PrepositionsB2

Dependent prepositions: depend on, good at

Words that own their prepositions: depend on, accuse of, good at, interested in, married to; preposition + -ing

Learning Goal

I know the dependent prepositions of high-frequency verbs and adjectives, with -ing after them.

Exam Skills:B2 First Use of English

Look at these examples. Can you spot the grammar pattern?

She apologized for being late and blamed the bridge for opening at rush hour.

He's brilliant at chess, terrible at small talk, and married to a poker champion.

He's brilliant at chess, terrible at small talk, and married to a poker champion.

Pay attention to the highlighted parts. What do they have in common?

The preposition belongs to the word, not the meaning:

VerbsAdjectives
depend on, rely ongood/bad at
accuse sb of, dream of/aboutinterested in
apologize for, blame sb forafraid/proud of
insist on, congratulate onmarried/similar to
listen to, wait forfamous for, responsible for

After the preposition a verb takes -ing: good at cooking, insisted on paying, apologized for being late. Learn word + preposition as one unit.
