convenience，vocabulary可数吗？

引导语：今天小编整理了两个比较常见而且有点让人分不清是可数名词还是不可数名词的两个词，希望可以帮助大家增加一点词汇量。

　　convenience

一、当 convenience 表示抽象意义的“方便”“合宜”时，它是不可数名词。如：

What sells CDs to most people is convenience. 多数人买CD是图个方便。

The hotelcombines comfort with convenience. 这家旅店既舒适又方便。

二、当 convenience 表示以下具体意思时，它则是可数名词：

(1) 表示具体的“便利设施”“方便用具”等，则可数。如：

They wouldn't like to live without modern conveniences such as microwaves. 他们不愿过那种没有微波炉之类现代化便利设施的生活。

用于惯用表达 as a convenience (to sb)，意思是“为方便(某人)”，与 for (sb's) convenience 大致同义。又如：

we group them intospecies merely as a convenience. 我们将其分类只是为了方便。

Thesupermarket offers a bag-packing service, as a convenience to customers. 为方便顾客，这家超市提供袋装服务。

(2) 表示“方便的'事”，也是可数名词。如：

It's a great convenience living next door toa post office. 住在邮局隔壁极为方便。

(3) 表示“(公共)厕所”，是可数名词。如：

There is a public convenience on the cornerof the street. 在街道的拐角处有公共厕所

　　vocabulary

既可以做可数名词也可做不可数名词，如：

1、a wide/limited vocabulary词汇量大/有限，就是可数名词。

2、The word has become part of advertising vocabulary. 这个单词已经成了广告用语。就是不可数名词。
