audience 英[ˈɔ:diəns] 美[ˈɔdiəns]，基本意思是“观众; 听众; 读者”，作名词使用。它是一个集合名词，大多以单数形式出现，既可以表示单数意义，也可以表示复数意义。作为整体用做主语，谓语单数；考虑集体中的成员时，谓语用复数。audience有复数形式audiences,是可数名词，用的比较少。

柯林斯词典给出的都是其词意用法，下面小编总结了audience的一些关于语法的用法说明。
1、audience 是集合名词，做主语时，其谓语可用单数或复数（作为整体用做主语时，谓语单数；考虑集体中的成员时，谓语用复数）。如：
The audience is [are] listening attentively. 听众都在聚精会神地听着。
The audience was [were] enjoying every minute of the performance. 观众对演出非常欣赏。
The audience is [are] always very excited by a wonderful goal. 一个精彩的进球总会使观众们非常激动。
2、形容听(观)众人数之多或少，通常用 big, large, huge, mass, vast, wide 以及small, thin 等形容词修饰，但是不用 many, few 修饰。如：
There was a large audience of young people at the pop concert. 流行音乐演奏会上有大量青年听众。
Her lecture had a crowded audience. 她的演讲挤满了听众。
The speaker had a small (thin) but attentive audience. 这位演讲者的听众不多(很少)，但很专心。
She felt nervous at having to sing before so large an audience [such a large audience]. 要在那么多观众面前唱歌她感到很紧张。
3、由于audience 是集合名词，所以 an audience 不是指“一个观众”，而是指某一群观众、某一个场次观众、某一方面的观众等。如：
She has never spoken to such a big audience before. 她以前从未向这么多人讲过话。
He loves holding forth on any subject once he has an audience. 不管是什么问题，只要有人听，他就爱大发议论。
同样地，audiences 也不是指“多个观众”，而是指多群观众，多个场次观众，多个方面的观众等。
Entertaining audiences is the purpose of movies. 娱乐观众是电影的目的。
The show had to be taken off because of poor audiences. 因观众太少而取消演出。
She has addressed audiences all over the country. 她曾向全国各地的听众演讲。
另外，audience作为集合名词，原则上不能用它表示个体，但every audience是例外，当要强调每一名观众时，可以这样用。如：
The pianist made a conquest of every audience for which she played. 这位钢琴家以她的演奏征服了每一位听众。
4、要具体表示观众的数量，可参考以下表达：
an audience of 10 000 1 万名观众
There were at least three hundred people in the audience. 观众至少有300人。
We scraped together an audience of fifty for the play. 我们张罗来五十个观众看这出戏。
The series has attracted an audience of more than 10 million. 这个系列片吸引了1,000多万观众收看。
An audience of millions watched the royal wedding on TV. 数以百万计的人们在电视上观看皇家婚礼。
不过，有时它也可直接受数字(尤其是较大的数字)的修饰。如：
The prince was cheered by a 10000-strong audience. 1万多名观众为王子欢呼。
Three thousand audience crowded the concert hall. 3,000 名听众挤满了音乐大厅。
若表示一名或几名观众，通常可以借助 member 来表示。如：
a member of an audience 一名听众或观众
One member of the audience described the opera as “boring”. 有一名观众说这出歌剧“乏味”。
The offending comment was in fact a heckle from an audience member. 这番冒犯性的话实际上是一名观众的诘难。
After the concert, several members of the audience came up and congratulated her. 音乐会后，几位听众走上来向她祝贺。
