①有这么一家公司，经营一种叫“替人读书”的业务，把几百页的大部头著作精简成10页左右的“精华”，提供给那些想诿书而没有时间读书的人，并获取高额报酬。这个公司一时间十分受欢迎，它提供的“精华”摘要，犹如一粒小小的营养胶囊，让人们心理上觉得获得了所有需要的信息和养分，同时大大节约了时间。

②这套办法是没法用在文学和哲学书上的吧，否则《安娜·卡列尼娜》的摘要精华，就是一句“已婚的安娜爱上了渥伦斯基，离开了家庭，然后卧轨自杀”，而《简·爱》的摘要就是“家庭教师简·爱在罗切斯特先生家里教书，后来嫁给了他”，而《西游记》的摘要就是“                         ”。如果抽去了这些故事的细节，抽去了一切社会属性和事情发展的时间性，没有一个故事值得一读，没有一个人物值得去爱。好作品是无法压缩成所谓的精华的，真正能够回馈至生命本身的阅读必须付出时间和精力。

③以获取信息为目的的阅读，或许可以压缩成“精华”，让无暇与心灵对话的读者迅速吞咽，立即获得营养。这是兔子吃胡萝卜式的阅读，是占有性的阅读。另外一种阅读，是更从容的阅读。这样的阅读考验读者的情趣，也试探读者的耐心。在这种阅读中，读者和书中的内容建立起了生命的联系，获得了思维能力和感情容量的增强，找到了阅读的意义，生命因此而丰富起来。

④读书是个选择。读书的目的不仅仅是获得知识，还是选择如何度过这一段生命时光。或许在个节奏加快的世界里，选择读书本身就是一件奢侈的事情。获得信息和知识，在这个互联网时代是容易的，而取得思维能力的增强和理解力的增加是有难度的。当网络渐渐分担甚至取代了图书传播信息和知识的功能时，滋养心灵成了书藉更重要的功能。那些不可压缩的是什么？那些不能变成“精华摘要”的是什么？这是每一个写书人和读书人值得思考的问题。

⑤这个时代盛产各种各样的营养胶囊，一粒玫瑰胶囊或许有助于皮肤保养，而一朵盛开的红玫瑰可以召唤整个春天。（《选自《人民文摘》，有删改）

Look into hunters' eyes

    Have you ever been face to face with a cat or a sheep? If you have,you probably noticed that cats narrow their eyes to vertical (垂直的) slits (狭缝),while sheep have horizontal pupils (瞳孔).

     Why is the difference?

    Scientists from the Universities of California Berkeley and Durham in Britain may have the answer. Their research, published recently in the journal Science Advances, suggested that pupils' shapes could tell whether an animal is a hunter or gets hunted.

    The researchers took a close look at the eyes of 214 land animals.The challenge was to see if they could find a relationship between an animal's role in the food chain and the pupils' shapes.

    They found a pattern. Species with pupils that are vertical slits are more likely to be small ambush predators (捕猎者) – creatures that lie in wait for their lunch.In contrast,those with horizontal pupils are more likely to be plant-eating prey (猎物) species.

    Evolution chose the arrangement for a good reason.For hunters such as household cats,it appears that vertical pupils not only improve their ability to keep track of moving objects like mice,but also maximize (使最大化) their ability to judge the distances of the animals they hunt.

    However, an interesting discovery from the study is that the slit pupils are mostly linked to hunters that are close to the ground. Therefore, bigger cats who actively hunt down their prey, like tigers and lions, don't have slit pupils.

    On the other hand, for plant-eating prey animals, horizontal pupils give them a wider field of vision.When stretched (伸展) horizontally,the pupils allow for more light to enter from the front, back, and sides. Meanwhile, they also limit the amount of light from the sun above so the animal can see the ground better.“ Once they do find a predator,they need to see where they are running,” said leading researcher Martin Banks,a UC Berkeley professor of optometry (视光学).“They have to see well enough out of the corner of their eye to run quickly and jump over things.”

    But what happens when they bend down to eat? Researchers checked this by watching prey animals in the Oakland Zoo in California, US. They believe that when goats lower their heads to eat,their eyes rotate (旋转) to keep their pupils horizontal.

    So it seems that the eyes are indeed the window to the soul!
