新东方网为同学们整理了PTE听力听写训练，供考生参考学习。
训练步骤：
快速阅读：把文本copy到电脑上，用7s的时间快速把空格前后的单词看一眼。(温馨提示：PTE考试只有7S读题时间哦)
挖空听写：点击录音，不按暂停键，把空缺的部分补充完整，并做整体检查。
对答案改错：根据标准答案进行批改。拼写，单复数，时态，连词符，空格等与原文不符都算不对。
巩固强化：修改答案后，在重新听一遍录音(不暂停不快进)。
群上打卡见证进步：把听抄文本截图/拍照发群并@PTE助教-Jason，鼓励大家坚持，见证自己进步。
周末复习：每周六把周一到周五的错题再次进行强化与熟记。
题目：
The glucose seemed to make no difference to the bugs, nor to the ____________ systems of the mice. Instead, it altered the biology of the infected cells. In viral infections, many ____________ cells were committing suicide, a cellular ____________ strategy designed to slow the spread of the virus. Providing glucose seemed to ____________ their ability to fight the infection without resorting to such ____________ measures. The opposite was true for bacteria. Burning fat protected infected mice. But swamping the cells with glucose caused them to produce ____________ quantities of highly reactive chemicals known as free radicals, which damage cells. That collateral damage made survival less likely. The precise ____________ details of why glucose is good for viral infections and bad for bacterial ones are not yet known. And Dr Medzhitov’s results will have to be tested in humans before ____________ can apply them. But they are a useful reminder that there is sometimes ____________ wisdom hidden in folksy homilies.
正确答案：
immune， infested， scorched-earth， bolster， drastic， prodigious， biological， medics， genuine

译文：
葡萄糖似乎对轻微的传染病和老鼠的免疫系统没有什么影响。相反，它转变了受感染细胞的机理。在病毒感染中，许多受感染的细胞都在自杀，这种焦土政策旨在减缓病毒的传播。而葡萄糖似乎只想要加强他们对抗感染的能力，而非诉诸于自杀这种极端的措施。相反，葡萄糖对细菌感染影响重大。燃烧脂肪保护了受感染的老鼠。但给细胞灌满葡萄糖会使它们产生数量庞大的高度活跃化学物质，即破坏细胞的自由基。这种附带损害使老鼠更难存活。葡萄糖对病毒感染有益却对细菌感染有害的具体生物学细节还尚未可知。在医护人员运用研究结果之前，麦哲托夫博士仍需要做临床试验。但这些成果依然有效地提醒人们：有时候民间俗语中还是蕴含着大智慧的。
