A.将果实从树上摘下来

B.保护环境,减小对环境的依赖

C.将前肢解放出来,使用工具

D.扩大活动范围,利于生存

答案

法国博物学家居维叶说:正是人的直立行走,使头颅免受地球引力妨害,为大脑发育提供了广阔空间,使人的大脑因在各个方向上的自由扩展而比较其它动物的头颅更加接近地球,使得头的面积和脑的面积达到最大比例,使人的大脑具有最智慧的认知结构和思维潜质.正是直立的身体,使人的感官产生最大效用.使人的眼睛能够“高瞻远瞩”,能够随着转动的脖颈自由的巡视四周;使两耳能够听到来自各个方面的声音,与眼睛一起坐到“眼观六路.耳听八方”;使人的触觉能够感受到最滋味的刺激.触摸.暗示和各种难以表达与述说的情感和爱.恩格斯曾指出,直立行走是从猿到人转变过程中“具有决定意义的一步”.古猿的直立行走造成了前后肢的分工,直立行走使古人类能够将前肢解放出来,使用工具.前肢所从事的活动越来越多,上肢更加灵巧.

故选:C.

     As a boy growing up in India,I had longed to travel abroad.I used to listen to the stories my father

would tell me about his stay in Canada and tours to Europe in the 1970s,with great interest.

My big moment finally came in the summer of 1998 when I was able to accompany my parents to

Europe,where my father was to attend a meeting.We planned to travel to Belgium,Netherlands and

West Germany.

     I have vivid memories even today of going to Mumbai airport at night all excited about finally going

abroad.I had heard several great things about Lufthansa till then but now I finally got to experience them

first hand,during the flight to Frankfurt.We flew business class and even today I can remember the

excellent service by the Lufthansa crew.The flight was really smooth and thoroughly enjoyable,even for

someone like me,who is otherwise scared of flying.

     After spending almost two weeks in Europe,we took the Lufthansa airport express from Dusseldorf

to Frankfurt airport,for our return flight.What a journey that was! All along the Rhine (莱茵河),it was

simply an unforgettable experience.I was in a sombre mood on the flight back to Mumbai as it marked

the end of a wonderful vacation,but the Lufthansa crew members were able to change it into a most

enjoyable experience yet again,with the quality of their service.

     Being the first airline to take me overseas,Lufthansa will always hold a special place in my heart.

Even today,I continue to enjoy flights on Lufthansa and simply cannot dream of choosing any other

airline.Flying,in general,for me,has always been an ordeal (terrible and painful eperience). Flying on

Lufthansa,however,is something I always have and always will look forward to.
