---I knew she was in because I heard her radio, but she didn't open the door for me .

---She ________ the bell.


  1. A.
    may not hear
  2. B.
    mustn't have heard
  3. C.
    may not have heard
  4. D.
    mustn't hear
C
考查否定推測的用法。
從題干中所提供的時態(tài)看這是一個對過去去發(fā)生的事情的推測。對過發(fā)生的事情的推測把握較大時用must + have +過去分詞。由此我們首先排除A．D兩項。但是must在用于推測時只能用于肯定形式，其否定形式必須用can't。
說明：表示推測疑問句要用can/could如：
Could the bank have made a mistake?
銀行會不會出差錯呢？
Where could he have gone on such a night?
在這樣一個晚上他能到哪里去呢？
We couldn't have heard them because of the noise from the river.
由于江水的響聲，我們不可能聽到那聲音。

He’s an old cobbler  (修鞋匠)  with a shop in the Marais, a historic area in Paris. When I took him my shoes, he at first told me: “I haven't time. Take them to the other fellow on the main street;
he'll fix them for you right away.
But I’d had my eye on his shop for a long time. Just looking at his bench loaded with tools and pieces of leather, I knew he was a skilled craftsman (手藝人). “No,” I replied, “the other fellow can’t do it well. ”
“The other fellow” was one of those shopkeepers who fix shoes and make keys “while-U-wait” — without knowing much about mending shoes or making keys. They work carelessly, and when they have finished sewing back a sandal strap (鞋帶) you might as well just throw away the pair.
My man saw I wouldn't give in, and he smiled. He wiped his hands on his blue apron (圍裙), looked at my shoes, had me write my name on one shoe with a piece of chalk and said,“Come back in a week. ”
I was about to leave when he took a pair of soft leather boots off a shelf.
“See what I can do?” he said with pride. “Only three of us in Paris can do this kind of work. ”
When I got back out into the street, the world seemed brand-new to me. He was something out of an ancient legend, this old craftsman with his way of speaking familiarly, his very strange, dusty felt hat, his funny accent from who-knows-where and, above all, his pride in his craft.
These are times when nothing is important but the bottom line, when you can do things any old way as long as it “pays”, when, in short, people look on work as a path to ever-increasing consumption (消費) rather than a way to realize their own abilities. In such a period it is a rare comfort to find a cobbler who gets his greatest satisfaction from pride in a job well done.
68. Which of the following is true about the old cobbler?
A. He was equipped with the best repairing tools.
B. He was the only cobbler in the Marais.
C. He was proud of his skills.
D. He was a native Parisian.
69. The sentence “He was something out of an ancient legend. ” (paragraph 7) implies that _______.
A. nowadays you can hardly find anyone like him
B. it was difficult to communicate with this man
C. the man was very strange
D. the man was too old
70. According to the author, many people work just to _______.
A. realize their abilities                          B. gain happiness
C. make money                                         D. gain respect
71. This story wants to tell us that_______.
A. craftsmen make a lot of money           B. whatever you do, do it well
C. craftsmen need self-respect                     D. people are born equal

I was shopping in the supermarket when I heard a young voice.
“Mom, come here! There’s this lady here my size!”
The mother rushed to her son; then she turned to me to apologize.
I smiled and told her, “It’s okay.” Then I talked to the boy, “Hi, I’m Darryl Kramer. How are you?”
He studied me from head to toe, and asked, “Are you a little mommy?”
“Yes, I have a son,” I answered.
“Why are you so little?” he asked.
“It’s the way I was born,” I said. “Some people are little. Some are tall. I’m just not going to grow any bigger.” After I answered his other questions, I shook the boy’s hand, and left.
My life as a little person is filled with stories like that. I enjoy talking to children and explaining why I look different from their parents.
It takes only one glance to see my uniqueness. I stand three feet nine inches tall. I was born an achondroplasia dwarf. Despite this, I did all the things other kids did when I was growing up.
I didn’t realize how short I was until I started school. Some kids picked on me, calling me names. Then I knew. I began to hate the first day of school each year. New students would always stare at me as I struggled to climb the school bus stairs.
But I learned to smile and accept the fact that I was going to be noticed my whole life. I decided to make my uniqueness an advantage rather than a disadvantage. What I lacked in height, I made up for in personality.
I’m 47 now, and the stares have not diminished as I’ve grown older. People are amazed when they see me driving. I try to keep a good attitude. When people are rude, I remind myself, “Look what else I have — a great family, nice friends.”
It’s the children’s questions that make my life special. I enjoy answering their questions. My hope is that I will encourage them to accept their peers (a person of the same age, class, position, etc.), whatever size and shape they come in, and treat them with respect.
【小題1】.. Why did the mother apologize to the author?

