1·In particularly wet years, short stretches of an otherwise dry stream-bed may have flowing water because the water table rises to intersect the land surface.
在气候特别湿润的年月里，平常干涸的河床下游可能会有水流动，因为地下水在那里位抬升到了地表以上。
2·In both images, white clouds cast their shadows onto the land surface below.
在那两张照片里，白色的云把他们的影子投在下面的地表上。
3·Although the different models predict different details, they agree that the fire risk will change for about a quarter of the land surface.
虽然不同的模型预测不同的方面细节，他们都表明约四分之一的地表火灾风险会变化。
4·Scientists have carefully checked these observations to exclude observational errors and other influences - such as the urban heat island effect and localised warming due to land surface changes.
科学家们谨慎地监测那些观测，以排除观测误差和其它影响，诸如城市的热岛效应和由于地表变化导致的局部升温。
5·Some critics argue that the global record of land surface temperature over the 20th century could be to some extent corrupted by heat from towns and other factors.
有批评人士指出，在20世纪，全球地表温度的记录在一定程度上可能被城镇带来的热量以及其他因素侵蚀过。
1·They may only cover 5 per cent of the world's land surface, but they emit three quarters of its greenhouse gases.
也许城市仅仅覆盖了世界地面的5%，但是，它们排放出四分之三的温室气气体。
2·Humans take up 83 percent of the Earth's land surface to live on, farm mine of fish, living just a few areas pristine for wildlife, according to a new report recently.
根据最近一份新的报告，人类占据了地球地面的83%，在上面生活、耕种、采矿和捕鱼，只将少数未开发地区留给了野生动物。
3·When a hurricane moves off the ocean and travels inland, friction between the rough land surface and the winds finally slows the storm down.
飓风离开海洋，刮向内陆时，风与崎岖不平的地面发生磨擦，终至使风暴速度减缓下来。
4·In this paper, two wet springs and two dry springs of North China have been chosen to study the effect of large-scale persistent rainfall anomalies on the land surface processes in semi-arid regions.
本文以华北地区春季两个多雨年和两个少雨年为例，研究半干旱地区大范围持续性降雨对地面物理过程的影响。
5·The interior failure mechanism of rock strata developing from large-scale excavation and the rules of land surface deformation are analyzed on the base of careful investigation.
在详细调查的基础上简要分析了地下大面积采空后岩土内部破坏机制和地面变形规律。
