备考-pte包4.鸡精每月speaking-part

免费PTE台PTE.AI黑科技学台©2018s备考PTE是一个不断努力自我的过程。每一个PTE考生在复习过程中，都一定受到了其他PTEer或多或少鼓励和无私的。也许和他们从未谋面，素不相识，但其他同学给予的帮助，却是那么的真真切切，异常珍贵。尤其是在机经的整理上，如果没有众多同学细致的整理和无私，一份份宝贵的机经将无从而生。那么许多同学与PTE的分手也一定会走得更加坎坷。对于这些无私的同学，“PTE黑科技十分感激，并想在这里地说一声：“老铁，谢谢！”因此，已经成功和PE分手的，也希望尽自己努力去帮助，回馈广大还在和T“搏斗”的考生朋友们。在对过往的进行了细致深入的统计和研究后，毅然决定把研究成果无偿地给广大T考生！以此作为我们对曾经帮助过的朋友的感谢和对后来者的回馈。衷心希望的成果能帮助大家在尽早拿到想要的分数，和PTE分手。但历经两次换题季后，T机经总数已达几千题，但这几千题中，已有近半的题不再考了，或者超低频出现。如果把这些题筛选出去，这将极大的提高同学看机经的效率。但一两个人肯定无法对其筛选，这需要所有Per共同协作。为了达成这一目标，的“蜂巢行经平台升级了，小伙伴们可以进入“E.A黑科技”的小程序，与大家实时互动，点赞告诉大家考了哪些题，还可以对原有的机经进行实时修正和补充。解决PDF机经使用说明本PDF源自PTE.AI黑科
