Li Qi almost forgot that this Qianqiu Elementary School is a mix and match, forming a large class from the first grade to the fifth grade! If you give a lecture like this, you will definitely not understand it in the first and second grades! It's no wonder that the answer is sparse!

"Uh-huh! It seems that many students don't understand! In this way, there will be no more theoretical stuff to talk about! Is it good for us to get to know the real thing? "Li Qi has a bit of a feeling about the cow playing the piano at this time!

Now the children are happy! Li Qi walked out of the classroom with the bear children!

"Let's start at the door, these are two iron trees, the scientific name is cycad! Cycads are very primitive and are known as living fossils! Its trunk is very hard, and it is commonly known as the iron tree! Cycads are dioecious! Because cycads grow very slowly, there is a saying that the iron tree blooms for thousands of years! Plants are an important part of biology!

Plants are producers in the biosphere and support other creatures on Earth, including humans! Such as the vegetables and fruits we eat, etc.! Li Qi took the children to the iron tree at the school gate and said!

Mr. Xia told him that these two iron trees were transplanted here when he went up the mountain, and they haven't grown much taller for decades! The hard, sharp leaves have grown a lot! This also proves that the growth is slow!

A few pines and cypresses! Li Qi looked at it carefully and said, "There are two varieties of these cypress trees, and the three on the left are juniper, also known as juniper cypress, which is an evergreen tree. Juniper likes shade and is cold-tolerant, drought-tolerant, and does not have high requirements for soil. The young trees of juniper are cone-shaped, with beautiful tree shapes, and the old trees have different postures. In our country, juniper is often used as a traditional garden ornamental tree. This is also the purpose of planting in front of the school! ”

After speaking, Li Qi turned to the right and said to the other cypresses: "This is another variety, called arborvitae, and it is an evergreen tree. His bark, roots, leaves, and seeds can all be used in medicine. In traditional Chinese medicine, there are arborvitae leaves and arborvitae charcoal, which can cool blood and stop bleeding, and are commonly used by people with hemorrhage, such as hemorrhoids!

The wood of Arborvitae orientalis has aroma, corrosion resistance, long life, can absorb dust, absorb harmful gases such as sulfur dioxide, and is an excellent landscaping tree species! It can be seen that Mr. Xia has worked hard for the physical and mental health of his students! ”

"Dr. Li is overrated, I just think it's good-looking, and it's evergreen all year round! I really didn't think about it so much! Today, you only know that there are such benefits! You go on! I've benefited a lot, hehe! Teacher Xia smiled and said modestly.

"I'm really a class axe! Just share some of what you know with your kids! Speaking of which, let me digress a bit! Li Qi didn't blush at all, and turned to the children.

"Students, your current study is like preparing ammunition before a soldier goes to battle! Only when you are well prepared can you win the battle and become a person who contributes to society! So study hard now! You know? "Li Qi is speaking from the heart! If the foundation is not laid, there will be thousands of high-rise buildings there!

"Li Qi! If you don't become a people's teacher, it's a loss to our education community! Either way, this biology class was wonderful! Some children may not understand, but it doesn't affect this vivid lesson at all! At least I asked myself if I couldn't! Because you didn't take your textbook and didn't prepare for class! I'm quite impressed! "Teacher Liu has a feeling!

"Teacher Liu, I don't have a surname award! I still know how many catties I have! Now it's no problem for me to go to a physiology class! Because of the professional relationship! Any other course is going to be blind! "Li Qi is really a little embarrassed!

"Uncle Li! Don't be modest! If you want me to talk about it, I really can't say it! Even if you know it in your heart, you can't express it well! Liao Wei listened to what Li Qi said, and he had learned all of this! But knowing doesn't mean being able to say it smoothly!

"Huh! It's nothing, just exercise more! Just like learning spoken English, you have to read it out loud! Well! Without further ado, let's move on to class! Li Qi smiled and said.

There is a ginkgo tree in the middle of the cypress tree, Li Qi came to the ginkgo tree, this ginkgo tree is taller than this Qianqiu Primary School! I really don't know how many years? It should be even older than this house!

