21、anguage (身势语)”“fictions (小说)”均不在此列。4答案与解析：B推理判断题。由最后一段的后半部分尤其是“Inthisarticle, well.”可以看出，该文是一篇文章的引言，用来吸引读者，介绍文章的内容。B【语篇解读】本文是一篇说明文。主要讲述了为了帮助宇航员在太空解决严重的皮肤烧伤或骨折的问题，来自德累斯顿理工大学(TUD)的科学家开发了一种能够在太空中产生人体组织的3D生物打印机。5答案与解析：D细节理解题。根据第二段的“3Dbioprintersaresimilartotraditional3Dprinterswithonekeydifference.Inste
22、adofcreatingobjectsfrommaterialslikeplastic, .”可知，这款生物打印机与传统的区别在于：打印的原材料不同。故选D项。6答案与解析：A细节理解题。根据第三段的“Thebiggestisfindingcellstocultivateandcreatetherequiredbioink.”可知，在太空使用生物打印机的最大困难是怎么找到打印原材料。故选A项。7答案与解析：B词义猜测题。根据第四段中“Usingbiomaterialfromtheastronautsthemselvesalsoeliminatestheriskoftransplantrejec
23、tion.”可知，此处是说用宇航员自己的生物材料也可以消除排异的风险。故选B项。8答案与解析：B推理判断题。根据最后一段的“Instead, a3Dbioprintingcapabilitywillletthemrespondtomedicalemergenciesastheyarise.”可推知，TommasoGhidini对于3D生物打印机是很赞同的。故选B项。.七选五【语篇解读】本文主要阐述了谚语“Hewholaughslastlaughsbest. (笑到最后的人才笑得最好)”，并通过ZacEfron的故事进行说明。【高频词汇】1.promotev.促进；推销2.graduatefro
