C

克 应该是课

1. The Province Makes Remarkable Achievements in Energy Conservation During the "Eleventh Five-Year Plan" Period, Thanks to Joint Efforts and Perseverance
2. Inspired by the Achievements and Continuing the Efforts, Let’s Work Hard to New Progress in the Total Emission Reduction during the "Twelfth Five-Year Plan" Period
3. Developing Low-carbon Economy, the Greatest Challenge for Humanity in the 21st Century
4. Implementing Low-carbon Development to Alleviate Climate Change
5. Options for Steel Plants in Desulfurization Technologies against Flue Gas from Sintering Machines
6. Thoughts on Promoting the Healthy Development of the Wind Power Industry

1.conquer the difficulties .conquer 有征服之意,是及物动词,直接加上"困难"的名词,即为克服困难
2.overcome the difficulties.overcome是克服之意,也是及物动词,与上一词条类似
3.get over sth..get over 为及物动词短语,直接加宾语

解题思路：（1）石雕放在水平基座上，对基座的压力等于它自身的重力G，即F=G；
（2）已知石雕与基座的接触面积，因此对基座的压强P=[F/S]．

已知石雕的质量m=5×10⁴kg，石雕放在水平基座上，因此对基座的压力F=G=mg=5×10⁴kg×9.8N/kg=4.9×10⁵N，
石雕跟基座的接触面积S=10m²，
∴该石雕对基座的压强P=[F/S]=
4.9×105N
10m2=4.9×10⁴Pa．
答：石雕对基座的压强为4.9×10⁴Pa．

点评：
本题考点： 压强的大小及其计算．

考点点评： 本题考查了重力的计算和压强的计算，计算难度不大，比较简单，但需要注意物体放在水平面上时，对水平面的压力大小等于它的重力．
