a lot ,a lots,a lot of,a little,a few,bit...要怎么区别,他们的用法.不要用官方语言说,有自己的话大
a lot ,a lots,a lot of,a little,a few,bit...要怎么区别,他们的用法.不要用官
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
只有a lot of ,lots of 这两个短语,都表示很多,他们之间没有什么区别 可以互换
a little 只修饰不可数名词;a few只修饰可数名词,都表示很少,
bit可以与a little 构成a little bit of 或是a bit of 都表示很少
