Environmental protection is of great significance.
参考答案: C
参考解析: 环境保护至关重要。strength“力量”,如:He pushed against the rock with all his strength.他尽全力推那块石头。influence“影响”,如:The media has a powerful influence on public opinion.传媒对典论有很大的影响。importance“重要性”,如:She realized the importance of eating a healthy diet.她认识到饮食健康的重要性。effect“影响,效果”,如:Too much sunlight can have side effect on skin.过多日照对皮肤会产生不良影响。只有importance意思上和significance最接近。
