Reporting verbs

2.1 VERBS USED WITH "that" CLAUSES

This kind of reported clause is often called a "that" clause, even though many clauses may in informal usage occur without "that". Here is a list of verbs which are often used as reporting verbs with "that" clauses:

*verbs, such as "find" and "know", which can also he used with a "to"-infinitive clause.
 

2.2 PASSIVES OF that REPORTING VERBS

If you want to say what has been claimed, thought, or discovered either by previous researchers or in your own study, you can use "it" as an impersonal "dummy" subject of the passive form of a reporting verb, followed by a "that" clause. This form is most common in non-integral citations.

The major advantage of using a passive structure with "it" ” is that it allows you to avoid having a long or “top-heavy” subject, and thus also allows you to put what you are talking about in a more prominent position at the end of the sentence.

2.3 OBJECTS WITH REPORTING VERBS

Some reporting verbs can have as their objects nouns that refer to events or facts. These nouns are often closely related to verbs. For example, the noun "loss" is closely related to the verb "lose", and instead of saying "He admitted that he had lost his passport", you can say "He admitted the loss of his passport".
