uninterestinginterest—interesting—interestinglyinterested—uninterested由help可以派生出：

helpless—helplesslyhelp—helpful—helpfully由able可以派生出：

enableableunableabilitydisable3.转化法英语构词法中把一种词性转化为另一种词性而词形不变的方法称作转化法。常见的转化有：(1)动词转化为名词

—Let’stalkaboutitmore.

咱们再谈谈这件事吧。

—Ithinkwe’dbetterfinishthetalk

now.我想我们最好现在结束谈话。(2)名词转化为动词

Shegavemeacupofwater.

她给了我一杯水。

Youshouldwatertheflowerstwiceaday.

你应该每天给这些花浇两次水。(3)形容词转化为名词
