在有些“主语(通常是 I 或 It)+ be动词 + 形容词”结构中,可以省略“主语(通常是 I 或 It)+ be动词”。例如:
1. Nice to meet you . = It's nice to meet you . 见到你真高兴,辛会。
2. Glad to see you again. = I'm glad to see you again.又见到你真高兴。
3. Sorry I've kept you waiting so long.= I'm sorry I've kept you waiting so long.对不起,让你等了这么久。
4. Excited to be joining sports meeting. = I'm excited to be joining sports meeting. 这里的 to be joining sports meeting 是动词不定式短语作原因状语,说明
I'm excited的原因。
