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。
