A weekend in this music paradise  just seems too short. Besides, a brand new world-class outdoor theater has just been open at this year's festival, which will surely make the festival a better and more permanent experience. A full house is before the new outdoor amphitheater  . Even the thunderstorm couldn't break up the crowd completely absorbed in the music. Thanks to the new theater, this year's Great Wall Forest Festival offers even more superb acoustics and an overall outdoor theatrical experience, even though the project is still half complete. The festival is now in its fourth year. Since its first show in 2010, the festival has seen a steady increase in festival-goers and has expanded its length from two days to four days, divided over two weekends. It has also been experimenting with a variety of styles, from classical to pop, with this year's theme "Celebrating 20 Years of Chinese Folk Song." Folk Song legend Lao Lang explains how folk songs have helped encourage more amateur folks to express themselves through music. "Before music was reserved for the professionals.

It's popular music and it always has a story." said Lao Lang. Unlike some of the other outdoor festivals, the Great Wall Forest Festival appeals to a wide range of audiences. It's a rare place where teens, parents and families can all enjoy the outdoors and have a great time. Great music and scenery aside, many children's workshops, master music classes, and interactive art activities have also been introduced this year.

Q: Read the following article and answer the question. Article: Breathe, wave and smile. Along with more than 300 other seniors, I marched into the stadium on the afternoon of May 10. The audience burst into deafening cheers. The huge stadium shook with all the whistling and clapping. It was as if a Hollywood superstar had walked on stage. And indeed, every single senior that day was a star of the moment. Each deserved it. The seniors had been preparing for four years for this once-in-a-lifetime moment--the commencement . Seated, I waited anxiously for the opening address. As a foreign exchange student, I was not able to receive a diploma. However, I still had the wonderful feeling of being part of things. Like the other graduates, I was dressed in marron cap and gown . Our principal, Mr. Glover, delivered a short, warm greeting. The US national anthem followed and then, hands on chests, a solemn Pledge of Allegiance . Students who had excelled academically gave farewell speeches. The tears in some eyes convinced me that many had deep feelings about the occasion. It was as the class motto says, "Life brings us tears, smiles and memories. The tears dry; the smiles fade; but the memories last forever." Then came the core   of the commencement. Hundreds of names were announced. Each graduate walked across the stage to receive his or her diploma from the principal. From the different cheers each graduate got, we had the funny sense that it was a kind of competition of who could cheer the loudest. To be honest, the presentation of diplomas got boring. A girl sitting next to me even started yawning. But it wasn't boring for those receiving the diploma: they would treasure the moment the principal placed the sacred brown document in their hands for the rest of their lives. A new page in the book of that person's life had turned. They were glimpsing their futures: futures of challenge, hardship, perhaps loneliness too, which would take all of their courage. Question: From the text, we can conclude that  _  . Answer:
A: the commencement symbolizes the beginning of a new stage in life

Q: Read the following article and answer the question. Article: It is pretty much a one-way street.While it may"be common for university researchers to try their luck in the commercial world,there is very little traffic in the opposite direction.Pay has always been the biggest _ ,as people with families often feel they cannot afford the drop in salary when moving to a university job.For some industrial scientists,however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70%cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge.Her main reason for returning to academia halfway was to take advantage of the greater freedom to choose research questions.Some areas of research have few chances of a commercial return,and Lee's is one of them. The powerful effect of a salary cut is probably less severe for a scientist in the early stages of an occupation.Guy Grant,now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge,spent two years working for a medicine company before returning to university as a post-doctoral researcher.He took a 30%salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder,where a pay cut is usually more significant,the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive,according to Lee.Industrial scientists tend to receive training that academics do not,such as how to build a multidisciplinary team,manage budgets and negotiate contracts .They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate,says Lee,perhaps experience in manufacturing practice or product development."Only a small number of undergraduates will continue in an academic occupation.So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who...
