“进化”不了的爱

孙君飞

进化论包含着残酷的丛林法则,也隐含着生命的自私自利性。一个生命个体要想很好地生存下去,必须要将自己变得更优秀,学会“排他”,否则优胜劣汰的只能是自己。不过,人们在观察工蜂时,惊讶地发现,它们并未受到进化论的影响,它们混沌若当初,或者说它们完美地保持着一种纯粹而崇高的精神,这使它们成为生命进化中的另类。

工蜂属于生殖器官发育不完善的雌性蜂,即便能够产卵,也只是没有受精的卵,因此它们自身没有繁殖能力。这种缺陷可怕而又不幸,然而工蜂对此无动于衷,甘愿终身携带着缺陷而生,从未奢望将自身进化得更完美更强悍。值得称道的是,工蜂的适应性反而很强大,它们拥有相当厉害的武器——毒刺,刺上长有倒钩,一旦“亮剑”就不能回收利用。工蜂的毒刺是不折不扣的双刃剑,在伤及侵害者的同时,自己的生命也面临着终结。

蜜蜂家族中令人难以置信的社会结构更加震惊着世人的心灵,在这里一切都那么井然有序,合乎“法则”,一切又那么一往情深,合乎“生命之爱”。蜜蜂的利他主义行为也许会让达尔文难以理解,失去繁殖能力却能够将各种特征和习性一代代传承下去的工蜂可能更让达尔文目瞪口呆吧。答案其实很简单,一切都源于蜜蜂与众不同的遗传结构。换言之,存在于工蜂体内的遗传基因极其顽强,只有它们才会驱使工蜂去鞠躬尽瘁地照顾其它跟自己具有相同基因的生命,甚至为对方牺牲自己,却无怨无悔。

蜂后产下的受精卵天生高贵,常常会孵化出雌性幼蜂,而延续高贵的办法只有一个:它们只有食用了工蜂分泌的蜂王浆之后,才能发育成具有生殖能力的小蜂后,否则它们在长大后依然属于工蜂——从出生时开始,便将生命献给蜂群、终日辛劳的工蜂!

由于小蜂后的基因与工蜂的基因几乎相同,从身形外貌上看,彼此也几乎一模一样,这也许使工蜂顿感一阵甜蜜而幸福、神圣而自豪的恍然:站在我面前的,莫不是又一个“我”?我由此获得了新生,得到了永恒……工蜂在含辛茹苦喂养小蜂后的过程中,彼此的血缘关系升至最亲密最牢固。它们原本不是毫不相关的两个,而是见证生命延续、利他友爱的两个。因为相同的基因存活在它们的生命之中,工蜂在潜意识里将蜂后看得比自己的生命更为重要,为了对方、也为了另一个“我”和“我们”,它们可以在必要时完全放弃自己现实的生命及其未来。

(选自在《思维与智慧》有删节)

