★這是一個完全倒裝句。這個句子由于主語較長，為避免句子頭重腳輕，往往把介詞短語或其他成分提到句首。這種句子的謂語多為連系動詞以及l(fā)ie, stand, sit, fly, come, go, run, rush等動詞。

★ 辨析：so…that, such…that

1）so…that與such…that都表示“如此……以致……”。它們用法的區(qū)別在于搭配不同：so是副詞，所以后接形容詞或副詞，而such是形容詞，所以后接名詞。例如：

2）但如名詞前有表數量的many，few，much，little修飾時，則要求用so。即：so＋many (few, much, little)＋名詞＋that從句

用so…that…和such…that…填空
