But it is said that it began in the early 1900s. Jazz was a new kind of music, for America and the world, and New Orleans was its birthplace. Here are some information about jazz.Who were the jazz pioneers? Most were blacks. This music was not written down, and at first only blacks played it. It was hard for white musicians to learn the new style. But soon they, too, were playing jazz. The popularity of this music spread. From New Orleans, it traveled up the Mississippi to Chicago, then to Kansas City and New York. By the 1920s, there were many jazz musicians, both black and white. Many of them were famous. One man was better than the rest. His name was Louis Armstrong.Louis Armstrong was a born musician. He was not only talented but also hard-working. He also had a good sense of humor and a big, good-natured smile. These personal qualities were valuable in his rise to fame. After he became famous, he traveled around the world. It seemed that everyone wanted to hear Louis play. But life was not always easy, especially at the beginning.Louis Armstrong was bornin1900 in New Orleans. His father never went to school and his mother could hardly read. When Louis was still a kid, his parents separated, and Louis lived with his mother. How hard their life was can readily be imagined. And yet Louis smiled through everything. He later wrote, “My whole life has been happiness. Life was there for me and I accepted it. Whatever happened has been beautiful to me. I love everybody.”4．The underlined word “they” in Paragraph 2 refers to________.A．new styles B．jazz pioneersC．black musicians D．white musicians5．What made Louis Armstrong become the best jazz musician?A．His family background.B．His big, good-natured smiles.C．His talent and hard work.D．His good sense of humor.6．What is the passage mainly about?A．The development of jazz and its best musician.B．The development of music.C．The influence of Louis Armstrong.D．The influence of jazz on Americans.7．This passage maybe taken from ________.A．a science paper B．a music magazine C．an art picture D．a Chinese bookThe Chinese art of paper cutting has a long history. The earliest paper cutting was found in China in the Northern Dynasties. The United Nations Educational, Scientific and Cultural Organization ( UNESCO ) has recognized the art, called Jianzhi, on its Intangible (非物质的) Cultural Heritage (遗产) list. V oyo Woo, who is a Chinese student studying in the US, hopes to introduce the traditional Chinese art to Americans in her spare time.Ms. Woo loves paper cutting. And she works hard to celebrate the ancient art form. On a recent Saturday, Ms. Woo held a paper cutting show at a shopping center near Washington. She demonstrated the art to the crowds for hours at the shopping center.Ms. Woo began to study the art of Jianzhi as a 14-year-old girl in her hometown in southeastern China. She said all the students at school had to learn the art. However, she developed a special love for it, so her teacher gave her extra training after class. Later, she won second prize in a national painting and calligraphy competition.After Ms. Woo came to the US, she became involved in an event to support and expand the understanding of Chinese paper cutting. She has been invited to demonstrate the art at a wide collection of events. She has also shown her skill at famous museums in Washington. Ms. Woo says paper cutting represents Chinese cultural values, history and stories of people’s lives. She uses the art as a tool to present Chinese culture to people who know little about it.Ms. Woo placed examples of her art around her as she demonstrated paper cutting at the shopping center. Some shoppers, like Ann Russ, took part in a workshop. Ms. Russ was struck (打动) by the finely detailed nature of the work. “ I like to know about the Chinese art, specifically because it is very delicate (精致的). And I like the focus that it requires because it takes me out of everything. And we have to concentrate on something very closely. It is almost relaxing to put that much effort into it. ” Ms. Russ says.8．What can we learn about Jianzhi from paragraph 1?A．It is popular now in the US.B．It dates from the Qing Dynasty.C．It was brought back to life by immigrants (移民).D．It is regarded as the cultural heritage.9．Why did Ms. Woo hold a paper cutting show at a shopping center?A．To earn some money.B．To attract more shoppers.C．To celebrate an art festival.D．To make paper cutting well-known. 10．What is paragraph 3 mainly about?A．The school life of Ms. Woo in China.B．The story of Ms. Woo and her teacher.C．Ms. Woo’s experience of learning Jianzhi.D．Ms. Woo’s success in advertising Jianzhi.11．What can we infer from Ms. Russ’s words?A．She is confused about paper cutting.B．She can get relaxation from paper cutting.C．Paper cutting needs much energy to make.D．