"说到…" — Speaking of / When it comes to... 话题转换句型
母语者切换话题时几乎不会说 "About X" 或 "Regarding X"——那太过书面。日常对话里，他们用 Speaking of 进行顺势联想，用 When it comes to 引出观点。两者看似相近，但使用场景有明确区别。学会这两个表达，你的对话衔接会自然很多。
Speaking of + 名词/动名词 — 从当前话题"顺延"
Speaking of 的核心功能是：上一个对话里出现了某个关键词，你顺势说出和它相关的事情。它是一种自然的联想跳跃——前文必须提过这个词，不能凭空用。
Speaking of movies, have you seen the new one by Nolan?
说到电影，你看过诺兰的新片吗？（刚才的对话里提到了电影）
Speaking of coffee, there's a great new café down the street.
说起咖啡，街角新开了家不错的咖啡馆。
Speaking of travel, are you still going to Tokyo next month?
说起旅行，你下个月还去东京吗？
Speaking of hard work, Xiaoming has been putting in 12-hour days lately.
说到努力，小明最近每天干12小时。
不能凭空用 Speaking of。如果你和朋友在聊天气，突然说 "Speaking of alien invasions..." 会很突兀——除非刚才的对话确实和外星人有关。Speaking of 要求前文有关联词。
When it comes to + 名词/动名词 — 引出观点或专长
When it comes to 更像"在某个领域/方面"，用来引出你对这件事的看法、经验或评价。它不需要前文铺垫，可以独立开启话题：
When it comes to cooking, he's a total expert.
说到做饭，他是个完全不折不扣的高手。
When it comes to making decisions, I tend to overthink.
在做决定这件事上，我容易想太多。
When it comes to learning English, consistency matters more than talent.
学英语这事，坚持比天赋重要。
When it comes to the budget, we'll discuss that in the next meeting.
至于预算，我们下次会议再讨论。

B: Amazing. When it comes to ramen, that place is the best in the city. As for the price, it's actually quite reasonable.

这两个句型属于"学会就能立刻用出来"的类型。下次聊天尴尬沉默时，在脑子里搜一下对方刚才说了哪个词，然后用 Speaking of 接上——你的对话会立刻自然流畅很多。
