AAll over the world mothers and fathers teach their children manners.Other children may have mann ers that are not like yours.There are all kinds of manners.Many years ago, children who had good manners were seen and not heard.They kept quite quiet if grown­ups were talking.Today, well­mannered childr en have more freedom.Sometimes good manners in one place are bad manners in other places.Suppose you are a visitor in the land of Mongolia.Some friends ask you to eat with them.What kind of manners do they want you to have? They want you to give a loud “burp” after you finish eating.Burping would show that you like their food.In some countries, if you give a loud burp, you are told to say “excuse me, please.”In many places people like to eat together.But in some parts of Polynesia，it is bad manners to be seen eating all together.People show good manners by turning their backs on others while they eat.What are manners like in an East African town? The people try not to see you.They are being polite.You may see a friend.He may not see you at all.If you are polite, you will sit down beside him.You will wait until he finishes what he is doing.Then he will talk to you.Suppose you visit a friend in Arabia.You should walk behind the other tents until you come to his tent.If you pass in front of the other tents, you will be asked into each one.The people will ask you to eat with them.And it is bad manners if you say no.Manners are different all over the world.But it is good to know that all manners begin in the same way that people need ways to show that they want to be friends.21．People turn their backs on others while they eat in ________.A．MongoliaB．an East African townC．some parts of PolynesiaD．Arabia22．In an East African town, the people try not to see you.This is because ________.A．they are busy doing thingsB．they don’t want to talk with youC．it is good mannersD．they are waiting for you to talk with them23．Which of the following statements is TRUE?A．In Mongolia, you should say “excuse me” when you give a burp after dinner.B．Children with good manners are quiet.C．You should not walk behind the tents in Arabia.D．Manners are different all over the world.24．Sometimes good manners in one place are bad manners in other places.Which should be the supporting paragraph(s) to the idea?A．the fourth one B．the fifth one C.the sixth oneD．all of aboveBBody language or，as it is also known，non­verbal communication，is about all the things that people say and do without using words.Research suggeststhat more than 70% of communication occurs without people having to say a single word.Like language，the way we communicate non­verbally varies across cultures.But，unlike language，it can be very difficult to find out what the non­verbal rules are.It’s all very well known that there are differences in the ways that cultures work，but what can you do to try to prepare yourself for living and surviving in another culture?I think you’ve got two things to think about.I personally don’t fully accept the idea of “When in Rome，do as the Romans do”．I don’t thin k people expect you to completely adopt all of the things that they do.What I think that people would like is that you agree and understand it and that you do your best.One of the things you can do is actually explain to the other culture，saying，“Well，you know，actually we don’t normally kiss in my culture，so it’s a bit uncomfortable.” But then do your best，so it’s a learning process.Well，kissing is just one of many different ways of interaction that you need to know.You can get into difficult or embarrassing or even worse situations if you don’t know it.Eye contact，tone of voice，how close you stand，any touching，how many times you kiss，a long handshake，a short handshake it can go on and on.So I think，yes，you do need to get these correct and you need to have good observation skills.25．Body language is ________.A．not necessary B．not popularC．not worthless D．not involving words26.From the passage，it can be inferred ________.A．only grown­ups have body languageB．body language can be understood by all the people all the timeC．only the same body language has the same meaning all over the world D．body languages are not the same because their cultures are different27．The passage is mainly to tell readers ________.A．body language is importantB．to find out the rules of body languageC．when in Rome，do as the Romans doD．to learn good observation skills28．According to the author，we know that ________.A．to learn body language，you should watch people and observe what they doB．to learn a language，you should prepare yourself for living in another cultureC．when you learn a language，you must know the differences of different culturesD．