As in other places, rivers in Africa often make for more neighbourliness, not less; the more countries a river passes through, the greater the regional co-operation.

正如在其他地区那样，河流贯穿的非洲大陆往往是一荣俱荣的邻伴居多，争锋造次的敌国要少。一条河流贯穿的国家越多，地区性合作也就越大。

Farewell to Hiruharama The green hills and the river fog Cradling the convent and the Maori house The peach tree at my door is broken, sister, it carried too much fruit, it hangs now by a bent strip of bark but better that way than the grey moss cloaking the branch like an old man's beard; we are broken by the Love of the Many And then we are at peace like the fog, like the river, like a roofless house That lets the sun stream in because it cannot help it.

再见吧，耶路撒冷绿色山脉还有雾的河流，修道院和毛利房屋的摇篮修女，我门前的桃子树已经被压断了，它承担了太多的果实，现在它被一条弯曲的树皮悬挂着就这样吧，总比灰色苔藓依附了枝丫，像一个老男人的鬍鬚来得好；我们也被那"太多"的"爱"给压断了然后我们在平静中如同雾霭，如同河流，如同一个没有屋顶的房子情不自禁地让那光束照射了进来。

His college thesis was on the spectacled cayman; he lived in Gainesville, Florida, where alligators sun on the paths; his favourite work involved drifting, by torchlight, in a silent punt among the vegetation mats of the Mamirauá in Brazil or the llanos of Venezuela, with crocodilians darkly all about him, or looping them up on a six-foot pole to take DNA samples from them and massage their scaly necks.

他的大学论文就是写的有眼镜状斑纹的美洲鳄；他曾经居住的地方——佛罗里达州的盖恩斯维尔，鳄鱼在小路上晒太阳；借着手电的光亮，划着静行无声的平底船，在巴西的马尔马拉或委内瑞拉的亚诺斯河流植物垫衬的水中漂流，是他所钟爱的工作的一部分，其间，黑色鳄鱼遍及他的四周，或者，把鳄鱼环绕在一个6英尺长的杆子上，以采集它们的DNA样本，然后按摩它们那多鳞的脖子。

Friendly, informal copywriting allows a more personal relationship with website visitors. a list apart singled out flickr and photojojo for an honorable mention in this department, and it's a lesson that many web 2.0 sites put into practice. webtango isn't just free, it's "free of additives, cholesterol, ozone-depleting cfcs, and most importantly, free to use". tioti doesn't just have tagging and rss, it has "tagging and rss up the yazoo".

友好，活泼的行文方式会使作者与访问者建立更多良好的关系。a list apart 功能让 flickr 和 photojojo脱颖而出就是这方面的一个好例证，这也是许多web2.0网站付诸实施的很好一课。webtango 并不仅是免费，它是"无添加物，无胆固醇，无破坏臭氧层的氟利昂，还有最重要的就是，无收费使用"。tioti不只是有标签和rss，他有"标签和rss奔涌如河流"。

There are many rivers around Bengladesh . It formed by alluviation.

这个国家的河流特别多，它就是河流冲积而形成的一个国家。

Fans of classic movies will remember the famous dueling banjos scene in Deliverance, the story of four city friends who take an ill-fated boating trip down a backwoods Georgia river.

经典电影的影迷们会记得《激流四勇士》中那一场精彩的班卓琴对决的场景。该影片讲述的是四个都市朋友的一次命运多舛的乘船去边远地区乔治亚河流区域的旅行。

The purple heather still extends for miles, with its barrows and aerial spectacles, intersected with sandy uneven roads, just as it did then; towards the west, where broad streams run into the bays, are marshes and meadows encircled by lofty, sandy hills, which, like a chain of Alps, raise their pointed summits near the sea; they are only broken by high ridges of clay, from which the sea, year by year, bites out great mouthfuls, so that the overhanging banks fall down as if by the shock of an earthquake.

现在的尤兰仍然和那时一样，它深黄色的荒地，它的古冢，它的海市蜃楼和它的一些交叉的、多沙的、高低不平的道路，向天际展开去。朝西走，许多河流向海湾流去，扩展成为沼泽地和草原。环绕着它们的一起沙丘，像峰峦起伏的阿尔卑斯山脉一样，耸立在海的周围，只有那些粘土形成的高高的海岸线才把它们切断。浪涛每年在这儿咬去几口，使得那些悬崖绝壁下塌，好像被地震摇撼过一次似的。

The paleochannel-Ⅱ might form during the Holocene Optimal period.

古河道-Ⅴ形成于风沙-Ⅱ和Ⅲ期形成之前，可能是末次冰期之前，即中更新世或更早，这时河流能够进入古松辽大湖；古河道-Ⅳ形成于风沙-Ⅱ和Ⅲ期形成之时，可能是末次冰期时期，这时河流与松辽大湖萎缩，规模减小，河流已不能进入松辽大湖，而是消失在沙地之中；古河道-Ⅲ形成于风沙-Ⅱ和Ⅲ期形成之后，可能是末次冰期末期的冰消期，这时气温升高，大量的冰雪融水进入河流，促使河水漫流，流入沙垅垅间洼地，开始造成古西拉木伦河、古老哈河与教来河水文网之间的相互联系；古河道-Ⅱ形成于全新世适宜期时期，统一的西辽河形成，伴随气候变化，出现多次风沙进退，对应于风沙-Ⅰ期；河道-Ⅰ是现在，同属于风沙-Ⅰ期，活动沙地集中在翁牛特等地。
