11. 動詞的時態(tài)

11.1 一般現(xiàn)在時的用法

1) 經(jīng)常性或習(xí)慣性的動作，常與表示頻腮度的時間狀語連用。

時間狀語： every…, sometimes,　at…, on Sunday

2) 客觀真理，客觀存在，科學(xué)事實(shí)。

注意：此用法如果出現(xiàn)在賓語從句中，即使主句是過去時，從句謂語也要用一般現(xiàn)在時。

例：Columbus proved that the earth is round..

4) 現(xiàn)在時刻的狀態(tài)、能力、性格、個性。

第一句用一般現(xiàn)在時，用于操作演示或指導(dǎo)說明的示范性動作，表示言行的瞬間動作。再如：Now watch me, I switch on the current and stand back. 第二句中的now是進(jìn)行時的標(biāo)志，表示正在進(jìn)行的動作的客觀狀況，所以后句用一般現(xiàn)在時。
