Complete the following sentence

Complete the following sentence with a (compound) word derived from the one(s) given in bracket.
（ ） actions often result in disaster. (ill, consider)

本题考查的是常见单词的复合形容词。

由actions可知，空缺处应填形容词修饰名词，consider为动词，故与ill构成复合形容词时需加-ed，ill-considered意为“不充分考虑的，不妥当的”。

句意：贸然的行动通常会导致灾难。
