I’ve spent most of my career as a traveling salesman, so I know that battling homesickness is an occupational hazard(職業(yè)病).But one year, my little girl Jeanine gave me the cure 21 for my homesickness.

It was a toy 22 ,which stood about five inches tall. 23 to its left wing was a little sign saying “I Love My Day!”

On my next 24 ,I threw the penguin in my suitcase. That night when I  25 home, Jeanine was 26 that the penguin had disappeared. “Honey, I 27 him along.” I explained on the phone.

From then on, the penguin came with me ?as  28 as my shaving kit and we made friends 29  the way. Once a customs agent at New York’s Kennedy Airport dug the penguin out of my suitcase and, 30 it up, said, “That’s the most 31 thing that I have ever seen in all my years on the job.

I drove a hundred miles to get it, and when I arrived at midnight, the penguin was 36 at the front desk. In the lobby(大廳),tired business travelers looked on at the reunion, with a touch of (一點兒) 37 ,I think.

Jeanine is in college now, and I don’t travel as much. The penguin sits on my dresser, a 38 that love is a wonderful traveling 39 .All those years on the road, it was the one thing I 40 left home without.

Lions are more animals called prides. Prides can be as small as 3 or family animals and truly social in their own communities. They usually live in groups of 15 or as big as 40 animals. In a pride, lions hunt prey, raise cubs(幼獸),and defend their territory together.

In prides the females do most of the hunting and raising of the cubs. Usually all of the females in the pride are related-mothers, daughters, grandmothers, and sisters.

Each pride will generally have no more than two adult males. While the females usually live with the pride for life, the males often stay for only two to four years. After that they go off on their own or are evicted(逐出)by other males who take over the pride.

When a new male becomes part of the pride, it is not unusual for him to kill all the cubs, ensuring that all future lions born in the pride will have his genes.

The main job of males in the pride is defending the pride’s territory. A male’s loud roar, usually heard after sunset, can carry as far as eight kilometers. The roar warns off intruders(入侵者)and help round up lost members of the pride.

Hunting is generally done in the dark by the females. They often hunt in groups of two or three. After the kill the males usually eat first, females next,and young lions get what’s left.

  41．What is a pride?

A．a(chǎn) group of lions.                                    B．A territory of lions.

C．form 3 to 15                                                 D．from 15 to 50

43．Which of the following provide most of the labor?

  A．The males.                                             B．only the mothers.

C．The young lions.                                    D．The females.

Wendy Gallegos writes  "concer" on the board. One of her students raises her hand.

"Ms. Gallegos, you should have written 'conocer' instead,"  she said,  referring to the Spanish verb for "to know".

Gallegos looks at the board,   smiles and quickly erases her mistake.

"You see, I have taught you so well, you pick up on my mistakes," she said with a laugh.

To Gallegos, the scene in her classroom is typical of the children she teaches.   Gallegos teaches high school Spanish.  She became part of their lives and families for three years.  She is willing to help her children succeed. After a couple of years,  Gallegos'  class becomes like home. Gallegos' Spanish class is taught mostly in English in sixth grade. By the time the students are eighth-graders, they are speaking fewer words of English and more of Spanish during the 50-minute classes.

"My goal is to get my kids to say something in Spanish every day." she said. "I want them to be able to talk to me. That's why I help them.  I praise them.  I recognize them when they do good work. And we have fun. The day I stop having fun is the day I am going to consider a different job. "

If a student needs help, Gallegos offers the student a "lifesaver", which is help from a classmate. The lifesaver gets a piece of candy as a reward.  As the students said. "Gallegos' class is anything but boring." It is because of Gallegos'  efforts and determination that she is the teacher who they think is most deserving of one of Collier County's Golden Apple Awards.

"I don't teach a subject. I teach kids. This is what I was born to do." Gallegos said.

45.The scene in Gallegos' class is mentioned at the beginning of the passage to                 .

