1.According to the author, educating girls in developing countries may
A.be more rewarding than expected
B.cause annoying problems and difficulties
C.bring to an end social and economic problems
D.bring a family into a financially difficult situation
正确答案：A
解析：原文第一句即指出：’Educating girls quite possibly yields a higher rate of return than any other investment available in the developing world.’ 选项A中’more rewarding than expected’是对’higher rate of return’的合理同义转述；B、C、D在文中均无依据，属过度推断或曲解。
2.By saying “… the prophecy becomes self-fulfilling …” in Paragraph 2, the author means that girls will
A.be found less valuable than boys
B.find their goals in life unreachable
C.be discontented with their life at home
D.be capable of realizing their own dreams
正确答案：A
解析：原文语境：’Girls are thus seen as less valuable than boys and are kept at home… the prophecy becomes self-fulfilling, trapping women in a vicious circle.’ ‘Prophecy’指前文所述‘girls are less valuable’这一社会预设，而‘self-fulfilling’指因该预设导致实际行为（不让上学→缺乏能力→印证低价值），故A为直接对应；B/C/D均属主观引申，未被文本支持。
3.In the author’s opinion, a vicious circle can turn into a virtuous circle when _.
A.there are more daughters in a family
B.a family is rich enough to educate boys
C.a family has more but healthier children
D.mothers know the importance of educating girls
正确答案：D
解析：第二段明确指出：’An educated mother… insist on the development of all her children, ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation… will be educated and healthy. The vicious circle is thus transformed into a virtuous circle.’ 关键主语是’educated mother’，即母亲受教育→重视女儿教育→打破循环。D项准确概括此逻辑链；A/B/C均非原文因果核心。
4.What does the author say about women’s education?
A.It is the most important social issue.
B.It is now given top priority in developing countries.
C.It yields greater returns than other known investments.
D.It has aroused the interest of a growing number of economists.
正确答案：C
解析：首句即强调：’Educating girls quite possibly yields a higher rate of return than any other investment available in the developing world.’ 其中’any other investment’涵盖所有已知投资，C项’greater returns than other known investments’为忠实转述；A项’最重大社会议题’无依据（原文称’as much an economic as a social issue’）；B项’目前最高优先级’未提及；D项’越来越多经济学家关注’属合理推断但非作者明确陈述。
D.the unfair treatment of girls in developing countries
正确答案：A
解析：全文围绕教育女孩的经济回报展开：开篇点明’higher rate of return’，中间分析家庭决策的经济动因（incentives）、母亲教育对下一代人力资本的经济影响、工资增长数据等，结尾重申’economic advantages’。虽提及社会益处（’Few will dispute… social benefits’），但主旨明确聚焦经济维度；B/C/D均为局部信息，非主旨。
6.The World Health Organization has found that ________.
A.depression results in iron-deficiency anemia
B.depression gets more press attention worldwide
C.more people are disabled by depression than by anemia
D.iron-deficiency anemia is the greatest cause of disability
正确答案：C
解析：原文明确：’major depression is the single greatest cause of disability in the world—more than twice as many people are disabled by depression as by the second leading cause of disability, iron-deficiency anemia.’ 即抑郁致残人数 > 贫血致残人数，且抑郁是第一大原因；C项准确复述；A项因果倒置；B项与原文’Other diseases… may get more press coverage’矛盾；D项与’depression is the single greatest cause’直接冲突。
7.In the 4th century, depression was regarded as a ________.
A.physical disorder
B.psychological problem
C.psychological disease caused by physical disorders
D.physical disease induced by psychological disorders
正确答案：A
解析：原文：’As early as the fourth century, the symptoms of “melancholia” were well known. In other words, depression was first thought of as an exclusively physical illness—the loss of appetite, sleeplessness, irritability, and general depression was believed to have a physical, not a psychological cause.’ ‘exclusively physical illness’即纯生理疾病，对应A项’physical disorder’；B/D涉及心理因素，与’not a psychological cause’矛盾；C项混合病因，亦不符。
8.After the 19th century people began to realize that depression could result from ________.
A.anemia
B.iron deficiency
C.physical illness
D.psychological problems
正确答案：D
解析：原文：’It wasn’t until the nineteenth century—when the term depression was invented to substitute for melancholia—that a psychological understanding of the illness began to develop.’ 即19世纪起开始形成’psychological understanding’，意味着认识到心理因素可致病；D项’psychological problems’直接对应；A/B为贫血相关，属后文WHO数据中的对比项，非病因；C项’physical illness’是此前（4世纪）的观点，非19世纪新认识。
