【答案】1.A2.D3.B4.A

【解析】本文是一篇科普说明文。

文章讲述了新旧电子设备的差别，旧电子设备耗能高，不环保。

所以作者主张使用新电子设备。

1.观点态度题。

根据文章第一段中的That’sbadnewsfortheenvironment—andourwallets—astheseoutdateddevicesconsumemuchmoreenergythantheneweronesthatdothesamethings.可知，使用旧的电子设备对环境和我们的钱包都是坏消息。

这些过时的设备做相同的事情要消耗比新设备更多的能量。

由此推知作者认为新电子设备环保、节能。

故选A。

2.细节理解题。

根据文章第二段中的Tofigureouthowmuchpowerthesedevicesareusing,CallieBabbittandhercolleaguesattheRochesterInstituteofTechnologyinNewYorktrackedtheenvironmentalcostsforeachproductthroughoutitslife可知，Babbitt’steam研究的目的是弄清楚这些设备用了多少电。

故选D。

3.细节理解题。

根据文章最后一段中的Theyfoundthatmoreon-demandentertainmentviewingontabletsinsteadofTVsanddesktopcomputerscouldcutenergyconsumptionby44%.可知，平板电脑是耗能最少的电子设备，可以降低44%的耗能。

故选B。

4.推理判断题。

根据文章的整体内容可知，因为旧的电子设备耗能高，不环保。

所以作者建议停止使用旧的电子设备。

故选A。

B

【答案】5.B6.D7.B8.C9.A

【解析】本文是一篇科普类短文阅读。

文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。

5.推理判断题。

根据文章Foodproduction中叙述了没有经验的人可以用3D打印机做出复杂的巧克力雕塑和美丽的婚礼蛋糕，以及餐厅能够用3D打印出所有的菜肴和甜点，从而可以推断出3D打印的优势是节省了做饭的时间和精力。

故选B。

6.细节理解题。

根据文章第三段Someexpertsbelieveprinterscouldusehydrocolloids（水解胶体）fromplentifulrenewableslikealgae（藻类）andgrasstoreplacethefamiliaringredients（烹饪原料）.可知，3D打印机可以使用可再生材料作为食物来源。

故选D。

7.推理判断题。

根据文章第四段Foodprintingcouldallowconsumerstoprintfoodwithcustomizednutritionalcontent,likevitamins.（食品打印可以让消费者打印定制营养的食物），从而可以推断出3D打印出来的食物可以满足个人营养需求。

故选B。

8.细节理解题。

根据文章最后一段mostofthe3Dfoodprintersnowarerestrictedtodryingredients,becausemeatandmilkproductsmayeasilygobad.可知，阻止3D打印食物进一步广泛使用的原因是原料必须是干的，含水多的肉和牛奶不能应用于3D打印因为很容易坏。

故选C。

9.主旨大意题。

文章主要介绍了3D打印技术在食物上的应用取得了进展，但目前仍面临着许多方面的挑战。

所以用标题3DFoodPrinting:

DeliciousNewTechnology，故选A。