to know body language，you should adopt all that other cultures doCThe Roar of NatureTsunamiThe 9.2 magnitude earthquake which caused the tsunami in the Indian Ocean on Boxing Day last year occurred at 7∶58 a．m.,95 miles off the west coast of Aceh，Indonesia.Eighteen minutes later,10­metre high waves crashed ashore along a 500 mile­long stretch of Aceh.Two hours later the tsunami hit Thailand and Malaysia and then Burma，Bangladesh，India，the Maldives，Sri Lanka，Kenya and Somalia.The final death toll is thought to be about 280,000，with tens of thousands more listed as missing.More than 1.8 million people lost their homes.What Is Tsunami?A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes，volcanic eruptions，or even the collision of meteorites(陨星)．Tsunamis are also incorrectly known as tidal waves，but unlike tidal waves they are not caused by changes in the tides.They are also most common around the edge of the Pacific，where more thanhalf of the world’s volcanoes are found.These seismic surges c an attack coastlines，often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried 180m inland.Wave PowerA tsunami can have a wavelength in excess of 100km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea.Over the deep Pacific Ocean，a tsunami travels at about 800Kph.If an earthquake happened in Los Angeles，a tsuna mi could hit Tokyo quicker than you could fly between the cities by jet.Strange Animal BehavioursTen days before giant waves slammed into Sri Lanka and India coastlines，wild and domestic animals seemed to know what was about to happen and fled to safety.Elephants screamed and ran for higher ground.Dogs refused to go outdoors.Zoo animals rushed into their shelters and could not be enticed(勾引) to come back out.29．What does the first part of the passage mainly tell us?A．The great speed of a tsunami.B．The serious destruction caused by the great power of a tsunami.C．The countries which were struck by a tsunami.D．The number of deaths caused by a tsunami.30．All the following can cause a tsunami EXCEPT ________.A．changes of the tidesB．volcanic eruptionsC．collision of meteoritesD．magnitude earthquakes31．Which of the following is a characteristic of a tsunami?A．Having a lot of small waves linked together.B．The waves of a tsunami can be found in the distance.C．The power of the waves becomes stronger and stronger as a tsunami travels.D．The waves of a tsunami travel extremely fast.32．What can we learn from the strange animal behaviours?A．Animals are cleverer than human beings.B．More animals should be raised to prevent a tsunami.C．They might be used to predict a tsunami.D．Animals in the zoos should be watched carefully.DAs any homemaker who ha s tried to keep order at the dinner table knows，there is far more to family meal than food.Sociologist Michael Lewis has been studying 50 families to find out just how much more.Lewis and his co­workers carried out their study by videotaping(录像)the families while they ate ordinary meals in their own homes.They found that parents with small families talk actively with each other and their children.But as the number of children gets larger，conversation gives way to the parents’ efforts to control the loud n oise they make.That can have an important effect on the children.“In general，the more question­asking the parents do，the higher the children’s IQ scores，”Lewis says.“And the more children there are，the less question­asking there is.”The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings(兄弟姐妹)．Lewis found that in families with three or four children，dinner conversation is likely to center on the oldest child，who has the most to talk about，and the youngest，who needs the most attention.“Middle children are invisible，”says Lewis.“When you see someone get up from the table and walk around during dinner，chances are it’s the middle child.”There is，however，one thing that stops all conversation an d prevents anyone from having attention.“When the TV is on，”Lewis says，“dinner is a non­event.”33．The writer’s purpose in writing the text is to ________.A．show the relationship between parents and childrenB．teach parents ways to keep order at the dinner tableC．report on the findings of a studyD．give information about family problems34．Parents with large families ask fewer questions at dinner because ________.A．they are busy serving food to their childrenB．they are busy keeping order at the dinner tableC．they have to pay more attention to younger childrenD．they are tired out having prepared food for the whole family35．By saying “Middle children are invisible” in Paragraph 3，Lewis means that middle children ________.A．have to help their parents to serve dinnerB．get the least attention from the familyC．are often kept away from the dinner tableD．find it hard to keep up with other children第二节(共5小题；每小题2分，满分10分)根据短文内容，从短文后的选项当选出能填入空白处的最好选项。

