2, "Bai Di's words in the clouds, a thousand miles in Jiangling one day. The apes on both sides of the strait can't stop crying, and the canoe has passed Chung Shan Man. " (The Early Development of Baidicheng by Li Bai in Tang Dynasty)
Analysis: The first two poems literally mean that the poet has to go back and forth to Jiangling in one day, that is, it takes 12 hours (1000 km = 1000 km) to travel 2000 miles. According to this, roughly calculate the ship speed: v = s/t = 1000 km/12 hours ≈ 83.33 km/h. The speed of modern inland steamboat is only 10 ~ 2 1.6km/h, which is too fast for Li Bai. In fact, this is an expression of the poet's eagerness to return.
3. "When my boat was sailing in the fog, the day was getting dark and old memories began. How vast the world is, how close the trees are to heaven, and how close the moon is to the water! . "(Meng Haoran's Sleeping at Jiande in the Tang Dynasty)
Analysis: The poet is still enjoying the night scene in the hotel with great interest. The water in Jiande River is so clear and calm. The poet takes water as a mirror, and the bright moon seems close at hand, so he can sit back and relax tonight. It is clearly a "flat mirror" that makes the bright moon in the sky "image" in the water.
4. Wen Tianxiang, a national hero of the Southern Song Dynasty, once vowed by the Yangtze River that "my heart is a magnet, not the south." . Here, the author uses the magnetic needle stone to compare his determination to resist gold.
Analysis: One of the properties of magnets refers to the north and south, so Wen Tianxiang used the property of "magnetic needle stone refers to the north and south" to compare his determination to resist gold. This makes people involuntarily think of Wen Tianxiang's famous sentence "Who has never died since ancient times, keep the heart of Dan and follow the history". Today's people are encouraged, and their feelings with the ancients are deafening, which inspires their deep patriotic feelings.
5, the fragrance of flowers is warm at first sight, the sound of singing through the trees is happy, and the sun is shining. "These are two poems written by Lu You, a poet in the Southern Song Dynasty, in Happy Village. From the physical point of view, the first sentence can be understood as: the aromatic oil molecules secreted by flowers accelerated, indicating that the surrounding temperature was sudden at that time.
Analysis: The poet expressed his admiration for the beautiful nature with a beautiful style and accurately described the details in the process of seasonal alternation. "The fragrance of flowers attacks people" shows that the poet has already felt the fragrance of flowers without touching them, which is caused by the irregular movement (diffusion) of aromatic oil molecules secreted by flowers; When the temperature around you suddenly rises, you will feel "sudden warmth".
6. The small bamboo raft is in the middle reaches of the river, walking on both sides of the towering green hills. "These two lyrics have long been deeply rooted in the hearts of the people with the famous movie" Sparkling Red Star ". Please use your knowledge of physics to analyze these phenomena.
Analysis: "Walking" and "swimming" represent two different movements, which are called mechanical movements in physics. Whether the "swimming" of bamboo rafts in the river depends on the ground or the green hills on the ground; "Walking" on both sides of "Castle Peak" is actually an anthropomorphic statement. People are standing on the "bamboo raft". If the bamboo raft is used as a reference, then the green hills are moving!
7. Hold the moon in your hand and let the fragrance of flowers permeate your clothes.
Physical knowledge:
"Holding the moon in the hand" is a mirror reflection phenomenon.
"Clothes are full of flowers" is a phenomenon of molecular diffusion.
8. Rizhao incense burner produces purple smoke. Looking at the waterfall hanging in Qianchuan from a distance, I went straight down to thousands of feet. Suspected that the Milky Way had fallen for nine days.
Physical knowledge: the kinetic energy of "flying water" is increasing, while the gravitational potential energy of water is decreasing.
9, the peaks reflect the mountains, no mountains, no water, no ecstasy.
Physical knowledge: reflection and refraction of light
10, peach blossoms set each other off in red
Physical knowledge: The red light reflected by peach blossoms is the decisive factor for the color of objects.
1 1, you can tell a person by his voice.
Physical knowledge: timbre, one of the three characteristics of music.
12, a poem by Li Yi, a poet in the Tang Dynasty, is called "Happy to see my brother goodbye", which describes: "After these ten years of boredom, we meet again. We have all changed a lot. The first time I heard your last name, I thought you were a stranger. Then I heard your name, and I remembered your young face. As can be seen from "Ask the surname", there is a feature in the voice that reminds the poet of his memory ten years ago. This feature is one of the three major features of music.
I wonder if it's enough?
