Questions 11-21 are based on the following passage and supplementary material. This passage is adapted from Iain King, "Can Economics BeEthical?" ©2013 by Prospect Publishing.
These human quirks mean we can never makepurely "rational" decisions. A new wave of behavioral economists, aided by neuroscientists, is trying to understand our psychology, both alone and ingroups, so they can anticipate our decisions in the marketplace more accurately. But psychology can also help us understand why we react in disgust ateconomic injustice, or accept a moral law asuniversal. Which means that the relatively new science of human behavior might also define ethicsfor us. Ethical economics would then emerge fromone of the least likely places: economists themselves.
18. The main idea of the final paragraph is that
A ) human quirks make it difficult to predict people ’ s ethical decisions accurately.
B ) people universally react with disgust when faced with economic injustice.
C ) understanding human psychology may help to define ethics in economics.
D ) economists themselves will be responsible for reforming the free market.
答案 : C
答案解析 : 本題問的是結尾段 ( lines 83-88 ) 的中心思想。根據中心題的解答技巧，我們要特別關註段落開頭和結尾。本段開頭提到 "These human quirks mean … " 顯然是對上文內容的承接和拓展，不可能是本段的中心。再看後文出現瞭轉折信號 "But psychology can also help us … "，緊接著後面又出現瞭 "Which means that … " 對其進行瞭解釋說明，根據結構即可判斷，"But" 後面的內容才是作者在本段想要表達的中心思想。在此，作者指出心理學能幫助我們理解為什麼人們對經濟不公正表現出厭惡或普遍接受道德法則 ( "react in disgust at economic injustice, or accept a moral law as universal" ) ，這意味著人類行為的新科學也有助於為我們明確道德標準 ( "define ethics for us" ) 。因此，答案為 C 選項。
A 選項錯誤，本段開頭雖然提到瞭 human quirks，但並不是本段的中心思想。
B 選項錯誤，這是細節內容，並不能涵蓋本段的中心思想。
D 選項錯誤，本段並沒有暗示經濟學傢將承擔自由市場重組的責任，犯瞭過度推測的錯誤。
