“Hey, how are you doing I'm Courtney. What grade are you in What's your favorite book Elephant and Piggy Yeah, I got it.”
If you thought you'd walked into a library with a greeting like that, you wouldn't be too far off. In fact, you've entered the workplace of Courtney Holmes, the Storybook Barber.
Two years ago, Dubuque, Iowa, held its first yearly Back to School Bash, offering needy families an opportunity to learn about free resources in the community (社区). Holmes agreed to participate. Saturday was his busiest haircutting day, but he chose to donate his time and give free haircuts to underprivileged kids so they'd look sharp on that first day of classes. But then he had a lightbulb moment (突然醒悟的一瞬): “The kids should earn their free haircut by having to read a book to me,” Holmes said.
The idea was so popular that he continued it for the next two years. Five- to ten-year-old boys would grab a favorite book, settle into the barber chair, and read aloud while Holmes cut their hair. If they stuttered (结结巴巴地说) over a word, Holmes was there to help.
After the haircut, they'd review the book, from the characters and vocabulary to the themes — just like in school, only more fun.
Holmes admits he, too, benefits from the free snip-and-reads.
“There was this seven-year-old Bob, who struggled through his book, stuttering over words even though he didn't have a stutter,” said Holmes. He had the boy take the book home and practice. When the child came back a few days later, “He read it with no problems. That inspires (鼓舞) me.”
Holmes and his family have recently moved from Dubuque to a Chicago suburb. When they get settled, he plans to continue his role as the Storybook Barber. “The way the world is today with guns and violence,” he says, “it's a safe haven (避风港) for the kids, to come to the barbershop and read books.”
24. What does the underlined word “underprivileged” in Paragraph 3 mean
A. Unruly.
B. Poor.
C. Intelligent.
D. Unusual.
25. What did Holmes say about Bob
A. He fired his enthusiasm.
B. He gifted him a new book.
C. He preferred to read alone.
D. He had a language disability.
26. What can we infer about Holmes from the last paragraph
A. He showed great concern for kids.
B. He faced serious money problems.
C. He had an excellent sense of humor.
D. He built a shelter for homeless kids.
27. What is the best title for the text
A. Great minds inspire great deeds
B. A new way to make reading fun
C. An unusual library in Dubuque, Iowa
D. Barber gets kids reading with free haircuts
C
Ragtime is a fast and complex kind of music that was popular around the beginning of the twentieth century. Scott Joplin is now considered to be the most important American ragtime composer and piano player. During his lifetime, Joplin only enjoyed a brief period of professional success in the early 1900s. However, his work had an important, lasting effect on audiences, as well as other composers.
When ragtime first appeared in the late nineteenth century, it was considered a low form of cheap entertainment, not a serious musical movement. Then in 1899, Joplin wrote a ragtime song called Maple Leaf Rag. The song showed Joplin's creative blend (融合) of African-American rhythm (节奏) and more established European-American musical styles. It was a huge success and helped to make ragtime popular with the general public. Maple Leaf Rag was the first instrumental composition to sell over one million copies of sheet music. It was also the first music by an African American to find a large audience among European Americans.
Although the general ragtime style already existed before Joplin began composing, his work attracted a lot of attention from other ragtime composers of his time. Songs likeMaple Leaf Rag influenced these composers mostly because they were very popular with the public. And many of them started to add similar fast and complex rhythm to their music. Later, composers came to appreciate the high quality of Joplin's music, which has continued to capture (引起) the imagination of many composers and musicians up to the present day. For example, many later jazz musicians were influenced by Joplin's complex African-style rhythm. Jazz, in turn, went on to influence many more popular music styles. These include the blues, rock and roll, soul, and even hip-hop. As a result, many music historians now list Joplin's work as an early basis of all modern popular music.
28. What do we learn about ragtime
A. It originated in Europe.
B. It was started by Joplin.
C. It disappeared around the year 1900.
D. It was most popular during Joplin's time.
29. Which of the following is TRUE regarding Maple Leaf Rag
A. It was not serious music.
B. It made ragtime cheaper.
C. It was a mix of musical styles.
D. It failed to entertain audiences.
30. How did other composers feel about Joplin's music
A. It was top-class.
B. It was hard to play.
C. It was slow and soft.
D. It lacked imagination.
31. What's the focus of this text
A. The life story of Joplin.
B. The rise of ragtime composers.
C. The development of jazz music.
D. The influence of Joplin's music.

