"Lay the groundwork" is an English expression that means to prepare the basic or necessary foundation for something. It is often used when talking about planning or setting up the initial steps for a project, idea, or event. For example, if you want to build a house, you first need to lay the groundwork by creating a plan, getting materials, and preparing the land.

「lay the groundwork」這個片語字面上是「鋪設地基」，延伸為「打下基礎、奠定前提」的意思。想像你在蓋房子，第一步必須把地基鋪好，否則後面的工程都會出問題；在語言裡，我們用它比喻為未來的計畫、研究或任何事情先做好準備工作。舉個例子："These early experiments laid the groundwork for modern genetics." 這句話強調早期實驗為現代遺傳學奠定了基礎。再如："Before we launch the new app, we need to lay the groundwork by conducting market research." 透過這些例句，你可以看到它經常與 for 或 by 接在一起，說明為了某件事、透過某種方式來「打下基礎」。下次想表達「先做好前置準備」，就可以自然地用上 lay the groundwork！

"Touch base" means to quickly check in or make contact with someone, usually to share updates or confirm details. For example, you might say, “Let’s touch base tomorrow about the project,” which just means, “Let’s have a quick chat to stay on the same page.” It’s often used in work settings but can also be casual.

當你在職場上或與朋友聊天時聽到「touch base」，可別以為真的是去『碰觸基地』喔！這個片語通常表示「再次聯繫、簡單確認進度或交換近況」的意思，語氣比正式的 meeting 軟性又快速，常用在電郵、訊息或口頭對話中，帶有『我們簡短聊一下就好』的感覺。比如說："Let's touch base next week to finalize the report." 意思就是先各自作業，下週再小小對焦一次；又或者你可以說："I just wanted to touch base and see how you're doing." 代表純粹想確認對方是否一切順利。用法上通常搭配 with someone（touch base with you/him/her），或者搭配時間副詞（tomorrow, later, next week），記得它是非正式用語，寫正式公文時就要換成 check in, follow up 或 discuss。希望下次你也能自然而然地說出「Let's touch base!」來保持好的人際連結。
