“進化”不了的愛

孫君飛

進化論包含著殘酷的叢林法則，也隱含著生命的自私自利性。一個生命個體要想很好地生存下去，必須要將自己變得更優秀，學會“排他”，否則優勝劣汰的只能是自己。不過，人們在觀察工蜂時，驚訝地發現，它們并未受到進化論的影響，它們混沌若當初，或者說它們完美地保持著一種純粹而崇高的精神，這使它們成為生命進化中的另類。

工蜂屬于生殖器官發育不完善的雌性蜂，即便能夠產卵，也只是沒有受精的卵，因此它們自身沒有繁殖能力。這種缺陷可怕而又不幸，然而工蜂對此無動于衷，甘愿終身攜帶著缺陷而生，從未奢望將自身進化得更完美更強悍。值得稱道的是，工蜂的適應性反而很強大，它們擁有相當厲害的武器——毒刺，刺上長有倒鉤，一旦“亮劍”就不能回收利用。工蜂的毒刺是不折不扣的雙刃劍，在傷及侵害者的同時，自己的生命也面臨著終結。

蜜蜂家族中令人難以置信的社會結構更加震驚著世人的心靈，在這里一切都那么井然有序，合乎“法則”，一切又那么一往情深，合乎“生命之愛”。蜜蜂的利他主義行為也許會讓達爾文難以理解，失去繁殖能力卻能夠將各種特征和習性一代代傳承下去的工蜂可能更讓達爾文目瞪口呆吧。答案其實很簡單，一切都源于蜜蜂與眾不同的遺傳結構。換言之，存在于工蜂體內的遺傳基因極其頑強，只有它們才會驅使工蜂去鞠躬盡瘁地照顧其它跟自己具有相同基因的生命，甚至為對方犧牲自己，卻無怨無悔。

蜂后產下的受精卵天生高貴，常常會孵化出雌性幼蜂，而延續高貴的辦法只有一個：它們只有食用了工蜂分泌的蜂王漿之后，才能發育成具有生殖能力的小蜂后，否則它們在長大后依然屬于工蜂——從出生時開始，便將生命獻給蜂群、終日辛勞的工蜂！

由于小蜂后的基因與工蜂的基因幾乎相同，從身形外貌上看，彼此也幾乎一模一樣，這也許使工蜂頓感一陣甜蜜而幸福、神圣而自豪的恍然：站在我面前的，莫不是又一個“我”？我由此獲得了新生，得到了永恒……工蜂在含辛茹苦喂養小蜂后的過程中，彼此的血緣關系升至最親密最牢固。它們原本不是毫不相關的兩個，而是見證生命延續、利他友愛的兩個。因為相同的基因存活在它們的生命之中，工蜂在潛意識里將蜂后看得比自己的生命更為重要，為了對方、也為了另一個“我”和“我們”，它們可以在必要時完全放棄自己現實的生命及其未來。

（選自在《思維與智慧》有刪節）

下列關于“工蜂”的表述，不符合原文意思的一項是

  A．作為生命個體，工蜂的生命隱含著自私自利性，要想不被淘汰，它必須將自己變得更優秀，學會“排他”。   

  B．工蜂之所以成為生命進化中的另類，是因為它們完美地保持著一種純粹而崇高的精神，并未受到進化論的影響。   

  C．工蜂的適應性很強，尾部長有倒鉤的毒刺是相當厲害的武器，在傷及侵害者的同時，工蜂的生命也意味著終結。   

  D．從出生開始，就為蜂群而終日辛勞的工蜂，能把各種特征和習性一代代傳承下去，靠的是與眾不同的遺傳結構。

下列有關“蜜蜂繁殖"的表述，符合原文意思的一項是

  A．蜂后是具有生殖能力的雌性蜂，產下的受精卵天生高貴，孵化出雌性幼蜂，幼蜂長大以后就成為新一代蜂后。

  B．工蜂自身沒有繁殖能力，屬于生殖器官發育不完善的雌性蜂，即便能夠產卵，也只是沒有受精的卵，不能孵化幼蜂。

  C．存在于工蜂體內的遺傳基因極其頑強，它驅使工蜂分泌蜂王漿，鞠躬盡瘁地照顧和自己具有相同基因的“孩子”。

  D．蜂后負責產卵，工蜂負責喂養幼蜂，因而小蜂后的基因與工蜂的基因幾乎相同，身形外貌上也幾乎一模一樣。

下列根據原文信息所作的推斷，不正確的一項是

  A．采粉、釀蜜、飼喂幼蟲的工蜂是蜂群的主體，兒歌唱的“小蜜蜂，整天忙，采花蜜，釀蜜糖”，指的就是工蜂。

  B．蜜蜂家族一切都井然有序，合乎“法則”，合乎“生命之愛”，人類如果借鑒了這種社會結構．可能會更有利于社會和諧。

  C．為了蜂后和后代，工蜂不惜犧牲自己，是因為它們有奉獻精神，潛意識里將蜂后和后代看得比自己的生命更重要。

  D．工蜂一生從事的是利他的事業，而不是優化自己的結構來繁衍后代，從這一點來看，    達爾文的進化論“適者生存”不科學。

One day a few years ago we had an uninvited guest—a sparrow.  36  the little bird had flown into our open garage. Then I  37  the bird before I saw it.

