C.f (x1)< f(x2) D.不能确定 f(x1)与 f(x2)的大小
17.( 4 分)已知函数 f(x)=
,则下列说法中正确的是(

A.若 a≤0,则 f(x)≤ 1 恒成立 B.若 f( x)≥ 1 恒成立,则 a≥ 0 C.若 a<0,则关于 x 的方程 f(x)=a 有解 D.若关于 x 的方程 f(x)=a 有解,则 0< a≤ 1
第 6 页(共 19 页)
11.( 3 分)已知函数
的定义域是全体实数,那么实
数 a 的取值范围是 (﹣∞,﹣ ] ∪ [ 1,+∞) .
【解答】 解:若函数
则 a=1 时,显然成立, a=﹣1 时, f(x)= 若 a2﹣1≠0,
的定义域是全体实数, ,不成立,


解得: a≥1 或 a≤﹣ , 故答案为:(﹣∞,﹣ ] ∪ [ 1,+∞).
12.( 3 分)设函数 f(x), g( x)的定义域分别为 Df,Dg,且 Df? Dg.若对于任 意 x∈Df,都有 g(x)=f(x),则称函数 g( x)为 f(x)在 Dg 上的一个延拓函数. 设 f(x)=x2+2x,x∈(﹣∞, 0] ,g( x)为 f( x)在 R 上的一个延拓函数,且 g(x) 是偶函数,则 g(x)= x2﹣ 2| x| . 【解答】 解:由题意可得当 x≤0 时, g( x) =f(x)=x2+2x 由函数 g(x)为偶函数可得, g(﹣ x) =g(x) 当 x>0 时,则﹣ x<0,g(﹣ x)=x2﹣2x,则 g(x)=x2﹣2x ∴ g( x)=x2﹣2| x| 故答案为: x2﹣2| x|
( 3)是否存在自然数 a,使得函数 f (x)的值域恰为

古人用十二地支与十二生肖相对应,“子”位的鼠永远打头。

鼠与人类关系密切,有关鼠的童谣在旧时深受儿童喜爱,流行于京津一带的《小耗子偷油》,今天五十岁左右的人都会有印象;而《猫拿耗子》中“耗子大爷”的形象更带有几分老北京市民的懒散与穷讲究,十分可爱;不过,最让儿童神往的莫过于“老鼠娶亲”的民间传说,几乎流行于全国;春节前后,有关生肖的年画、剪纸,不仅是成年人点缀年节气氛的物品,更是儿童进入童话世界的向导。

在浙江绍兴一带,人们常称年画为花纸,鲁迅《狗·猫·鼠》一文忆及童趣有云:“别的一张‘老鼠成亲’却可爱,自新郎、新妇以至傧相、宾客、执事,没有一个不是尖腮细腿,像煞读书人的,但穿的都是红衫绿裤。

