我们工作的原因英文作文【一】
近视，是眼睛看不清远物、却看清近物的症状。在屈光静止的前提下，远处的物体不能在视网膜汇聚，而在视网膜之前形成焦点,因而造成视觉变形,导致远方的物体模糊不清。近视分屈光和轴性两类。其中屈光近视最为严重。屈光近视可达到600度以上，即高度近视。
疾病：相当数量的患者曾患过麻疹、百日咳等传染病，这些患者大多出现眼球膨大，而眼球处于膨大状态时，眼球的屈光度下降，视力减弱。
噪音：有关专家的研究表明，当音响强度在90分贝以上时，眼底视网膜中视杆细胞区别光亮度的敏感性开始下降，识别弱光反应的时间延长，超过45分贝时，40%的人瞳孔散大，达到115分贝时，眼睛对光亮度的适应性下降20%，同时伴有色觉能力削弱。
矿物元素不足：医学研究表明，钙、铬等矿物元素是保证青少年视力正常的一个重要条件，钙元素在维持眼晶体正常压力，铬元素在保持眼睛屈光度等方面都有不可替代的作用。特别要提醒注意的是，加工过细的米、面，会丧失80%的铬元素，故意吃一些粗粮有益于视力健康。
吃甜食太多：甜食为酸性食物，一方面大量消耗体内的钙元素，另一方面升高糖，改变晶体渗透压，是导致近视眼形成的又一祸根，监督孩子少吃为妙。
5被动吸烟：德国专家发现，烟草中含有一种毒性较强的氰化物，它在人体内积存到一定程度，可造成中毒性弱视。而青少年的眼球正处于发育期，对烟草中的有害物更为敏感。
6睡眠不足：10—13岁是近视眼形成的高峰期。此年龄段的孩子若睡眠不足，交感与副交感神经功能失去平衡，造成眼睫状肌的调节功能紊乱，故保证每晚睡足9—11小时，有保护视力的作用。

dear sir or madam:
i am xxx, general manager of xxx. learning that an excellent staff member of ours, mr. xxx is intent on further studying abroad, i am much pleased and gratified. in my opinion, such a promising youth striving for progress should receive better education so as to create a brighter future. therefore, it gives me a high honor to strongly recommend this outstanding young man to your world-renowned university.

by now, as a business elite of ours, mr. xxx works even seriously, responsibly and diligently, setting a good example to other staff members. every drop of sweat will be repaid. mr. xxx has been appraised as excellent employee of ours and awarded considerable bonus.

respectfully yours,

我们工作的原因英文作文【三】
她是一个尖子生，深受兰老师的宠爱，做什么都认真，从不半途而废，尤其是体育活动。
就拿踢毽来说说吧，他每天早晨7:20准时去，下午4;00也要去练习，不管天晴落雨，不管严寒酷暑。特别是在炎夏火红的太阳象在和大地过不去一样，把大地烤得直冒烟，人站在阳光下，脸上也是火辣辣的疼，头发也能当个烤火炉，而她却从未放弃或抱怨过，只是在炎炎烈日下辛苦的练着，汗水常常把额前的刘海打湿成一根一根的，背后的衣服水淋淋的，满脸通红，汗水在他的脸上流淌着，大颗大颗的汗珠滴在地上，发出啪的一声，这样子，活像刚洗完澡从浴室了出来似的，水也没擦。同时，她还有长绳一项，是他原本不多的时间更加的紧凑了，连玩的时间也寥寥无几，而她却不在乎，还是默默的.练着。
除了她在体育项目上忙外，她在班上忙的也是不亦乐乎，上气不接下气，为什么？因为她是中队长呗，还是兰老师的乖乖女，一有什么事，兰老师就叫她出马，每次回来都累得气喘吁吁。她在课堂上也是不会闲着的，一但有什么较难的课堂难题，她都要帮我们解围，回答的头头是道，我从心眼里佩服她，喜欢她。她也喜欢现在的生活，因为她活得充实，“累”得快乐。
兰老师之所以喜欢她，不仅仅因为他成绩好，还因为她做任何事很有积极性，有责任感，学习有上进心。在我的印象中，班上的一切活动，差不多都有她的参与，而且办得既快又漂亮又简洁，十分满意，他从来不打打闹闹，说说脏话，是班上名副其实的三好学生，她也很活泼，对人有善，同学们都爱和她玩，说心里话，很愿意对她分享自己的小秘密，她也时不时说说自己的秘密。我们一直都是形影不离，无话不说的好朋友，同舟共济，相互关心，亲密无间。
这就是我们班的“工作狂”，你觉得咋样？一定吃惊坏了吧，万万没想到世界上还有这类型的稀有“品种”。今天，你们大饱眼福了吧！
