10．It seemed like there were quarrels every evening．My children were always fighting over something．They never agreed on who had last washed the dishes，or who had last picked the，TV program．I was tired of constantly being a judge．
One day，I thought over what my life was like before marriage．I recalled my high school days when the terms"Odd（奇數(shù)的）"day/and"Even"day meant something．My class schedule changed by turns between"O"days and"E"days．On O days I might attend Physics and Maths．And on E days I'd go to another elective class，such as First aid or Art．
So I explained our new system to the children．"Jolee，you were born first，"I said．"Is one an odd number or all even one？"
"It's odd，Mom．"
"And A1，you arrived second．Is two odd or even？"
"It's even，Mom．"
"Ok，so Jolee，from now on，every odd day is automatically your own special day．That means you get to pick what to watch，or which board game to play．Al，the same applies to you on even days．"
He thought about it a minute，then said，"But there are more odd days than even ones in some months．Jolee will get‘her day'two times in a row when a month ends in 31，and the next one begins with a one．"
"True，"I said，"but that also means she'11 be taking the smelly，disgusting rubbish out，washing the dishes，and doing other less-enjoyable things two more days in a row，and you won't．It's part of life's give-and-take．"
For the first few days after that，whenever one kid shouted，"Mom!"I'd just call out，"Whose day is it？"That settled it．Soon．the quarrelling ended．
Ah，the complete joy of peace and quiet！
41．What made the writer bored？C
A．Programs on TV．            
B．Washing the dishes．
C．Her children's quarreling． 
D．Her dull marriage．

A．The writer's life before marriage was happy．
B．The writer's grades were，good at high schoo1．
C．The writer's class schedule changed every day．
D．The writer's favorite subject was Physics and Maths．
43．Which of the following statements is true according to the text？D
A．Al is cleverer than her sister Jolee．   
B．Jolee likes doing housework better．
C．Neither of the children likes the new system．
D．Both children have their privileges in turn．

6．Wealth starts with a goal saving a dollar at a time．Call it the piggy bank strategy（策略）．There are lessons in that time-honored coin-saving container．
  Any huge task seems easier when reduced to baby steps．I f you wished to climb a 12，000-foot mountain，and could do it a day at a time，you would only have to climb 33feet daily to reach the top in a year．If you want to take a really nice trip in 10years for a special occasion，to collect the 15，000cost，youhavetosave3.93a day．If you drop that into a piggy bank and then once a year put $1，434in a savings account at 1% interest rate after-tax，you will have your trip money．
  When I was a child，my parents gave me a piggy bank to teach me that，if I wanted something，I should save money to buy it．We associate piggy banks with children，but in many countries，the little containers are also popular with adults．Europeans see a piggy bank as a sign of good fortune and wealth．Around the world，many believe a gift of a piggy bank on New Year's Day brings good luck and financial success．Ah，but you have to put something in it．
  Why is a pig used as a symbol of saving？Why not an elephant bank，which is bigger and holds more coins？In the Middle Ages，before modern banking and credit instruments，people saved money at home，a few coins at a time dropped into a jar or dish．Potters（制陶工） made these inexpensive containers from an orange-colored clay（黏土） called"pygg，"and folks saved coins in pygg jars．The Middle English word for pig was"pigge"．While the Saxons pronounced pygg，referring to the clay，as"pug"，eventually the two words changed into the same pronunciation，sounding the"i"as in pig or piggy．As the word became less associated with the orange clay and more with the animal，a clever potter fashioned a pygg jar in the shape of a pig，delighting children and adults．The piggy bank was born．
  Originally you had to break the bank to get to the money，bringing in a sense of seriousness into savings．While piggy banks teach children the wisdom of saving，adults often need to relearn childhood lessons．Think about the things in life that require large amounts of money---college education，weddings，cars，medical care，starting a business，buying a home，and fun stuff like great trips．So when you have money，take off the top 10%，put it aside，save and invest wisely．

41．What is the piggy bank strategy？D．
A．Paying 1% income tax at a time．
B．Setting a goal before making a travel plan．
C．Aiming high even when doing small things．
D．Putting aside a little money regularly for future use．
42．Why did the writer's parents give him a piggy bank as a gift？C．
A．To delight him with the latest fashion．B．To encourage him to climb mountains．
C．To help him form the habit of saving．D．To teach him English pronunciation．
43．What does then underlined word"something"（Paragraph 3）most probably refer to？A．
A．Money                               B．Gifts
C．Financial success                     D．Good luck
44．The piggy ban originally wasB．
A．a(chǎn) potter's instrument                    B．a(chǎn) cheap clay container
C．a(chǎn)n animal-shaped dish                     D．a(chǎn) pig-like toy for children
45．The last paragraph talks aboutC．
A．the seriousness of educating children         
B．the enjoyment of taking a great trip
C．the importance of managing money          
D．the difficulty of starting a business．

3．In 1974，after filling out fifty applications，going through four interviews，and winning one offer，I took what I could get-a teaching job at what I considered a distant wild area：western New Jersey．My characteristic optimism was alive only when I reminded myself that I would be doing what I had wanted to do since I was fourteen-teaching English．
School started，but I felt more and more as if I were in a foreign country．Was this rural area really New Jersey？My students took a week off when hunting season began．I was told they were also frequently absent in late October to help their fathers make hay on the farms．I was a young woman from New York City，who thought that"Make hay while the sun shines"just meant to have a good time．
But，still，I was teaching English．I worked hard，taking time off only to eat and sleep．And then there was my sixth-grade class-seventeen boys and five girls who were only six years younger than me．I had a problem long before I knew it．I was struggling in my work as a young idealistic teacher．I wanted to make literature come alive and to promote a love of the written word．The students wanted to throw spitballs and whisper dirty words in the back of the room．
In college I had been taught that a successful educator should ignore bad behavior．So I did，confident that，as the textbook had said，the bad behavior would disappear as I gave my students positive attention．It sounds reasonable，but the text evidently ignored the fact that humans，particularly teenagers，rarely seems reasonable．By the time my boss，who was also my taskmaster，known to be the strictest，most demanding，most quick to fire inexperienced teachers，came into the classroom to observe me，the students exhibited very little good behavior to praise．
My boss sat in the back of the room．The boys in the class were making animal noises，hitting each other while the girls filed their nails or read magazines．I just pretended it all wasn't happening，and went on lecturing and tried to ask some inspiring questions．My boss，sitting in the back of the room，seemed to be growing bigger and bigger．After twenty minutes he left，silently．Visions of unemployment marched before my eyes．
I felt mildly victorious that I got through the rest of class without crying，but at my next free period I had to face him．I wondered if he would let me finish out the day．I walked to his office，took a deep breath，and opened the door．
He was sitting in his chair，and he looked at me long and hard．I said nothing．All I could think of was that I was not an English teacher； I had been lying to myself，pretending that everything was fine．
When he spoke，he said simply，without accusation，"You had nothing to say to them．"
"You had nothing to say to them．"he repeated．"No wonder they are bored．Why not get to the meat of literature and stop talking about symbolism．Talk with them，not at them．And more important，why do you ignore their bad behavior？"We talked．He named my problems and offered solutions．We role-played．He was the bad student，and I was the forceful，yet，warm，teacher．
As the year progressed，we spent many hours discussing literature and ideas about human beings and their motivations．He helped me identify my weaknesses and strengths．In short，he made a teacher of me by teaching me the reality of Emerson's words："The secret to education lies in respecting the pupil．"
Fifteen years later I still drive that same winding road to the same school．Thanks to the help I received that difficult first year，the school is my home now．

55．It can be inferred from the story that in 1974C．
