increasingvolumeoftourists,….以往，漓江的水质因游客量的增长遭到了严重破坏，……volume

n.量；体积；（成套书籍中的）一卷volume作为名词，常用来表达“数量”意义，其数量概念大多与体积、容积有关；也与整个物体的移动过程有关，常表达流量、吞吐量、消耗量、工作量等，例如thevolumeofrainwater，somuchvolumeoftraffic，thevolumeofwork等。【词语辨析】volume,quantity,amount

volume,quantity和amount都可以表示“数量”概念，但三者在实际的使用中略有差别。quantity表达“数量；数额”等含义时，用以说明事物“多少”的问题，常和large,enormous,high以及small,limited,minimum等程度形容词连用组成短语。这种表达数量的短语既可以修饰可数名词也可以修饰不可数名词，例如：alargequantityofwater,alimitedquantityofservices等。amount可以用作动词，意为“总计；共计”；也可以作名词，用来表达“总量”或“数量”之意义，常用来修饰不可数名词。例如：theamountofmoney,amassiveamountoftime,hugeamountoffood,theamountofyourinvestment等。2.Thesechemicalsledtoseverewaterqualityissues,causingadecreaseinthenumberoffishspecies.

这些化学物质导致了严重的水质问题,造成了鱼的品种数量的减少。【句型剖析】causingadecrease...为现在分词作状语。现在分词和动词不定式作结果状语的区别(1)Theearthquakehitthearea,causingagreatlossineconomy.(现在分词表示自然而然的结果)(2)Hegotupearlytocatchtheearlybus,onlytofindthatthebushadleft.(动词不定式表示意料之外的结果)3.Localofficialswereconcernedthatthepollutionwasdamagingthenaturalenvironmentandfeltthaturgentstepsshouldbetakentorestoretheriver’soriginalbeauty.当地官员担心污染正在破坏自然环境，认为应该采取紧急措施恢复河流原有的美丽。restorevt.
