（
A
）(1)She hasn't decided ______ for her father's birthday.
A. what to buy
B. what she buys
C. what buying
D. what does she buy
答案：A
解析：考查“疑問詞+不定式”結構。句意：她還沒決定給她爸爸的生日買什么。“疑問詞+不定式”結構可作賓語，A選項“what to buy”符合語法；B選項“what she buys”是賓語從句，時態應為一般將來時（what she will buy）；C選項“what buying”形式錯誤；D選項“what does she buy”是疑問句語序，賓語從句應用陳述句語序。故選A。
(2)他們不知道下一步該如何做。
答案：They don't know how to do next. / They don't know what to do next.
解析：“不知道”是don't know，“下一步該如何做”可用“how to do next”或“what to do next”，“how to do”后需接賓語，若不接賓語常用“what to do”，此處“下一步”作狀語，兩種表達均可，故填They don't know how to do next. 或 They don't know what to do next.
