Listen to part of (the) lecture in an astronomy class, some you of may be familiar with (the) Apollo programs geological studies of the moon during nineteen sixties, but you may not be aware (of) the (extensive{a.多方面的,广泛的}) research <preceded v. {在...之前,优于;领先}> those studies, the work of two early researchers (was) very important in determining the nature of the surface of the moon, back in nineteen ninety two, a geologist named Carlos Gilbert, was challenging the prevailing views about (the) lunar surface, at that time most scientists thought the craters on the moon (had been) created by volcanic action, Gilbert (made) some careful telescopic studies, there (were) no spacecrafts (back then), so telescopes (were) the best way to observe the moon, he concluded that the lunar crater is so uniform (that) they (had to be the result of) the impact of falling bodies such as meteorites, I posted the enlargements (just some) of his drawing on the board, if you compare them to those in your test, you can see that his are amazingly accurate, still, his <contemporaries n.{同时代的人}> rejected his work, fifty years later, a graduate student named Wolf Baldwin reasserted Gilbert's species, he too met the resistance and he left academics to run his family's machinery business, but, he didn't give up his research, he worked alone in his spare time, and <eventually> wrote an <influential> book (called) the face of the moon, a young geologist (who read) it was so inspired (that) he persuaded (NASA) to <incorporated> geology into Apollo missions, well, the Apollo missions eventually <confirmed> most of Baldwin's ideas, which is astonishing, considering that he wasn't a professional scientist.

' W2 P! W9 e$ qListen to a professor talking with his student after class, (this doesn't have) anything to do with the lecture, Dr. Brown, it's just something I was wondering about, I'm always glad to entertain questions, but I want to know is, without (all) our space exploration, (aren't) astronomers concerned that were polluting space, you know with spacecrafts and <satellites>, that is an interesting question, well, first of all, it's important to understand that the space isn't (that pristine{a.原来的,原始的,古时的}) as you might think, more than (a) thousand tons of debris enter the (earth's) atmosphere every single day, what, (the) spacecrafts (don't need) that much <garbage>, no, (but) there are <meteoroids> entering our atmosphere almost <constantly>, you (are) familiar with what (the) moon's surface looks like, right, oh, (but) we don't have all those craters on earth, I don't understand, remember, the dmoon is lack of atmosphere means that even small <meteoroids> make craters, but most the <meteoroid> (that) hit the earth's atmosphere (melt or) break up in the air, (causing) <meteoroid>? the (streaks{n.光线;闪电} of light) we see (is) that <meteoroid> (breaking up), isn't it? yes, and getting back to your question about pollution, that's one way we could (deal with) the debris of <satellites> and spacecraft, the truth is we do have (a lot of orbit) debris, and traveling (at ten to twenty) thousand miles per hour, really, it wouldn't (want to) collide with anything going that fast, (it's a) real danger for spacecraft, but we (could dispose the debris by) simply sending it back into the earth's atmosphere, so the debris (was just) burned (up) in the atmosphere, well, thanks a lot, Dr. Brown.& _; d- k# [/ J. |8 b
