饮食,我认为主要是一日三餐。人在生活中每天身体内需要的营养就来源于三餐之中,为学习工作提供能量。所以,人们常说:“早餐要吃好,午餐要吃饱,晚餐要吃少”这一养生经验是有道理的。
早餐不但要注意数量,而且要讲究质量。主食一般吃含有淀粉的食物。如:牛奶、豆浆、鸡蛋等,能使体内的血糖迅速升高到正常或超过正常标准,从而使人精神振奋,精力充沛的.工作或学习。对经常不吃早餐的人来说,不但工作或学习达不到精力充沛的最佳状况,还容易发生胆结石。
午餐应适当多吃些,而且质量要高。主食一般是米饭、馒头、面条等,副食品增加些富含蛋白质和脂肪的食物,如:鱼类、肉类、蛋类和豆制品等,以及新鲜蔬菜。使体内血糖继续保持在高水平,以保证下午的工作或学习。否则,如果因工作或学习紧张,会把脑中供应的这些神经传递消耗殆尽,供不应求,就会影响工作或学习。
晚餐要吃得少,应以清淡,容易消化为原则,至少要在睡觉前两小时进餐。如果晚餐吃得过多,并且吃进大量含蛋白质和脂肪的食物,不容易消化,也会影响睡眠。
另外,无论工作或学习再忙再紧张,吃饭一定要做到定时定量,不要暴饮暴食。这样会有利于肠胃有规律并正常工作,否则,容易造成消化不良,对身体更为不利。
总之,一日三餐要巧安排,养成良好的饮食习惯,从食物中摄取营养物质,以保证身体的健康。
Imagination is the ability to form a mental image of something that is not perceived through the senses. As to the attitude towards imagination, it varies from person to person. Some people think that imagination is good for many things. First, imagination makes it possible to experience a whole world inside the mind. Secondly, imagination has a great role and value in each one’s life.
However, some people hold a negative view on it. They think it does not matter whether you have imagination or not. First, imagination is not practical, which makes people daydreamers. Second, people sometimes do not have to be imaginative in life or work. If they follow the step-by-step schedule, they also would succeed. In their eyes, imagination is a creative power but it is not necessary to achieve success in any field.
As I am concerned, I think we should recognize the importance of the power of the imagination, maintain, and develop our imagination as time steps. Understanding how to use your imagination correctly will put you on the golden path to success, satisfaction, and happiness.
