11.While Jennifer was at home taking an online exam for her business law class,a monitor (監(jiān)控器) a few hundred miles away was watching her every move.
Using a web camera equipped in Jennifer's Los Angeles apartment,the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room.Her Internet access was locked-remotely-to prevent Internet searches,and her typing style was analyzed to make sure she was who she said she was:Did she enter her student number at the same speed as she had in the past?Or was she slowing down?
In the battle against cheating,this is the cutting edge and a key to encourage honesty in the booming field of online education.The technology gives trust to the entire system,to the institution and to online education in general.Only with solid measures against cheating,experts say,can Internet universities show that their exams and diplomas are valid-that students haven't just searched the Internet to get the right answers.
Although online classes have existed for more than a decade,the concern over cheating has become sharper in the last year with the growth of"open online courses."Private colleges,public universities and corporations are jumping into the online education field,spending millions of dollars to attract potential students,while also taking steps to help guarantee honesty at a distance.
Aside from the web cameras,a number of other high-tech methods are becoming increasingly popular.Among them are programs that check students'identities using personal information,such as the telephone numbers they once used.
Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones.As in many university classes,term papers are scanned against some large Internet data banks for cheating.

41.Why was Jennifer watched in an online exam?D
A.To correct her typing mistakes.
B.To find her secrets in the room.
C.To prevent her from slowing down.
D.To keep her from dishonest behaviors.
42.The underlined expression cutting edge in Paragraph 3 is closest in meaning toA
A.a(chǎn)dvanced technique           
B.sharpening tool              
C.effective rule           
D.dividing line
43.For Internet universities,exams and diplomas will be valid ifB
A.they can attract potential students                          
B.they can defeat academic cheating
C.they offer students online help                               
D.they offer many online courses
44.Some programs can find out possible cheaters byA
A.checking the question answering speed                  
B.producing a large number of questions
C.scanning the Internet test questions                        
D.giving difficult test questions
45.Which of the following is the best title of this passage?C
A.The Advantages of Online Exams                          
B.The High-tech Methods in Online Courses
C.The Fight against Cheating in Online Education             
D.The War against the Booming of Online Education.

分析 本文為說(shuō)明文.網(wǎng)絡(luò)教育越來(lái)越受歡迎,但是在考試時(shí)如何防止考生作弊呢?網(wǎng)絡(luò)教育文憑的可信度與考試防作弊程序的有效性密切相關(guān).核實(shí)考生個(gè)人信息的程序以及監(jiān)控分析考生答題速度的程序都可以遏制網(wǎng)絡(luò)考試中出現(xiàn)的作弊現(xiàn)象.

解答 41.答案:D.推理判斷題.根據(jù)第二段倒數(shù)第二句"and her typing style was analyzed to make sure she was who she said she was:Did she enter her student number at the same speed as she had in the past?"可從本句得知監(jiān)控Jennifer的原因是為了確保她不作弊.故選D,就是不誠(chéng)實(shí)的行為.
42.答案:A.猜測(cè)詞義題.根據(jù)"a key to encourage"以及下一句的"the technology"可以知道答案.cutting edge與key是并列關(guān)系,同時(shí)二者都可以做到鼓勵(lì)誠(chéng)實(shí)行為.前面this所指代的為上文中提到的防作弊科學(xué)技術(shù),由此得知cutting edge應(yīng)該為advanced technique.
43.答案:B.細(xì)節(jié)理解題.根據(jù)第三段"Only with solid measures against cheating,experts say,can Internet universities show that their exams and diplomas are valid-that students haven"t just searched the Internet to get the right answers."可知只有通過(guò)強(qiáng)有力的手段來(lái)杜絕作弊,網(wǎng)絡(luò)大學(xué)的考試和文憑才有效,B項(xiàng)與之意思一致.
44.答案:A.細(xì)節(jié)理解題.根據(jù)最后一段的第一句"Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones."可知正確選項(xiàng)為A.此題易錯(cuò)選BD.其實(shí)選項(xiàng)A包含了BD選項(xiàng)內(nèi)容.通過(guò)生成大量的有難也有易的問(wèn)題,然后通過(guò)比較答題速度來(lái)辨別可能的作弊者.
45.答案:C.主旨大意題.文章主題句位于第三段第一句"In the battle against cheating,this is the cutting edge and a key to encourage honesty in the booming field of online education."可得知本文主要討論網(wǎng)絡(luò)課程的防作弊問(wèn)題,故選C.此外,文章多次出現(xiàn)cheating,屬于原詞重現(xiàn).

