我们去逛庙会英语可以说是 "Let's go to the temple fair." 来源方面，庙会这个词是由两个汉字组成的，分别是 "庙" 和 "会"，其中 "庙" 指的是寺庙，"会" 则是指集会、会议或展览会。因此，庙会就是指在寺庙举办的各种集会、展览会等活动。英文例句及翻译如下：

"The temple fair is a great opportunity to try traditional food and see local crafts." (庙会是一个品尝传统美食、观赏当地手工艺品的好机会。)
"I can't wait to go to the temple fair and see the acrobatic performances." (我迫不及待想去逛庙会，看杂技表演。)
"The temple fair is a popular event during the Lunar New Year celebrations." (庙会是农历新年庆祝活动中很受欢迎的活动。)
