ARCH VERSION:

There is an argument of reading passage stating that some theories may be able to explain the reason of unknown sounds made around the Russian submarines underwater when patrolling between 1960 and 1989.However, the lecture totally disagrees with these three opinions.

To begin with, the noises were unlikely from the whales since the submarines were in very deep of water. Although the population of whales was rather huge around the submarine's area, the whales indeed were pretty far from the submarines. In addition, it is also impossible that submarines were not detecting such solid objects as large as whales.

In terms whether the zebra mussel will exert negative influence on North American, the passage and lecture are contradictory to each other. The author believes that zebra mussel might do harm the local species as they arrived while the lecturer holds a different opinion.

First of all, the author makes a point that the history events suggest the zebra mussel's invasion is unstoppable. In the past, human transportation makes it possible for zebra mussel spread around the whole Europe and it is likely to happen again in North American. However, the lecturer demonstrates a different idea that a change made in the "ballast water" will prevent the invasion of zebra mussel from continuing. He says that if we refill the "ballast water" with ocean water, the mussel will no longer survive because the saline water might probably kill them all.

The passage claims that wood companies in US would probably not receive ecocertification as companies in other countries do. While, in the lecture, the professor points out several points to substantiate that American wood companies would be most likely to advertising their products by pursuing ecocertification.

First of all, the professor claims that consumers in American pay less attention to advertising and, in fact, they value the advertising which independent from companies, like Consumer Agency. Certainly, consumers in America would like their products to become more environmentally-friendly. Therefore, wood companies in US would want to receive this ecocertification to gain reputation. That differs from what the passage states that consumers would not value the eco-healthy label as much as these labels 'new' or 'improved'.

The passage indicates that there are several measures to prevent the cane toad from spreading. The speaker, holds the view that these measures seems unsuccessful and will bring about the environmental damage.

To begin with, the passage supports the ideas that building native fence contributes to stopping cane toad to move further, for Australia used to manage to control the spread of another animal invader, rabbits. On the other hand, the speaker believes that it cannot stop them. Because the small toad and their eggs are normally living in the rivers and streams, which are able to carry them to another side, the fence is not of use.

The reading passage explores the topic of the “Let it burn” policy. The professor’s lecture deals with the same issue. However, she thinks that the “Let it burn” policy is fundamental positive policy, which contradicts what the reading states. And in the lecture, she uses three specific points to support her idea.

First, the professor argues in the lecture that the fire enhanced the diversity of vegetation in Yellowstone Park, even though the reading passage suggests that Yellowstone fires caused tremendous damage to the park's trees and other vegetation. This is because that the fire has created a opportunity for some new plants to grow, for instance, the small plants which needed open un-shaded area and the seeds which demanded high levels of heat to germinate, which means that the small vegetations would had a better environment after the large trees had been destroyed. Obviously, the professor's argument disproves its counterpart in the reading.

The passage mainly puts forward three theories to explain the purpose and meaning of the carved stone balls. Nevertheless, the professor in the lecture argues that none of the theories are convincing enough to identify what the carved stoneballs are made for.

Regarding on the first theory, carved stone balls being weapons used in hunting or fighting, the lecturer argues that if the stone balls were used as weapons for hunting or fighting like arrowheads and hand axes, both of which were common Neolithic weapons, they would show signs of wear or damage since they would be cracked or have pieces broken off in the fighting, but the surfaces of the balls are well preserved and show little signs of wear and damage. As a result, the stone ball cannot be used as weapons as the reading suggests.

The lecturer points out three different shortcomings of genetically modified trees. In the aspects of adaptation, economic lucrativeness, and environmental value, they never have overwhelming advantage over natural trees. That means the points made in the reading are partial and biased.

First, genetic modification doesn’t necessarily make a natural tree more resistant to environmental adversities. Although genetic reconstructing may make a species stronger in a specific condition as the reading indicates, the new strain lakes the genetic diversity of a natural species. Thanks to the marginal differences between individuals, there can always be some survivors among natural species following a large
