“记忆术”很多，比如《二十四节气歌》：春雨惊春清谷天，夏满芒夏暑相连，秋处露秋寒霜降

田世国是山东枣庄市薛城区人，他不仅是一名好父亲，更是一名好儿子。为了不让母亲为他担心，38岁的他毅然瞒着母亲，为身患尿毒症晚期的母亲捐肾，延续母亲的生命，演绎了一段当代孝子的佳话。因此田世国入选2004年感动中国十大杰出人物。授予他的颁奖词是这样的：“谁言寸草心，报得三春晖？”这是一个被追问了千年的问题。一个儿子在用身体做出了自己的回答，他把自己生命的一部分回馈给病危的母亲。在温暖的谎话里，母亲的生命也许依然脆弱，但孝子的真诚已经坚如磐石。田世国，让天下所有的母亲收获慰藉。

In the past year, a lot has changed in the field of human spaceflight. (46)In January, President George Bush brushed aside the fact that America’s entire space-shuttle fleet was grounded when he announced grandiose plans to put people back on the moon, and then to launch a manned mission to Mars. (47) In June, Burt Rutan, an American aeronautical engineer, showed that human spaceflight was no longer the preserve of governments by sending a man to the edge of space in Space Ship One, a privately financed vehicle that cost about the same to build as a luxury yacht. That was followed in September by Sir Richard Branson, the British entrepreneur behind the Virgin brand, announcing that he had signed a deal with Mr. Rutan to work on plans for a fleet of five suborbital vehicles developed from Space Ship One.

(48) Now, in the dying days of the year, America’s Congress has passed a bill that unravels a tangle about who would be responsible for regulating the fledgling industry, and under what terms. (49) The bill also allows passengers to fly, on the understanding that this new generation of vehicles may not be as safe as taking a commercial flight between, say, New York and London.

The official line from Virgin Galactica, as Sir Richard’s latest venture is modestly named, is that this coming change in the law makes no practical difference to the firm’s plans, since they do not intend to fly unless they can make their spacecraft as safe as a private jet. But it must surely come as some sort of relief. In any case, Will Whitehorn, director of corporate affairs at Virgin’s headquarters in London, and soon to become the president of Virgin Galactica, says that work is under way on a mock-up of the interior of a new spacecraft that will hold five passengers. (50) Virgin has already committed $20m towards licensing the SpaceShipOne technology from Mr. Rutan and his financial backer Paul Allen, a software billionaire.
