英语时态：过去时1.he did not leave here yesterday.2.did he leave here yesterday?1.did not+动词原形吗?还是加过去式?2.在疑问句,是did+he+动词原行吗? when he saw the ruler was not following his advice,he resigned.从句为什么用过去进行时?能用一般过去时态吗,哪种时态合适些? 英语Whay did you do today?回答时态Whay did you do today?回答是用：过去时 还是 过去分词 还是 一般现在时 还是 现在进行时? 关于not...anymore第一个句子：He did not play the violin anymore 第二个句子：I am not happy anymore 我想问一下大家为什么第一个系动词是did 第二个系动词是 am 一个是过去时 而一个是现在进行时 时态是 did you go home?为什么did用过去时,go 为什么不用过去时态? 英语过去时态有几种 用do/did表示“确实”的意思时怎么判断人称时态如“他的确知道”是 he does konw 还是 he does knows ,或者说“我过去的确知道”是 I did know 还是 I did known he acts as though he did not know anything 为什么时态不一样 英语时态问题,过去进行-和完成时.有什么区别 例如He was aways working-He had aways worded 助动词的强调句有固定的时态吗?在书上看到只能和一般现在时和过去时的肯定句连用,可是在they do have increased political power,就是现在完成时了,还有he did not think l had really done the work,but l did.这 his silence suggested that he ___ our plan.A.should not agree B.did not agree to C.not agree to D.would not agree with 我想知道的是D为什么不行呢?是因为时态还是因为后面的介词with?如果是因为时态,我倒觉得用过去将 for a long time 的时态搭配for 介词引导的时间状语常搭配完成时态或过去时态,请帮忙详细解释一下以下各句中的的时态使用的要求.1.---Did Alan enjoy seeing his old friend yesterday?--- Yes,he did.He hadn't seen 有点难理解的英语,有例句!通常什么had,什么would都表示是过去的时态,为什么有些词不表示过去时呢?像had.例句：If he had the money = If he had the money now .{but he does not have it.} 为什么Barely___time to catch the bus.用did he has?为什么要用的过去时did,而不是does he has 倒装这个我懂得,但是这个时态有点问题! he did not know 后面加任何时态的动词都可以吗? 问个过去时态的问句 Did he get up late on sundays?回答：Yes,he did.He did get up late on sundays.还是: Yes,he did.He got up late on sundays. he did not _____anything 英语倒装问题20.Only in an hour ago ____ out why he was absent.A.did the teacher found B.the teacher found C.did the teacher find D.had the teacher found 正确答案是C 才开始的时候 我选择了A 因为这句的时态不是过去时吗?
