I was in fourth grade 15 years ago!

It's about how humans flew into the sky like birds by studying them, and so scientists invented airplanes. However, due to the continuous increase in the speed of the aircraft, the wings were shattered, resulting in the tragedy of the plane being destroyed and people killed. Then, scientists found ways to prevent such accidents from dragonflies.

In the past, although the head of a ship was pointy, it could not drive fast, and the whale could easily overtake the ship. Why is that? Scientists have carefully studied whales and found that whales are an ideal "streamliner" with minimal resistance when placed in the water.

A person holds an egg and pinches it vigorously, but it can't be broken. The reason why the eggshell can withstand so much pressure is that it distributes the pressure evenly across its parts. Architects imitated this "thin shell structure" and made many buildings that were both light and economical.

If you don't talk about the topic, how can I do it! Do you want me to buy one? Do you give money? Really!

Officially inform you that there is no door, and there is no money if there is a door!

I'm also in fourth grade, but I don't know, I'm sorry.

For example, list numbers.

a head of black and shiny hair, combed flat to the back of the head, tied into a ponytail, swinging one after another; Under the curved eyebrows, there are star-like shining eyes, and the long figure is like a branch of a weeping willow, graceful and graceful. Walk smartly and elegantly. She is my teacher Ma.

Mr. Ma is caring and teachable.

Mr. Ma is very concerned about his classmates. Once, a classmate reported that Wang Xjing was sick. The teacher hurriedly stopped the lesson that was in the questioning session, and quickly stared at Wang Xjing with concern, as if judging the degree of fever.

Quick, get to the infirmary. The teacher was anxious, but his tone was so soft. It is as if a warm flow flows into our hearts, making people feel special warmth.

Wang Xjing came back from the infirmary, his face was like earth, and he slowly moved towards the classroom step by step, and the teacher looked at him with a worried face and asked, "Do you want to see a doctor?" The teacher's words were concise and soft, as if he was afraid of disturbing him.

Wang Xjing nodded in a low mood. The teacher hurriedly took out the ** and notified the parents, and took Wang Xjing away and sent him to the hospital in time.

Mr. Ma's class is unique and lively. Before each class, Mr. Ma would start with a "brain teaser", and at this time, the students would be so excited that their blood would surge up one by one, raise their hands high, and scramble to answer. Every time you answer, whether it's right or wrong, the teacher will show encouragement with a smile.

When talking about the famous poems and sentences of "Language Garden II", the teacher recited as if singing and not singing: "Wang Wei! Thousands of ravines and trees are towering to the sky, and thousands of mountains are ringing rhododendron ......I was stunned, I had never heard such a reading, I didn't react for a moment, half a piece of wood poked there, and then my thoughts turned like a rolling wheel

It's funny, and there is such a way to read" Later, we read it several times in the teacher's way, and unexpectedly, I easily memorized the author and the content of the poem, and I was able to memorize it proficiently without any effort!

This is Teacher Ma, who taught me our language, like a kind and wise mother.
