In the listening, the lecturer casts doubt on the reading’s argument that there are three advantages to make green roofs in cities and gives three main rebuttal claims.
First of all, the reading insists that green roofs can create space to bulid new parks. The professor, however, refutes that argument by saying that people will not be able to access the top of the buildings unless they work there. So green roofs mean nothing to many people.
The second point the author makes is that green roofs offer great views making peole feel happy. To rebut this claim, the speaker asserts that walking on the side walk, technically, it is impossible for people to see the view of green roofs which means that it is usless how great the view is.
Finally, the article contends that living roofs reduce cost by saving energy. In contrast, the speaker disputes it by stating that the additional cost of green roofs outweighs the cost saving. There are two main additional costs; one is installation cost and the other is maintenance cost. To lie specific, a motor company spent a lot of money on installing a green roof. Also it constantly needs to repair it by supplying soil and so on. Therefore, making green roofs is not saving money rather wasting money. |
