答案： will come comes wouldn't come

答案d 第一个空句意我不知道她是否会回家，动作表将来，故用一般将来时态；第二个空句意如果他来，我就告诉你。条件句应用一般现在时态表将来，主句用一般将来时态。故选d。

I don't know if she will come. If she comes, i will tell you. but if I were her, i wouldn't come. 第一个选will come ,if 表示是否。 当if表示是否时，根据if后面的句子来确定时态。但是如果if(是否)前面的句子是过去时，if后面的宾语从句也要用相应的过去时态。因为有后面的句子，如果她来的话 表示她还没来， 所以用将来时。前面是i don't know是一般现在时，所以不需要把好面的时态改成过去时。（这样回答是否满意？）

will come comes wouldn't come 其实很简单，第一个if的意思是：是否，因为用了I don‘t know，按句意是这件事情还没发生，所以是whether she will come or not。
