①下列对本诗的理解，不正确的一项是（3分）
| A．前四句问精卫：万事皆有不平，你何必目空一切，自讨苦吃，以微小的身躯衔木填海不止？ |
| B．五至八句精卫回答：我誓要填平东海，纵然力竭身沉，也绝不改变，大海不平，心无绝期。 |
| C．诗歌前八句采用一问一答的对话形式，明确地揭示了精卫矢志平海、不惜捐躯的崇高精神。 |
| D．诗歌末三句感叹西山衔木之鸟虽多，可是那些鹊、燕之类来来去去，却都只是为自己做窝。 |
（10分）碳酸钙常用作牙膏的摩擦剂。某同学设计了一种制备碳酸钙的方案，其流程图如下。（所用石灰石含有杂质SiO2）
回答下列问题：
（1）充分煅烧110吨石灰石得到固体66吨，则石灰石中碳酸钙的质量分数为 %。
（2）假设第①步反应完全进行，则第②步反应过滤后得到的不溶液性滤渣的成分为
。
（3）第③步反应一般不采用通入CO2的主要原因是 ，相应的离子方程式为 。
（4）CaCO3是一种难溶液物质，25℃时其KSP=2.8×10-9。现将等体积的CaCl2溶液与Na2CO3溶液混合，若Na2CO3溶液的浓度为2.0×10-4mol/L，则生成沉淀所需CaCl2溶液的物质的量浓度最小是 。
