　　(2016·兰州一诊)Many Chinese kids, known as “left­behind” children, hardly ever see their parents, because their parents are migrant workers.

　　Li Ling, 11, is a left­behind child. Her parents have been working in Zhejiang for 10 years, while she lives with her grandparents in Guangdong. She was reunited with her parents last Spring Festival. As the number of migrant workers in China increases, the number of left­behind children is rising fast. Li is one of the 61.02 million left­behind children under 17. They account for 37.7 percent of rural children and 21.88 percent of all Chinese children.

　　“The large number of left­behind children has already become a social issue. If left unsolved, it will cause serious problems，” Wang Zhenyao, director of the China Philanthropy Research Institute, told China Daily. The education level of adults supervising(监督)these children is generally not that high. They can only take care of the children’s personal safety and daily living, being unable to care for their educational and spiritual needs. Meanwhile, the absence

　　of parental support will make some left­behind children lack self­confidence. They may be slower in physical and emotional growth than their peers. Others may even become “problem youths”．

　　To solve this problem, the government is taking action. For instance, 30 provinces and cities have allowed certain children to attend school and take the college entrance exam in the city where their parents are. However, Wang suggested that the country do more, such as making policies encouraging migrant workers to work in their hometowns. He also said that a well­balanced child welfare system is needed. “These children are the future of the nation, so they deserve our loving care and protection，” Wang said.

　　(2016·江南十校“协作体”高三联考)The National Park Service in the United States will mark its one hundredth anniversary in 2016. As it nears its second century, the Park Service plans to increase its educational programs for students and teachers.

　　The plans include transportation support for one hundred thousand students each year to visit national parks to learn about nature and history. Yellowstone is believed to have been the world’s first national park when it was established in 1872. Other students will get a chance to see parks in faraway places through Skype and other online programs.

　　The National Park Service also works with partners to provide education. One of its partners is a nonprofit organization called NatureBridge.

　　NatureBridge is

　　celebrating

　　its

　　fortieth anniversary and says one million young people have taken part in its programs. The organization works with students from kindergarten through twelfth grade and uses national parks as its classrooms. It provides field science programs at Yosemite National Park and four other locations in California and the northwestern state of Washington.

　　Now, NatureBridge is launching an East Coast center with a four­million­dollar grant from Google. The program will begin in April at the Prince William Forest Park in Virginia. Students stay for three to five days in NatureBridge programs. The activities are aimed at developing their science skills.

　　For example, they learn about different soils and study water quality under a microscope.

　　Jason Morris is executive vice president of NatureBridge.

　　He says when they are not sleeping, eating or in a laboratory, the students spend their

　　time outdoors. Julia Washburn is associate director of education and interpretation for the National Park Service. She says in a time of budget cuts, the agency has to find ways to still meet its goals. Ms. Washburn says one of the most important services that the Park Service provides every day is nature interpretation. Park rangers (公园管理员) try to make visiting the outdoors more meaningful. Interpretation is a form of informal education. Essentially, it is a word that we use for the people in parks that explain the park or help orient (确定方向) you. So park rangers are interpreters. They orient you to the place you are in and help you make connections, emotional and intellectual connections, with the place.
