1.It is tiring to climb the mountain. 2.It is difficult to write poems.的同义句

1.It is tiring to climb the mountain. 2.It is difficult to write poems.的同义句

这是典型的it做形式主语的同义句转换，如下：
1.To climb the mountain is tiring.
2.To write poems is difficult.
说白了就是就是去掉形式主语it，用后面的不定式来代换就可以，不过仅限于这种情况，切不可按部就班。。

你好！ To climb the mountain is TIRING ,WHICH IS AS DIFFICULT AS WRITING POEMS . 希望对你有所帮助，望采纳。
