1．(2012·四川资阳中学高一期中)关于合力与其两个分力的关系，下列说法正确的是() A．合力的大小一定大于小的分力，小于大的分力B．合力的大小随分力夹角的增大而增大C．合力的大小一定大于任意一个分力D．合力的大小可能大于大的分力，也可能小于小的分力解析：选D.根据力的平行四边形定则，两个共点力的合力大小不一定大于小的分力，如图甲所示，也不一定小于大的分力，如图乙所示，所以A、C不正确；合力的大小随夹角的增大而减小，如图丙所示，所以B不正确；仅D正确．2．关于共点力，下列说法中正确的是()A．作用在一个物体上的几个力，如果它们力的作用点在同一点上，则这几个力是共点力B．作用在一个物体上的几个力，如果它们力的作用线相交于同一点，则这几个力是共点力C．共点力一定作用在物体的同一点上D．平行四边形定则只适用于共点力合成答案：ABD3．两个共点力，一个是40 N，另一个等于F，它们的合力是100 N，则F的大小可能是() A．20 N B．40 NC．80 N D．160 N解析：选C.因(F－40 N)≤100 N≤(F＋40 N)故60 N≤F≤140 N，应选C项．4.图2－5－9设有三个力同时作用在质点P上，它们的大小和方向相当于正六边形的两条边和一条对角线，如图2－5－9所示，这三个力中最小的力的大小为F，则这三个力的合力大小等于() A．3F B．4FC．5F D．6F解析：选A.由图中几何关系，F3＝F cos60°＋F＋F cos60°＝2F，而F1与F2的夹角为120 °，其大小均为F，故F1、F2合力大小为F，且沿F3方向，因此F1、F2、F3的合力大小为3F.故选项A正确．5.图2－5－10(创新题)如图2－5－10所示，天鹅、大虾和梭鱼一起想把一辆大车拖着跑，他们都给自己上了套，天鹅伸着脖子要往云里钻，大虾弓着腰儿使劲往前拉，梭鱼一心想往水里跳，它们都在拼命地拉，结果大车却一动不动．则下列说法正确的是()A．它们的合力一定比大虾的拉力大B．它们的合力与大车所受的摩擦力一定平衡C．它们的合力可能为零D．大车所受的合力一定为零解析：选D.因为大车一动不动，由平衡条件知，大车所受的合力一定为零，D项对；它们的合力与大车所受其他力(包括重力、支持力、摩擦力)的合力一定平衡，B项错；由题图可知它们的力不在同一平面内，合力不可能为零，与大虾的拉力也无法比较大小，故A、C均错．一、选择题1.图2－5－11如图2－5－11所示，物体受到大小相等的两个拉力作用，每个拉力都是20 N，夹角是60°，则这两个力的合力大小为()A．30 N B．35 NC．40 N D．20 3 N解析：选D.由于两个力大小相等，且夹角为60°，所以作出的平行四边形是菱形，可用计算法求得合力F，如图所示，F＝2F1cos30°＝3F1＝20 3 N.2．已知三个分力的大小依次为3 N、5 N、9 N，关于这三个分力的合力大小，下面给出了四个值：①0 N②1 N③5 N④18 N．其中可能的是()A．只有②③B．只有①②③C．只有②③④D．只有①②④解析：选A.如果这三个力中任意两个力的和大于第三个力，则合力的范围是：0≤F≤F1＋F2＋F3；如果这三个力中两个最小的力的和小于第三个力，则合力的最小值不可能为零.3 N ＋5 N<9 N，因此①不可能，3 N＋5 N＋9 N＝17 N为最大值，④不可能，故选A.3．如图2－5－12为两个共点力的合力F随两分力的夹角θ变化的图像，则这两个分力的大小分别为()图2－5－12A．1 N和4 N B．2 N和3 NC．1 N和5 N D．2 N和4 N解析：选B.由图像知，两力方向相同时，合力为5 N，即F1＋F2＝5 N；方向相反时，合力为1 N，即F1－F2＝1 N．故F1＝3 N，F2＝2 N，B正确．4．物体同时受到同一平面内的三个力的作用，下列几组力的合力可能为零的是()A．5 N、7 N、8 NB．5 N、1 N、3 NC．1 N、5 N、10 ND．10 N、10 N、10 N解析：选AD.对于A组，5 N和7 N的合力F所在的范围是：2 N≤F≤12 N,8 N处在合力范围内，A组合力可能为零，同理可知D组合力也可能为零．5．如图2－5－13所示，猎人非法猎猴，用两根轻绳将猴子悬于空中，猴子处于静止状态，以下说法正确的是()图2－5－13A．