C1 Grammar Tests

C1 is advanced level. You can understand long, difficult texts, speak fluently without searching for words, and write clear, well-organised English. You still make small mistakes, but they rarely stop people understanding you.

A gerund is the -ing form used like a noun: 'I enjoy reading.' An infinitive uses to + verb: 'I want to read.' Some verbs take only one form. A few change meaning: 'I stopped to eat' and 'I stopped eating' are different.

Inversion means the verb or auxiliary comes before the subject, often for emphasis. It follows negative or limiting words: 'Never have I seen such a mess.' 'Not only did she win, but she also broke the record.'
