第二个表被动 什么问题被解决
类似问题
类似问题1：There is another problem need to be solve/solved?不确定是用solved还是solve,为什么呢?[英语科目]
There is another problem need to be solved?
当然是用“solved”
这个很容易判别,"to be + 过去分词" ----> 被动式
例如:There are lots of things need to be done.（尚有很多事情待办.)
类似问题2：He had a lot of problems to(solve还是be solved)[英语科目]
to solve

类似问题3：.I was calling because of a problem that needed ___.A.solve B.solving C.to solve D.to be solved正确答案是D,但是B为什么不行?[英语科目]
因为solve这个动作的定语从句中的主语that承受的,两者之间有动宾关系,而B用了现在分词形式表示主动意义,只有用不定式的被动结构才正确.
类似问题4：The problem was too difficult to be solved还是The problem was too difficult to solve?[英语科目]
用后面的.be 动词后面的形容词如果是easy/difficult等的话,动词不定式只要用主动的.
类似问题5：With the matter (to solve/to be solved),they could not go to play.是不是都对?[英语科目]
With the matter (to solve/to be solved),they could not go to play.
应该是to solve因为不定式的逻辑主语 是句子主语they.根据后面句子意思判断
to solve的执行者是句子的主语 故不定式应该用主动形式.
