presumed innocent . 无论谁被指控犯罪，除非另有证明，否则应被假定为无罪。 【答案】until proven otherwise 【详解】考查状语从句中的省略、动词和副词。对比中英文可知，空处表示“除非另有证明”，可理解为“直到另有证明（犯罪）之前”，可用意为“直到……之前”的从属连词until引导时间状语从句，“证明”可用动词prove，prove和Whoever之间是被动关系，可对从句的主语和be动词同时进行省略，仅保留proven，“另”可用副词otherwise。故填until proven otherwise。

wild，时间状语从句中的主语和主句的主语一致，且从句中有be动词时，可省略从句中的主语和be动词，因此空格处是when returned to the wild，故填when returned to the wild。 50．尽管面临着各种各样的危险，但我相信我们最终会成功。 Though kinds of difficulties, I am confident that we will in

with”；“succeed”意为“成功”，动词词性，在句中作谓语，“will”后接动词原形。故填faced with; succeed。 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $ Unit 1 Nature in the Balance 省略 一、单句语法填空 1．Though (tire) after a long walk, she still insisted
