pleasure ¹

当笼统地指与痛苦相对而言的“愉快”“快乐”时，pleasure 是个不可数名词：

1. I get a lot of pleasure from listening to music. 听音乐使我得到许多乐趣。

2. small gifts that give a lot of pleasure and don't cost much 使人得到很多乐趣而花钱不多的小礼物

当具体地指“愉快的事儿”“乐事”时，pleasure 是个可数名词(参见 success, abstract nouns):

1. It's been a great pleasure to talk to you. 和你交谈真是一大乐事。

2. ‘Thank you for doing that!’ ‘It’s a pleasure.’ “多谢你做了那件事!”“不客气。”

3. “Goodness, six zeros! What can I say?” “It’s my pleasure.” “天哪！六个零！我还能说什么呢？”“这是我乐意做的。”
