新gre考试实施以来,参加了新版gre考试的考生都觉得阅读部分的题难度增加了,这主要是由于新gre考试逻辑阅读需要考生的逻辑反应一定要比以前更快,可能考生还是有点不习惯,或是没有准备充足。那么,接下来的几天,小编将给大家搜索整理一些新gre考试逻辑阅读的练习题,希望考生能从平日的练习中总结规律,找到解题技巧。
Until about five years ago, the very idea that peptide
hormones might be made anywhere in the brain besides
the hypothalamus was astounding. But laboratory after
laboratory found that antiserums to peptide hormones,
5 when injected into the brain, bind in places other than the
hypothalamus, indicating that either the hormones or
substances that cross-react with the antiserums are present.
The immunological method of detecting peptide
hormones by means of antiserums, however, is
10 imprecise. Cross-reactions are possible and this method
cannot determine whether the substances detected by the
antiserums really are the hormones, or merely close relatives.
Furthermore, this method cannot be used to
determine the location in the body where the detected
15 substances are actually produced. New techniques of molecular
biology, however, provide a way to answer these questions.获得更多gre考试咨询点击进入免费咨询顾问或联系QQ客服:800004500
It is possible to make specific complementary
DNAs that can serve as molecular
probes to seek out the messenger RNAs
20 of the peptide hormones. The brain cells
containing these mRNAs can then be isolated and their
mRNAs decoded to determine just what their protein
products are and how closely the products resemble
the true peptide hormones.
11. Which of the following titles best summarizes the passage?
Is Molecular Biology the Key to Understanding Intercellular Communication in the Brain?
Molecular Biology: Can Researchers Exploit Its Techniques to Synthesize Peptide Hormones?
The Advantages and Disadvantages of the Immunological Approach to Detecting Peptide Hormones
Peptide Hormones: How Scientists Are Attempting to Solve Problems of Their Detection
Peptide Hormones: The Role Played by Messenger RNAs in Their Detection
12. The passage suggests that a substance detected in the brain by use of antiserums to peptide hormones may
have been stored in the brain for a long period of time
play no role in the functioning of the brain
have been produced in some part of the body other than the brain
have escaped detection by molecular methods
play an important role in the functioning of the hypothalamus
13. Which of the following is mentioned in the passage as a drawback of the immunological method of detecting peptide hormones?
It cannot be used to detect the presence of growth regulators in the brain.
It cannot distinguish between the peptide hormones and substances that are very similar to them.
It uses antiserums that are unable to cross the blood-brain barrier.
It involves a purification process that requires extensive training in endocrinology.
It involves injecting foreign substances directly into the bloodstream.
答案:D/C/B
以上即是阅读练习题,对于新gre考试逻辑阅读,考生除了采取题海战术,其实更应该做的就是总结。如果能从平日的练习中找到解新gre考试逻辑阅读题的思路,那么,要比采取题海战术更好。
