easy

eas 舒适的；容易的 + y …的 → 安逸的；简单的

除用作形容词外，有时用作副词，主要用于某些习语，如：
Take it easy.不要紧张。
Easy come,easy go.来得容易，去得快。
Easier said than done.说说容易做起来难。
如要表示做某事很容易，通常用：It is easy to do sth这个句型。如：
It?s easy(for me)to answer the question.
要(我)回答这个问题是容易的。
这类句型的主语通常是it，不能是具体的人或事物，除非这个人或物与其后的不定式有动宾关系(且这个不定式必须用主动式表示被动意义)，如：
English is easy to learn.英语易学。
He is easy to work with.他容易相处。
但不能说：He is easy to learn English.

以下这两个形容词均包含”简单的，轻易的”的意思
simple：普通用词，指不复杂、不难懂，从而容易被理解的事物。
easy：普通用词，指不需要花费太多精力的工作或事，在实际运用中常与simple换用。
