各位大神好，我有一个关于虚拟语气的句子，不知道对不对，请指教。
If you could had come with us, we would have been pleased.虚拟条件句的谓语一般不用could。
过去：had done现在：过去式（were)将来：were to do\\\/过去式\\\/should+v改为：If you had come with us, we would have been pleased.
虚拟语气句子
D if only I had not been there 要是我没有去过那里就好了。
事实是去过了，与过去事实相反所以用虚拟语气。
虚拟语句是什么
定语从句:A good friend is a present that you give yourself.宾语从句:I know you will try your best to love me .
关于虚拟语气
这是if引导的条件句...........虚拟语气是与事实相反...........才用............
