would be should be区别
1.he said that would be possible to build a platform in the centre of the channel.
2.the tunnle would be well-ventilated if tall chimneys were built above sea level.
这两句为什么用的是would be而不是would?
3.he suggested that a double railway-tunnel should be built?
第3句中为什么不用would 而用should be?

1,2句中possible和well-ventilated 都是形容词,而would是情态助动词,后面必须跟个动词使用,而形容词前往往用be动词,所以是would be.
3,suggest后面跟虚拟语气,即不管后面从句主语是什么,从句中的动词都用动词原形或should加动词原形.而would的意思是"将".不符合题意.
另外,你这些句子都是新概念二里的吧.我教这个教材的.
would be语气表示肯定,一定...
should be语气委婉表示不确定,应该...
would属于情态动词，所以后面必须加动词原形，因此用would be，而非would
suggest表建议时，后面的从句需要should + 动词原形，属于虚拟语气，所以用should be
would be表示一种可能性，并没有绝对化。而should be表示了相当强烈的观点倾向性，觉得一件事情“应该”怎样。
