B2 First Vocabulary:
Not only…but also
“Not only….but also” requires candidates to use the inverted form of the present tense. It is used to talk about more than one thing which is true, and once candidates understand the grammatical structure they should be able to use it in a variety of questions in both the speaking and writing papers.
The inverted form uses the auxiliary verb before the subject (like when asking a question). For example: “Not only do schools provide children with an education but they also give them an opportunity to develop their social skills”
Below are examples of how 'Not only…but also' could be used in the B2 First (FCE) exam.
