患者女，30岁。右下后牙进食嵌塞痛2周，偶有喝冷水疼痛。无自发痛。检查发现右下第一磨牙面深龋洞，冷测反应正常，冷刺激入洞出现一过性敏感，叩痛（-），去净腐质后洞底无穿髓孔，该患牙应做的治疗是（）

A.双层垫底后充填

B.安抚治疗以消除症状

C.活髓切断

D.直接盖髓

E.根管治疗

答案

参考答案：A

解析：进食嵌塞痛，检查发现深龋洞，冷测反应正常，冷刺激入洞出现一过性敏感，叩痛（-），去净腐质后洞底无穿髓孔，所以诊断为深龋。因为深龋近髓，需用双层垫底后充填，所以A正确。安抚治疗以消除症状不能消除根本，所以B错误。活髓切断用于牙髓炎，所以C错误。直接盖髓用于露髓，所以D错误。根管治疗也不用于深龋治疗，所以E错误。故此题选A。

Passage twoEducating girls quite possibly yields a higher rate of return than any other investment available in the developing world .women’s education may be unusual territory for economists ,but enhancing women’s contribution to development is actually as much an economic as a social issue .and economics ,with its emphasis on incentives ,provides guideposts that point to an explanation for why so many girls are deprived of an education Parents in low-income countries fail to invest in their daughters because they do not expert them to make an economic contribution to he family :girls grow up only to marry into somebody else’s family and bear children .Girls are thus seen as less valuable than boys and kept at home to do housework while their brothers are sent to school-the prophecy becomes self-fulfilling ,trapping women in a vicious circle of neglect. An educated mother ,on the other hand ,has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can 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 of girls ,as well as of boys ,will be education and healthy . The vicious circle is thus transformed into a virtuous circle. Few will dispute that education women has great social benefits.But it has enormous economic advantages as well .Most obviously ,there is the direct effect of education on the wages of female workers.Wages rise by 10 to 20 percent for each additional year of schooling. Such big returns are impressive by the standard of other available investments ,but they are just the beginning .Education women also has a significant impact on health practices,including family planning.
