7．Do you have a hobby？Something you look forward to spending your time with？Something you love to do？（36）D Or making model airplanes．Or making useful things out of waste materials．It could be a musical instrument that you love playing．Or singing and dancing．
There are many things that a hobby can give you，apart from an enjoyable time．Sashay was a shy boy but through his interest in model airplanes he learned the value of sticking to a task until it was finished．（37）G His model airplane club brought him to get into touch with similar persons．
Having a hobby helps you relax and get away from the routines of school．（38）C It gives you focus，self-dependence，confidence and builds your personality and this is an opportunity to lose yourself in an enjoyable activity，away from the pressure of school，so at the end of it，you feel relaxed and yet，mentally charged．
Your hobby defines（确定； 解释） you．（39）FAnd it also shows you what you are good at，and how far you can go，when you apply yourself．
（40）AA hobby is：Happiness：something which you look forward to doing．Opportunity：to develop your special and unique skills and celebrate them．Belief in yourself：makes you understand your strong advantages and improves your confidence．Best in you：brings out your best-for in each one of us there is a best that is only ours．YOU!gives you a unique character，and makes you YOU!

A．So go ahead and develop a hobby．
B．It proves your ability．
C．It gives you a break．
D．It could be collecting something．
E．Hobbies show your character．
F．It shows your special skills．
G．He learned to make friends for the first time．

6．HOW LIFE BEGAN ON THE EARTH
No one knows exactly how the earth began，as it happened so long ago．However，according to a （76）widelyaccepted theory，the universe began with a"Big Bang"that threw matter in all （77）directions．After that，atoms began to form and combine to create stars and other bodies．
For several billion years after the"Big Bang"，the earth was still just a （78）cloudof dust．What it was to become was uncertain until between 4.5and 3.8billion years ago when the dust settled into a solid globe．The earth became so （79）violentthat it was not clear whether the shape would last or not．It （80）explodedloudly with fire and rock．
A TRIP ON"THE TRUE NORTH"
Li Daiyu and her cousin Liu Qian were on a trip to Canada to visit their cousins in Montreal on the （81）Atlanticcoast．Rather than take the aeroplane all the way，they decided to fly to Vancouver and then take the train from west to east across Canada．The（82）thoughtthat they could cross the whole continent was exciting．
Their friend，Danny Lin，was waiting at the airport．He was going to take them and their baggage to catch"The True North"，the cross-Canada train．On the way to the station，he chatted about their trip．"You're going to see some great scenery．Going （83）eastward，you'll pass mountains and thousands of lakes and forests，as well as wide rivers and large cities．Some people have the （84）ideathat you can cross Canada in less than five days，but they forget the （85）factthat Canada is 5，500kilometres from coast to coast．

5．People often shake hands in the United States．American men shake hands with other men．American women often shake hands with men，and sometimes they shake hands with other women．Adults shake hands with children．And some people even teach their dogs to shake hands（11）CHow do they shake hands just long enough？Just hard enough？Here are four little rules to remember．
1．Use your right hand．
2．Use good eye contact （眼神交流）．Look at the person in the eye while you are shaking hands．
3．Don't shake too long．（12）BThen let go and pull your hand back toward you．
4．（13）DWhen a handshake is weak，Americans think the person may not be a hard worker or a good leader．When a handshake is too strong，Americans think the person is too rough （粗鲁的） or has bad manners．
（14）FThey shake hands when they meet for the first time．They shake hands to say congratulations．They shake hands when they meet after not seeing each other for a while．And they often shake hands when they say good-bye．In business，shaking hands shows agreement and honesty．
Handshakes are good everywhere．（15）E So make sure to shake plenty of hands．
A．Offer your hand first．
B．Shake for no more than three seconds．
C．How do people shake hands correctly？
D．Don't shake too strongly or too weakly．
E．It is not polite to refuse a person's hand．
F．When do people in the United States shake hands？
G．Make sure your hands aren't sweaty when you do this．

4．Muzak
The next time you go into a bank，a store，or a supermarket，stop and listen．What do you hear？（66）CIt's similar to the music you listen to，but it's not exactly the same．That's because this music was especially designed to relax you，or to give you extra energy．Sometimes you don't even realize the music is playing，but you react to the music anyway．
Quiet background music used to be called"elevator music"because we often heard it in elevators．But lately we hear it in more and more places，and it has a new name"Muzak"．About onethird of the people in America listen to"Muzak"every day．The music plays for 15 minutes at a time，with short pauses in between．It is always more lively between ten and eleven in the morning，and between three and four in the afternoon，when people are more tired．（67）B
  If you listen to Muzak carefully，you will probably recognize the names of many of the songs．Some musicians or songwriters don't want their songs to be used as Muzak but others are happy when their songs are chosen．Why？（68）F
  Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel．It has been proven that Muzak does what it is designed to do．Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background．（69）DSupermarket shoppers buy 38 percent more groceries．
（70）AThey say it's boring to hear the same songs all the time．But other people enjoy hearing Muzak in public places．They say it helps them relax and feel calm．One way or another．Muzak affects everyone．Some farmers even say their cows give more milk when they hear Muzak!

