某矿厂处理矿石13000t/d，日产出尾矿8450t，井下充填用去4850t/d，年均仍有3600t/d，即平均118.8万t/a，需74万m3/a的库容来堆存。在全部31年的计算服务年限内需堆存3683万t的尾矿，计算库容2301万m3。为彻底解决企业的铜矿尾矿出路问题，决定在某村建尾矿库。
尾矿库项目由尾矿库、尾矿输送管道、尾矿回水管道、尾矿输送泵房(现有)、移动式浮船取水泵站、管道(现有)，供电网组成。尾矿坝涉及采用碾压混合料坝，混合料的主要原料完全取自库内。尾矿坝为碾压混合料不透水坝，坝顶标高120m，坝高80m，坝长729m，顶宽4m。采用库后放矿，依托山体向坝前排尾。
拟建尾矿库库址下游为老鸦岭水库，该水库1959年建设，属小(二)型三类水库，水库集水面积为0.81km2，总库容17.9万m3，目前浇灌农田350亩(1亩=667m2)。
环评应考虑尾矿库回水是否满足农业灌溉要求。如满足农业灌溉水质要求，应根据农业灌溉的需要，采用水泵将尾矿澄清水泵入老鸦岭水库。

项目位于水库上游，环评时应该注意什么问题

The great advance (91) rocket theory 40 years ago showed that liquid-fuel rockets were far (92) in every respect to the skyrocket with its weak solid fuel, the only kind of rocket then known. (93) , during the last decade, large solid-fuel rockets with (94) fuels about as powerful as liquid fuels have (95) their appearance, and it is a favorite layperson’s question to (96) which one is "better". The question is meaningless. (97) might as well ask whether a gasoline or a diesel engine is "better". It all (98) on the purpose. A liquid-fuel rocket is complicated, (99) has the advantage that it can be controlled beautifully. The burning of the rocket engine can be stopped completely; it can be reignited when (100) . (101) , the thrust can be made to vary by adjusting the speed of the fuel pumps. A solid-fuel rocket, on the other hand, is rather (102) in construction, (103) hard to build when a really (104) size is desired. But once you have a solid-fuel rocket, it is ready for action (105) very short notice. A liquid-fuel rocket has to be fueled first and cannot be (106) readiness for very long after it has been fueled. (107) , once a solid-fuel rocket has been ignited, it will keep burning. It cannot be stopped and reignited (108) desired (it could conceivably be stopped and reignited after a pre-calculated time of burning has elapsed, and its thrust cannot be varied. Because a solid-fuel rocket can be kept ready for a long time, most military missiles (109) solid fuels, but human-piloted spaceflight needs the fine adjustments that can (110) be provided by liquid fuels.

A．big

B．large

C．gigantic
