题目分析：
小题1:sought。考查动词。根据and前面动词was可以判断句子用一般过去时态，所以此处用seek的过去式sought。
小题2:indeed。考查副词。此处填副词，根据汉语提示可知答案是indeed。
小题3:measuring。考查非谓语动词。分析结构可知前后没有连词所以不是句子，而是独立主格结构，some和动词measure是主动关系， 故用现在分词，填measuring。
小题4:baggage/luggage。考查名词。“行李”是不可数名词，故填baggage或者luggage。
小题5:within。考查介词。表示“在（时间，距离范围）之内”，故答案是within。
小题6:slightly。考查副词。此处是修饰动词，应该用副词形式，所以填slightly。
小题7:violent。考查形容词。 become。是系动词，后面用形容词做表语，故答案是violent。
小题8:unlike。考查介词。 unlike是介词“不像”，所以填unlike。
小题9:puzzles 。考查名词。one of 后面需跟复数名词，根据汉语提示可知答案是puzzles。
小题10:prevents。考查动词。从结构可知此处是非限制性定语从句，从句中缺少谓语动词，根据主谓一致的原则可知答案填prevents。
