神舟7号
2008-10-12 14:54:38
China on Thursday successfully launched a three-man crew into space where one of them will make the country's first spacewalk, the country's most challenging space mission since first launching a person into space in 2003.
中国在周四成功的将三人小组送入太空,其中一人将进行该国首次太空行走,这是自2003年首次将一人送入太空后中国最具挑战的太空任务。
The Shenzhou 7 spacecraft, China's third manned mission, blasted off atop a Long March 2F rocket shortly after 9:00 p.m. (1300 GMT) under clear night skies in northwestern China. The spacewalk by one of the astronauts is expected to take place either on Friday or Saturday.
晚上九点后(格林威治时间13:00),在中国西北方晴朗的夜空下,神舟七号飞船,这个中国第三个载人项目,由长征2F号火箭发射升空。
The mission, expected to last three to four days, is devoted almost entirely to the execution of the spacewalk, known formally as an extra-vehicular activity, or EVA, is expected to help China master the technology for docking two orbiters to create China's first orbiting space station in the next few years.
这次任务预计持续三到四天,主要用于执行太空行走任务,太空行走正式的名称是“出舱活动(EVA)”,它将有助于中国掌握两颗卫星的对接技术,在未来几年建立中国的第一个空间站。
The two astronauts who don spacesuits for the Shengzhou 7 spacewalk will be supported by Russian experts throughout the mission. Only one will actually leave the orbiter module to retrieve scientific experiments placed outside. One of the astronauts will wear China's homemade Feitian suit, while the other will wear a Russian-made suit.
两名身穿神舟七号太空行走航天服的宇航员将由俄罗斯专家提供全程技术支持。只有一个人将实实在在的离开卫星舱在太空中进行实验。其中一名宇航员穿的是中国自制的“飞天”航天服,另一名穿的是俄罗斯制造的。
Fighter pilot Zhai Zhigang, an unsuccessful candidate for the previous two manned missions, has been touted by the official Xinhua News Agency as the leading astronaut to carry out the spacewalk, expected to last about 40 minutes.
航天员翟志刚曾落选前两次的载人任务,据新华社消息称他极有可能执行这次预计持续40分钟左右的太空行走任务。
"The Shenzhou 7 mission marks a historic breakthrough in China's manned space program," Zhai said. "It is a great honor for all three of us to fly the mission, and we are fully prepared for the challenge."
翟志刚说:“神舟七号是我国载人航天事业的历史性突破,我们三人能出征太空是我们的最高荣耀,我们已经做好了充分的准备来迎接挑战。”
China will launch its third manned spacecraft Shenzhou-7 from Jiuquan Satellite Launch Center in northwest China on Thursday, a spokesperson with China's manned space program said on Wednesday.
The first Chinese astronaut is likely to walk in space around 4:30 pm on Friday, a day after spacecraft Shenzhou VII lifts off, the commander-in-chief of the mission's ground operation has said.
The historic moment will be broadcast live across the world, xinhua.net quoted Cui Jijun as having said yesterday, and the space environment is expected to be fine for the mission.
The Shenzhou-7, carrying three taikonauts, will be launched on a Long-March II-F carrier rocket and then moved into orbit at an altitude of 343 kilometers.
有用的句子:
Zhai Zhigang, a reserve for the Shenzhou V and VI missions, is poised to become China's first spacewalker, reports have said.
有消息说,最有可能进行中国航天首次太空漫步的是曾经2次入选神舟计划的航天员翟志刚。
The most likely takeoff time for Shenzhou VII is 9:10 pm on Sept 25, the website said.
据了解,神舟七号会在本月25号晚上8点到9点钟升空。
Zhai is expected to conduct a 40-minute spacewalk
这一太空漫步将大约进行40分钟。
Two astronauts who are scheduled to perform the extravehicular activities (EVA)will each wear the Orlan and the Fetian suit, and Russian experts will provide technical support for the process。
两名航天员分别穿国产和俄罗斯舱外航天服进入轨道舱。俄罗斯专家将提供技术支持。
All six members of the Shenzhou VII mission belong to China's first generation of 14 astronaut candidates, selected in 1998.
神舟七号所有六名成员都是来自从1998年挑选出来的14名第一代航天员。China on Thursday successfully launched a three-man crew into space where one of them will make the country's first spacewalk, the country's most challenging space mission since first launching a person into space in 2003.

