I have used "leisurely in my sentences. Would you please correct my mistakes?
1. Diana always liked to shop leisurely because that was the only time he felt well in town.
2. Dr Philips was popular among his patients because his treated them in a leisurely manner.
3. The couple held hands and strolled leisurely in the sea shallows.
4. A group of noisy students in a dinghy paddled leisurely along the river.
