在so... that…結(jié)構(gòu)中，若將so+adj. / adv. 置于句首，則其后的主句要用部分倒裝。如：

So cold was the weather that we had to stay at home. 天氣太冷，我們只好呆在家里。

So much did they eat that they could not move for the next hour. 他們吃得太多了，一個(gè)小時(shí)都動(dòng)彈不得。

So loudly did he speak that even people in the next room could hear him. 他講話聲音那么大，隔壁屋里的人都聽(tīng)得見(jiàn)。

So fast does light travel that we can hardly imagine its speed. 光速很快，我們幾乎沒(méi)法像它的速度。

So sudden was the attack that we had no time to escape. 襲擊來(lái)得非常突然，我們來(lái)不及逃跑。

類似地，當(dāng)such…that…結(jié)構(gòu)的such…置于句首時(shí)，such后的句子也要使用部分倒裝。如：

Such a nice man did he seem that we all believe him. 他像個(gè)很和藹的人，所以我們都喜歡他。
