gre argument 145题目：
A new study collected data that shows that people who snore are more likely to gain weight than are people who do not snore. It is well known that many(1) people who snore also stop breathing frequently during the night for a few seconds, a condition called sleep apnea. The interruption of breathing wakes the person—often so briefly that the waking goes unnoticed—and can leave the person too tired(3) during the day to exercise(2,8). Anyone(4) who snores, therefore, should try to eat less(6) than the average person and to exercise more(5,7).
提纲：
(1)We do not know what fraction of people who snore actually suffer from sleep apnea.
(2)People who suffer from sleep apnea may actually exercise during the day although they are tired.
(3)The author fails to illustrate the actual effect of sleep apnea, thus the assumption that people who suffer from it will necessarily be tired is unwarranted.
(4)The assumption that all people who snore will necessarily eat more and exercise less than normal is unwarranted.
(5)The author’s assumption that people who snore should exercise more is contradictory to the assumption that those people are too tired to exercise.
(6)No evidence could illustrate that eating less could effectively result in reducing weight.
(7)The author ignores many other factors that would contribute to snore and gaining weight.
(8)The author fails to consider the possibility that obesity could reversely result in people snore.
