She seemed so sad. I looked at her, trying to  44  some words to say. I asked her if she had forgiven  45  for not realizing her father’s dream. She answered that she couldn’t forgive herself  and felt so  46 .Slowly, I began to tell her about forgiveness. I encouraged her to  47  that because I believed her father wanted that too. She should forgive herself  48  how awful she thought she had been.
I told her about  49  I had done as a teenager for which I had felt guilty for many years. How I was  50  with the choice of forgiving myself or to  51  feeling guilty for the rest of my life. I had  52  to forgive myself . The light in her eyes went on. She began to understand that she was  53   forgiven and could forgive herself. She could be  54  and happy.

William Shakespeare is the most famous playwright (劇作家). Although he died in 1616, people still go to see his plays. Among the most popular are Ｒｏｍｅｏ ａｎｄ Ｊｕｌｉｅｔ, Ａ Ｍｉｄｓｕｍｍｅｒ Ｎｉｇｈｔ’ｓ Ｄｒｅａｍ and Ｈａｍｌｅｔ — the story of a prince who struggles to respond to the crimes around him.
Shakespeare, who was born in 1564, was an actor as well as a writer. Most of his ideas for plays were taken from history, people’s conversation, ancient stories, and also from other writers. He wrote not only about kings and queens and princes, but also about friends and ordinary people. He wrote about the cruelty of war and the bravery of heroes, as well as about jealousy, joy, hate, ambition and love. His stories live on. The tragedy Ｒｏｍｅｏ ａｎｄ Ｊｕｌｉｅｔ was reborn as the musical Ｗｅｓｔ Ｓｉｄｅ Ｓｔｏｒｙ and more recently as the movie Ｒｏｍｅｏ ａｎｄ Ｊｕｌｉｅｔ with the wonderful performance of Leonardo DiCaprio and Claire Danes.
He invented a number of great characters: powerful magicians, thrilling witches, smart women and both wise and wicked men. He also invented some great phrases. If you’ve ever said, “Oh, for goodness sake!” you can thank Shakespeare for that. “To be, or not to be: that is the question,” Hamlet says. “Good night, good night. Parting is such sweet sorrow, that I shall say good night till it is morrow,” says Juliet to her Romeo.
Don’t be surprised if you don’t understand everything when reading Shakespeare or watching one of his plays because the meanings of many words have changed over the years. And Shakespeare’s characters speak in poetry, so their speeches can be complicated.
It does help to find out a little bit about the story before reading a Shakespeare play. It’s worth the effort. As Shakespeare wrote, “All the world is a stage.” And in his plays you’ll find that an entire world is waiting for you.
小題1:Shakespeare created the following characters EXCEPT ________.

A．Juliet

B．Hamlet

C．Claire Danes

D．Romeo

小題2:From Paragraph 3 we can learn that ________.

A．most of the characters created by Shakespeare were negative ones

B．most of the phrases used today were invented by Shakespeare

C．“Oh, for goodness sake!” is what Juliet says to Romeo

D．Shakespeare contributed greatly to the development of English

小題3:Which of the following is a reason why it’s difficult to understand some of Shakespeare’s plays?

A．There are many new words in his plays.

B．He wrote his plays using uncommon words.

C．The characters in his plays speak in poetry.

D．Most of the words in his plays are outdated.

小題4:We can infer from the passage that ______.

