Would

I would love to live in Hangzhou or Suzhou,but the price of house is so high. 

Those musics helped me live through these hard times,I don't know what I would have done without those musics. Whenever I feel bad,I would listen some musics or used to run. 

I should do something healthy.

You had better not smoke on hospital.

It's time for us to have lunch. 

The lunch is not papering well.But It's about time they cooked some food.

It's essential that one people should find the valuable lifestyle.

Should the situation changes,I will contact you.
