问题描述：
Tom has collected ____stamps as I have .A.twice as many B.twice so many
A和B之间有什么区别?
答
A
B 要用于否定句他们之间有什么区别？麻烦你能够说得更加详细吗？是哪里的知识点？我可以去看书as +形容词/ 副词原形++as ‘ …… 与…… 一样’，用于肯定句 not as / so + 形容词/ 副词原形+ as ‘ ，……不如…… ……’ （ 只有在否定句中才能用SO ）如果把这句话改为否定句就可能用B ，即： Tomhasn'tcollected twiceas / so many stamps as I have .
