关于过去分词的三小道英语题
用括号里动词的正确形式填空
1 The teacher ____(invite) to the concert arrived on time.
正确答案是：invited
为什么填was invited是错误的?
2 The problem ____(discuss) at the meeting now is serious to us
正确答案是：being discussed
为什么填 discussed 是错误的?
3 All of us were puzzled by the puzzling question ____(raise)by a little girl
正确答案是：raised
为什么填 was raised 是错误的?

Answer 1

供参考
答这类的问题
首先要认清句子中的’动词‘(verb)
(1) 是 arrived
所以 invited 不能是动词
而要是作为形容词(形容teacher)的’过去分词‘
这也就是说不可以有 was
若然有 was
便成为了动词
(2) 动词是 is
所以discussed 要是’过去分词‘
这点与 (1) 的道理相同
但有一个不同之处
就是 now 这个时间的副词
这说明’现在正被讨论之中‘
所以单是 discussed (被讨论)是不足够的
要加上 being (正在)
例﹕The man looked at the boy.
The boy was looked at by the man.
The man is looking at the boy.
The boy is being (正在) looked at by the man.
(3) 动词是 were puzzled
所以 raised 前面就不能有 was
