解析：
【小题1】achievement 前面有“a great”修饰，所以这儿要填名词的单数形式。
【小题2】independent 形容词做表语。
【小题3】explanation前面有“a clear”修饰，所以这儿要填名词的单数形式。
【小题4】failure前面有“a ”修饰，所以这儿要填名词的单数形式。
【小题5】fluently 修饰动词“speak”应该用副词形式。
【小题6】embarrassed “感到尴尬”是人的心理感受，要用过去分词。
【小题7】skipped 上文时间状语从句中的谓语动词用的是一般过去时，主句中谓语动词也用一般过去时。
【小题8】challenging前面有“a bit”为副词修饰作表语的现在分词。
【小题9】positions 前面有“one of”说明不止一件，因而要填名词的复数形式。
【小题10】concentration 跟前面“patience”并列，也用名词形式。