A．Because the boy ran into the author.
B．Because the boy laughed at the author.

【小題2】. When did the author realize that she was too short?
A．When she began to go to school.B．When she was 47 years old.
C．When she grew up.D．When she met the boy in the supermarket.
【小題3】. Which of the following word can best replace the underlined word “diminished”?
A．dismissedB．increasedC．decreasedD．discriminated
【小題4】. How does the author feel about people’s stares?
A．Angry.B．Calm.C．Painful.D．Discouraged.

When people hear that I’m the youngest person to row solo across the Atlantic Ocean, they all have the same question: How did a 22-year old woman row a 19-foot boat for 70 days through high winds and crashing waves? Well, the biggest  difficulty for me wasn’t physical. By the time I decided to do the ocean row, I had already biked 3,300 miles cross-country, run across the Mojave Desert, and swum the 325-mile length of the Allegheny River. No, the tough part would be mental: How would I handle the loneliness, the boredom of the vast sea?
I set off on January 3, 2010. I set my sights on getting past the quarter-way mark, which would take about 20 days.
Day 20, January 22, was gray and cloudy. I could have done something to celebrate, such as treating myself to a chocolate bar. But I didn’t.
I was suffering from terrible loneliness. I hadn’t seen landing over two weeks. Every day was beginning to feel the same. Eating, rowing, sleeping, watch the sky, watch the ocean.
Then, around sunset, I saw something move on the horizon. They were dolphins! They circled my boat. Suddenly I felt so grateful. They had come to help me celebrate, just when I needed them. I rowed at full strength for the next 20 minutes with the dolphins around. By the time we went our separate ways, I was no longer lonely. Better yet, I knew I would be okay.
I did make it, all 2,817 miles. I hit the coast of Guyana, South America, on March 14, after 70 days and five hours at sea. My ocean row raised $70,000 for the Blue Planet Run Foundation, which funds drinking water programs around the world. I know some athletes spend the entire journey imagining the end, and that helps them get through. But for me, the secret is to focus on the moment, where you experience the personal growth—those moments of awareness of being connected to the sun, the weather, and the waves. And, on the best day of my life, those dolphins, which freed myself from terrible loneliness.
【小題1】
Which is the step taken as part of preparation for the tough row?

A．swimming the 325-mile length of the river
B．a(chǎn)nswering the same question raised by people
C．running 3,300 miles cross-country
D．biking across the Mojave Desert
【小題2】
What does the underlined part mean?
A．I didn’t have any chocolate bar for energy.
B．I wasn’t in the mood to celebrate my first goal.
C．It’s a pity not to celebrate my passing the quarter of the way
D．It’s a pity not to treat myself to a chocolate bar on Day 20.
【小題3】
What can be implied from the last two paragraphs?
A．Imagination was an effective way to help me get through.
B．The Blue Planet Run Foundation helped me a lot.
C．The dolphins accompanied me to reach my destination
D．The unexpected dolphins swept away my loneliness
【小題4】
Which can be the best title of the passage?
A．The day I stopped being lonely
B．The only challenge for a 22-year old
C．How to overcome loneliness at sea.
D．How to row alone across the Atlantic

What makes a gift special? Is it the price you see on the gift receipt? Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?
This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming. and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.
I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreaming, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood. I felt that this was a gift that my father would truly appreciate.
Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.
【小題1】The idea for a special gift began to form when the author was______.

A．doing shoppingB．having a debate

【小題3】The underlined word "it" in Paragraph 3 refers to a poem by_____.
A．the father B．the author
C．William BlakeD．Edgar Allan Poe
【小題4】The author made the gift by_____.
A．searching for the poems online
B．drawing the background by hand
C．painting the letters in three colors
D．matching the words with pictures
