Ask your teacher to write an essay on grinding soybean milk with a soybean milk machine, 400 words.

One day, my mom bought a machine from the supermarket, I looked at it for a long time, but I still don't know what it is, so I asked curiously, "Mom, what is it? What does it do?" Mom said, "This is a multifunctional soymilk machine, you can grind soymilk, you can squeeze juice, grind dry powder, you can also grind meat." I was so happy that I jumped three feet high, because I like to drink soybean milk, in the past, every time I want to eat, have to go to the street to buy, from today onwards, I do not have to leave the house will be able to drink fresh soybean milk.　　As soon as I thought of this, I couldn't wait to say to my mom, "Mom, let's grind the soybean milk! I can't wait!" Mom heard this and immediately burst out laughing, making me confused and pestering my mom to ask what she was laughing at. Mom stroked my head and said, "Son, we can't just grind it, we have to soak the soybeans in water for ?8-10? hours before we can grind white soy milk!"　　Under my mother's guidance, I took three small handfuls of soybeans and put them in a bowl with the right amount of water, and my mother also said that before grinding the soybean milk, the container should be cleaned. After all this preparation, it was a long wait.　　It was hard to wait until the next morning, and I couldn't wait to try it. I carefully put the soaked soybeans inside the filter, and then let the filter stuck in the grinding cup, pour the right amount of water, the lid closed, and then plugged into the power supply, it began to start, the milling knife turned happily, and from time to time issued a "sizzle! Sizzle!" The sound of laughter. Grinding three or four minutes later, "laughter" is gradually becoming smaller, I turned off the power, through the glass container to see, wow! Snow-white, snow-white soymilk was ground out in a few minutes, really amazing!　　I watched, really want to drink it immediately a big mouthful, mom said: "boy, this is not yet able to drink it, raw soymilk poisonous drink will have diarrhea." "We have to put the ground soymilk in a pot and boil it for ?5-10? minutes, you have to watch it, otherwise the boiled soymilk will roam out of the pot, and after boiling it, you have to remove the froth from the top, that way it's good to drink."　　Mom served the soymilk in a cup, I put some sugar in it, stirred it, took a sip, wow! Fragrant and sweet, it was so delicious, I don't know how to describe it, I drank two big cups in a row!　　The soy milk I ground was thick, sweet and tasted so good! Next time you come to my house, I will do it myself for you to drink.
