3句英文任你选

Our general manager Mr. Wu asked me to say "hello" to you.
我们的总经理吴先生让我转达他对你的问候。

He meant to come here to meet you in person.
他本打算亲自来接你。

But some other business held him back, so he asked me to come in his place.
他因公务缠身，才由我替他来接你。

半个句型要记牢

in person(亲自)

Tip:

固定搭配，相当于 personally。另外注意 ask me to say hello to you和 take/ give my greetings/ regards to sb.的区别，前者是转达某人对对方的问候，后者表示要对方代自己向某人问好。
