Quantum-effective gravity must lead to a regularized cosmology and thereby by itself source and regulate the high energy inflaton fields required for an appropriate inflationary beginning of the Universe. Pursuing this premise, we involve in the generic code of extended theories of gravity in conceiving semi-classical imprinting of quantum effects into gravitation. Hence, we prescribe a general semi-classical procedure of constructing the regular, quantum-effective form of the spatially flat FLRW cosmology whereby two alternative classes of the admissible dynamics are distinguished. In this paper, we explore only the particular class holding a minimally inflationary de Sitter UV-phase. Curiously, the low energy phase of the newly modeled Universe recovers the conventional dynamics of loop quantum cosmology. However, unlike the loop quantum cosmology, the high energy phase of the newly conceived cosmology has no bounce, instead, has a regular whimpering emergence of the Universe replacing the Big Bang. Our analysis manifests that without needing any non-standard equation of state, ordinary matter admits an inflationary beginning of the Universe.

量子有效引力必须导致规则的宇宙学，并由此本身来获得和调节宇宙适当的膨胀开始所需的高能膨胀子场。在此前提下，我们将引力理论的一般代码包含在将量子效应转化为引力的半经典烙印中。因此，我们规定了构造空间平坦FLRW宇宙学的规则的，量子有效形式的一般半经典程序，从而区分了可允许动力学的两个替代类。在本文中，我们仅探讨具有最小膨胀de Sitter UV相的特定类别。奇怪的是，新近建模的宇宙的低能相恢复了回路量子宇宙学的常规动力学。然而，与环状量子宇宙学不同的是，新构想的宇宙学的高能相没有反弹，相反，宇宙在不断取代宇宙大爆炸而不断发出微弱的声音。我们的分析表明，在不需要任何非标准状态方程的情况下，普通物质可以接受宇宙膨胀的开始。
