a lot of 、lot of 、a few、much、many、some、any、or的用法

Answer 1

、a lot of = lots of,可修饰可数或不可数名词,意为“许多”, “大量的”,相当于many或much.a lot, a lot of, lots of通常用于肯定句,否定句中一般用many或much,如：
There’s a lot of work to do and a lot of people have been sent there.
有许多事情要做,许多人已派去那里了.
a little, a few：一些.a little形容不可数名词、形容词和a few形容可数名词.例:
I have a little money; I'm a little hungry； I have a few books.
little, few,指几乎没有,little形容不可数名词,few形容可数名词
much,many,表示很多,前者用于形容词比较级及不可数名词,后者用于修饰可数名词;例:
It's much easier now; There're much water in the tank; I have many books;
some, any,表示一些,前者用于肯定陈述及委婉请求,后者用于否定句及一般疑问句;例:
I have some books; Would you like some coffee? I don't have any books; Is there any coffee in your cup?
plenty of稍微复杂一点,用于口语表达时修饰不可数名词的程度而非数量多一些,但它也可以修饰可数名词,只是情况稍少些
a lot of, 相当于much,more的化身,但仅用于修饰名词,当后面接形容词比较级时,应为a lot;例:
There is a lot of water in the tank; There'are a lot of books in my room; I'm a lot better now, thanks.
