b.That technological
c.Although technological
d.There is technological
请问为什么选b,什么语法?

Answer 1

选择C .
句子的正确结构是:
It is a fact (accepted by economists) that progress helps to relieve scarcities .
这个句子是 强调结构.
基本结构是 It is ...that .
上面 括号 里 是定语重句,被经济学家 所接受 的事实.
句子复杂是因为 这个句子
1 强调结构.
2 定语重句
3 把真正的主语放到了前面.
