专制主义中央集权的制度是中国古代政治制度的核心，这一制度的建立与完善对中国统一多民族的形成与发展产生深远影响。关于这一历史，结合材料分析：

材料一：为稳定周初的政治形势，巩固疆土，周王根据血缘关系远近和功劳大小，将宗亲和功臣等分封到各地，授予他们管理土地和人民的权利，建立诸侯国。──人教版《中国历史》七年级上册

材料二：从政治高度意义上考虑问题，“始皇”这个称号，对他而言，实在是当之无愧。──郭志坤《秦始皇大传》

材料三：秦和两汉应该是一个连续体，不必当做三个朝代来看待，所谓“汉承秦制”。 ──许倬云《大国霸业的兴废》

材料四：统一只是封建君主专制的表现形式……没有君主集权就不会有地区性的统一；没有地区性的君主集权就不会有全国的封建统一。──刘泽华《中国封建君主专制制度的形成及其在其经济发展中的作用》

    It's not just gloves that can help people keep warm in winter. Love can, too.

    A pair of 16-year-old American twins, Jack and Jake Moran, started a program called "Warm Hearts, Warm Hands" last month. Their aim was to collect new and used gloves with fellow students at Richards High School.

    "We started this program a few weeks ago after we saw something on the news about a student who got frostbite(冻伤的）riding his bike to school," Jack said. "I just kind of realized that there are so many kids who don't have or wear gloves. The school has started the collection competition among classes, and the class that collects the most gloves gets a pizza party.

    The twin brothers talked to other students about their program. Many teachers also joined in, bringing in gloves and encouraging their students to help meet the needs of local community members.

    "The conversations we are having now aren't so much about what actions we can take, but about ______▲_____ .This program has really shown me that I don't need to get on a plane and go to help refugees(难民）to make a difference. I can do it right here. I can do it every day." Jake said.

    More than 500 pairs of gloves have been collected in a month and more donations(捐赠品） are coming in every day, including hats and scarves.
