關於英文over two years of construction的句型問題。?

讀英文不要太死板，「建造的兩年餘」讀起來怪怪的，那換個角度，唸成「兩年餘的建造」如何？

英語 A of B 的構造，不是絕對從後面看起，解釋為 「B 的 A」，有時是 「A 的 B」，特別是 A 是數量或時間單位時：

a cup of water
一杯的水 （一杯水）

two years of learning
兩年的學習 （兩年學習）

這裡 over two years of construction 就是「超過兩年（的）建造」。

但其實這句的學習重點應該在 just 這個字，這裡 just 不是「剛剛」、也不只有「僅僅」的意思。 just 在這裡是 slightly、 a little 「稍稍」、「些微」。所以：

The Eiffel tower was built in just over two years of construction
= The Eiffel tower was built in slightly over two years of construction
= The Eiffel tower was built in a little over two years of construction
艾菲爾鐵塔僅用稍微超過兩年的建造即完成

逗點後的 a miracle in those days 確實是省略用法，省略連接詞、主詞、動詞，不過用 and it was 不好， 應該用 which was，也就是文法上所謂關係代名詞 which 代替前面整句，表示「前述之事」，因而整句的理解應該是：

The Eiffel tower was built in a little over two years of construction, which was a miracle in those days.
艾菲爾鐵塔僅用略微超過兩年的時間即建造完成，這在當時可算是一個奇蹟。

In this pattern the S+vt is followed by an adverbial phrase of duration, which is obligatory.With verb marked "which is"="And it is" to be ommited in (which is) a miracle in those days."Which" is the relative pronoun as the subject of the verb "was built" in the main clause.
The Eiffel tower was built-----------Subject + vt.
in just over two years of construction------adverbial phrase and is a prepositional phrase;(just=only;merely;introducing adverbials of time=when=adverb phrase of time.)
(which is) a miracle in those days--------adverbial phrase.