The term “laughing stock” refers to a person, thing or situation that is ridiculed. Although the exact origin of this term is unknown, it's believed to have been derived from (起源于) the stocks in which criminals were placed to be subjected to public ridicule.
During the time this phrase was first seen in print, one of the preferred methods of punishment for less serious crime was putting individuals in stocks. Stocks were wooden structures that would hold a person immobile for long periods of time, usually by securing the person's head and hands in the holes cut between two boards that were mounted on a pole. The physical aspect of being held in stocks caused pain, and they were commonly placed in public areas so passers-by could ridicule those who were being punished. It was common for people who were in stocks to be hit with mud, rotten foods and even animal excrement (粪便) that was thrown by the passers-by. This could have led to the use of“laughing stock” in old English sayings.
Another theory behind the phrase is a more literal interpretation (字面解释). The word “stock” can mean a block of wood that provides support. A stock also can be the butt end (根端) of a structure or tool, such as a gun. When a person or an action becomes the base of a joke, it can be said they are the butt of the joke, or the “laughing stock.”
The term is often used in modern times. If an idea can be laughed at, the idea can be the “laughing stock”. This term is seen in print media and heard on radio and television, and it has found a way into most dictionaries and other reference books that list common expressions.
Although the term might be derived from the public humiliation (羞辱) of actual criminals, the act of putting people in stocks is sometimes done in modern times for fun and public benefit. For example, at some fundraising events or carnivals, a volunteer or willing worker might be placed in stocks, and other people can pay for the special right of throwing water balloons, cream pies or other soft, wet things at the face of the person in the stocks. This is done to raise money and draw laughter, making the person in the stocks a true “laughing stock”.
32. In old times, stocks were used .
A. to attract passers-by
B. to punish criminals
C. in public ceremonies
D. for entertainment purposes
33. If we say a person is a “laughing stock”, he is .
A. silly
B. strange
C. guilty
D. careless
34. What do we learn about the term “laughing stock” in Paragraph 4
A. It developed very fast.
B. It refers to a funny idea.
C. It is widely used and accepted.
D. It has different meanings now.
35. What is the aim of putting people in stocks in modern times
A. To humiliate them.
B. To enrich people's experiences.
C. To explain what a laughing stock is.
D. To collect money and bring pleasure.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Music

Music is a group of sounds that people have arranged in a pleasing or meaningful way. All cultures of the world make some forms of music. Music can be simple — for example, one person tapping (轻敲) out a beat on a log drum or singing a children's song. 36
All music includes basic elements, or parts. The main elements of music are rhythm, melody, harmony, and form.
37 The most important part of rhythm is the beat. When you tap your foot to a song you like, you are tapping out the beat. The speed of the beats is called the tempo (速度). The pattern of the beats is called the meter (节拍).
Melody is a series of different tones, or sounds, in a piece of music. The tones are played one after another to make up a song. 38 The highness or lowness of a tone is called its pitch (音高). Musicians describe different tones with the letters A, B, C, D, E, F and G.
Harmony takes place when people play more than one tone at the same time. Groups of tones played together are called chords (和弦). 39
Form is the way people put rhythm, melody, and harmony together. 40 Repeating a short melody is one of the simplest forms. For example, in the song Mary Had a Little Lamb, each verse repeats the same melody. A symphony is a more complex form. In a symphony, different groups of instruments may play different melodies at the same time or a series of harmonies.A. The tones in a melody may be low or high.
B. Rhythm describes the length of musical sounds.
C. There are many different types of musical forms.
D. The tempo may be fast or slow at different points.
E. Harmony also describes the way chords go along with a melody.
F. Drums help other instruments and voices keep the rhythm in many songs.
G. Music can also be complex — for example, hundreds of instruments playing together for hours.

Dear Charlie,
I am so gladly to hear that you are learning Chinese culture in the Confucius Institute.
Mencius' Mother Moving Three Times tells about how Mencius' mother moves again and again to provide his son with a good study environment. She did such because Mencius was influenced by the people in the neighborhood so much. Final, they came to a place near a school. Mencius' mother was satisfying as the people living there were well educated. The story shows that environment is very important for a kid's study. But nowadays, people value it a lot.

书面表达
One possible version:
Music or noise
In my opinion, the activity should be limited.
As we all know, music plays an important role in our lives. Music can produce a lively and happy atmosphere, which can help reduce our tiredness and bring us relaxation after hard work and study. What's more, listening to music can improve our health.
However, as the saying goes, every coin has two sides. Music at the wrong place or time may be noise to others, especially if it is loud. If your music becomes others' noise, it can destroy your relationship with your neighbors. Whatever we do, we should think about other people's feelings.