A. Her interesting class                    B. Her determination in study.

C. Rewarding her students with prizes.      D. Her efforts made to teach kids.

A. Spanish classes with fun                 B. Golden Apple Awards

C. This is what I was born to do            D. How to get along with kids

C

      As a young ice skater, I had flown pretty high, pretty quickly.  My partner and I won the Canadian junior pairs championship when I was 14. Later I was thrilled to  be  picked  to  skate  in  the  1994  Olympics  in lillehammer, Norway. But then everything came crashing down.

      We finished 12th at the Games.  I soon quit doubles skating and tried to continue in singles. But I wasn't good enough;  I didn't even compete in the next two national championships.  I felt like I was a somebody who had become  a nobody.

      I was 18 and had just graduated from high school, when my mum told me, "You can't just depend on skating to make a living. You' d better find a job." I knew she was right. So I found a job at a restaurant where I waited tables and did anything else that needed to be done.   In fact,  I worked so hard that I had never got the chance to have a break. No one cared that I had been an Olympic skater; I was judged only by how hard I worked.

      That job taught me so many things.  I learned,  for example, how to deal with people. As an athlete, this was new to me.  One day a man loudly called me over to his table and complained,    "This milk is sour.  I am not drinking this junk!  I want my money back! "  It was near the end of my shift (班) and I wanted to tell him how rude I thought he was. But I had learned that "the customer is always right" and a smile can go a long way. "I'm really sorry,  sir.  I'll get you a free cup."  I said with a smile. When I brought him his coffee, his attitude changed. And he left me a tip!

      My first job taught me that it is important to do your best at anything you try.  I knew nothing about being a waitress when 1 started my job but by the time I left when 1 decided to return to skating -- I had earned a raise and my boss's praise. They meant so much to me.

49.How did the author feel after she picked up singles skating?

A. Thrilled.                         B. Confident.

C. Disappointed.                     D. Proud.

50.What did the author do about the man's complaint?

A. She told him how rude he was.     B. She gave his money back.

C. She asked her boss for help.      D. She apologized with a smile.

51.We can learn from the passage that       .

A. the author did very well at the 1994 Olympics

B. the author was successful as a young ice skater

C. the author didn't follow her mother's advice

D. the author gave up her skating career

52.The passage is mainly about            .

A. the author's skating life            B. a lesson from skating

C. the author's first job               D. how to be a good waitress

    In the past I found myself under the impression that if I reached certain goals,  or succeeded in doing certain things then happiness would follow―in the short term I'll admit that it often did.

     The problem was that over time I realized that I wanted more-I wanted to feel joy on a more constant basis.   I didn't want it to be something I. had to continuously chase after. In other words I wanted a kind of happiness that didn't require me to achieve something in order to be happy.

    Fortunately I've come to the realization that for the most part I can choose to be happy on a daily basis.  In order to do this at times it may even mean faking it-better yet,  forcing the feelings Until the genuine happiness and gratefulness sets in.

    I've found that something as simple as smiling, can do wonders to help me see that I have in me the ability to choose to be happy.

     I'd strongly encourage you to take breaks during the day to think about those happy memories that you've collected in your life.

     Deciding to move forward and choosing happiness over sorrow is a tough choice. Sometimes you may feel as though you are fighting an uphill battle.  At other times it will seem that the dark clouds may never give way to the sunshine,  It is at those very moments that we have to remind ourselves that somewhere among whatever chaos (混亂)  may surround us -- we still have the choice to decide on happiness.

57. What would be the best title for the passage?

    A. Goals and happiness         B. Choose to be happy

    C. What is happiness           D. Success and happiness

58. In Paragraph 2, the author intends to           .

    A. describe his experience of achieving success

    B. tell that you can't be happy unless you succeed

    C. seek happiness on a more regular basis

    D.explain success doesn't mean true happiness

59. What does the underlined word "genuine" in Paragraph 3 probably mean?

    A. True.                                  B. Permanent.

    C. Simple.                                D. Unexpected.

60.The author suggests all of the following ways of creating feelings of happiness EXCEPT               .

    A. trying to be happy every day         B. actively choosing happiness

    C. setting goals that one can achieve    D. thinking about happy memories
