　　The lecture apparently disproves what is argued in the reading material. According to the passage, the formation of a mountain range could have three possible explanations: underground hotspot, plate squeezing, or the ice place. However, the professor in the lecture asserts that a closer scrutiny of this argument would reveal how flimsy it is. He then represents several evidences to demonstrate his statement.

　　To begin with, supposition given by the author states that … But the professor claims that the reading passage fails to take into account that if the mountain is really formed by hotspot, then we should find at least one hotspot nearby, however noun was found. Therefore, the assertion of the author seems too absurd on the basis of this fundamental truth.

　　Furthermore, the passage assumes that …The professor, however, suggests that this assumption may not be merited by the evidence. Say, if the mountain is really formed by plate squeezing, then by now it should looks seriously erosion, and less tall and sharp. This contradiction is obvious here when the mountain in fact is younger and taller than they should be. On account of these point the professor explicitly refutes the reading passage.

　　Last but not the least, the passage may be right about the emergence of a certain valley, but one critical fact is left out of the consideration. Pointed out by the professor, the truth is that the valley are formed along the rivers, however the mountain should have been existed before the frozen of water happened. That is to say, the mountain cannot be formed by ice. Based on above-mentioned grave problems, the assertion of the author turned out to be a preposterous idea.

　　In conclusion, taking account of the arguments offered above, the lecture clearly identifies the defects of the reading material and forcefully showed that the explanations given by the author are utter nonsense.