猴子受到两个力的作用B．人将绳子拉得越紧，猴子受到的合力越大C．人将绳子拉得越紧，猴子受到合力越小D．人将绳子拉得越紧，猴子受到绳子的拉力越大解析：选D.猴子受重力、两段绳子的拉力，两段绳子的拉力的合力大小等于重力，两段绳子的拉力的合力大小不变，人将绳子拉得越紧，两段绳子的夹角越大，猴子受到绳子的拉力越大，A、B、C错误，D正确．6.图2－5－14(创新题)在“3·11”日本大地震的一次抢险救灾工作中，一架沿水平直线飞行的直升机利用降落伞匀速向下向灾区群众投放救灾物资，假设物资的总重量为G1，圆顶形降落伞的重量为G2，有8条相同的拉线一端与运动员相连(拉线重量不计)，另一端均匀分布在伞面边缘上，如图2－5－14所示(图中没有把拉线都画出来)，每根拉线和竖直方向都成30°角．那么每根拉线上的张力大小为()A.3(G1＋G2)12B.G1G28C.G14D.3G112解析：选D.8根拉线在竖直方向的分力的合力等于运动员和他身上装备的总重量G1，即8F cos30°＝G1，则F＝3G1 12.7．平面内作用于同一点的四个力若以力的作用点为坐标原点，有F1＝5 N，方向沿x轴的正方向；F2＝6 N，沿y轴正方向；F3＝4 N，沿x轴负方向；F4＝8 N，沿y轴负方向，以上四个力的合力方向指向()A．第一象限B．第二象限C．第三象限D．第四象限解析：选D.方向相反的F1和F3合成的合力F′大小为1 N，方向沿x轴正方向；方向相反的F2与F4合成的合力F″大小为2 N，方向沿y轴负方向．则F′与F″合成的合力方向在第四象限．8.图2－5－15两个共点力的合力F 与两力之间夹角θ的关系如图2－5－15所示，则两力大小是( )A ．7 N 8 NB ．3.5 N 2.5 NC ．5 N 8 ND ．9 N 4 N解析：选B.由题图可知，当两个力的夹角为0°时，合力为6 N ，此时合力最大．当两个力的夹角为180 °时，两个力的合力为1 N ．此时合力最小．由公式F max ＝F 1＋F 2和F min ＝|F 1－F 2|可知：3.5 N 、2.5 N 符合题意，答案为B.9．(2012·郑州外国语学校高一检测)两个共点力的合力为F ，如果它们之间的夹角θ固定不变，使其中一个力增大，则( )A ．合力F 一定增大B ．合力F 的大小可能不变C ．合力F 可能增大D ．合力F 可能减小解析：选BCD.当θ为锐角(或直角)时，则随着其中的一个力增大，合力也增大，如图甲所示．当两个分力之间的夹角θ为钝角时，由图乙所示的平行四边形可知，当F a 逐渐增大为F a 1、F a 2、F a 3时，其合力由原来的F 1变为F 2、F 3、F 4，它们可能小于F 1，可能等于F 1，也可能大于F 1，A 选项是合力F 一定增大，所以A 错误，应该是合力F 可能增大，可能减小，也可能不变．即B 、C 、D 正确．10．两个共点力同向时合力为a ，反向时合力为b ，当两个力垂直时，合力大小为( )A.a 2＋b 2B.(a 2＋b 2)/2C.a ＋bD.(a ＋b )/2解析：选B.设两个共点力分别为F 1、F 2，由题意可知，F 1＋F 2＝a ，F 1－F 2＝b .所以F 1＝a ＋b 2，F 2＝a －b 2；两个力垂直时合力F ＝F 21＋F 22＝(a 2＋b 2)/2，所以B 正确． 二、非选择题11．将橡皮筋的一端固定在A 点，另一端拴上两根细绳，每根细绳分别连着一个量程为5 N 、最小刻度为0.1 N 的弹簧测力计．沿着两个不同的方向拉弹簧测力计．当橡皮筋的活动端拉到O 点时，两根细绳相互垂直，如图2－5－16所示．这时弹簧测力计的读数可从图中读出．图2－5－16图2－5－17(1)由图可读得两个相互垂直的拉力的大小分别为________N 和________N(只需读到0.1 N)．(2)在方格纸(见图2－5－17)上按作图法的要求画出这两个力及它们的合力．解析：从图中可知，弹簧测力计最小分度为0.1 N ，因此，竖直向下的弹簧测力计读数为2.5 N ，水平向右的弹簧测力计读数为4.0 N ．因为读数2.5 N 、4.0 N 均是0.5 N 的整数倍，因此，选方格纸中一个小方格的边长表示0.5 N ，应用平行四边形定则，即可画出两个力以及它们的合力，如图所示．合力F ＝4.7 N.答案：(1)4.0 2.5(2)如图所示12.图2－5－18如图2－5－18所示，一条小船在河中向正东方向行驶，船上挂起一风帆，帆受侧向风作用，风力大小为100 N ，方向为东偏南30°，为了使船受到的合力恰能沿正东方向，岸上一人用一根绳子拉船，绳子取向与河岸垂直，求风力和绳子拉力的合力大小及绳子拉力的大小． 解析：如图所示，以F 1、F 2为邻边作平行四边形，使合力F 沿正东方向，则F ＝F 1cos30°＝100×32 N ＝50 3 N. F 2＝F 1·sin30°＝100×12N ＝50 N. 答案：50 3 N 50 N。

They also go toconcerts, climb mountains, go fishing, skate and swim. Theycollect everything from books to butterflies and from boxes to stamps.People follow hobbies because these activities offer enjoyment, friendship, knowledge and relaxation. Sometimes they even make money by following a hobby. Hobbies help people relax after hard work, and provide a balance between work and play. Hobbies also offer interesting activities for persons who are retired. Anyone, rich or poor, old or young, can follow an interesting hobby.Hobbies can also help a patient to keep healthy. Doctors have found that hobbies are useful in helping patients (病人) recover from illness. Hobbies give patients who can’t move around something to do, and provide interests that keep them from thinking about themselves. Many hospitals treat (治疗) patients by having them take up interesting hobbies. Anyone, old or young, sick or well, rich or poor, can follow a good hobby, in spite of his age, health or money.In early times, most people were too busy making a living to have many hobbies. But some persons who had spare time did enjoy hobbies. People today have more time than ever before for hobbies. Machines have now reduced much time that people must spend on their jobs. More people retire at an earlier age than before. Those who have developed hobbies never need to worry about what to do with their newly-found free time hours.Sir William Osler, a famous Canadian doctor expressed the value of hobbies bysaying, “No man is really happy or safe without a hobby. ”1.

