Семён, "a few" - это "несколько". "На улице" (когда речь идёт о расположении зданий) - это "on the street". Но никогда не "at the street".

Окей, с at the street жестко пролажался, но ты знаешь правило 5 хз какого класса "(a) few и (a) little?

Семён, believe me I know all the rules and I know them much better than you do. You make a lot of mistakes in almost every sentence you write but it's okay, you're still learning, eventually it'll get better ;)

And you probably have to repeat the rule you've just mentioned:)

I've even found it for you, here it is, do some reading: http://dictionary.cambridge.org/grammar/british-grammar/little-a-little-few-a-few
