The cradle - rockers had done hard duty for so many years , under the weight of so many children , on that flagstone floor , that they were worn nearly flat , in consequence of which a huge jerk accompanied each swing of the cot , flinging the baby from side to side like a weaver s shuttle , as mrs durbeyfield , excited by her song , trod the rocker with all the spring that was left in her after a long day s seething in the suds
那个摇篮的摇轴经历过无数孩子的重压，在石板铺成的地板上已经辛辛苦苦地摇动了许多年，都差不多快要磨平了，因为摇篮的每一次摆动而引起的剧烈震动，都要把摇篮中的孩子像织布的梭子一样从一边抛到另一边。德北菲尔德太太在洗衣盆的泡沫里已经劳累一整天了，在她的歌声的激励下，用她身上剩余的力气踩着摇篮。
