一道SAT英語語法題
The gong,believed to have originated in Western Asia,reached China in the sixth century,where it continues to be used for a wide range of purposes,（including as） a military signal,a rhythmic accompaniment for vocal performance,and a ritual instrument.
括圈里面是需要替換的部分,其實不用替換這個就是正確的用法,而我選擇的是which include.請英語帝解釋這里問什么要用including as 為什么include要加ing難道沒錯嗎?
一樓，但是正確的答案是不做任何改變，including as 是正確的！
