A similar twist with an extended human arm would start with the thumb pointed slightly up at the top of the flap, then the arm would turn so the thumb is parallel to the ground in the middle of the flap and continue down until the thumb is pointed toward the ground at the end of the downstroke, Thomas says.

托马斯介绍说，对于人伸出的一只胳膊，类似的扭转应该是：在开始拍动动作的最高位置，拇指轻微上指；然后胳膊旋转，这样拍打过程中拇指会与地面平行并连续下降，直到下降过程结束时拇指向下。

With John Dunstable and other English composers, partly through the local technique of fabutden(an improvisatory process in which a chant melody and a written part predominantly in parallel sixths above it are ornamented by one sung in perfect fourths below the latter, and which later took hold on the continent as "fauxbordon"), the interval of the third emerges as an important musical development; because of the Contenance Angloise("English countenance"), English composers' music is often regarded as the first to sound less truly bizarre to modern, unschooled audiences.

随着John Dunstable和其他英国作曲家在一定程度上通过当地一种叫faburden的技法的运用（这是一种即兴的技法，运用于圣咏的旋律中，下方有一个主要是平行六度的部分，而它们又由一个低于下方的纯四度演唱装饰，这种后来影响了整个欧洲大陆的技法被称为fauxbordon），三度音程的出现成为一种重要的音乐发展，这是因为Contenance Angloise ("English countenance")--这种英国作曲家的音乐常常被未经教育的听众认为是一听上去就不古怪的音乐。

Tomorrow, Reader and Other Reader, if you are together, if you lie down in the same bed like a settled couple, each will turn on the lamp at the side of the bed and sink into his or her book; two parallel readings will accompany the approach of sleep; first you, then you will turn out the light; returning from separate universes, you will find each other fleetingly in the darkness, where all separations are erased, before divergent dreams draw you again, one to one side, and one to the other.
