2.57 adjectives followed by 'that'-clauses

When adjectives which refer to someone's beliefs or feelings are used predicatively, they are often followed by a 'that'-clause (see paragraphs 7.85 to 7.87). The subject of the 'that'-clause is not always the same as the subject of the main clause, and so you need to specify it.

• She was sure that he meant it.
• He was frightened that something terrible might be said.
• I'm aware that I reached a rather large audience through the book.

Note that the word 'that' is not always used in a 'that'-clause.

• They were sure she had been born in the city.

Here is a list of common adjectives often followed by a 'that'-clause:

• afraid, angry, anxious, aware, careful, certain, frightened, glad, happy, pleased, proud, sad, sorry, sure, surprised, unaware, upset, worried

Note that all of these adjectives except 'angry', 'aware', 'unaware', 'upset', and 'worried' can also be followed by a 'to'-infinitive clause.

• I was afraid that she might not be able to bear the strain.
• Don't be afraid to ask questions.
• She was surprised that I knew about it.
• The twins were very surprised to see Ralph.
