  (D) Peptide Hormones: How Scientists Are Attempting to Solve Problems of Their Detection

  (E) Peptide Hormones: The Role Played by Messenger RNA‘s in Their Detection

  选D

  不好读的一篇文章,抛开一切专业方面的障眼法,第一句话告诉我们,直到五年前,一种观点还是 astounding,惊人的,不容易让人相信的,后面所有的内容都是说实验室做了什么样的事来证明这个理论 idea ,也就是解决一个问题的结构。

  所以,“ 肽激素:科学家们如何尝试解决它们的定位问题 ”,D 的标题是合适的。

  (C) have been produced in some part of the body other than the brain

  (D) have escaped detection by molecular methods

  (E) play an important role in the functioning of the hypothalamus

  选C

  根据句 5 :

  13. Which of the following is mentioned in the passage as a drawback of the immunological method of detecting peptide hormones?

  (A) It cannot be used to detect the presence of growth regulators in the brain.
