英语大人进啊

some有一些的意思
some用在肯定句，I bought some books yesterday.

另外，some有某个的意思，如some day 某天

many是很多的意思。
many修饰可数名词，如many books, many people……

一般来说，begin to do和begin doing可以互换，但在以下三种情况下，用to do：

1. 主语不是指人，而是it等。如：It began to rain.

2. begin后接表示心理活动的词。如：begin to know
believe， wonder， think等。

3. begin本身是ing形式，为避免重复后接to do
即，beginning to do

P.S
doing 一般有正在做的意思
to do一般有正准备做的意思
所以doing 就是开始做了to do开始要做,还没做

一楼回答，不错，楼主太粗心了，全是错别字，我是看不懂

你是不是写错了, 应该是many 还有 begin to do sth 吧.

many usually put in front of the accountable nouns, but for some, you can either put it in front of the accountable or the unaccountable nouns.

e.g. i have many books.
i have some money./ i need some apples. etc

begin doing sth and begin to do sth can actually use in the same way, they both using for the future tense.

e.g. i begin learning english./
