In the listening material, the lecturer explains three points that disagree with what is listed in the reading material.
First, the writer says that the Anasazi may vanish as the result of global warming. It is said in the text that the time Anasazi abandoned was just the beginning of a long-time drought. The lecturer argues that because the drought did not happen on the place the Anasazi lived in and points out certain evidence that proves trees were existed in the area at that time.
Second, the author takes irrigation systems as examples to support that the Anasazi suffered shortages of water. On the contrary, the listening material points out that these systems are just indicate that the Anasazi were fully aware of that problem, they knew that to build those systems could help them store water.
Third, as in the reading material, it is said the tribe's population was overgrown and people had to leave as there was a limit of resources during the drought. However, the speaker says that as it is all scientists' hypothesis, the departure may be caused by a severe disease or the attack by another tribe instead of a major natural disaster.

In the listening material, the lecturer explains three points that disagree with what is listed in the reading material.
First, the writer says that the Anasazi may vanish as the result of global warming. It is said in the text that the time Anasazi abandoned was just the beginning of a long-time drought. The lecturer argues that because the drought did not happen on the place the Anasazi lived in(这句只有原因没结果) and points out certain evidence that proves trees were existed in the area at that time.
Second, the author takes irrigation systems as examples to support that the Anasazi suffered shortages of water. On the contrary, the listening material points out that these systems are just indicate that the Anasazi were fully aware of that problem, (and) they knew that(不要that了) to build those systems could help them store water.
Third, as in the reading material, it is said the tribe's population was overgrown and people had to leave as there was a limit of resources during the drought. However, the speaker says that as it is all scientists' hypothesis, the departure may be caused by a severe disease or the attack by another tribe instead of a major natural disaster.
