[高一英文] as well as和in addition to有什麼差別? (In addition to/As well as)doing the homework,students need to review the lessons after classes.?

as well as是「對等相關連接詞」
in addition to是「片語介系詞」
用在你的句子裡時，兩者的意思都是：還有
兩者都是用來追加附屬資訊的

原句須採用 in addition to + 名詞 或 Ving
In addition to doing the homework, students need to review the lessons after classes.

as well as 是對等連接詞，如同 and
Students need to review the lessons, as well as (to) do the homework after classes.
As well as 罕見置於句首，是否有適當的例子，我不確定，須再查證。

雖然在翻譯字義(或查字典)上來說，in addition to和as well as可能都解作"還有"(還要)等，但是以下說明使用上在句子時的含意或傳遞意思分別：

首先，as well as不會放在句首。連接的方式必定先，A...., as well as B.
因此假如問題的"空位"是句首，選擇上差不多可以否定as well as.

其次，英文人說as well as一般是指兩樣東西是"同等重要"的。但in addition to A, ...B，有些時侯含意上第一樣東西A是主要的，B是加上去的，B的重要性或相對A的關係則要看真實內容的意義。

例如你提出的例句：In addition to the doing homework, students need to review the lessons after classes.
無論你的老師或是同學，我相信這句子的內容傳遞的含意應該"做功課"先(較重要)，而"溫習"應該在意識上是"做完了功課"後才做吧。所以這兩樣"說明"未必是平等/對等/同重要吧。

因此說話/句子的意思先決，才考慮用那一種詞彙，再以該詞彙的文法/語文規則組成句子。[一般外語學習的分析教育是"學習詞彙"，"學習分析文法"，"學習組句"...但卻少有鼓勵考慮你想表達甚麼或怎樣表達。]