A．Some people don't like Muzak．
B．The music gives them extra energy．
C．Music is playing in the background．
D．Factory workers produce 13 percent more．
E．Muzak tends to help people understand music better．
F．They get as much as $4 million a year if their songs are used．
G．Muzak is played in most of the big supermarkets in the world．

3．Can you fall fast asleep at night？If not，you can try to drink a glass of hot milk．（36）E Still no luck？Try thinking about sheep jumping over a fence．Count them to yourself，"One，two，three，four…one hundred and ninety-five，one hundred and ninety-six…"
（37）C Should you take a sleeping pill？People who take pills often come to depend on the drugs．So you lie awake knowing that the new work day will soon arrive．If this happens to you forat least one month，you may have primary insomnia（失眠）．There are millions of you…us…around the world．
A new study has found that you might fall asleep quicker and stay asleep longer if you try"cerebral hypothermia"．No，cerebral hypothermia is not a complex medical process．（38）B
Two American professors led the study．They examined 12people who had insomnia and 12others who had no sleep problems．Each of them wore a soft plastic cap on their heads at bed time．
（39）D The researchers moved the water through the tubes and then changed the temperature of the water．Other studies showed that people who had trouble sleeping often had more chemical reactions in the front of their brains．The researchers thought lowering the temperature of the brain might help．
The first two nights of testing，the patients wore no water caps．During the next two nights，the caps were worn，but the water was not cooled．Then the researchers cooled the water a little for two nights．（40）G
The researchers found that the water caps did not help the insomnia patients until the temperature was about 14℃．Most of the patients fell asleep faster and slept better when the coolest water was moving around their heads．
A．Some say sheep counting might help．
B．It just means cooling down your brain．
C．It is late at night and you are still awake．
D．The caps had tubes inside filled with water．
E．If that does not work，listen to some soft，beautiful music．
F．They believe they have discovered something important that needs more research．
G．On the final two nights of the study，the temperature of the water was made much cooler．

2．Do you know what history is？It is everthing humans have done and thought．It is the story of events．It is the story of nation and persons．（36）CSo is the Hundread Years'War．So is the first airplane flight．
（37）A There are many sources．Some are oral．Some are written．We can learn of the past from one person's memory or from stories handed down through generations．We can see the past in a piece of stone．We see it in old paintings and photos．We read about the past in old records．They may be the ship's logs（日志） or church records．（38）EThey maybe journals of presidents．
It is impossible to record everything about an event or person．（39）FQuestion have to be asked．Answers must be found．Different accounts（叙述）of a single event need to be put togehther．
This is the job of historians．They look carefully at what they find．They search for causes of events．（40）B

A  How do we know about the past？
B  They also look for the results of history．
C  How people began writing is part of history．
D  History is all about the past．
E  They may be diaries of pioneers．
F  Facts must be carefully chosen to tell what happened．
G  What should people study？

1．If you find that your teacher is unfair to you，think about what is happening．Try to find out whether your teacher really dislikes you，or whether something else is going on．Here are some questions to ask yourself：
（36）BAsk your classmates if they are having trouble with the teacher，too．If they say yes，perhaps your teacher is to blame．
Are you working up to your ability？Maybe you got a C in your last test，and your teacher told you that you could do better．And the kid sitting beside you got a C，too（37）FIsn't this unfair？Well，it could be that your teacher knows that you could do better if you put more effort into it（38）G
（39）EThere's nothing wrong with being sensitive（敏感的），but if you react to criticism quite differently from others，this could be a reason why you think your teacher doesn't like you．
Does your teacher seem to act unfairly all the time，or just once in a while？Think about the harsh（苛刻的） things your teacher has done to you．Are these things happening every day，or just once or twice a month？If your teacher really hates you，you would probably be picked on（找茬）all the time．（40）C

A．Are you getting along well with your classmates．
B．Are you the only person being treated badly，or is your teacher rough on the whole class？
C．If your teacher has acted unfairly only a few times，then there's probably something else going on．
D．Are you interested in your lessons？
E．Are you more sensitive than other students？
F．But the teacher didn't say anything to him!
G．Teachers often grade students by different standards．

