Li: We have a new theme activity at the class meeting today. You want to know what it is?

Chen: Our content today is about garbage sorting.

Combination: garbage sorting, the city's burden reduction class meeting officially began!

Chen: Everyone is complaining about the people who make rubbish. Li: Everyone makes rubbish intentionally or unintentionally. Chen: Let's ask Li to read an article.

Li: Welcome everyone!

Article:

Many people say that garbage is a "drug" that harms our health and a "bad teenager" that destroys the earth. In fact, garbage is just a misplaced resource, and they also have the value of reuse. Although we have many sanitation workers at present, it is not enough to rely on sanitation workers alone, but also on our consciousness. As long as we consciously throw the garbage into the proper trash can and sort it well, these garbage can be turned into treasure and recycled. This can not only reduce pollution and protect the environment, but also improve the utilization efficiency of the earth's resources. If we sort the garbage, the environment will be very beautiful. Do you know that a ton of waste paper is equal to a tree? If everyone directly wastes a ton of paper, how many trees are there enough for us? Recycling a ton of paper is equivalent to saving a tree, so that we can not only provide waste paper for thousands of people in Qian Qian, but also it is no longer a dream that green trees surround our homes and forests are all over the city. So from now on, let's sort the garbage together! There are many kinds of garbage, including recyclable garbage, non-recyclable garbage and toxic harmful waste. Recyclable garbage includes: newspapers, book paper, wrapping paper, office paper, advertising paper, cartons, plastic cups, mineral water bottles, etc. Non-recyclable garbage includes peels, leftovers, flowers and leaves. Hazardous wastes include: batteries, metals, etc. Each of us has our own family, so the garbage also has its own family. We should put the garbage in a suitable "home". Toxic harmful waste should "live" in the red trash can, recyclable trash can should "live" in the yellow trash can, and green trash can is the home of non-recyclable garbage. It's not difficult to sort garbage, it's just that we can lift a finger. For our homeland, for our tomorrow, from today on, actively participate in garbage sorting, create a beautiful community environment, cooperate with garbage sorting, and strive to be civilized citizens together!

Chen: Thank you for reciting.

Li: Banana battery cellophane.

Chen: I also have my own homecoming day.

Li: Garbage friends and relatives ask each other.

Chen: They are all sorting garbage.

Li: Do you know what harm garbage does?

Chen: Next, we ask Hong to read us the dangers of garbage.

Article:

The earth is our home and provides us with such a beautiful environment. However, with the rapid development of social economy and the high concentration of urban population, the output of domestic garbage has gradually increased, and our home is surrounded by garbage.

General domestic waste can be divided into five categories: waste paper, plastic, glass, metal and biological waste. The main hazards of garbage to human life and environment are:

First, it occupies too much land. Garbage piled up in the suburbs of the city occupies a lot of farmland. Garbage stays in nature for a long time: cigarette butts and woolen goods 1-5 years; Orange peel for 2 years; 80- 100 cans; Plastics 100-200 years; Glass 1000.

Second, pollute the air. Garbage is a complex mixture. In the process of transportation and open-air stacking, the decomposition of organic matter produces stench, which releases a lot of pollutants such as ammonia and sulfide into the atmosphere, including 100 kinds of volatile organic gases, which contain many carcinogens and teratogens. Plastic film, paper scraps and dust fly with the wind, forming "white pollution".

Third, pollute the water source. Harmful components in garbage are easily washed into underground water by rainwater, and a large number of acidic and alkaline organic pollutants will be produced during garbage stacking or pit filling, and heavy metals in garbage will be dissolved. If garbage is directly thrown into rivers, lakes or oceans, it will cause more serious pollution. Look: plastic bottles and lunch boxes floating on the surface of Qinhuai River, plastic bags and bread paper hanging on the branches. Not only causes environmental pollution. And if animals eat white garbage by mistake, it will not only harm health, but even die.

Fourth, fire hazards. Garbage contains a lot of combustible substances, which will produce methane and other combustible gases during natural stacking. In case of open fire or spontaneous combustion, it is easy to cause fire and garbage explosion accidents, causing heavy losses.

Fifth, the nest of pests. Garbage not only contains pathogenic microorganisms, but also provides food, habitat and breeding places for mice, birds and mosquitoes and flies, and is also the root of infectious diseases.

Chen: Next, let's play some games to relax!

Li: The first game is "Let me guess what you do".

Chen: The rule of this game is: when we tell the classmate who is doing a word, the classmate will do the action and speak to remind the classmate who is guessing, and then the classmate who is guessing will guess what the word is. Remember, students who are doing actions can't say any word of the word, otherwise it's a foul and doesn't count.

Li: The second game is "Looking for Idioms". The rule is: please send one representative from each of the four groups to participate in the competition. Look at the blackboard, please. There are many words mixed together on the blackboard. There are many idioms mixed in it. Ask four representatives to find out these idioms. Add ten points for each idiom you find. In five minutes, whoever scores the most points will win.

Chen: Not much to say, let's start the game now! Is that classmate willing to come up?

Li: This class meeting is coming to an end.

Chen: Have the students learned anything?

H: I declare this class meeting over!
