传下来的

And forthwith their shrill little voices uprose on the air, singing one of the old-time carols that their forefathers composed in fields that were fallow and held by frost, or when snow-bound in chimney corners, and handed down to be sung in the miry street to lamp-lit windows at Yule-time.

跟着尖细的小嗓就一齐唱了起来，唱的是一首古老的圣诞歌。这首歌，是他们的祖辈们在冰霜覆盖的休耕地里，或者在大雪封门的炉边创作的，一代又一代传了下来。每逢圣诞节，田鼠们就站在泥泞的街道上，对着灯光明亮的窗子，唱这些圣诗。

And once he became a chrstian he was no longer just a nobody. There must have been a lot of slave children in the roman empire. Many was called Secundus. But only this one was recorded down.

在当时的罗马帝国中，有许多的奴隶之子，而他们也都叫西公都，但是却只有这个&西公都&被记录下来，以致到今天我们在读到使徒行传20章的时候我们仍然会读到他的名字。

In vertebrate organisms,thesignaling pathway is initiated by the binding of ligandsto the membranousreceptor patchedwhich in turn alleviates the suppression on smoothened,subsequently Smo triggers a series of intracellular events with resultant activation of thezinc-finger transcription effectors,glioma-associated oncogenes(Glil,Gli2,Gli3)transcription factor,which induces the expression of numerous target genes,such as Ptch-1,Hip,Gli1 and Wnt,that regulate proliferation,differentiation.

Hedgehog信号通路是高度保守的调控胚胎组织分化发育的通路，在脊柱动物体内，Hh蛋白与跨膜受体Ptch结合后，解除了Ptch对Smo的抑制，随后Smo从共受体上解离下来进入胞浆，将信号下传并激活锌指转录因子Gli，后者启动Ptch-1、Hip、Gli1、Wnt等目的基因的表达，进而调控细胞的增殖、分化。

Upon this occasion of removing myammunition I happened to open the barrel of powder which I took upout of the sea, and which had been wet, and I found that the waterhad penetrated about three or four inches into the powder on everyside, which caking and growing hard, had preserved the inside likea kernel in the shell, so that I had near sixty pounds of very goodpowder in the centre of the cask.

至于那两个在他们面前出现的人，也就是我和星期五，他们一定以为是从天上下来消灭他们的天神或复仇之神，因为他亲耳听到他们用自己部族的土话把这意思传来传去。他们怎么也不能想象，人居然又会喷火，又会放雷，而且连手都不抬一下，就会在远处把人打死。
