62. The following appeared in the letters-to-the-editor section of a local newspaper.
Muscle Monthly, a fitness magazine that regularly features pictures of bodybuilders using state-of-the-art exercise machines, frequently sells out, according to the owner of Skyview Newsstand. To help maximize fitness levels in our towns residents, we should, therefore, equip our new community fitness center with such machines.
当地报纸上给编者的信板块：
一份叫Muscle Monthly的健康杂志规律性地刊登用最好的练习器械的健美运动员的照片。据skyview报摊的摊主说它常常卖完。为了提升我镇居民的健康水平，大家应该给大家的新健身中心装备如此的器械。
1. The bodybuilders may just pretend to be using the state-of-the-art exercise machines while, in fact, their excellent body conditions are due to the use of other types of equipment. And, they just do so for the adverti百度竞价推广ent purpose.
2. The circulation is just one of the indicators1 of the popularity of the magazine. What is more, I can find no direct relationship between the popularity of the magazine and the author's suggestion that we should equip the community with the state-of-the-art excercise machine.
3. The machines for body building will not necessarily have the same effect on fitness.
1， 假如杂志卖光得快可能不是由于这个器材好，非常可能是价钱实惠，和其他的内容。
2， 那些人非常可能并不真的用这类机器，而只不过摆出造型。
3， 若是为了body-building的机器非常可能否fitness。譬如，cardiovascular fitness。
In this argument the author concludes that the new community fitness center should be equipped with the state-of-the-art exercise machines featured in Muscle Monthly magazine. In support of this recommendation two reasons are offered: Muscle Monthly contains pictures of bodybuilders using such machines, and Muscle Monthly is a popular magazine, as evidenced by the fact that it frequently sells out at the local newsstand. This argument is questionable2 on two counts.
First, a major implication of the argument is that the bodybuilders pictured using the machines in Muscle Monthly magazine reached their state of fitness as a result of using these machines. The only evidence offered to support this contention3, however, is the pictures in the magazine. It is possible that the bodybuilders pictured use different equipment for their workouts and are merely posing with the machines for advertising4 purposes.
Second, the author assumes that machines that are suitable for bodybuilding will also be suitable to help maximize the fitness levels of the towns residents. This assumption is highly questionable. Machines designed to increase muscle development are significantly different from those designed to increase cardiovascular fitness. Consequently, it is unlikely that the machines pictured in the magazine will be of much use to help maximize the fitness levels of the towns residents.
In conclusion, this argument is unconvincing. To strengthen the argument the author would have to show that the bodybuilders pictured using the exercise machines actually used the machines to reach their level of muscle development. Additionally, the author would have to show that the machines were suitable for increasing the fitness levels of the persons using them.
