英語 as 引導讓步狀語從句

題目：

英語 as 引導讓步狀語從句
Though i was interested in sea there is nothing i can do but wait now.
Sea as i was interested in there is nothing i can do but wait now.
上面的as引導讓步從句的倒裝對麼?
在 從句結構爲 be +形容詞 +介詞短語 時 as 引導讓步從句是如何倒裝的?爲什麼

解答：

Sea as i was interested in there is nothing i can do but wait now.這個句子是錯誤的.
以as,though引導的讓步狀語從句多用倒裝語序,即把在從句中作表語的名詞、形容詞,或修飾謂語動詞的副詞放在從句謂語之前.當作表語的單數可數名詞位於句首時,名詞前的不定冠詞要省略.如：
Scientist as he is,he is very modest.儘管他是一個科學家,他很謙虛.
Strong as you are,you can't beat me.儘管你很強壯,你打不過我.
Hard as he worked,he couldn't get a pay rise.儘管他工作勤奮,他不能加薪.
上面名詞、形容詞、副詞的例子各舉了一個,
Sea as i was interested in there is nothing i can do but wait now.這句話爲什麼錯了呢?因爲sea是介詞in的賓語,而不是表語（只有系動詞後面的成分才是表語）.這句話可以改成：
Interested in sea as I was,there is nothing I can do but wait now.
