景海鹏现为中国人民解放军航天员大队特级航天员，少将军衔。2008年和2012年，他分别执行了神舟七号和神舟九号载人飞行任务。
6年前，阳光帅气的河南人陈冬成为中国第二批航天员中的一员。这是他的第一次太空之旅，也是我国第二批航天员中首个飞天的男航天员。“这是我第一次执行航天飞行任务，我会珍惜在太空中的每一刻。”今年38岁的陈冬说。
对于与景海鹏一起执行任务，陈冬觉得很幸运。“在工作中，是我的老师，在生活中，是我的兄长，他工作非常认真，要求非常严格，经验非常丰富。”他说，“这次能与景海鹏师兄组成飞行乘组，我心里很踏实、非常有底气。”
按照计划，中国空间站将于2020年前后建成。“中国空间站是中国人的太空家园，是每一名航天员的梦想宿营地。”景海鹏说，“我期待着为空间站建设发展多作贡献。只要祖国需要，我坚决听从召唤。”
“我和陈冬已经做好各方面准备。”景海鹏说，他和陈冬将带着家人共同的梦想去执行任务，一定用尽善尽美的表现，向祖国交出一份优异的答卷。
见面会是在酒泉卫星发射中心问天阁举行的。处于三级医学隔离状态的航天员坐在一面巨大的国旗下、隔着一道玻璃墙回答了媒体的提问。17日凌晨，航天员将从这里出发前往航天发射场，踏上执行神舟十一号载人飞行任务的征程。

今天，50岁的景海鹏第三次开始了自己的太空之旅。这一次，他将打破中国载人航天的多项纪录，成为中国飞的次数最多、时间最久、高度最高的航天员——继完美执行神舟七号、神舟九号飞行任务后，他创纪录地成为中国三度飞天的.第一人。
从首次太空的2天20小时27分钟飞行，到神舟九号的13天宇宙遨游，再到这次即将进行的33天的中长期驻留，他会把个人的太空累计飞行时间原纪录提高到超过48天。
按照计划，神舟十一号和天宫二号将在距地面393公里的轨道高度交会对接，比之前的交会对接轨道高了50公里。这也意味着，他和搭档陈冬一起，都将成为中国飞得最高的航天员。

Nowadays, advertisements can be found everywhere in big cities. They shout at us from the television screen and radio loudspeakers, wave to us from every page of the newspaper, signal to us from the roadside billboards all day and flash messages to us in colored lights all night.
Faced with a flood of advertisement, some people wonder whether it is necessary to have such huge sums spent on advertising. They often cite in illustration of it the attractive, but false and deceptive advertisements to which many consumers fall victim. Why don't we stop advertising and use the money to reduce the price of goods? It sounds like a good idea, but they fail to notice the contribution advertising makes to our society. Because the production of a better product to compete for customers' money is the goal of advertisers, customers are thus given a chance to compare their products and get the best and cheapest one. Besides, as the advertisement can provide people with a lot of immediate and detailed information as to the availability of a certain product, or a service or a job, it makes life much more convenient. And another thing we mustn't forget: the fact that we pay so little for our daily newspapers and TV programs is due entirely to the money spent by advertisers.
Advertising performs such a useful service to our society that we can't imagine what would happen if there were no advertisements. (198 words
