--- Oh. I never doubt ______ it is worth ______ to buy new houses.

1. A.
   whether; to continue
2. B.
   that; continuing
3. C.
   whether; continuing
4. D.
   that; to continue

Answer 1

B
试题分析：doubt用于肯定句时用whether引导同位语从句；用于否定句时，用that引导。sth. is worth sth/ doing此句型中只能用doing，某事值得做。本句中never表达否定含义，故选B。
考点：固定句式
点评：固定句式的考查也是英语考查的一个重点，熟记这些句式可以减少答题中的分析判断时间，所以平时加强句式记忆也是学好英语的关键环节。
