Rain and storm always comes with typhoon.
always指得是百分百，如果十次中有八九次一样，不能说always，只能说almost always。
He is always asking questions.
他常提问。
You are always finding fault with me.
你老找我茬，真烦。
She always dreams of him.
两句都指“她老梦到他”，但前者是她未必时常梦到他，而后者是她时常梦到她。
She never laughs.(NOT She always does not laugh.)
Whenever he meets me he always speaks of his father.
句中，whenever已表示任何时候，就不需再加always去强调每次，删掉always或者改whenever成when。
