Question

a bit，a little bit和a bit of的区别

Answer 1

a bit和a little都作"一点儿"讲,但用法不同.
1)a bit和a little在肯定句中修饰动词、形容词、副词和比较级时可以互换,表示"一点儿"的意思.例如:
That's a bit too expensive.那有点太贵了.
The speaker spoke up a bit/a little so as to make himself heard more clearly.
演讲者把嗓门提高了一点儿,以便使别人听得更清楚.
2)a bit和a little在否定句中的意思恰恰相反,not a bit相当于"not at all"(一点儿都不);not a little相当于"very(much)"或"extremely"(很、非常).例如:
She is not a bit tired.(=She is not tired at all.)她一点都不累.
She is not a little tired.她很累
3)a bit用作定语时,意为“一点儿”,不能直接修饰不可数名词,但可用“a bit of ＋不可数名词”结构,此时a bit of ＝ a little． 如：
He has a bit of／a little money left．（他剩下的钱很少.）
She knows a bit of ／a little French．（她懂一点儿法语.）
4)a bit of a/an 口语,稍微,颇有几分,有点
eg.He is a bit of a coward.他有点胆小
找不到bit of的用法~但是a bit就表示一点的意思~
