说起来容易做起来难的英文句式介绍如下：
It is easier said than done.
be动词is后面应该用形容词easy的比较级 easier, 因为后面有比较的词than,是把said和done在作比较, than后面省略了it is. 完整的是 It is easier said than it is done.
用done是因为用过去分词(do的过去分词是done)表示被动, 和前面的said同理, 因为事情是被人们说和做的, 所以用done. sth is done by sb, 事情被人做。
easier：英/ˈiːzɪə/ 美/ˈiziər/。
adv.
小心;轻点;慢些。
adj.
容易的;轻易的;舒适的;安逸的;安心的;不费力的;易受攻击的;容易吃亏的;无自卫能力的。
easy的比较级。
