问题描述：
so...that是部分还是完全倒装?
例句
1.So clever is he that he can work out all the
difficult problems in the book． （全部倒装）
2.So fast does he run that he is far ahead of others.（部分倒）
答
首先,你要弄清楚什么完全倒装,什么叫部分倒装.
1.如果全部谓语放在主语之前,叫完全倒装；
2.如果只把助动词或情态动词放在主语之前,则叫部分倒装.
一般来讲,so / such等表程度的副词放在句首时是部分倒装,但有时要看情况而定.
现在我们来看一下你给的例句：
1.So clever is he that he can work out all the difficult problems in the book．[由于so引导的句子的谓语动词只有be动词is,而is放在主语he之前,所以也可看做是完全倒装.]
2.So fast does he run that he is far ahead of others.[由于so引导的句子的谓语动词是run,而只有助动词does放在主语"he"前,所以叫部分倒装.]
