(A) is a good reply because it shows the listener already knows about the new office and adds helpful information (they will work with the Marketing and Research teams).
(B) fits well because it confirms the news (“Yeah…”) and gives an extra detail (the branch will focus on tech services), which keeps the conversation going.
(C) also works because it reacts naturally (“Wow, that’s big news”) and then asks a logical follow-up question about whether the person plans to move or change jobs.
(D) is less suitable here, because it jumps straight to commuting arrangements without first showing understanding of the basic news.
The word "branch" can refer to several related ideas. Literally, it means a part of a tree that grows out from the trunk. Figuratively, it can describe something that splits off from a main part—like a branch of a company (a separate office or store in a different location), a branch of government (such as the executive or judicial branch), or even a branch of knowledge (like biology or history). In all cases, a "branch" suggests something that extends or divides from a central source.

艾宾豪斯的遗忘曲线遗忘的过程最常用「遗忘曲线」来解释(又叫艾宾浩斯曲线,以 19 世纪 80 年代的德国心理学家赫尔曼·艾宾浩斯命名)。这条曲线描述了随着时间过去,我们对学过内容的记忆会逐渐减弱。
根据遗忘曲线研究显示,我们在学习后短短一天内就会忘记约 65% 的内容,一周后甚至可能高达 75%。这也是为什么学语言常常觉得学了又忘、进步缓慢。如果没有用对方法,努力可能很快就被大脑「清除」。
如何学得更快、记得更牢
为了帮助你突破学了就忘的困境,我们打造了 MyLingo Tutor - 一套聪明又高效的学习系统,专为加快语言学习与提升记忆力而生。它会针对你学过的每个单字建立专属的「学习曲线」,自动安排最佳的复习时机,让你在对的时间复习对的内容,有效防止遗忘,让学习变得更轻松、更有成效。
下图展示了 MyLingo Tutor 如何追踪你的学习曲线,并精准安排复习时机,有效强化长期记忆。
