It is easy to do.为什么do后面没有it 而Please show me how to do it有it

It is easy to do.为什么do后面没有it 而Please show me how to do it有it it is easy to do sth.跟it easy to do sth.这两个谁对?还是都是对的?还有为什么是I found it easy to learn English.而不是I found it is easy to learn English. it is very easy ,try to do it y___首字母 我记得是 it is easy to do sth为什么sometimes it isn't easy being the new kid at school.这句 easy 后面是being. it is ___(easy) to say than to do it is easy to It is easy to do A,but you'll find it difficult to do B.为什么不是it is difficult而是it difficult 连词成句；is/easy/It/do/to/ it is difficult to do 与 it is no easy thing to do 区别如题 It is -----（easy）to say than to do横线上填easy什么形式 Lucy finds it not easy to do the maths problem.为什么不是it is,讲下理由呢 I regret to say it is not always easy to do the right thing.thing为什么不加s? It is easy to say things ,but it is hard to do them.的翻译 Do you think the problem is hard If you think hard ,you 'll find it easy to work out 为什么选hard 和easy 还有例句 it is easy for sb to do sth我想问一下,it is easy enough for sb to do sth和sb is adj enough to do sth和sth is easy enough for sb to do的区别 it is 为什么不能用that 或this is 替代在比如说 it is easy for me to do the work. 为什么是It is easy to understand而不是It is easy to be understand为什么这里不用被动呢? 1.We found it very easy to do.这里面found 后面的it 为什么不加is ,不是it+is+形容词.这里very easy呢？在这里面做什么成分？
