在英语中介词后面允许跟名词性从句构成介词短语吗？

Question

麻烦高手举几个例句，便于理解，不胜感激 ！
介词+名词性从句这样的介词短语结构如果存在，以次类推，是否能像介词+名词这样的介词短语那样能在句子中间充当状语，表语，还有定语成分呢？

Answer 1

不仅可以，而且很常用。构成介宾结构。如：
1.I am think about whether I should go.(这里whether I should go就是宾语从句，做介词about的宾语，组成介宾结构)

2.We should learn from what you have done wrongly.(我们应该从你做错的事中吸取教训)这句的宾语从句what you have done wrongly就是介词from的宾语

3.Whether we go depends on what you'll say.(我们去不去取决于你怎么说)这句的宾语从句what you'll say就是介词on的宾语。

Answer 2

1. 允许.

2. 如：
1）I always walk to school except when it rains.
2）The house is well designed except that it's door is too small.
3) The question lies in that he is too lazy.
4) Just take a look at what I've brought for you.
5) He always drives his car at what is called a dangerous speed.
