人的身体就好比一台机器,机器缺了油就会停止运转,人的身体如果没有维生素及蛋白质、脂肪、糖、钙、磷、铁等多种营养元素来源源不断补充,就难以生存。当然,上述的营养元素大部分可以从鸡、鱼、肉、蛋或水果中得到,可是从我们目前的生活水平来看,人体需要的维生素主要还是来自蔬菜。
什么叫蔬菜呢?简单地说,蔬菜就是可以做菜吃的草本植物。它以十字花科和葫芦科的植物居多。我们常吃的,如白菜、菠菜、芹菜、胡萝卜、黄瓜、辣椒、西红柿等,统称之为蔬菜。它们都含有丰富的营养,但又有各自的特点--各种维生素的含量不同,就胡萝卜素来说,同样都是100克蔬菜,菠菜含有3.87毫克,胡萝卜含有3.67毫克,鲜蒜头则是空白。
我们在日常生活中,不但要多吃蔬菜,更需要了解它们。这是因为人体一旦少了某一种营养元素,就会导致疾病的发生。你有贫病吗?请经常食用菠菜,因为菠菜含有不少的维生素B6,而维生素B6可以起到医治贫病的作用。此外,它还含有为数不少的其他维生素B以及钙、磷等营养成分。你的胃口不佳,食欲减退吗?就请食用适量的鲜蒜头,因为它含有维生素B1。据介绍,每100克的鲜蒜头就有0.24毫克的维生素B1,而它的功能是帮助消化的。因此,适当地吃些鲜蒜头就可以增加食欲。你想使自己的伤口尽快愈合吗?请适量地吃些辣椒。因为辣椒含有数量惊人的维生素C.据科学统计,每100克的辣椒就含有185毫克的维生素C,它比其他蔬菜的含量要多好几倍。你患有夜盲症或干眼吗?就请常吃些胡萝卜。因为它含有比较多的胡萝卜素,而胡萝卜素在人体这个特定的环境中,可转化成维生素A,这对夜盲症、干眼病有很好的疗效。以上这些都说明了蔬菜是良药。
古人说:问渠哪得清如许,为有源头活水来。诗句告诉我们,水清,在于有源头活水,同样道理,人体健康,也必须靠多种维生素来补充。因此,即使是一个身体健康的人,在日常生活中也必须尽可能吃多种蔬菜。然而有些人不吃带药味的蔬菜,如芹菜;也有一些人不吃带辣味的,如辣椒;更有一些人不吃带酸味的,如西红柿。另外,还有一些人对合口味的蔬菜,连吃数餐、数日,甚至到吃厌为止。这些都是挑食、偏食的弊病,它不能提供肌体所需的多种维生素,应该尽量克服。
蔬菜是人们一日三餐中不可缺少的,如能食用多样化,那得到的将是健康长寿。
Dear parents,
“You always say that I am naive. In your eyes, I am always the little girl who will never grow up”. This is my favorite song and also the sound from the bottom of my heart. You made me feel so lucky to be your child. But I find our hearts getting further apart as time goes by.
You strictly forbid me to do entertaining activities even if I finished my homework, such as watching TV or playing computer games. Based on this, I couldn’t get any grade less than A. It is said that genius only means hard-working all one’s life. But I think combining exertion is the best way for learning.
The most important thing to me was that I feel frustrated for having few friends to confide in due to your strict rules. I can’t have a play date, participate in a school play or even choose my own extracurricular activities. Who will accept such a boring and troublesome person? I am just an ordinary girl who can’t stand loneliness, so I always feel contradictory.
On the one hand, I’m grateful to have you in my life, to disappoint you was the least I would do. On the other hand, what you asked for me made me felt like a puppet rather than a real person. I appreciated your efforts to pull me away from a self-indulgent life, but your obsessively extravagant strictness has pushed me into an isolated and insensible one. I need a little freedom so that I will concentrate on something I really interested in.
Father and mother, these words were hid in my deep heart for a long time. I love you, and I believe if you change some harsh rules. I will have a wonderful life.
Best wishes.
Yours, daughter

When I came to this strange world by accident, the heart also carries a afraid, with wen run is you with love I meet, your love is I came to this world have received the first gift. How many covered the morning mist, you surprise and incredibly staring at me that WenXiang such as roses of little face, in my mind I meditate on to the my blessings. Early morning sunshine through the window, hazy gently in your face evenly spread on a layer of holy golden.
Love is like the silent running water, exquisite moistens at every point.

You not only living I to raise me, but also teach me the person, the given me knowledge and tao is "who grass-inch heart, reported in the apartments". Daughter with a mind always touched, but only in small to care and considerate, academic work harder in return. Just as weak grass can only add three points for spring green, and repay the natural nourishing; Autumn leaves only to be born for mud, to repay the tree of raising.
I usually very like reading, you never against, but to buy me a lot of books. By now I can put full of books have a bookcase. You again afraid I read many of the eye sight, and broke in bed to buy a lamp that beautiful the lamp that shield an eye.

Have a period of time, the time to practice painting overload I almost collapse, drab repeatedly that I find very boring. Many times, I almost want to go to all the paper I ripped, but then I was able to hold back. Want to come now, drawing not only gave me to understanding of the love, and paint with the fingers of flexible and the development of the brain, the more developed my perseverance will and persistence. Mother, daughter really grateful to you!
Dad, perhaps you rarely like mother like that teach me what, but you can really affect me a lot. You never is so honest, kind, brave, strong, dedication, and can endure hardships and profound knowledge, you use your good quality affects me, always doing my model. Each time talking with you always make me benefit, always make me understand some of the life philosophy, always important to make my in confused when suddenly enlightened.
