unit1：一般过去时与现在完成时练习.doc

现在完成时与一般过去时的区别语法归纳专练 现在完成时：表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，不能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。 一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。 ①现在完成时是“have／has＋动词的过去分词”，它强调动作的发生对现在造成的影响或结果，注重现在；一般过去时只表示过去某一时间发生的动作，不关注对现在的影响。 ??? 例如： read the book last year．去年我看过这本书。 ????????? have read the book．我看过这本书。（我现在了解这本书的内容）hey have lived in taiyuan for ten years．他们在太原住了十年了。 ??????? have worked in this factory since1978．自从1978年以来，我一直在这家工厂工作。 如果在句中出现了非延续性动词come，leave，go lose，see，begin，start，arrive，become等，改为完成时的句子时，要用相应的词语来替换。常用的非延续性动词与之相应的延续性动词有：come—be in，arrive—be in，leave—be away，begin—be on，start—be on，become—be，stop—be over ，borrow—keep，buy—have，fall asleep—be asleep，open—be open，close—be closed，join—be in／be a member of，die—be dead，go out—be out，catch a cold—have a cold，come back—he back，put on—be on，fall ill—be ill。 ??? 例如：he came back three days ago. ＝he has been back for three days. ????????? she left home two months ago. ＝she has been away from home for two months. ?练习一般过去时和现在完成时的比较练习 .一般过去时选择填空（一） （last…., yesterday…, ago , just now , in 1980 . once , when …, before… , after… ）(?? )1. a: ________ you _______ the football match yesterday? b: yes, I did. it was great. a. did; see??????? b. have; seen?????? c. will; see?? ???d. were; seen (?? )2. a: ________ you at home yesterday evening? b: yes, I _________ with my mother a. were ; were???? b. was ; was????? c. were ; was??? d. was ; were (?? )3.