论中国古代家庭教育思想王建军因血缘关系而萌发的亲情是家庭成员交往的自然基础和人伦准则，从亲亲敬长的血缘亲情中提升出孝悌仁爱等道德，这是古代家庭教育乃至道德教育具有生命力的根源所在.孔子说，孝悌之德的培养并非停留于孝顺之举的行动层面，而应追求尊老敬长情感的升华。

因此从儿童本身的生活体验出发来培养其尊老敬长的情感，最为自然最为贴切。

家庭教育以此为基本出发点，既符合人的自然本性，又切合儿童的生活和情感的体验.古人对孝悌内涵的界定并未停留在情感的层面,而是力图将这一情感导入尊卑贵贱的家族制度的轨道,将对家长的孝顺之情转化成对宗法等级制度的服从。

在宗法制度的影响及古代思想家们的包装下，这种血缘关系的不同却成为家庭成员内部主从、尊卑的客观基础，成为家庭成员之间贵贱亲疏的理论依据。

这种血缘宗法制度给古代家庭教育贴上了等级制度的标签,遵守和服从这一文化秩序成为古代家庭教育的根本要求,古代家庭中的儿童备受其害。

可这压抑儿童天性有损家庭和睦的家庭教育主张却能在古代社会大行其道,历久不衰，其根本原因是古代家庭教育所倡行的孝悌之德适应了封建社会的发展需要。

孔子曾说过：“夫孝，始于事亲，中于事君，终于立身。

”萌发于血缘之情的孝悌之德不仅具有“事亲”的效用，而且具有“事君”的效用，这是由封建社会的政治结构所决定。

这样,培养孝悌之德不仅成为“齐家”的需要，而且成为“国治"的基本素质要求.正由于古代家庭结构与社会政治结构的这一同构性,将孝悌之德政治化和制度化便成为封建政治家们孜孜以求的目标。

身居这一文化环境中，任何家庭都难以摆脱这一教育模式的张力。

(2)由已知，得k BC ＝m 2－m －22，且x A －x B ＝m －2.①当m －2＝0，即m ＝2时，直线AB 的斜率不存在，此时k BC ＝0，于是AB ⊥BC ；②当m －2≠0，即m ≠2时，k AB ＝1m －2， 由k AB ·k BC ＝－1，得1m －2·m 2－m －22＝－1， 解得m ＝－3.综上，可得实数m 的值为2或－3.21、如图2-5所示，四棱锥P —ABCD 中，底面ABCD 是矩形，PA⊥平面ABCD ，M 、N 分别是AB 、PC 的中点，PA=AD=a.求证:（1）MN∥平面PAD ；（2）平面PMC⊥平面PCD.证明：如图所示，(1)设PD 的中点为E ，连结AE 、NE ，由N 为PC 的中点,知EN21DC. 又四边形ABCD 是矩形，∴DC AB. ∴EN 21AB.又M 是AB 的中点， ∴EN AM.∴AMNE 是平行四边形.∴MN∥AE.而AE ⊂平面PAD ，NM 平面PAD,∴MN∥平面PAD. (2)∵PA=A D ，∴AE⊥PD.又∵PA⊥平面ABCD ，CD ⊂平面ABCD ，∴CD⊥PA，而CD⊥AD，∴CD⊥平面PAD.∴CD⊥AE.∵PD∩CD=D，∴AE⊥平面PCD. ∵MN∥AE,∴MN⊥平面PCD.又MN 平面PMC ，∴平面PMC⊥平面PCD.22、已知点P (2，－1)．(1)求过点P 且与原点O 的距离为2的直线的方程；(2)求过点P 且与原点O 的距离最大的直线的方程，并求出最大距离；(3)是否存在过点P 且与原点O 的距离为6的直线？若存在，求出该直线的方程；若不存在，请说明理由．解：(1)①当直线的斜率不存在时，方程x ＝2符合题意．②当直线的斜率存在时，设斜率为k ，则直线方程为y ＋1＝k (x －2)，即kx －y －2k －1＝0. 根据题意，得|2k ＋1|k 2＋1＝2，解得k ＝34. 则直线方程为3x －4y －10＝0.故符合题意的直线方程为x －2＝0或3x －4y －10＝0.(2)过点P 且与原点的距离最大的直线应为过点P 且与OP 垂直的直线．则其斜率k ＝2，所以其方程为y ＋1＝2(x －2)， 即2x －y －5＝0. 最大距离为 5.(3)不存在．理由：由于原点到过点(2，－1)的直线的最大距离为5，而6>5，故不存在这样的直线．。

