2.Lots of rescue workers were working around the clock,( )supplies to Yushu,Qinghai Province after the earthquake.
A.sending B.to send C.having sent D.to have sent
要说原因，谢谢！！

Answer 1

1，B
解析：as simple as 表示‘与····一样简单’一般结构为as simple as +名词或名词短语，显然这里是用动名词表示，drinking some cold water ‘喝些冷水’所以选B,
2，B
解析：从语义判断，Lots of rescue workers were working around the clock抢救人员在争分夺秒地工作，选B不定式结构表示目的，目的是为了提供帮助；若是A，现在分词做伴随状语，就没这种意思了，就成了强调动作是同时进行的。（而且伴随的动作一般比主句的动作要不重要些，）

Answer 2

B，动名词做主语，喝一点冷水，做后面AS从句的主语
B,援救人员与时间作斗争，是为了输送物资到玉树灾区。表示目的
