(2)She iscomplaining allthe time.(表厌烦)She complainsabout theterrible weather.(说明事实)
(3)r malways seeinghim in the library.(表惊奇)I alwayssee himin thelibrary.(说明事实)
3.在条件或时间状语从句中,将来的动作须用一般现在时表示将来的意义
(1)If youcome tothe party,you11enjoy yourself.
(2)If itrains tomorrow,the sportsmeet will be putoff.
(3)As soonas Iarrive inShanghai,I11call mymother.
4.以here,there等开头的句子,说明动作正在发生时,谓语动词不用现在进行时,而用一般现在时
(1)Here comesthe bus.
(2)There goesthe bell.过去进行时一般过去时vs
1.过去进行时常常表示动作的未完成性,而一般过去时常常表示动作已经完成
(1)My sisterwas readinga bookthis timelast night.(读了一些)My sisterread abook last night.(读完了整本书)
(2)They werebuilding a bridge over the river.(在建造中)They builtabridgeovertheriver.已经建好了
2.过去进行时侧重说明动作的持续时间的长度,而一般过去时只是说明过去某时发生了某事,强调动作的事实
(1)His brotherwas playinggames allnight.(强调整晚都在玩游戏)His brotherplayed gameslast night.(强调昨晚玩了游戏,并不强调持续多长时间)
(2)He wasstudying forthe testthe wholenight.强调整晚一直在备考He openedthe doorand rushedout ofthe room.强调开门和冲出去的动作现在完成时一般过去时VS
1.二者都表示过去发生的动作或情况但是现在完成时强调的是动作的结果,它必然和“现在的情况”有联系而一般过去时只是表示过去的事情,与现在没有联系1I have seen the film with my friends.(说明现在已经了解电影的内容)I sawthefilmwithmyfriends lastweekend.只说明上周末看过了电影2He has been to Beijing manytimes.说明已经去过北京多次He wentto Beijing.(只强调“去过”北京这个动作)3These studentshave studied English for six years.(说明到目前为止学了6年英语)These studentsstudiedEnglishforsixyears.说明过去学过6年英语,现在没学了
2.现在完成时说明目前的情况,所以它属于现在时态的范畴,因此不能和表示确定的过去时间状语连用,如yesterday,last night,the day before yesterday,last year等它只能与不表示明确时间段内状语连用,如already,never,ever,since1949,for threemonths等1I vehad this bike forfive years.I boughtthisbikefive years ago.2Bill hasnt finishedreading thebook upto now.Bill didnt finishreading thebook yesterday.3She hasalready beento ascience museum.She wentto ascience museumlast summervacation.练习:
