一般过去时的用法
一、概念
表示在的过去某个时间里所发生的动作或存在的状态。通常在句子里找到表示过去时间的词或词组。如:yesterday,yesterday morning,yesterday afternoon,yesterday evening,the day before yesterday(前天),last night,last week,last month,last year,a moment ago(刚才),just now(刚才),two days ago,a week ago,in 1990等。
如:I went to bed at eleven last night. 昨晚我11:00睡觉。
四、动词过去式的构成规律
(一)规则动词的过去式
1.一般情况下,在动词原形后面加-ed;look→looked play→played start→started visit→visited
2.以不发音e结尾的动词,在词尾直接加-d;live→lived use→used
3.以“辅音字母+ y”结尾的动词,先将y 改为i ,再加–ed;study→studied, tr y→t ried fly→flied
4.以重读闭音节(即辅音+元音+辅音)或r音节结尾,末尾只有一个辅音字母的动词,要先双写这个辅音字母后,再加–ed。stop→stopped plan→planned, prefer→preferred
(二)不规则动词的过去式
1.改变动词中的元音;begin→began drink→drank come→came eat→ate grow→grew run→ran know→knew win→won speak→spoke take→took wri te→wrote get→got
2.变词尾的–d 为–t ;build→built lend→lent send→sent spend→spent bend→bent
3.与动词原形一样;cut→cut put→put cost→cost hurt→hurt shut→shut
4.变-ay 为-aid (少数动词);say→said pay→paid lay→laid
5.采用不同词根;sell→sold teach→taught buy→bought
6.其他。am/is→was are→were have/has→had do→did
五、加“-ed”后的读音方法
1.ed加在清辅音后面读/t/。finished /-t/ help /-t/ asked /-t/
2.ed加在浊辅音或元音结尾的,读/d/。played /-d/ lived /-d/ enjoyed /-d/
3.ed加在/t/或/d/后面,读/id/。wanted /-tid/ needed /-did/ visited /-tid/
六、句式变化
(一)一般过去时的一般疑问句
1.把was, were放在句首,其余位置不变。由Was…?引导的一般疑问句,肯定答为:Yes,… was. 否定回答为:No,…. wasn’t. 由Were…?引导的一般疑问句,肯定回答为:Yes,… were. 否定回答为:No,… weren’t.
如:(1)I was born in Shanghai. →Were you born in Shanghai?→Yes, I was. (肯定回答) →No, I wasn’t. (否定回答) (2)They were in Li Yan’s home last night. →Were they in Li Yan’s home last night?
→Yes, they were. (肯定回答) →No, they weren’t. (否定回答)
2.在行为动词的句子中,要用助动词词did来引导,其余的语序不变。要注意的是,要把行为动词的过去式改为原形。肯定回答为:Yes, …did. 否定回答:No, …didn’t.
如:John played computer games last night.→Did John play computer games last night?
→Yes, he did. (肯定回答) →No, he didn’t. (否定回答)
(二)一般过去时的否定句
1.在表示过去存在的状态的句子中,相接在was, were的后面加上not。
如:(1)He was in the park the day before yesterday.→He was not in the park the day before yesterday.
(2)We were busy last week.→We were not busy last week.
2.在表示过去的时间发生的动作的句子中,要在行为动词的前面加助动词didn’t.然后把过去式的行为动词改为动词原形。即:didn’t + 动词原形。
如:(1)She played the violin last night.→She didn’t play the violin last night.
(2)They swam in the lake yesterday.→They didn’t swim in the lake yesterday.
(三)、一般过去式的特殊疑问句