“What’s that?”I asked when I first heard the sound.

“It’s coming from the  38  .”my wife, Anita, said. “Maybe it’s one of the little  39  .”

I looked into the garage. No children at all. But there was that sound again, coming from right up there. And that’s  40   I saw the sparrow. It was flying  41  just inches below the ceiling. It was clearly  42  to get out, but couldn’t see the way out was not up, but  43  and and out through the garage door. So the bird continued flapping its wings and bumping its little head 44  the ceiling.

I tried to terrify it out, but only succeeded in driving it into the  45  open space between the door and the ceiling. Then I tried to show the bird how to fly down a few feet  46   it could get outside, but that only seemed to  47  it more.

“Why don’t we just leave for a few minutes,” Anita  48  .“I’m sure he’ll figure it out eventually.”

We went back into the house, where we  49  to hear the ongoing struggle between the sparrow and the ceiling. Then suddenly, it was  50  and our uninvited guest was gone.

I’ve  51  that little sparrow through the years, and I’ve decided that birds are not different much from people. We think we were  52  to fly ever upward, and we don’t even consider the  53  that something good might happen if we just fly down a little bit. Once we figure out that we can make  54  without banging（碰）our heads against ceilings, we can usually save ourselves much  55  .

In Singapore, most of us love window-shopping while some others enjoy having a picnic at East Coast Park or Changi Beach on sunny days. Singaporeans are never bothered by the occasional thunderstorm. However, we know that if it rains for long continuous periods, there will be more serious effects. Just recently the main shopping street of Orchard Road was flooded and some part of Bukit Timah was impassable to traffic. People reacted by writing in to the newspaper to complain about this! We forget that other countries suffer much worse effects. Elsewhere, heavy tropical（熱帶的）storms often result in floods that ruin crops especially in Thailand and Malaysia. This in turn usually means that the price of rice and vegetables here in Singapore will rise because we import these products from them. If there is a typhoon or tsunami, thousands of lives are lost too. This happened in Indonesia and Phuket in Thailand in 2004 and it serves to remind us of how Mother Nature can cause great damage.

Weather patterns in general have changed dramatically in recent years. Scientists believe that global warming and the resulting melting of the polar ice-cap has caused the level of the ocean to rise. This in turn causes flooding of low-lying areas in countries where the land is rather flat and some parts of which is below water level. It is believed that human activities have caused Mother Nature to show her extreme anger, so it is now important that we really work together to cut down on harmful activities, for example, illegal logging（伐木）or irresponsible forest-burning to clear land for farming.

56.From Paragraph 1, we can see that most Singaporeans love________.

A. making complaints           B. going out for picnics

C. doing window-shopping    D. traveling along the coast

【答案】C

【解析】根據第一段第一句可知。

57.What will happen in Singapore if there are floods in its neighboring countries?

A. Heavy tropical storms will follow shortly.

B. The price of rice and vegetables will go up.

C. Many people will write in to the newspaper.

D. More rice and vegetables will be imported.

【答案】B

【解析】根據第一段倒數三，四句可知。熱帶風暴導致的洪水會毀掉莊稼，新加坡的蔬菜和大米是從這些國家進口的，所以會導致蔬菜，大米的價格上升。

58.The underlined word“it” in Paragraph 2 refers to___________.

A. the arrival of heavy tropical storms

B. the import of rice and vegetables

C. the rising price of rice and vegetables

D. the loss of lives in natural disasters

【答案】D

【解析】上句提到臺風和海嘯會導致成千上萬的人死亡。這在2004年在印度尼西亞和泰國的普吉島發生過。自然災害到這人死亡這件事用來提醒我們大自然可以帶來巨大損害。

59.Which of the following shows how the low-lying areas are flooded?

a. global warming

b. the rise in ocean level

c. harmful human activities

d. the flooding of low-lying areas

e. the melting of the polar ice-cap

A. c→a→e→b→d         B. a→c→e→b→d        

C. c→a→b→e→d         D. d→a→c→b→e

【答案】A

【解析】根據最后一段可知。

60.What should we do in order not to make Mother Nature angry?

A. Clear more land for farming.           B. Reduce harmful human activities.

C. Bring down the price of food.          D. Improve the quality of weather.

【答案】B

【解析】根據最后一段It is believed that human activities have caused Mother Nature to show her extreme anger, so it is now important that we really work together to cut down on harmful activities,“人們認為是人類的活動導致了大自然極端憤怒， 因此，現在我們真的應該團結合作減少有害活動。”
