Recently we have little time to keep close contact with nature. We spend too much time on study or working. We almost forget that how green the grass is how beautiful the flowers are and how sweetly the birds are singing outside our windows. A saying goes "All work and no play makes Jack a dull boy". It means that we need to relax ourselves and go out to breathe more fresh air. We can also climb a hill in the suburbs.It's good for our health.
Let's go outing.
