you are not as close to your parents as you are used to be 这句话中used to 后面为什么要加个be
问题描述：
you are not as close to your parents as you are used to be 这句话中used to 后面为什么要加个be
答
其实口语里面加不加都行，但是正规的来说是要加be的。 这句话可以这样说 you used to be close to your parents，to 后面要加动词的原形所以要用be，如果没有used to就可以说成you were close to your parents。为什么要用be其实跟ARE有很大关系。举个例子you ARE taller than you used to be这里面的be其实就是为了对应前面的那个ARE。如果一个句子里面没有be动词就简单了，例子：i like him as much as i used to
答
used te be表过去常常，是一种状态，所以用BE
答
这句话原本是：you are not as close to your parents as you are used to be close to your parents.
