请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。注意：每个空格只填1个单词。请将答案写在答题卡上相应题号的横线上。 Literature is a term used to describe written as well as spoken material．Generally speaking, it is often used to describe anything from creative imagination, including works of poetry, drama and fiction． Then why read literature, since it is often imaginary and seems unconnected with real life? A lot of us read literature for pleasure and relaxation．It’s always pleasant to read some interesting books, such as comedies and novels, in our spare time．In a modern life full of pressure, it is our common desire to read some imaginary works and seek relaxation from the stress in life． Reading literature is more than fun; it also enables us to acquire knowledge．As a general rule, literature represents a language or a people, and it often gives us an insight（洞察力）into the traditions, customs, beliefs, attitudes and values of the age in which it was written． Sometimes literature can even offer us new, creative ways to have a better understanding of the world．It helps us make sense of the world around us．It introduces us to new worlds of experiences．We enjoy the comedy and the tragedy of poems, stories and plays; and we may even grow through our literary journey with books．Eventually, we may discover meaning in literature by looking at what the author says and how he/she says it．In a sense, we explore the human condition and analyze how and why people think the way they think and feel the way they feel．Literature enables us to think analytically and promotes open minds．We see the world through the eyes of different cultures and in turn learn the ways to deal with things that happen around． So we can definitely say literature is of great importance to us．Why not get going with one poem, drama or fiction at once?
