Are GM（转基因的) foods safe for people? Can they help solve the poverty problem? They have been the subjects of a hot debate.
This debate is related to increasing challenges from rising climatic change, population growth, urbanization（城镇化), and natural resource consumption. According to the Food and Agriculture Organization, food production needs to increase by 60 percent by 2050 in order to feed 9 billion people. Scientists and policymakers are searching for effective ways to gain nutritious food, for today and future. Unlike previous agricultural methods (such as the Green Revolution), GM crops are to fight food safety and poverty challenges.
The great expansion of GM crop varieties over the last two decades can be seen easily. The total area devoted to GM crops has increased 100 times from 1.7 million hectares in 1996 to 170 million hectares in 2012. Developing countries now grow more GM crops than developed countries (in terms of area), largely driven by Brazil’s rapid adoption of GM crops. China is home to about 4 percent of the total global area devoted to GM crops. Beans, corn, and cotton are main global GM crops, while China’s focus is on cotton, papaya, and poplar.
Recently, a scientific study shows that GM crops are safe for people and the environment. According to a 2010 report on the safety of GM crops by the EU, “the main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 research groups, is that biology methods, are not more risky than traditional planting technologies, for example.” Other international and national scientific bodies, such as the World Health Organization, have reached the same conclusion. Nowadays, people are developing GM foods mainly to fight against______.

The meaning of the word “volunteer ” may be a little different in different countries, but it usually means “one who offers his or her services.” There are many different ways in which people can volunteer, such as taking care of sick people, working in homes for homeless children, and picking up garbage(垃圾) from beaches and parks. Volunteers may work within their own countries or in other countries. They are often people with a strong wish to help those who are less fortunate than themselves. Volunteers don’t expect any kind of pay.
At the root of volunteering is the idea that one person may have the ability to offer services that can help other people. Tracy, a good friend of mine, however, recently came back from India with a new idea of what being a volunteer means. She worked for two and a half weeks in one of Mother Teresa’s homes in Calcutta. The following is her story.
“I first heard about Mother Teresa in my high school, we watched a video(录像) about her work in India and all over the world. I was so moved by her spirit to help others and her endless love for every human being that after I graduated from high school, I too wanted to try her kind of work. So with two friends I flew to Calcutta for a few weeks.”
“I was asked to work in a home for sick people. I helped wash clothes and sheets, and pass out lunch. I also fed the people who were too weak to feed themselves and tried to cheer them up. I felt it was better to share with them than to think that I have helped them. To be honest, I don’t think I was helping very much. It was then that I realized that I had not really come to help, but to learn about and experience another culture(文化) that helped improve my own understanding of life and the world.”According to the text, a volunteer refers to a person who ______.
| A．is willing to help those in need without pay |
| B．can afford to travel to different places |
| C．has a strong wish to be successful |
| D．has made a big fortune in life |
Tracy started her work as a volunteer _______.
| A．after she met Mother Teresa | B．after she finished high school |
| C．when she was touring Calcutta | D．when she was working in a hospital |
Why did Tracy choose to be a volunteer?
| A．She liked to work with Mother Teresa. |
| B．She had already had some experience. |
| C．She was asked by Mother Teresa’s example. |
| D．She wanted to follow Mother Teresa’s example. |
What is Tracy’s “new idea” (Paragraph 2) of being a volunteer?
| A．Going abroad to help the sick. |
| B．Working in Mother Teresa’s home. |
| C．Doing simple things to help the poor. |
| D．Improving oneself through helping others. |
How I Turned to Be Optimistic
I began to grow up that winter night when my parents and I were returning from my aunt's house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see-—the strange and magical places I had known only from books and pictures. The country I was leaving never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to "the hard times."
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: almost all common troubles eventually go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.How did the author get to know America?

Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his now place and meet his friends.
My earliest memories of my father are a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. As a child I loved him; as a school girl and young adult(成年人)I feared him and felt bitter about him. He seemed unhappy with me unless I got straight A’s and unhappy with my boy friends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.
On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical(挑剔的)air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?
The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.Why did the author feel bitter about her father as a young adult?

Most people who live in Seattle, Washington, love their city. There is a never-ending flow of fun things to do. But, people who live there do not always enjoy the day-after-day absence of sunshine during the winter months.
It is documented fact that sunshine (or lack of it) plays a major role in how each of us meets the day. It also affects how we perform at school or work. When people are derived of sunlight, they can develop seasonal affective disorder, which makes it difficult for them to feel happy or get things accomplished. No major city in the United States is more affected by the “sunshine factor” than Seattle.
To fight drizzle and fog during the winter months, Steve Murphy created a business that is very popular among the locals. The Indoor Sun Shoppe is more than a little ray of sunshine during the gray days of Seattle’s winter. His shop offers a huge source of plants and artificial lighting for people who are trying to overcome seasonal affective disorder.
Located in Fremont, Washington, The Indoor Sun Shoppe has an amazing collection of exotic plants and “good bugs” in a humid and well-lit environment. At The Indoor Sun Shoppe, you can spend up to $400 for artificial lighting that will chase away the winter blues. It will also keep your plants healthy. You can buy a dawn simulator that will gradually fill your room with a warming wake-up glow. What better way to meet a Seattle morning when real sunshine is nothing more than a happy thought!
Murphy’s in-home waterfalls are also popular with customers. But his plants and lights remain the “main course.” On a cloudy winter day, The Indoor Sun Shoppe is a bright spot in Seattle!Which of the following statements is NOT TRUE according to the passage?

Once you’ve tasted the joy and freedom of an all-access backstage pass, sitting in the balcony（楼厅） far from the stage has little attraction. In March of 2008, I had the opportunity to tour with a band. The experience was eye-opening.
I hadn’t realized how many misconceptions I had about the lifestyle of a world-class musician. Such a life is not as great as it appears. In fact, some aspects are extremely tedious. Hours and hours are spent waiting. The musicians wait for their transportation; they wait for the sound check; they wait to perform. After the show, they wait for the crowds of fans to go away.
When the musicians are not waiting, they are traveling. Sometimes the travel itself can seem attractive and exciting, with the limousines（豪华轿车） and the first-class seats on the plane. However, even these luxuries cannot make up for long, boring hours on the road or in the air. Basic needs are all but ignored. Late-night shows and early wake-up calls make them know the preciousness of sleep. The demanding travel itineraries（行程） and show schedules make regular meals impossible.
In spite of the sacrifices, life on tour has its advantage, at least for the talent. A support team generally travels with the band, with at least one person dedicated to meeting the musicians’ needs at all times. The musicians are expected to perform at the shows, but they are not expected to manage any detail of their lives. When I was with the band, I poured glasses of grapefruit juice, made sandwiches, prepared dressing rooms, and performed all kinds of routine work, such as buying toothpaste and getting money from the ATM. In addition, efforts are made by promoters to keep the musicians happy. Most places offer private dressing rooms for the musicians. There is also usually a green room, a room that is large with comfortable furnishings where the band can visit with friends and family while waiting to go on stage. Before the band goes on, their families and friends file out into the auditorium and find their seats. The house lights go dark and curtain rises. When the lights flash on and the band starts playing, the scene is magical. A behind-the-scenes view makes the experience even more spectacular.The underlined world in paragraph 2 probably means _____.

We can infer from the third paragraph that _____.
| A．good arrangements always make the trips comfortable and pleasant |
| B．most musicians would rather travel long distance than wait |
| C．most musicians ignore their basic needs because the travel is too luxurious |
| D．the lack of sleep and irregular meals seem to be a part of the life of musicians |
Which might be the best title for the passage?

| C．My Part-time Job. | D．How to Make Musicians Happy. |
