分析 本文是說明文,本文通過舉例說明了太空生活的奇妙,在太空睡覺時(shí),對(duì)宇航員來說主要的挑戰(zhàn)在于恰當(dāng)?shù)乃咦藙?shì);宇航員在一個(gè)地方運(yùn)動(dòng)久了會(huì)出現(xiàn)碳毒性頭痛,宇航員的大腦接收到矛盾的信息時(shí)會(huì)感到惡心.最后告訴我們美國國家宇航局對(duì)宇航員主要的擔(dān)心是宇航員回家后的修養(yǎng)期和任何在太空長(zhǎng)久地保持健康.
解答 63.A 細(xì)節(jié)理解題.根據(jù)第二段第一、二句"First consider something as simple as sleep.Its position presents itsown challenges."可知在太空睡覺時(shí),對(duì)宇航員來說主要的挑戰(zhàn)在于恰當(dāng)?shù)乃咦藙?shì).故選A項(xiàng).
64.C 細(xì)節(jié)理解題.根據(jù)第三段中"But station residents have to be careful aboutstaying in one place too long.…You can end up with what astronauts call acarbon-dioxide headache"可知宇航員在一個(gè)地方運(yùn)動(dòng)久了會(huì)出現(xiàn)碳毒性頭痛.故選C項(xiàng).
65.D 細(xì)節(jié)理解題.根據(jù)第四段中"Your inner ear thinks you're failing.Meanwhileyour eyes are telling you you're standing straight.That can be annoying-that'swhy some people feel sick."可知宇航員在大腦接收到矛盾的信息時(shí)會(huì)感到惡心.故選D項(xiàng).
66.B 細(xì)節(jié)理解題.根據(jù)最后一段倒數(shù)第一、二句"The focus on fitness is as much about science andthe future as is about keeping any individual astronaut healthy…NASA is worriedabout two things:…and,more importantly,how maintain strength and fitness…"可知美國國家宇航局對(duì)宇航員主要的擔(dān)心之一是如何在太空長(zhǎng)久地保持健康.故選B項(xiàng).
點(diǎn)評(píng) 解答細(xì)節(jié)理解題時(shí),一個(gè)常用的方法就是運(yùn)用定位法,即根據(jù)題干和選項(xiàng)中的關(guān)鍵詞從原文中找到相關(guān)的句子,與選項(xiàng)進(jìn)行比較從而確定答案;推理判斷題既要求學(xué)生透過文章表面文字信息推測(cè)文章隱含意思,又要求學(xué)生對(duì)作者的態(tài)度、意圖及文章細(xì)節(jié)的發(fā)展作正確的推理判斷,力求從作者的角度去考慮,不要固守自己的看法或觀點(diǎn).
