Answer 1

DDAC
1 固定搭配：so+adj+(a) 被修饰的词+that such+(a)+adj+被修饰的词+that
2由句意可知“无论这个电影明星到哪里，总有一群等着看他的影迷”
3do nothing but do have no choice but to do can't but do固定搭配，前有do后无to（do nothing but do和can't but do后用do的愿因，是与前面的状态保持一致
have no choice but to do之所以用to do 是用来为have no choice表目的而用不定式）
4 since有“既然”的意思，“既然你们都知道他，那我就不用向你们介绍他了”由句意只有D符合题意

Answer 2

D： such修饰可数名词 problem可数
D：无论到哪里 根据句意
A：do nothing but do
C：既然 的意思 根据句意
