    沛公旦日从百余骑来见项王，至鸿门，谢曰：“臣与将军戮力而攻秦，将军战河北，臣战河南，然不自意能先入关破秦，得复见将军于此。今者有小人之言，令将军与臣有郤……”项王曰：“此沛公左司马曹无伤言之。不然，籍何以至此？”项王即日因留沛公与饮。项王、项伯东向坐；亚父南向坐——亚父者，范增也；沛公北向坐；张良西向侍。范增数目项王，举所佩玉玦以示之者三，项王默然不应。范增起，出召项庄，谓曰：“君王为人不忍。若入前为寿，寿毕，请以剑舞，因击沛公于坐，杀之。不者，若属皆且为所虏！”庄则入为寿。寿毕，曰：“君王与沛公饮，军中无以为乐，请以剑舞。”项王曰：“诺。”项庄拔剑起舞。项伯亦拔剑起舞，常以身翼蔽沛公，庄不得击。

    于是张良至军门见樊哙。樊哙曰：“今日之事何如？”良曰：“甚急！今者项庄拔剑舞，其意常在沛公也。”哙曰：“此迫矣！臣请入，与之同命。”哙即带剑拥盾入军门。交戟之卫士欲止不内。樊哙侧其盾以撞，卫士仆地，哙遂入，披帷西向立，瞋目视项王，头发上指，目眦尽裂。项王按剑而跽曰：“客何为者？”张良曰：“沛公之参乘樊哙者也。”项王曰：“壮士！——赐之卮酒。”则与斗卮酒。哙拜谢，起，立而饮之。项王曰：“赐之彘肩。”则与一生彘肩。樊哙覆其盾于地，加彘肩上，拔剑切而啖之。项王曰：“壮士！能复饮乎？”樊哙曰：“臣死且不避，卮酒安足辞！夫秦王有虎狼之心，杀人如不能举，刑人如恐不胜，天下皆叛之。怀王与诸将约曰：‘先破秦入咸阳者王之。’今沛公先破秦入咸阳，毫毛不敢有所近，封闭宫室，还军霸上，以待大王来，故遣将守关者，备他盗出入与非常也。劳苦而功高如此，未有封侯之赏，而听细说，欲诛有功之人，此亡秦之续耳。窃为大王不取也！”项王未有以应，曰：“坐。”樊哙从良坐。坐须臾，沛公起如厕，因招樊哙出。

项羽说：“此沛公左司马曹无伤言之。”从中可以看出项羽什么样的性格特征。

    The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

    As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

    Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii.

    The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

    To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos（胚胎）. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

    Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that can be cheaply extracted, especially in countries that can't afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

    The rabbits are expected to have the same life span as their non-glowing counterparts（副本）, but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

    "To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

    Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.
