Question

【题目】—Can you make sure?
—Sorry, I can't.
A.when will she arrive
B.whether she will join us or not
C.why she would speak in the meeting
D.where can she have a discussion with me

Answer 1

【答案】B
【解析】句意：—你能确定她是否加入我们。—对不起，我不能。此处作为动词短语make sure的宾语从句，用陈述语序：疑问词+主语+谓语+宾语。故排除AD两项。根据can可知此处用一般现在时或一般将来时，C项是过去将来时，故排除。故选B。
