乐观主义

Optimism made him alive through the hard days.

乐观使他在艰难的岁月里活了下来。

The place where optimism most flourishes is the lunatic asylum ---Henry Havelock Ellis,British sexologist, physician, and social reformer.

乐观最为活跃的地方是 疯人院 ---.维洛克.艾斯，英国性学家，医生和社改革家。

We are optimist and realist.

我们是乐观，又是现实。

The man who is a pessimist before forty-eight knows too much; the man who is an optimist after forty-eight knows too little.

未逾四十八岁的悲观，是知道得太多之人；而年逾四十八岁的乐观，是知道得太少之人。