AAll over the world mothers and fathers teach their children manners.Other children may have mann ers that are not like yours.There are all kinds of manners.Many years ago, children who had good manners were seen and not heard.They kept quite quiet if grown­ups were talking.Today, well­mannered childr en have more freedom.Sometimes good manners in one place are bad manners in other places.Suppose you are a visitor in the land of Mongolia.Some friends ask you to eat with them.What kind of manners do they want you to have? They want you to give a loud “burp” after you finish eating.Burping would show that you like their food.In some countries, if you give a loud burp, you are told to say “excuse me, please.”In many places people like to eat together.But in some parts of Polynesia，it is bad manners to be seen eating all together.People show good manners by turning their backs on others while they eat.What are manners like in an East African town? The people try not to see you.They are being polite.You may see a friend.He may not see you at all.If you are polite, you will sit down beside him.You will wait until he finishes what he is doing.Then he will talk to you.Suppose you visit a friend in Arabia.You should walk behind the other tents until you come to his tent.If you pass in front of the other tents, you will be asked into each one.The people will ask you to eat with them.And it is bad manners if you say no.Manners are different all over the world.But it is good to know that all manners begin in the same way that people need ways to show that they want to be friends.21．People turn their backs on others while they eat in ________.A．MongoliaB．an East African townC．some parts of PolynesiaD．Arabia22．In an East African town, the people try not to see you.This is because ________.A．they are busy doing thingsB．they don’t want to talk with youC．it is good mannersD．they are waiting for you to talk with them23．Which of the following statements is TRUE?A．In Mongolia, you should say “excuse me” when you give a burp after dinner.B．Children with good manners are quiet.C．You should not walk behind the tents in Arabia.D．Manners are different all over the world.24．Sometimes good manners in one place are bad manners in other places.Which should be the supporting paragraph(s) to the idea?A．the fourth one B．the fifth one C.the sixth oneD．all of aboveBBody language or，as it is also known，non­verbal communication，is about all the things that people say and do without using words.Research suggests that more than 70% of communication occurs without people having to say a single word.Like language，the way we communicate non­verbally varies across cultures.But，unlike language，it can be very difficult to find out what the non­verbal rules are.It’s all very well known that there are differences in the ways that cultures work，but what can you do to try to prepare yourself for living and surviving in another culture?I think you’ve got two things to think about.I personally don’t fully accept the idea of “When in Rome，do as the Romans do”．I don’t thin k people expect you to completely adopt all of the things that they do.What I think that people would like is that you agree and understand it and that you do your best.One of the things you can do is actually explain to the other culture，saying，“Well，you know，actually we don’t normally kiss in my culture，so it’s a bit uncomfortable.” But then do your best，so it’s a learning process.Well，kissing is just one of many different ways of interaction that you need to know.You can get into difficult or embarrassing or even worse situations if you don’t know it.Eye contact，tone of voice，how close you stand，any touching，how many times you kiss，a long handshake，a short handshake it can go on and on.So I think，yes，you do need to get these correct and you need to have good observation skills.25．Body language is ________.A．not necessary B．not popularC．not worthless D．not involving words26.From the passage，it can be inferred ________.A．only grown­ups have body languageB．body language can be understood by all the people all the timeC．only the same body language has the same meaning all over the worldD．body languages are not the same because their cultures are different27．The passage is mainly to tell readers ________.A．body language is importantB．to find out the rules of body languageC．when in Rome，do as the Romans doD．to learn good observation skills28．According to the author，we know that ________.A．to learn body language，you should watch people and observe what they do B．to learn a language，you should prepare yourself for living in another culture C．