不可數名詞, 像是:
Garbage、Furniture、Equipment、Information、Advice、Money、 Research、News、Luggage、Scenery和Architecture等等。

這些都是不可數名詞,不可數名詞前面是能不加冠詞或所有格的~
I see garbage on the street.
我看到街上有垃圾。 (Garbage是不可數名詞, 前面不須有冠詞或所有格)
當你加冠詞:
I see a garbage on the street(不正確)
I see the garbage on the street.(用"The"表示聽眾知道你在講哪些垃圾)
I don't see much garbage on the street.
我在街上沒看到太多的垃圾。("Much"只能用在不可數名詞,而且多數用在像這句否定句或是問問題"How much....?")
如何表達我看到街上有一件/好幾件垃圾?給它單位:
I see a piece of garbage on the street.
I see many pieces of garbage on the street.
用"Lots of" 或是 "a lot of" 則不須單位, 它們也都能用在可數與不可數名詞～
I see lots of garbage on the street.
我看到街上有很多件垃圾。
I see a lot of garbage on the street.
我看到街上有很多件垃圾。
I see little garbage on the street.
我看到街上幾乎無垃圾。(可數名詞則用"few", "little"大部份只能用在不可數名詞）
I see a little garbage on the street.
我看到街上有幾件垃圾。(可數名詞則用"a few", "a little"大部份只能用在不可數名詞, "little"比"a little"更少)
"Little"這個字,除了用在不可數名詞外, 也能放在可數名詞前, 但就不是來形容一些些的,而是形容人事物"很小一個":
He is a little kid.
他是個個子很小的小孩。

I see some garbage on the street.
我看到街上有些垃圾。("Some"能用在可數與不可數名詞, "some"用在不可數名詞是不用接單位的)

用Furniture做練習：

我從簡報中得到一些資訊。

This is bad news.
這是個壞消息。
