在一篇英语文章中用的是过去时态,为什么if后面加一般现在时I realized that it doesn't matter if you don't understand every word 为什么在过去时态中if后面加一般现在时I realized that it doesn't matter if you don't understand every word什么是客观情况?then i started to write my own original sentence using the grammar i was learning中文意思是什么 if后面为什么跟过去时态?在什么时候if后面跟过去时态? 并列句不是要相同的时态吗.I bought some book,and all of them are interesting.为什么前面用过去时后面用一般现在时呢. if后面加什么时态 在一般现在时中someone后面的动词加s吗 关于I realized that it does not matter if you don not understand every word.句中的主句是一般过去时,那么宾语从句应该用过去时态的某一种,可此句的宾语从句为什么用一般现在时? if后面加动词的什么时态? 求英语语法分析beyonce的if i were a boy,i后面不是应该跟was么,怎么会跟were,还有,if后不是多加一般现在时或一般将来时么,为什么这里加的是were呢 As fire tries gold,so does adversity try virtue.为什么后面在一般现在时中adversity try virtue.这个try用原型,而不用改y为i加s呢?而前面的try加了s啊? 现在完成时后面是接什么时态啊在这句话中As you have already seen in Section A of this application,i have a good academic record,have already后面是接的过去分词,为什么在有些后面是接的过去时呢,比如这句话I ha even if 后面跟什么时态?一般时态,还是过去时态(虚拟语气) 为什么动词过去式直接跟在主语后面?还有一般现在时也是.例:I played football.I play football.play前面为什么不用加助动词之类的词? if i had…i would 的后面加动词是原形 还是 过去分词? if表示如果的时候,后面的句子应该加什么时态?一般现在时还是现在进行时?或者其他?或者没这种说法? 过去进行时态中的句子中when和while后面什么时候加过去式什么时候用过去进行时? not until then后面为什么加过去式不是过去完成式?then的时态不是过去式嘛?过去的过去不应该用过去完成嘛? 英语中所有动词都应用过去时态吧,因为所有做的事都是过去的,为什么还有的动词用一般现在时最佳答案者,再加30
