分词作状语____more than 80,000 people,the Wenchuan erathquake was the worst to strike China since the Tangshan earthquake in 1976.A.Killed B.Killing C.Having killed D.Having been killed为什么选C不选A?
从题干中以及since可以看出此句十一哥完成时态.同时主语是the Wenchuan erathquake,所选择以用having killed 而不是Having been killed 或者A.Killed
关于过去分词作状语可以参考：
一、弄清过去分词作状语的最基本特点,初步认识过去分词作状语
过去分词作状语表示被动的和完成的动作.例如：
Written in a hurry,this article was not so good!
因为写得匆忙,这篇文章不是很好.
析：written 为过去分词作状语,表示这篇文章是被写的,而且已经被写.
值得注意的是,有些过去分词因来源于系表结构,作状语时不表被动而表主动.这样的过去分词及短语常见的有：lost （迷路）； seated （坐）； hidden （躲）； stationed （驻扎）； lost / absorbed in （沉溺于）； born （出身于）； dressed in （穿着）； tired of （厌烦）.
Lost / Absorbed in deep thought,he didn't hear the sound.因为沉溺于思考之中,所以他没听到那个声音.
Born in this beautiful town,he hates to leave it.
出生于这个美丽的小镇,他不愿离开它.
二、明确过去分词作状语时的逻辑主语,进一步认识过去分词作状语
过去分词作状语时其逻辑主语为主句的主语,此时应注意人称一致.例如：
Given another hour,I can also work out this problem.
再给我一个小时,我也能解这道题.
析：given 为过去分词作状语,它的逻辑主语为主句主语 I ,即 I 被再给一个小时.
Seen from the top of the hill,the city looks more beautiful to us.
从山顶看城市,城市显得更漂亮.
析：seen 为过去分词作状语,表“被看”,由语境可知,它的逻辑主语必须是城市,而不是“我们”,因为“我们”应主动看城市.
值得注意的是,如果过去分词作状语时,前面再加逻辑主语,主句的主语就不再是分词的逻辑主语,这种带逻辑主语的过去分词结构实际上属于独立主格结构.例如：
The signal given,the bus started.
信号一发出,汽车就开动了.
析：the signal 是 given 的逻辑主语,因此主句主语 the bus 就不是 given 的逻辑主语.
Her head held high,she went by.
她把头昂得高高地从这儿走了过去.
析：her head 是 held high 的逻辑主语,因此主句主语 she 就不再是 held high 的逻辑主语.
三、弄清过去分词作状语的由来,从宏观上把握过去分词作状语
过去分词作状语来源于状语从句.例如：
Caught in a heavy rain,he was all wet.
因为淋了一场大雨,所以他全身湿透了.
析：caught in a heavy rain 为过去分词短语作原因状语,它来源于原因状语从句 Because he was caught in a heavy rain.
Grown in rich soil,these seeds can grow fast.
如果种在肥沃的土壤里,这些种子能长得很快.
析：grown in rich soil 为过去分词作条件状语,它来源于条件状语从句 If these seeds are grown in rich soil.
值得注意的是,状语从句改成过去分词作状语时有时还可保留连词,构成“连词＋过去分词”结构作状语.
When given a medical examination,you should keep calm.
当你做体格检查时要保持镇定.
四、明确过去分词作状语的位置.
过去分词可放在主句前作句首状语,后面有逗号与主句隔开；也可放在主句后面,前面有逗号与主句隔开.例如：
He stood there silently,moved to tears.= Moved to tears,he stood there silently.
他静静地站在那里,被感动得热泪盈眶.

因为主语是the Wenchuan erathquake 不能用被动

since用完成时
汶川地震是自1976年唐山大地震后对中国创伤最大的地震，已经有80000人死去了
主语是地震，是地震杀了人。Having作伴随
A.Killed 主语是人
