Read the statement and the instructions that follow it,and then make any notes that will help you plan your response.Begin typing your response in the box at the bottom of the screen.          

The following appeared as part of an article in a magazine devoted to regional life.
 
"Corporations should look to the city of Helios when seeking new business opportunities or a new location. Even in the recent recession,Helios's unemployment rate was lower than the regional average. It is the industrial center of the region, and historically it has prodded more than its share of the region's manufacturing jobs. In addition, Helios is attempting to expand its economic base by attracting companies that focus on research and development of innovative technologies."
 
Discuss how well reasoned. ,. etc.

这题反而不太会写，本来想一条一条驳斥，就是失业率， 过去不能代表未来啥的。 可是后来发现其实一条一条写过来说的也就是一个点， 所给证据无法结论。所以写成现在这样了。关键貌似找不到递进， 3个点都是平行的。The author believe that corporations should consider Helios when looking for new business opportunities or a new location because the unemployment rate was low, the city is the industrial center with good past job records and the city is planing to attract more companies. Here, however, the author omits many important aspects that needed to be addressed to substantiate the argument, leaving the argument unconvincing and vulnerable. First off, the author did not address why these points- low unemployment rate, industrial center, and future plans- can benefit corporations, because lower unemployment can mean less readily available labors in the market, past experience place no guarantee in the future, and attracting more companies can make increase the competitiveness in the market. The author fails make convincing argument that these points can benefit a company, making the argument ill-founded. Second, event the points listed in the argument can somehow benefit corporations, the author still did not address why Helios is better off than all other cities. Because the author never address other cities and did not addresses why these points can be decisive advantages for Helios. Different companies are looking for different merits in different cities, for example, some companies are looking for nature resources as the decisive point to open their new branches, others may looking for location and transport facilities as the decisive points. The author made a over generalized statement. last, the author did not address why the points listed can be new business opportunities. Because the author never address the market in the Helios, nor does he address the potential customers in than city, throughout the passage there is nothing that can used to buttress the idea that there are business opportunities in city Helios.

Environmental organizations want to preserve the land surrounding the Wilgrinn Wilderness Area from residential development.  They plan to do this by purchasing that land from the farmers who own it.  That plan is ill-conceived:  if the farmers did sell their land, they would sell it to the highest bidder, and developers would outbid any other bidders.  On the other hand, these farmers will never actually sell any of the land, provided that farming it remains viable.  But farming will not remain viable if the farms are left unmodernized, and most of the farmers lack the financial resources modernization requires.  And that is exactly why a more sensible preservation strategy would be to assist the farmers to modernize their farms to the extent needed to maintain viability.
