Answer 1

Several heads of state attended the celebration (marking) the first anniversary of the party.括号里是现在分词作伴随状语 而不是目的状语所以不能用to mark
伴随 即 前面句子意思本身 就意味着marking
There still exist strong disagreements ( ) whether social stability should be maintained at the expense of public health.
A.as to B.in terms of C.concerned D.regarded
答案是A，因为这是根据句子意思 决定的
用于提出问题：as to必须位于句中，前面出现的大都是表达某种心理活动的动词，形容词或名词，其后引接出wh-clause或who-to-v结构，表示“在……的问题上”、“就……问题来讲”
其他选项意思或语法不对

选项B后面应该跟名词短语
选项CD 分词垂悬 故错