.【解答】解:由异面直线所成角的定义可知:过空间一点,分别作相应直线的平行线,两条相交直线所成的直角或锐角为异面直线所成的角故两条异面直线所成的角的取值范围是(0°,90°]故答案为:(0°,90°]3.(3分)给出以下命题“已知点A、B都在直线l上,若A、B都在平面α上,则直线l在平面α上”,试用符号语言表述这个命题已知A∈l,B∈l,若A∈α,B∈α,则l⊆α.【解答】解:用符号语言表述这个命题为:已知A∈l,B∈l,若A∈α,B∈α,则l⊆α.故答案为:已知A∈l,B∈l,若A∈α,B∈α,则l⊆α.4.(3分)设E、F、G、H分别是空间四边形ABCD的边AB、BC、CD、DA的中点,则四边形EFGH的形状一定是平行四边形.【解答】解:如图,连接BD.因为FG是△CBD的中位线,所以FG∥BD,FG=BD.又因为EH是△ABD的中位线,所以EH∥BD,EH=BD.根据公理4,FG∥EH,且FG=EH.所以四边形EFGH是平行四边形.故答案为平行四边形5.(3分)设点A∈平面α,点B∈平面β,α∩β=l,且点A∉直线l,点B∉直线l,则直线l与过A、B两点的直线的位置关系异面.【解答】解:假设l与AB不是异面直线,那么它们在同一个平面上,记这个平面为γ.∵A和l都在平面γ上,∴由它们决定的平面α在平面γ上,∴平面γ=平面α.同理γ=平面β.∴α=β,∵A∈α,∴A∈β,所以A在α与β的交线l上,与已知点A∉直线l,点B∉直线l相互矛盾.∴假设不成立,∴l与AB是异面直线.故答案为:异面.6.(3分)数列{a n}中,设S n是它的前n项和,若log2(S n+1)=n+1,则数列{a n}的通项公式a n=.【解答】解:由log2(S n+1)=n+1,得S n+1=2n+1,∴,当n=1时,a1=S1=3;当n≥2时,,当n=1时,上式不成立,∴.故答案为:.7.(3分)a,b是不等的两正数,若=2,则b的取值范围是(0,2).【解答】解:a,b是不等的两正数,且=2,须对a,b作如下讨论:①当a>b时,=0,则==a,所以,a=2,因此,b∈(0,2),②当a<b时,则=﹣b=2,而b>0,故不合题意,舍去.综合以上讨论得,b∈(0,2),故答案为:(0,2).8.(3分)计算81+891+8991+89991+…+81=10n+1﹣9n﹣10.【解答】解:原式=8×(10+102+…+10n)+(1+1+…+1)+(90+990+…+×10)=8×+n+(102﹣10)+(103﹣10)+…+(10n﹣10)=+n+﹣10(n﹣1)=10n+1﹣9n﹣10.故答案为:10n+1﹣9n﹣10.9.(3分)已知正方体ABCD﹣A1B1C1D1的棱长为1,则点C1到直线BD的距离为.【解答】解:如图所示,连接AC,BD,DC1,BC1.设AC∩BD=O,连接OC1.∵DC1=BC1,OB=OD.∴OC1⊥BD,∴OC1是点C1到直线BD的距离.OC1==.故答案为:.10.(3分)我们把b除a的余数r记为r=abmodb,例如4=9bmod5,如图所示,若输入a=209,b=77,则循环体“r←abmodb”被执行了4次.【解答】解:模拟程序的运行,可得a=209,b=77,r=55不满足条件r=0,执行循环体,a=77,b=55,r=22不满足条件r=0,执行循环体,a=55,b=22,r=11不满足条件r=0,执行循环体,a=22,b=11,r=0此时,满足条件r=0,退出循环,输出a的值为22.由此可得循环体“r←abmodb”被执行了4次.故答案为:4.11.(3分)设S n是数列{a n}的前n项和,a1=﹣1,a n+1=S n S n+1,则S n=﹣.【解答】解:∵a n=S n S n+1,∴S n+1﹣S n=S n S n+1,+1∴=﹣1,∴数列是等差数列,首项为﹣1,公差为﹣1.∴=﹣1﹣(n﹣1)=﹣n,解得S n=﹣.故答案为:.12.(3分)若三个数a,1,c成等差数列(其中a≠c),且a2,1,c2成等比数列,则的值为0.【解答】解:∵a,1,c成等差数列,∴a+c=2 ①又a2,1,c2成等比数列,∴a2c2=1 ②联立①②得:或或,∵a≠c,∴或,则a+c=2,.∴=.故答案为:0.13.(3分)在学习公理四“平行于同一条直线的两条直线平行”时,有同学进行类比,提出了下列命题:①平行于同一平面的两个不同平面互相平行;②平行于同一直线的两个不同平面互相平行;③垂直于同一直线的两个不同平面互相平行;④垂直于同一平面的两个不同平面互相平行;其中正确的有①③.【解答】解:①平行于同一平面的两个不同平面互相平行,正确;②平行于同一直线的两个不同平面互相平行或相交,不正确;③垂直于同一直线的两个不同平面互相平行,正确;④垂直于同一平面的两个不同平面互相平行或相交,不正确.故答案为①③.14.(3分)在n行n列矩阵中,若记位于第i行第j列的数为a ij(i,j=1,2,…,n),则当n=9时,表中所有满足2i<j的a ij的和为88.【解答】解:由题意可知:当i=1时,由2i<j,∴j取3,4,5,6,7,8,9当i=2时,j取5,6,7,8,9当i=3时,j取7,8,9当i=4时,j取9∴表中所有满足2i<j的a ij和为:a13+a14+a15+a16+a17+a18+a19+a25+a26+a27+a28+a29+a37+a38+a39+a49=3+4+5+6+7+8+9+6+7+8+9+1+9+1+2+3=88,故答案为:88二.选择题15.(3分)如图给出的是计算的值的一个程序框图,判断其中框内应填入的条件是()A.i>10 B.i<10 C.i>20 D.i<20【解答】解:框图首先给变量s,n,i赋值s=0,n=2,i=1.判断,条件不满足,执行s=0+,n=2+2=4,i=1+1=2;判断,条件不满足,执行s=+,n=4+2=6,i=2+1=3;判断,条件不满足,执行s=++,n=6+2=8,i=3+1=4;…由此看出,当执行s=时,执行n=20+2=22,i=10+1=11.此时判断框中的条件应满足,所以判断框中的条件应是i>10.故选:A.16.(3分)下列命题中,正确的共有()①因为直线是无限的,所以平面内的一条直线就可以延伸到平面外去;②两个平面有时只相交于一个公共点;③分别在两个相交平面内的两条直线如果相交,则交点只可能在两个平面的交线上;④一条直线与三角形的两边都相交,则这条直线必在三角形所在的平面内.A.0个 B.1个 C.2个 D.3个【解答】解:对于①,因为平面也是可以无限延伸的,故错误;对于②,两个平面只要有一个公共点,就有一条通过该点的公共直线,故错误;对于③,交点分别含于两条直线,也分别含于两个平面,必然在交线上,故正确;对于④,若一条直线过三角形的顶点,则这条直线不一定在三角形所在的平面内,故错误.故选:B.17.(3分)从k2+1(k∈N)开始,连续2k+1个自然数的和等于()A.(k+1)3B.(k+1)3+k3C.(k﹣1)3+k3D.(2k+1)(k+1)3【解答】解:从k2+1(k∈N)开始,连续2k+1个自然数的和=k2+1+k2+2+…+(k2+2k+1)=(2k+1)•k2+=2k3+3k2+3k+1=(k+1)2+k3.故选:B.18.(3分)已知方程组的解中,y=﹣1,则k的值为()A.3

