饮食与安全的英语四级作文【一】

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。

饮食与安全的英语四级作文【二】

笔者曾借助“营养”“维生素”“蔬菜”“荤菜”“肥胖”“挑食”“零食”“蔬菜”“水果”“饮料”“白开水”等概念,调查了300名3~6岁幼儿有关饮食营养概念的认知状况,结果发现,幼儿主要是根据事物可直接感知的外部特征来理解这些概念的。例如,对于“维生素”“蔬菜”“荤菜”“水果”“饮料”等集合概念,幼儿会以举例方式来表达自己的理解,而很少会依据集合的属性来定义这些概念。调查还发现,大、中、小班幼儿的概念定义水平存在显著的年龄差异;45%的幼儿不知道什么是“荤菜”;74%的幼儿能解释为什么不能挑食,73%的幼儿能解释为什么不能多吃零食,75.35%的幼儿能解释为什么不能多喝饮料,且这些幼儿大多是从挑食或吃零食、喝饮料的不良后果角度来解释原因的。〔3〕可见,大多数幼儿是依据具体举例、可直接感知的具体情境或外部特征来理解饮食营养概念的,而不是从概念的内在属性来认知的;大多数幼儿能认识到不良饮食行为对身体健康的害处,且大、中班幼儿对不良饮食行为后果的认识更加清晰。或许我们可以得出这样的结论:3~6岁幼儿已经初步掌握了一些饮食营养概念,已经懂得一些最基本的饮食营养知识,能够基本满足幼儿养成健康饮食习惯的认知需求。

笔者又通过对幼儿在幼儿园和在家的进餐行为的观察,发现幼儿的进餐行为具有以下特点:(1)因为缺少最基本的饮食营养概念认知,所以幼儿的健康饮食习惯很难建立。例如,幼儿经常会询问:“这个能不能吃?”“这是什么?是蛇(指鳝鱼)吗?”“海虾是鱼吗?”“为什么要吃这个?”如果幼儿的求知欲得不到及时满足,或相关担忧得不到及时解决,那会直接影响幼儿的进餐兴趣和进餐速度等。(2)在具有大致相同的饮食营养概念认知的前提下,幼儿的进餐表现仍存在较大差异。例如,虽然大多数幼儿都知道挑食对健康有不良影响,但是有的幼儿几乎不挑食,有的幼儿有时候挑食,有的幼儿却很挑食。(3)幼儿的进餐行为与其他生活行为的倾向趋向一致,已有的饮食营养概念认知不起决定作用。例如,平时做事磨蹭、注意力不够集中的幼儿进餐时也容易出现发呆或边进食边说笑等情况,进而影响了进餐速度。(4)幼儿喜欢吃的往往是诸如鸡腿、鸡翅、盐水鸭、大虾、红烧带鱼等口味较重的`荤菜和一些形象有趣可爱的面点。(5)幼儿不喜欢某样食物的理由多种多样。例如,幼儿不喜欢吃青菜是因为“塞牙齿”“难嚼”,不喜欢吃胡萝卜、芹菜是因为这些食物有特殊的气味,不喜欢吃苋菜是因为菜叶颜色太红,不喜欢吃螃蟹是因为害怕螃蟹张牙舞爪的形象,等等。(6)幼儿在具备一定的饮食营养概念认知却又食欲不佳的情况下,往往会以不咀嚼、不吞咽、玩弄食物、不断从锅里或大碗里盛菜到小碗里做游戏等来消极抵制进餐。笔者认为,幼儿的不良进餐习惯既受幼儿园的影响,也受家庭的影响。例如,幼儿园中、小班往往把孩子的饭菜放在一个碗里,大多数情况下都是米饭被盖在菜肴的下面,幼儿不得不先吃菜再吃饭,不能饭菜交替吃。这样的进餐习惯一旦养成,幼儿很可能在家里也是“前面吃菜,后面吃饭”,结果因为菜特别是荤菜吃得过多,主食吃不下去了。又如,许多家长尤其是祖辈家长习惯包办代替,时常主动喂孩子吃饭,结果导致孩子进餐独立性不够,在幼儿园进餐时速度很慢。有的家长为了让孩子多吃几口,时常会在孩子进餐时絮絮叨叨,想方设法甚至“不择手段”地哄孩子多吃。这时候家长向孩子灌输的营养知识往往带有误导倾向,进而容易导致孩子养成不良进餐习惯。

一日三餐究竟怎么吃?这个问题现在已经成了我们棘手的问题。为什么呢?因为我们现在的条件越来越好,但是却是越吃越不健康,然而,这种不健康的饮食习惯会把我们的身体变差,体质变弱,尤其是儿童,甚至会得一系列的疾玻到这里,我就要给大家推荐一种最为健康的饮食理念。

因为儿童活泼好动,而肝脏储备的能量有限,很容易产生饥饿感。所以儿童的一日三餐一定要吃好,才能确保儿童健康地成长。早餐要吃好,儿童必须早起,这样才能吃得下东西,吃早饭是要注意营养均衡;中午要吃饱,多吃肉、蛋、蔬菜和米饭,因为这顿中饭需要提供身体一个下午的能量;晚饭要吃少,食物要吃得清淡些,不要吃得过记饱,否则会加重胃肠负担,并影响睡眠。

你知道吗?人体到底是怎样吸收食物中的营养的吗?那么现

在,由我来告诉你们吧!

食物经过初步拒绝,通过咽喉和食道,进入胃,在胃里被进一步捣成“糊状”。口腔在细细咀嚼食物的时候,胃肠胰腺也会分泌消化液,咽下的食物团通过胃肠蠕动月消化液充分地混合。这些食物通过胃肌收缩过去进入小肠,小肠再把它们分解成可以吸收的养分。食物中的营养被小肠收服后,剩下的食物残渣就会随着小肠蠕动进入大肠,大肠进一步吸收残渣中放水份。最后,把没有用的残渣排除体外。

“人是铁,饭是钢,一顿不吃饿得慌!”这句话说得一点也没错啊!

饮食与安全的英语四级作文【六】

Sometimes I dream about life in the future. What will it be?

Perhaps some people will go to the moon for a holiday or even live on the moon,and some scientists will build cities under the sea to make people live there. We can have a medical examination or do some shopping without leaving our homes,which makes the life more convenient. Maybe we will also do some shopping and work at home.

And I'm sure there'll be more educational programmes on the radio or TV or by the Intemet or videophones,so perhaps some children won't need to go to school every day. They'll study at home.

In the future,all electric equipment at home is under the con-trol of computers. People can learn about the situation of the house by working on the computer at the office. No people like doing housework. Maybe each family will have a robot. Every day we can tell the robot what to do-shopping,housework and so on. believe the dream will come true some day.

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.
