即使没有这场席卷全球的金融危机，中国的未来也充满着不确定性。在达到了人均2000～3000美元的发展高度以后，中国经济究竟还能不能持续、健康地保持高速增长，是一个没有确定解的问题。没有非常明确和确定的规则，市场中人的努力和注意力，同样不可能集中于结果不确定的经济竞争，也就无从动员人们勇敢地面对未来市场的不确定性，尽最大努力争取收益、避免灾祸。
这段文字主要想告诉我们( )。
A．可靠的企业制度具有基础意义
B．强大的国家要靠有效的税收来维持
C．中国经济需要以规则的确定应对结果的不确定
D．法律要有很高的稳定性和可靠性
参考答案：C
解析：本题考查文段主旨的归纳。文段首先明确指出中国的未来具有不确定性，接着“没有非常明确和确定的规则”一句指出经济发展中规则的确定性具有重要的意义。因此只有C项说法符合题意。A项、B项和D项三项企业制度、税收和法律是具体的规则，因此说法都带有片面性。故选C。
