To Be Lucky，Be Prepared

I remember the exact moment I learned the principle of preparing for luck．

I was on the wrestling team．Now，if there’s one thing I can tell you about any sport，it is that wrestling is probably the sport that has the least  36  ．There are only two people out on the mat，so you cannot  37  it on your teammates or your coach．And guess what? There is no  38  because we do the whole thing indoors，so you can’t say，“It was raining”or“It was snowing．”It makes  39 to say wrestling is the sport with the least luck．

On our team were two world champions；one of them had been a world champion five times．

We  40  had five people who were national champions．One of them was a guy  41  the name

of John．

John had never been  42  in any high school wrestling competition that I could remember，  43  he was a national champion．There was nobody locally who could touch him．

One day，we  44  a match with our biggest opponent(對手)．John went out on the mat，and about a minute and 30 seconds into the match he tried to make a particular  45  ．He rolled over, and his opponent  46  him halfway through his roll．He was pinned  47  !

The match was over．

I remember on the bus on the way home，one of our teammates tried to  48  John by saying，

“Oh，he just got lucky.”And John said，“That’s so stupid．The opportunity presented itself，  49  he exploited it．”

We used to have this big sign in our wrestling room that the coach had  50  there：“Luck is what happens when opportunity  51  preparation.”

John’s opponent was prepared to exploit this opportunity．The probability of  52  John was not strong，and he knew it．But he paid attention to the  53  opportunity to present itself，and he defeated and pinned a five-time national champion．

In other words，the real  54  is“Be prepared!”It’s not just finding the opportunity；you  have to be prepared to  55  it．

36．A．1uck             B．risk         C．difficulty           D．opportunity

37．A．a(chǎn)ccuse           B．blame        C．doubt                D．keep

38．A．stress           B．injury       C．weather              D．standard

39．A．judgment         B．progress     C．sense                D．way

40．A．a(chǎn)lso             B．even             C．only             D．once

41．A．under            B．for              C．in               D．by

42．A．hurt             B．chosen           C．trained          D．defeated

43．A．a(chǎn)lthough         B．because          C．unless           D．until

44．A．went for         B．waited for       C．fought for       D．played for

45．A．sign             B．step             C．task             D．move

50．A．set              B．put              C．left             D．used

51．A．meets            B．suits            C．gets             D．fits

52．A．striking         B．beating          C．knocking         D．controlling

53．A．equal            B．exact            C．rest             D．right

第三部分：閱讀理解(共20小題；每小題2分，共40分)

閱讀下列短文，從每題所給的A、B、C、D四個選項中，選出最佳選項。

A

My teacher held up a piece of broken glass and asked，“Who broke this window?”Thirty boys tried to think about not only what they had done，but also what our teacher may have found out．She seldom became angry，but she was this time．

“Oh，” I thought．I was the one who broke the window．It was caused by a naughty throw of a baseball．If I admitted guilt，I would be in a lot of trouble．How would I be able to pay for a big window like that? I didn’t even get an allowance.“ My father is going to have a fit，”I thought．I didn’t want to raise my hand，but some force much stronger than I was pulled it skyward．I told the truth.“I did it．”It was hard enough to say what I had．

My teacher took down a book from one of our library shelves and I had never known my teacher to strike a student，but I feared she was going to start with me．

“I know how you like birds，”she said as she stood looking down at my guilt-ridden face．“Here is that field guide about birds that you are constantly checking out．It is yours now．It’s time we got a new one for the school anyway．You will not be punished as long as you remember that I am not rewarding you for your misdeed，I am rewarding you for your truthfulness.”

I couldn’t believe it! I wasn’t being punished and I was getting my own bird field guide―the very one that I had been saving up money to buy.

All that remains of that day is my memory and the lesson my teacher taught me．That lesson stays with me every day and it will echo forever.

56．From the story，we can learn that the boy       .

A．didn’t break the window on purpose

B．lacked the strength to admit his guilt

C．tried to think about what he had done

D．didn’t know what the teacher would find out

57．If the boy admitted guilt，he thought he would NOT       ．

A．be punished by the teacher           B．make his father angry

C．pay for the broken window            D．get a bird field guide

58．Which of the following best describes the changes in the boy’s feelings?

