Question

下面有一般过去时和完成时态,选出完成时态,并填上has 怎么区分啊?）

Answer 1

1.she has just boiled an egg.

2.she boiled it a minute

3.she has never been to vhina,but he was there in 1992

4.he has already painted that bookcase

5.he painted it a week ago

6.she emptied the basket this morning

7.he has just dusted the cupboard

本人脱离学习状态多年,略加解释,一般句子里面有相应动作有时间点的,用一般过去时,而没有时间点,有"just,already"等副词的,用现在完成时.填出上面的句子我现在靠的更多的是传说中的“语感”,多读多练可以培养出来.
