When the policemen came, Harry and his father went to talk to them. "I saw the robber," Harry told the policemen. "I can describe him. He was about fifty years old. He was bald with a big, red nose and thick lips. And he had big ears. He was quite tall and thin. He had something wrong with his right leg." "How do you know that?" one of the policemen asked Harry. "He limped," Harry said. "What was he wearing?" the other policeman asked. Harry told the policeman that the man was wearing black jeans and a shirt. "His mask was a lady's stocking. His shoes were white sports shoes." Harry added. "You are a very careful boy," the policeman said. "Well done!" The next day the police caught the robber. They put him in a line with some other men.

Listen to the dialogue and complete the following sentences PRESENTER: Tell ,us about your new hook, Penny. PENNY: Well, it's another Captain Fish-Eye story for young children, about 6 years old. I enjoy writing about all Captain Fish-Eye's adventures at sea, and children love him and his amazing ship. PRESENTER: They don't feel it's boring to read the same stories again and again, do they? PENNY: No, never. PRESENTER: What type of books do young children enjoy most? PENNY: Young children really like funny stories--anything to make them laugh. And the pictures are very important too. Young children need books with bright colourful pictures. PRESENTER: You know, Walt Disney has made many famous fairy-stories into wonderful films. Is it better for children to see the films or to read the books? PENNY: I have to say, books are better. Of course, it's nice to see a happy children's film sometimes, but it isn't as good as reading a book. When children read stories, they see pictures in their heads and they use their minds much more. It's very important for them to do this when they're young. PRESENTER: I've heard that children in Britain read a lot of books. They read much more than children in many other countries. Do you know why? PENNY: Well, I think it's because British parents have always read to their children a lot. In most families, children listen to a story every evening before they go to sleep, and at school teachers read to their classes. Children learn to love books and want to read more and more.

答案:91.考点分析:数列的概念,组合问题。

解析:{}101091210,,,n a S S S k k k =-= (1)109S S =时,100a =;(2)100a ≠时,若10S 有10种可能性,9S 只能有9种可能性,反之成立。

AC AB AM μλ+=所以10a 共有109191⨯+=种。

二、选择题(每小题5分,满分20分)13、已知,,a b c 都是实数,则“,,a b c 成等比数列”是“2b ac =” 的( ) A 、充分不必要条件 B 、必要不充分条件 C 、充要条件 D 、既不充分也不必要条件 答案:A考点分析:等比数列的中项问题,学生易错。

可拓展一些,若,,a b c 为非零实数时的情况。

解析:充分性显然成立,0b c ==时,必要性不成立。

14.21,l l 是空间两条直线,α是平面,以下结论正确的是( )A.2121//,////l l l l 则一定有,如果αα,B.αα⊥⊥⊥1221,,l l l l 则一定有如果C.αα//,,1221l l l l 则一定有如果⊥⊥,D.2121,//,l l l l ⊥⊥则一定有如果αα 答案:D考点分析:本题主要是考察线面关系的概念辨析,我们通常可以借助手边的纸笔来帮助我们来分析,举反例是我们的常用思路。

解析:可以异面可以平行,可以相交也,,如果2121,////l l l l αα,故A 选项错误;ααα内,可能平行于可能在,如果1221,l l l l ⊥⊥,故B 、C 选项错误;所以本题选择D 。

15.已知函数0,00,,,,2)(133221321>+>+>+∈-=-x x x x x x R x x x e e x f xx ,且,那么)()()(321x f x f x f ++的值( )A.一定等于零 B 一定大于零 C 一定小于零 D 正负都有可能 答案:B考点分析:本题考查的函数的奇偶性和单调性,以及学生对条件的分析能力。

考查奇偶性、单调性和不等式的综合问题,即是021>+x x 的转化。

解析:根据表达式可以看出函数是一个奇函数,而且可通过定义说明函数是单调增函数,则0,00133221>+>+>+x x x x x x ,三个不等式可以转化为133221,,x x x x x x >->->,由函数为单调增函数得)(133221)(),()(),()(x f x f x f x f x f x f ->->->,有函数是奇函数,可知:0)()(,0)()(,0)()(133221>+>+>+x f x f x f x f x f x f ,三式相加可知答案为B 。

