On Friday, March 13, my six-year-old son came to home with a pack of worksheets in his backpack. Then I got the terrified email what said school would close for at least two weeks. The COVID-19 quarantine has begun. My initially reaction, after several day of uncertainty and anxiety over if schools would close, was a relief. At least now I would know he was home safe. I spent the weekend dig in my home like the groundhogs in my backyard, setting up classroom on my dining room table, gathering pencils and paper. I thought I wouldn’t have problems stayed calm during quarantine.
With the development of science and technology, intelligent robots will be wide used in the future. In families, robots will help people do some housework and taking care of the elderly, babies and patients. In addition to these task, robots will even be able to play the chess and do exercise with people. In factories, robots will be used to perform some dangerous jobs avoid accidents.
Robots will change our future life by many ways, what will make it more colorful and comfortable. Therefore, we shouldn’t depend on intelligent robots too much, for they were made to help humans rather than replace us. As helpers of we humans, robots should be used properly.

Dear Sir or Madam,
I am writing this letter to draw you attention to the community lecture concerning garbage classification. As we all know, garbage classification is of great significant for environmental protection. We should try our best make our community an better place.
Garbage classification not only benefits the environment, but reduce the workload of workers. More important, it can help us develop a sense of responsibility and form good habits for ourselves. What’s more, the garbage where is classified can be recycled and turned into value resources.
The lecture will be held in the hall at 9 am next Sunday. I hope you can come and join in us. Making a contribution to garbage classification, please.
Yours,
Hongqi Community

Recently, the increasing of shared bikes have made our lives more convenient. However, my classmates and I often noticed some shared bikes place messily everywhere. We felt upset but decided to make a change to the uncivilized behavior. On Saturday morning, we gather outside the subway station. First, we began with those messy shared bikes and tried to put them in to order. People passing by appreciated that we did. Seen the bikes in rows on the pavement, we felt excited. Then, in order to encourage people’s civilized behavior, we put up a largely poster saying “Please Be Civilized While Using A Shared Bike”. Of course, we drew much attention from the passer-by. Hopefully our actions will make difference.
