    【题目】

    A college graduate（毕业生）from Shanxi named Wu Jun created a 9-page “WeChat guide”. With drawings and simple words, the step-by-step guide explains how to send messages, take pictures and make video calls. Wu made the guide for her parents. “My parents are getting old. They need an easy way to learn how to use technology, she said.

    Wu’s experiences is common nowadays. Worldwide, 40 percent of parents learn about new technologies, including computers, mobile Internet, and social media（媒体）, from their children, according to a study.

    Parents used to teach their kids about almost everything. Now for the first time, the teachers become the students, while the students turn into the teachers.

The young generation usually acts as a link（桥梁）between their families and the new environment. When they teach their parents new technologies, parents can connect to the new world by themselves.

    【题目】Would you like to experience what going to school was like in the late 1800s? To start with, imagine everyone in only one classroom.

    In the 19th and early 20th centuries, most American students went to a one-room schoolhouse. A single teacher would typically have students in the first through eighth grades, and she taught them all. The number of students varied from six to 40 or more. The youngest children sat in the front, while the oldest students sat at the back. The teacher usually taught reading, writing, arithmetic(算法), history, and geography. Students memorized and retold their lessons.

    The classroom of a one-room schoolhouse probably looked much like your own. The teacher’s desk stood on a raised platform in the front of the room, however, and there was a wood-burning stove since there was no other way of heating. The bathroom was outside in an outhouse.

    In Honeoye Falls, New York, there is a one-room schoolhouse where kids today can experience what it was like to the students in the late 19th century. For a week during the summer, they wear 19th century clothes and learn the way children learned more than a hundred years ago.

    What else has changed about school since the 19th century? For more information, please visit our website: www. Locallygacy.com.
