英语常用短语用法

plenty的用法：

1、plenty指某物(特别是生存所需物品)已经足够了,即“充裕,大量,富庶”,间或含有过量或感谢的意味,通常是用在好的方面,且只能用于肯定句中。

2、plenty可指复数的事物,也可指单数的事物,其前可加不定冠词a,也可不加。

3、plenty常用于plenty of短语,表示“充足的,相当多的.”,通常只用于肯定句,其后可接可数名词,也可接不可数名词。plentyof作主语时,谓语动词要跟of后名词的数一致。in plenty意为“大量的”,在句中可作表语、定语或状语。

4、plenty用作副词时是非正式用法,意思是“相当地,充分地”,多用来修饰形容词,且其后可跟enough搭配使用。
