阅读下面科普短文(本文由网络文章改写)。
松花蛋又称皮蛋、变蛋、灰包蛋等,因剥开蛋壳后胶冻状的蛋清中常有松针状的结晶或花纹而得名,是一种我国传统风味食品,口感鲜滑爽口,色香味均有独到之处。中医认为,松花蛋性凉,对牙痛、眼痛等疾病有一定疗效。由于松花蛋会有一股碱涩味,在吃松花蛋的时候可以加入少量的姜醋汁。
松花蛋是用料泥包裹鸭蛋、鸡蛋等加工而成。料泥是由生石灰、纯碱、食盐、红茶、草木灰(主要成分K2CO3)等原料与水按比例混合均匀制得。料泥制作过程中,通过一系列反应,产生的强碱(NaOH、KOH)经蛋壳渗入到蛋清和蛋黄中,与其中的蛋白质作用,致使蛋白质分解、凝固并放出少量硫化氢气体和氨气。同时渗入的碱还会与蛋白质分解出的氨基酸进一步发生中和反应,生成的盐的晶体沉积在凝胶态的蛋清中,便出现了朵朵“松花”。而硫化氢气体则与蛋清和蛋黄中的矿物质作用生成各种硫化物,使蛋清和蛋黄的颜色发生改变,蛋清呈特殊的茶褐色、蛋黄则呈墨绿色。下图表示松花蛋腌制时间与其中蛋清和蛋黄的pH的变化关系。

很多人在平时生活中都非常喜欢吃皮蛋瘦肉粥、凉拌松花蛋,专家提醒这种食物少吃无妨,却不能过多食用。其一,松花蛋腌制过程中蛋白质分解、变质,导致营养价值遭到了一定的破坏。其二,市售松花蛋还可能含铅(国家规定松花蛋中铅含量需小于0.5 mg/kg)。微量铅很容易被儿童吸收,导致铅中毒。其三,剥开皮的松花蛋1至2小时内一定要吃完,若长时间暴露在空气中,非常容易感染沙门氏杆菌,沙门氏杆菌会快速繁殖,此时食用松花蛋很容易引起中毒现象。

    You have probably been told by your high school instructor that writing is an important and practical skill. However, you may not be convinced that the ability to write will be important in your own future. If so, you will be surprised at the results of a recent survey by the National Institute of Education. More than four thousand working men and women who had graduated fifteen years earlier were asked to name the courses they would have taken in college if they had known better. The designer of the survey expected people to name courses in computer science, mathematics, or business. But the course most often mentioned was writing.

    If you already have a job, you are probably not surprised at their answers. Many jobs require the ability to write. Despite the increasing use of the telephone and the computer, much information must be communicated in writing.Some ten million people—managers, engineers, sales representatives, and many others— write regularly as part of their jobs. Summaries, reports, reports, letters and speeches are required in today's work world. The ability to write, therefore, is an important skill. The successful individual is almost always the one who can communicate successfully in writing.

    Writing communicates your thoughts and feelings to others; it also tells you something about yourself. Maybe this is what Eldridge Cleaver had in mind in his autobiography, “I started to write... to save myself...I had to seek out the truth... I had to find out who I am and what I want to be ,what type of man I should be ,and what I could do to become the best of which I was capable.”
