In the English language, a present-tense verb can be changed into a past-tense verb by ensuring that the verb ends with "-ed".
If the verb ends with an "e", then all you need to do is add a "d" to the end. If the verb does not end with an "e", then "ed" must be added to the end of it.
Since waste, smile, share and whistle end with an "e", only a "d" is needed to change them into: wasted, smiled, shared and whistled.
As push, roam, want and appear do not end with an "e", then "ed" is added to change them into: pushed, roamed, wanted and appeared.
To summarize:
waste: wasted
smile: smiled
push: pushed
roam: roamed
want: wanted
share: shared
whistle: whistled
appear:appeared
