一、试题类型
逻辑推理实体的类型一般包括以下几种:
1. 有关结论的问题:
The term "pit bull" does not designate a breed of dog, as do the terms "German shepherd"and "poodle. " It is like the terms "Seeing-Eye dog" and "police dog," which designate dogs ac-cording to what they do.

答案(C)

2. 有关推论的问题

(D) Most of the applicants were highly qualified.
(E) The qualifications of applicants were not the only factor affecting admissions.
答案(E)

3. 有关架设的问题
Schools that train students in technical skills for a specific field of work are more successful,as measured by the percentage of students that gain employment in full-time6 jobs in the six-month period following graduation, than are institutions that teach a liberal arts curriculum.
Technical schools have a student employment rate of approximately 65 percent, whereas liberal arts schools have a rate of only 56 percent. This difference reveals that technical schools are more effectively meeting the challenge of providing education than are liberal arts schools.
Which one of the following is an assumption on which the above argument rests?
(A) Schools will not accurately7 report information if they believe that information will re-flect poorly on them.
(B) The curriculum of a school can be evaluated by examining the number and types of jobplacements achieved by its students.
(C) The percentage of students that gain employment following graduation is a measure-ment of that school s ability to provide education.
(D) The sole function of education is to help students gain employment.
(E) Technical schools and liberal arts schools serve different educational purposes.
答案(C)

4.有关加强(Strengthen)论证的问题。
Journalistic criticism of literature is falling victim to its own efforts to justify8 its existence.Critics believe that garner9 respect from their readers by ignoring objective description in favor ofapinionated commentary. Any new work is given the briefest of summaries, and then mercilessly:arved up in an effort to divine its deeper meaning. But the best journalist simply presents facts and allows his audience to decide their meanings independently. Critics should convey the truest
possible form of the works in question; let the art, and not the art critic, speak to us.
Which one of the following statements best lends support to the argument presented above?
(A) Liberals make all new work available to the interested public without regard to critical opinions.
(B) Because space is limited, it is not practical to reproduce completely every work that is criticized in print.
(C) Writers would likely alter their style if they knew that their works would simply be read
