【解析】

文章介绍了美国研究人员正在研究某种消除记忆的药物，这引起了人们的广泛讨论。

【1】their 句意：一些人用一生来忘记不好的经历。修饰名词lives要用形容词性物主代词，因此填their。

【2】which 句意：现在美国研究者正在开发一种药，这能帮人们忘记不好的记忆。which引导非限制性定语从句。

【3】frightening 修饰名词experience用形容词，experience可以看作物，因此用frightening来修饰。a frightening experience一次令人害怕的经历。

【4】discussion a lot of修饰名词，discuss的名词形式是discussion，discussion表示“议论、争辩”时是不可数名词。

【5】sufferings 句意：药片能帮助减少痛苦。根据修饰词many可知，要用suffering的复数形式。

【6】who 先行词是those，指人并在定语从句中作主语，要用who来引导，不能用that。

【7】is 句意：改变记忆是很危险的。动名词作主语，谓语动词用第三人称单数。

【8】Although/Though 句意：虽然药物首先在严重的情况下才能运用，但许多人害怕这会变得普遍。

【9】to use 短语have the ability to do表示“有能力做某事”。

【10】better 句意：我们所能做的是帮助人们更好地控制记忆。
