“If there were the day ...”后面虚拟时态怎么用?明天要交..英语作文题目

不好意思,说一下你句子的问题,第一：先不说时态.你的句子中有两个谓语动词,be动词虚拟和disappear,一个句子不等由两个谓语动词.以后留心一下,两个谓语动词出现在一个句子肯定是错的,所以用介词短语或定语从句来代替.如：If there were the day without pollution.(介词短语)或：If there were the day having no pollution.（have + ing 做形容词）或：If there were the day when there had no pollution/when pollution dispeared（定语从句）（当然,如果你是特意在pollution前省略了先行词that,when的话,那就是正确的）.第二：说时态问题.你这里if主导的是从句（其中双谓语动词的问题上面说了）,你还应该考虑主句的时态.即,假如一天没有污染,我会...,后面半句的时态（即主句的时态）的才是问题的关键.下面给你解释一下这类句子,虚拟的句子这样理解,以后一通百通了.举个例子作比较,If I were you,I would tell him.（事情没发生,意思是“如果我是你,我将告诉他”,表示将来）If I were you,I would have told him.'（事情已经发生过了,而我没有告诉他,所以翻译为“如果我是你,我就会告诉他”,表示过去,但已经不能改变了）只有这两种可能.所以回到你的问题,如果有一天没有污染,我会（怎样怎样）.表示事情发生是在将来,所以用if there were the day without pollution,I would ...大致就这样,加油哦======以下答案可供参考======供参考答案1:if there were the day when pollution disapeared,或者楼上那个供参考答案2:有一天没有污染If there were the day without pollution这个地道供参考答案3:你这里要表示的是虚拟语气，所以除了对正常叙述的描写，其他都用虚拟语气要表达 有一天没有污染 if there were the day without pollution, 后面再跟主句，主句用的是将来完成时,或者一般将来时if there were the day without pollution, our earth will be better（将来完成时）还有 if there were 前面是 were 后面就一定要用 过去时态 if there were the day that pollution was disappeared, 后面再更从句, 比如 i will go to play with my friends day and night.(一般将来时)希望对你有帮助！

谢谢了
