36、人生活在贫困线以下时,国家在太空计划上投资数十亿美元是否有意义?)”可知,人们问这个问题是想知道太空计划是否有益于地球上的人们。故选 D。2.A推理判断题。根据第二段中的“It affects almost only boys (它几乎只影响男孩)”可知女孩似乎不会得这种病。故选 A。由第二段中的 However,according to astudy conducted by the Japan Aerospace Exploration Agency (JAXA) on theInternational Space Station (ISS).which allows for target
37、ed drugs 可知晶体蛋白的形成是关键,而非 ISS,排除 B 项;还是由第二段中的 crystalline protein structuresform regularly in microgravity(微重力) conditions, which allows for targeted drugs可知在微重力条件下,这种病并不会变得严重,排除 C 项;由第二段中的“Theyrewheelchair-bound by age 12”可知,D 项错误。3.B推理判断题。根据第三段中的“And you want to talk about feeding thehungry.which m
38、eans you can make a lot of lettuces in space.(你想谈谈喂养饥饿的人吗?我们有太空生菜,它的结构和营养相当于地球上的生菜。太空里几乎什么都有,这意味着你可以在太空制造很多生菜。 )”可知作者对在太空中种植食物的态度是赞同的,故选 B。4.B推理判断题。根据第一段可知许多人提出一个问题,作者几乎厌倦了回答;第二段就杜氏肌肉营养不良症做出解释,第三段就为饥饿者提供食物做出解释,第四段是一个简短的总结,同时也是作者对于第一段提到的问题给出的一个答案。所以该篇文章是摘自一个问问题和给出优质答案的网站。故选 B。.语篇解读本文是一篇说明文。文章主要介绍了宇航员
39、在太空种植植物的原因和好处以及种植方法。1.D根据空后“Because of this, its not practical to send everything needed for along journey, only to be used once and thrown away.”可知,把长途旅行所需要的东西都送出去,只用一次就扔掉是不现实的。 此处应介绍空后一句的原因,故 D 项“将任何物体带入太空的成本约为每公斤 22,000 美元。”符合语境。2.F根据空前一句可知植物可以为宇航员提供新鲜的东西。根据空后一句可知,植物可以帮助改善空气质量,因为它们可以产生氧气。据此可知,空处应
40、是介绍在太空种植植物的好处,且承接上文,即宇航员将欢迎在他们的干粮中加入水果和蔬菜,故选 F。3.B上文介绍了太空种植的好处,即为宇航员提供新鲜的果蔬、改善太空站的空气质量等,结合下文可知,在太空种植果蔬有一定的困难,据此可知,空处承上启下,与上文形成转折关系,故 B 项“然而,在太空种植植物也有挑战。”符合语境。4.E根据上文可知,在失重的情况下,植物的根和叶不知道如何生长,水分也不容易从根部传到叶子上;而空后一句介绍了解决土壤问题的办法;据此可推知,空处应是介绍解决上述问题的方法,故 E 项“(目前)正在开发专门的容器来帮助植物正确生长。”符合语境。5.C根据空前一句可知,科学家们正在寻找
41、各种让植物少用水和光,在太空快速生长,而且可以抵抗病害的方法;且下文又提到改良后的植物对地球的影响;据此可推知,空处应是说明这些方法会反过来给地球带来改善,故选 C。.One possible version:Paragraph 1:One evening, my uncle came, and my dad wanted to show him Peepers loop.When he cleaned Peepers droppings as he always did, Peeper ruffled up his feathersand spread the powerful wings.
42、Standing beside him, I could feel the wind from wingbeats.
