狠拍，最好能提几个好的句型，我觉得自己的句型太单一了...
谢谢大家，辛苦了



The lecture demonstrates thatthe fireball explosion in Tunguska would becaused by the asteroid, which differs from the idea in the reading that theexplosion was the result of swamp gas burning.

Firstly, in the readingmaterial, the author thought that the view of asteroid explosion was notreliable because there was no trace of asteroid near the Tunguska.And he also gave us an example of meteoric explosion where the trace was foundat last. However, the professor of the talk contradicts his points by statingthat owing to the long time passed, the remains of the explosion woulddisappear. So the lack of remains could not be the reason of the swamp gastheory.

Secondly, the passage doubtedthe asteroid theory by saying that there was no crater on the Earth. On thecontrast, the lecture disagrees with the view. The speaker explains that theasteroid may have exploded before impacting with the earth, so there would benot necessarily the crater left.

Finally, the writer told usthat the huge cloud full of methane and air was the main cause. On thecontrary, the professor departs from him by stating that the methane and airwould not concentrate together. At the same time, there are other traces thatsignify the cause of the explosion is more likely to be the asteroid.

So in a word, the readingmaterial supports that the cause of the explosion is the swamp gas, while thelistening material objects it by verifying that it is the asteroid which leadsto the explosion in Tunguska. The ideas in thetwo material are contradictory to each other.

The lecture demonstrates that the fireball explosion in Tunguska would be caused by the asteroid, which differs from the idea in the reading that the explosion was the result of swamp gas burning.

So the lack of remains could not be the reason of the swamp gastheory.


Secondly, the passage doubtedthe asteroid theory by saying that there was no crater on the Earth. On thecontrast, the lecture disagrees with the view. The speaker explains that the asteroid may have exploded before impacting with the earth, so there would be notnecessarily the crater left(no crater left就可以) .


Finally, the writer told usthat the huge cloud full of methane and air was the main cause. On thecontrary, the professor departs from him by stating that the methane and airwould not concentrate together.
