全部倒裝be，動詞提前的情況

部分倒裝：只把系動詞，情態動詞，助動詞或表語放在主語之前。完全倒裝：整個謂語移至主語之前。如果謂語只有一個be動詞，那就看不出來了，看其他謂語比較明顯，比如Never will I forget the days when you were with us.這裡謂語是will forget，但只有will提前了，這就是部分倒裝。Nowhere have I been to since I came back from Beijing.這裡謂語是have been，但只有助動詞have提前了。

原句：He cannot sleep because he is too excited

全倒裝：Being too excited，he cannot sleep

原句：He counted from 1 to 100 in order，sleep

倒裝：In order to sleep，he counted from 1 to 100

be動詞提前。

例如：

Not only am I a teacher， but also a good soccer player.
