During the last interglacial period, the climate on the Earth was warmer than it is today, and the consequent melting of the polar ice caps caused the sea level to raise about 60 feet over and above what its height presently is now.
sea level to raise about 60 feet over and above what its height presently is now
sea level to be raised over its height presently about 60 feet
sea level to rise about 60 feet above its present height
level of the seas to rise over and above its present height about 60 feet
level of the seas to be raised over their height, now about 60 feet
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
over/above是介词，接名词，A后面的sth is 是个句子，错误
C，cause the sea level to rise about 60 feet above its present height，60 feet是名词，作rise的宾语，above its present height作定语，修饰60 feet，超过它目前高度的60尺。
B, cause the sea level to be raised over its height presently about 60 feet, presently修饰raised，引起了海平面现在上升超过它的高度60尺，不是现在上升，是超过现在的高度
increase/decrease/rise/decline/quicken/slow，“增加/减少/上升/下降/加快/减慢”，不管是人还是物、指标都可以用主动式，如：
The price/rate/population/number increases. ；We need to increase productivity. 我们需要提高生产力。
