One day, a professor entered the classroom and asked his students to prepare for a surprise test. They waited anxiously at their desks for the test to begin. The professor  (1)  the question papers, with the text facing down as usual.  (2)  he handed them all out, he asked his students to  (3)  the page and begin. To everyone's surprise, there were no  (4)  , just a black dot in the center of the page. The professor, seeing the expression on everyone's face, told them the following:

“I want you to write what you  (5)  there. “

The students,   (6)  , got started on the inexplicable (费解的) task.

At the end of the class, the professor  (7)  all the answer papers and started reading each one of them aloud in front of all the students. All of them, with no  (8)  , described the black dot, trying to explain its position in the middle of the sheet, etc. etc. etc. After all had been  (9)  , the classroom silent, the professor began to explain:

“I'm not going to grade (打分)this. I  (10)  wanted to give you something to think about. No one wrote about the  (11)  part of the paper. Everyone focused on the black dot, and the same happens in our  (12)  . We have a white paper to observe and  (13)  , but we always focus on the dark spots. Our life is a  (14)  given to us with love and care, and we always have  (15)  to celebrate: nature renewing itself every day, our friends around us, the job that  (16)  our livelihood and the miracles we see every day.

  (17)  , we insist on focusing only on the dark spots: the health issues that bother us, the lack of money, the  (18)  relationship with colleagues, the  (19)  with a friend, and etc.

The dark spots are very  (20)  compared to everything we have in our lives, but they are the ones that pollute our minds. ”

Martin:Before 1945, hardly anyone outsideof New Mexico had ever heard ofAlamogordo,   (1)  was alonely town.

Daisy:Whatˈs the place like?

Martin:The land around it was sand-covereddesert and   (2)  (complete)empty. Because the weather wasalmost always clear and   (3)  (peace), a spot of desert nearAlamogordo   (4)   (choose)as the test site for the firstatomicbomb(原子弹).

Daisy:What I know is   (5)  _ on July16, 1945, the atomic bomb was set off.

Martin:Yes. But for several weeks, the testwas kept secret. With an atomicbomb   (6)   (drop) from anAmerican plane on Hiroshima, Japanon August 6, 1945, newspapers andradio stations all over America toldof the test of the bomb in NewMexico. Almost everybody wassurprised  (7)  (learn) wherethe bomb had been made and tested;the deserts of the Southwest hadhidden the secret well.

Daisy:You mean nobodywitnessed(目击) thescene when the bomb was tested?

Martin:No. Observers said they saw something  (8)   (like) anythingthey had seen before. It was a hugeand colorful fireball more brilliantthan the sun,   (9)  (flash) asit rose for miles into the air. Nonationin the world had ever possessed sucha weapon   (10)   terrible anddestructive as theatomic bomb.

  Many people believe that dogs should not be kept in large cities. They say that pet dogs should be banned because they are dangerous to man since they carry diseases and that they attack people especially young children.   (1)   For example, they eat large quantities of food that could go to feed the poor and the starving of the world. What's more, many people spend large amounts of money on their dogs, even buying them beds and toys,taking them to doctors when they are sick, burying them in pet cemeteries when they die.   (2)  

    However I disagree with these arguments. Many animals carry diseases not just dogs. In fact people carry more dangerous diseases than dogs.   (3)   And if they are it is because they have attacked or frightened the dog. As for money spent on dogs, what people do with their money is their own business. Finally there will always be the poor in the world.

  Let us now look at why dogs are good animals.   (4)   They can also help the police to search for drugs and explosives (炸药). In addition, dogs are able to save people's lives after an earthquake when they are buried under fallen buildings. What's more, dogs are used to protect property (财产) as well as women and children.   (5)  

   For all these reasons I believe that pet dogs should not be banned from cities.

My grandfather was probably the toughest man I've ever known.   31  , as a child I didn't realize it. To me, he was just a(n)   32   grandfather. But his   33   changed the way I thought about him and it is the event that has had the most   34   effect on me in my life.

He died on Thanksgiving Day. At his funeral, his brothers began to   35   stories about their lives. They recalled their childhood, when they were poor and   36   in the countryside, their hunting adventures in the woods and their happy family get-togethers   37   festivals. In their eyes, my grandfather was understanding and kind-hearted. He was always there,   38     happiness to the family. They drank and continued telling stories, and then I noticed the   39  ; not polite smiles, but loud laughter.

  40   laughed. The louder their laughter was, the more   41   I felt. I pulled my mother aside.

“Grandfather is dead. How can they laugh?” I said in   42  . 

“What is the most important thing you   43   about your grandfather?” my mother asked. “ He wouldn't want us to be   44  . That's not how he would want to be remembered. He would have wanted   45   this kind of party.”

