Be here to+verb這句話似乎在很多情況下都被頻繁使用。正式對話中經常使用嗎?

是的,這個表達式也可以用在正式場合!這在介紹某人或解釋某人參加會議或活動等的目的時特別有用。示例: Our guest is here to speak to us about the stock market. (今天我有一位尊貴的客人來解釋股票市場。) 例子: Jane's here to speak to us about equality in the workplace. (簡在這裡解釋工作場所的平等。) 示例: The marketing team is here to help us brainstorm solutions. = The marketing team has joined us to help with brainstorming solutions. (營銷團隊加入進來幫助提出解決方案。)
