affect(ed)
1.affect作“发生影响于…”解，这影响也许是好的，也许是不好的，但往往指不好的。假使它的宾语是health或指身体某部分的词，那影响总是不好的。如This may affect your health（这个也许将有害于你的健康）和My throat is always affected by bad weather。有时affected的意思不够明确，如The progress of the building has been affected by the storm里用affected不及用hindered, delayed, stopped等明确。
2.affected作“做作、不自然”解，语气比unnatural重。例如：His style is too formal and unnatural, and even affected.
