问题描述：
They are heavy boxes that you can’t carry many at a time.
They are ——— heavy boxes that you can’t carry so many at a time.
A.so B.such
答案a为什么,怎么看这个句子的中心词?
答
B
so 后面是形容词,当后面是名词时little(少),few,much,many等才可以用so
such后面试名词,heavy boxes 是名词所以B
改成They are ——— heavy the boxes that you can’t carry so many at a time就要用A了因为是形容词heavy可答案是a啊认为是B原因同上
