Ding Yu ......"The class bell rang. The teacher walked up to the podium with a smile on his face and wrote "locust" on the blackboard. Oh!

So we're going to have this class today. The teacher asked us to catch locusts so that we could observe and learn about locusts. The teacher said kindly

Locusts are no strangers to all of us, please read a paragraph**. Subsequently, the teacher used the "multi**projector" to ** a paragraph about locusts. The students watched intently.

It turns out that the body of the locust is divided into three parts: head, thorax, and abdomen. The hind legs have well-developed muscles that allow them to jump ......I didn't expect this little thing to be so powerful!

To confirm the role of the locust's hind legs, the teacher took out a locust. Poke it lightly with a stick, and suddenly, with "Wow"! There was a bang.

The locust kicked on the table with its hind feet and jumped onto the opposite desk. is also constantly flapping his wings, like a pot-bellied general who has won a battle. "That's amazing!

Let's see what's changed? Scold! The locust died.

That's when I realized that it was the locust's valve, the gateway for gas to enter and leave the body. Because in the water the locusts could not breathe and suffocated to death. I didn't expect the little locust to have so much knowledge.

Next, students are invited to observe locusts and learn about locusts in combination with textbooks. In the classroom, the students were talking and expressing their opinions. From time to time, bursts of laughter rang out, echoing through the classroom.

Ding Yu ......The bell ended this fun biology class.

The forehead above the small eyes of the beams of the small window looks like it is made of firewood that has been chopped haphazardly. **Dirt and dirt, lacking luster, as rough as the exterior wall of a cottage made of branches, in the middle of the four faces, we see a wide, two-hole lion's nose, as if it had been crushed by a human fist.

Two thick lips are born in the middle of the sunken cheeks. The general impression left is that it is disorderly, rugged, mediocre, and even vulgar.

You, a classmate, don't study hard yourself, even if you still influence others, trying to pull others into your own bed of depravity, what kind of intentions do you have? Can you be responsible for the future, worthy of your parents' early and late nights? I don't want to say too much, although I have said a lot, but I must emphasize that if you continue to fool around like this, sooner or later you will be the one who will be fooled.

How many sons is it? How many miracles have you created, how much power have you contained, and how big is your heart? In front of the boundless sea, man and nature blend, all thoughts are silent, and the spirit is liberated, purified and sublimated.

This is, there is no neighing of war horses, and there is no glory of warriors, only the white spray of the blue water, which crashes against the rocks, making a moving sound.

A tree, in the long river of years, writes a heroic life: when the wind hits, you refuse to fall; On days when the snow was overwhelming, you refused to give in, and at the moment when the flood raged, you refused to bend down. Standing, the earth is green, standing, giving the river a drop of purity, standing, giving the city a ray of warmth.
