问题描述:

The indoor swimming pool seems to be a great deal more luxurious than ( )
A is necessary ;B being necessary ;C to be necessary ;D it is necessary

C

句子的意思
“这个室内游泳池似乎它的奢侈行要比它的实用性大的多。”
1.seem+to do
2.这句是把泳池的实用性和奢侈性做比较,那么应该用并列的时态
seems to be .....than (seems) to be necessary
选C

我手头上有答案,是A.
解释是看别人的:
当比较状语无主语或宾语,连词相当于关系代词.
You spent more money than was intended to be spent.
(关系代词than 在从句中代替先行词money作主语)

The indoor swimming pool seems to be a great deal more luxurious than (C )
结构相同,都用不定式结构。
