A university professor recently made several tests with different animals to find out which was cleverer than other animals.

    In one test the professor put a monkey in a room where there were several small boxes. Some boxes were inside other boxes. One small box had some food in it. The professor wanted to watch the monkey and to find out how long it would take the monkey to find the food. The professor left the room. He waited a few minutes outside the door. Then he got down on his knees and put his eye to the keyhole (钥匙孔). What did he see? To his surprise, he found himself looking into the eye of the monkey. The monkey was on the other side of the door and looked at the professor through the keyhole.

Feb. 17 should have been the start of the spring semester for many middle and primary schools in China. However, to control the spread of the COVID-19, many schools had delayed the start of the semester, following instructions from the Ministry of Education (MOE). But students in China were still studying.

Instead of having classes at school, many students in Beijing and Guangzhou began their first day of online classes on Feb 17. Students in Shanghai started online classes on March 2. "In the morning, I have English class, followed by Chinese and math, " Liu Bo, a Junior 3 student from Beijing, told Xinhua. "I have also learned about epidemic(流行病) prevention. "

According to the MOE, students were mainly taking classes to review previous knowledge rather than taking new classes during the online study period. Online courses were required to include contents about epidemic prevention, psychological health (心理健康) and educational activities (教育活动).

"Online courses are only temporary measures (暂时的措施) taken during the epidemic, so when the new semester begins, schools should not replace(替代) classroom teaching with online classes, " Lu Yugang from the ministry told China Daily.

The ministry also called on schools not to increase their students' schoolwork burden(负担). Schools should not ask students to study online for long periods of time or study things beyond( 超出) their curriculum(课程). Students must have enough time to rest, the ministry added. Also, it stressed that protecting students' eyesight must be a priority(优先).

Her hard work finally paid off. Now 26, Yang has made a name for herself as a dancer on a bamboo pole. People can't believe their eyes whenever they watch her performances. Through Yang's dances, many people now know about bamboo drifting. They have discovered the beauty of this traditional skill.
