Hi there, question 1: in this situation 'get at it', the 'it' refers to sexual intercourse/kissing/ other 'sexy' stuff. question 2: I would say 'out of' because it is referring to a database and we can not take things 'off' a data base' (you can however, have your name cleared 'off' a list. furthermore, I would say 'police database', you do not need to indicate possession in this case. question 3: Either say "such a high expenditure...." or "high expenditure" is 'bound to do serious damage' or 'is bound to badly hurt' I hope this helped, feel free to ask for more clarification.
