lt is good for my healthy 这个lt is 必须是这样吗 难道不能把它改成they are请说明原因
lt is good for my healthy 这个lt is 必须是这样吗 难道不能把它改成they are
请说明原因

lt is good for my healthy 这个lt is 必须是这样吗 难道不能把它改成they are请说明原因
其实很简单,不可数、单数用——it is
可数、复数用——they are
楼下的已经举过例子了,我就不再举例.
但是,给你另一种思考方法:
其实你要掌握的,是一个重要的句式:
It is + 形容词 for sb.to do sth.
比如,It is good for me to eat apples.吃苹果对我有益.
而sb.也可为sth.那就是It is good for my health to eat apples.吃苹果对我健康有益.
随着你学习的深入,还会学到it is +名词 for sb.to do sth.
比如,It is time for her to go home.到了她该回家的时间了.
注意,这个句式中,for sb.和 to do sth.都是可以省略的.
省略to do sth.时,句子的意思就成了泛指.
比如,it is good to eat apples.吃苹果是有益的.
而省略for sb.时,就必须在前面再加一个句子.
比如,I eat apples.It is good for me (或for my health)——这里的it 代表“eat apples”
也可为:I eat apples.They are good for me.——这里的they 代表“apples”
也就是说,这句句子,用it 和 they都可以,侧重点不同.
当然,如楼下说的,如果是不可数或单数,就不能用they了.
关键是,记住It is + 形容词 for sb.to do sth.这样就不用为they 而烦恼了.
拒绝【华人学用英语团】无耻抄袭!

在中学的时候it is + 形容词 for sb. to do sth. 是固定用法,但是并没有解释为什么要用 it is
其实这里 it is 非常容易理解,it 是一个代词,而根据 it 是单数,所以要用 is 来表示单数。
那么为什么要用 it 呢?它指代的是什么?它能指代的有很多不同情况。
① 指代单数个体:It is an apple. It is good fo...

在中学的时候it is + 形容词 for sb. to do sth. 是固定用法,但是并没有解释为什么要用 it is
其实这里 it is 非常容易理解,it 是一个代词,而根据 it 是单数,所以要用 is 来表示单数。
那么为什么要用 it 呢?它指代的是什么?它能指代的有很多不同情况。
① 指代单数个体:It is an apple. It is good for my health. 这里it就是指代apple,在这种情况下,显然是不能够替换成they are的;但是如果,these are apples. They are good for my health 这样就可以了
② 指代事件,动作,事实时一般都用单数,所以是it:I like swimming. It is good for my health. 这里it指代的就是我喜欢游泳这个事实,而是这个事实对我的健康有好处,所以只能it is而不能用they are,因为显然事件是不能够用复数形式的。
若不懂,请追问,望采纳!
