1，The use of chemical pesticides in this country is (equally extensive or more so than ten years ago.)
equal to or more extensive than ten years ago
as extensive as ten years ago or more
equal to, if not more, than ten years ago
as extensive as it was ten years ago, if not more so
本题的正确答案是E请教if not more的用法。
还有B为什么错误？
2。there is no certainty/doubt that 的表达是否错误？
there be 句型后面是否可以接抽象名词？LZM的总结是不是不很准确？
偶的语法真的很菜，先感谢大家的热心帮助了。

there is no certainty/doubt that 的表达没有错，比较啰嗦作者: 新鲜 时间: 2003-2-20 21:54
那么it is by no means certain that 的表达不罗嗦吗？为什么它可以是正确答案呢？作者: Louisa_xy 时间: 2003-2-20 23:38
对不起...
there is no doubt that...肯定是有的
there is no certainty that...这种说法没有见过
常见的certain的用法：
it is certain that...
be certain of ...
be certain to do..作者: 新鲜 时间: 2003-2-22 16:13
