分论点2 Mind map：
句式：(主体段)
First of all, the author states that ___________. In contrast, the speaker confutes that _____________. So, the lectures totally disagree with the view made in the reading.
示例：
First of all, the author states that plants could better protect themselves against freezing damage since the folded leaves expose less of surface to the air and keep more heat at freezing night. In contrast, the speaker confutes that plants don’t have a source of internal heat, and thus they will suffer the same damage from the freezing outside environment no matter they fold leaves or not. So, the lectures totally disagree with the view made in the reading.
重庆新航道April老师提示：实际写作的时候，要注意结合因果关系去点明文章中的重点逻辑，尽量一句话成功概括中心内容。而听力内容也可以利用因果+举例的连词去串联，会显得思路更为清晰。
