[face=Georgia]In the second place, the author fails to consider the changes (加that,否则从句没有引导词)may occur in different time and different place (places)and assumes everything is still in (under)all circumstances(有点别扭,改成everything is the same under all circumstances 吧,能好一点). According to the argument, the cost reduction happened after 14 years. It is incredible that everything remains the same during these years. In the common sense, various factors concerning the cost will greatly altered(很明显吧). However, the author neglects to compare the conditions in 1970 and with that (前面既然是复数,这里就该是those)in 1984. Thus, we cannot get the conclusion without any other clarification about the background information[/face].
以此段为例,T最近有点忙,不能全文修改了。。
