上上下下

Hitherto, we had never been on such a long excursion,and we were all very much excited as we set out for the hilly expanse of thehinterland behind the river, up and down we walked all day, from hill to hollow.pleasant as the scenery was, the area was economically backward, with nothingmore than little homesteads, where small-time farmers would still be doingthings like mend the hinges on their barn doors, hoe the soil, hollow out somepiece of wood to make a simple tool or hoist the hay onto their carts byhand.

那之前，我们从来没有进行过如此长距离的远足，我们向河后面的内陆多山的广袤地域出发时，都非常激动。一整天，我们在山峰和山谷之间上上下下。虽然这个地区景色宜人，但经济落后，除了小农舍外没有别的，那里面，尚未脱贫的农民可能还在做着修畜棚上的铰链、锄地、挖空木头做简易的工具或徒手把干草吊到马车上之类的事情。

Tragedy often occurs when governments come along in hobnailed boots and trample over these informal systems, as happened in the Sahel during a dreadful drought in the 1970s.

When she moved about there was an incessant clicking as innumerable pottery bracelets jingled up and down upon her arms.

I was wondered about the designer of the new hotel, was he the same as me, had he even pilgrim aged to this hotel a few times every year. Did he ever think to keep, and to reconsolidate the old things, mixing them with all the contemporary elements to make something that could last an eternity?

我在酒店上上下下逡巡，希望找回过去的点点滴滴，人犹在，物已非，阵阵的心痛绞著我，我在怀疑新酒店的设计者是否会如我过去一样的每年来朝拜圣地牙哥一番，会否也是在珍视古典的同时，加以机智的时尚因素，来美化这个大家的心中古堡。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
