Question

  Even though they are not doubtful at all _______ John will pass the exam, I still wonder ______ he is fully prepared.

A．whether; that

B．that; whether

C．that; that

D．whether; whether

Answer 1

B

考查同位語從句。boubtful“懷疑的，有疑問的”，用于肯定句時，同位語從句用whether引導；用于否定句時，同位語從句用that引導；wonder“懷疑，想知道”，用whether引導賓語從句。故選B。
