Anonymous users2024-02-05The most tenacious life.
Let me ask you a question: What is the most tenacious plant in the desert? You'll definitely say:
Cactus! "That's right! But I don't think so, cacti can grow in the desert or not by groundwater?
But since that time I've changed my mind ......
I have a pot of cacti at home. Mother often watered the cactus and other flowers, loosened the soil and pruned the branches, so the cactus grew very well. The turquoise flake trunk, dark yellow spikes, and tweed!
Every day, it always stands upright, like a warrior guarding the frontier. This is still true for spring, summer, autumn and winter. Once, our family went back to our hometown to play, and only came home a month later.
And those flowers were watered last month. As soon as I got home, I changed my clothes and went straight to the balcony. As soon as I entered, I saw that many of the flowers had died down, and the better ones were like frosted eggplants and they were all sunburned, (it was summer!).
Only the cactus still stands proudly, looking proudly at the other flowers and plants. Confused, I grabbed some of the soil in the cactus pot with my hand, and when I pinched it, there was not a trace of water. I was blown away and said to myself:
This cactus really deserves to be called the 'desert fairy', "The vitality is so strong, huh?" Shouldn't I also learn the spirit of cactus? It grows in a harsh environment but grows better than any plant.
I also have to study in some difficult environments, not afraid of difficulties, not afraid of difficulties, and move forward bravely. I think this is what it means to "grow up in a difficult environment and grow stronger". The cactus, it does not have a beautiful appearance but has tenacious vitality, it does not have wide branches and leaves but has a shield against foreign enemies, it is not sought after by people but has a beauty that outsiders cannot see!
The vitality of cacti is so tenacious!
The most wonderful life.
It is short-lived, but in this short period of time, there is the most beautiful and wonderful life. Life is short, but it will be very fulfilling and fulfilling to let the finite life shine in wonderful moments.
I remember a news item that said: "There was an accidental fire in a clothing building in a certain place, and after the fire brigade arrived, several firefighters rushed into the fire in front of them in front of them, regardless of their lives, to rescue the employees trapped in the disaster field." After saving one person after another, they still rushed towards the raging fire again and again.
It was cold and the firefighters' feet were frozen with dripping water. The water pipes were also frozen, and in this case, desperately rushed to the fire.
After a long time, when the threatened people were rescued one by one, when people were tired of waiting with bated breath waiting for the heroes to come out of the fire, when the rescued people and their families felt happy, suddenly, the building collapsed! Several heroes disappeared in the fire ......

Anonymous users2024-02-041. Good luck 2 times, bad luck 3 times. For the first time, 5 packs on both sides and see which side is lighter. The second time, the light 5 packs, choose 4 packs, 2 packs on both sides, if the same weight is the remaining pack, if which side is light, put a pack on each side, observe which side is light.
2,3 Same approach.
4，6*46=276km 276*2=552km 552/

Anonymous users2024-02-03It's not your average math problem=. =
The first question, take 5 packs each, put them on the left and right, take out the five light packs, take out one pack from the heavy ones, repeat the first time, take the light ones, leave three packs, take another pack, weigh them, leave two packs, and compare the remaining two packs, the light ones are not good, and they are altogether.
The second question and the first question are almost simpler, the county six packs said, if the weight is the rest of the pack, if not, you follow the first question method.
I don't know the third question, but I still have to think about it.
Question 4, 46*6*2 (6+.)
