it is important that 虚拟语气与 接不定式的区别

Answer 1

it is important that虚拟语气与接不定式的区别：英语发展的趋势是虚拟语气逐渐被陈述语气形式代替。that从句中的动词原型式虚拟语气在英国英语常用should do代替。在非正式语体中，英国英语还可以用陈述语气。例如：

I suggest that he come tomorrow.美式英语

I suggest that he should come tomorrwo.英式英语

I suggest that he comes tomorrow.英式英语非正式语体

这种that从句用陈述语气形式，国内英语教学没有涉及。但雅思考试考的是英式英语，在阅读文章中就可能出现这种非正式的英式英语用法。
