- 试题详情及答案解析
- I never doubt _____ this exhibition is worth ________.
| A．whether, to visit | B．that, to visit |
| C．if, visiting | D．that, visiting |
- 答案：D
- 试题分析：由doubt 引导的宾语从句时，doubt 是肯定形式的话，连词用whether，例如：I doubt ( whether ) this exhibition is worth visiting or not.如果doubt 是否定形式的话，连词用that。本句就是否定形式，表示我觉得不怀疑，那么连词就得是B,that。be worth doing 值得做······。故选D.
考点：考查连词及动名词的用法。