when you learn a language，you must know the differences of different cultures D．to know body language，you should adopt all that other cultures doCThe Roar of NatureTsunamiThe 9.2 magnitude earthquake which caused the tsunami in the Indian Ocean on Boxing Day last year occurred at 7∶58 a．m.,95 miles off the west coast of Aceh，Indonesia.Eighteen minutes later,10­metre high waves crashed ashore along a 500 mile­long stretch of Aceh.Two hours later the tsunami hit Thailand and Malaysia and then Burma，Bangladesh，India，the Maldives，Sri Lanka，Kenya and Somalia.The final death toll is thought to be about 280,000，with tens of thousands more listed as missing.More than 1.8 million people lost their homes.What Is Tsunami?A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes，volcanic eruptions，or even the collision of meteorites(陨星)．Tsunamis are also incorrectly known as tidal waves，but unlike tidal waves they are not caused by changes in the tides.They are also most common around the edge of the Pacific，where more than half of the world’s volcanoes are found.These seismic surges c an attack coastlines，often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried 180m inland.Wave PowerA tsunami can have a wavelength in excess of 100km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea.Over the deep Pacific Ocean，a tsunami travels at about 800Kph.If an earthquake happened in Los Angeles，a tsuna mi could hit Tokyo quicker than you could fly between the cities by jet.Strange Animal BehavioursTen days before giant waves slammed into Sri Lanka and India coastlines，wild and domestic animals seemed to know what was about to happen and fled to safety.Elephants screamed and ran for higher ground.Dogs refused to go outdoors.Zoo animals rushed into their shelters and could not be enticed(引诱) to come back out.29．What does the first part of the passage mainly tell us?A．The great speed of a tsunami.B．The serious destruction caused by the great power of a tsunami.C．The countries which were struck by a tsunami.D．The number of deaths caused by a tsunami.30．All the following can cause a tsunami EXCEPT ________.A．changes of the tidesB．volcanic eruptionsC．collision of meteoritesD．magnitu de earthquakes31．Which of the following is a characteristic of a tsunami?A．Having a lot of small waves linked together.B．The waves of a tsunami can be found in the distance.C．The power of the waves becomes stronger and stronger as a tsunami travels.D．The waves of a tsunami travel extremely fast.32．What can we learn from the strange animal behaviours?A．Animals are cleverer than human beings.B．More animals should be raised to prevent a tsunami.C．They might be used to predict a tsunami.D．Animals in the zoos should be watched carefully.DAs any homemaker who ha s tried to keep order at the dinner table knows，there is far more to family meal than food.Sociologist Michael Lewis has been studying 50 families to find out just how much more.Lewis and his co­workers carried out their study by videotaping(录像)the families while they ate ordinary meals in their own homes.They found that parents with small families talk actively with each other and their children.But as the number of children gets larger，conversation gives way to the parents’ efforts to control the loud n oise they make.That can have an important effect on the children.“In general，the more question­asking the parents do，the higher the children’s IQ scores，”Lewis says.“And the more children there are，the less question­asking there is.”The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings(兄弟姐妹)．Lewis found that in families with three or four children，dinner conversation is likely to center on the oldest child，who has the most to talk about，and the youngest，who needs the most attention.“Middle children are invisible，”says Lewis.“When you see someone get up from the table and walk around during dinner，chances are it’s the middle child.”There is，however，one thing that stops all conversation and prevents anyone from having attention.“When the TV is on，”Lewis says，“dinner is a non­event.”33．The writer’s purpose in writing the text is to ________.A．show the relationship between parents and childrenB．teach parents ways to keep order at the dinner tableC．report on the findings of a studyD．give information about family problems34．Parents with large families ask fewer questions at dinner because ________.A．they are busy serving food to their childrenB．they are busy keeping order at the dinner tableC．they have to pay more attention to younger childrenD．they are tired out having prepared food for the whole family35．By saying “Middle children are invisible” in Paragraph 3，Lewis means that middle children