神舟7号
2008-10-12 14:50:56
2008年9月25日21时10分,长征二号F运载火箭载着神舟七号载人飞船,载着中华民族冲击太空新高度的梦想,飞上太空。
这是神舟飞船第七次飞入太空,也是中国人第三次登上太空。
继杨利伟实现中华民族飞天梦想,费俊龙和聂海胜进入轨道舱开展空间科学实验之后,今天,翟志刚、刘伯明、景海鹏三位中国航天员的金秋之行,肩负着全新的历史性使命——按照计划,他们将在此次太空飞行中,实现出舱行走。
中国人,将首次在太空中留下自己的足迹——这一看不见的足迹,必将作为最难忘的前进步伐,永载中华民族的记忆之中。
梦想有多远,前行的步伐就能迈多远。从1992年启动载人航天工程到1999年神舟一号试验飞船起飞,从神舟五号一人一天飞行到神舟六号两人多天飞行,在实现了一系列从梦想到现实的突破之后——中国载人航天,又一次迈到了一个重大的跨越关口。
实现太空行走,对于世界上任何一个航天大国,都是历史性的一步。正是航天员出舱维修,使科学家们至今仍能享受1990年4月发射的哈勃太空望远镜提供的宝贵资源,而设计寿命5年的“和平号空间站”超期服役10年,开展科学试验16500余项的奇迹,更是与航天员不断的出舱维修密不可分……实现太空行走,在任何国家的载人航天历程中都是具有里程碑式的突破:它意味着航天员可以自主出舱来维修价值高昂的航天器,建设和组装空间站。
现在正在建设的国际空间站,就需要航天员在太空的参与。而人类“重返月球”和更远的深空探测中,航天员空间行走更是必不可少。
航天员出舱活动,技术难度高、风险性大,无论技术攻关、产品研制、航天员训练,还是任务组织指挥,都面临前所未有的挑战。也正因如此,自1965年3月18日苏联航天员列昂诺夫首次踏足太空,43度春秋过去,世界上依然只有美、俄两国拥有完整的出舱行走技术和经验。
然而,正如中国载人航天工程总设计师周建平所说的一样,在实现千年飞天梦想之路上大步前进的中华民族,有勇气来迎接这样的挑战。
如果此次航天员出舱行走顺利,下一步的神舟飞行就将进行航天器交会对接试验,然后,就是开展具有一定应用规模的短期有人照料、长期在轨自主飞行的空间实验室的研制,再往后,就是长期有人值守的空间站……。
现实的辉煌,从来始于伟大的梦想。从渔船、出租车上的GPS全球定位导航仪到几乎家家都有的卫星广播电视,从气象预报、信息网络到餐桌上的“太空稻米”、“太空蔬菜”……今天,我们已经生活在一个广泛应用“太空文明”所带来成果的时代
太空,不仅为我们提供了高度资源、微重力资源、超高真空资源、无限的能源和物质资源,而且为我们提供了广袤无垠的空间资源,甚至能够为我们开拓出无穷的生存空间,为我们创造出全新的生活方式……
但是,人类对太空的探索和开发才刚刚起步。即使我们顺利实现了出舱行走的历史性突破,无垠的宇宙依然有无数的奥秘等待着我们破译。
光荣与梦想始终紧紧相连。作为最早产生飞天梦想的民族,还在饿着肚子的时候,就曾把“两弹一星”的梦想变成了辉煌的现实。我们有理由相信,在新一轮空间探索热潮已然兴起的今天,中华民族用自己的飞天智慧造福人类的时代已经到来。
神舟七号,预祝你圆梦而归。

英语教学中教会学生质疑
2008-10-01 22:06:56
英语教学中教会学生质疑[ 作者:佚名 | 转贴自:中国教育报 | 点击数:1515 | 更新时间:2005-8-26 ] 众所周知,学生的思维过程往往从问题开始,在英语阅读教学中,教师要有意识地诱导学生质疑问难。那么,怎样培养学生的质疑能力呢?笔者认为应该从以下几个方面去把握。
营造良好课堂气氛
高中学生的问题意识还不够强,在学生的质疑过程中,难免会提出一些“幼稚”的问题,在这种情境中,教师可以通过下列方式创造学生喜爱的环境:通过多种形式肯定学生的提问,比如,面部表情、手势动作以及充满赞赏的话语;尊重学生的不同见解;赏识学生的独创。只要学生有一点新思想、新发现,就应该表扬和鼓励他们,让他们看到自己的价值。
把握三个阶段
第一阶段教师要根据“初读感知——细读理解——精读品味”的阅读顺序和学生由浅入深的认知规律,指导学生掌握略读或粗读的方法。比如,首先让学生快速地阅读全篇,掌握所读材料的主旨和大意,设计一些浅层性的问题。对于篇幅较长或信息较多的文章可以用图示法列出重要信息项目,再设计问题。对于文章中尚未弄懂的知识,比如生词、短语、句子、语境等,要指导学生根据上下文,并利用所掌握的句法、构词法和词汇,设计一些猜测性的问题。这一阶段的问题属于初级阶段,答案可以直接在文章中找到。
第二阶段是学生细读以后可以设计两类问题,一类是找出文章中的重要事实或细节设计理解性问题,另一类是辨认哪些细节在文章中没有被提及等问题。教师要鼓励学生放开手脚、广开思路,鼓励他们用自己的语言把想法和认识通过问题形式表达出来。教师还要根据学生的个体差异以及在阅读中所产生的好奇、好问、困惑、矛盾等心理特点,采用小组讨论争辩的方式来解决问题。在学生的质疑过程中,教师要有目的、有意识地让学生对所学知识的内涵和外延进行探讨和争辩,鼓励学生提出相互矛盾或两难判断的问题,然后通过师生间的相互启发,达到异中求同,最后,形成一个紧扣教学目标,有目的性、全面性的问题链,最后教师统筹解决,达到培养学生分析问题和创造性解决问题的能力。
第三阶段可以要求学生研读文章,对文章作进一步探究。当学生细读文章时,要指导学生围绕其结构特点及中心思想去提问,比如,如何认识作者的写作目的,发现作者的失误和偏漏,对作者的观点提出异议,品味文章的写作特色,如何进行推理判断等,这类问题需要跳出“因循守旧”的框架,所以要求学生树立“标新立异”的观念,从不同角度、不同地方进行思考和分析,用自己独特的思路设计真实反映自己的所想所感的问题。
教师在每一阶段都要抽出足够的时间让学生在组内进行相互合作交流,提出个人的疑难问题,简单的当场解决,较重要的和较难的问题经过认真筛选后在全班交流。筛选问题不仅是选择的过程,而且还是完善、合并、修正说法的过程。在组内交流时要求学生把在思考问题时的思维过程描述出来,这对其他学生有一定的启发和帮助。