Mall rats shop until they drop in the hundreds of stores under one roof.People like malls for many reasons. They feel safe because malls have police stations of private security guards. Parking is usually free, and the temperature inside is always fine. (1)The newest malls have beautiful rest areas with water falls and tall green trees.The largest mall in the United States is the Mall of America in Minnesota. It covers 4. 2 million square feet. It has 350 stores, eight night clubs, and a seven-acre park! There are parking spaces for 12, 750 cars. About 750, 000 people shop there every week.The first indoor mall in the United States was built in 1965 in Edina, Minnesota. People love doing all their shopping in one place. More malls are built where people come to do many things. They shop, of course, they also eat in food courts that have food from all over the world. They see movies at the theatres. Some people even get their daily exercise by doing the new sport of “mall walking”. Others go to malls to meet friends.In some malls, people can see a doctor or a dentist and even go to the church. In other words, people can do just about everything in malls. (2)现在人们甚至能在他们喜欢的商场居住。

It was happiness.One weekend, I went to visit my grandparents in the countryside. On my way home a car ran me over and cut off my arms because of its high speed.Several days later when I woke up in the hospital, I realized I had to spend the rest of my life1arms. How sad I felt at that time！Even I was full of fears.2 slowly I knew I had to face the fact and got over it. I couldn't get my arms back even though I 3 every day.However, it's easier said than done. It took me nearly half a year to get out of the sadness4.I got so much from my past story. From then on, I could treat my life with a5mind. But in our daily life, I often see my classmates get6about little things: They get a bad grade on a test; their bus comes7; they don't have a mobile phone but 8 have, and so on. But I only enjoy life. I was lucky to realize from an accident: It is a waste of our life to focus on what you have 9. We should always think of what we have. So why are so many people unhappy？Someone may say, "My whole life would improve 10I have a new car." But when you get the car, what will happen？For a whole week you are walking on air. Then you go right back to being unhappy.Happiness depends on what we have！It's in our heart. It's a state of mind. Even though you own the whole world, you may still feel unhappy. Happiness comes from mastering the art of appreciating(感激)and taking pleasure in what you really have.（1）A . withB . withoutC . for（2）A . OrB . ButC .

But “How are you?”is also a very unusual question.It's a question that often doesn't need an answer.Theperson who asks“How are you?”hopes to hear the answer“Fine”,even if the person's friend isn't fine.The reason is that “How are you?”isn't really a question and “Fine”isn't really an answer.They are simply other ways of saying“Hello”or “Hi”.Sometimes,people also don't say exactly what they mean.For example,when someone Asks “Do you agree?”,the other person might think,“No, I disagree.I think you're Wrong...”But it isn't very polite to disagree so strongly,so the other person migh t say“I'm not sure.”It's a nicer way to say that you don't agree with someone.People also don't say exactly what they are thinking when they finish talking with other people.For example,many talks over the phone finish when one person say “I've to go now.”Often,the person who wants to hang up gives and excuse:“Someone's at the door.”“Something is burning on the stove.”The excuses might be real,or not. Perhaps the person who wants to hang up simply doesn't want to talk any more,but it isn't polite to say that. The excuse is more polite,and it doesn't hurt the other person.Whether they are greeting each other,talking about an idea,of finishing a talk,people don't say exactly that they are thinking.It's an important way that people try to be nice to each other,and it's part of the game of language.（1）When a person in America asks“How are you?”,he or she wants to hear " "A . How are you?B . HelloC . I don't know.D . Fine（2）When a person disagree with someone,it is polite to say“”A . You are wrong.I disagree.B . I'm not sure.C . I'm sure I disagree.D . No, I disagree.（3）A polite way to finish talk is to say“”A . You have to go now.B . I want to hang up.C . I have to go now.D . I don't want to talk any more.（4）When a person says“I've to go now.Someone's at the door.”,the person may be.A . giving an excuseB . hurting someone's feelingC . illD . asking you a question（5）The rule of the game of language is probably .A . “Always say what you mean”B . “Don't disagree with people.”C . “Never say exactly what you're thinking.”D . “Be polite.”四、填空题 (共3题；共11分)18. （1分）We could see the ________ (happy) on his face after he heard the bad news.19. （5分）Jim's father and Cindy's father are .

