ている does not always mean “is doing.” Depending on the verb and context, it can describe an action in progress, a state left by a change, or a repeated activity. First ask what the verb describes, then choose a translation.
Formation and use
With activities such as 読む and 勉強する, ている can show an action underway: 今、本を読んでいます. The time word 今 helps establish the intended reading.
With a change such as 結婚する or ドアが開く, ている commonly describes the resulting state: 結婚しています means being married, and 開いています means being open. It need not describe the change happening now.
Comparisons and common errors
Time and frequency expressions can support a habitual meaning: 毎朝、走っています. Japanese does not force a one-to-one match between the English progressive and this form.
知っています means knowing; its ordinary negative is 知りません, not a mechanical 知っていません. In casual speech い may drop, as in 読んでる, but practise the full form first.