A．most of Shakespeare’s plays have been made into films

B．language changes with the development of society

C．Shakespeare made lots of money from his works

There are a number of special days of the year that are celebrated in different countries. The origins of most of the days are unknown. They were certainly not created by individual people. Other days, however, especially those celebrated in western countries, often owe their origins to a particular person. One of the most popular of these, even though it is fairly recent, is Mother’s Day. Mothers have always been highly regarded in all cultures. The ancient Romans had a festival known as Hilaria, during which children took presents to the temple of the “Mother of the Gods”. The Christian Church adopted this idea and called it Mothering Sunday. However, over the years this custom was gradually forgotten and almost disappeared by the end of the 19th century.
Born in 1864 in Virginia, USA, Anna Jarvis was a school teacher and believed children should show gratitude to their mothers for all their love and care. Encouraged by a friend, she wrote to thousands of important people—politicians, churchmen, doctors, city officials—and asked them to support her idea: a special day of the year for thanking mothers.
In 1910 the Governor of West Virginia introduced Mother’s Day into the state. The date chosen was May 10—the second Sunday in May, which is still observed in America today. This date was chosen because May 10 was the date on which in 1908 Anna Jarvis’s mother had died. In 1914 President Woodrow Wilson made May 10 the official date for Mother’s Day throughout the United States.
Soon there was a Mother’s Day International Association and the custom began to be adopted in many countries of the world.
Anna Jarvis, a sad and disillusioned（失望的） woman, died in 1948. The custom she had worked so hard to establish and which had become almost universal had lost its original purpose. It had been taken over by business. Like Christmas, the giving of presents and the sending of cards had become a multi-million-dollar industry.
小題1:The story is about     .

B．the origin of a special day for mothers

C．President Wilson and Anna Jarvis

D．how people celebrate Mothers Day

小題2:Anna Jarvis wanted to       .

A．May is in the American spring

B．it was the second Sunday in May in 1910

C．President Wilson liked the date

D．this was the date on which Anna Jarvis’s mother died

小題4:Unfortunately, Anna Jarvis was not happy with Mother’s Day when she died because     .

A．her mother was not there to see it

B．she had never been a mother herself

C．people were too interested in making it a business

D．no one gave any presents or cards to their mothers

To Whom It May Concern:
On March 5, 2012 , I bought a Perfect Muffin Kit(松餅粉 ) from your store at Midfield Shopping Center. The cashier who assisted me was George. George was very friendly and told me that the Perfect Muffin Kit would live up to the guarantee on the box: “Perfect Muffins Every Time!”.
Unfortunately, this product did not live up to what it promised . The muffins I made were far from perfect . I followed the directions in the package very carefully . First , I removed the bag of mix from the box. Then , I poured it into a bowl. Next, I added the correct amount of water to the mix and stirred it. According to the directions, after stirring the mixture , I added half a cup of dried prapes, nuts , berries, or another favorite ingredient(配料 ) . My favorite ingredient happens to be hot sauce (沙司 ). I find that a bit of hot sauce makes pizza and soup taste very delicious. So, continuing to follow the directions, I added half a cup of hot sauce to the mix and stirred it. Finally, I poured the mix into muffin tins and baked it in the baker at 350 degrees for exactly 20 minutes.
When the muffins finished baking, I was very excited to eat the “Perfect Muffins” as promised on the box. You can imagine my disappointment when, upon tasting the muffins, I discovered that they were not perfect. These muffins were , in fact , absolutely terrible. Not even my dog was interested in eating these supposedly “perfect”muffins.
I would appreciate a full refund(退款 ) of $3.99 for this product as soon as possible. Enclosed are the receipt, the empty box, and one of the un-perfect muffins so that you can experience it for yourself . Thank you for your attention to this matter.
Sincerely ,
Michelle Bauer

