1.B
try和sit是同时发生的动作,而且都是主语my sister主动发出的；
所以单用trying做伴随状语就足矣.
having tried表明try/sit两动作有先后关系,句意并非如此.
2.C
固定短语：imagine（sb/one's）doing sth
同上,此句两动作也并无先后,所以单用being
3.B
不定式用逗号隔开并凡在句尾,表明是做结果状语,而且是出乎意料的结果.然而根据句意,并非如此,而是表示伴随动作；
stop也是主语he主动的动作,所以用现在分词,stop和write无先后关系,所以单用stopping即可.
4.D
此题we had ( ) home in the snowstorm是定语从句,修饰先行词what difficulty,关系代词which/that已被省略.
即定语从句完整为：we had what difficulty ( ) home in the snowstorm
楼主可能知道一个固定句型：
sb have difficulty (in) doing sth “某人做某事有困难”（in可以省略）
所以答案就选D walking
5.D
fail在此句做状语,不可能用原形,排除A；
不定式在句首时,只能做目的状语,和句意不符,排除C；
fail和句子主语we我们之间是主动的关系,不能用过去分词,排除B；
D having failed是现在分词failing的完成形式,它一则表主动,二则表发生主句动作sent之前,正好符合句意和语法要求.
