83. Only when I reached my thirties __________________________ (我才意识到读书是不能被忽视的)

解析：did I realize that reading cannot be neglected

did I realize that reading is unignorable

【考点解释】本题考查由only when 引起的局部倒装。当only when置于句首，主句用局部倒装，即将助动词置于主语前面。only when引导句子时态为过去时（reached），为保持时态一致，主句助动词用did；注意被动语态的使用，reading与neglect为被动关系。同时也可以使用be+adj的结构。

【原句精释】直到三十岁，我才意识不能忽视读书。
