I suggest visiting the countryside this weekend for some fresh air and relaxation.

Since the river is too dirty for us to swim in, we should consider going to the pool instead.

How about using public buses instead of motorbikes for a more eco-friendly option?

If we work hard, we are more likely to achieve success.
