课文内容
Sophie and Ivan are roommates. Ivan is reading the paper.
Sophie: You’re certainly engrossed1 in the technology section. There must be some new, useless, high-tech wonder toys for people to blow millions on.
Ivan: Not exactly. I’m reading about a project that’s been launched by NASA on their international space station Alpha.
Sophie: Talk about throwing money away. If all the money allotted for the space program was spent properly, we could end starvation.
Ivan: Well, that’s exactly what this program is focused on--feeding people.
Sophie: You mean that all the starving astronauts and cosmonauts will finally be able to eat? That’s wonderful!
Ivan: Actually, they’re experimenting with crops that can fight off pestilence2 in inhospitable climates so they can be used down here.
Sophie: Don’t you think it would be more economical to do the testing in Siberia or Canada?
Ivan: Great idea, but the tests can only be run in microgravities set up in the weightlessness of space.
Sophie: Plants in space. American ingenuity3 never ceases to amaze me.
Ivan: Actually, the pioneers in this endeavor4 were Bulgarian scientists. And the first successful space harvest was aboard the Russian space station Mir.
Sophie: Ivan, you’re sounding a bit too smart and it’s scaring me. Could you get back to reading about video games or something?
