解析：

1．此句中指出的是：中国人该找到的空间。显然用room，而不是其他实物体名词。 2．journey和trip只作名词，ravel和tour既可作名词．又可作动词；travel是正式的通常概念上的旅行，最后一定要返回出发地；tour侧重到多处观光，强调路线曲折。 3．根据句意，中国人是首次登北极，故用first。 4．选项A、B和D不合句意；announce多强调宣布公众所关心的社会问题。 5．短语a while ago方才，刚才。 6．hold back阻止，抑制；其他搭配均不合句意。 7．which引导非限制性定语从句，关系代同which在从句中作主语。 8．根据句意，此处该用介词during。其他为连词，不合句意。 9．作几个常用词的用法比较：rise（太阳、水、气等的）升起；raise（人为的）升起；lift 举起；carry携带。 10．众所周知的时刻，known as polar day作定语，修饰a time。 11．版图与扩展之间存有主谓关系，故用spreading。 12．work out设计出，作出；pick out挑选；keep out使在外；carry out贯彻，执行。本句句意为：中国在实施着许多研究，目的是想了解更多的北方气候和环境的变化。故选D。 13．根据第12题句意，可知。 14．such as表示列举，for example＝for instance举例说明，such that如此。 15．have something to do with与……有关。 16．选项A、D不合句意；B为不及物动词；故选C。 17．in greater depth意为“在更深层处”．greater强调与此之前的含蓄比较。 18．include强调包含有，而contain表示内含，不用进行时，including为介词。 19．of与抽象名词连用相当于该名词的形容词，即of great support＝very supportable。 20．为 which was established的省略形式。 |
