“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。

阅读下列应用文及相关信息,并按照要求匹配信息。请在答题卡上将对应题号的相应选项字母涂黑。注意:如选E请填涂AB;选F请填涂CD.

以下是一些新闻报道的信息:

A. Science magazine published the study about orangutans. The scientists collected evidence from years of observations in six areas on Borneo and Sumatra. The scientists found that the animals demonstrated a total of twenty-four signs of cultural activity. Several actions were demonstrated in some orangutan groups, but not others.

B. The Environmental Investigation Agency and Telapak released the report. Telapak is an environmental group based in Indonesia. The Environmental Investigation Agency operates in several countries. The two groups say Indonesia controls ten percent of the world's tropical rainforests.

C. Richard Sandor is the chairman of the C-C-X. He praised the companies forming the group for demonstrating leadership. He said they believe that an active way to deal with global warning helps everyone. The group said its members want to reduce costs they may face from future rules on greenhouse gas emissions. Trading credits may help businesses find the most effective methods to reduce pollution. Members also hope to improve their public image on environmental issues.

D. Their most detailed effort involved ninety-nine kinds of birds, insects and plants in North America and Europe. They found that the territory where these plants and animals live has moved north by an average of six kilometers every ten years. In Europe, some butterflies now live as much as one hundred kilometers to the north because of changes linked to higher temperatures.

E. The new report says many areas experienced unusual weather in two thousand and two. Most of Asia, for example, was warmer than usual. India had unusually high temperatures in April and May. The extremely hot weather caused hundreds of deaths. There also were extremely dry conditions across India. Parts of Africa experienced unusual heavy rains. Yet other areas in Africa had unusual dry weather.

F. Hydrogen is the most common element in the universe. Hydrogen is a colorless gas. On Earth, it is present in large amounts in natural gas, coal, plants and water. By weight, hydrogen produces the highest energy levels of any known fuel. When burned in an engine, hydrogen releases no harmful pollution into the environment. When powering a fuel cell, the only waste is water. However, hydrogen氢 is difficult to store. It also burns easily.

  请阅读以下与新闻信息,然后匹配与上面新闻相关的报道内容:

A severe ocean storm hit South Korea in August. It set a new national record for rainfall. In central Europe, more than one hundred people died in flooding caused by heavy rainfall in September. The flooding also resulted in thousands of millions of dollars in property damage. Yet large parts of North and South America had extremely dry weather.

One member of the Chicago Climate Exchange is American Electric Power. It's the biggest owner of electric power producers in the United States. Company officials say they hope their company's membership will demonstrate证明 the ability of the C-C-X to grow.

For example, members of some groups make a kissing noise by tightening their mouths and sucking in air. Some groups use leaves to clean themselves or protect their hands from sharp objects. The scientists found that some of the animals use sticks as tools to remove insects from holes in trees. Other orangutans猩猩 use leaves to crush insects or gather water.

Professors Parmesan and Yohe used similar methods to examine one hundred and seventy-two kinds of wildlife. They examined the timing of events in the spring, such as the appearance of flowers and the reproduction繁殖 of animals. They found that these events happened an average of two days earlier than normal every ten years.

They say illegal operations to remove trees are causing large areas of forest to disappear. Environmental Investigation Agency director Dave Currey says the illegal operations are completely out of control.

Finding summer jobs for teenagers has not always been easy, but now you no longer have to worry about what your kid can do to earn their own money. Recently I found some different sites online that offer information about what kids can do. Below is some of that information, along with questions to think about to help you come up with your own ideas.
Ideas for summer work: 
● Parks and Recreation Programs.
● Babysitting (当临时保姆) during the day of school.
● Working part-time at a day care for the summer.
● Car washing.
● Working at local vegetable stands.
The easiest way for you to find ways for your child to make money is to think about others’ inconveniences (不方便). Think of things you need done, or would like to have done, and what you would consider paying for these things to get done. Once you have some ideas, you can sit down with your child and talk to them about what they would be interested in doing. Then once you have an idea of what they want to do you can help them come up with fair prices.
Preferably you would want to only have your child working with people you know and trust, or in the least bit you could have your child pick a partner. That way with each of them carrying cell phones, even those without service can call 911, they will be much safer.