7.如果2g甲烷含有x个甲烷分子,那么22gCO2中所含分子数是
A.4xB.3xC.xD.0.5x
【答案】A
【解析】
【详解】2g甲烷的物质的量为: = ,22g二氧化碳的物质的量为: =0.5mol,根据N=nNA可知,甲烷和二氧化碳的物质的量与含有的分子数成正比,则 mol:0.5mol=X:N(CO2),解得:N(CO2)=4X,故选A。
【详解】A、H3O+的质子数为11,电子数为11-1=10,OH-的质子数为9,电子数为9+1=10,电子数相同,故A错误;
A.a%
B.2a%
C.1−1.75a%
D.1−0.75a%
【答案】C
【解析】
【分析】NaHS、NaHSO3中“NaH”的总相对原子质量为24,与1个Mg原子的相对原子质量相等,所以可以从质量角度将“NaH”视为一个与Mg等效的整体A(即将“NaH”和Mg都换用“A”来表示,可看作其相对原子质量为24).那么,这样处理后混合物就相当于是由AS、ASO4、ASO3组成的了,而此时的混合物中A、S原子个数比为1:1,二者的质量比为24:32;利用硫元素的质量分数可求得A的质量分数,混合物中氧元素的质量分数=1-混合物中硫元素的质量分数-A元素的质量分数.

There are almost 2,000 of them, as compared with 180 in Japan, 164 in Argentina and 111 in Britain. The quality of some American papers is extremely high and their views are quoted all over the world. Distinguished dailies like the Washington Post or the New York Times exert a powerful influence all over the country. However the Post and the Times are not national newspapers in the sense that the Times is in Britain or Le Monde is in France, since each American city has its own daily newspaper. The best of these present detailed accounts of national and international news, but many tend to limit themselves to state or city news.Like the press in most other countries, American newspapers range from the “sensational”, which feature crime, sex and gossip, to the serious, which focus on factual news and the analysis of world events. But with few exceptions American newspapers try to entertain as well as give information, for they have to compete with the lure of television.Just as American newspapers cater to all tastes, so do they also try and appeal to readers of all political persuasions. A few newspapers support extremist groups on the far right and on the far left, but most daily newspapers attempt to attract middle-of-the-road Americans who are essentially moderate. Many of these papers print columns by well-known journalists of different political and social views, in order to present a balanced picture.As in other democratic countries American newspapers can be either responsible or irresponsible, but it is generally accepted that the American press serves its country well and that it has more than once courageously exposed political scandals or crimes, for instance, the Watergate Affair. The newspapers drew the attention of the public to the horrors of the Vietnam War.57.
