Towards evening the mate and boat-swain begged the master of our ship to let them cut away the foremast, which he was very unwilling to: But the boat-swain protesting to him, that if he did not, the ship would founder, he consented; and when they had cut away the foremast, the main-mast stood so loose, and shook the ship so much, they were obliged to cut her away also, and make a clear deck.

临近傍晚，大副和水手长请求我们的船长让他们砍掉船头第一根桅杆；船长当然是很不愿意干的。但水手长坚持说，如果船长不这样做，船就会被风浪击沉；船长同意了。当他们把这根桅杆砍掉，主桅杆就站立不稳，船也随着剧烈摇晃，他们又只得把主桅杆也砍掉。这样就只剩下一个空荡荡的甲板了。

And yet, in Raissa, at every moment there is a child in a window who laughs seeing a dog that has jumped on a shed to bite into a piece of polenta dropped by a stonemason who has shouted from the top of the scaffolding,"Darling, let me dip into it," to a young serving maid who holds up a dish of ragout under the pergola, happy to serve it to the umbrella-maker who is celebrating a successful transaction, a white lace parasol bought to display at the races by a great lady in love with an officer who has smiled at her taking the last jump, happy man, and still happier his horse, flying over the obstacles, seeing a francolin flying in the sky, happy bird freed from its cage by a painter happy at having painted it feather by feather, speckled with red and yellow in the illumination of that page in the volume where the philosopher says:"Also in Raissa, city of sadness, there runs an invisible thread that binds one living being to another for a moment, then unravels, then is stretched again between moving points as it draws new and rapid patterns so that at every second the unhappy city contains a happy city unaware of its own existence."

可是，在莱莎的每一刻钟都听得到窗旁的小孩的笑声，因为他看见一头狗扑上小屋抢吃一块烧饼；烧饼是棚架上的石匠掉下的；他当时正在向一个年轻的女侍应员高声喊叫："好人，让我尝一尝"；那年轻女子正捧着肉汤满心高兴地送给一个庆祝交易成功的制伞工人；爱上青年军官的一位贵妇人在赛马场炫耀她的镶花边的白阳伞；马背上的军官最后一次跳跃时向她笑了一笑；他是个快乐的人，不过他的马比他更快乐，它跳栏的时候看见鹧鸪在天上飞；快乐的鸟儿刚被一位画家放出囚笼；快乐的画家完成了鸟的插图，描出它每一根红黄斑点的羽毛；插图的书页上有哲学家的话："忧愁的城市莱莎也有一根无形的线，在某个顷间把一个生物连系上另一个生物，然后松开，又在两个移动的点之间伸展，快速画出新的图形，因此，不快乐的城市在每一秒钟都包藏着一个快乐的城市，只是它自己并不知道罢了。"

Result It was found in the results that the better pretreatment time for onion root-tip was 3.0 h and its better dyeing solution was basic fuchsin dyeing solution. On this basis, it was found that the chromosome number of tested onion was 2n=2x=16 through chromosome karyotype analysis on the root-tip cells of onion.

结果］结果发现，洋葱根尖的较好的预处理时间为3.0 h，较好的染液为碱性品红染液；在此基础上，通过洋葱根尖细胞染色体核型分析，发现试验所用洋葱的染色体数为2n=2x=16。

MATERIALS AND METHODS: The root tips of Vicia faba were treated with different concentrations of sodium sulfite and sodium nitrite (in the concentrations of 25;50;100;200;400 mg/L) with distilled water as control for four hours.The root tips of Vicia faba were stained with carbol fuchsin and examined. The micronucleus rate and the rate of chromosome aberration were determined within root tip cells of Vicia faba.
