绵阳2016级一诊给分细则
绵阳市高中2016级第一次诊断性考试文科综合(地理)参考答案及评分标准(内部交流请勿外传)(整理绵阳南山中学实验学校周德伟)一、选择题(44分)1——5:BDCCB 6——11:DDABCC二、非选择题(56分)36题(24分)(1)深居内陆/距海洋较远1′(水汽难以到达),年降水量少1′;上游集水区海拔高1′,冬半年降雪为主,积雪常年或季节性累积/积雪、冰川覆盖面积/总量大2′,春、夏季融化。
题干“说明……原因”,答题语言要有“前因后果”,分值为5分,平均分是3.66/3.28分。
学生答题主要问题是答案要点过多,重复啰嗦,或者要点过少仅集中在冰川冰雪融水补给角度作答,究其原因主要是答案建模混乱,语言因果关系不当,甚至没有,还有就是对冰川融水和季节性积雪(冰雪)融水区分不清楚。
题干中提到了补给,可建模补给类型(雨水、冰川、积雪、地下水和湖泊水),然后结合材料(冰川51.5%,冰雪26.1%,雨水22.4%)→答案结构(建模)应该是“雨水补给少,冰川、积雪融水补给多”两个方面。
分值为5分,给分组合(2分3分或2个2分1个1分),即2点或3点答案。
(2)水位年际变化小(2分);有明显的季节变化,春、夏汛期水位高/春夏水位高,秋冬水位低(2分);夏季水位日变化明显(要带有夏季的时间限制)(1分)。
题干“简述……特征”是描述其时间变化特征,分值为5分,平均分是2.09/1.79分。
学生答题主要问题是第一,仅围绕“季节变化”展开,先总述“季节变化大”,然后分述“夏季…冬季…”;“日变化”有学生答到,但缺少时间(夏季)的限定,得分率低;“年际变化”答到的更少,部分学生混淆了“年际”和“年季”;第二答出“季节变化”后,为弥补要点的不足,就用大量的语言去阐释原因来凑点。
针对某个事物特征的某一角度的小角度描述,应从更小角度去展开(符合现在高考所倡导的小切口大纵深),该题“时间变化特征”唯一展开角度就是时间的尺度,可按日月年进行展开,即日变化→月变化(季节变化)→年际变化。

﹣1),故g(﹣3)=﹣27++18=,g(﹣2)=﹣8+6+12=10,g(0)=0,作g(x)=x3+x2﹣6x的图象如下,,结合图象可知,实数m的取值范围为[,10).21.己知函数f(x)=lnx﹣ax+l,其中a∈R.(1)求f(x)的单调区间;(2)当a=1时,斜率为k的直线l与函数f(x)的图象交于两点A(x1,y1),B(x2,y2),其中x1<x2,证明:;(3)是否存在k∈Z,使得f(x)+ax﹣2>k(1一)对任意x>l恒成立?若存在,请求出k的最大值;若不存在,请说明理由.【考点】利用导数研究函数的单调性;利用导数求闭区间上函数的最值.【分析】(1)求出原函数的导函数,然后对a分类求得函数的单调区间;(2)把a=1代入函数解析式,然后利用分析法把证明,转化为证<<.分别令,k
