the only ones interested in the Moon.. Because it lacks an atmosphere[/size][/font][size=3][font=宋体]（大气层）[/font][font=Times New Roman],astronomers say it would be an ideal observatory[/font][font=宋体]（观测站）[/font][font=Times New Roman](infact the Moon does have an atmosphere, though it is a very thin onethat contains no more gas than the air in a three bedroom house onEarth).The Moon turns once every 27.3 days. allowing long uninterruptedviewing, And in the permanently shadowed craters near the poles, thetemperature remains constant at about -200C :ideal conditions forinfrared telescopes, In particular astronomers are interested inplacing telescopes on the far side of the Moon. because it ispermanently shielded from electromagnetic pollution from the Earth suchas radio and TV broadcasts.[/font][/size]
[size=3][font=宋体]行星科学家不是唯一对月球感兴趣的人。因为月球缺乏大气层，天文学家说它可以是一个理想的观测站（事实上月球是有大气层的，虽然它非常稀薄，它所包含的气体和一个地球上三居室的房子里的空气一样多）。月球每[/font][font=Times New Roman]27.3[/font][font=宋体]天转一圈，允许长时间的不间断的观测。在接近极地地区的长期阴影的陨石坑里，温度始终保持在[/font][font=Times New Roman]-200[/font][font=宋体]度：是放置红外线望远镜理想的条件。此外，天文学家还对把望远镜放在月球的远端感兴趣。因为那里长期的屏蔽了来自地球的像无线电和电视广播这样的电磁污染。[/font][/size]
[font=Times New Roman][size=3]2．[/size] [size=3]Onthe other hand, he acknowledges, the beauty of the evolutionaryapproach-that it emerges on its own, without anyone’s having to analyseall the complexities, is also a potential stumbling block([/size][/font][size=3][font=宋体]绊脚石[/font][font=Times New Roman])to its acceptance([/font][font=宋体]认可[/font][font=Times New Roman]),especially in applications where human life is at stake([/font][font=宋体]处于危险中[/font][font=Times New Roman]).“The software may function perfectly well, but we won’t reallyunderstand how it works,” says Jefferson. Some people might find robotslike that a little too human for comfort.[/font][/size]
[font=宋体][size=3]另一方面，他认为进化论的优点在于，它自行发展不需要其他人分析其复杂性，进化论同时也是人类认可的潜在的绊脚石。特别是在它的应用会给人类生活带来危险的时候。杰弗森说：“软件可以运做的很完美，但我们不能真正地理解它是怎样工作的”。像那样的机器人有一点太人性化以至于感到不舒服。[/size][/font]

[size=3][b][font=宋体]补充[/font][font=Times New Roman]p106[/font][/b][font=Times New Roman] Road-tollingtechnology is a top priority, especially in Britain, Several systemswill be tested as part of the electronic tolling trials starting on theM3 motorway near Basingstoke next spring. As well as debiting driversfor using the roads, the same tolling technology could be used to cuttraffic.[/font][/size]

[size=3][font=宋体]道路收费技术是最优先的，特别是在英国。在明年春天，很多系统将作为电子收费试验的一部分在靠近[/font][font=Times New Roman]Basingstoke[/font][font=宋体]的[/font][font=Times New Roman]M3[/font][font=宋体]公路上被测试。除了向使用道路的司机收费外，这个收费系统也可以用来缓解交通。[/font][/size]
[size=3][font=宋体]这个系统被交通部列入精简名单，在接下来的几个月里将使用装在跨路钢架上的微波传感器[/font][font=Times New Roman]-[/font][font=宋体]或蜂窝状的移动手机网络来探测在公路上的每一辆车，然后从装在挡风屏上的智能卡里收费。[/font][/size]

[font=Times New Roman][size=3]Will we or our descendantsall die when an extraterrestrial object comes hurtling down onto Earth?This question was brought to the fore by the enormous publicitysurrounding the collision of the fragments of the comet Shoemaker-Levy9 with Jupiter in July 1994.Even before these events ,the question hadstimulated some astronomers to propose searches to identify all largeasteroids that might hit Earth in the foreseeable future. The questionhad also stimulated developers of nuclear weapons to propose mechanismsfor deflecting such asteroids before they collide with Earth, At thebehest of the US Congress, NASA has appointed several committees toconsider detection and deflection of potentially hazardous asteroids,the most recent of which, the Shoemaker Committee, has just releasedits report, Meanwhile ,the International Astronomical Union has alsoappointed a working group to consider what actions are scientificallyappropriate in studying and detecting near-Earth objects.[/size][/font]
