单选题 When it comes to jealousy, men and women aren't always on the same page. Previous studies have shown that, while men are more likely to see red over a partner's sexual infidelity, women are more upset by emotional cheating. Evolutionary psychologists- theorize that the difference is rooted in the sexes' historical roles--men wanted to guarantee that their partners were carrying their children, while women needed to feel secure that they and their children would be cared for by a committed partner. Yet, that evolutionary explanation doesn't account for a large group of men who say that emotional disloyalty is more upsetting than sexual infidelity, and women who are more upset by sexual betrayal.
To gain a more thorough understanding of gender and jealousy, researchers from Pennsylvania State University (PSU) approached the issue with some modem psychology. In a study published in the journal Psychological Science, researchers found that, while generally speaking, the evolutionary explanation of gender and jealousy held up, when viewed through the lens of attachment theory--broadly, the psychological theory about our tendency to foster intimate relationships with other people--both men and women with secure emotional histories were more likely to experience jealousy over emotional infidelity, and those who were insecure or dismissing, were more likely to be vexed by sexual cheating.
To tackle the issue, researchers recruited 416 college students from New York City, whose attachment styles were assessed through questionnaires containing a series of vignettes (short descriptions or pictures)--each reflecting either secure, fearful, preoccupied, or dismissing attachment styles. Participants were instructed to select the story that most accurately reflected their own attitude about romantic relationships, and were categorized accordingly. In a subsequent questionnaire, participants were asked whether they would be more upset by their partner "having passionate sexual intercourse with another person," or "forming a deep emotional attachment to another person."
They found that, regardless of gender, 77.3% of securely attached participants viewed emotional infidelity as more upsetting, while 64.8% of insecure or dismissing participants thought sexual cheating was worse. These findings, the authors say, shed light on the intricate psychological nature of jealousy, and may help to develop techniques to determine the underlying dynamics of sexual jeaiousy--a well-documented cause of spousal abuse, beating and even murder. The authors suggest that, gaining a better understanding of not only the broad differ ences in jealousy between the sexes, but of the differences in jealousy within genders, may help to identify methods for interrupting abuse by fostering stable, secure attachments.

单选题 The theory put forward by evolutionary psychologists

【正确答案】 C

【答案解析】事实细节题。根据关键词evolutionary psychologists定位到文章第1段。其中第3句提到进化心理学家提出理论说男女在嫉妒方面的不同源于他们性别的历史角色不同，但是紧接着以yet转折，指出这种理论不够全面，不够透彻，因此第2段第1句话就说“为了更加透彻地了解性别与嫉妒的关系，……”，由此可知C项正确。A项不是进化心理学家的理论，张冠李戴；B项shaped“形成，塑造”，选项表述颠倒了因果关系；D项“主要受到达尔文进化论的影响”文中并未提及，推理过度。

【正确答案】 D

【答案解析】事实细节题。根据专有名词缩写PSU定位文章第2段。通过题干可知本题主要考查PSU的研究结果，正确解答本题重在理解第2段的第2个句子。根据“长难句”的分析可以发现，进化心理学家对于性别与嫉妒的理论基本正确，但同时还必须考虑情感依附类型这一因素，据此可知，D项“除了性别，依附类型也会造成嫉妒方面的差异”正确。A项错在缺少generally speaking这一条件；B项“更多的试验参与者认为情感不忠更加令人愤怒”的论述过于笼统，小括号内的数据是对原文的故意曲解；C项is untrue文中并未提及，且研究者认为进化心理学家的理论基本正确，只是在这种前提之下，如果从情感依附类型的角度来考查这个问题，该理论还有待完善，所以不能得出结论说进化心理学家的理论是不对的。

单选题 What can be inferred from the last paragraph?

【正确答案】 C

【答案解析】推理判断题。根据题干定位最后一段。考查对段落中破折号处的理解。其中指出“性嫉妒已经被充分证明是导致配偶虐待、殴打甚至谋杀的原因”，故C项“记录表明性嫉妒是导致婚姻暴力的一个原因”正确；A项“嫉妒与性别无关，而是与情感依附类型有关”是对regardless of gender“暂且不论性别”的曲解，排除；B项前半句正确，但是后半句错误，因为文中说的是“可以帮助形成一些技巧来确定产生性嫉妒的潜在原因”；D项avoid推理过度，文中只说may help to identify methods，由此就推断can avoid过于武断，另外domesticviolence也过于宽泛。

单选题 Which of the following would be the best title for this text?

【正确答案】 B

【答案解析】主旨大意题。通过阅读全文，尤其是第1段的第1句话和第2段的开头第1句话，可以发现本文主要探讨男性和女性在嫉妒方面的不同表现，所以B项“性别与嫉妒”是最恰当的文章标题。A项“情感背叛VS性行为不忠”只是男女在嫉妒方面不同的表现，不能做文章标题；C项“情感依附类型与嫉妒”也不适合，因为情感依附类型确实是影响嫉妒行为的一种原因，但是它还是属于“性别与嫉妒”这个广义的范畴，D项“嫉妒的动力”与文章主旨不符。
