我知道在gmat中归纳考的很少，但是我觉得是练习阅读的好机会。特别是有些归纳的题目，题干比较长不知道从哪里下手。 （1）4. If the regulation of computer networks is to be modeled on past legislation, then its model must be either legislation regulating a telephone system or else legislation regulating a public broadcasting service. If the telephone model is used, computer networks will be held responsible only for ensuring that messages get transmitted. If the public broadcast model is used, computer networks will additionally be responsible for the content of those messages. Yet a computer network serves both these sorts of functions: it can serve as a private message service or as a publicly accessible information service. Thus neither of these models can be appropriate for computer networks.
The passage is structured to lead to which one of the following conclusions?
(A) Regulation of computer networks is required in order to ensure the privacy of the messages transmitted through such networks.
(B) The regulation of computer networks should not be modeled on any single piece of past legislation.
(C) Computer networks were developed by being modeled on both telephone systems and television networks.
(D) Legislators who do not have extensive experience with computers should not attempt to write legislation regulating computer networks.
(E) A computer network merely duplicates the functions of a telephone systems and a television system.
（2）12. In the Centerville Botanical Gardens, all tulip trees are older than any maples. A majority, but not all, of the garden's sycamores are older than any of its maples. All the garden's maples are older than any of its dogwoods.

(C) Some sycamores are not as old as the oldest dogwoods.
(D) Some tulip trees are not as old as the oldest sycamores.
(E) Some sycamores are not as old as the youngest tulip trees. d/e之间我没有分开
24. The body of anyone infected by virus X will, after a week, produce antibodies to fight the virus: the antibodies will increase in number for the next year or so. There is now a test that reliably indicates now many antibodies are present in a person’s body. If positive, this test can be used during the first year of infection to estimate to within a month how long that person has had the virus.
Which one of the following conclusions is best supported by the statements above?
(A) Antibodies increase in number only until they have defeated the virus.
(B) Without the test for antibodies, there is no way of establishing whether a person has virus X.
(C) Antibodies are produced only for viral infections that cannot be fought by any other body defenses.
(D) If a person remains infected by virus X indefinitely, there is no limit to the number of antibodies that can be present in the person’s body.
(E) Anyone infected by virus X will not a time fail to exhibit infection if tested by the antibody test
