the golden fish is easy to take care of可以替换it's形式主语吗

he golden fish is easy to take care of=it's easy to take care of golden fish 如果可以那么其他任意的也可以吗.) 括号里的it'？（如：it's a very bad thing to watch too much tv

It's our duty to keep our classroom clean and tidy. ******************************************************************* 加油！不明白再问！如果帮到你，请及时采纳，谢谢It's important to learn English well;s +名词/形容词+ to do sth 固定用法 又如 It'

这是一个句型：It is + 形容词或名词 + to do sth. 如：It's easy to get to school. (七下4单元) It's his job to walk the dog at home. 在家里遛狗是他的事。

你好！ 在这个句型中，不定式作真正主语，be动词后可以是名词和形容词 It + is/was + adj./n. (形容词或名词） +to do sth. 仅代表个人观点，不喜勿喷，谢谢。
