he walked so fast that none of us was his equal

Question

改倒装句
did he walk so fast that none of us was his equal，这样可以吗？

Answer 1

这样不对。应该改为：So fast did he walk that none of us was his equal.
在so... that…结构中，若将so+adj. / adv. 置于句首，则其后的主句要用部分倒装。如：
So cold was the weather that we had to stay at home. 天气太冷，我们只好呆在家里。
So much did they eat that they could not move for the next hour. 他们吃得太多了，一个小时都动弹不得。
So loudly did he speak that even people in the next room could hear him. 他讲话声音那么大，隔壁屋里的人都能听见。

Answer 2

的so . . . that倒装

·如何倒装

so后面通常接形容词或副词。

1. so + 形容词

She was so exhausted that she went straight to bed.

倒装：So exhausted was she that she went straight to bed.

结论：1）so+形容词提到句首

2）be动词提到主语前面

3）其他不变

2. so + 副词

情况一：实义动词孤零零

He played the tune(曲调) so badly that nobody recognised it.

倒装：So badly did he play the tune that nobody recognised it.

结论：1）so+副词提到句首

2）隐藏的助动词do / does / did提到主语前面

3）实义动词变成原型

4）其他不变

情况二：实义动词前有have / has / had 

He has worked so hard that he will certainly not fail the examination.

倒装：So hard has he worked that he will certainly not fail the examination.

结论：1）so+副词提到句首

2）把have / has / had提到主语前面

So fast ______ that none of us was his equal

A  he walked 

B  did he walk   

C  walked he