1．下面四个结论：①偶函数的图像一定与y轴相交；②奇函数的图像一定过原点；③偶函数的图像一定关于y轴对称；④既是奇函数又是偶函数的一定是y＝0(x∈R)．其中正确的个数是()A．1B．2C．3 D．4解析：选A.可结合我们已学过的函数及奇、偶函数的图像特征来判断．偶函数的图像一定关于y轴对称，但不一定与y轴相交，如函数y＝x0，y＝x－2都是偶函数，但它们的图像不与y轴相交，故①错误，③正确；奇函数的图像关于原点对称，但不一定过原点，如y＝x－1，故②错误；若函数y＝f(x)既是奇函数又是偶函数，由定义可得f(x)＝0，但未必x∈R，如x∈(－1,1)，只要其定义域关于原点对称即可，故④错误，所以，四个结论中只有③正确，故选A.2．(2011·高考上海卷)下列函数中，既是偶函数，又在区间(0，＋∞)上单调递减的函数是() A．y＝x－2B．y＝x－1C．y＝x2D．y＝1 3 x解析：选A.∵y＝x－1和y＝13x都是奇函数，故B、D错误．又y＝x2虽为偶函数，但在(0，＋∞)上为增函数，故C错误，y＝x－2＝1x2在(0，＋∞)上为减函数，且为偶函数，故A满足题意．3．下图是根据y＝f(x)绘出来的，则表示偶函数的图像是图中的________．(把正确图像的序号都填上)解析：观察四个图像可以看出，只有图(3)关于y轴对称，其相应的函数是偶函数．答案：(3)4．若函数y＝(a2－3a－3)x2为幂函数，则a的值为________．解析：根据幂函数的定义，若函数y＝(a2－3a－3)x2为幂函数，则x2的系数必为1，即a2－3a－3＝1，所以a2－3a－4＝0，解得a＝－1或a＝4.答案：－1或4[A级基础达标]1．函数f (x )＝1x－x 的图像关于( )A ．y 轴对称B ．直线y ＝－x 对称C ．坐标原点对称D ．直线y ＝x 对称解析：选C.∵f (x )的定义域是(－∞，0)∪(0，＋∞)，关于原点对称，又f (－x )＝1－x－(－x )＝－⎝⎛⎭⎫1x －x ＝－f (x )，∴f (x )是奇函数，它的图像关于原点对称，故选C.2．已知函数f (x )(x ∈R)是偶函数，则下列各点中必在函数y ＝f (x )图像上的是( ) A ．(－a ，f (a )) B ．(－a ，－f (a )) C ．(－a ，－f (－a )) D ．(a ，－f (a ))解析：选A.因为函数f (x )(x ∈R)是偶函数，所以，若点(a ，f (a ))在函数y ＝f (x )的图像上，由偶函数的图像关于y 轴对称可知，点(a ，f (a ))关于y 轴的对称点(－a ，f (a ))必在函数图像上．3．(2012·宝鸡调研)函数y ＝1－x 2|x ＋3|－3是( )A ．偶函数不是奇函数B ．奇函数不是偶函数C ．奇函数又是偶函数D ．非奇非偶函数解析：选B.y ＝1－x 2|x ＋3|－3的定义域为{x |－1≤x ≤1且x ≠0}，关于原点对称，又当x ∈[－1,0)∪(0,1]时，x ＋3>0.∴y ＝1－x 2x是奇函数，故选B.4．比较大小(填“>”“<”或“＝”)：(1)⎝⎛⎭⎫250.5________⎝⎛⎭⎫130.5； (2)(－π)3________(－3)3.解析：(1)因为幂函数y ＝x 0.5在区间[0，＋∞)上是增函数，又25>13，所以⎝⎛⎭⎫250.5>⎝⎛⎭⎫130.5. (2)因为幂函数y ＝x 3在区间(－∞，＋∞)上是增函数，又－π<－3，所以(－π)3<(－3)3. 答案：(1)> (2)<5．幂函数y ＝(k 2－2k －2)x 1－k 在(0，＋∞)上是减函数，则k ＝________.