[Grammar] It's natural that he should marry her.

[chance22]

According to some reference book, "It's natural that ..." is also categorized into subjunctive mood sentence pattern, so what follows should be something like "...(that) someone should do sth." For example,
It's natural that he should marry her.
It's natural that she should do so.
My question is: Should we always use should in the sub-clause like a fixed sentence pattern? Are there conditions for us to use different tenses to state a fact as it is??
e.g. It's natural that he finally married her.
It's natural that she did so.

A reference book published in China as a guide for test takers.

What is its name and author? Say "author unknown" if the book doesn't say who wrote it.

Even if you can't find the name of the author, you must give us the title of the book.

Here's my answer:

Yes, there are conditions where using should is not required, and a normal indicative clause can follow. (It's natural that he marries her.)

However, in sentences without it, there is a lack of mood that would normally be given by using should or a similar subjunctive mood form (It's natural that he marry her), and this lack of mood means that there is a difference in meaning/use.

Then would you please tell me what kind of difference there is in meaning?

 

[jutfrank]

The kind of difference is mood. As you mention in your OP, the type of mood is subjunctive. You can find lots of in-depth explanations about the use and meaning of the subjunctive online.
