I tried to pass an exam at www.newschool.co.uk site. One of the questions was to choose correct variant among phrases:
A: I just can’t get used to cycle on the left-hand side of the road!
B: I just can’t used to cycle on the left-hand side of the road!
C: I just can’t get used to cycling on the left-hand side of the road!
D: I don’t get used to cycling on the left-hand side of the road!
I choosed A but the site said that the correct variant was C. In school I was taught that the gerund (-ing) cannot be used with the particle 'to", while infinitive needs it. Have the grammar rules changed in the last 40 years?