Grandfather was an elder Cherokee Native American who had a wrinkled, nut brown face and kind dark eyes．His grandson often came in the evening to sit on his knee and asked the many questions that children asked．
One day the grandson came to his grandfather with a look of anger on his face and the following story．"Father and I went to the store today and because I helped him, he bought me a present, a jack-knife．I went outside to wait for father and to admire my new knife in the sunlight．Some town boys came by and saw me．They surrounded me and started saying bad things．They called me dirty and stupid and said that I should not have such a fine knife．The largest of these boys pushed me back and I fell over one of the other boys．I dropped my knife and one of them picked it up and they all ran away laughing．I hate them．I hate them all．”
The elder Cherokee, with eyes that had seen too much, lifted his grandson's face so his eyes looked into the boy's face．Grandfather said, " Let me tell you a story．I, too, at times, have felt a great hate for those who have taken so much with no sorrow for what they do．But hate wears you down and does not hurt your enemy．It is like drinking poison and wishing your enemy would die．I have struggled with these feelings many times．It is as if two wolves are inside me．．．It is a terrible fight．
One wolf is good and does no harm．He lives in harmony with all around him and does not take offense (冒犯) when no offense is intended．It will only fight when it is right to do so and in the right way．This wolf stands for joy, peace, love, hope, sharing, modesty, kindness, friendship, sympathy, generosity, truth and faith．
The other wolf is full of anger．The smallest thing will set off his fiercest temper．He fights everyone, all the time, for no reason．He cannot think because his anger and hate are so much．
It is helpless anger, for his anger will change nothing．This wolf represents fear, envy, greed, self-pity, guilt, lies, false pride and superiority．
Sometimes, it is hard to live with these two wolves inside me for both of them try to control my mind．This same fight is going on inside you and inside every other person too．"
The boy looked into his grandfather's eyes and asked, "Which wolf will win?" The old Cherokee simply replied ．．．
"The one you feed．"

A farmer had some puppies（小狗）to   36  . He painted a sign advertising the puppies and   37__  nailing （釘）it to a post on the edge of his yard. As he was driving the last nail into the post, a little boy came to him.
“Mister,” he said, “I want to buy one of your puppies.”
“Well,” said the farmer, as he   38  the sweat off his face, “these puppies come from fine parents and cost   39  money. Do you have enough money?”
The boy    40   his head for a moment. Then reaching into his pocket, he pulled out a handful of   41  and held it up to the farmer. “I’ve got thirty-nine cents.

“I want that one,” the little boy said,   49   to the smallest one. The farmer said, “Son, you don’t want that puppy. He will never be able to run and play with you   50  these other dogs would.”
With that the little boy   51  back from the fence, and began    52    up one leg of his trousers.

In 2003, Bethany Hamilton,13, lost her left arm to a shark attack while surfing off Kauai, Hawaii. A new film ,Soul Surfer, is based on the story of how she overcame that to achieve her dream of becoming a professional athlete.
Growing up on the “garden isle” of Kauai, Hamilton spent every minute she could riding the waves. She was on the verge of (即將) becoming a top competitor in professional surfing. But while she was practicing at an isolated cove (小灣)，a four-meter-long tiger shark ripped off her left arm. Though her life was saved, nobody could imagine she would ever get back on a surfboard again.
In a true test of her faith and by tremendous will power, Bethany did get back up on a surfboard only a month after the attack. Six months later, she was competing again. Bethany Hamilton won her first amateur surfing championship just two years after she lost her arm. She also established the “Friends of Bethany,” a non---profit foundation dedicated to supporting sharks attack victims.
It’s a story told in her autobiography, which is the basis for the film that stars teenager Anna Sophia Robb. “I knew Bethany’s story, of course, but I thought ‘What an incredible role’ ,”explains Robb. “I was so fascinated by all of the challenges. What would it be like to have your arm taken and what would go through your head and how would your faith be challenged?”
The filmmakers used special effects to digitally remove Robb’ s arm .However ,no tricks were necessary for the surfing scenes because Hamilton herself did the breathtaking wave riding.
Now 21, Hamilton says she hopes audiences find inspiration in the description of the sport she loves.
“Not a lot of people know that much about surfing, so I hope they’re educated about it,” Hamilton says. “And most of all if people are going through a hard time, they could be encouraged and find inspiration to push through those hard times and see that, in my case ,so much good has come out of it.”

His name was Fleming, and he was a poor Scottish farmer. One day, while trying to eke（補充） out a living for his family, he heard a cry for help coming from a nearby bog (沼澤地). He dropped his tools and ran to the bog. There, mired（陷于泥坑）to his waist in black muck（淤泥） was a terrified boy, screaming and struggling to free himself.
