82. There is no denying that you ___________(越仔细越好) in dealing with this matter.
解析：can never be too careful / can not be too careful
【考点解释】本题考查“越仔细越好”“再…也不为过”的固定搭配，即can never be too/can not be too + adj.
【原句精释】无可否认，处理这件事，越仔细越好。

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。

84. Much ___________________ (使研究人员感到惊讶)，the outcome of the experiment was far better than they had expected.
解析：to the researchers’ surprise
【考点解释】本题考查固定搭配 to one’s surprise 使…惊讶的是…
【原句精释】让研究人员大为惊讶的是，实验结果比他们的预计好得多。

85. Oh, my, I can’t find my key; __________________________（我一定是把它放在哪儿了）。
解析：I must have left / put it somewhere.
【考点解释】本题考查对过去事情的肯定的猜测，即must have+过去分词，leave与put都有放置的意思，但leave强调遗忘在…，较之put，leave更贴合题意。
【原句精释】天啊，我找不到钥匙。我一定是把它放在哪儿了。

86．I ________________________(宁愿加入你们去做义工)than go to the beach for a holiday.
解析：would rather join you as a volunteer
【考点解释】考查结构“宁愿…也不愿…”, 因题干中已存在“than go”的结构，只能使用 “would rather do rather than do”。加入… join sb
【原句精释】我宁愿加入你们去做义工，也不愿到海边去度假。
