Exercise This is the 46th day. Because of the preparation for postgraduate examinations, I have to spend much of my time on study. But I know I need to exercise regularly to refresh myself, physically and mentally. Taking a walk is a good choice and now it takes me about an hour to walk along streets everyday. In the days to come, I am likely to exercise in other ways which interest me. I also hope you can develop the habit of exercising on a regular basis. I am grateful to everyone, especially to my family, friends and teachers. Good night.

(Sentence is correct and fine, but I'd suggest that you try and avoid starting sentences with a 'because' clause. In English, we try and avoid this. I'd reverse your order here, 'I have to ...., because ....')
But I know I need to exercise regularly to refresh myself, physically and mentally. Taking a walk is a good choice and now it takes me about an hour to I walk about an hour along some streets everyday ('takes me' is awkward here and doesn't work without making other sentence changes). In the days to come, I am likely to exercise in other ways which interest me. I also hope you can develop the habit of exercising on a regular basis as well.(better with this added).
I am grateful to everyone, especially to my family, friends and teachers.
Good night.