下列关于“工蜂”的表述,不符合原文意思的一项是

  A.作为生命个体,工蜂的生命隐含着自私自利性,要想不被淘汰,它必须将自己变得更优秀,学会“排他”。   

  B.工蜂之所以成为生命进化中的另类,是因为它们完美地保持着一种纯粹而崇高的精神,并未受到进化论的影响。   

  C.工蜂的适应性很强,尾部长有倒钩的毒刺是相当厉害的武器,在伤及侵害者的同时,工蜂的生命也意味着终结。   

  D.从出生开始,就为蜂群而终日辛劳的工蜂,能把各种特征和习性一代代传承下去,靠的是与众不同的遗传结构。

下列有关“蜜蜂繁殖"的表述,符合原文意思的一项是

  A.蜂后是具有生殖能力的雌性蜂,产下的受精卵天生高贵,孵化出雌性幼蜂,幼蜂长大以后就成为新一代蜂后。

  B.工蜂自身没有繁殖能力,属于生殖器官发育不完善的雌性蜂,即便能够产卵,也只是没有受精的卵,不能孵化幼蜂。

  C.存在于工蜂体内的遗传基因极其顽强,它驱使工蜂分泌蜂王浆,鞠躬尽瘁地照顾和自己具有相同基因的“孩子”。

  D.蜂后负责产卵,工蜂负责喂养幼蜂,因而小蜂后的基因与工蜂的基因几乎相同,身形外貌上也几乎一模一样。

下列根据原文信息所作的推断,不正确的一项是

  A.采粉、酿蜜、饲喂幼虫的工蜂是蜂群的主体,儿歌唱的“小蜜蜂,整天忙,采花蜜,酿蜜糖”,指的就是工蜂。

  B.蜜蜂家族一切都井然有序,合乎“法则”,合乎“生命之爱”,人类如果借鉴了这种社会结构.可能会更有利于社会和谐。

  C.为了蜂后和后代,工蜂不惜牺牲自己,是因为它们有奉献精神,潜意识里将蜂后和后代看得比自己的生命更重要。

  D.工蜂一生从事的是利他的事业,而不是优化自己的结构来繁衍后代,从这一点来看,    达尔文的进化论“适者生存”不科学。

F. Stop Expecting Everything to Be Perfect

How to Simplify Your Life

Less is more. This is why we say: reduce things by half instead of doubling them, get rid of junk instead of piling it up, relax instead of stressing, slow down instead of speeding up. Apply these principles in your everyday life in a conscious way. You will then find yourself well along on your journey to simplification.

61.__________

When you concentrate on one task, you find you have energy that you didn't even know you had. Just imagine: you are at a fair and you have to carry two heavy pigs over 100 yards. If you keep grabbing one and then the other, it will take forever, because one of them will keep slipping out from under your arm and running off. But if you tie one pig in a place, pick up the other, gather all your strength and make a dash for the finish line, pause for a moment, run back and get the other one, and with great determination, carry the second pig to the finish line, then you can be sure of success.

62._________

The pressure at work is on the increase in all occupations. In the modern nuclear family, the expectations that formerly would have been shared among all the relatives are now concentrated on the individual partner.

If you have the feeling that 24 hours per day are not enough for all the things you need to do, then it's not because the day has too few hours, but because you have too many activities. A simple fact that overloaded people often tend to be forgot. The solution is equally simple: refuse to accept so many work assignments in your private life or your working life.

63.________

“I can handle stress” is regarded as a positive statement in the world of work. People who can handle stress are given more and more to cope with -- until one day they break.

Pay careful attention to the signs that tell you that you are under more stress than you can cope with. These signals can come from various areas of life. You become ill, or your work efficiency decreases.

If you have any of these symptoms, change your life goals and decrease your tolerance of stress. Say quite openly, “I can't manage that.”

64.__________

“If only I were slimmer, more beautiful, richer, cleverer, then I would be happier.” This is a dream that makes a lot of people ill, depressed, and unhappy. Life has its flaws, defects, corners, and edges. Only those who accept this reality can lead a really full life.

Of course there are activities in which errors are dangerous: driving a car; crossing the road. But life doesn’t consist entirely of these things. In/Among them there is a lot of room for small and large mistakes.

65._________

Successful people all have their own places where they can withdraw in order to work. Find out which places improve your creativity. For me it’s the train. When I know that I’m going to be traveling for four hours without phone calls and people knocking on my door, I find my mind is free and I can read or write complex articles. There can be problems working on the train, of course: if the person sitting opposite you keeps talking away, or if train trips make you tired (some people fall asleep after a few miles).

A. Kripke’s Research Tool

B. Dangers of Habitual Shortages of Sleep

C. Classification of Sleep Problems

D. A Way of Overcoming Insomnia

E. Sleep Problems of Long and Short Sleepers

F. Oversleeping — Too Much of a Good Thing

1. ______

Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences.

2. ______

Investigators at the University of California in San Diego found that people who clock up 9 or 10 hours each weeknight appear to have more trouble falling and staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep and feeling refreshed after a night’s sleep than 8-hour sleepers.

3. ______

Previous studies have shown the potential dangers of chronic(慢性的) shortages of sleep — for instance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.

4. ______

For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how mush they slept during the week and whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning and being unable to fall back to sleep, and having tiredness interfere with day-to-day functioning.

5. ______

Kripke found that people who slept between 9 and 10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bed. “It stands to reason that if a person spends too long a time in bed, then they’ll spend a higher percentage of time awake,” he said.