解析：∵y ＝(k 2－2k －2)x 1－k 是幂函数， ∴k 2－2k －2＝1， ∴k ＝3或k ＝－1，当k ＝－1时，y ＝x 2在(0，＋∞)上是增函数，不合题意，舍去．当k ＝3时，y ＝x －2在(0，＋∞)上是减函数， 故k ＝3. 答案：36．已知幂函数f (x )＝x α的图像经过点A ⎝⎛⎭⎫12，2.(1)求实数α的值；(2)求证：f (x )在区间(0，＋∞)内是减函数．解：(1)∵f (x )＝x α的图像经过点A ⎝⎛⎭⎫12，2， ∴⎝⎛⎭⎫12α＝2，即2－α＝122，解得α＝－12. (2)证明：由(1)可知，f (x )＝12-x ，任取x 1，x 2∈(0，＋∞)，且x 1<x 2，则x 2－x 1>0，∴f (x 1)－f (x 2)＝121-x －122-x＝1x 1－1x 2＝x 2－x 1x 1x 2＝x 2－x 1x 1x 2·()x 1＋x 2>0，即f (x 1)>f (x 2)． ∴f (x )＝12-x在区间(0，＋∞)内是减函数．[B 级 能力提升]7．幂函数y ＝x α中α的取值集合C 是⎩⎨⎧⎭⎬⎫－1，0，12，1，2，3的子集，当幂函数的值域与定义域相同时，集合C 为( )A.⎩⎨⎧⎭⎬⎫－1，0，12B.⎩⎨⎧⎭⎬⎫12，1，2 C.⎩⎨⎧⎭⎬⎫－1，12，1，3 D.⎩⎨⎧⎭⎬⎫12，1，2，3 解析：选C.根据幂函数y ＝x －1，y ＝x 0，y ＝12-x ，y ＝x ，y ＝x 2，y ＝x 3的图像和解析式可知，当α＝－1，12，1,3时，相应幂函数的值域与定义域相同．8．(2012·合肥质检)已知偶函数f (x )在区间(0，＋∞)单调增加，则满足f (2x －1)<f ⎝⎛⎭⎫13的x 取值范围是( )A.⎝⎛⎭⎫13，23B.⎣⎡⎭⎫13，23C.⎝⎛⎭⎫12，23D.⎣⎡⎭⎫12，23 解析：选A.f (x )在(0，＋∞)为增，则在(－∞，0)为减．f (2x －1)<f ⎝⎛⎭⎫13，∴－13<2x －1<13，∴13<x <23. 9．(2012·南昌质检)幂函数y ＝21322-+p p+x (p ∈Z)为偶函数，且f (1)<f (4)，则实数p ＝________. 解析：由f (1)<f (4)可知幂函数在(0，＋∞)上为增函数．∴－12p 2＋p ＋32>0，∴p 2－2p －3<0.∴(p －3)(p ＋1)<0，∴－1<p <3.又∵p ∈Z ，当p ＝0时，或p ＝2时，y ＝32x 不是偶函数，p ＝1，y ＝x 2适合题意． 答案：110．已知函数f (x )＝ax 2＋bx ＋3a ＋b 为偶函数，其定义域是[a －1,2a ]，求f (x )的值域． 解：∵f (x )＝ax 2＋bx ＋3a ＋b 是[a －1,2a ]上的偶函数，∴⎩⎪⎨⎪⎧a －1＋2a ＝0，b ＝0.∴⎩⎪⎨⎪⎧a ＝13，b ＝0.∴f (x )＝13x 2＋1.∴f (x )＝13x 2＋1在⎣⎡⎦⎤－23，23上的值域是⎣⎡⎦⎤1，3127. 11．(创新题)已知定义在R 上的函数f (x )满足：f (x ＋y )＝f (x )＋f (y )＋2xy (x ＋y )(x ，y ∈R)，f (1)＝－1.(1)求f (0)和f (－2)的值；(2)若f (5)＝m ，试用m 表示f (－5)；(3)试判断f (x )的奇偶性(要写出推理过程)． 解：(1)取x ＝y ＝0得f (0)＝2f (0)，∴f (0)＝0.取x＝y＝1得f(2)＝2f(1)＋2×2＝2.取x＝2，y＝－2得f(0)＝f(2)＋f(－2)，∴f(－2)＝－2.(2)取x＝5，y＝－5得f(0)＝f(5)＋f(－5)．∴f(－5)＝－m.(3)取y＝－x得f(0)＝f(x)＋f(－x)，∴f(－x)＝－f(x)．从而f(x)是奇函数．。