20．A．Arguments are pointless．
B．Your parents only want what's best for you．
C．Everyone's opinion matters only as much as you want them to．
D．You learn by doing．
E．Your emotions are under your control．
F．You aren't stuck in any situation．
Life is the greatest teacher
There always comes a moment when I wonder where I will end up and this moment always serves as a strong motivation for me to learn life lesson．I've learned a great many things，but these are the lessons that I wish I'd learned earlier：
（61）C
There was a time when everyone's opinion was mine as well．Whatever preferences I formerly held were dashed in the face of another's．This most likely came from a need to please others．
Remember that your opinion matters just as much as the next guy's，whether they make more money than you or are less popular than you．Everyone's opinion holds the same weight．
（62）E
Drama，chaos，and emotional unrest-these were what took up most of my time as a teenager．When everyone's obsessed with what's in and what's not，tempers flare； mine mostly．
If I had heard someone said rotten things behind my back，I'd erupt．Go crazy．Looking back on those tantrums now，I'm not too surprised．After all，when you have little self control，anything is possible．The lessons here is，remain aware of how you react．
（63）A
Will one small quarrel among friends decide the fate of the entire universe？In my world it felt like it．I just wanted so much to be right and for them so much to be wrong．But in the end，it only resulted in me wasting my time and in the other person storming off in frustration．
Is there really a point to arguing？Unless it's absolutely necessary，I've learned that it's better to hold your breath on things you can't control at all．
Arguing to change someone's mind is one of them．
（64）B
I'm not saying every parent wants what's best for you （there are outliers），but in general，parents do what they do for you in your best interest．My parents used to make me do the dishes，cook dinner，sweep the floors，mow the lawn，take out the garbage…the list goes on and on．And at every turn，I'd whine and complain．I'd eventually end up doing it．Now，I honestly see the value in having learned those skills．I can efficiently cook and clean up after myself．
（65）F
Whenever I'd lose a friend，get an awful grade，or disappoint my parents，I stewed in my own muck．Waiting for the bad moments to go away seemed to be the only solution．Fortunately，I know now that you don't have to be stuck in bad situations．You can go out and create better ones．
It all depends on perspective； on how you see the situation．Viewing everything as a learning experience makes life more pleasurable，even during the hard times．You aren't stuck．You can move on．
I'm glad to have learned these lessons the way I did．Each experience helped shape me to become a better person．I don't know if any young people are reading this，but if they are，I'd like to say this："Listen to life and it's experiences．Everyone goes through mostly the same things．"

19．（36）BYou probably think you will never be a top student．This is not necessarily so，however．Anyone can become a better student if he or she wants to．Here's how：
Plan your time carefully．When planning your work，you should make a list of things that you have to do．After making this list，you should make a schedule of your time．First your time for eating，sleeping，dressing，etc．Then decide a good，regular time for studying．（37）E A weekly schedule may not solve all your problems，but it will force you realize what is happening to your time．
Find a good place to study．Look around the house for a good study area．Keep this space，which may be a desk or simply a corner of your room，free of everything but study materials．No games，radios，or television．When you sit down to study，concentrate on the subject．
Make good use of your time in class．（38）CListening carefully in class means less work later．Taking notes will help you remember what the teacher says．
Study  regularly．When you get home from school，go over your notes，review the important points that your teacher is going to discuss the next day，read that material．（39）GIf you do these things regularly，the material will become more meaningful，and you'll remember it longer．
Develop a good attitude towards tests．The purpose of a test is to show what you have learned about a subject．They help you remember your new knowledge．The world won't end if you don't pass a test，so don't be over worried．
（40）AYou will probably discover many others after you have tried these．

A．There are other methods that might help you with your studying．
B．Maybe you are an average student．
C．Take advantage of class time to listen to everything the teacher says．
D．No one can become a top student unless he or she works hard．
E．Don't forget to set aside enough time for entertainment．
F．Make full use of class time to take notes of what the teacher says in class．
G．This will help you understand the next class．

18．No matter how old you are，your mom will always remain as one of the most important people in your life．Maybe you don't know how to express your appreciation and love to her on an ordinary day．（36）FHere are several things we can do this Mother's Day to show how much we appreciate and care for our mothers．
Give her flowers．（37）BYou can show your love to your mom by giving her flowers that match her personality．Or，if you do not know your mom's favorite，carnations（康乃馨） could be your best choice．
Cook for her．Mothers usually are the ones who cook for us．Your mom will absolutely love it if you surprise her by taking over the kitchen and cooking something for her．Just make sure you clean up afterwards．
（38）CYou can just do so describing how much your mother means to you．It can be very effective that your mom will keep them and always be reminded of how important she is to your lives as a family member．
Travel with her．Mothers work hard，so traveling can help her to relax and forget her problems．She will treasure the moment--wherever you go，just your presence．（39）G
Take her to a spa．Massages or spas（按摩保健） are for moms of all ages，and she will enjoy breaking the boredom of staying indoors the whole day．（40）E
Mother's Day is coming．It is a time to let Mom know she's special to you．

A．Remember her wedding anniversary．
B．Almost every girl appreciates flowers and so does your mother．
C．Write her a letter．
D．She remains the center of attention and respect for a child for a long time．
E．And this will offer your mom comfort and an increased sense of well-being．
F．However，Mother's Day is the special time when you can let her know how important she is to you．
G．A lot of us forget that the best gift to give her is ourselves．
