I wonder why the author used the infinitive here. I was taught that after chance we have to use of + the gerund
i.e. you have a chance of improving …
Is it a new language tendency or I got something wrong?
Thank you and have a nice day
Hi LS
In a nutshell, you got something wrong. 
The expression “a/the chance to + infinitive” has been widely used as long as I can remember.
My take on the difference is this:
“a/the chance to + infinitive” - ‘chance’ tends to mean ‘opportunity’.
“a/the chance of + noun/gerund” - ‘chance of’ of tends to be similar in meaning to ‘risk of’ or possibly ‘odds of’.
In other words, “a/the chance to + infinitive” tends to refer to something more likely and/or more positive, and “a/the chance of + noun/gerund” tends to refer to something more negative and/or less likely.
Note that I have used the word “tends”. That’s because I’ve given you tendencies, not absolute guidelines. But I think they are very strong tendencies.

Hi, Yankee
Thank you so much ! That disspells my doubts all right
(actually I was thinking the same thing as you but in my textbook there was only one option with gerund)
Hi lost_soul,
Your question really comes back to the basic difference between the infinitive and the gerund after certain verbs such as ‘like’ as in I like swimming or I like to swim on holiday. This is where the gerund suggests generality and the infinitive indicates specificity.
You can transfer that difference to your example: chance to/chance of. Chance to is more specific as in: If you accept this scholarship, you will have a chance to see the major cities of the world. Chance of is more general as in: As you grow older, you will have the chance of seeing the world.

Though I think the difference is difficult to explain, I don’t think the idea of specific vs. general/not specific works terribly well in this case.

Hi,
I think your examples, Amy, apart perhaps from number three, do point to the idea of generality because the ‘chances’ in all the examples are less ‘positive’ in the direction of reality than would be the case in the use of the infinitive.

Hi Alan and Yankee,
Thank you very much for such a thorough and exhaustive explanation .

Once there was an interesting discussion on CHANCE here also.
