He doesn't know ______ English because he has studies it for only_____weeksA much...a few B little...few C few...a little D a few...a littlewhy?

A. 根据意思, doesn't know much English 不懂多少英语 的原因是 he has studied it for only a few weeks 刚学了几周而已

选A。
因为English是不可数名词，week是可数名词。
考点：可数名词用：more,few修饰。不可数名词用：much,little修饰。
翻译：他不怎么懂英语，因为他只学过几周！

A
用法
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

A much...a few
第一个空不可数
第二个空可数

A
语言是不可数名词,故排除C与D,根据句意：他不懂很多英语因为他只学几周,故B也错
