what it has happened to to the forest for the USA in the last 350 years 为什么?
what it has happened to to the forest for the USA in the last 350 years 为什么?
这句话有问题,因为:
1 多了一个to
2 应该用forest of the usa
3 最大的问题在于这句话不完整,首先一句完整的句子要有主语和谓语,但是这句话中没有谓语,what引导的成分叫主语从句,他所指代的内容是350年前美国森林所发生的事情,整个句子充当主语,但是后面什么也没有,所以这句话要使完整的话可以这样改动:what happened to the forests of the usa in the last 350 years made us aware of the importance of plants(350年前美国的森林所发生的事使我们意识到了森林的重要性)
4 如果你把这句话作为特殊疑问句,则不要上面的3,而把it去掉,根据句子的意思是主语发生在森林,而这句话提问的是主语,所以在特殊疑问句中当提问主语(疑问代词指代主语时)主语要省略,所以把it去掉,并加上上面的1,2两条这句话就对了.
不对
只有happen to+人或物,没有happen to to+人或物,
我肯定
It tell us what has happened recently_____________________ 填单词
2-16.Plase tell me what has happened ,when it happened ,how it happened and what has done about ithas done 错了 应该改为 为什么~

to see what you have seen before it has happened 尤其是 before it has hap尤其是 before it has happpened 为什么用完成时呀?thanks
What has happened proves that my advice is right.what后的主语从句可以换成when it happens
do you know what ( ) just now.A.was happened B.happened C.has happened D.has been happened
是what has happened to还是what has happened at快,还有后面加什么!
