it 用法
1.作人称代词，指代前面提到的事物

—What's the time now —It's ten past eight. 8:10.

it 用法
6.表示“喜欢、恨”等心理方面的动词，后面跟it后再跟从句，其从句作it的同位语
I hate it when people talk with their mouths full.
7.it还可用作形式主语、形式宾语以代替主语从句、宾语从句、不定式短语、动名词短语等
It's impossible to get there in time.
I find it strange that she doesn't want to go.
It + be + adj. + for sb. + to do sth. It + be + adj. + of sb. + to do sth.
反身代词
(1)反身代词在句子中作宾语表示反射(指一个动作回到动作执行者本身)，就是“某人自己”
eg：Don't play with the knife, you might hurt yourself.
(2)在句子中作同位语表示强调(即用来强调名词或代词的语气)。
eg：The story itself is good. Only he didn't tell it well.
(3)反身代词不可作定语。如果想表示“属于某人自己的”时，多用“名词＋of one's own”
不定代词
（1）some-一般用于肯定句中，any-多用于疑问句/否定句/条件句中。
eg：I want to tell you something important.
I can’t see anything. Did you do anything interesting
（2）在疑问句中，若要表示说话人希望得到肯定的回答或者表示请求、建议时用some-。eg. Would you like something to drink
（3）不定代词要视作三单，谓语动词用单数。
eg：Eveything looks good.
（3）不定代词定语后置
eg. something good
