In the dead of night, the bright lights in the opposite building slowly went out, only a few were still on, and occasionally a few tiny meows could be heard. Tomorrow is the math exam! Sleepy, still trying to solve the problem in the middle of the night.
To me, this question is equivalent to a junior high school question. If this problem is not solved and the analysis is reasonable, tomorrow's score will be "terrible". I always yawn when I try to solve this problem. Besides, it was late at night, no one would turn on the light, and everyone was already asleep. The efficiency of tackling difficult problems in the middle of the night may be reduced, but it must be done for tomorrow's math exam!
At this time, my mother came in with a glass of fresh milk for me to drink. She stroked my head and said softly, "son, let's drink a glass of fresh milk to warm up and cheer up!" " I picked up the fresh milk and gulped it down. I continued to attack the problem, and my mother went out quietly for fear of affecting my attack. I saw her put the cup away, not watching TV, playing with her mobile phone and turning on the light. Instead, she sat quietly on the sofa and waited for me to sleep together. I should cherish every minute now, and I can't use my own time to delay my mother's sleeping time.
Thinking hard, I finally "cracked" this "puzzle". I'll go out and let my mother sleep with me! Don't delay her sleeping time any longer.
Problems in Composition 2 of Grade Four On the road of our growth, there will always be various problems, and I am no exception. Let me tell you something!
After school that day, I happily said to my mother, "Long live the school and the teachers." Mom said, "What's the matter? Tell me about it! " I said, "Today is no homework day." Mother said, "I see, but you have to finish the information." "Alas, my life is really bitter." I said. Let's listen to the boss! But when I opened the information, I was already shocked, almost all of them were Olympic math questions. So, I had the idea of giving up. But I can't help thinking of the poem "Seven Laws Long March" and the ups and downs experienced by Red Army soldiers. Thinking of this sentence, I can't help thinking that all Red Army soldiers can walk through the snow-capped Minshan Mountain, let alone let me write these Olympic math questions.
So, I thought about it, but I really couldn't, so I had to let my mother teach me. Who knows, my mother taught me in two minutes. It's amazing. Then my mother said to me, "You have learned all these questions!" I nodded again and again. She asked me some similar questions. Although I have a hundred grievances, I give myself courage when I think of the Red Army. I finished these questions and my mother praised me after reading them.
This is my difficulty. What about yours? This difficult problem made me understand that no matter what I do, I must persist and think about how the Red Army soldiers walked through Minshan. I think how can we have a good life now if the Red Army soldiers don't insist? They are my heroes. Therefore, we should learn from their qualities, repay them with our excellent achievements and become the pride of our motherland.
On Sunday, I was doing my homework at home, and the following questions puzzled me: measuring the depth and single strand of a well with a rope. After the rope reaches the bottom of the well, there are still 8 meters outside the well; Double strand, after the rope reaches the bottom of the well, there are still 2 meters outside the well. How deep is this well?
I think: when using single strand, the rope length in the well is the depth of the well, and it is 8 meters outside, but why is it 2 meters when using double strand? It should be 4 meters. Is there a problem with the topic?
Out of curiosity, I had to ask the doctor for help. I said a lot of nice things before I moved the doctor here. Dad looked at the topic and asked me to take out a water cup and a wool. I immediately flew into the kitchen to get a water cup, and then flew into my mother's bedroom to get a long wool. I don't know what medicine is sold in my father's gourd, so I have to let my father direct me. Dad asked me to sit next to him and taught me to do experiments according to the meaning of the topic: I first fell the wool vertically to the bottom of the cup, and then made a red mark with a pen to indicate a single strand; The second time I folded the wool in half, slowly put the bottom into the cup, and made a blue mark to indicate double strands. After I unfolded the wool, I compared the distance between the two marks and finally knew the answer to the question.
The test tells me that when measured with a single rope, the length of the rope in the well is the depth of the well; Measured with double ropes, the rope in the well is twice as deep as that in the well. So the difference of rope length measured twice outside the well is the well depth, 8-2× 2 = 4 (m).
The test method is really good. If you encounter problems in the future, you must do it. You can't imagine it out of thin air!
Yesterday, I received a phone call from my fourth-grade nephew: "Auntie, listen to how to do this problem: the two sides are isosceles triangles of 30cm and 70cm respectively. How many centimeters is the other side? "
I was shocked when I heard this. A very simple question came out with a pen. So, I said to him, "You use brush strokes first, and then tell me."
"I won't." The tone of the other party was immediately filled with impatience. "Just tell me the answer directly!"
I don't talk, and he stubbornly doesn't talk.
After thinking about it, I still "compromise": "It should be 30 cm! But, I'm not sure. You'd better draw a picture, or you can call the teacher. "
"Well, I see!" Hearing the answer, my nephew immediately put down the phone, wondering if the answer was right.
After a while, I saw the little guy motionless and knew that he had adopted my "correct" answer, so I called again, "Did you draw that question just now? At this moment, I think 30 cm should be wrong, isn't it 70 cm? "
"ah? You are not sure? " After listening to his nephew's answer, he drew with a piece of paper, paused for a moment, and then replied with a mocking smile: "Auntie is really wrong, it should be 70 cm!"
This guy is definitely a bird waiting to be fed with his mouth open. I tutored him for a while when he was in the second grade. When he meets a problem, he looks up at you and waits for you to tell him the answer. If you talk more, he will be impatient, let alone think independently, especially in Chinese. He won't ask you questions. If you let him find a book by himself, he will be very empty and will quit after he is admitted.
Therefore, during the days when I tutored him, I had a lot of "wits and wits" with him, and even quarreled with him and praised him, which made me very tired. In the end, my Chinese grades only improved a little. They moved back to their grandmother's house far away from us, and then they found two young tutors one after another. People also coax him to finish his homework as a principle. After two years of fooling, I naturally know my academic performance.
A simple topic like this really won't? Many times, I'm afraid the obstacle is not the problem, but laziness. I really hope that he can get rid of the habit of relying on others as soon as possible in the future, turn around rusty little brains more, do more so-called "problems", and finally look at himself in surprise: the original problems are all easy with hands and brains!
