Question

If we had taken such effective ______ much earlier, the river would not be polluted

so seriously now.
A．treasures B．efforts C. measures D. actions
为什么C,不选D.

Answer 1

这个题目我刚刚做完。首先我想告诉你，这两个答案都是可以的，只不过侧重点不同。来看看我的题目原题。
If we had taken such effective measures much earlier, the river ________ so seriously now.
A.would not be polluted B. would not have been polluted
我选的是A，但是答案是B。我就纳闷了这不是错综虚拟条件句吗，前面是对过去的虚拟，后面是对现在的虚拟，应该是选A的，估计答案是错了，你觉得呢?

Answer 2

你好，我来说。
take measures----采取措施
take steps-----采取步骤
take action-----采取行动（注意在这里action是不可数名词）