I   46  . Out of all the things I remember about him, the most   47   thing is his laughter. He   48   all the ups and downs in his life. No matter how hard something was in his life, he always   49   it with laughter.

I don’t know what   50   looks like, but I believe it is filled with his laughter.

Last weekend I went snowshoeing with a group of teachers from my school.   (1)  , it felt a little strange --- a bit like ,wearing flippers（脚蹼）  (2)   you swim! I felt quite clumsy to start with, and it was   (3)   to climb over the fallen trees with the snowshoes   (4)   to my feet. However, I love   (5)   and am used to walking in mountainous areas   (6)   I soon got used to it. I loved walking through the forest and seeing all the trees covered in   (7)  ! At times, walking uphill in the snow was hard,   (8)   when there were rocks underneath the snow. Once we reached the   (9)   it was worth it! The mountain we   (10)   was called "Le Tanet" and it was l,292 mhigh --- thatˈs higher than Snowdon, the tallest mountain in Wales! The sky was a bit gray, but the views were   (11)  . I managed to get some great   (12)   --- and remembered to use my new camera! After taking lots of photos, we started going down. In some ways, going down the mountain was harder than   (13)  . It was very steep(陡峭), and it was easy to     (14)   inthe snow.

    At the bottom, we had a hot drink in a cabin --- it was clearly   (14)   after a few hours of walking in the cold! Before we went   (15)   I attempted sledging(雪橇) which Iˈd never   (16)  before! It was great fun!

    To be honest, Iˈd really   (17)   snowshoes as an alternative to the more well-known   (18)   sports. Besides being a lot cheaper than skiing, itˈs easier to do and is considered to be a lot   (19)  !

       A blind boy sat at a street corner with a hat by his feet. He held up a sign which said, "I am blind. Please    (1)    ."

      There were only a few coins in the  (2)    . A man was walking by. He dropped a few coins into the hat. Then he took the sign and wrote some words on it. He put the sign back   (3)      .everyone who walked by would see the new words.

         Soon the hat began to fill up. A lot more people were giving  (4)  to the blind boy. That afternoon the man came to see how things were. The boy recognized his   (5)     and asked, "Were you the one who   (6)   my sign this morning? What did you write?"

       The man said, "I only said what you said but in a  (7)    way." What he had written was: "Today is a beautiful day and I cannot see it." Both signs told people the boy was  (8)   . But the first sign simply told people to help. The second sign told people that they were able to enjoy the  (9)   of the day, but the boy could not enjoy it because he was blind.

        There are at least two   (10)    we can learn from this story. First, be thankful for what you have. Someone else has less. Help when you can. Second, be creative. Think differently. There is always a better way!

A Very Special Special Olympian

The professor was searching for student volunteers in the lecture room for a Special Olympics event. As the sign-up sheet went up and down the rows, I started to come up with my  (1)  . Maybe it was the distance to the college where the event was to take place, or the early hour that   (2)   had to report for duty. Whatever the reasons that made me hesitate, I am thankful to this day that I   (3)   up volunteering. If I had missed the event, I would have missed one of the most unforgettable moments that I have ever   (4)  .

   I arrived at the volunteer tent bright and early. My task was   (5)  . I was to stand at the finish line only and wait until the event was over and then take the   (6)   to the announcing booth(公告处). Standing at the finish line, I was able to witness many amazing efforts and close races. I was most impressed by the effort each athlete put into his or her   (7)  . What also impressed me was the sincere   (8)   each athlete expressed while participating though sometimes the joy of participating in a sporting event can get   (9)  inthe fierce competition of winning and losing.

Then an amazing moment happened right before my eyes. A group of athletes were   (10)   up to run a short race. One of them was in a wheelchair, a little girl with a   (11)   smile, wearing bright bows in her hair. Her smile filled the stadium that day. I couldn’t help but smile back at her.

   The gun sounded. They were off. Runners sped upinthe   (12)   with all their might. My eye  (13)   for the little girl with the bright bows. There she was, pumping her arms with all the   (14)   she had. Her efforts were getting little result, but that did not stop her. I noticed as she got closer that she also had an injured arm. But that did not stop this bright star. The race was long over   (15)   the young athlete kept pumping her arms. As she finally   (16)   the finish line, the noise of the crowd was thunderous. There I stood  (17)  , with tears falling down my cheeks.

After all these years, I can still hear those cheers. I wish I could thank that remarkable athlete for what her efforts   (18)   this unmotivated college guy. I grew up a lot that day because of the   (19)   of that little girl in the wheelchair. I was   (20)   that day of a poem from a book that states, “Whatever you do, do it with all your might.”
