The simple difference between the present and past tense is that the present tense refers to what is happening now, whereas a past tense refers to what happened in the past. 简单来说simple present tense和simple past tense的关系就是同一个动词随着时态变化而变化。 be动词： 原型-过去式 am-was is-was are-were 动词： 原型-过去式 teach-taught love-loved eat-ate go-went 举例如下: I was 15 last year. 去年我15岁。 I am 15. 我15岁。 It was cold yesterday. 昨天很冷。 It is cold today. 今天很冷。 We were friends. 我们曾经是朋友。 We are friends. 我们是朋友。 I taught at Westview High School. 我曾在xx高中教书。 I teach at Westview High School. 我在xx高中教书。 I loved him. 我曾爱过他。 I love him. 我爱他。 I ate 2 oranges. 我吃了2个橘子。 I eat 2 oranges every day. 我每天都吃2个橘子。 I went to the library yesterday. 昨天我去了图书馆。 I go to the library on Saturdays. 每周日我都去图书馆。 |
