问题补充：

—Wherethe twin , Do you know? —Jurong.

A. do; from

B. does; from

C. is; from

D. do; come from

答案：

A. do; from

B. does; from

(答案→)C. is; from

D. do; come from

解析：句意：这个双胞胎来自哪里，你知道吗？句容。Be from…来自哪里，相当于come from.如果句中有come from，疑问句中用助动词do，例如Where are you from?=Where do you come from?题中主语是the twin是单数，用is，故选C
