Rule: A noun phrase occurring between the 'Main verb and an infinitive clause object must be the subject of the infinitive.
Examples of errors:
(1) is certain to be misunderstood as 'I asked him if he would copy that article', whereas the intended meaning is 'I asked him if I could copy that article', equivalent to German Ich habe ihm gebeten, diesen Artikel zu kopieren. The author of (1) has correctly applied Rule 3.6, omitting the subject of the infinitive following ask, since it is co-referential with the main subject. This rule alone would have produced the correct sentence:
I asked to copy that article.
= I asked if I could copy that article
The problem is that, following German, he has also failed to remove the indirect object of ask (him). (2) is less likely to be misunderstood, because of the relative incongruity of an inanimate thing (it) being in danger--though a plausible context could be constructed if it referred to a noun like plan, idea, project, etc. Compare:
Bill likes his wife to be the center of attention.
Some people actually like their plans to be in danger, because they like to be challenged.
The one exception to this rule is the verb promise, which allows a following indirect object and omission of the subject of the infinitive:
John promised Mary to be home by midnight.

Here Mary is the indirect object, and John is the omitted subject of be.
