sort of 的意思 ?

請問 I sort of started the whole independence thing.
- sort of 在句中是副詞嗎 ? 可解作"有點"嗎 ?
用 kinda 代替可以嗎 ?


另外 :

1. a :I was wondering, do you think it would be possible,
if I got a $100 advance on my salary ?


b : I was just wondering, do you thnk there's a posibility
that you could give me an advance on my tips ?


句 a : 點解要用假設 It would be..., 用 it is possible,
if I get a ...可以嗎 ? 意思有分別嗎 ?


句 b : 改為 do you think it would be possible,
if you gave me ... 可以嗎 ?


2. 在美國電視劇 - Friends 中, 他們常用一些假設性句子
would..(如句1.a) .., 或是一些現在進行式, 覺得很難明白 ?

例如 : I am reading the book to the baby.
(劇中並不是有人正在讀書給baby聽
只是一位演員說已買了一本book,
有時會讀給baby聽.)

謝謝 !
