Poems rely heavily on imagery, precise word choice, and metaphor (隐喻), and may take either the form of measures consisting of patterns of stresses or of patterns of different-length syllables. But they don't necessarily make use of rhyme. Poetry appears earlier than other forms of literature；however, one cannot readily tell the characteristics of early poetry. Typically, as a form of literature, poetry makes great use of the forms of the words it uses. That is to say, it focuses on the features of the written or spoken word, rather than on their meaning. The play, or drama, is another classical literary form that has continued to develop over the years. It generally consists chiefly of a dialogue between characters and is usually for theatrical performances rather than for reading. During the eighteenth and nineteenth centuries, opera developed as a combination of poetry, drama, and music. An essay consists of a discussion of a topic from an author's personal point of view. The word “essay” in English is from the French word meaning “attempt”．In this sense, it could be said to mean the author's attempt to make others accept their view. Prose consists of writing that does not stick to any particular formal structures. Prose writing can take beautiful forms, but not because of the forms of words it uses. A novel consists simply of a long story written in prose, yet this form has only developed comparatively recently. Early novels in Europe did not, at the time, count as significant literature, perhaps because “mere” prose writing seemed easy and unimportant. It has become clear, however, that prose writing can provide pleasure for those readers even though it doesn't stick to poetic forms. 语篇解读：本文是一篇说明文。文章主要介绍了诗歌、话剧、散文、小说等文学形式。 1．What does the passage mainly deal with？ A．The writing of poems.
