以至于 (yǐzhìyú) means "to such an extent that" in Mandarin — you place it after a clause describing an extreme degree to introduce a surprising or dramatic result. This HSK 5 speaking lesson focuses on that one pattern so you can use it confidently in real conversation.
The key sentence is: 他太忙了，以至于忘了吃饭 (tā tài máng le, yǐzhìyú wàng le chīfàn) — "He was so busy that he forgot to eat."
Use it after a clause describing an extreme degree to introduce the surprising result. Think of the pattern as Chinese for "to such an extent that." You might explain that you were so nervous you could not speak, or that a book was so good you finished it in one night. The structure lets you connect the cause at its extreme to the remarkable outcome it produced.
In this roughly 10-minute live conversation, you talk out loud with AI teacher Mei Lin — voice, not typing. Mei Lin corrects your grammar and pronunciation in the flow of conversation and adapts to your level. You'll describe situations where something reached such an extreme that it caused an unexpected result, building the habit of using this pattern naturally rather than translating in your head.
