a lot是口语中的一个常用词组,多用于肯定句,有时也用于疑问句.其主要用法有如下几点:
一、作名词短语,表示“很多;多量”,在句中作主语、宾语或表语,其后常有动词不定式短语作后置定语,如:
1.There is a lot to see at the party.聚会上有许多可观赏的东西.(作主语)
2.You know a lot about English names.你知道许多有关英语姓名的情况.(作宾语)
3.This is a lot.这真多.(作表语)
二、作副词短语,在句中作程度状语,表示“很;非常;常常”,修饰动词、感叹词、介词短语、形容词或副词的比较级,如:
1.It usually rains a lot at this time of year.每年这个时候都经常下雨.(修饰动词rain)
2.Do you wear your new watch a lot?你常戴你的新手表吗?(修饰动词wear)
3.He is feeling a lot better.他感觉好多了.(修饰比较级better)
三、a lot前可被such,what,quite,rather修饰,如:
I like him quite a lot.我非常喜欢他.
四、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 lot 在这里是名词成分。不是副词也不是形容词。
类似如:We have a lot in common.

a lot 本身是名词
a lot of 做形容词用=many/much

这好像本来就不是强调吧…
这个句子是双宾语的结构——“a lot about volcanoes”都是做直接宾语的,us是间接宾语
a lot本身既可以是名词性短语(比如本句中的)又可以是副词性的(比如 I like it a lot.)
应该清楚了吧O(∩_∩)O