點(diǎn)評(píng) 閱讀這類文章要做到以下幾點(diǎn):
1.瀏覽試題,明確要求.
2.通讀全文,抓住主要內(nèi)容.
3.抓住中心思想和段落大意.
4.有針對(duì)性地仔細(xì)閱讀,找尋所需信息.
5.進(jìn)行合理的推理判斷.

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.

16.Before I had my son,I spent two years working with children with disabilities.I learned that shouting and threats of punishment would result in a disaster.Coming up against their behaviour could only make the job harder and their behaviour more extreme.I found something that worked,though.
There was a very naughty boy in the nursery and a teacher who was generally very confident with the children was asked to take charge of him.One day the boy joined a session in the room next to mine.His appearance created an atmosphere of tension.He spent the entire session running around,hitting and kicking,and destroying property.
I was in the craft room working with some other children when my co-worker told me that this boy's teacher was in tears,and could not get control of the situation.As we were talking,the boy ran in.I told my co-worker that I would take care of him.
I closed the door.He was full of energy,throwing things around and making a huge mess.But I could see that he was doing all these to annoy me.He needed connection,and this was the only way he knew how to ask for it.So I sat back down and kept quiet.Then he slowed down and began making a rocket.I talked to him about it.We continued like this for a few minutes before I slipped into the conversation:
"So what happened today?"
It was purely a question,no blame or anger in my tone.I believe that if I had criticized him,the gate that was slowly opening would have shut firmly closed.He told me that the teacher didn't let him do what he knew well due to safety but asked him to do what he disliked.He also admitted that he had enjoyed making her run around and saw it as a game.I explained that his teacher had not seen it as a game and was very upset.This again was stated simply as a fact.I suggested that next time he had a session,he talk about what he hoped to do at the start,which might be easier for everyone.He agreed and was quiet for a moment.Then he looked at me with tears in his eyes before quietly asking if he could go to find his teacher to apologize.

51.The boy made trouble for his teacher because heC.
A.was accused of destroying property
B.was told not to yell at other children
C.was made to do things against his will
D.was blamed for creating an air of tension
52.Why didn't the author do anything about the boy's bad behavior at firstA?
A.She didn't want to make it worse.
B.She didn't mind the huge mess at all.
C.She was tired of shouting and threats.
D.She hadn't thought of a coping strategy.
53.The author managed to get the boy to talk to her byD.
A.playing games with him
B.giving him a good suggestion
C.describing his teacher's feelings
D.a(chǎn)voiding making critical remarks
54.Why did the boy have tears in his eyes in the endB?
A.He was sorry about his reputation.
B.He was regretful about his behavior.

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.

5.In the fall of 1985.I was a bright-eyed ghl heading off to Howard University,aiming at a legal career and dreaming of sitting on a Supreme Court bench somewhere.Twenty-one years later I am later I am still a bright-eyed dreamer and one with quite a different tale to tell.
My grandma,an amazing woman,graduated from college an the age of 65.She was the first in our family to reach that goal.But one year after I started college,she developed cancer.I made the choice to withdraw from college to care for her.It meant that school and my personal dream would have to wait.
Then I got married with another dream:building my family with a combination of adopt and biological children.In 1999,we adopted our first son.To lay eyes on him was fantastic---and very emotional.A year later came our second adopted boy.Then followed son No.3.In 2003,I gave birth to another boy.
You can imagine how fully occupied I became,raising four boys under the age of 81.Our home was a complete zoo---a joyous zoo.Not surprising,I never did make it back to college full-time.But I never gave up on the dream either.I had only one choice:to find a way.That meant talking as few as one class each semester.
The hardest part was feeling guilty about the time I spent away from the boys.They often wanted me to stay home with them.There certainly were times I wanted to quit,But I knew I should set an example for them to follow through the rest of their lives.
In 2007,I graduated from the University of North Carolina.It took me over 21years to get my college degree!
I am not special,just single-minded.It always struck me that when you're looking at a big challenge from the outside it looks huge,but when you're in the midst of it,it just seems normal.Everything you want won't arrive in your life on one day.It's a process.Remember;little steps add up to big dreams.

41.When the author went to Howard University,her dream was to beC
A.a(chǎn) writer
B.a(chǎn) teacher
C.a(chǎn) judge
D.a(chǎn) doctor
42.Why did the author quit school in her second year of college?D
A.She wanted to study by herself.
B.She fell in love and got married.
C.She suffered from a serious illness.
D.She decided to look after her grandma.
43.What can we learn about the author from Paragraphs 4and 5?A
AShe was buy yet happy with her family life.
B.She ignored her guilty feeling for her sons.
C.She wanted to remain a full-time housewife.
D.She was too confused to make a correct choice.

A.Failure is the mother of success.
B.Little by little,one goes far.
C.Every coin has two sides.
