happen vi.发生, 碰巧, 偶然
v.发生, 恰巧, 偶然发现
happen to sb.(or sth.)某人(或某物)发生...
这里的has happened at 里的at 是 at foerest (在森林方面).
句意:过去十年我国的森林发生了什么情况?
当然可以说what has happened in the office,意思是"在办公室发生了什么事",办公室本身不可能发生什么事,所以不能用what has happened to .上句亦是如此.
what ______foerest in our country in the ;ast ten years.
what ______foerest in our country in the ;ast ten years.
A.has happened do B.is happened to
C.has happened at D.is happening
但是结构是be happened to sb.难道说对物就该是be happened at sth.是这样的吗?
是不是也可以说what has happened in the office
A.has happened do B.is happened to
C.has happened at D.is happening
但是结构是be happened to sb.难道说对物就该是be happened at sth.是这样的吗?
