    Did you spend much time lying on the comfortable sofa at home during the summer vacation? How often did you do sports this summer? People across the world need to get moving, according to a new study by the World Health Organization (世界卫生组织).

    5% of adults do not get enough exercise, according to the study. This number hasn't changed from 2001. Because of this, about 1.4 billion people are close to deadly diseases (疾病) such as heart disease and cancer (癌症).

    People should do at least 2 and a half hours of "moderate intensity (中等强度)" exercise each week, such as dancing or swimming. They can also do 75 minutes of "vigorous intensity (高强度)" exercise, such as running or playing soccer, according to the WHO.

    As for how to exercise more, experts says that we don't have to go to the gym (健身房) every time For example, we can go up and down stairs (楼梯) a lot instead of taking the lift. If we can't go to a dancing class each week, standing on one leg for 30 seconds a day is very good too.

    The study also found that women are less active than men, 32% of women hardly ever take exercise, compared to (比较) 23% of men. Women spend more time at home taking care of children and doing housework.

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).
