Shelley is an intense and original lyrical poet in the English language. His poems are full of classical and mythological allusions. His style abounds in personification and metaphor and other figures of speech. He describes vividly what we see and feel， or expressed what passionately moves us. Before he was 18， he had written two romances and published a collection of poems， in which he glorified freedom， exposed tyranny and expressed his sympathy for the oppressed. He wrote and published an anti-religious pamphlet the necessity of atheism， believing that religion was an instrument of oppression. At the time of the English government was applying the threat of capital punishment to suppress the working-class movements and progressive publications， he wrote his first important poem queen Mab. By 1818 Shelley had completed an important work， the revolt of Islam. And the next year was a great year in his literary career because in that year he wrote his famous lyrical drama Prometheus unbound. Shelley’s political lyrics are among the best of their kind in the whole field of European romantic poetry. He was the first poet in Europe who sang for the working class. Shelley’s short poems on nature and love occupy a very important place in his literary career. To him， nature exists as an unseen life of the universe， and his love of nature is almost boundless. I like his ode to the west wind best because it is so beautiful and powerful. It can bring the hope of new life to the people.
