C 表已经发生的事 用完成时排除B、D
题干中已出现to 排除A
你的题应该是
What ____to the forest of the USA in the last 350 years?才对吧
c
happen是没有被动形式的，is happened 是被动形式
IS haooened错,不是进行时
happen哪有被动语态,没be happened
BD肯定不行
AC不一样的,
有两个TO的吗,答案错,要不你打错
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
不对 to to ，只有
happened to +sb，sth
选C
我认为应该是what has happened to the forest for the USA in the last 350 years(在过去的350年中,美国的森林发生过什么?)
如果是这样
what it has happened to to the forest for the USA in the last 350 years
应该选A

选C

如果是这样
what it has happened to to the forest for the USA in the last 350 years
应该选A
但是在正规英语中what's一般代表what is ,如果原题如你所写，建议选A
收起
过去时，
排除BD
选C
C; 过去350年里发生了什么事情，就是以前到现在，用一般完成时。
