阅读下面短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项。
Howe_ver_ex_citing space travel sounds, astronauts must still suffer with bad food．Now, food in space has to be dehydrated（使脱水） or pre﹣cooked and stored．This means astronauts aren't really eating fresh food．
New te_chnolo_gy may change this．Scientific American reports that a specially﹣designed oven will be sent into space this autumn with NASA's NG﹣12 cargo （货物） mission （太空飞行任务）．
Fa_r_from_ the common vacuum﹣packed （真空包装的） meals, astronauts may get to enjoy freshly baked cookies before the end of 2019．
Why aren_'t_the_y baking cookies in space already？ For one thing, there's the risk of a fire．Engineers also have to overcome the challenge of microgravity（微重力）, which prevents heat from circling inside ovens the same way it does on Earth．
Astr_onauts_ will still have to wait a while before they can have their cookies, though．After baking, the results will be sent back to Earth for safety testing．If successful, this will be the first oven to bake food in space．
"I be_lieve__…that will be game﹣changing for both science and astronauts，" food technology researcher Maeena Naman Shafiee told Scientific American．
One of the__main__driving forces behind this project has been NASA's 2018 research into the effects of "confinement（封闭） and isolation（隔离）"．Unlike on the International Space Station（ISS）, astronauts traveling out of Earth's orbit （轨道） may not be able to speak to their loved ones on future missions, which could lead to negative feelings．
It'_s_hope_d that the chance to bake and sense familiar smells can bring joy to crews （宇航人员）．
"Is the ISS _going__to smell like fresh﹣baked cookies？ We don't know，" said NanoRacks' communications manager Abby Dickes．"But that's a feeling we all know and love …that will make someone feel at home．"
Baking__cooki_es in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel．Astronauts have already grown plants aboard the ISS．
With commer_cial_???_商业的） space travel now being planned, who knows what other developments may surprise us in the future？
（1）What can _the_ne_w technology help astronauts to do in space？
A．Enjoy fresh cookies．
B．Store more food．
C．Quickly prepare food．
D．Cook many different kinds of home﹣made meals．
（2）Why is it difficult to bake cookies in space？
A．It's difficult and costly to send food into space．
B．Microgravity stops food from staying in one place．
C．Baking cookies in space would pollute the spaceships．
D．It is hard to heat food properly because of microgravity．
（3）What was the main purpose of the cookie project？
A．To improve astronauts' health．
B．To make improvements in space travel．
C．To encourage more people to travel to space．
D．To make space travel more comfortable for astronauts．2-1-c-n-j-y
【分析】这是一篇说明文．一种特别设计的烤箱有可能让宇航员可以在太空烤饼干，吃上新鲜的食物，从而使太空旅行更舒适．
【解答】（1）A．细节_???è§?é???????????_文章第三段，Far from the common vacuum﹣packed （真空包装的） meals, astronauts may get to enjoy freshly baked cookies before the end of 2019．远不是普通的真空包装的饭，宇航员可能在2019年结束前能享用新鲜烤制的饼干．可知，新技术可以帮助宇航员吃到新鲜的饼干．结合选项，故选A．
（2）D．细节理解题．根据文_???????????????E_ngineers also have to overcome the challenge of microgravity （微重力）, which prevents heat from circling inside ovens the same way it does on Earth．工程师必须克服微重力，它使热量不能像在地球上一样在烤箱内环绕．可知，在太空烤饼干困难的原因是，由于微重力很难适当地加热食物．结合选项，故选D．【出处：21教育名师】
（3）D．推理判断题．根据文章_?????°????????????_It's hoped that the chance to bake and sense familiar smells can bring joy to crews．希望烤饼干的机会和熟悉味道的感觉可以给宇航员带来快乐；及倒数第二段中"Baking cookies in space would mark an important step, offering a small comfort in the difficult and unfamiliar environment of space travel．在太空烤饼干将是重要的一步，在太空旅行的困难和不熟悉环境方面给宇航员提供一些小小的安慰．可知，饼干项目的主要目的是使太空旅行对宇航员来说更舒适．结合选项，故选D．
