💡 ‘Naturally’ at the start of a sentence means ‘as you would expect’, introducing a general observation. ‘Gradually’ describes slow change over time and cannot introduce a general statement. ‘Of course’ is used to agree with or confirm something already stated, not to introduce a new general observation.

💡 ‘Eventually’ means after a long time, something finally happens — matching the specific two-month timeframe. ‘Gradually’ means in slow steps, but ‘little by little’ is not stated here, making ‘eventually’ the better fit for a defined endpoint. ‘Immediately’ contradicts the delay implied by ‘at first’.

💡 ‘Settle in’ means to feel comfortable and at ease in a new place or job, matching ‘stop feeling like a stranger’. ‘Get used to’ requires a noun or -ing form after it and cannot be used alone at the end of a clause. ‘Adjust’ means to make a specific change and does not carry the sense of belonging implied by ‘stop feeling like a stranger’.

💡 ‘Get used to’ followed by a noun means to become familiar with something through experience. ‘Settle in’ cannot be followed by a direct object noun. ‘Come naturally to’ means innate talent from the start, not gradual adaptation over time.

💡 ‘Come naturally’ means to be easy from the start without effort, reinforced by the fact that even months of practice have not helped. ‘Feel natural’ describes comfort achieved after adjustment, which contradicts ‘even after months of practice’. ‘Settle in’ needs a place or job as context. ‘Get used to’ needs an object after it.

💡 ‘Commute’ is the regular daily journey to work. ‘Trip’ is a single non-repeated journey. ‘Travel’ is a general uncountable activity and cannot follow ‘his morning’. ‘Route’ is the path, not the journey itself.

💡 ‘Eventually’ means after a long time, something finally happens — directly matching the defined endpoint of ‘after about two months’. ‘Gradually’ means in slow steps and focuses on the process, not the endpoint; it cannot be followed by a specific time reference like ‘after two months’. ‘Finally’ implies impatience or relief after difficulty, which changes the neutral tone. ‘Immediately’ contradicts the delay.
