    一般現(xiàn)在時與現(xiàn)在進行時
    一般現(xiàn)在時表示一般的動作或不斷重復(fù)發(fā)生的動作；現(xiàn)在進行時表示說話時正在發(fā)生的動作，動作還沒有完成。簡單圖示如下：
    一般現(xiàn)在時表示永久的情況；進行時表示暫時的情況。
    進行時只用于表示動作或偶爾發(fā)生的事件（We are eating, it is raining等等）。有些動詞（如 like, want, know等）不是動作動詞，因此不能用進行時態(tài)，如不能說 I am knowing或We are liking，而只能說 I know或 We like。
    一般現(xiàn)在時表達某個習(xí)慣性動作，通常與時間頻度副詞連用，如 usually, always, often, sometimes, never等；現(xiàn)在進行時表示此時此刻正在進行的動作，一般與 now, at the moment, today, this afternoon, this evening, tonight等連用。
    We usually watch television at night. But we are listening to the stereo tonight.
