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。你有贫血病吗?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可以起到医治贫血病的作用。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。
Do you ever watch movies from other countries? Whenever I do, I think about how similar people really are all around the world. Even though the cultures and languages in those movies are different from mine, people all around the world are alike in their goals and emotions.
One time, I saw a movie made in china that showed parents helping their children with their homework. . My parents helped me the same way. Another time I saw a movie from Argentina. It showed school children playing hide and seek, which is a game I used to play with my friends during recess. Seeing these films demonstrated to me that education is a common goal in every country. Parents want their children to learn so their lives will improve. It also showed me that children in schools everywhere wants to play with their friends. Sometimes the games are similar to ours and sometimes they’re different. Still, they all have the common purpose of fun and learning to work together.
Earning a living is another common goal. I’ve often seen that in movies about other countries. In some countries, people choose their careers from what they like and are good at. In other countries, careers are chosen for them following the traditions of their families. But in every country it seems that people care a great deal about earning a living, and working hard is respected.
Showing people having fun together is always an important part of any movies, no matter what country it comes from. People everywhere want to be entertained, and want to spend time with their families and friends. Different cultures sometimes enjoy different activities, but all cultures enjoy some form of sports, music and dancing.
The movies I’ve seen make it clear to me that no matter the cultural differences between countries, people everywhere have the same basic needs and goals.

Life has its ups and downs, and only true friends always stay around. Like anyone else, I have got many friends. They often help me when I’m in trouble. Especially, when I fail in an examination, they always care for me and encourage me to study harder. Last year, when I was hurt in a basketball game, my friends took me to the nearby hospital at once and look after me by turns. In my eyes, friends are the most precious wealth that one should treasure all his life.
