Question

What’s in the box? ----_________. A. It’s a shirt B. There i

Answer 1

答案是B.

“盒子（箱子）里面有什么?”----“里面有一件衬衫”.

what's in the box和 what's that in the box有区别.

---What's that in the box?

---It's a shirt.这里的it就是问句中所指的that

如果用there的话就是there be 句型的了 比如说:

---What's in the box?

---There is a shiirt.

因此,关键在与是否有that的存在.
