if you ___ me,i shall be grateful to you.
A helped B will help C are helping D will be helping
请问ACD错在哪里呢will 这里是指将来还是愿意?

B will help
这里应该是表达将来,主要是shall 有将来的意思,所以这里也用了will来对应.
祝好!
如果不懂建议重新提问,也可以直接追问哦.
再问：那是我记错了还是什么有种情况不是用过去时代替表示将来的吗
再答：你说的是虚拟语气吧，嗯，如果是虚拟语气，那是对的。但是这里可能情况是：事实已经发生了，你已经帮了我了。然后这就叫做：真实条件句，语法规定：从句用一般现在时表一般将来时，而主句就用一般将来时，故只有b符合要求。
再问：恕我不明白从哪里看出已经发生了如果是虚拟这个句子应该变成什么样子的
再答：从哪里看已经发生，从shall 有这个含义。同时最好有全文。中国考试就喜欢这样子，给你一个片段，然后又要你考虑全文，很无聊的考试。