B．Frightened ― Amazed ― Proud．

C．Regretful ― Guilty ― Excited．

D．Nervous ― Afraid ― Satisfied．

59．What is the lesson the boy’s teacher taught him?

A．Every coin has two sides．           B．Honesty is always valued．

C．Bad luck never comes alone．         D．It’s never too late to be careful．

B

ANY VOLUNTEERS？

MORE WAYS TO GET INVOLVED WHILE HAVING GREAT FUN

60．All of the volunteers will      in the four activities．

A．teach young kids                 B．have a lot of fun

In Britain and other countries，young people sometimes take a“gap year，”a year off between high school and college．This idea never gained a big following in America．Recent news reports have suggested that interest may be growing，though there are no official numbers．

Charles Deacon，Dean of Admissions at Georgetown University in Washington，D．C．，

estimates that in the current first-year class of 1600 students，only about 25 decided to take a year off．He says this number hasn’t changed much over the years．

Mr．Deacon says the most common reason for taking a“gap year”is to have a chance to travel，but he says international students may take a“gap year”to meet requirements at home for military duty．

Some high school graduates see a year off as a chance to recover after twelve years of required education，but it can also give students a chance to explore their interests．Students hoping to be doctors，for example，could learn about the profession by volunteering in a hospital．

Many colleges and universities support gap-year projects by permitting students to delay their admission. Experts say students can grow emotionally and intellectually as they work at something they enjoy．

The Harvard admissions office has an essay on its Web site called“Time Out or Burn Out for the Next Generation”．It praises the idea of taking time off to step back，think and enjoy gaining life experiences outside the pressure of studies．It also notes that students are sometimes admitted to Harvard or other colleges partly because they did something unusual with that time．

Of course，a“gap year”is not for everyone．Students might miss their friends who go on directly to college，and parents might worry that their children will decide not to go to college once they take time off．Another concern is money．A year off，away from home，can be costly．

Holly Bull’s job is to specialize in helping students plan their“gap year”．She notes that several books have been written about this subject．She says these books along with media attention and the availability of information on the Internet have increased interest in the idea of a year off，and she points out that many gap-year programs cost far less than a year of college．

63．What is the passage mainly about?

A．More and more American students are choosing to take a year off．

B．If you want to go to an American university，take a“gap year”first．

C．It is likely that taking a“gap year”is becoming popular in America．

D．Americans hold different opinions towards students’taking a“gap year”．

64．How many reasons for students’taking a“gap year”are mentioned in the passage?

A．2．              B．3．              C．4．             D．5．

65．The essay“Time Out or Burn Out for the Next Generation”suggests that      ．

A．every student must take a“gap year” before applying for a famous university

B. some famous universities encourage students to gain more life experiences

C．taking a“gap year”can make students free from life learning

D．the stress of studies does harm to the students’health

66．What can we learn from the passage?

A．Books and media have contributed to the students’interest in school learning．

B．Charles Deacon doesn’t support the idea of the students’taking a“gap year”．

C．Parents might disagree with the program，concerned about their children’s future．

D．Experts agree taking a year off will benefit the students emotionally and physically．

I was working with a client who was completely burned out on her career and life and then ready for a career change．As we were talking，she said，“I just wish I had meaningful work．I don’t feel like I am making a difference．I am just wasting my life．”This is the theme I hear most often from clients who have been in the workforce awhile．All of us want to feel like we are making a difference．We want to believe our work means something．The problem comes in defining“meaningful work．”What is it? That answer is different for everyone．For some meaningful work might be helping others organize their office．For others it may mean making a million dollars．

What really matters is how you see it．What is meaningful work to you? Take out a piece of

paper and answer these questions．How do you define meaningful work? When do you feel like you are really making a difference? What work have you done so far that feels the most meaningful? Write down whatever comes to mind．

It is very easy to start judging yourself as being selfish. Stop！Allow yourself to be honest. The fact is when Picasso painted，he was doing it because he liked to paint. He was not thinking，“Oh，I hope this brings joy to others’lives.”He painted because he wanted to. When Beethoven composed, he did it because he loved music. Even scientists searching for a cure for cancer are immersed in their work because it fascinates them.

