Question

【題目】After three days' waiting, there was a little doubt in the mother's mind _______ the police could find her lost child.

A. howB. that

C. whereD. whether

Answer 1

【答案】D

【解析】

考查同位語從句。句意為：在等了三天之后，母親的心中產生了點懷疑，警察是否能夠找到她丟失的孩子。whether the police could find her lost child是同位語從句，是對doubt起著補充說明作用。故選D。
