A question What about Grammar of ENGLISH
He informed me that he was going to Europe on business
我想问为甚麼在这句话里没有用 is going to 而却用了was going to
答
他当时正准备去，be going to 是将要去，他过去将要去，是过去将来时，所以用was
答
因为前面用的是过去时informed，从句也要用过去，所以用was
答
时态要一致
答
因为前面是一般过去时：He informed me that ，所以后面也要用相应的时态
答
前面主句的谓语动词就可以看出,通知你时 就已经是过去式了,那么他去欧洲的打算也是那时候打算的,而且主句和从句的前后也要时态一致.
