小题5:the
小题6:where
小题7:is called
小题8:find
小题9:determined

题目分析：
小题1:have dreamed。考查动词时态。根据ever since 判断本句用现在完成时，再根据主谓一致的原则可知答案填have dreamed。
小题2:taking 。考查非谓语动词。介词后面跟名词，代词或者动名词，故答案填taking。
小题3:. was 。考查动词。由结构可知此处是强调句型：it is /was +被强调部分+that，根据语境可知此处是过去时，故答案填was。
小题4:that \who 。考查强调句型。强调句型的构成形式是：it is /was +被强调部分+that，如果被强调部分是人，that还可以用who替换，故答案填that或者who。
小题5:the。考查冠词。此处是表示河流的专有名词 the Mekong River，故答案填the。
小题6:where 。考查连接代词。From后面是宾语从句，从句是主谓结构，缺少副词，根据句意可知填where。
小题7:is called。考查谓语动词。此处是定语从句，从句中缺少谓语动词，根据句意可知河流是被称作湄公河，应该用被动结构，填is called。
小题8:find 。考查动词。Insist在此句中的意思是“坚持要求”的时候后面的宾语从句用虚拟语气，谓语动词是（should）+动词原形，故答案填find。
小题9:determined。考查形容词。修饰名词look应该用形容词，根据提示，可知填determined。
小题10:in。考查介词。根据上文意思可知“I”不得不听从姐姐的提议，固定短语：give in“屈服，让步”，答案填in。
