当宇航员乘坐宇宙飞船飞向天空时，必须从生物圈中携带维持生命所必需的物质．你认为应该携带哪些物质呢？．
在飞向太空时，必须携带维持生命的物质，太空是一个高真空的环境，没有空气，温度也很低，因此宇航员必须携带人呼吸所必须的氧气以及穿戴维持适宜温度的宇航服，在细胞的线粒体里，在氧的作用下分解有机物释放能量供人体进行各项生命活动，所以必须有营养物质．氧气和营养物质的运输都必需在水中进行，水是构成细胞的主要成分，因此还必需携带水分．
故答案为：宇航员必需携带氧气、营养物质和水，以及维持适宜温度的宇航服等装置．
| Elle Woods has it all. She’s the president of her sorority, a Hawaiian Tropic girl, Miss June in her campus calendar, and, above all, a natural blonde. She dates the cutest fraternity boy on campus and wants nothing more than to be Mrs. Warner Huntington Ⅲ. But, there’s just one thing stopping Warner from popping the question: Elle is too blonde. Growing up across the street from Aaron Spelling might mean something in LA, but nothing to Warner’s East-Coast blue blood family. So, when Warner packs up for Harvard Law and reunites with an old sweetheart from prep school, Elle rallies all her resources and gets into Harvard, determined to win him back. But law school is a far cry from the comforts of her poolside and the mall. Elle must wage the battle of her life, for her guy, for herself and for ail the blondes who suffer endless indignities every day. "Legally Blonde" is an American comedy which was released in 2001 wordwide. The heroine is played by Reese Witherspoon, who does well in the movie. In my opinion, strictly, "Legally Blonde" is a not-so-bright comedy. Why The combination of a beautiful but silly blonde and the strict but dull law school makes inconsistent musical notation. But I am well disposed to the lovely girl at the same time. There are a lot of reasons. For one thing, the outstanding performance of Reese Witherspoon makes a deep impression on my mind. For another, the magic and special character of the heroine Elle moves me. She is sensitive to fashion and good at making up, but not the silly Billy. Her perfect observation also lights up our eyes. When she went to visit the prisoner, with a CalvinKlein blouse, a suit of Clinique and the last Cosmo, who could doubt her ability to get the trust When she won the case by her experience about her life, nobody could deny that sometimes a handful of common sense was worth a bushel of learning. |
