语篇解读：本文主要讲述了世界卫生组织呼吁开发新的药物，以应对超级病菌对人类健康的威胁。
1．to develop 此处是不定式作目的状语，故填to develop。
2．are 此处表示客观的陈述，故用一般现在时；根据设空前的“These bacteria”可知，应填are。
3．powerful 此处应用形容词作定语修饰名词短语，故填形容词powerful。
4．health 介词后跟名词、代词或动词ing形式作宾语。human health意为“人类健康”，是固定搭配，作介词to的宾语。
5．the ability被不定式短语“to easily turn treatable infections into killers”所修饰，表示特指，故用定冠词the修饰。
6．that/which that/which引导定语从句，在从句中作主语，修饰先行词genetic material。
7．of 固定搭配run out of，意为“用完”，故填介词of。
8．urgently 副词修饰动词、形容词、副词或句子。故此处应用副词urgently修饰动词need。
9．required 分析句子结构可知，require和amount之间为逻辑上的动宾关系，故用过去分词作后置定语。
10．were treated 根据时间状语“at one time”可知，treat所表示的动作发生在过去，且动词treat和infections是被动关系，故用一般过去时的被动语态。
