weaken 的方法我觉得还有一种，是说原来的逻辑因果颠倒，比如OG 137生活规律和夫妻关系,还有大全SECTION IV 23题戴墨镜和忧郁的因果关系的那题。欢迎NN指正！
OG-137. A study of marital relationships in which one partner's sleeping and waking cycles differ
from those of the other partner reveals that such couples share fewer activities with each other
and have more violent arguments than do couples in a relationship in which both partners
follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles
can seriously jeopardize a marriage.
Which of the following, if true, most seriously weakens the argument above?
(A) Married couples in which both spouses follow the same sleeping and waking patterns
also occasionally have arguments than can jeopardize the couple's marriage.
(B) The sleeping and waking cycles of individuals tend to vary from season to season.
(C) The individuals who have sleeping and waking cycles that differ significantly from those
of their spouses tend to argue little with colleagues at work.
(D) People in unhappy marriages have been found to express hostility by adopting a
different sleeping and waking cycle from that of their spouses.
(E) According to a recent study, most people's sleeping and waking cycles can be
controlled and modified easily.
Questions 22-23
Doctors in Britain have long suspected that patients who wear tinted eyeglasses are abnormally prone to depression and hypochondria. Psychological tests given there to hospital patients admitted for physical complaints like heart pain and digestive distress confirmed such a relationship. Perhaps people whose relationship to the world is psychologically painful choose such glasses to reduce visual stimulation, which is perceived as irritating. At any rate, it can be concluded that when such glasses are worn, it is because the wearer has a tendency to be depressed or hypochondriacal.
23. Each of the following, if true, weakens the argument EXCEPT:
(A) Some people wear tinted glasses not because they choose to do so but because a medical condition of their eyes forces them to do so.
(B) Even a depressed or hypochondriacal person can have valid medical complaints, so a doctor should perform all the usual objective tests in diagnosing such persons.
(C) The confirmatory tests were not done for places such as western North America where the usual quality of light differs from that prevailing in Britain.
(D) Fashions with respect to wearing tinted glasses differ in different parts of the world.（B）
(E) At the hospitals where the tests were given, patients who were admitted for conditions less ambiguous than heart pain or digestive distress did not show the relationship between tinted glasses and depression or hypochondria. |
