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, try→tried 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 write→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

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.

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:
