1. Today, my mother took me to the market to buy food. I found a rectangular electric appliance on each booth, which was marked on the front: kilogram gram. I asked my mother curiously. My mother said that the grams and kilograms you just saw are used to weigh things and express weight units. When I got home, I found a lot of things at home: a box of tea 125g, a box of lipstick 48g, milk1.5l. Then my mother told me that all solids that can be picked up by hand are represented by grams, and liquids that cannot be picked up by hand are represented by L. I don't know much about life.

I can meet it everywhere in my life. Every time my mother comes back from shopping in the supermarket, I will carry it with my hand, roughly estimate its weight (how many grams or kilograms), see how much it differs from the actual weight, and then write it down in my notebook. Today, I also met an interesting thing. My uncle came to my house for dinner and said that he had lost weight again and his weight had become 65. I think: is it 65 kg or 65 kg? If it's 65 kg, it's more than ten kg heavier than me. Then I asked my uncle, "Uncle, your weight is 65 kilograms, right?" My uncle said, "Yes, it is 65 kilograms, which is equal to 130 kilograms." I had a false alarm. If I take it as 65 kg, how thin it will be!
