Far fewer improvements are made with would at the B2, C1 and C2 levels than what is seen at B1. At the B2 level, for example, learners improve in only one area: their use of would to talk about habitual actions and events in the past.
[talking about a job that the speaker did last year] In my opinion I worked very hard. I would spend a lot of hours at work. (Skills for Life: Entry 1 Chinese)
[from a story about pirates] At night they would go to the rocky seaside and light a fire in order to deceive the boats and let them crash on the rocks. (Cambridge English: First; Portuguese)
The main development at C1 level is seen in learners’ ability to use an increasing range of adverbs with would, including strongly, easily, especially, actually, absolutely and gladly.
Considering the aspects of our education system, and the results of my research, I would strongly recommend the following changes to be made. (Cambridge English: Advanced; Croatian)
Because of her wide and excellent experience with small children I believe that Nascha would easily fit into a family with small children. (Cambridge English: Advanced; German)
The range of adverbs used by learners with would is further increased at the C2 level to include undoubtedly, possibly, normally, personally, eventually, obviously, significantly and inevitably.
[talking about the construction of a leisure centre] I believe that the construction of such a centre would undoubtedly contribute to the improvement of our quality of life. (Cambridge English: Proficiency; Greek)
Organising family-oriented activities would significantly increase membership and raise the society’s popularity with the local community. (Cambridge English: Proficiency; Greek)
So, it is B2 level at which would is mastered, with the final point of learning being in the context of discussing habitual actions. The C1 and C2 levels simply show learner progression on a lexical level. When it comes to progress with would, B1 level is the focal point of development.
