青草变牛奶的秘密

当我们每天喝着香喷喷的牛奶时，你想过没有，这些牛奶是怎么来的?

你可能会说，牛奶是从牛身上挤出来的呀。可是牛吃的明明是草，是富含纤维素的食品，为什么会产出高蛋白的牛奶呢?

原来，青草变牛奶，是微生物和它们所分泌的酶的功劳。

自然界存在着各种各样的微生物，它们总是各就各位，在适合它们生长的地方安家落户。

有一些微生物发现，牛的瘤胃是它们生长的乐园，这里不仅有它们喜欢的无氧环境，没有可怕的胃酸，而且总有着取之不尽的食物。于是，这些小家伙纷纷光顾这里，居住下来，分解纤维素是这些小家伙的拿手好戏，因为它们能分泌纤维素酸酶，将纤维素降解，同时释放有机酸，供牛吸收利用。当然，至此，还没有大功告成。

牛还有其他3个胃——网胃、瓣胃和皱胃。被初步消化的纤维素和微生物会一起陆续进入牛的这3个胃，那里是胃蛋白酶的天下。不过，这时那些“功臣”微生物们可就性命难保了。胃蛋白酶太厉害了，它在将草料分解成氨基酸、维生素和其他营养物质供牛制造牛奶的同时，也将微生物一起消化了。

这样看来，牛身体内的这些微生物实在是很了不起，为了帮助牛消化草料，生产制造牛奶的原料，连性命都“不要”了。

我们能喝上牛奶，不仅要感谢牛“吃进去的是草，挤出来的是奶”的这种无私奉献精神，更要感谢牛体内那些微生物的牺牲精神。能分泌纤维素酸酶的微生物不仅生活在牛肚子中，在自然界也是广泛存在的。科学家们想到，自然界有着丰富的纤维素资源，人类却无法利用，如果利用微生物来生产纤维素酸酶，分解自然界的秸秆、树皮、树叶等纤维素，人类就能获得取之不尽、用之不竭的能源和化工原料了。

Does Fame Drive You Crazy?

Although being famous might sound like a dream come true, today’s stars, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world’s attention. Paparazzi (狗仔队) camp outside their homes, cameras ready. Tabloids (小报) publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature.

According to psychologist Christina Villarreal, celebrities — famous people — worry constantly about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. “Over time,” Villarreal says, “they feel separated and alone.”

The phenomenon of tracking celebrities has been around for ages. In the 4th century B.C., painters followed Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his sold-out readings attracted thousands of fans, leading him to complain (抱怨) about his lack of privacy. Tabloids of the 1920s and 1930s ran articles about film-stars in much the same way that modern tabloids and websites do.

Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modern cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their “story” alive forever.

If fame is so troublesome, why aren’t all celebrities running away from it? The answer is that there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping to remote places away from big cities. They focus not on how famous they are but on what they love to do or whatever made them famous in the first place.

Sometimes a few celebrities can get a little justice. Still, even stars who enjoy full justice often complain about how hard their lives are. They are tired of being famous already.
