NOT WEAKEN 是适用与假设题类.一般是起到对结论的加强作用的.出题的规律一般是 NOT+VERB,这种提的做法是把NOT去掉,如果起到对结论的质疑,就是答案了.

例1. In the 1960’s long-term studies of primate behavior often used as subjects tamaris, small monkeys

that were thought ideal because they require only small cages, breed frequently, and grow quickly.

Field studies were not used because they were costly and difficult. Tamarinds were kept caged in

male-female pairs, because otherwise, serious fights erupted between unrelated females. On the basis

of the fact that breeding occurred, tamarinds were viewed as monogamous.

  The view taken by the researchers concerning the monogamy of tamarinds deepened on a questionable

assumption. Which of the following could have served as that assumption?

(A) The suppression of fighting between related females serves to protect their common genetic

inheritance.

(B) Adult male tamarinds contribute to the care of tamarind infants.

(C) The social system of tamarinds requires monogamous pairing.

(D) Male tamarind monkeys do not display aggressive behavior in the wild.

(E) The way the tamarinds were kept in cages did not affect their mating behavior.

不过个人认为,作逻辑题最好不要把它们分得太细,找出关键元素是最好的方法

另外给大家几个not + weaken的例题， 希望能帮助大家巩固一下

1. A private bus company gained greater profits and provided bus service to the area at lower fares by   running buses more frequently and stimulating greater rider-trip. Hoping to continue these financial trends, the company plans to replace all older buses with niew, larger buses, including some duble-decker buses.

 The plan of the bus company as described above assumes all of the following EXCEPT

 (A) the demand for bus service in the company's area of service will increase in the future

 (B) increased efficiency and revenues will compensate for any new expenses the company incurs

 (C) the new buses will be sufficiently reliable to ensure the company a net financial gain once they are in  place

 (D) driving the new buses will be no more difficult than driving the buses they are to replace

 (E) the larger, double-decker buses will not face obstacles such as height and weight restrictions in the bus company's area of service

Answer: D

2. Blood banks will shortly start to screen all donors for NANB hepatitis. Although the new screening tests are extimated to disqualify up to 5 percent of all prospective blood donors, they will still miss two-thirds of donors carrying NANB hepatitis. Therefore, about 10 percent of actual donors will still supply NANB-contaminated blood

  The argument above depends on which of the following assumptions?

(A) Donors carrying NANB hepatitis do not, in a large percentage of cases, carry other infections for which reliable screening tests are routinely performed

(B) Donors carrying NANB hepatitis do not, in a large perccentage of cases, develop the disease themselves at any point

(C)  The estimate of the number of donors who would be disqualified by tests for NANB hepatitis is an underestimate.

(D) The incidence of NANB hepatitis is lower among the potential blood donors than it is in the population at large

(E) The donors who will still supply NANB-contaminated blood will donate blood at the average frequency for all donors.

Answer:A
