（
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(wèn)詞+不定式”結(jié)構(gòu)。句意：她還沒(méi)決定給她爸爸的生日買什么?！耙蓡?wèn)詞+不定式”結(jié)構(gòu)可作賓語(yǔ)，A選項(xiàng)“what to buy”符合語(yǔ)法；B選項(xiàng)“what she buys”是賓語(yǔ)從句，時(shí)態(tài)應(yīng)為一般將來(lái)時(shí)（what she will buy）；C選項(xiàng)“what buying”形式錯(cuò)誤；D選項(xiàng)“what does she buy”是疑問(wèn)句語(yǔ)序，賓語(yǔ)從句應(yīng)用陳述句語(yǔ)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(yǔ)，若不接賓語(yǔ)常用“what to do”，此處“下一步”作狀語(yǔ)，兩種表達(dá)均可，故填They don't know how to do next. 或 They don't know what to do next.
