Among the pleasures in the world, the joy from reading can be one. Happy is the man who ac

quires the 【C1】______ of reading when he is young. He has secured a lifelong 【C2】______ of plea sure, instruction, and 【C3】______ . So long as he has his 【C4】______ books, he need never feel lonely. He always has a pleasant 【C5】______ of leisure moments, 【C6】______ he need never feel 【C7】______ .He is the possessor of wealth more 【C8】______ than gold. Ruskin Calls books "Kings' Treasuries"-- treasuries filled, not 【C9】______ gold and silver and precious stones, but with 【C10】______ much more valuable than these--knowledge, 【C11】______ thoughts, and high ideals. Poor indeed is the men who does not read, and empty is his life.

【C12】______ we choose the right kind of books, reading gives the 【C13】______ kind of pleasure. Some books we read simply for pleasure and 【C14】______ -- for example, good novels. And novels and books of imagination must have their 【C15】______ in everyone's reading. When we are tired, or the brain is weary with 【C16】______ study, it is a recreation to 【C17】______ ourselves in some absorbing story written by a 【C18】______ hand.

But to read nothing but books of fiction is like eating nothing but cakes and sweetmeats. 【C19】______ we need plain, wholesome food for the body, so we must have serious reading for the 【C20】______ . And here we can choose according to our taste.
