The winter holiday is usually a good time to sleep in. But Gao Yuqi, a 14-year-old boy from Jiangsu, got up at 7 a.m. to run at least 2 kilometers every day during the holiday.

【小题1】 Gao was not alone. Many schools across the country asked students to exercise during the winter holiday. Part of the reason is that physical education test scores are now worth more on the senior high school entrance examination In Jiangsu, the score is now worth up to 40 points.   【小题2】

Because of this, Gao’s school asks students to run on sunny days and exercise indoors if the weather is bad. 【小题3】 They must make a plan for it. They have to skip rope (跳绳) for two minutes and do three sets of sit-ups each day. Their parents sign off on their plans after they finish exercising.
