The lecturer argues against the three measures mentioned in the

reading passage to a new species which call cane toad introduced to the Australian continent to reduce the population of that place.

The lecturer argues that the first measure, a national fence, would not avoid the flow of streams or rivers, so could allow young toads and toad eggs move to the other side of the fence. The reading passage, however, argues that such a fence would effectively cut off the route that animals used 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; The reading passage gives the opposite view: Organizing a large group of volunteers to join an extermination and speed to destruction of cane toads.

Finally, the lecturer objects to the third measure—using an infectious virus. The professor thinks that a virus intended to eliminate

Australia’s cane toad population may be will through animal

transportation to other continents .This is in direct contradiction with the claim in the reading passage that an infectious virus could be developed to stop the reproduct of cane toads without harming other species.

Both the author and the lecturer talk about selling and buying fossils by private collectors is an unfortunate development for both scientists and the general public, the reading and listening are contradictory to each other

First, the author says that the private collectors do not allow the public to view their collections. Because of this, people's interests of fossils will gradually decrease. However, the professor demonstrates a different idea that the public are more likely to see fossils , because some low level institutions, such as public schools, libraries could buy the fossils to display and that can Let these fossils have more public value.

Second, the author claims that scientists will miss out some major discoveries about the fossils. The lecturer challenges this view by claiming that the private collectors will take the fossils to the scientists to do scientific identification at first, and scientists could do examinations and tests on them. That is to say, scientists will still obtain the important discover. . According to the author, the third reason is that the collectors often

destroy valuable scientific evidence, because of their carelessness. this is contrary to the argument in the lecture that if the private collectors do not find them, there are also many fossils undiscovered. It is better to have fossils with some damages than to have them buried in the ground.

Generally, contrary to the belief in the reading passage that there are several ways can effectively pretend the spread of the cane toad in Australia, the professor asserts that none of these methods can get rid of it, besides, those may even cause the ecological damage in certain area. The lecture completely refutes the reading passage.

First of all, the writer presents an idea that the build of national fence may work. In contrast, the professor believes that the fence cannot effectively stop the toads from spreading. In order to prove this point, some details are provided by her that the young toads as well as the eggs of the toads are always inhabit nearby the stream, so the stream can carry them to the other sides. This contradicts what the reading passage indicates.

Besides, the listening material refutes the viewpoint showed in the passage that the toads can captured by the volunteers, and the eggs even easier to be captured and destroyed, by saying that the untrained volunteer are at high possibility to destroyed cause the decline of the native frogs, some of which are even endangered. She argues that the native frogs' eggs are hard to distinguish with the eggs of toads. This is another part where the lecture casts doubt on the reading.

Finally, the reading makes the point that the scientists have made the medicine so-called disease-causing virus to control the cane toad populations. On the contrary, the speaker holds a different point of view by saying that the toads toad terrible effect the ecological balance. Specifically, the lecturer states that the virus may cause the moving of the cane toad, which may carry the virus, to the other countries, in the end, destroy the ecosystem. The two ideas are just contradictory to each other.
