Do you know the look of wonder and joy that children get on their face when they listen to someone reading them a story? Schools across the nation are bringing in volunteers to guide children in this very way. If you simply enjoy spending time with children, being a reading volunteer can be a great way to help support the upcoming generation of readers.
Reading volunteers work with elementary school age children to promote reading. They may read books to children, listen to children read aloud, or distribute books to school children. Reading volunteers promote the activity of reading, rather than focusing on teaching reading skills. They may read to a whole class of children, to a small group, or be assigned a child to read to one-on-one. During the time they spend with new readers, reading volunteers encourage them to learn to read.
Almost anyone who knows how to read can be a reading volunteer. High school students, college students, parents, grandparents, and police officers are just an example of the kinds of people who become reading volunteers. Being able to read and wanting to spend time inspiring children to read are the only skills needed to be a successful reading volunteer.
Several educational research studies show that children who are involved in programs with adult reading volunteers improve their school performance levels. For example, in 1998, researcher Sara Rimm-Kaufmann found that first graders involved in a program with an adult reading volunteer three times a week had better letter recognition and reading skills than similar first graders who hadn’t been involved in such groups. In 2000, the Eugene Research Institute found that fifth graders who had been in “SMART”, an adult volunteer literacy program, were 60% more likely to have grade-level scores in standardized reading tests. Moreover, a 2006 study by Brian Volkmann showed that children who were read to by adult volunteers had improved school attendance, which is a major predictor of high school graduation rates.
In addition, reading volunteers themselves can gain a lot of benefits that range from expanding their personal networks to adding valuable skills to their resumes. They also enjoy the special time they get to spend with young children. Many volunteers have heart-warming stories to share with the children they read to. The volunteers know that they are inspiring young children with a proved educational strategy. So, if you have time, energy, and skill to support children’s literacy, it is a good idea to sign up to be a reading volunteer.

Now that newsrooms are becoming less popular in the US，young people have begun to tell their own stories．

GlobalGirl Media，a nonprofit organization that teaches teenage girls digital storytelling skills，was started by award-winning filmmakers Amie Williams and Meena Nanji in Los Angeles in 2010．

“By giving girls a voice，you introduce a different story，and change the existing one，”said Danny Glover，a member of the GlobalGirl Media advisory board．

“When the camera’s in my hands，I feel like I can’t lose，”Said Cheyenne Grisez，14．“It makes me happy and I feel like I can do anything．”

On the final day of the summer academy in California，Williams worked with Grisez and Camila Prado，15，on a short film about Prado’s fight against an eating disorder．In the film，Prado bravely interviewed her parents and sister about how she was able to beat her depression and eating disorder．This film and others the girls had made were shown to parents and friends on the last day of the academy，celebrating their hard work．

“It’s their story，and nobody knows how to tell it better than they do，”Williams said．

“These girls are from really difficult backgrounds．They feel trapped sometimes．They feel alone．”Williams said．“The camera gives them a way to look at their world in a different way and get out of that feeling．’’

Girls in the program practice their skills and build confidence by going out in the community and interviewing people for the short films．Many of them had no experience，but found they had good storytelling skills．

“I work with these girls．Every day I leave inspired and completely grateful，because I know that．due to the work we're doing with them，things will be better，”said GlobalGirl Media summer academy project director Heather Faison．

29．Why do many American girls like to tell stories using the camera?

  A．Their parents hate to give them a hand．

  B．The camera can help them out of their trouble．

  C．They can make profits from their documentaries．

  D．They desire to improve their photo skills．

30．What do we learn about GlobalGirl Media from the text?

  A．It gives girls digital storytelling skills．

  B．It gets much money from girl students．

  C．It was founded by the government．

  D．It has newsrooms in California．

31．What difficulty did Prado overcome by making her film?

  A．Self-harm．            B．An eating disorder.

  C．Poor school scores．  D．Teenage depression．

32．Who directed GlobalGirl Media summer academy project in California?

  A．Meena Nanji．         B．Amie Williams．

  C．Danny Glover．       D．Heather Faison.
