其实,你的句子中的 on 与tonight 无关。这里的 on 不是介词,而是副词,意思是“(指节目、电影、娱乐等)在上演,在放映,在演出”。又如:<br>Look in the TV guide to see what's on. 看看电视节目表上有什么节目?<br>What's on at the cinema tonight? 今晚电影院演什么?<br>There's a good play on at the local theatre. 本地剧院正在上演一出好剧。<br>What time is the news on? 新闻节目什麽时候开始?<br>你的句子意思是:今天晚上会上演一个节目,你可能会喜欢。<br>There’s a programme on tonight which you might like.<br>句中的 on 是副词,修饰 programme,作定语;which you might like 是定语从句,也是修饰 programme;tonight 是时间状语。<br>注意下面各句中的 on today, on tonight, on tomorrow, on yesterday 均容易误解,其实其中的 on 与tonight, today, tomorrow, yesterday 均没有直接搭配关系,而是与句中的其他词有搭配关系或另有含义:<br>He’s got a tie on today. 他今天系着一条领带。(have got sth on 穿,戴,系)<br>What will you speak on today? 你今晚谈论什么话题?(speak on =talk about = 谈论)<br>The patient was operated on yesterday. 病人昨天动的手术。(operate on sb = 为某人做手术)<br>There may be a romantic movie on tonight. 今晚可能上映一部罗曼蒂克的电影。(on = 上演)<br>My shoes are similar to the ones you had on yesterday. 我的鞋和你昨天穿的鞋很相似。(have sth on = 穿)<br>Council members are due to have informal discussions later on today. 委员会成员定于今日晚些时候进行非正式讨论。(later on = 晚些时候)<br>All eyes will be on tomorrow’s vote. 所有目光都将聚集在明天的投票上。(on 与vote 有关)<br>The group will be performing live on tonight’s show. 该组合将在今晚的节目中进行现场表演。(on 与show 有关)<br>Film star Matt Damon is one of the special guests on tonight’s programme. 影星马特•达蒙是今晚节目的特邀嘉宾之一。(on 与programme 有关)
