Answer 1

1.C.what it is 为正确选项。
这是强调句的疑问句形式，语序：疑问词+is/was+ it +that +其它，宾语从句时语序：疑问词+it is/was+that +其它。

2. C.going 为正确选项。
这是what do you say to （doing）sth 的固定短语，“你对（做）某事有什么意见？”，表示征询别人的看法。这里的to 是介词。

Answer 2

1.When I try to understand_____ that prevents so many Americans from being as happy as one might expect,it seems to me that there are two causes.
答案选C，当我试着去理解，后面接宾语what....由于是宾语，就不能用疑问语序，所以是what it is
2.what do you say，是“你愿不愿意，你的意思是”to going there？你愿不愿意去那儿？
to是连词（介词）

Answer 3

1C 2 C
第一个句子为强调句的特殊疑问句式，
第二个句子中
What do you say to 在这里to是介词
