某钢筋混凝土框架柱基础，柱截面500mm×500mm。基础埋深2.0m，经修正后的地基持力层承载力特征值fa=230kPa。基础埋深范围内土的加权平均重度γm= 18.0kN/m3。基础混凝土为C25，混凝土抗拉强度设计值ft=1.27N/mm2；钢筋采用HPB235，fv=210N/mm2。基础下做100厚C10混凝土垫层，基础台阶拟采用阶梯形，每阶高度300，基础总高度900mm。上部结构荷载效应的标准组合：Fy=2780kN。 若已计算出基础底板承受的弯矩Mk=1000kN·m，根据规范强制性条文，按抗弯计算出基础底板受力筋面积最接近的值为（）。
如图所示某柱下独立基础，基础底面尺寸3.0m×2.5m，上部结构传至基础的荷载效应：轴向荷载Fk=1650kN，基础埋深1.5m(不考虑相邻基础荷载的影响)。 假设Po>fk，计算基础底面下6m内主要压缩土层的最终沉降量时，沉降计算经验系数ψc的取值最接近（）。
Speech, whether oral or written, is a used commodity. If we are to be heard, we must (1) our words from those (2) to us within families, peer groups, societal institutions, and political networks. Our utterances position us both in an immediate social dialogue (3) our addressee and, simultaneously, in a larger ideological one (4) by history and society. We speak as an individual and also, as a student or teacher, a husband or wife, a person of a particular discipline, social class, religion, race, or other socially constructed (5) . Thus, to varying degrees, all speaking is a (6) of others’ words and all writing is rewriting. As language (7) , we experience individual agency by infusing our own intentions (8) other people’s words, and this can be very hard.(9) , schools, like into churches and courtrooms, are places (10) people speak words that are more important than they are. The words of a particular discipline, like those of "God the father" or of "the law," are being articulated by spokespeople for the given authority. The (11) of the addressed, the listener, is to acknowledge the words and their (12) . In Bakhtin’s (13) , "the authoritative word is located in a distanced zone, organically connected with a (14) that is felt to be hierarchally higher."(15) , part of growing up in an ideological sense is becoming more "selective" about the words we appropriate and, (16) , pass on to others. In Bakhtin’s (17) , responsible people do not treat (18) as givens, they treat them as utterances, spoken by particular people located in specific ways in the social landscape. Becoming alive to the socio-ideological complexity of language use is (19) to becoming a more responsive language user and, potentially, a more playful one too, able to use a (20) of social voices, of perspectives, in articulating one’s own ideas.