16.已知点M (a ,b )与点N (0,-1)在直线3x-4y+5=0的两侧,给出以下结论:1.3a-4b+5>0;2.当a>0时,a+b 有最小值,无最大值;31b a 22>+:;4.当a>0且a ≠1时,),(),的取值范围是(∞+∞+4349--1-a 1b 正确的个数是( ) A.1 B.2 C.3 D.4 答案:B考点分析:本题考查了点与直线的位置关系,对于两点在直线的两侧这个条件的分析。

另外对于1b a 22>+:和1-a 1b +的几何意义的理解。

通过分析条件和结论我们可以看出本题解决的是线性规划问题。

解析:由M 、N 在直线两侧可知:(3a-4b+5)(0+4+5)<0即:3a-4b+5<0,可知1错误;因为0<3a<4b-5,所以45b >,a+b 既无最大值也无最小值,可知2错误;易知坐标原点到直线3a-4b+5=0的距离d 为1,因为3a-4b+5<0,所以d>1,则1b a 22>+:,所以3正确;1-a 1b +表示的几何意义是点(a ,b )与(1,-1)连线的斜率k ,因为a>0,所以∈k ),(),(∞+∞4349-- ,所以4正确。

本题选择B.三、解答题(本大题满分76分)17.如图111-C B A ABC 是直三棱柱,底面ABC Δ是等腰直角三角形,且4==AC AB ,直三棱柱的高等于4,线段的中点为D ,线段BC 的中点为E ,线段1CC 的中点为F . (1)求异面直线EF AD ,所成角的大小; (2)求三菱锥AEF D -的体积。

答案:(1)32arccos(2)316 解析:(1)以A 为坐标原点,1,,AA AC AB 为z y x ,,轴,建立坐标系因为111-C B A ABC 是直三棱柱,底面ABC Δ是等腰直角三角形,且4==AC AB ,直三棱柱的高等于4,线段的中点为D ,线段BC 的中点为E ,线段1CC 的中点为F . 所以)2,4,0(),0,2,2(),4,2,2(),0,0,0(F E D A , (2,2,4),(2,2,2)AD EF ==-,设异面直线EF AD ,所成角的大小为q2cos 3AD EF AD EFq ·==·(2)D AEF F ADE V V --=底面ABC Δ是等腰直角三角形,线段BC 的中点为E所以⊥∴⊥,⊥1BC A A BC AE BC 面AED A 1,24=×21=,22=2=ΔDE AE S BC CE ADE11CB 11C B13D AEF F ADE V V CE--==创ADE S Δ=316考点分析:异面直线夹角求法,三棱锥体积求法18(本题满分14分,第(1)小题7分,第(2)小题7分)已知定义在⎪⎭⎫ ⎝⎛-22ππ,上的函数()x f 是奇函数,且当⎪⎭⎫⎝⎛∈20π,x 时,()1+=x tan x tan x f(1)求()x f 在区间⎪⎭⎫⎝⎛-22ππ,上的解析式(2)当实数m 为何值时,关于x 的方程()m x f =在⎪⎭⎫⎝⎛-22ππ,有解解:(1)令⎪⎭⎫ ⎝⎛-∈02,x π,则⎪⎭⎫⎝⎛∈-20π,x 代入()1+=x tan x tan x f 得()()()1+--=-x tan x tan x f , 又()x f 为奇函数,故()()()()11+-=+---=--=x tan xtan x tan x tan x f x f ,即求得()⎪⎪⎩⎪⎪⎨⎧⎪⎭⎫⎝⎛-∈+-⎪⎭⎫⎝⎛∈+=021201,x ,x tan x tan ,x ,x tan x tan x f ππ.

19、已知数列}{a n是首项等于161且公比不为1的等比数列,Sn是它的前n 项和,满足165423-=S S(1)求数列}{a n 的通项公式;(2)设0(log >=a a b nan且)1≠a ,求数列}{b n的前n 项和Tn的最值。

解:本题考查了等比数列的基本概念,的通项公式,前n 项和S n 的公式求法,根据条件165423-=S S ,直接代入公式即可求出公比,第二问考查了公比和对数的关系,实际上是一个等差数列,等差数列前n 项和的求法,公差大于0为增数列,小于0为减数列。
