　　TPO 15

　　The lecturer argues against the three measures mentioned in the reading passage to reduce the population of the cane toad, a species introduced to the Australian continent.

　　The lecturer argues that the first measure, a national fence, would not prevent the flow of streams or rivers and, therefore, would allow young toads or toad eggs to travel to the other side of the fence. The reading passage, however, argues that such a fence would effectively cut off the Route that animals use to establish colonies and expand in population.

　　Regarding the second measure, recruiting a large group of volunteers, the lecturer explains that volunteers often have difficulty distinguishing between cane toads and native frogs, an endangered species.来源：北京新航道托福培训 Therefore, volunteers might kill members of both species. The Reading passage gives the opposite view. Organizing a large group of volunteers to join an extermination campaign would speed the destruction of cane toads.

　　Finally the lecturer objects to the third measure—using an infectious virus. She points out that a virus intended to eliminate Australia’s cane toad population could be transmitted through animal transportation to other continents where cane toads are an essential part of the ecosystem. This is indirect contradiction with the claim in the reading passage that an infectious virus could be developed to stop the reproduction of cane toads without harming other species.
