9.ADf(x)的定义域为(-o,0)U(0,+o).因为f(-x)=ln|-x|=ln|x|=f(x),所以f(x)为偶函数,A正确.当x>0时,f(x)=lnx,f(x)在(0,十o∞)上单调递增,所以f(x)在(一∞,0)上单调递减,则f(一4)=f(4)>f(3),B错误,D正确.令f(x)=0,得x=士1,则f(x)有2个零点,C错误.10.BC因为(0.005+0.010+0.025)×10=0.40.5,所以这80块豆田的亩产量的中位数不低于180kg,则A错误.因为210一150=60,200一160=40,所以这80块豆田的亩产量的极差高于40kg,且不高于60kg,则B正确.在这80块豆田中,亩产量不低于190kg的豆田所占比例为(0.015+0.005)×10×100%=20%,则C正确.因为(0.005+0.010+0.025)×10=0.40.75,所以这80块豆田的亩产量的第75百分位数高于或等于180kg,则D错误

11.(1)电池组(2分)低压交流电源(2分)(2)C(2分)【解析】本题考查探究小车速度随时间变化的规律实验,目的是考查学生的实验探究能力。(1)电磁打点计时器使用交流电源,所以不需要的器材是电池组。电磁打点计时器还需要低压交流电源。(2)长木板不能侧向倾斜,但是可以一端高一端低,选项A错误;在释放小车前,小车应尽量靠近打点计时器,以便能在纸带上打出更多的点,有利于处理实验数据和减小误差,选项B错误;实验中应先启动打点计时器,然后释放小车,选项C正确;打点计时器应接在低压交流电源上,选项D错误。

3.A【解析】本题考查唐朝三省六部制,考查学生获取和解读历史信息、分析历史问题的能力和历史解释的素养。结合所学知识可知,唐朝中书省承旨皇帝并拟定诏书,门下省负责审核封驳,政事堂这一变动使“国政枢密皆委中书”,表明中书省地位上升,门下省地位下降,这是皇权扩张的结果,故选A项;政事堂从门下省移至中书省,三省长官集体办公形式并未发生变化,故排除B项;这一变化只是表明中书省地位上升,门下省地位下降,三省机制仍然存在,故排除C项;三省的运作机制制约皇帝随意决策,而这种运作机制未发生变革,故排除D项。
4.A【解析】本题考查宋代商品经济,考查学生获取和解读历史信息、分析历史问题的能力和历史解释的素养。根据材料信息可知,北宋熙宁年间,相当多的城镇的商税收入都超过本州一个县或几个县的收入,这与当时商品经济发展有密切关系,故选A项;宋代并未废除重农抑商政策,故排除B项;材料无法说明市镇的规模,故排除C项;材料只分析了商税的情况,无法说明政府整个财政收入的概况,故排除D项。