It is easy to downplay the importance of work that feels meaningful. I remember Tony Robbins told a story of talking with the owner of a major company. The man said to Tony．“I wish I could do what you do because it makes such a difference in people’s lives.”Tony said.“ You’ve got to be kidding! Look at what a difference you make. You provide work，health insurance and security for thousands of people!”Don’t underestimate the value you provide.

Take a look at what you have written about meaningful work. Do you see any themes? How do you wish to contribute to this world？Whatever you choose，remember that the greatest gift you can give is to find work that makes you feel fulfilled and joyful. Honor your preferences because giving your gifts to the world，whatever they look like，is the most meaningful action you can ever take.

67．Which should come first to see whether you are doing something meaningful?

    A．What is meaningful work to you?

    B．Where can you find meaningful work?

    C．How do you wish to contribute to the world?

    D．How can you make a difference in your work?

68．What does the writer mean by mentioning the famous people?

    A．Famous people are selfish to start work for themselves.

    B．Doing meaningful work requires our interest in it.

    C．Interest is the best teacher in learning.

    D．Honesty makes for the greatest people.

69．When you downplay the value of your work，you tend to think it is       .

  A．quite different                B．very successful

  C．not meaningful                 D．less important

70．According to the passage，what meaningful job does the writer advise us to take?

    A．The one which is popular in society.

    B．The one which brings you profits.

    C．The one which wins you fame.

    D．The one which interests you.

71．The article is intended to       .

A．explain the most important aspect in changing one’s career

B．a(chǎn)dvise taking a preferable action to find meaningful work

C．suggest we should show confidence and talent in work

D．show us how to give our greatest gift to society

Have you pulled your car up to the gas pump lately and been shocked by the high price of gas? As the pump clicked past $50，$60，$70 or even $80,maybe you

thought  about  trading  in  your car for something that gets better mileage．Or maybe you’re worried that your car is contributing to the greenhouse effect.

The car industry has the technology to address these concerns. It’s the hybrid car. There are a lot of hybrid models on the market these days，and most automobile manufacturers have announced plans to manufacture their own versions.

To be useful to you，a car must meet certain minimum requirements. The car should be able to drive at least 300 miles(482 km)between refueling，be refueled quickly and easily，and keep up with the other traffic on the road.

A gasoline car meets these requirements，but produces a relatively large amount of pollution and generally gets poor gas mileage. An electric car，however，produces almost no pollution，but it can only go 50 to 100 miles(80 to 161 km)between charges，and the problem has been that the electric car is very slow and inconvenient to recharge．

The hybrid is a compromise. It significantly increases the mileage and reduce the emissions of a gas-powered car while overcoming the shortcomings of an electric car．

Most hybrid cars on the road right now are gasoline-electric hybrids，although French car maker Citroen has two diesel-electric hybrid（柴油電動混合）cars in the works.

In fact，hybrid vehicles are all around us．For example，an electric bike is a type of hybrid because it combines the power of electricity with the pedal power of its rider. Most of the locomotives we see pulling trains are diesel-electric hybrids．Cities like Seattle have diesel-electric buses ― these can draw electric power from overhead wires or run on diesel when they are away from the wires. Submarines are also hybrid vehicles ― some are nuclear-electric and some are diesel-electric．Any vehicle that combines two or more sources of power that can directly or indirectly provide propulsion power is a hybrid．

72．From the passage，we know the hybrid cars can do the following EXCEPT            ．

    A．going 50 to 100 miles between charges

    B．recharging quickly and conveniently

    C．reducing environmental pollution

    D．driving farther between refueling

73．The writer didn’t directly tell us            in the passage．

    A．what the shortcomings of gasoline cars and electric ones are

    B．what solutions have been found to bring gas prices down

    C．what basic features people expect their cars to have

    D．what car drivers are concerned about today

74．What can be learned from the last paragraph?

    A．Developing hybrid vehicles is a new trend．

    B．Only modern cities can provide hybrid cars．

    C．A hybrid is more powerful and energy saving．

    D．What general characteristics a hybrid vehicle has．

75．What may be the best title for the passage?

    A．Hybrid Car ― Best Seller in the Car Market

    B．Hybrid Car ― Reputation in the Car Industry

    C．Hybrid Car ― A Better Choice for the Future

D．Hybrid Car ― A New Technical Invention
