1 @8 V5 d3 U/ p0 J! c1 ~A: But you do care about dinosaurs I recall (every class) and today we discuss (about) the geological evidence about what may have killed off the dinosaurs at least here (till) in North America.$ j6 A- ?% \% i) e6 c" V! h9 Z

) ^( D0 t7 o$ Y6 lA: Oh, well, yeah. About 60 million years ago, a huge comet (comic) did crash (pression) into (the) earth down in Mexico, and it plowed out as an enormous (plaud up this norms) crater over a hundred miles (they) across. l" A% ?- J0 p# g4 e, y
B: And that’s what why death the (they defy dying) dinosaurs, right?8 l+ D3 R' I( o0 l! F2 C
A: Well, it was not exactly the impact itself, but what happened right afterward (were). you see researchers figured out from the shape of the crater that the comet (comment) must be coming in pretty low across the Atlantic. And so right after the impact a huge cloud of fire river must have (that) swept clear across the North America. All (arrange) in a few minutes, and that was probably killed off not just dinosaurs but a lot of different species of plants and animals.

A: Yeah, And even (I need) two thousand miles from the impact, plants would have been burst in the flames (flare).

A: Make sense. Anyhow, later on the tons (tone) of (the) dusts that (have) thrown away out into (up) the atmosphere may have caused some global climate change, so eventually, the comet probably affected plants and animals species all around the world, but nowhere as much as North America.
