30.The rapid growth of the world’s population over the past 100 years (have) led (to a) great (increase in) the acreage of land (under cultivation).

答案：A;但我觉得C是不是应该改成increasement啊？高手指点，拜谢！


34.(Many of) the fine-grained varieties of sedimentary rocks (known) as shales yield oil (when distilled) by (hot).

答案：D;但我觉得B是不是应该加上were啊？高手指点，拜谢！

30 没有increasement这个词，increase本身就可以当名词，所以c没错。a的错误很明显，主语growth是单数，所以have,就得变成has.

34 Many of the fine-grained varieties of sedimentary rocks (which were)known as shales yield oil when distilled by heat.

蓝色的地方是是定语从句修饰rocks，黄色的是全句的谓语，如果照GG那样说加上were,那末全句就有两个谓语，造成了动词冲突，所以不对。

加油，祝好运。
