very few ___his address in the town

不对,very little leisure time
时间不可数,要用Little修饰

too的语气比very强,也有很多词组中too是表示"过分,太."意思 .
very 没有这个意思.
she is a bad girl 她是一个坏女孩（只是说坏,没别的其他意思）
The girl is too bad 这个女孩太坏了（强调她坏的过分）
从这些看出来,too few 强调太少
very few 只是说很少,语气没那么强烈.

B.Very few 不放于句首

few,a few,little,a little
虽然都表示“少”,但
（1）few,a few是可数的,little,a little是不可数的.
（2）a few,a little含肯定意味,few,little含否定意味.这里所谓的“肯定意味”和“否定意味”应该这样来理同样是半杯水,口渴者会认为：There is little water in the glass.而不口渴的人则会认为：There is a little water in the glass.
一：
1．few修饰可数名词复数.
2．few (= not many; hardly any)含否定意义；a few (= some; several; a small
number of) 含肯定意义.
3． not a few = no few = quite a few = a good few = many.
4． 当 few受 every,last,past,next,some,very等词所修饰时,表示肯定意义,few之前不再有冠词.如：
In the last few minutes,he checked up his paper again.
It took us some few days to repair the machine.
They are very few in number.
There were too few of them.
He goes to see his grandma every few weeks.
5． 在非正式文体中很少见,一般用或代替,如：
Only a few people attended the meeting.
另外,little / a little
Little remains to be done about it.(作主语)
A little remains to be done.
Please give me a little.(作宾语)
He knows a little of everything.
There is very / but little time left.(作定语)
Don’t worry; you still have a little time.
1． little修饰不可数名词,表示“量”.
2． little含否定意义(反义词：much)；a little含肯定意义(反义词：none).
3． 在非正式英语中,一般很少用little,常用not much,only a little来代替,如：
We haven’t got much money / time

Very是副词,副词只可修饰副词和形容词,由此可判定,few的词性为形容词,因为few后面肯定要跟可数名词而不是别的.但在本句中有省略,整个very few指代不少人的意思.

反意疑问句最重要的是后面的部分该怎么问,这是关键点.遵循前肯后否,前否后肯的原则.因为few是有否定含义的,所以后面的反意疑问句部分用肯定语气.所以very few 也表示否定,是几乎没有的意思.
例如：
There are very few apples in the box, are there?盒子里几乎没有苹果了,不是吗?

1.few 与 little 作形容词用,都表示“几乎没有”,相当于一个否定词.具体区别：(1) few 后面跟复数可数名词.e.g.few books few students (2) little 后面跟单数不可数名词.e.g.little water little food e.g.He has few friends.他没有几个朋友.They has little money.他们没有什麽钱 2.a few 与 a little 都表示肯定的意思,指“有一点,有一些”.具体区别：(1) a few 后加可数名词复数 （2）a little 后加不可数名词单数.e.g.I'm going to buy a few bananas.I can speak only a little Chinese.3.a little 与 little 也可以用作副词,表示“有点”“稍稍” 表示“很少” e.g.----Can you speak English?----Yes,but only a little.This book is a little more difficult than that one.（ 可修饰形容词比较级） She slept little last night.昨天晚上,她没有怎么睡觉

选C,尽管他在这里住了三十多年了,但很少人知道他的住址.very few虽然表示极少数,但仍旧是复数的概念,并从句子可知是一般现在时,因此选C!

1-5: FFTFT

very few
非常少,但够 几乎没有几个
too few
太少了
选VERY TOO一般放在句中

only a few还是表示肯定的,只有一点
very few 表示否定 几乎没有
a few = 一点,一些
few = 很少,几乎没有

复数,再少也是复数

很少 几个 非常少
