·谁能帮我找一下rather的用法

rather

ad.
1. 相当,颇,有点儿
I'm feeling rather sleepy.
我有点困倦。
2. (常与would或had连用)宁可,宁愿;(与其...)倒不如;而不是
He would rather play than work.
他宁可玩,却不愿工作。
I'd rather you knew that now, than afterwards.
与其以后让你知道,不如现在就让你知道。
I'll never be dependent on anyone again. I'd rather starve.
我再也不依靠任何人了。我宁愿饿死。
3. (常与or连用)更确切地说
He left late last night, or rather early this morning.
他昨夜很晚,或者应该说是今天一大早才走。
4. 【英】(用于回答问题)确是如此;当然

课文中出现的一句话:
They knew， or rather thought that their father was on the same train. 他们知道,或者说他们认为他们的父亲是在同一列车上的.
这里or rather是固定短语,意为"或者说;更确切地说".那么rather还有哪些用法呢?

一、 用作程度副词,意为"稍微;有点;颇;相当"

1. rather可以修饰形容词、副词的原级、比较级等;可以与介词短语连用.如:
She was rather hurt by his unkind words.
She's rather better today.
She looks rather like her father.
These materials are rather too difficult for the seniors.
2. rather放在不定冠词a（n）前后均可.如:
