在所学语言中
英语中很多动词、形容词和名词需要固定的搭配伙伴，例如特定宾语、介词、to do、-ing 或从句；这些搭配往往要一起记。
depend on someone
depend on someone 中的 on 是 depend 后面需要的介词伙伴，不能随便换成其他介词。
学习者常在常见词后选错介词或句型，例如把 depend on 误说成 depend of，或在需要不定式、动名词时选错形式。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
