Answer 1

56．taking 考查动名词．dream of 中of为介词，介词后边的名词要加ing变成动名词做介词的宾语．
57．It 考查强调句．本句是一个强调句，被强调部分是WangKun，根据强调句的固定结构It is/was+被强调部分+that+句子的剩余部分，所以答案是It．
58．to 考查动词不定式．根据句意：是王坤第一个有了沿眼湄公河骑自行车旅游的想法．the idea to do是做某事的想法．
59．which 考查定语从句．本句是一个非限制性定语从句，先行词为the Mekong River，在介词短语the souce of 后边用which引导．
60．As 考查连词．根据句意：当湄公河进入东南亚地区时，as是连词"当…时"．
61．difficulties 考查名词．根据句意：尽管有这些困难，王坤和王伟决心开始他们的旅行．difficulty是名词"困难"，通过前文可知这里的困难可不止一个，所以用复数形式．
62．determined 考查固定短语．根据句意：王坤和王伟决心开始他们的旅行．be determined to do sth是英语的固定搭配"决心做某事"．
63．the 考查冠词．根据句意：海报多于5000米的青海省．这里是特指，所以用定冠词the．
64．where 考查定语从句．本句是一个非限制性定语从句，先行词是Yunnan Province，在定语从句中做地点状语，所以用关系副词where来引导．
65．happiness 考查名词．分析句子可知，定冠词the后边要跟名词作主语，本句中要填的是主语，happy是形容词"高兴的"，它的名词是happiness．
