Question

—Can you tell me________ ?

—As long as two months.

A.how soon a battery will last B.how long will a battery last

C.how often you should change a battery D.how long a battery will last

Answer

D

【解析】

句意：——你可以告诉我电池将持续多久吗？——长达两个月。

考查宾语从句的用法。how soon a battery will last此处强调时长，不应用how soon 提问，表达错误；how long will a battery last电池能用多久，疑问语序；how often you should change a battery你应该多久换一次电池，陈述语序，对频率提问；how long a battery will last电池能用多久，陈述语序，对时长提问。分析句子可知，此处是宾语从句，需用陈述语序，排除B；又根据答语“As long as two months.”可知，此处是对时长提问，不应对频率提问。故选D。
