Please translate the following words in English首先惠特曼的自由诗的表现形式对郭沫若的诗歌产生了深刻的影响。自由诗的形式可以让诗歌更加自由、灵活和多样化不拘泥于传统的诗歌形式让作者更加自由地表达自己的情感和思想。在这四首诗中没有固定的韵律郭沫若在诗歌中自由地表达自己的情感例如在《炉中煤—眷念祖国的情绪》中郭沫若用自由诗的形式表达了对故乡和心爱的人的思念

Firstly, Whitman's free verse had a profound influence on Guo Moruo's poetry. The form of free verse allows for more freedom, flexibility, and diversity in poetry, breaking away from traditional poetic forms and allowing the author to express their emotions and thoughts more freely. In these four poems, there is no fixed rhythm, and Guo Moruo uses free verse to express his emotions, such as in "Coal in the Stove - Emotions of Missing the Motherland," where he expresses his nostalgia for his hometown and loved ones, making the poem more genuine and touching. Furthermore, in "Morning Greetings," Guo Moruo uses various poetic forms, such as interrogative sentences, exclamatory sentences, and declarative sentences, demonstrating his rich and colorful thoughts and emotions. He also employs a relatively free rhythm and tempo, making the poem more smooth and natural.

Secondly, Whitman's use of long lines also influenced Guo Moruo's poetry. The use of long lines allowed Guo Moruo to express his poetic ideas in more detail and richness. He could use long sentences and paragraphs to describe the details and emotional changes of things, making the poetic imagery more profound. For example, in "Tengu," the long sentence "I run, I shout, I burn. I burn like a fierce fire! I shout like the ocean! I run like lightning!" reveals the poet's strong emotions and thoughts, expressing his unwavering pursuit and exploration of the world.

In addition, listing is a common technique in Whitman's poetry, using a series of things to express the poet's understanding and feelings about the world. This technique is widely used in Guo Moruo's poetry, such as in "Tengu," where he lists "I am a Tengu! I swallow the moon, I swallow the sun, I swallow all the planets, I swallow the whole universe. I am myself!" Through listing, Guo Moruo expresses his desire and pursuit for power and control. In "Morning Greetings," Guo Moruo lists many things, such as the sea, sunrise, white clouds, silk rain, sea mountains, Yangtze River, Yellow River, Great Wall, and snowy wilderness, which form a vast space and create a strong visual impact and emotional resonance, allowing readers to feel the author's emotions. In the poem "Standing on the Edge of the Earth and Sounding the Horn," phrases like "countless white clouds," "magnificent clear view of the Arctic Ocean," and "infinite Pacific Ocean" are all examples of listing details.

Finally, repetition is also an important form in Whitman's poetry. By repeating key words or phrases, the emotional impact and intensity of the poem are strengthened. This can also be seen throughout Guo Moruo's poetry. For example, in "Coal in the Stove - Emotions of Missing the Motherland," Guo Moruo repeats "my young girl" and "my loved one," making the poem more powerful. In "Morning Greetings," Guo Moruo repeatedly uses the phrase "Morning Greetings!" to emphasize his wishes for things and people all over the world, expressing his love and care for the world and allowing readers to feel the author's emotions. The phrase "Ah! Liyo! Liyo!" in "Standing on the Edge of the Earth and Sounding the Horn" is a repeated key word expressing the author's desire and pursuit for strength, enhancing the expressive power and emotional impact of the poem.

In conclusion, Whitman's techniques such as free verse, long lines, listing, and repetition had a profound influence on Guo Moruo's poetry. These techniques and styles not only made Guo Moruo's poetry more free, unrestrained, and passionate, but also made it more powerful and expressive, better conveying the poet's thoughts and emotions
