a bit 是指一點(diǎn)輕微的cold,而a little 指代不可數(shù)名詞的少
a bit和a little都作"一點(diǎn)兒"講,但用法不同.
1)a bit和a little在肯定句中修飾動(dòng)詞、形容詞、副詞和比較級(jí)時(shí)可以互換,表示"一點(diǎn)兒"的意思.例如:
The speaker spoke up a bit/a little so as to make himself heard more clearly.
演講者把嗓門提高了一點(diǎn)兒,以便使別人聽得更清楚.
2)a bit和a little在否定句中的意思恰恰相反,not a bit相當(dāng)于"not at all"(一點(diǎn)兒都不);not a little相當(dāng)于"very(much)"或"extremely"(很、非常).例如:
She is not a bit tired.(=She is not tired at all.)她一點(diǎn)都不累.
3)a little可以直接作定語修飾名詞,而a bit則要在后面加of構(gòu)成短語才能作定語,兩者都只能修飾不可數(shù)名詞.例如:
There is a little/a bit of food left for lunch.
午飯只能吃剩下的一點(diǎn)食品了.
4)a bit of的另一種形式是bits of,a little則沒有這種變體.例如:Besides this,he used part of an old army wireless set,and some bits of wood.除此之外,他還利用了一部分舊的軍用無線電發(fā)報(bào)機(jī)的一部分零件和一些木片.
