Students at a university in Hengyang, Hunan Province, handed over used express boxes for class credits(学分), as part of an effort to raise the awareness(意识) of environmental protection.

After the Nov. 11 online shopping festival, the campus of the University of South China in Hengyang had piles of paper boxes from students’ express orders. They cluttered(使凌乱) the campus environment and badly increased the load of cleaning workers, said Zhang Li, the leader of the event.

Zhang added that the students must sign up online first and give away boxes at recycling sites and get one point for each box, no matter the size. Ten points can be turned into one class credit, which is a must for graduation(毕业).

Students who give away more than two boxes get a beautiful bookmark, and those who give away more than eight boxes get a potted plant.

From Nov. 14 to 20, 2,657 students donated 1.2 metric tons(吨) of boxes, which will be sold by the university. The money will be used to help children and the elderly in the city.

“It’s not only about environmental protection. It also shows that we care for children and the elderly. We are always ready to take part in such activities. They make our school life meaningful,” said student Liang Mini.

There are many volunteers in our community. They are h    1    . They help old people do some s    2     and clean their flats. When there is something w    3     with a neighbour’s computer, a volunteer engineer will come to check it. Some volunteers are ready to help students with their homework and plan some sports a    4     for them. Volunteers also help clean up the community. I would like to b    5     a volunteer when I grow up and help others.

Over the past few weeks, Shanghai has been battling with a COVID-19 outbreak. My community, located in northern Pudong, has been among the worst affected. In order to stop the spread of the virus, it has carried out rounds of all-inclusive nucleic acid（核酸）testing. As a result, volunteers have been in high demand. I have called this community home for nearly twelve years. With a deep love for it, I decided to help out.

My shift began at 6 a.m. on March 16. I was assigned to serve at one of the neighborhoods in the area. There were altogether about 2,500 residents. Neighborhood committee（居委会）workers guided then down group by group to the testing site. Some of the residents had never used the Healthcare Cloud system before. The elderly, in particular, needed help with the registration process. We volunteers showed them how to use the system or registered them for their test using our own smartphones.

Everything went smoothly until about 8:30. A few residents told me that the Healthcare Cloud system was not working. I tried to log onto the system myself and found the service was indeed unstable. The line became longer and longer as more and more people ran into the same problem. It was a hot day. Some people quickly lost their patience and tried to cut in line. Some took off their masks in order to chat with one another. I told them to put their masks back on and to maintain a safe distance apart from one another while continuing to help the residents register for their test.

Some elderly residents with mobility（活动能力）issues were unable to come themselves to the testing site. For these residents, the medical workers provided home service. It was difficult for them to climb the stairs as they were wearing thick protective clothing.

We worked until 3 p.m. When the medical workers took off their protective clothing, I noticed that their fingers were soaked in sweat（汗水）and had become wrinkled. It broke my heart to know that __________ because of the high demand for nucleic acid testing throughout the city. On some days, they were only able to get two to three hours of sleep.

It was a tiring day, but I felt happy that I was able to help out. I sincerely hope that these hard times will soon be behind us.
