Recently I have been thinking of my life, ‘who will I be, I like who I will be, my family likes who will be, and How about my friends thinking about me?’ I do know I just wanna lead a simple life, however, in a real society, it seems to become a word that is easy to say but difficult to take an action. Some time I thought the life I want possibly was unreal. All as below are about my life: 1. Listening to your heart in a quiet circumstance. 2. If you’re looking for a helping hand, please look at the end of your arms. 3. Do what you must do firstly, and then do what you possibly need to do , finally do what you like to do. 4. Treat others sincerely and honestly, especially your friends and your family. 5. Never stop self-learning and making the improvement for myself. 6. Build up your interests in my life and look for ...

电脑主机、显示器、鼠标、键盘及周围的相关设备都会产生辐射，眼睛看不见，手摸不到。据科学研究表明：电脑产生的低频电磁辐射对人体造成的伤害是隐性的、积累的，人们经常（长期）在超强度的电脑低频电磁辐射环境中使用电脑，导致头晕、头痛、脑涨、耳鸣、失眠、眼睛干涩、视力下降、食欲不振、疲倦无力、记忆力减退、部分人脱发、白细胞减少、免疫力底下、白内障、白血病、脑癌、乳癌、血管扩张、血压异常、胸闷、心动过缓、心搏血量减少、窦性心率不齐、男性精子质量降低、部分女性经期紊乱、孕妇流产、死胎、胎儿畸形、生殖病变、遗传病变、癌症等可怕疾病。人在操作电脑后，脸上会吸附许多电磁辐射颗粒，经常遭辐射会出现脸部斑疹。一个人连续操作电脑工作五小时，电脑产生的低频辐射对人体的伤害，相当于一天的生命损失。 房间里电脑数量越多，摆放越密集，空气中的低频电磁辐射量越大，对人体的伤害越大。电脑显示器（屏）的北部辐射强度大大超过显示器（屏）正面的辐射强度。有些企事业单位使用电脑的工作岗位，学校电脑教室和一些网吧前后、左右近距离横排摆放电脑，前排 人员背对着后排电脑显示器的背部，前后、左右近邻电脑，受到的伤害更大。即使在显示器上挂一个一般的"辐射防护网（板）"也只能阻挡来自显示器正面的一少部分辐射。不能解决根本问题。不少人误认为，只要用"液晶显示器"更换掉电脑上的"普通"（玻璃）显示器，就可以完全消除电脑主机、显示器、鼠标、键盘及周围相关设备上的所有辐射。其实根本不可能消除电脑整机中各部分的所有辐射，而仅仅是以高额投资减少了"显示器"上的局部辐射，但仍无法消除电脑主、鼠标、键盘及周围相关设备上的电脑辐射照样伤人的难题。 夸张了些，不过提醒大家平时工作提高效率，不然生命白白地流逝了。：） 电脑的终端是监视器，它的原理和电视机一样，当阴极射线管发射出的电子流撞击在荧光屏上时，即可转变成可见光，在这个过程中会产生对人体有害的X射线。而且在VDT周围还会产生低频电磁场，长期受电磁波辐射污染，容易导致青光眼、失明症、白血病、乳腺癌等病症。据不完全统计，常用电脑的人中感到眼睛疲劳的占83％，肩酸腰痛的占63．9％，头痛和食欲不振的则占56．1％和54．4％，其他还出现自律神经失调、抑郁症、动脉硬化性精神病等等。 ...

今晚偶将乘坐列车回家，不过列车不是2046。 何时喜欢上坐火车的感觉，自己也记不大清楚了。每次坐在列车上，随着火车咔嚓咔嚓的声音，自己的记忆会一点点被唤醒，或许是自己有点恋旧情节，或许现实生活中总有些不如意，以致我喜欢那种感觉，坐在窗边看着外面的风景，思绪随着速度，随着风景而去...... 收拾房间啦，准备出发！~

To continue on the discussion of VAT 2010 changes we want to provide more insight into the scope of these changes. Starting on January 1, 2010, all businesses in the European Union need to be in compliance with the fundamental changes to the VAT system agreed on by the ECOFIN in December 2007 and adopted in February 2008. Any size company in any industry has the potential to be impacted. Businesses with complex supply chain operations and complex selling models will be impacted the most. And while these changes – dealing primarily with place of supply of services and the recovery of VAT of purchases made in other EU countries – will modernize and simplify current rules, they will also be highly disruptive. In order to comply, businesses will need to determine exactly how they will be individually effected by the changes. They will have to retool their financial systems. And they will have to redefine business processes and retrain employees. Yet sometimes disruption can be a ...
