(2019·全国卷Ⅱ)Bacteria are an annoying problem for astronauts. The microorganisms (微生物) from our bodies grow uncontrollably on surfaces of the International Space Station, so astronauts spend hours cleaning them up each week. How is NASA overcoming this very tiny big problem? It's turning to a Bunch of high school kids. But not just any kids. It is depending on NASA HUNCH high school classrooms, like the one science teachers Gene Gordon and Donna Himmelberg lead at Fairport High School in Fairport, New York.

HUNCH is designed to connect high school class­rooms with NASA engineers. For the past two years, Gordon's students have been studying ways to kill bacteria in zero gravity, and they think they're close to a solution (解决方案). “We don't give the students any breaks. They have to do it just like NASA engineers，” says Florence Gold, a project manager.

“There are no tests，” Gordon says. “There is no graded homework. There almost are no grades, other than‘Are you working towards your goal？’ Basically, it's ‘I've got to produce this product and then, at the end of the year, present it to NASA.’Engineers come and really do an in­person review, and ... it's not a very nice thing at times. It's a hard business review of your product.”

Gordon says the HUNCH program has an impact  (影响) on college admissions and practical life skills. “These kids are so absorbed in their studies that I just sit back.  I don't teach.” And that annoying bacteria? Gordon says his students are emailing daily with NASA engineers about the problem, readying a workable solution to test in space.

【回答】

13.A　推理判断题。根据第一段第二句可知，来自我们身体的微生物在太空站的表面增长得很快，宇航员每周得花很长时间清理它们，由此断定太空站里的细菌很难清除，故*为A。

14.D　细节理解题。根据第二段第一句可知，HUNCH项目的目的是把学校教育与航天技术联系在一起，故*为D。

15.A　细节理解题。根据第三段最后两句可知，NASA工程师亲自检查那些高中学生的产品，故*为A。

16.B　标题判断题。本文主要介绍了一个项目：把高中的教室教学与太空的研究联系起来，使学生们得到NASA工程师们的指导。因此在选标题时既要有太空，还要有学生，选项B将其完美地结合了起来，故*为B。
