This report describes the problem of wasting electricity and water in school restrooms and suggests several solutions to address this issue.

Nowadays, it is common to see lights left on and water taps running in restrooms even when no one is using them. This situation often happens because students forget to turn them off or do not fully understand the consequences. As a result, a large amount of electricity and water is wasted every day, leading to higher utility bills for the school and unnecessary damage to the environment.

To solve this problem, several practical measures can be taken. First, the school should install motion-sensor lights and automatic taps in restrooms so that electricity and water are only used when necessary. Second, it is important to raise students’ awareness of saving energy and water. This can be done through posters, announcements, and short lessons about environmental protection. In addition, teachers can remind students regularly to turn off lights and taps after use.

These measures will help promote responsible behavior among students and create a more sustainable school environment. Therefore, it is recommended that the school implements these solutions as soon as possible.

The line graph shows population trends in Viet Nam from 1960 to 2020. Overall, the urban population increased steadily, while the rural population declined significantly over the same period.

In 1960, most Vietnamese people lived in rural areas, accounting for around 85%. However, from 1960 to 1980, this figure fell slightly to 81%. From 1990 onwards, the rural population continued to drop sharply, reaching only 63% by 2020.

By contrast, the urban population rose throughout the entire period. In 1960, only 15% of the population lived in cities. This increased to 19% in 1980 and then grew slowly to 20% in 1990. From 2010, urbanisation became faster, with the percentage climbing to 30%, and finally reaching 37% in 2020.

Overall, the graph clearly illustrates Viet Nam’s strong shift towards urban living.
