By the time a problem has been addressed and remedied it may have vanished in the marketplace, to be replaced by new abuses of power.(2018年英语二text3)

【句型解析】“By the time a problem has been addressed and remedied”这是时间状语，句子真正的主干是“it may have vanished”，“in the marketplace”做地点状语。

【语法分析】“By the time”是介词短语，常做连词使用，在这里相当于“when”连接时间状语。“and”是并列标志，连接两个并列的动词。“may have done”表推测，注意和“should have done”的区分。“to be replaced by new abuses of power”不定式表将来。

【难点分析】考生容易因分不清句子的主干而读不懂题意，需了解“By the time”在这里相当于“when”连接时间状语，可译为“当……时”。

【翻译】在问题得到解决和纠正时，它可能已在市场中消失，并由新的滥用权力所取代。
