Beloved father:
It’s a long time no contacting with you since last e-mail. And I miss you so much. Recently I luckily turn to the third officer working on board MV Blue Whale,which is a container ship. I intend to introduce you what Ido on this big vessel in this letter.
I am the third officer working in the deck department. As you know, the third officer is responsible to the master for the proper performance of his assigned bridge watchstanding and navigational duties.
On board, my first daily work is wathckeeping from 8 to 12 and from 20 to 24. my second daily work is in charge of the maintance of the fire-fighting equipment and life-saving equipment. The third , I am also responsible for fire and boat drills, I have to design a muster list and make crew to know the best escape route clearly. Additionally, there are also some simple things I have to do in daily work. For example, I have to assist the Chief Officer in supervising cargo handling operation 、to measure the draft at the discretion of the Chief Officer or the Master、to assist the Master on the bridge with anchoring and mooring and unmooring operation is underway and so on.
In the end, I strongly believed that you must be very familiar with my special work through what I said. And I hope you can stand my back and make me stronger. We will have a reunion soon.
Your ,ZJH
双燕今朝至,何时发海滨?
窥人向檐语,如道故乡春。
——徐璧《春燕》
燕子的种类很多,有家燕、金腰燕、石燕、砂燕等,最常见的是家燕。家燕是一种候鸟,不但秋去春来,历年不炎,而且又多能返归故居,重入旧巢。据近代的研究,成鸟翌年返归旧巢率为47,1%,雏鸟翌年返归旧巢率为16%,有的竟能连续四年返回旧巢,正如《汉乐一府》中所说“翩翩堂前燕,冬藏夏来见”。所以每当燕子飞回来时,人们见到它们都有一种“似曾相识”的亲切感。
燕子(主要指家燕春来何处?秋去何方?据研究,燕子分布很广,在越冬时期,它们不仅遍及东南亚,并且远达澳洲北部,春来渐次北返,二月初达广东,三月初至福建,中旬达长江下游,四月初达黄河流域,再北就更迟。秋去一般始于八月终于十月。燕子飞行的速度很快(每秒98米,每次迁捉,体脂增多,体力健壮,常常数万成群,每日可行140公里(直线行进220公里:虽然如此,但仍旧是一种艰苦的行程,所以燕子在海上飞行时,多取岛屿连绵的路线,以便途中休息,在陆上飞行时,也多是在白天,飞行一程休息一阵:如飞渡浩渺的南太平洋海面,更加艰险,常常要忍饥受饿,甚至数日不得饮食,勉力渡过。而当年雏鸟由于体力不胜,80%在途中掉了。
燕子是亲近人们的鸟类,人们也很喜爱它,清脆的燕语,不停地在叫“吉骨,吉骨,住!吉骨,吉骨,住!……”仿佛在说:“不借你们的盐,不借你们的醋,只借你们的屋,给我们来住住。”我国民间还普遍存在着这样的思想,认为“燕子来巢,吉祥之兆”。当然燕子并不会预兆什么,但它确是捕捉害虫的健将,因此可以给人带来很大的好处。燕子一般每年育雏两次,育雏期间,亲鸟辛劳,终日不息,雏燕贪食,整天张口。真是“须臾十来往,扰恐巢中饥;辛勤三十日,母瘦雏渐肥。”(白居易诗。据观察,亲燕喂雏每小时达9到15次,每天约180次;平均每天捉虫约450只,加上亲燕自己捕食,总共不下五六百只,不难看出一对亲燕和它的两窝雏燕从四月到九月吃虫数字的惊人了。即以一只家燕而言,一个夏天就能吃掉50万到100万只昆虫——都是些蝇、蚊等害虫和牛蛇、蛇春象、楼姑等农业害虫。
我们必须大力保护燕子,不使其遭受伤害,不捣燕窝,不取燕卵,随时注意防止家猫等动物破坏燕巢捕食雏鸟。在燕子南迁以后,尤要尽力保护旧巢,以备缩短其来年修造窝巢的时间,这不仅直接有利于燕子两次繁殖育雏,更可间接促进农业的丰收。
燕子喜欢停在电线上,一双肉色的小爪子紧紧地抓住电线。它全身的羽毛乌黑光亮,光彩照人。头上的羽毛像一顶黑帽子。如果说背上的羽毛像穿了一件黑色西服的话,那腹部的羽毛就像给小燕子穿了一件雪白的衬衫。整个看上去,就像一位绅士。燕子活泼机灵,小小的脑袋上嵌着宝石般的眼睛,剪刀似的尾巴保持着身体的平衡。
燕子呢喃细语,喜欢在水面上舞蹈,一眨眼,又轻轻地停到电线上了。它一动不动地注视着天空,等待飞到它身边的小飞虫。
调皮的小飞虫悄悄地向田里飞去,尽管它这样机灵,还是难以逃脱小燕子锐利的眼睛。燕子蹬开电线,用它那尖尖的嘴巴一下子叼起了小飞虫,往远处飞走了。只有电线还在摇晃,微风还在吹动。
我喜欢燕子。因为它不仅是春天的使者,还是人类的好朋友。它从南方飞回来,向人们宣告春天的到来;它帮助人们为庄稼捉害虫,确保秋天的丰收。我们要赶紧行动起来保护燕子,共同创造一个美好的大家园。
