She said，“The clsest thing t Mars—the stuff—is frm vlcanes mstly.”
“Mars Day” ffered Allisn and Alycia’s children a chance t learn mre abut a wrld that they are very likely t set ft n within their lifetimes.

36. watching考查非谓语动词。watch与he之间是主动关系，故填现在分词作状语。

38. with考查介词。根据空后面的现在分词 grwing可知，此处应该填With，构成with的复合结构。此题很容易受翻译影响而填as，意为“随着”，但是as引导的是时间状语从句，从句中应有相应的谓语动词。
39. t prtect考查非谓语动词。take actin t d sth.采取行动做某事。
40. decisin考査词性转换。所填词前有不定冠词，因此应该用单数可数名词。

42. remved考查非谓语动词。fins与 remve之间是被动关系，因此此处应填过去分词，表被动概念。此处为“with+名词+过去分词”结构。
43.tries考查名词单复数。根据空前面的a few可知，此处需要填可数名词复数。
44. has fcused考查动词的时态。根据时间状语 Since then可知，此处应该用现在完成时。
45. up考查固定短语。grw up是固定短语，意为“长大”。
