Back and forth

Speaking of waste batteries, it can be a big pollution! Within a month of landfill treatment, the metal shell of the waste battery will be corroded and perforated, and the harmful substances in the waste battery will enter a soil and water body, causing pollution to the environment. According to environmental experts test, if six tons of household waste mixed with a mercury-containing battery, when the waste landfill, the concentration of mercury in the soil will exceed the safety standard, it will not be able to grow vegetables; If the waste battery is mixed with household waste into the incineration plant, mercury, cadmium and other metals in it will be vaporized and discharged into the atmosphere at high temperature, which will pollute the atmosphere and affect human health. If a waste battery is put into the water, the water within a few kilometers will be toxic and undrinkable. Therefore, we should learn to collect and dispose of waste batteries. In my life, I often collect some waste batteries, such as: No. 5 battery, mobile phone battery, No. 7 battery and so on. I often put them into envelopes and put them into the bookcase in the living room. Puzzled by my actions, my grandmother would often say, "Hang Hang, what are you collecting these batteries for? "Is it green?" "Go green! If you study well!" Although my grandmother objected, I persisted, and if there were any old batteries, I still put them in envelopes and put them in the bookcase. In this way, I collected for two months, finally can dispose of these waste batteries. Today, we came to RT-Mart shopping mall, in a corner of the counter, there is a plastic box, which is specially collected waste batteries. I put the dozens of waste batteries into the box, I was very happy, because I found a home for the waste batteries. I really hope that if everyone collected and disposed of waste batteries like me, the land and water would not be polluted, and they would be greener and bluer.....

The days are like a trickle, passing through the fingers of each finger, the footstep of the pedestrian on the black stone road, back and forth, back and forth. That plain thick mud brick wall, precipitate the trace of history. The morning ripples pale, in the corner of the eaves drop into a warm. The sun, reflected in the corner of every person's brow, brewing a hazy golden light, such as a dream, such as fantasy. The dull day into a poem, in poetry leisurely forward, chew the days into a prose, although the day to the countryside will meet all kinds of unsatisfactory, we are painful and happy. In the logistics activities, encounter all kinds of dissatisfaction, the rice is not cooked, the food will not do, difficulties, in the publicity activities, hard to write every day, to the major website submission, will encounter rejection, feel every day. When teaching, we should take care of every child's emotions, control the classroom atmosphere, and maintain good classroom discipline. Sometimes, it can not meet the requirements of every child. When I go out for research, I sometimes meet a lot of people's rejection. Sometimes, because of the language barrier, the research work is very difficult. But fortunately, we still persevered, more setbacks more courage, believe that every day is better. At the end of a busy day, you can relax and appreciate the gains of the day. Whenever this time, guitar and music, in the company of the moon and stars, in the gentle breeze comfort, we safely fall asleep. I put my hands together, prayerfully, delusion to retain the footsteps of the goddess of time. If I may, I'd like to sing myself to you. Please listen carefully, our fearless, our courage, our persistence.
