The code labelled “Block 2” does not correspond directly to any code in the recursive function; it is pure incidental complexity. When we find ourselves processing a FoldTreeFrame it may be because we are entering it for the first time after a parent call created it, or it may be because we are re-entering it after a child frame’s execution completed. This means that, before we make a recursive call in block 3, we need to check whether that call has already been completed. If so, we run whatever logic should happen after the recursive call. In this case there is no such logic in foldTree so we only need to deal with the mechanical concerns of returning to our parent frame.
张咏梅：人数少了，为小班化教学创造了条件。小班化教学真正落地，要分两个层面，一个是硬件，即师资、设备设施要配齐，一个是软件，关键是思想问题。千万不要认为小班化只是人数减少，如果30个人和60个人的班，老师还是一样的教法，那小班化的意义就没了。很多人觉得，人数少了，老师负担是不是轻了？其实恰恰相反，老师的要求更高了，压力更大。因为小班化教学的目的，是要兼顾每个孩子，实施个性化教育。
