    1. One desperately-needed application would be that of water purification.

    請問上句為何會用be that of 這是什麼文法?

    [說明]be是本句的動詞,that是代名詞,代替 application,因為英文有用代名詞代替重復出現的名詞的習慣。

    全句的意思是 One desperately needed applicaton would be the application of water purification.

    前後共有兩個名詞片語。

    2. the same...as / the same...with / the same...that 有什麼差別?

    [說明]the same ... as後面接名詞或名詞子句(因為as在此是當介系詞用):We were staying at the same hotel as our parents.

    the same ... that後面接形容詞子句(因為that在此是當關係代名詞用)Was this the same Timothy Evas that Carol had been at school with?

    the same ...with好像不是常用片語,字典沒看到有關例句。

    3. Nanomachines introduced to polluted water could kill harmful bacteria.

    請問上句為何會有兩個動詞 那個to又是什麼 這是什麼文法?

    [說明]本句的動詞是kill,introduced和polluted都是過去分詞,當修飾語(被動態),introduced修飾主詞nanomachines,polluted修飾water,因為只有一個字,所以放在water前面。to是介系詞,幫助形成片語。introduced to polluted water是分詞片語,因為長,所以放在其修飾的主詞後面。

    奈米機器用在受汙染的水時,會殺死有害的細菌。
