it doesn't matter后面加that还是if?

都可以。例句： It doesn't matter that you can't come. 你不能来也没关系 It doesn't matter if/whether you will come. 你能不能来都没关系

可以，that带的从句可以做形式主语it的内容，通常口语中that部份都省略了

本身是一个小句子了，所以后面可以跟一个对为什么it doesn't matter的进一步解释。或具体内容，或是其实。It doesn't matter,tell me,I just want to know your opinion.没关系，给我说，我只是想听听你的意见 does it matter后用that跟一个从句,that 可以省了。does it matter that if I won...

it doesn't matter 是指不重要，无所谓、无关紧要。1. It doesn't matter much whether we go together or separately.我们一起去还是分头去都可以。2. It doesn't matter to me whether you go or not.你去或不去，对我都没关系。3. It doesn't matter how far it is; we can go ...

都可以加,I doesn't matter本身就是一个完整的句子,后面可以接从句,来对此进行限制.if 和whether都是引导条件从句.

完全可以，和whether意思一样，表示“是否”， 甚至比whether还要常用。如： it doesn't matter if she apologize or not.√ it doesn't matter whether she apologize or not .√ 但这种从句置于句首时，不能用if, 只能用whet her. if she apologize or not doesn't matter. X whether she ...

It doesn't matter. 没关系（无所谓/不要紧/无关紧要)。1．It doesn't matter．单独使用(即其后不接词)时，也可说成That doesn't matter．其意为"没关系"(主要用来回答道歉和表示某事不是很重要)。例如：A：Would you like to go fishing with me？你愿和我一起去钓鱼吗？B：I'd like...

你好。都可以用，只是意思不一样。1 It doesn't matter if you can't come tomorrow （翻译：你明天不来没有关系）--- 这是主语从句。it是形式主语。if you can't come tomorrow 是真正主语。这里的if指代条件，解释为“如果”。2 It doesn't matter to me whether he will come or not...

前面是主句，后面是if的条件状语句。意思是："如果做。。。没关系，不要紧，不重要"等。如：it doesn't matter if you come late.如果你来晚了，没关系。

看对话情形啦 举个例子 如果对方表示道歉，应该用it doesn't matter 如果是感谢，就用that's ok 综上，所以是that's ok
