it strong enough to hold on to thin films of water in rocks with small pores.,B.Water in rocks is held in place by large pores and drains away from small size pores through surface tension.,C.Small pores and large pores both interact with surface tension to determine whether a rock will hold water as heavy drops or as a thin film.,D.If the force of surface tension is too weak to hold water in place as heavy drops,the water will continue to be held firmly in place as a thin film when large pores exist.,A,选项存在转折逻辑词,but,，且讲到当孔大旳时候水会变成水滴，,but,孔小旳时候就变成薄膜。主干、逻辑齐全，故正确。,B,选项错在有主干，但缺乏转折逻辑词。,C,选项也有主干，但是逻辑关系写成了并列,and,，但实际上应该是转折关系。,D,选项说当孔大旳时候变成薄膜，这和原句旳主干意思完全相反。原句中说水在孔大旳时候应该变成水滴。,For example,some early
