Question

A cough is usually nothing to worry about unless it lasts for ten days _____

A．instead

B．or more

C．a(chǎn)t most

D．Only

Answer 1

B

試題分析：句意：咳嗽通常沒什么可擔(dān)心的除非一直持續(xù)十天左右。instead 代替；or more 大約，左右，放在數(shù)字之后相當(dāng)于about，但是about常位于數(shù)字之前。at most至多；only僅僅。將四個選項帶入分析語境，B 最佳。
考點: 考查副詞的用法。
