一般现在时的用法 (1)经常性或习惯性的动作,常与表示频度的时间状语连用。 时间状语:every…,sometimes,at…, on Sunday I leave home for school at 7 every morning. (2)客观真理,客观存在,科学事实。 The earth moves around the sun. Shanghai lies in the east of China. (3)表示格言或警句中。 Pride goes before a fall. 骄者必败。 注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。 例:Columbus proved that the earth is round…… (4)现在时刻的状态、能力、性格、个性。 I don't want so much. Ann Wang writes good English but does not speak well. 比较:Now I put the sugar in the cup. I am doing my homework now. 第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。