Paper cutting takes up much of her time.When did you have a really deep conversation where you felt truly heard? Connections of this kind are completely necessary for people but they are not always easy to find. That’s why one woman decided to take listening to the streets. Her name is Traci Ruble, a therapist (治疗师) who is concerned that people today are experiencing loneliness and lack personal connections. She understands that with busy lives and demanding jobs, people are unable to make these connections.On a spring day in 2015, Ruble and a small number of volunteers set up chairs on sidewalks in 12 locations around San Francisco and invited people passing by to sit for a few minutes and chat. This was the beginning of the nonprofit Sidewalk Talk. The mission is to create public spaces of connections for people. Today, the organization has more than 4,000 volunteers in 40 cities. These volunteers come from a variety of backgrounds and receive training from the organization.Sidewalk Talk gives people a chance to speak and be listened to but it is not therapy. “V olunteers are not communicating as a therapist out there. They’re not there to solve someone’s problems. They’re there to practice being human,” Ruble said. According to Ruble, therapy is one-sided and therapists are taught to avoid self-disclosure (自我表露) but by“being human” volunteers could approach interactions with communication about their own life and by showing sympathy (同情) for the people they talk with.Today, an increasing number of people experience loneliness, according to a report from Harvard University. In fact, 31 percent of all Americans feel serious loneliness including 61 percent of young adults. To deal with that, rebuilding community relationships is vitally important. While Sidewalk Talk will not solve the loneliness problem, these chats could help someone have a brighter day. Knowing that there are sympathetic people who are willing to fully listen and share people’s feelings could make all the difference to a lonely person. 12．What is the purpose of Sidewalk Talk?A．To provide training for those volunteers.B．To teach the passers-by how to communicate.C．To offer public chances of personal conversations.D．To help people reduce pressure at work.13．What is the difference between the volunteers of Sidewalk Talk and therapists?A．V olunteers provide non-professional therapy.B．Volunteers prefer one-sided communication.C．Volunteers are good at showing their success.D．V olunteers express their experiences and feelings.14．What can we infer about Sidewalk Talk from Paragraph 4?A．It makes people more sympathetic to others.B．It offers a solution to the loneliness problem.C．It plays a role in improving people’s feelings.D．It has promoted community relationships.15．What is the text mainly about?A．A woman guiding others to lead an active life.B．An organization taking listening to the streets.C．Therapists setting up chairs on sidewalks.D．V olunteers helping others learn how to talk.二、七选五How to Deal with Stress (压力) at SchoolStress is part of students’ life. While some stress can help them to get work done, too much stress can cause problems with health and sleep. 16 Try one or more of the following.Work out your own learning ways.Students learn in different ways and have different learning styles. Some do homework all at once, while others need to take some breaks. Some students remember well in the morning. 17 So work out your best learning ways and you’ll feel relaxed.Stay healthy and get enough sleep.Many students don’t focus on (关注) their health. 18 Exercising, eating a healthy diet (饮食) and getting enough sleep do good to school performance. When you take care of yourself, you just feel better!Talk to others.19 When you talk your stress out with some friends, chances are that some of them are going through the same thing and they might have some ideas to share. Besides, it helps to know you’re not alone.20You should feel good about taking break. And only you can say which activities work best for letting you relax. Some people find that quiet activities like reading a book or watching TV are the best way to relax. Others prefer more active breaks: working on personal projects, exercising like yoga or Tai Chi, listening to music or spending time outdoors.A．Give yourself a break.B．Share your happiness.C．Sometimes you feel tired.D．However, other students remember well in the evening.E．As a result, their performance (表现) in school and work can be bad.F．Now when you feel your stress building up inside, how can you manage it?G．Share your problems and how you are feeling and dealing with a parent, friend, teacher, or doctor.三、完形填空Standing on the top of Mount Tai, I watched the sun rising through the cloud and takingtop of Mount Tai must be one of the best ways to 22 the beauty of nature.When I left for China, the 23 of climbing Mount Tai had not even 24 me.

We 28 that we are all just students working towards the same 29 of having careers, families and lives and trying to make the world better. Cultural differences seem 30 — even the language almost completely differs from our own. But their daily lives are similar to our own routines (常规). 31 , people worry about the same things we do here. They are 32 food safety, pay close attention to the government and feel the effects of the economic markets.This 33 makes me realize how many cultures my country has in common with other countries around the world.
