求a bit ,a few,a little（of）的区别?

a few,a little,a bit的用法：a few译作“几个”,a little,a bit译作“有点儿”。它们具有名词、形容词或副词的特点,在句中可充当主语、宾语、定语或状语。1。名词性词组：a few代替复数名词,a little,a bit代替不可数名词。如 My answers are wrong。Tell me a few。/ There is no milk in my glass,give me a little (= a bit),please。2。形容词性词组：a few修饰复数名词,a little修饰不可数名词,a bit加上of后修饰不可数名词。如 a few dictionaries / a little water (= a bit of water)3。副词性词组：a little,a bit可修饰形容词、副词的原级或比较级。a few不可。如 I’m a little (= a bit) cold。/ He is a little (= a bit) taller than Tom。注：(1) a bit还可写成a little bit,a bit of还可写成a little bit of(2) few,little前不加a时：a。通常表示否定含义,译作“几乎没有”。如 He made few mistakes。(注：few后仍接复数名词) / There is little coffee here,is there?b。在有些词组中,few前也不加a,却不表示否定含义。如 every few weeks (“每隔几周”),another few books (“另几本书”)(3)当few,little,bit前有quite,just,only时,必须加a。quite a few译作“许多的”,等于many,quite a little / bit也译作“许多的”,等于much。just a few / little / bit译作“就一点儿”,only a few / little / bit译作“仅仅一点儿”。(4)当few,little,bit后有more时,必须加a。a few more译作“另/再几个”,a little / bit more译作“另/再一点儿”。如 I want a few more bananas。/ Give me a little more fruit。(5)否定时,not a little译作“很、非常”(即“不是一点点”),相当于very或very much； not a bit译作“一点儿也不”,相当于not at all。如 She isn’t a little angry。(“她很生气”) / She isn’t a bit angry。(“她一点儿也不生气”)(6) few还有“少的”意思。如 This school has fewer classes。little还有“小的”意思。如 She’s a little girl。 再问： 那么a few后加上的名词要是复数名词吗？后面有要用be动词的话是用are吗？ 再答： a few 永远是复数概念，后面的名词用复数，后面的be动词用are 别忘了采纳我哦！