"It's called ginkgo, and it's the oldest relict species of seed plant in existence, and it existed on Earth more than 200 million years ago! It is called a living fossil of words! People call it the Gongsun tree, which means that the grandfather planted it, and the grandson can enjoy the fruit! It's so slow that you can't help but get old! Its fruit is also a seed, named ginkgo seed, named because of its white hard shell!

Ginkgo seeds are flavored traditional Chinese medicine, which can dissolve phlegm, relieve cough and asthma! Such as pediatric external cough, pediatric bronchitis, and long-term cough will be used!

Mr. Xia, did you transplant this ginkgo tree as well? Li Qi asked Teacher Xia!

"No, it's not! It originally grew here, and according to the old people in the village, the tree is about 200 years old! Teacher Xia said.

Behind the ginkgo tree is the peach tree!

"Last year, in this door today, the peach blossoms on the human face were red. The face of the person does not know where to go, and the peach blossoms are still smiling in the spring breeze. Everyone must know that this is called the peach tree, which is a deciduous tree with black bark, and is a common fruit tree and ornamental flowering tree. Peach blossoms have high ornamental value and are a common material for literary and artistic creation! Like the poem I just chanted!

The peaches are gorgeous, juicy and delicious! Although it is not as magical as the fairy peach written in Journey to the West, it is also a favorite of children! Peach wood can also be made into a peach wood sword, which can drive away demons and ward off evil spirits in the hands of people with advanced Taoism!

This may be an exaggeration, but peach blossoms, peaches, seeds and bark can all be used in medicine, and that's true! There are peach kernels, and safflower is a common medicine for injuries and gynecology! Peach blossoms, in particular, are said to have beauty benefits!

All right! Now I have a question for you! The question is, do you know that the words, or poems, or articles describe peach blossoms? "Li Qi asked the children a little question!

When it comes to describing peach blossoms, there are really a lot of articles, but the flowers are too beautiful and gorgeous! Sassy ink man is deeply in love again! In the long history, it has left a lot of gorgeous chapters with hot tastes! There is even a peach blossom luck! This can only be said that everyone has a love for beauty! There's no need to dig deeper!

Then children, you look at me, I look at you! Soon after, little hands were raised!

"Liao Wei! You're a big brother, just be an example! Tell us about words or poems about peach blossoms! Li Qi pointed at Liao Wei and said.

Liao Wei thought for a while and said: ""The Story of the Peach Blossom Spring" should be the most representative article describing peach blossoms!"

"That's right! Recite it for the kids to listen to! Li Qi said a little narrowly.

"The Story of the Peach Blossom Spring"

In the Jin Dynasty, the Wuling people fished for their business. Walk around the river, forget the distance of the road. Suddenly, the peach blossom forest, hundreds of steps between the shore, there are no miscellaneous trees in it, the fragrant grass is delicious, the fallen flowers are colorful, and the fishermen are very different. Moving forward again, I want to exhaust the forest.

When the forest runs out of water, there will be a mountain, and the mountain has a small mouth, as if there is light. Drop off the boat and enter from the mouth. At the beginning, it is extremely narrow, and only then can it be passed. After dozens of steps, it suddenly became clear. The land is flat, the houses are like that, and there are good fields and beautiful ponds and mulberry bamboos. Qianmo traffic, chickens and dogs smell each other. Among them, the men and women are dressed like outsiders. Yellow hair hangs down and is happy.

When he saw the fisherman, he was shocked and asked where he had come from. Answered. Then he had to return home, and set up wine to kill chickens for food. When the village heard about this person, Xian came to inquire. Since Yun Xianshi avoided the chaos of the Qin Dynasty, he led his wife and people to this desperate situation, and did not come back, so he was separated from outsiders. Ask what the world is today, but I don't know if there is a Han, regardless of Wei and Jin. This person sighed for what he had said and heard. The rest of the people returned to their homes, and they all drank and ate. Stop for a few days and resign. The Chinese said: "It is not enough for outsiders." (Interval 1: Isolation)

Once he went out and got his boat, he helped him to the road, and he was determined everywhere. And the county, Yi Taishou, said so. Taishou immediately sent people to follow him, looking for what he wanted, and then he got lost and lost his way.

Nanyang Liu Ziji, a noble scholar, heard it, and happily went to it. Unsuccessfully, the search for the disease ended, and then there was no concern.
