日常生活中，盐是人们不可缺少的调味品，价钱便宜。家家都知道盐是生活必备品，它可以用来腌菜、肉等食品。
盐也可能存于海水、湖水、井水，甚至岩石之中，它的用途也绝不仅是调味品和腌制食品。对于维持人体生命来说，它几乎同空气一样重要，不同的只是人对缺少盐的耐性比缺少空气大得多。
通过查资料，我知道盐对维持人体正常的新陈代谢，保持液体的酸碱平衡有密切的关系，是维持人生命的一种必要条件。人如果连续几天不吃盐，就会体软无力，接着发生种种疾病，日子一长难免亡。由于人们每天都吃盐，所以不易察觉它这个十分重要的作用。
此外，盐还是一种非常好的药物。用蒸馏水加上精制食。盐配制的生理盐水，常常有效地用来抢救失液、失严重的危病人。用它百分之一至二的水溶液喷雾吸入，可以治疗支气管炎。盐溶液可以真当消毒液使用，把盐放在锅内炒成黄色，加入温水喝，能吐出胃中食积痰涎，可以治疗食物中毒。
医学上认为盐是咸味、无毒的一种药品，入药常用。常用盐水嗽口能防止牙齿出，有健康牙齿的作用。另外，盐也能治疗上火引起的口舌起泡。
盐在日常生活中也是有用的：常用盐水洗头，头发不容易发黄、变白、脱落头发，头皮也不发痒；买回来的新衣服，放在盐水中泡一下，对身体有好处。
盐对我们来说是非常有用的`，但是它也有不利的一面：个人每天大约要吃十克盐，如果吃盐太多，反而不好，因为它是由金属元素合成的，盐吃的太多，会加重肾脏的负担，引起疾病。所以，有肾炎的人，应该尽量少吃盐。
总之，盐是一种用途广泛的东西。只要我们正确了解掌握它，盐就能更好地为人类服务。

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.
