下面有些是自查的错误,先谢谢了^_^
I fundamentally agree with the conclusion that the government should preserve publicly owned wideness areas, however, whether the areas needed to be maintained in aboriginality should depend on the specific situation of the area. Howbeit I do not approve the latter assertion that only a few people would arrive there because it is not accords with the changing rapidly world and the phenomenon that urban expansion, even though some areas are indeed remote.
There are three fundamental arguments for imposing the government to protect the diminishing wildness areas. The first has to do with the culpability and the responsibility. To the extent that the excessive anthropogenic events have seriously affected the dedicate balance of the natural environment and intricate matrix of the interdependent relationships between wild species, we humans have the duty to take affirmative actions, especiallty through the government that the most powerful organization, to protect the few existed wildness areas. The second one is appeal to the self-preservation. Since the global environment is in dedicate balance as discussed above, the diminishing and disappear of wildness areas can set into motion a serises(series) of species exstinctions(extinctions) and the balance destruction of other areas, and ultimately endanger the survivel(survival) of our human beings. The third argument comes to the rich and abundant resources in the wildness areas, which has a significant meaning for researchers of biology and ecology Researchers are likely to continue to seek the answer of the origination and evolution of life, which has inestimable significance not only on the biological technology but also the ultimate question of life.
Moreover the government should take the reasonable and appropriate action to certain wildness place. For example, it is ture(true) that we should keep the natural state of evergland(everglade), forest and tropical rainforest. However, when it comes to other areas such as Sahara where should be improved rather than remained in natural state. The expansion of Sahara largely caused by human activities and if we leave aside the problems or just keep it on the harsh desert will threathen(threaten) our survival.
However the speaker's latter assertion that wildness areas are so remote that merely people would arrive which contrast with the facts that rapidly expanding areas and scope of human activities. Humankind have never stop the step of exploring new habitat, especially at today's time that population rapidly growing, resources being depleted and techology(technology) developing at a speed that no one can image. There are several plans regards to explore and even move to mars, let alone the wildness areas on the touchable earth. As a result it is actually a harsh and difficult task for the government to protect the natural areas, and on the other hand, we can also infer from the urgent and harsh global situation that remain of wildness area might also have some unknowable values on a economic self-interest level.
In sum, I agree that the government should take action to prectect(protect) the wildness areas based on specific circumstances and analyze case-by-case in the respects that responsibility of environmental protection, human beings' self-preservation and sciencific(scientific) value of the natural resources. In addition, as the expanding of human activities area, there might be unknown value about the significant already measure.

The following appeared in a memo from the president of Viva-Tech, a manufacturer of high-tech medical equipment.
“In order to reduce costs, we should close some of our existing small assembly plants and build a large central plant. Grandview would be an ideal location for this new plant. First, of the locations that we have considered, Grandview has the largest adult population, so that we will be able to staff our plant quickly and easily. Second, since the average wage earned by workers in Grandview is less than that in the other locations, we should be able to keep production costs low. Last, as an inducement for us to build there, Grandview’s town council has offered to allow us to operate for the first three years without paying city taxes.”
The argument recommends that Viva-Tech should build a large central plant, at Grandview, in ordor(order) to reduce costs. To sustain the conclusion, the arguer try to illustrate that it is easily to staff the plant and the prodution(production) costs will low in G, what's more the local council has promise the new plant need not to pay the city taxes in three years. At first blush, the arguer appears somewhat convincing, however, from further logic perspective I can find it suffers from several logical flaws.
To begin with, the auther(arguer) provide no evidence to illustrate that changing the small assembly plants into a unite one can reduce the cost, because at sometimes the small plant can be more flexible to the market, and the cost of the place and workers might more cheaper than a large one. Moreover, to finish the restruction(restructuring) it is also need a lot of invest and whether the reduced cost is larger than the invest is worthy to consider.
Granting such a measure can really reduce the cost, however the arguer wrongheaded assume that because G has the largest adult population, it will be quick and easy to staff their plant. The arguer ignore the possibility that the adults in G have got little education, or they are mostly old people. If it is true, the number of the adult will help little for the new plants. Or perhaps, most of the adults work out of G and only live here because the low cost for living in G. At any event, the fact lends little support for the conclusion.
Next, The arguer also has the naive idea that the production costs only desided(decided) by the average wage of the workers. There are many other factors such as transportation and the supply of material. Perhaps, the G is a remote town and there is no mature means of transportation, so it will be hard for the new plant to transport in material and out their productions. Or perhaps, there is no industrial base in town, and it will hard for the plant to buy materials and get a further development.
And then, although the G's town council has promised cut the city tax in three years. However, it is highly possible that the local city taxes is only a little part compared with the national taxes or the taxes pay for the environmental protection. If it is so, the measure will help a lot. Even the measure really has it function to the new plants, however, the arguer gives no information about other towns to compare with. There might some other places are better than G. And then, no evidence can proof that the new plant can profit in three years , so it must be considered whether the invest is worth the money saved.
In sum, the arguer fails to sustain his conclusion. To make the argument more convincing and sound, the arguer has no choice but provide more evidences to proof that building such a large central plant indeed can help to cut the costs and more information(不可数) about G and other places to illustrate G is the best location for the plant.
